Why Do Students Learn About Science and Technology?

Science and technology education (S&T education) stimulates a curious, inquisitive and problem-solving view in children. By addressing Researching and Designing Learning they develop 21 e century skills such as critical thinking, initiative, ingenuity and creativity. Skills that are important for the labor market of tomorrow, for those professions that we do not yet know what they will look like.

To start early

Engineering and technology are becoming an increasingly important part of society. Every year, tens of thousands of technical jobs are created in some countries and the demand is only increasing. All hands on deck, therefore, to interest as many young people as possible in a technical career. To achieve that, you cannot introduce children to science and technology early enough. Research shows that students who come into contact with technology in an enthusiastic way at a young age are more likely to choose a study in that direction later.

Talent development

The more you stimulate those talents, the greater the chance that they will surface and develop. S&T education is ideally suited to make an important contribution to talent development. It invites them to investigate and come up with creative solutions.

Inquiring & Learning by Design

S&T education based on Inquiry & Design Learning is in line with the perception of children. Experimenting with children teaches them a lot. Inquiring Learning responds to their natural tendency to explore and find out how the world works. When a piece of wood floats, what causes it to do so? Is soda bad for your teeth? How does a forklift work? With Design Learning, the emphasis is on coming up with a solution or product. Can you make drinking water from seawater? How do you fold an airplane that floats for as long as possible? When children consider these kinds of questions, they learn a lot. Not only about the subject, they also learn to work together, to think independently and critically, to come up with and present creative solutions.

Mastering Inquiry & Design Learning

  • You can read more about the principles of R&D learning in the folder ‘Investigative & Design Learning is the future’ .
  • The workshop ‘Investigative & Design Learning for school leaders ‘ gives administrators and directors insight into what is involved in the implementation of Investigative & Design Learning in the educational offer at primary school.

Contributing to core goals
S&T education according to the principles of Research & Design Learning makes a concrete contribution to the following core objectives:

  • Students learn to research materials and physical phenomena, such as light, sound, electricity, force, magnetism and temperature.
  • Students learn to make connections between the effect, the form and the use of materials in products from their own environment.
  • Students learn to design, implement and evaluate solutions to technical problems.

Some professional approach is in line with the Technology Pact. In this project, government, education and business have jointly taken up the task of improving S&T education and increasing the appeal of the technical sectors .

The Science Behind Facial Cleansing Brushes

Skincare

 

Power tools create home improvement jobs easier, but will the same be said of skincare routine? In the last several years many motorized cleaning brushes have emerged in the marketplace with promises of some thicker cleansing and much more luminous skin.

“For a lot of the patients, the cleanup brushes are excellent,” states Papri Sarkar, MD, a dermatologist at Brookline, MA. “Cleansing is among the most essential measures in a skincare regime,” she states, therefore a system that may make cleanup more successful can be a highly effective instrument for healthful skin.

The brushes, like the ones featured at ponfish.com, normally use a battery-operated engine that moves the brush head in a constant movement. “Many use circular movement and others go back and forth, however, it is the repetitive movement of these bristles along with cleaner which makes them function,” says dermatologist Neal B. Schultz, MD founder of DermTV.com.

The engine and bristles allow those tools to wash dirt and cosmetics from exfoliating and skin more efficiently than simply washing by hand, however, Sarkar claims the resources have more persuasive advantages.

“Because they provide continuous pressure and several possess sockets, these brushes are a more standardized means to wash than simply with your hands,” she states. Another benefit: The brushes glow therefore nicely any skincare products you employ after washing are consumed readily.

The amped-up cleanup is particularly effective for anyone who has acne, Sarkar states. But aging or sensitive skin might require a more gentle solution: “If the skin is irritated or red, a brush might not do the job for you.”

Schultz cautions that overuse is a frequent issue. “It is possible to get first-degree burns off too-aggressive cleansing,” he states.

The brushes range in cost from approximately $20 to $200, so what is the distinction? They might use distinct bristles or possess a stronger motor, however, the 200 brushes aren’t automatically 10 times as powerful as the $20 choices, Schultz states.

Start looking for a cleaning brush with bristles instead of an oscillating mind, Sarkar states, since the brushes have a tendency to be more abrasive than these versions with horizontal pads. “I enjoy the Clarisonic,” she states. “The sonic tech is excellent for cleansing, along with the brush has become the best and gentle I have attempted up to now.”

Brush Hour

Sarkar shares her tips with a cleanup brush.

Eliminate makeup

If you put on a heavy coating of the base, the brush can not wash also. Sometimes, washing makeup on may lead to irritation and allergies. Utilize makeup remover or even some cleaning towelette first.

Use a mild cleanser

Start looking for something that’s perfect for your skin type and also lathers to your most effective clean. Avoid scrubs using abrasive particles.

Do upkeep

Change the brush heads in line with the brush’s directions. A buildup of grime and germs could trigger breakouts.

Restrict yourself

Considering that the brush dries, utilizing it over daily could be too harsh to the skin. Save for day cleaning so that you may wash your day’s dirt, perspiration, oil, and cosmetics farther down the drain.

Know when to Prevent

In the very first sign of redness or irritation, turn off the device. Give your skin a couple of days to recuperate before studying to see whether you’re able to endure the brush a couple of times per week.

 

How Technology Improves Art

Regardless of our occupation, it’s essential for us to stay acquainted with best practices and combine technology into our classrooms. Not only because it helps encourage our students’ 21st-century learning skills but because it can be an entertaining and fun addition to the art room especially with a gaming chair from housetech.

1. Technology provides students a new way to express art.

Technology in the art studio is a wonderful way to get your students using various type of mechanisms. There are plenty of apps with which students can generate their own art as well as manage the classical art they have made.

2. Technology provides several apps that allow for the alteration of classical art.

Students have the chance to convert art they have built with different apps. There is also a term called “app smashing” in which students can utilize more than two applications to transform their artwork. For instance, students can take a photo of a sketch and edit it with a particular app. From there, he/she could take it into another application to make different enhancements. This works well with photography subjects, as well.

3. Technology permits for flipped training.

Flipped learning can be a wonderful way to share knowledge with your students without always repeating what you say. If a student is tardy or away, they can watch video presentations designed using technology such as iPads.

5. Technology expands possibilities for research.

Kids love technology! They contribute innumerable hours on their electronic devices. Using these tools to profit students educationally can be a great way to get them involved in research for class homework.

7. Technology makes education enjoyable.

Seeking a method to make learning more enjoyable is important. Learning new ways to distribute information, encourage student collaboration, and promote 21st-century skills can not only be advantageous for promoting critical thinking, presentation, creativity, and collaboration but it can also be enjoyable.

Link Between Science & Computer Game

Digital games are an important medium of communication, entertainment, education and business. They have one thing in common, they are programmed.

