The most recent Trend Connected with Extra Education - On the internet Tutoring 0SHARESShare Recent modern technology has inclined the way education is delivered to the students of today. From kindergarten all the way up to university level courses, the new pedagogy is developed to facilitate students to take learning in very easier and sophisticated way. Here is the most recent trend of taking extra education on internet tutoring: Distant Learning Education Distant Learning Education has made it possible for people to extend their boundaries with an access to best of the educational resources right from the comfort of their home. Universities offering distance learning courses, paid degree programs, online classes, free non-credit online courses are new medium to take extra education. BYOD and Flipped Classroom Bring your own device (BYOD) and flipped classroom really works with an interest to access technology outside the school classroom. The current economic slowdown has given push to this concept by saving of time and efforts. Apps World Last year lot of schools and colleges adopted iPads and tablets facilitating students to take education on-the-go. The IT industry also beckoned such electronic gadgets to make life easy for students with app-based solutions. MOOC MOOC, acronym of Massively Open Online Course is gaining its popularity with non-credit online courses. Lots of secondary students take advantages of MOOC’s. Even online tutors free use the content and adopt their lectures of professional colleagues to flip their classrooms. The courses are free taken on computer and internet. MOOC has reached nearly 200 countries in 44 languages across 4500 testing centers across the world. Multimedia Impact Educational software is trying to make learning simpler and fun filed which can be taken of its own right at home. The games are designed in a way to help students retain their knowledge and apply things that have learned in the real world. Tutors are trying to meld educational goals with multimedia games, videos, puzzles and quizzes which showed unpredictable success. Math and Science online tutoring leverage maximum from gamification. Socialization Social media has made its way in the sectors like entertainment, sports, industries and even education. Both tutors and students are continuing to take benefit from social media inside and outside classroom by creating YouTube videos, SMS marketing, classroom focused blogs and Facebook pages. Lot of English tutoring and communication programs are found available on YouTube. [starbox id=admin]

