Tutoring a Child: The Advantages of Using the Internet to Find a Tutor

Tutoring a Child: The Advantages of Using the Internet to Find a TutorYou might be able to find a tutor in your local area, but if you have limited funds and cannot afford to pay for his tuition you might consider using the internet to find someone who will work with you and help you complete the tutoring. You can save money by finding the tutors that are available online who can offer their services at a cheaper rate and provide quality tuition, they can also offer you their materials for free in order to get your business.Tutors will also offer you a variety of packages to suit your budget, with packages for all levels, young adults, seniors, children and all other ages. Some of these services are also available on the internet, others require that you are located in the area that the tutor is located in, and so you need to pay him a visit to set up a meeting, before you start to work with them.Make sure that the tutor you are looking for has completed some form of education or has a certificate of completion. You will also need to check the qualifications and references of the tutor in order to determine if he or she is one who you can trust with your child, or if you feel you are comfortable having someone who has never taught before taking your child's hand.You may wish to meet the tutor in person, or if this is not possible you can often see his work at different tutoring sites. There are many sites on the internet that offer these types of services. Make sure that you read the fine print in the tutoring contract so that you know exactly what is going to happen in terms of tuition payment, and what should you expect as a result of that tutoring.Even though it may seem like an awful lot of money to pay for a tutor, as a parent you have to think about the fact that you are putting yourself in danger of having a child who is unable to concentrate in school. When you choose a tutor you will be more likely to get the attention of your child when they need it, and this is likely to result in better grades, because of their improved attention span.You can also check out a couple of online websites that offer tutoring at a cheaper price, usually under $100 per hour, which is a very reasonable amount of time tuition payment, and is far less than most local tutors charge. It may also be possible to find a tutor who is willing to come to your home and work with your child, for a price that will include the tuition payment, and the time that your child spends working with them at your home.There are many parents who have been impressed with the price and quality of tutoring that they have received from the tutor, especially if they have been able to pay less time tuition payment than the average family would pay for that kind of service. So if you are someone who is unsure whether or not you can afford the tutoring, you might want to think about whether or not this may be something that you might consider, as it could mean a big difference in y our child's success at school.

Tutoring Jobs - Are You Sure That The Tutoring Job You Are Looking At Is Right For You?

Tutoring Jobs - Are You Sure That The Tutoring Job You Are Looking At Is Right For You?The Princeton Review reviews the pay and benefits of tutoring managers and has done so for over twenty years. It has evaluated the information available about tutoring jobs and has found that the biggest payoffs come from at-home tutoring and from tutoring with an independent tutor.Tutoring managers are responsible for a myriad of tasks including scheduling appointments, marketing their services, writing out application requirements, selecting and submitting student applications, tracking attendance, creating standardized tests, setting up meetings, and assigning grading options. It's not easy to be a tutor, but the perks do come. One of the top perks is that there is no long-term commitment required to start earning money as a tutor, unless you choose to work part-time.The Princeton Review also reviews the benefits of tutoring. Many benefits come with the position, but only the most reputable, bes t-known schools offer comprehensive benefits. For example, all tutors have access to a portfolio of their work, which is available to all applicants, at no cost. There are also tutoring clubs and support groups, so that tutors can meet other tutors in their own field.By providing their own files, parents and students save money and also know exactly how much they're paying for each tutor hour, or through the purchase of each lesson. In addition, because the courses are available to all students, at no cost, there is a far more affordable, tailored tutor environment for students who need professional tutoring.The main benefit is the financial one, because after taxes, it's possible to earn up to six figures on an hourly basis. Some tutors earn ten figures! All of this comes after a year of paying your dues and filling out yearly reports to certify that you earned the minimum. So the cost per tutor hour isminimal, and the average tutor make a good living and are free from doing anythi ng that he or she doesn't enjoy.One good reason for hiring a tutor is because of the benefit of having somebody around that will support you during test time. This can be a friend or relative, and may even be someone who works for the school you are attending. It may not be possible to pay for somebody to stay with you while you take tests, so having somebody who is a member of the tutoring community in your corner, can help immensely. There are also tax deductions from your taxes that accrue, allowing you to end up saving more money on your taxes than if you weren't working at all.Ultimately, the Princeton Review, and finds that the big payoff comes from the benefits that come with being a tutor. The rewards are immense and can give you a better income and an enriched life.