The video game industry such as is a winner in the past few years. One of which is the god simulator game. Now gamers have even discovered the research. With an unusual action, they are helping scientists to gain new knowledge. The manufacturer of Borderlands Science gets prominent support from a star of the series “The Big Bang Theory”.

Computer games and science

When research meets computer games, it is of course playful. The successful shooter game Borderlands 3 uses this via a reward system built into the game. Here players have to achieve success in a world between western, sci-fi and fantasy.

For the successes achieved, they receive points, which they can exchange for rewards. Whoever plays is paid in fictitious currency similar to the real world. Scientists now want to use this reward system. In the in-game game Borderlands Science, a game within the game, there is an old arcade slot machine. Anyone entering Doctor Tannis’ infirmary can play a round of arcade games at this old machine and collect points in the service of science, of course.

Because the data for the puzzles that have to be solved there come from microbiome research. The microbiome is the entirety of microorganisms that live, for example, as bacteria on and in humans.

And the solutions from the game help to decipher this data and, for example, to better understand our intestines, which we also call our second brain, but still do not really know it.

A computer sandbox game: Celebrity support from “The Big Bang Theory”

Game manufacturer Gearbox explains it to its gaming community as follows. “The human gut is related to many ailments and diseases. This includes obesity, diabetes, depression, anxiety, autism and more. By plotting these microbes, the scientists hope to be able to better know these ecosystems, which can lead to future research into new treatment methods and interventions. ”

The game gets prominent support from Mayim Bialik. In the hit sitcom The Big Bang Theory, she plays Dr. Amy Farrah Fowler. In contrast to her fellow actors, she is also a researcher, a neuroscientist, in real life. In a video, she explains how the game works for science.

Learning To Pave Your Driveway

Your house is almost finished, but there is still a lot of construction around it like the driveway. Thus, create a driveway that the whole street will envy you for. Get ideas at or ask their experts to do the paving for you.

Paving the driveway: How extensive should it be?

resin driveway

You can pave a courtyard entrance very pragmatically. But you can also really put your brains into it and implement the entrance to your street. With paving stones that show your pride, drainage channels, palisades, and gravel around the facade, your driveway will surely be a work of genius. It is amusing to see a house entrance with steps, raised beds, the right green and everything with the right LED lighting.

For a large-scale driveway, you can therefore plan earnestly. Of course, it goes faster with more helpers and professional assistance.

Planning your entrance: Tips & tricks

  • Make a sketch and precisely measure your entrance.
  • Right from the start, think about what you want to redesign and how you want to create which areas.
  • Do not skimp on the work for the underground of your driveway. Otherwise, you will be annoyed later about uneven surfaces and puddles that you have to wade through.
  • You plan a drainage channel at the deepest point.
  • Take into account existing water drains and supply shafts.
  • Note the transitions to other surfaces.
  • Plan wiring for lamps.

Ideas for your individual driveway

With the choice of materials, their color, shape and size, there are numerous possibilities. And the different plants and light effects are not yet taken into account. Numerous variants are available for your own project.

You can combine different materials with each other. That is particularly appealing. Make sure that you stick to one color scheme, as the combination of different materials generally looks a bit more restless. So combine, for example, light gray gravel with gray slabs and dark gray palisades.

Always mix paving stones from multiple pallets before laying them. This way, you avoid unwanted colored edges in the paved area.

In the end, you set accents with plants and LEDs. A flowerbed on the edge or a section of lawn with some green can loosen up large driveways a bit.

Learning About Link Building

Link building is all about hyperlinks directed to your website. What is the power of link building?

  1. Hyperlinks create more traffic. The more traffic a site has means the site has a very good advertisement. These traffic will make the site visible and rank high on search engines. The higher rank a site acquires, the more credible it will appear. People will only trust and visit credible sites. In short, links give sites credibility.
  2. Link building has guest post services. Guest post service is also known as guest blogging. Meaning, you or a writer will create a post or a content for another site then will add a hyperlink directed to your site. In order for the guest blogging to work, make sure to choose a reputable site as well. If a writer will guest post in a reputable site, it will appear like a collaboration between two reliable websites that people can trust. You may want to consider availing guest posting service from outreachmonks.
  3. Through links, your site will be exposed and will create a trusted brand. Other sites who have the same niche will also be interested to guest post on your site which will again, create traffic that will give you a higher rank on search engines.

Mentioned above are some of the advantages of link building. However, if you really want to achieve real success, do not just depend on buying links. Take into account that not all links will work for your site and might affect your site negatively in the future. Instead, make your site known to high authority websites. Establish good rapports with other people of the same niche. If you received a favor, make sure to return it. Be patient and use other channels to advertise or market yours. Be consistent with the content and always aim to improve.

 

Philosophy Of Science And Health

If we have a medical or psychological problem, we go to a specialist who puts a name on it. Then we receive a matching treatment. For example, if you have a gut problem, you go to a doctor who may recommend to reset your gut which could mean detoxifying through the help of oral medications. 

We are too quick to ignore how imprecise that approach can be, says Pieter Adriaens professor of philosophy.

Philosophy of Science and Healthcare

Pieter Adriaens has recently published three handbooks in which he explains how philosophy works, for bioengineers, biomedical scientists, and psychologists respectively. Adriaens is unraveling current issues of care and ethical paradoxes in his books. In Thinking about bodies, his most recent book, he talks about medicalization, obesity, and human handicaps, among other things.

For example, Adriaens describes how the World Health Organization (WHO) classifies obesity as a disease, which can be helpful in treating some patients but can also have harmful consequences. Not every person with a pound more suffers from a disease, so stigmatization is undesirable. Scientific supporters of Fat studies are diametrically opposed to this. For them, obesity is the result of a diet that is poorly adapted to our sedentary life. They also cite a psychosocial cause.

Obese people are not sick themselves, but the persistent stigmatization makes them more susceptible to psychological problems. Adriaens uses the example to show that we do not always use rational arguments when determining syndromes (and their treatment).

Philosophy of Science

In modern times, probably no branch of philosophy is as relevant as the philosophy of science. Philosophy of science is a discipline of philosophy that deals with the critical examination of the presuppositions, methods, and results of the sciences. That is now more important than ever, now that technological progress is going very fast and we are always going one step further. Science is essential in our civilization, but we sometimes forget to consider why, and whether all this progress is going in the right way. The philosophy of science helps with this.

The questions that philosophy of science poses

What Determines Good Science? Who makes the decision? What are the ideological frameworks that occurred in science? Philosophy of science is a philosophical concept that examines how science works and develops knowledge. The study wanted to characterize and analyze the science industry, which may be historical or based on methods and techniques. Everyone wants to understand science as well as condemn it. Is this what we want? Should we be more critical, or should we engage with science more? Is that the case? All of this is discussed in the philosophy of science.