5 Strategies to Manage Introverts at Work - Introvert Whisperer

Introvert Whisperer / 5 Strategies to Manage Introverts at Work - Introvert Whisperer 5 Strategies to Manage Introverts at Work Emma Otusajo August 6, 2017 Adaptability, Communication, Leadership No responses Managing Introverts in the Workplace Your team is made up of many characters and every manager knows that although they can’t all be pleased at the same time, it is up to them to make them feel comfortable so that they can thrive in their job. Part of a manager’s job is to try different strategies to reach out to each staff member to make sure they are content, happy and given what they need to enable them to perform at their most productive. When considering whether staff have more of an extroverted or an introverted nature, this can impact on a manager’s approach to working with them and the working environment created. Happy staff means everyone gets more work done and that means the team is more productive â€" yes! The more flexible a manager can be with their approach the better â€" and staff will be grateful for these thoughtful approaches, too. So how, as a manager, can this be achieved? Learning a little something about what makes people introverted or extroverted can help. It all comes down to those brain chemicals we call adrenaline, which introverted people are highly sensitive to, as author Alen Mayer states in his book Introverts in Business: Being Quietly Successful. Extroverts, on the other hand, do not produce enough of the feel-good chemicals dopamine and adrenaline and are more likely to look for outward events that give them the uplifting feelings to raise their levels. This is why those staff who appear quieter don’t necessarily have a lack of ideas, while those who speak the most are not always right. Here are some practical suggestions to use at work to ensure more introverted staff are just as at ease and comfortable in the office as their colleagues: Let Employees Know Agenda in Advance and Write Down Ideas You’ve all been to at least one team meeting where 2 or 3 people dominate the entire conversation and you can’t get a word in. Then when your manager does ask you what you think, all you can draw is a blank because, as an introvert, ideas don’t come to you straight away. Before you know it, your colleagues are commenting about how quiet you are and your manager thinks their one quiet employee is not interested in the project. Managers can get around this by giving their team members time to think about the project in advance. Preparing an agenda ahead of time or simply letting your team members know what the topics will be will help and allow them time to come up with their own ideas, ready for the meeting. Praise and Criticism   When it comes to praising staff, a manager may think it’s great for everyone to be congratulated and recognised at the next team meeting by way of an official announcement, but get ready: Not everyone will be. While not all, many introverted staff will feel overwhelmed by suddenly being in the spotlight and overwhelmed by the spontaneous liveliness that takes place. Managers could try letting their staff know in advance that they are going to be mentioned at the next team meeting so that at least the employee has a chance to turn down the offer. An extrovert may appreciate praise from their manager when it is given in the presence of a team dinner or meeting. Introverts will much prefer and appreciate being praised on more of a one-to-one basis to let them know how much they’re valued. This is the same for giving constructive criticism â€" do it at the next appraisal or review meeting to give your introverted staff member time to think about it and respond. Communication in the Workplace   In an environment where there is pressure to get things done and to do tasks quickly, managers can often expect answers to their questions or demands to be given on tap. This is especially pressurising when a manager stands over your desk expecting you to find what they need or answer them straight away. When asking a question, a manager can give their staff time to run through their thoughts briefly or to find what it is you need, so that they don’t feel any undue pressure. Wait for them to finish speaking when they’re in the flow (which is worth it when they do) â€" interrupting them will throw them off track and they may not be able to finish making their point, or won’t feel that they have been listened to. Different Workspaces in Your Environment   With the introduction of open plan offices and hot desking, while for some it was an opportunity to interact with more people during the day and be more sociable â€" for the more introverted staff, it was more of a nightmare. For the introverts among us, entering an open plan office means more people looking up at you, as if you’re walking down a catwalk putting on a show you really don’t want to do. Even if you do seek out the comfort of a familiar face, any conversation you have carries out across the room! Managers, organise workspaces to allow for some small, more secluded spaces so that employees can have at least semi-private conversations and not feel like they are no show by anyone and everyone. This can consist of booths and small, partitioned offices that make staff feel like they’re not so much in the spotlight. Seeing Everyone’s Strengths   While it is important to enable time for introverted staff to have some quiet in the office or by themselves, it can be equally as important to plan team training or activities that bring all your colleagues together. Learning about one another’s differences and getting to each other on a more personal level is always going to be a positive when it enables staff to understand each other’s strengths, shown through the activities planned. An activity to build a raft together? That quiet girl who sits in the corner knows how to tie rope together so that the raft can be strong. Tasks outside of the office can also remind introverts to see the strengths of their extroverted colleagues â€" but do give them plenty of notice of the get-together first.