Square Root Formula

Square Root Formula Square root of a number or an expression is represented by a radical sign and the square root of a number means that the number is raised to an exponent of 1/2. In order to find the square root of a number, we have to find the number which when multiplied by itself gives the given number. Perfect squares are the numbers which give a perfect number when taken their square root. The square root of a number which is not a perfect square can be calculated by simplification. Example 1: What is the square root of 64? Square root of 64 can be also represented with the radical sign as 64. In order to find its value, we need to find the numbers which when multiplied by itself gives 64. 8 * 8 = 64 and we also have -8 * -8= 64. This implies that 8 multiplied by itself or -8 multiplied by itself gives 64 as the answer and 64 is the perfect square. Hence, square root of 64, which implies 64 = 8. Example 2: Simplify the square root of 48? Here 48 is not a perfect square since there is no number which can multiply by itself to give 48. So now prime factorization of 48 gives== 48 = 2 * 2 * 2 * 2 * 3. This implies: 48 = (2 * 2 * 2 * 2 * 3) Now we can pull out the numbers which are repeating twice inside== 2 * 2 * 3. Hence 48 = 43. Therefore the simplified form of 48 = 43.

Binary Decimal Converter

Binary Decimal Converter Binary numbers are numbers different from the decimal numbers. In the binary number system, any number is represented with the combination of 1 and 0 only. However the number system which we generally use is the decimal number system and here we use all the digits starting from 0 to 9. The binary decimal converter is the method in which any binary number can be converted to its decimal number. Example 1: Convert the given binary number into decimal number 11001. To convert the given binary number to a decimal number, we can use the method known as the Doubling method. Start from the binary number on the left (0 * 2) + 1 = 1 Now multiply the previous answer 1 with 2 and add the binary number (1 * 2) + 1 = 3 (3 * 2) + 0 = 6 (6 * 2) + 0 = 12 (12* 2) + 1 = 25 Hence the binary number 11001 is equal to the decimal number which is 25. Example 2: Convert the given binary number into decimal number 101011. Start from the binary number on the left, and multiply the previous answer 1 with 2 and add the binary number. (0 * 2) + 1 = 1 (1 * 2) + 0 = 2 (2 * 2) + 1 = 5 (5 * 2) + 0 = 10 (10* 2) + 1 = 21 (21* 2) + 1 = 43 Hence the binary number 101011 is equal to the decimal number which is 43(base10).

Why Is It Important To Develop Emotional Intelligence Skills

Why Is It Important To Develop Emotional Intelligence Skills Why is the Emotion Quotient Relevant? ChaptersWhat is the Emotional Quotient?How to Become Emotionally IntelligentAre Emotional and Social Intelligence Important?How to Develop Personal Intelligence SkillsOnline Help for Self-AwarenessIf you’ve never heard of Goleman’s seminal book Emotional Intelligence: Why It Can Matter More Than IQ, this guide is for you. Many of us tend to think of our emotions as something that is outside of our self-control and self-regulation abilities. In fact, up until recently, empathetic or emotional people tended to be portrayed in popular media either as offbeat, bohemian souls or as emotionally chaotic and troubled.While films and novels seem to have caught up with the fact that self-awareness and empathy are traits we all possess, and constantly have to work on, many still don’t consider self-management and interpersonal skills as on par with those that come with becoming intelligent in particular fields.Emotional intelligence, however, is becoming increasingly more important to all aspects of life, improving everything from job performance to social skills. In fact, there are articles produced every week not only on the importance of gaining interpersonal skills, but also the best ways to teach yourself and others the art of managing emotions and moods. If you’re still not sure how developing emotional intelligence is relevant to your life, we suggest starting by understanding what exactly emotional learning is and why it is such an important skill to learn.