Criticism of Modern Science

There are many philosophers of science – modern and ancient, living and dead – who criticize the course of science. They argue that too much is being done without considering whether this is moral or necessary for the world. On the other hand, there are of course the philosophers for whom it cannot go fast enough, because scientific progress is what distinguishes us from other animal species.

The protection of the environment and climate plays a major role in all age groups at the beginning of the 21st century. Science, education, and consumer protection are an important part of an increasingly green economy. They lay the foundations for sustainability knowledge and thus also for sustainability action, according to David Perry.

The specific activities are as diverse as environmental and climate protection itself. In other countries, there is a four-digit number of environmentally-related courses in which academic staff, professors, or assistants pass on their knowledge to students. The school and extracurricular education system deal with even younger people by imparting environmental and climate knowledge to young people.

Alcohol & Disinfectants: Clearing Bacteria Away

Due to the influence of the new coronavirus (COVID-19), alcohol for hand disinfection is installed in restaurants and supermarkets. Consumer awareness has also changed and people are now rubbing their hands with alcohol more often than before. Rubbing alcohol is always in short supply as equipment is disinfected more frequently than before.

Review about disinfection with alcohol

Alcohol has long been used for food preservation and beverages by utilizing its bactericidal effect. Today, it is used for disinfecting fingers at medical sites and disinfecting equipment at restaurants and food processing sites. Since it can be easily purchased at drug stores, it is widely used for disinfection in general households and if there are critters pest control like Beaverton would help with that.

The bactericidal effect of alcohol and the types of alcohol.

Bactericidal effect of alcohol

The exact sterilization mechanism of alcohol is still unknown. It is generally believed that alcohol kills the virus by destroying the lipid membrane that covers it. Therefore, alcohol does not work well against viruses that do not have a lipid membrane (non-enveloped). Typical envelope viruses are influenza virus and coronavirus. Non-enveloped viruses include norovirus and rotavirus.

Commonly used alcohol

Alcohol generally refers to ethanol (ethyl alcohol). Ethanol has the same main component as alcoholic beverages for beverages, but be aware that if it is handled alone, it will be subject to the Liquor Tax Law. Therefore, alcohol for disinfection and sterilization is prevented from being diverted to beverages by adding a denaturing agent that is difficult to separate. Alcohol containing a denaturing agent is called denatured alcohol.

Alcohol type

If you go to a drug store, you will find many types of alcohol. There are four main types of alcohol.

  • Alcohol for pharmaceuticals used for therapeutic purposes
  • Designated quasi-drug alcohol for hand disinfection
  • Food additive alcohol for food, equipment and utensils
  • Alcohol for beverages

The four alcohols have the same ingredients, the difference being the alcohol concentration and the presence or absence of additives .

Rubbing alcohol

Since the alcohol concentration of quasi-drugs is set at 76.9-81.4v / v%, there is almost no difference in the effect depending on the product. Some products contain additives such as glycerin to prevent rough hands. In addition to ethanol, many products containing benzalkonium, chlorhexidine lucon, isopropanol, etc. are also on sale.

Absolute ethanol

Absolute ethanol refers to pharmaceutical alcohol containing 99.5v / v% or more of ethanol. High-purity ethanol that contains almost no water. A common use is for cleaning equipment such as around the kitchen. Since it dries very quickly, it is suitable for cleaning precision machinery that should not get wet.

It cannot be used for disinfecting fingers because the alcohol content is too high and the hands may get rough when used. However, if you dilute the alcohol content to about 70-80% with water, you can use it as alcohol for hand sanitizer. Anhydrous alcohol is extremely flammable, so store and use it in a place free from static electricity.

Alcohol substitute

So far, we’ve reviewed rubbing alcohol. However, nowadays, rubbing alcohol is very difficult to obtain due to the rapid increase in alcohol usage in many places.

Beverage alcohol

The main component of drinking alcohol is ethanol, which is the same as rubbing alcohol. It depends on whether it contains a denaturing agent that is different from rubbing alcohol. The denaturant is mixed to prevent the conversion of industrial alcohol to beverage alcohol.

The Motivation To Learn: Children and Study

Does your child hate learning? Does the mere thought of school, homework, and homework disgust him? This is the road to nowhere. It is difficult to achieve good results without a love of knowledge and a desire to develop. What should parents do in such a situation?

Raise interest in the topics you study

Cramming dry theory and solving problems is a rather boring task. But there are many great ways to diversify your studies. For example, you can show your child how the knowledge gained comes in handy in real life. Invite a junior student to pay at the checkout and calculate the change on their own – this will require mathematics. Write a letter to your grandmother or an article in the school newspaper. Plant flowers on the balcony – botany to help!

Historical reconstructions, museums, entertaining physical and chemical experiments, theatrical performances based on literary works, lectures in the planetarium – all this is at your disposal. Another way to interest a child in learning is educational books and colorful encyclopedias . The material in them is presented much more exciting than in school textbooks, and some facts will surprise even adults!

Set long-term goals

What does your child dream of becoming? Maybe he loves and wants to work with animals? Explain that in this case he needs to get a handle on biology, chemistry, natural science. Or is he planning to connect his life with international journalism?

The ultimate goal – to get a favorite profession – in itself will motivate the child to do more diligently. After all, study is not just grades in a diary. This is an important step towards realizing your dreams. Later, the knowledge gained at school will help to continue education and make a career in the chosen field.

Harness the potential of board games

Board games are not only fun but also rewarding. With their help, you can train skills that will come in handy at school, and unobtrusively instill in your child a love of learning. Besides, almost every board game is a reason to tell something new. Even if you just explain to a child an incomprehensible word while playing Scrabble, then you will already replenish his piggy bank of knowledge about the world.

Be kind

While studying with a student, remain calm and positive, speak in a neutral tone. Do not transfer negative experiences to the child, create a positive attitude towards learning. It is very important to help children stay motivated by using feedback. It is best to combine praise with constructive criticism.

The sandwich method is effective. Start with the good, then point out what can be improved by focusing on the essentials. Be specific: no one is interested in listening to a long list of shortcomings. And if your car is not in its best condition reading up on north carolina lemon law lawyer can help with that.

The Science Behind a Sewing Machine and Its Benefits

Have you ever thought about the advantages that a sewing machine has to give? Well, sewing machines are soon getting a lot of attention and have become one of the most significant things that you find in all households. In this article, let us tell you some reasons why you must have a sewing machine.

1. You Must be Able to Sew Faster

We are aware that sewing using our hands takes a lot of time. This is why a lot of us do not choose sewing in the first place. Nevertheless, when you have a tool at your disposal you can rest guaranteed that the sewing can be done instantly and at a faster pace.