Highlights Of Contemporary And Modern Art

Highlights Of Contemporary And Modern Art Discover Art Movements ChaptersThe Highlights Of Pop ArtThe Highlights Of SurrealismThe Highlights Of CubismThe Highlights Of ImpressionismThe Highlights Of ExpressionismThe Highlights Of BaroqueArt movements have always been full of change, expression and often communicate the way that people perceive the world around them. Here we present you with 6 different artistic styles and give you some highlights of the Artistic movements for you to understand them.Art movements have always been full of change and expression. Photo Source: Unsplashdecided to pursue his art.As well as being an expressionist, Kandinsky is also the pioneer of the abstract art movement. He interrelated colour and form to create an experience which evoked all emotions. He wanted to communicate spirituality through art and inspire an aesthetic experience like visual poetry. Music was greatly incorporated into his process, and he worked to replicate the freedom of sound within his paintings.Top artworks: The Blue Rider (1903), The blue m ountain (1908/9), Composition IV (1911)Birthplace: RussiaLifeline: 1866 - 1944Art Style: Expressionism and abstract expressionismInspired by: Post-impressionists,Art Forms: PaintingPopular Expressionist Work: Vase With Twelve SunflowersVan Gogh's paintings of sunflowers of some of the most famous painting in his collection. Painted in the south of France Van Gogh painted a series of 5 images of sunflowers in a vase. In the image, if you look closely, you might notice that he only used a few colours to paint the entire picture, namely 3 tones of yellow. He wanted to demonstrate it was possible to paint an image with only a single colour.He painted the series to communicate gratitude, happiness and hope. The colour that he used was a new and none permanent yellow colour which is why today the painting has faded from their former glory. Van Gogh used these impermanent colours on purpose and is quoted as saying paintings fade like flowers. The images have started boldly with bright, vib rant colour and through the centuries have slowly faded and muted in their vibrancy.The Highlights Of BaroqueBegan In 1600Baroque artists like Caravaggio were commissioned by the church and religious institutions to create extravagant artwork.  Although not exclusively, the work highlighted the power of the Catholic church. Paintings, buildings, music, literature and dance all expressed the style.Baroque Artist: Van DyckSir Anthony van Dyck was born in Antwerp, his artistic career started early with his first painting being at age 17. By age 20 he was already in the service of the king of England where he became one of the leading painters at court. Passionate about his craft, he travelled to Italy and the Netherlands for an extended period to gain more inspiration and experience. By the time he returned to English court, he was well renowned and successful. He is well known for his portraits of King Charles I.Top Artworks: Charles I at the hunt, Charles I in three positions, Cupid and psycheBirthplace: Antwerp, BelgiumLifeline: 1599 - 1641Art Style: Baroque (European art)Art Forms: PaintingPopular Baroque Work: Judith Slaying HolofernesThis painting is of a heroic woman called Judith, by Artemisia Gentileschi (one of a small number of Female artists). The figures are bursting out of the darkness. Beautifully highlighted figures fill the foreground in a luminous but dim light. The story is that the heroic woman Judith hatched a plan to catch the eye of the general, Holofernes who leads the Assyrian army. The same army which has laid siege to her town Bethulia which is about to lose in battle. Judith’s plan works perfectly, and Holofernes gets drunk and falls asleep. Judith’s maid helps in the murder as Holofernes tries to fight them off. At which point Judith beheads him with his own sword. The limbs of the women and the general lead the eye directly to the beheading. Judith’s hand trusses Holofernes’ hair and turn him to face us. He is powerless to d o anything but look on and await his fate. The contrast of colour and the play with light really brings our focus to the main point of action.Pop artists wanted to connect art to their experience. Surrealists wanted to break down the barriers of the mind. Cubists want to look at things differently. Expressionists wanted to express their emotions on the canvas. Impressionists want to get out of the studio and make art of whatever caught their eye. The baroque was lead by religion to establish power. Which do you like best?

Algebra Lessons

Algebra Lessons We know Algebra is a branch of mathematics. We know Algebra mostly related to numbers and variables. In Algebra we have a number of lessons. Those are 1. Algebra Basics In this we have Equation Basics, Proportion Basics and Word problem Basics. 2. Simplifying Simplifying introduction, simplifying multiple signs, combining like terms, Multiplication. 3. Substitution 4. Factoring 5. Equations Advanced solving Example 1: Solve the equation x^2 11x + 10 = 0 Solution: The given equation isx^2 11x + 10 = 0 We know, this is a quadratic equation in terms of x To solve this, we need to write the middle term as two parts. We can write the middle term 11x into two parts, those are - 10 x - x. Since the addition of -10x and x is 11x and product of 10x and x is 10 x^2 We can write the given equation as, x^2 10x - x + 10 = 0 x (x 10) 1 (x 10) = 0 (x 10) (x 1) = 0 X = 10 and 1. Example 2: Solve the equation x^2 5x + 6 = 0 Solution: The given equation is x^2 5x + 6 = 0 We know, this is a quadratic equation in terms of x To solve this, we need to write the middle term as two parts. We can write the middle term 5x into two parts, those are - 3x 2x. We can write the given equation as, x^2 3x - 2x + 6 = 0 x (x 3) 2 (x 3) = 0 (x 3) (x 2) = 0 X = 3 and 2.