While the concept of measuring intelligence on the basis of characteristics other than skills based on logic and reasoning has been criticized by many in th e scientific community, those same scientists do tend to agree that there is a need and demand for a more holistic approach to defining intelligence.Emotional intelligence isn't a new concept, but it was brought into the mainstream by the help of journalist Daniel Goleman. Goleman's bestseller  Emotional Intelligence brought social competence and emotional awareness to the forefront of the conversation revolving intelligence. More than twenty years after his publication, the importance of measuring emotions and empathy with their own intelligence test hasn't been lost on the psychology and self-help industry.If you're interested in emotional intelligence, you should understand that the concept deals with a human's capability to understand, process, and react to their own emotions and the emotions of others. These abilities deal with being able to empathize, be self-aware and be able to self-report one's own emotions. The majority of the work behind this subject has been developed or iginally by psychologists Salovey, Mayer and Caruso. If you're interested in reading some of the history behind emotional intelligence and an emotional intelligence test such as the MSCEIT, start by reading some of their published works.How to Become Emotionally IntelligentEveryone from gardeners to salespeople all have one thing in common: they all have to deal with having emotions. Whether you're interested in building up the rapport between you and your boss, want to develop your soft skills or want to improve the relationships you have with your family, becoming more emotionally intelligent may be in your best interest.Some of the tips that you can take advantage of to kick-off your journey into emotional intelligence are:reading more about the subject through blogs and websiteslistening to knew podcasts about mental health and well beingtrying out new health food recipeslearning a new skill such as gardening or crochetingEmotional intelligence can be a difficult field to naviga te.

If you want to learn more about trust and leadership, read more about EQNeedless to say, attempting to distill emotional intelligence and general intelligence into specific definitions will, by their nature, become outdated or incomplete over time as society’s views and tastes shifts. So why is having a high emotional intelligence important? The first way we can view the importance of emotional intelligence is through the ability of correctly perceiving the emotions of oneself and others.Salovey and Mayer posit that recognizing “emotional patterns” are vital to the way we reason through problems. Fore example, correctly identifying and processing someone’s disappointment or happiness is a vital mental step in determining what actions to react with. Not being able to judge someone else’s emotions over particular topics or body movements can be detrimental not only in social settings but in professional settings as well.   Social awareness is something that many people have t o consistently work on in order to improve how well they interact with strangers, uber successful people, family and more.The significance of controlling your facial expressions and body language is easy to understand - you don’t need a Harvard Business Review article to tell you that mastering social interactions can lead to personal and professional success. However, emotional intelligence can be extremely important for your mental health as well.Being able to identify negative emotions and process them in healthy and productive ways are tasks that many adults struggle with, sometimes for a lifetime. Developing an emotional literacy with yourself, being able to keep inventory of your emotional catalogue, can improve your physical health, help you achieve your goals and improve the relationship you have with yourself and others.Learn more about the emotional intelligence with this guide to EQ basics!