2. Excellent Stitches

If you would prefer to make something truly elegant and beautiful, then sewing machine shall serve you an amazng deal. In the cloth where you are stitching, it must become likely to include ribbons and other details of the painting. All complex and appealing designs will be plausible to accomplish if you have a sewing machine and are able to understand how to use the same.

3. Can be Prepared to Sew Heavy Fabrics

Fabrics like wool can simply be tailored when you have a sewing machine at your home. Wool and jeans are two materials that are very bulky and hard to work with. In the case of the above materials, efficiency is of great significance. More often than not you must not get the wanted accuracy if you attempt to make items from the above-mentioned materials by hand. Consequently, a sewing machine becomes necessary in these situations.

4. More Than Just Sew

A sewing machine can be utilized for a lot of uses. You not only sew with the use of the equipment, but there are several other uses that shall be accomplished if you are able to use a sewing machine. If you understand how to use the instrument in a correct manner, it will help you come up with lovely and excellent products. You can help your family and relatives make lovely soft toys, handicrafts, and a host of wonderful products.

BUYING YOUR OWN HUT TUB

Of course, those who are on wellness often dream of having a Wellness oasis in your own four walls to build. Some people use it to relax and unwind from stress. The first step is certainly a “relaxed” equipped bathroom and maybe follow, with enough space and the necessary small money, also sauna and whirlpool. I admit that we would not mind setting up such a wellness oasis in our small garden sooner or later. For this reason, of course, I keep the eye open, for practical tips and creative ideas for implementation. If I have the opportunity, then of course I also like to grab experts to ask for important information in peace. For example, do you know what a hot tub costs? Where you can buy a good hot tub and what to look out for when buying? How does such a hot tub work in the first place and how it is maintained? Visit ‘spa-marketing’ if you are looking for a medical spa place.

WHAT SHOULD YOU CONSIDER?

As with any product, you should pay attention to quality: Is the whirlpool from a well-known manufacturer or has you never seen and heard the brand? The same applies to the installed technology and the individual materials like the pumps, the control system and the tub acrylic. If they also come from brand manufacturers, you will still get spare parts in 15 years if necessary. It is also good if the exterior cladding and floor of the whirlpool form a closed construction. Thus, no cold, wet or small animals penetrate into the interior from the outside.

By and large, the price range can actually serve as a first point of reference. Nevertheless, you should definitely look at a hot tub before buying. Especially if you are not yet sure what exactly you are looking for and what suits you. Some like it simple and minimalistic, others want the full program when it comes to equipment. Everyone feels comfort differently.

HOW ABOUT THE MAINTENANCE?

Lower than many might imagine. At least with a high-quality device with good insulation and high energy efficiency. One often thinks of water masses, which are then kept permanently warm. However, the water remains in the whirlpool for an extended period of time. The water only has up to 40 °C when the temperature is shirled – otherwise the temperature is set down. Both water and electricity costs are kept within manageable limits. Depending on the model and the number of people, you can expect an average of 1.50 to 2.00 euros in incidental costs. That’s just as much as a coffee to go.

A hot tub is actually not much more maintenance-intensive than a coffee machine. As technical progress progresses, however, the devices become less and less maintenance-intensive. Some manufacturers even run hot tubs with maintenance-free technology – this is particularly pleasant for the owner.

Of course, when maintenance is pending, it should be carried out by a specialist. It is therefore advisable to pay attention to who will carry out the maintenance later before purchasing.

HOW OFTEN SHOULD A HOT TUB BE CLEANED?

This depends on how often and with how many people the whirlpool is used. The good thing is that a hot tub takes over much of the cleaning itself. The water is kept clean and clear by the filters, the skimmer and an ozonator or by UV-C technology. With a few simple steps, the water stays in balance without any problems. The quality of the materials used, such as tub acrylic, also plays a role. If it has a good coating, deposits have little chance. A complete cleaning is best done once a year. A good opportunity to clean the tub from the inside is of course a water change.

The Science of the Golf Swing

Let’s start with swing and impact.

When you become an advanced player, you hit the trajectory of the ball by swing, but this is not hitting with your head, it is just that your body reacts freely by the proficiency level of practice. It seems that the left and right strikes and the trajectories such as draws and fades also control the ball at the time of impact.

It is said that the contact time between the ball and the club face at the moment of impact is only 0.0005 seconds . Moreover, the time that the ball is crushed by the impact of the impact and sticks to the face is 0.0002 seconds, so if you can control it with the club face, the actual time is only 0.0003 seconds .

You can see how short this speed is.

It’s such a short time that you can’t control it freely in human work, and above all, you shouldn’t have enough time to affect the ball by swinging. It is impossible for human beings to freely control such divine moments.

That is why the swing to impact has an effect . In other words, in order to make a scientific swing, it is ideal to have a sensuous swing in which the body reacts naturally without having to think about it by repeating the practice of memorizing the correct theory in the body.

So what is the most effective thing to remember in your body?

What is important here is the face and angle that should be reproduced , not the appearance of the swinging player. Some people are striking a henna chocolate ball with no force, as the clockwork doll moves like a broken doll trying to return to the same shape as it was initially set up.

If you raise the grip from the set state and move from the top to the downswing, the position of the waist will drop and the right elbow will be like hitting. The left and right shoulders should have been in equilibrium, and the left shoulder should be raised at the time of impact. There are three points to be aware of in this pulling swing.

Do not untie the cock

In a swing that creates a long distance, it is important that the wrist does not break to the back side and the cock does not come loose .

Do not move the position of the head

The position of the head on the right side of the center of the body in the stance should be left unchanged until the impact . For that purpose, you can’t twist your body around your spine, and of course you can’t turn your left shoulder. The fastest way to slide the head at the moment of impact will increase the flight distance. In order to give a strong impact to the ball at the fastest speed, it is important not to uselessly diffuse energy in the swing and if you want to play golf with your grandparents then golf clubs for elderly is good to get.

There is a way to check with “sound” as a way to know how fast the swing is . If you switch the grip to the head and swing, you should hear the sound in the right half of your body, but you will hear the sound in the left half when you say “the head comes out better”. If you can hear the sound in your left ear, the swing is definitely faster.

How to Use Adhesive Cream Properly

 

Why adhesive cream?

Patients who no longer have their own teeth have to resort to prostheses . The artificial dentures are made individually for each patient and fitted into the jaw.

With the help of an impression material , the dentist takes an exact impression of the upper or lower jaw, which is used as a model for making the dentures. Despite this exact impression, however, it is hardly possible to fit the prosthesis perfectly into the oral cavity.