In Hatha classes, yoga poses are often slow and held for a few breaths before moving on.Ashtanga YogaAshtanga yoga is perfect for yogis who love following a set workout routine. Although the movements are smooth and there is a focus on breathing, you’ll certainly work up a sweat by repeating the same sequence of movements!Vinyasa YogaVinyasa is similar to Ashtanga in its intensity and the way that it focuses on the smoothness of the transitions between poses, however, there is no fixed routine â€" perfect for those who enjoy a bit of variety! Vinyasa classes are often lively, too, as teachers play upbeat music to accompany the class.Yin YogaAt the opposite end of the spectrum to Vinyasa and Ashtanga yoga, Yin yoga is focused on the meditative aspects of yoga and each gentle pose is held for minutes at a time. If you need to find your zen, his variety of yo ga is the one for you.Iyengar YogaIyengar yoga classes challenge you to pay close attention to the alignment of your body. Like in Yin yoga, poses are held, and you’ll use several pieces of yoga equipment to help you get the most out of each pose.Simple Yoga Poses for Back PainThe restorative and strengthening properties of yoga make it a popular form of exercise for people who suffer from all kinds of back pain.Not only can regular yoga practice release tension from your muscles and joints, but it can also contribute to an improved posture and prevent further back complaints.So, what are the most effective poses when doing yoga for back pain?Downward-Facing DogIf you’re a complete newbie to yoga, downward-facing-dog is likely one of the first poses you will learn.Make a V-shape with your body, keeping your hands and feet planted and your heels down. Relax, take several deep breaths while you hold the pose and feel the stretch in your upper and lower back.Downward dog is a funda mental yoga pose ¦ source: Pixabay - AndiPThis pose is great for elongating the spine and strengthening the lower back muscles.Spinal TwistThe seated spinal twist is good for people looking for relief for back stiffness.Sitting on the floor with your legs straight in front of you, bend one knee and put your foot flat on the ground. Support yourself with the arm on the same side as the bent leg, and put the elbow of your other arm on the outside of your bent knee.Cross your foot over for a more challenging stretch ¦ source: Pixabay - evitaochelThere are many variations to the spinal twist with a range of difficulties.SphinxSphinx pose is not just great for preventing lower back pain, but it is also incredibly simple to do.Lay on your front with your legs relaxed behind you. Next, support your upper body by bringing your elbows underneath your shoulders with your forearms out in front of you. As you inhale, press your chest outwards, and relax as you exhale. You should feel a stretc h in your abdominal muscles and your spine.The sphinx pose is known to strengthen the spine and tone other muscle groups ¦ source: World Peace Yoga SchoolCat/CowThe cat/cow movement is a combination of two yoga poses which stretches the back in a dynamic way whilst improving mobility. This is another very simple pose which is popular as a warm-up transition.Begin in a tabletop, with your hands and knees shoulder and hip-width apart respectively. Start with the cow pose by arching your back towards the ceiling whilst pushing your hands and feet into the floor as you drop your head down. To transition to the cat, arch your back the opposite way whilst moving your head up and looking forward.BowThe bow pose is quite an intense exercise, so you may wish to seek advice from a yoga instructor before attempting it.Begin by laying on your front, then bend your knees and reach back with your arms to grasp your feet.

Everything You Need to Know about Magnetic Fields.

Everything You Need to Know about Magnetic Fields. An Introduction to Magnetism. ChaptersWhat is Magnetism?Different Types of Magnets â€" and Different Types of Magnetism.Is the Earth Magnetic?Magnets are one of the most common tools in our day to day lives, popping up in all sorts of contexts and places. Look at the door of your fridge â€" which is held tight by magnetism. Think about your headphones or computer speakers; magnets power them. Or play with your parents’ car window; that too is made possible by magnetic materials.Magnets are, quite literally, everywhere. Electricity and magnetism â€" and the science behind the magnetic field â€" are some of the most useful scientific tools we have. So much stuff would just not work if we didn’t have them.Yet, given the ubiquity of magnetic material and magnetic tools, we sort of take this phenomenon for granted. But if you stop and think about it, isn’t magnetism amazing? Isn’t it incredible that a piece of metal can move another through some invisible force? Don’t you think that the science of this stran ge process is actually pretty cool?No? Well, maybe that’s because you don’t know enough about it. So, with the intention of persuading you that magnetic force is actually one of the most interesting things in nature, let’s take a look at what it is all about.We’d be surprised if you didn’t agree by the end of this article. You can check out our full guide to magnetism and electromagnetism too!