Life Is All About Change - Introvert Whisperer

Introvert Whisperer / Life Is All About Change - Introvert Whisperer Life Is All About Change I’m a bit sentimental today. Some of you may know or realize that when I started out as a coach, my website and business name was Next Chapter New Life. When I launched Introvert Whisperer over a year ago, I was unclear what to do with that website. Because I wasn’t clear, I kept it going and continued to post content to it. I decided to “end-of-life” the website, thus closing that chapter in my life. That’s why I’m waxing nostalgic. It won’t impact anything you typically see from me. Because my roots are in change, I have to use this as an illustration for you on how we work in making change and the emotional reaction to change called transition. The first phase of transition is an ending. Something has to come to an end and for me, the end started last year as I ramped up Introvert Whisperer. During the end phase, you begin to disengage and begin to lose identification with what you are ending. I was identifying less with Next Chapter and more with Introvert Whisperer. The next phase is what I called confusion; Because it is largely a period where you feel unshaped by purpose. With my Next Chapter website/persona, that period of confusion has lasted a year.     I wasn’t clear what to do with it so rather than pulling the plug or redefining it, I decided my clarity would eventually come as I spent more time defining myself with Introvert Whisperer. I’ll note that we all move through our transition phases at different rates. For me, I felt that there would come a day where the answer of what to do would eventually arrive. It also let me come to grips with ending something I was very emotionally invested in. The last phase is beginnings. Introvert Whisperer to a large degree was the beginning and with this phase you have a new identity or direction. It’s an energetic phase as you are further touching into new territory. I’ll note for you that while these three parts of transition are called phases, they occur at the same time. They occur in different proportions throughout the change but we shift through them daily. Because of the overlapping nature of the phases, we also experience mixed emotions and can often confuse these mixed emotions for making a wrong decision. You can feel happy and sad at the same time. It’s a huge reason so many people avoid change because its not that comfortable. Transition = Endings-Confusion-Beginnings. You will always go through them with any change. Just know that when you’re at a low point or anxiety-ridden â€" you’re normal! You will get through it. So, bye-bye Next Chapter New Life.