No more slipping of the prosthesis

Adjusting the prosthesis can not guarantee a secure hold . Adhesive cream is used to prevent it from falling out during everyday use, for example when eating or speaking .

With the help of the adhesive cream, the dentist is able to consume even hard, chewing-intensive foods without disturbing the third teeth.

Because the prosthesis can never be perfectly adjusted, the friction on the gums can cause sores on the jaw. The adhesive cream protects against this painful inflammation.

A slipping and sliding to prevent the daily use of the prosthesis and thus violations of the mucosa and prevent pressure points, there is the so-called adhesive creams. Adhesive creams consist largely of liquid plastic.

The effect:

Mainly swelling substances are used for adhesive creams , which in combination with the saliva form a thin and flexible cushion between the denture and the mucous membrane. Additional aromatic substances ensure a pleasant taste. It is particularly often a menthol flavoring substance , which also causes fresh breath .

The right adhesive cream
Adhesives come in a variety of forms, such as

  • Powder
  • Platelets
  • Stripes.

The best-known form, however, is the cream or paste form. Which is the most comfortable shape for the bit wearer should be determined individually. Of all the variants, the cream is the easiest to use, as it is only applied to the sides of the prosthesis before insertion. Available the adhesive are in

  • Supermarkets
  • Pharmacies
  • Drugstores

Unflavored and different flavors
Most commonly, tasteless adhesive cream is used. Although these creams are stated to be tasteless, they usually still have a slightly sour or medicinal taste.

If this taste is perceived as unpleasant, adhesive creams with flavorings are available as an alternative to the tasteless adhesive .

Advantages and disadvantages of adhesive cream with taste

A great advantage of adhesive cream with taste is that you have a pleasant and fresh taste in your mouth for a longer period of time. Due to the inherent taste of the adhesive cream, drinks and food cannot be enjoyed without this aftertaste .

The application of adhesive cream
Before the adhesive cream can be applied to the prosthesis, it must be thoroughly cleaned . There are special cleaning agents for this process , but thorough cleaning with a toothbrush and toothpaste is also possible.

It is advisable to soak the dentures overnight in a glass of water with or without agents or to clean them in a special ultrasonic cleaning device for at home. Once all leftover food and adhesive cream has been removed, the prosthesis can be inserted. In particular, residues of adhesive cream on the denture can have an extremely negative effect on the fit.

If you have to wear a full denture, the use of adhesive cream is almost indispensable like ‘denture adhesive reviews‘ it was reviewed for the buyers dentures adhesive guide. Adhesive for dentures does not only protects the oral mucosa but also prevents pressure points and ensures a fresh mouthfeel. 

MOTORCYCLE FOR BEGINNERS

You have passed the motorcycle driving test? Congratulations! Before you take your first tour, there are now some important decisions to make: Which motorcycle should be purchased? What is important for equipment? Which driving techniques help to travel safely on two wheels? Not only for motorcycle beginners, HDI’s tips on motorcycle purchase, protective clothing, riding practice and motorcycle insurance are a good basis for a safe start to their first motorcycle season. Here are some helpful tips and information for a safe re-entry. You can also check ‘hitch carriers for motorcycles‘ for hitch carriers guide.

WHICH MACHINE SUITS ME?

The first thing, of course, is to have your own vehicle. The bad news in advance: There is no perfect entry-level motorcycle. Because every person has different requirements for his bike and brings individual physical requirements with him. But there are features that make a motorcycle suitable for beginners. Essentially, it must match the driver’s stature and power and be easy to use.

Whether you have a Naked Bike, an all-rounder, a touring machine or an Enduro in mind: you can orientate yourself on the following characteristics when buying your first motorcycle.

CHEAP MOTORCYCLES FOR BEGINNERS: USED BIKES

When buying second-hand, it is recommended to take an expert person with you. Used motorcycles sometimes have defects that a layman does not recognize at first glance. Especially popular motorcycles are often cheaper to get than more unusual models. The supply of spare parts and accessories is also better for popular machines than for less common motorcycles.

Be sure to take a test drive. It gives you an impression of the driving behavior of the machine. It is also used to find any errors that occur during the journey.

 

THE OPTIMAL EQUIPMENT FOR BEGINNERS

High-quality protective clothing can save lives. Functionality should be paramount when choosing your outfit. Only then comes the optics.

Motorcycle clothing must sit. It must not be too narrow or flutter. Try several outfits, including on a motorcycle. Especially for motorcycle beginners a good tip: Buy your protective clothing in a specialist shop, which has a motorcycle ready for testing in its sales rooms. Do you check: Do you press wrinkles in the knees or in the pelvic area? Are the protectors where they belong? Do they bear the CE mark? Does the textile clothing still sit when the lining is removed? Does warming functional clothing fit under the leather outfit?

The best way to test the helmet is on a test drive. This is the only way to judge whether he is sitting correctly and how he behaves in the wind. In good specialist shops, such a test drive with the helmet that has not yet been purchased is usually part of the service.

FLEXIBLE WITH PERFORMANCE MODULES

Have you found your ideal beginner’s motorcycle? Perfect – then only the right insurance has to be come. The risk of causing an accident with a motorcycle is greater in the first years than in the following years. Motorcycle insurance is therefore the same as for car insurance: beginners pay higher premiums than experienced road users. However, after a loss-free year, the contribution decreases considerably.

The HDI motorcycle insurance protects the motorcyclist against all essential risks. You specifically insure what is important to you. With the flexible modular system, you can put together a tailor-made insurance cover, which you can adapt exactly to your individual needs. For example, full-coverage protection can be a good choice, especially for motorcycle beginners: you don’t have to worry about the cost of self-inflicted damage to your own machine.

COLLECTING AND FURTHER LEARNING DRIVING PRACTICE

The driver’s license in your pocket does not mean that you are finished with the training. Even the best driving school can’t teach you all the skills that make up a good motorcyclist. You can only acquire them yourself through a lot of driving practice. That’s why regular motorcycling is essential for beginners.

Of course, it’s fun to test the power of the engine. Constant throttle, however, often entails hard braking maneuvers. The abrupt change of pace overwhelms even beginners. Try to drive at the same pace and look far ahead and think.

Gaming for science: in research of Covid-19 

In the space game “EVE Online“, players can solve small puzzles and successfully support researchers in examining blood cells in Covid-19 patients.

In the vastness of virtual space, players of the computer game “EVE Online” have already given the hard natural science of the real world a helping hand. Recently, the team behind the successful role-playing game, in collaboration with scientists, found a surprising way to advance research into Covid-19 through gaming.

In June 2020, the game developers from the Icelandic company CCP, a science educator, a medical geneticist, a professor of computer science and a Youtuber gathered in a live stream. They presented the third edition of “Project Discovery”, a mini-game, a game within a game, to the community of players in the space adventure game “EVE Online”. In it, gamers can solve small puzzles that provide research teams with important data about the coronavirus.