Discover all our tutorsWhat is Magnetism?Magnetism is the force by which magnetic materials attract and reject other magnetic materials. This is the most common way in which you see magnetism in action in everyday life, when bits of metal are pulled towards other bits of metal.This, incidentally, is what makes magnets so interesting â€" and so useful in day-to-day life. Magnetic force is a non-contact force, meaning that magnetic materials don’t need to be touching for their effect to be felt.Yet, this is not just magic â€" although it may once upon a time have been believed to be such. Rather, the forces that these materials enact are the result of a process that happens at a level too small for us to see with our eyes. At this level, everything is in motion.And what creates the force that we witness is the result of two phenomena at that level. The first being the ‘magnetic moment’ of a given element and its particles â€" and the other being an electric current.Magnetic Mome nts and Electrons.What is happening at a much smaller level is all about electrons, one of the subatomic parts of a material.These electrons move, or rotate, around the nucleus of the atom. And each one has a different charge â€" generally either positive or negative. Normally, the electric charge or spins of these electrons are balanced â€" meaning that the number of positive electrons is equal to the number of negative electrons.Nature tends to like stability and stasis and, in this context, this means that nonmagnetic materials are the norm, due to the fact that with the equality of positive and negative electrons, the magnetic moment of these electrons is cancelled out. This is helpful as, otherwise, everything in the universe might be magnetic â€" which wouldn’t be super convenient.Sometimes, the electrons in a material aren’t balanced â€" this is true. However, more often than not in such cases, their magnetic charge is not aligned â€" something that is a prerequisite for magnetism proper.Magnetism in the way that we recognise â€" with the two magnetic poles of a magnet â€" occurs when the electrons’ magnetic moments are all aligned, i.e. pointing in the same direction. Only at this point will a material produce a magnetic field strong enough to be relevant.Find a maths physics tutor here.Electricity and Magnetism.As we said, there are two sources of magnetism. The first is the magnetic moment of the given electrons and their alignment. The second is an electric current.Electric currents produce magnetism because electricity is the flowing of electrons through a material. With this, you have a phenomenon in which all the electrons become necessarily aligned through their motion â€" and this motion gives the electric wire a positive charge and a negative charge.Electromagnets.You’ll have probably heard of an electromagnet â€" or of electromagnetism in general. These are super-strong magnets that are powered by electricity. Along with the majority of things that are powered by electricity, you can turn these on and off too â€" which makes them quite convenient for industry.If you take a magnetic substance and wrap a coil of wire around it â€" with an electric charge passing through it â€" you will find that the resulting magnet is really very strong indeed. The whole coil becomes magnetized in this way, with the electrons from the wire producing a magnetic field that attracts into the centre of the coil.As soon as you switch off the electricity, the coil is no longer magnetic.This is a crucial part of electromagnetism. Electromagnets produce a strong magnetic field.What is a Magnetic Field?Magnets attract and repel other things that are susceptible to the force of magnetism. We know this.Yet, the important thing is what happens between the two materials that are magnetic. This is the magnetic field â€" an invisible field of force which is essentially the arrangement of the electrons in the surrounding area.You’ll have seen the diagrams of magnetic fields before. And what you’ll recognise is the dipolar nature of magnets â€" the fact that magnets have both a north pole and a south pole â€" as well as the magnetic field lines which we tend to draw between the dipoles.These lines represent the magnetic flux that emerge from the north pole and enter the south. The closer together the lines, the stronger the magnetization. These lines never ever cross, by the way.Iron Filings.One of the best ways to see a magnetic field for real is through the use of iron filings.Get yourself a bar magnet and a hand ful of teeny-tiny bits of metal â€" iron filings, essentially the dust of iron.Drop the iron onto the magnet and watch the magnetic field appear, with all the different lines of force included. It’s quite impressive, actually.Different Types of Magnets â€" and Different Types of Magnetism.You probably have the impression already that not all magnets are the same. Given that we know that there is such a thing as electromagnetic force, as well as ‘normal’ magnets, we can pretty much assume that there are more types of magnet too. We’ve already mentioned bar magnets, for example.Scientists love to characterise things â€" and you need to know the categories that they create.Diamagnetism.Let’s start with diamagnetism. This is the type of magnetism which everything has all of the time. However, it is not particularly ‘magnetic’ in the sense with which we are conventionally familiar.Rather, in a material that is ‘diamagnetic’, there are no unpaired electrons at all. And, in the presence of paramagnetic or ferromagnetic substances, the diagmagnetism is overwhelmed.Paramagnetism.Paramagnetic materials are those that are weakly attracted to any magnetic field to which they are exposed. The majority of chemical compounds are paramagnetic, because they usually have electrons that are not paired (see above). This means that even elements like oxygen are actually paramagnetic â€" something of which maybe most people are unaware.In paramagnetic substances, the unpaired electrons align to the magnetic field, giving the substance an overall charge.Ferromagnetic Materials.Ferromagnetic materials are those that we conventionally recognise as magnetic.These materials have unpaired electrons too. However, unlike in paramagnetic materials, the electrons in ferromagnetic materials tend to line up spontaneously. This means that they don’t need an external magnetic field in order to become magnetic.These materials are the commonly magnetic ones â€" such as iron (he nce the name ‘ferro’), nickel, and cobalt. Iron is a ferromagnetic materialTemporary Magnets and Permanent Magnets.These two terms â€" temporary and permanents magnets â€" are fairly common in conversations about magnetism. And the difference is probably fairly obvious.Permanent magnets are those that are ferromagnetic. These retain their magnetic potential even after they are not in the presence of an external magnetic field.Temporary magnets are those paramagnetic substances that require an external magnetic force. These things are like paperclips â€" objects that react to magnetism but are not themselves magnetic.By the way, heating a ferromagnetic substance messes with its magnetic potential. The energy of heat creates much greater atomic volatility â€" meaning that the electrons cannot remain aligned.Find out about transformers, one of the most important magnetic technologies!Is the Earth Magnetic?You know that the Earth has a magnetic field, right? That’s the reason why we give magnets the characteristics of having a ‘north’ pole and a ‘south’ one.The whole of the globe is magnetic â€" which is the reason why compasses work. If you were to pick a handful of mud, it wouldn’t be magnetic, but the size of the earth produces the biggest magnetic field on the planet.Why does it do this? No-one is quite sure. However, scientists think that it is because of convection currents in the Earth’s core â€" which are primarily made of iron and nickel. And it's that that produces the northern lights.Ever heard of electromagnetic induction? Find out about it here. The Northern Lights are the result of the Earth's magnetic field