“Project Discovery” combines play and research

“EVE Online” is the dream of many science fiction fans that has become a game: To fly through asteroid belts in your own spaceship and search for raw materials, scout out wormholes, engage in interstellar trade and of course fight in large space battles. For 17 years now, it has been considered one of the most complex games ever, with an enormously steep learning curve, its own economy and even player-operated stock exchanges.

Online role-playing game players have already made their contribution to science in the past. In recent years they have supported researchers in creating the Human Protein Atlas and in the search for exoplanets – and now in the fight against the corona virus. In “Project Discovery”, EVE pilots can virtually play in the cockpit of their spaceship when things get boring in the game, for example during asteroid dismantling or long interstellar space jumps.

watch the video why “EVE Online” is one of the biggest multiplayer role-playing games out there with 300,000 monthly players

Players should mark cell types in the blood of Covid-19 patients

This time they see microscopic images of blood cells from Italian Covid patients. To do this, the blood cells are marked with certain fluorescent proteins. The cell type can be recognized by how strongly the cells glow. These then appear in the recordings as groups of points on a screen.

To do this, the gamers, as “citizen researchers”, now have to draw lines around the various collections of points. By drawing clear boundaries between the clusters, they help the scientists to make the next discovery: They want to know which cell types are in which concentration in the blood in different phases of a Covid infection. Examples are T cells, red blood cells or killer cells.

It is astonishing that in times when people everywhere and especially in medicine are talking about artificial intelligence, no computer algorithm can do such a supposedly easy task. Although some programs have been developed for this task, they do not work very well. However, according to Brinkman, “humans are naturally extremely gifted at taking in visual data and recognizing patterns”

How does empiricism works.

There are basically two types of term papers and theses: theoretical and empirical. In many degree programs it is the case that surveys on academic work are part of it . The first time you conduct a survey as part of your studies, you are sure to ask yourself a few questions. We have numerous useful tips and tricks for you to make your empirical work work.

The basics for your survey

In order to carry out the survey for your scientific work, you first need certain basics. Because without the right basics, you cannot set yourself any goals and the scientific nature of your work falls by the wayside. So deal intensively with your topic, scroll through literature and deal intensively with it. Only with sufficient specialist knowledge will you be able to design a survey in a meaningful way and then evaluate the results. When doing your research, make sure that there is already a comparable survey – after all, it doesn’t make sense to reinvent the wheel. Once these foundations have been laid, the actual part of your empirical work follows: creating the questionnaire.

The questionnaire – the classic among surveys for scientific work

There are various empirical methods: In addition to experiments and interviews, questionnaires in particular are widely used. Your advantages are clear: once created, your questionnaire is the same for all participants, so that the answers are more comparable and it is therefore easy to evaluate. You can also distribute your questionnaire through different channels in order to reach as many people as possible. This is particularly important because the following principle applies to a survey for a scientific paper: the larger the sample, the higher the probability that you will achieve representative results .

 

Searching for Online Express Surveys for Your Restaurant?

Then this might be the one you’re looking for.

Have people take your survey

Many students who conduct a survey for their scientific work probably ask themselves this question. It’s best to start with a small group. Ask good friends and fellow students, if they belong to the target group, whether they will fill out your questionnaire. Your friends will usually be happy to do you a small favor and your fellow students will know how important empirical data is for your academic work. That’s why it’s also a great way to share your survey on social media: A Facebook post with a link to your survey and a request to your friends to take part and share your entry reaches an incredible number of people in a short time. Give eligible people an additional incentive to take your survey. The prospect of winning a voucher from a popular online mail order company has already led many to fill out a questionnaire. A 20 euro voucher that you raffle among all participants can turn out to be a worthwhile investment. With a little luck and friendly persistence, you will get the number of people with whom you will achieve representative results for your scientific work in the survey.

Scientific explanation of copyrighting

Are you really allowed to copy under current copyright law?

Your rights to your own work are protected by copyright. As the author, you basically determine what happens to your work. The primary concern is to what extent a work may be distributed, reproduced or published. At the same time, copyright law is committed to ensuring that scientific research is not impaired by the legal situation.

Understanding the Copyright Law

Copyright in private use
You are allowed to copy almost everything for private use, with the exception of a few restrictions. This is particularly valid if you are using the copies to fulfill your personal interests. It’s important that you don’t use the records for any commercial or technical purposes. Private copies are not limited in number by Copyright. As long as there is no commercial purpose, electronic database works can also be reproduced.

Copyright in educational institutions
Since March 2018 there has been a new “ Copyright Knowledge Society Act ” for schools, universities, libraries and other educational institutions .

According to the new rules, the following uses are possible:

  • You have permission to make copies to illustrate something in class.
  • You are also allowed to use works to produce your own teaching media.
  • You can also use the copies for scientific purposes.
  • The new law also ensures that libraries, archives, museums and other educational institutions are allowed to evaluate texts and data.

Copy for teaching or examination purposes
You are allowed to copy several copies if you have the purpose of using them in lessons or in the exam . This law includes public and private schools, institutions for training and further education and universities. Schools that offer courses of limited duration are not included.

Conditions for educational institutions:

  • You may copy small parts or individual contributions of a work, newspaper or magazine.
  • Make sure you make copies for your own use (within the educational institution) only.
  • Do not pass on copied documents to third parties. Only teachers and participants from the same educational institution have access -to the works.
  • You should only use the copies for lessons or exams, under no circumstances for school administration or for other commercial purposes.

Copying in the community college
Inquire whether there is a contract with VG Wort for your adult education center . As a lecturer at an adult education center, you may copy up to twelve percent of a work per semester and course for teaching purposes and distribute it to the course participants only in analog form. However, you do not have the right to scan such documents and post them on the Internet.

4 TRICKS to Avoiding COPYRIGHT CLAIMS

https://youtu.be/umGyp98zu8s

Copyright protects textbooks and graphic records
Despite the loosened copyright, special regulations apply to copies from graphic records and textbooks . You may only copy such documents if an agreement has been made with the author. Copies of graphic records are only allowed if the rights holder is okay. Inquire beforehand with your school management whether and to what extent your school is involved in such arrangements .

Copyright in the profession
Since you, as an employee in a company, generally pursue commercial purposes, the copyright restrictions on copies in the company are strictly regulated.

Copyright and the corporate library
Countless companies now have a corporate library . They usually archive their own files in it or give employees the opportunity to research personal interests. Anyone who manages such a library in his company may make individual copies for scientific use for third parties.

In the age of digitization, more and more high-quality copiers and scanners like ‘ best wand scanner ‘  this scanners are able to reproduce all works true to the original but You can only use the scanners for important purposes.

 

 

Home remedies for cleaning are not always suitable

Cleaning agents often have a long list of ingredients that are not always necessary. People like to use the good, old home remedies: vinegar, soda, curd soap, baking soda and citric acid get on the dirt. However, Science laboratory experts warn that not every home remedy is really suitable.

They should quickly loosen limescale and stubborn dirt, make surfaces shine and remove every stain from the laundry: Ready-made detergents and cleaning agents promise a lot.

Do not underestimate the risk of cleaning home remedies

Old home remedies sound like a tempting alternative – and somehow familiar. Vinegar, baking soda and citric acid are even used as food, so they can give the impression of being a safe alternative to conventional cleaning agents.

But be careful: The Body Care and Detergent Association warns that some substances also occur in nature. For use in cleaning agents, however, they are usually made from other substances.

And: cleaning agents are subject to chemicals law and may have to be labeled with warning and safety instructions for use. Anyone who uses the pure substances in retail may not receive this information – and may underestimate the risks of use.

Vinegar essence is not a miracle cure
It often depends on the dosage and the field of application, whether the alternative is really good or even causes damage. Good old vinegar is an example of this.

“It is best to leave vinegar in the kitchen,” advised by the Consumer Initiative. A mixture with water disinfects the inside of the refrigerator after cleaning to avoid bacteria and germs.

For the toilet, on the other hand, it is better to use a strong vinegar cleaner, which is even better than a means with citric acid. “They don’t stick and until you’ve got something clean, the mucous membranes are seriously irritated,” said by the consumer.

Citric acid against limescale deposits
The Consumer also recommends using citric acid for limescale deposits in kettles and fittings. It is “here actually a good, gentle and food-safe means”. In contrast, the usual kitchen lemon juice concentrate is usually not strong enough.

Baking soda can promote mold
You also have to weigh up the location of the soda (sodium hydrogen carbonate, NaHCO3). It is considered a classic fat remover. Since it is a component of baking powder, the baking ingredient is also often recommended as a cleaning agent. But from the perspective of the IKW, the release agents contained in flour or starch have exactly the opposite effect: the acids cancel out the cleaning effect.

A general overview of cleaning solvents and techniques.

Do not mix detergents and household remedies

“We don’t have to do everything in the time of our grandma. A little comfort and convenience is allowed, “It was said by the specialist. However, the expert strongly advises against adding home remedies to purchased cleaners. “Each remedy should be used on its own.”

The use of any household cleaner is not good for our health. Make it a habit for you to read the labels on the package. You can also call a house cleaner like ‘ شركة نظافة بالبخار بجدة ‘ at your service to clean your home in a safest way.

How we understand each other with Communication

Human beings are essentially ” social creatures “, and advanced communication has supported the development of humankind.


While the power of the group is great, there are few things we can do alone, and we cannot live by avoiding communication with others. As long as we live a social life in modern times, we need to connect with people in some way, build relationships of trust, and cooperate with each other .

Build a relationship of trust and gain a sense of spiritual satisfaction

Through communication, we can know each other’s values ​​and ideas and build relationships of trust. Good personal and business relationships can satisfy the social needs of Maslow’s Five- Step Theory of Desire and provide a sense of spiritual fulfillment and security .

Work efficiency and productivity improvement

Much of the work needs to be done by exchanging information and communicating with various parties, cooperating with each other, and encouraging others to take action. Good communication skills help this process go smoothly and effectively, making it easier to achieve results.

Furthermore, when you realize that you are achieving results at work and contributing to the company, you will be able to satisfy higher-level needs such as approval needs and self-actualization needs.

Self-disclosure is an important point in building a relationship of trust.

Self-disclosure is to convey your thoughts, feelings, and personal information to the other party. It is not necessary to self-disclosure with people who meet for the first time or in business situations, but it will be easier to understand if you do it properly.

Respect the other person

Naturally, each person’s way of thinking and values ​​are different.
Even if the other person’s opinion is different from yours, do not deny it without thinking, but respect it.

Create an atmosphere that is easy to interact with

People who are cheerful, have a flat contact with everyone, and have stable emotions are easy to talk to. Being rich in emotions is not a bad thing, but be careful not to overexpose negative emotions such as anger and sadness.

Advanced communication has supported the development of humankind

Humans are not physically superior to other organisms (such as savanna carnivores). However, it was the acquisition of ” complex languages ​​and communication methods” that allowed humankind to move all over the world and drive many creatures to extinction in history despite their weakness, and cooperated as a group. We have each other and from you.

Other organisms, such as birds and dolphins, also communicate with each other, but human language is surprisingly flexible, which allows for complex thinking.

People can talk not only about the present, but also about the future and the past, as well as unrealistic concepts. Through such advanced thinking and communication, human beings can cooperate with “people who meet for the first time” and “people who are far away”, and by sharing a common vision, they can lead a large group. became.

Instinct to worry that you can’t do it well

Many modern people consciously or potentially feel the importance of communication because of their instincts. That is why when you feel that you are not communicating well, you feel a great deal of anxiety and anxiety or discomfort.

Communication is an important tool for building relationships of trust, fulfilling spiritually, and improving work productivity. If you are dissatisfied with the current situation, improve it to a better one as it will lead to satisfaction in your life and career and you can with How to Grow Your Business with Webinars.

 

The Beard… The Science of Hair

A well-groomed beard adorns many men and makes them look stylish without effort. For those who decided to acquire it, I will tell you about preparation, growing, leaving and other main stages – if you go through them in order, everything will work out.

Prepare – correct diet and regimen

Some men grow beards well, while others do not. Trichologists identify several reasons and factors that affect the growth of a beard: genetics, lifestyle, including diet, stress levels and bad habits, as well as hormones.

It is difficult to influence the first point, but the other two are quite feasible, and then the chances of a thick beard will seriously increase. It is worth starting a healthy lifestyle and consuming supplements such as biotin (vitamin H), fish oil and complexes that contain B vitamins and magnesium.

It is important to observe the regime of the day and rest, and sleep is considered healthy for at least seven to eight hours. During the day, it is advisable to take short breaks of 10-15 minutes, during which you can take a walk in the fresh air, do a warm-up, arrange a table tennis game with colleagues.

Start growing a beard and get itchy

It is best to start growing a beard in spring or summer: it is at this time of the year that the circulatory system works more intensively, which means that hair will grow much faster.

Before that, I recommend purchasing a beard oil like Joe´s Finest such products have a slight warming effect and increase blood flow to the hair follicles. A moisturizing or revitalizing face cream can help relieve the sensation and help the skin endure irritation.

Design a beard in the midst of its growth

After five to six weeks, the time will come when the beard will grow unevenly and the so-called “islets” will form. At this stage, it’s time to decide on the style of the beard and trim it to the chosen shape.