Critical Reasoning Question 14-Packaging Company - Private Tutoring

Critical Reasoning Question 14-Packaging Company BobbiM Feb 16, 2014 World War II had a profound effect on the growth of nascent businesses.  The Acme Packaging Company netted only $10,000 in the year before the war.  By 1948 it was earning almost 10 times that figure. The argument above depends upon which of the following assumptions? A.  Acmes growth rate is representative of other nascent businesses. B.  An annual profit of $10,000 is not especially high. C.  Wars inevitably stimulate a nations economy. D.  Rapid growth for nascent businesses is especially desirable. E.  Acme is not characterized by responsible, far-sighted managers. Think you know the answer? The correct answer is A. The author uses the single case of Acme to conclude that the war profoundly affected nascent businesses.  This assumes that Acmes growth rate is typical, or representative, of such businesses (A); otherwise, why hold it up as an example? As for (B), the author neednt assume that $10,000 isnt much of a profit.  Maybe he thinks it started out high and got even higher.  (C), which brings up other wars, is beyond the scope-the argument concerns World War II, period.  (D)s tricky, but its not assumed.  Notice that the author claims only that World War II had a profound, not salutary, effect on nascent businesses, so we dont know just how he feels about rapid growth rates.  As for (E), the author neednt assume Acmes managers had nothing to do with the companys success, just that the was also had an effect-and a marked one.