You can understand which beard will look harmonious by the shape of your face. A square face can be visually lengthened by making a short, rounded or triangular beard, or a goatee on the chin. A round face will visually stretch out a trapezoidal beard, wedge-shaped or a long goatee, as well as ducktail.

Continue to grow and maintain a beard

The work does not end there: the beard needs to grow more in order to look thicker. To keep it always in order, it is worth purchasing a special brush with natural bristles. It will smoothen curly hair and make it smoother, additionally it will do a light massage, increase blood circulation and stimulate new hair follicles to grow.

Maintain a tidy beard

With a beard, you will have to pay more attention to hygiene and rinse it daily with water, as well as wash it with a special shampoo once a week. It is not recommended to use hair shampoo for this: scalp and facial skin are different.

Beard shampoo does not contain aggressive surfactants that can be found in conventional shampoos, therefore it will delicately cleanse the skin of the face and hair and will not dry them out or cause irritation.

Is There A Difference In The Taste Of Coffee Depending On How It’s Made?

The streets are full of explanations on how to brew coffee, but do you know the real reason why are the taste changes depending on how you brew coffee?

There are two main ways to make coffee
There are various coffee extraction methods, but they are roughly divided into two types based on their basic principles. One is a type in which coffee powder and water used for extraction are mixed at the same time, and the other is a type in which a layer is formed with coffee powder, and water is passed through it. The former is called ” immersion/extraction “, and it may be subdivided into those that are boiled while heating directly over a fire and those that are simply soaked in water or hot water, but the extraction principle itself is the same. This includes coffee siphons, press-type coffee, and Turkish coffee. On the other hand, the latter is called ” transparent extraction “, and drip, espresso, Dutch coffee, etc. are this type. Black tea is a typical soaking extract. If you want an alternative coffee, visit mudwtr review.

The basic principle of immersion extraction
Now, from here on, it’s a bit like a high school physics exercise, but in order to understand coffee extraction, I’d like to replace it with a simplified theoretical model and think about its basic principles. Let’s start with immersion extraction, which has a relatively simple principle. As a model, after putting a certain amount of coffee powder and water (hot water) in a cup at once, take out the liquid at regular intervals while stirring, and adjust the concentration of one component (referred to as component A) in it. Consider an experiment to measure. In order to simplify the story as much as possible, we will ignore the water absorption of powder, the bias of component concentration, and the interaction between components. At the start of extraction, the entire amount of component A is present in the flour, which gradually moves into the water. One thing to keep in mind here is that no matter how long time passes, not all component A will be transferred to water 100%. In fact, during extraction, component A not only moves from flour to water but also from water to flour. This is the part that is different from the “dissolution” that dissolves salt and sugar in water, and in physical chemistry, this phenomenon is called “distribution”. This example is called “two-phase partitioning” because the component is distributed into two phases, powder, and water, or “solid-liquid partitioning” because it is a partition between solid and liquid.

Drip type is chromatography
The explanation so far may have come to the fore if you have studied analytical chemistry at university. In fact, this model is an application of the “chromatography” principle used for component separation and analysis. Even if you wondered “what’s that?”, Do you remember seeing an experiment in which ink pigments are separated with filter paper in an independent study at elementary and junior high school? Hang a strip of filter paper vertically, apply a drop of ink to a place about 3 cm from the bottom, and immerse the bottom edge of the paper in water. This experiment is called paper chromatography, and the pigment of the ink moves as the water rises due to capillarity, but it is observed that one color of ink is divided into several colors due to the difference in the degree of movement of each component.

BENEFITS OF LEARNING THROUGH VIDEOS

The following are key benefits for the teacher that result from the use of videos. We are in the computer era so video learning is getting more popular in some countries.

TEXT, GRAPHICS, ANIMATIONS AND AUDIO

Compared to the lessons on the board, where there are no digital animations, facts and connections can be better illustrated with the help of digital text, graphics and animations. Since human beings are visually predisposed and visual intelligence plays the most important role, it is much easier for many learners to record and store audiovisual content. Bain discovered that people can best capture visual and verbal content in combination.

Matheretter dispenses with the representation of a teacher and puts the content itself in the visual foreground. Thus, the learner has a direct connection to the learning content, without the audiovisual detour through a teacher.

NEW WAY OF LEARNING

Traditionally, students capture their knowledge with their own written notes during class. These ‘records’ are already included in the multimedia videos of Mathrescuers. In addition, unlike notes, the videos are not lost and can be retrieved at any time. In addition, Matheretter offers a wide range of learning programs, memorabid texts and learning graphics, along with exercise tasks and solutions that help learners practice content again. This allows for more intensive learning, which can be repeated as often as the learner wishes.

REWIND AND PAUSE

An often underestimated advantage that does not exist in the classroom is the rewinding of a video. If the content was not understood the first time, the video has the possibility of accurately repeating the module or parts of it. Videos can also be paused in case of distractions or requests. This does not interrupt the flow of learning in terms of content.

ONLINE VIDEOS FOR DIDACTIC OPTIMIZATION

Users can give a review or leave a comment to each video on video platforms like YouTube. You can also try ‘buy youtube subscribers cheap‘ to buy subscriber instantly at cheapest rates. This shows how much the learners are accepted about the content and its presentation. Incomprehensible video content or representations could thus be recognized and corrected. Not only through the work of our experts, but also through the feedback of the spectators, a high-quality didactic standard was achieved. With more than 3,000 positive reviews, Matheretter is at the forefront of modern mathematics.

LEARNING VIDEOS TO SUPPORT THE TEACHER

Through the work of our experts, high-quality videos have been created, which are demonstrably widely accepted due to their simplicity. Teachers can use one of these optimized videos to introduce a new topic. They can then discuss the content with students and solve tasks so that they can apply and consolidate the newly acquired knowledge.

During the video screening, the teacher also has the option to pause the video if students have questions about the current content. This allows the teacher to explain the missing basics separately. The video can then continue. It is also suitable for short discussions or questions directly from the teacher to his students. This is how the doctrine becomes more intense.

PROMOTING SELF-RELIANCE AMONG LEARNERS

The independence of students can be enhanced with learning videos. For example, a homework assignment can be given to deal with a specific topic, that is, watch videos, research material, and prepare a presentation that will be presented to the class the next time.

The videos also help learners to repeat learning content from the classroom at home on their own and apply it with the tutorials. Through repetition and interaction with knowledge, this is consolidated.

SHORT VIDEOS PER LESSON

Matheretter attaches great importance to the professional display of video content in a short time. A video length of 10 min is required for this. This represents a period of time for which sufficient concentration is available. In addition, Matheretter lives the principle of “quality instead of quantity”.