wave

wave Wave It will be amazing to know that there is not a single moment in our daily life when we do not encounter a wave. Let it be in the form of light waves, sound waves, water waves, radio waves etc, waves are always a part of our life. Considering a slinky as an example after we stretch a slinky from end to end, it naturally comes back to its original equilibrium rest position. So here we can notice that a wave passes through the slinky as a disturbance is generated due to our stretching it. This disturbance passes through the slinky and after some time gets it back to its original state of rest. What is a Wave? A wave is usually described as the disturbance that passes through a medium from one location to another location. A wave medium is a substance or material that transports the wave from one location to another location. Here it is to be noted that the medium simply carries the wave from one point to different locations, but the medium does not play any role in creating or generating a wave. For instance, we can notice the waves in an ocean. The medium through which the water waves travel in an ocean is the ocean water. For a sound wave, the medium through which the sound wave travels is the air present in the room. A single disturbance that passes through a medium from one point to another point is known as the Pulse. However, if the disturbance is continuously repeated causing it to become a periodic disturbance that moves from one location to another location, then that disturbance is described as the Wave. Interaction of Particles in a Wave: Medium is a collection of particles that have the ability to interact with each other. Due to the interactions between a particle and its adjacent particle, the disturbance travels through the medium. The constant push or pull between the neighboring particles allows the disturbance to spread across the medium. However, it is to be noted that the individual particles of the medium are only temporarily displaced from their original rest position. Eventually every particle carrying the wave return to their original position. Therefore, we can say that a wave transports energy from one location to another location but it does not transport matter. Due to this reason we can see that in an ocean waves are seen to move through the water, however the water always returns back to its rest position. Only the energy is being transported through the medium, but the water molecules are not transported. Therefore, a wave can also be described as the disturbance that travels through a medium (with the help of particle interaction) carrying energy from the source to another location, without transporting matter. Types of Waves: Waves can be classified into 2 types based on the ability to transmit their energy even in vacuum or only through a medium. i) Mechanical Waves ii) Electromagnetic Waves 1)Mechanical Waves: The waves that travel through a medium that is a solid or a liquid or a gas (at a speed which depends on the elastic properties of the medium) are known as the Mechanical waves. Based on the direction of the individual particles of the medium to the direction of the travelling wave, these mechanical waves are commonly classified into 2 types. a) Transverse Waves b) Longitudinal Waves a)Transverse Waves: The wave in which the particles of the medium move in a direction that is perpendicular to the direction in which the wave travels, is known as the Transverse wave. For instance, if the energy of the wave is transported from left to right, then the individual particles in the medium are displaced upwards and downwards in a transverse wave. Transverse waves are always characterized by the property that the particle motion is perpendicular to the wave motion. In order for the particles in a transverse wave to move perpendicular to the wave direction, they must be able to strongly exert a pull on its neighboring particle. Due to this reason, transverse waves require a rigid medium to pass through and hence these waves can usually pass through solids only. b)Longitudinal Waves: The wave in which the particles of the medium move in a direction that is parallel to the direction in which the wave moves, is known as the longitudinal wave. For instance, if the energy is transported from left to right, then the individual particles of the medium will be displaced leftwards and rightwards in a longitudinal wave. Longitudinal waves are always characterized by the property that the particle motion is parallel to the wave motion. Unlike transverse waves, longitudinal waves can pass through solids, liquids and gases. A sound wave passing through air from the speakers mouth to the listeners ear is an example of a longitudinal wave. Seismologists have discovered that during an earthquake, the waves produced were both transverse and longitudinal waves as they could pass through the solid structures of the Earth, however only longitudinal waves were able to pass through the core of the Earth. Geologists therefore believe that the core of the Earth contains a liquid (mostly molten iron). Surface Waves: These are another kind of waves that are can be either elastic or seismic waves (seismic waves are the waves generated during an earthquake or an explosion). The motion of these particles decreases as we step away from the surface. In seismology (study of earthquakes), there are different types of surface waves and they are usually either Love waves (they have transverse motion) or Rayleigh waves (they have both transverse and longitudinal motion). The waves on the surface of the oceans and seas are also examples of surface waves. 2) Electromagnetic waves: The waves that are capable of transmitting the energy even through vacuum (or empty space) are known as the Electromagnetic waves. This implies that these waves do not need a medium to transport energy from one location to another location. These waves are produced due to the oscillation of the electric and magnetic fields. It is interesting to note that we use electromagnetic waves everywhere in our daily life. From the point of listening to a radio, watching television, or cooking lunch in a microwave oven, we are using electromagnetic waves every time. The radio waves, microwaves, ultra-violet rays, X-rays etc are all examples of Electromagnetic waves. We need electromagnetic waves for our very existence as the life-giving beautiful light rays emanating from the Sun that travel all through the outer space and reach Earth are also electromagnetic waves. Crests and Troughs of a Transverse Wave: In a transverse wave, since the particle motion is perpendicular to the wave motion, we can observe the maximum displacement reached by the particles from their original position. When a string initially at rest is disturbed, then we can observe that the particles of the string vibrate upwards and downwards, reaching maximum upward/downward displacement. In a medium, the crest of a wave is the point that exhibits maximum amount of upward or positive displacement from the original rest or equilibrium position. In a medium, the trough of a wave is the point that exhibits maximum amount of downward or negative displacement from the original rest or equilibrium position. Compressions and Rarefaction of a Longitudinal Wave: In a longitudinal wave, since the particle motion is parallel to the wave motion, we can observe that there are certain regions where the particles are pressed together and other regions where the particles are spread apart. The region where the particles are pressed together in a small amount of space during the longitudinal wave motion is known as the Compression. This region is also said to have the maximum density as the particles are pressed tightly when the longitudinal wave passes through it. The region where the particles are spread apart in a small amount of space during the longitudinal wave motion is known as the Rarefaction. This region is said to have the minimum density as the particles are spread apart when the longitudinal wave passes through it. During the longitudinal wave motion, there are alternating compressions and rarefactions generated along the wave, as shown in the figure above. Properties of a Wave: A wave motion has various properties and some of the terms that describe a wave are amplitude, wavelength, frequency, time period, etc. Amplitude: The maximum amount of displacement of a particle from its rest position during a wave motion is known as the amplitude. Amplitude is measured as the distance from the rest position to a crest or the distance from the rest position to the trough. Wavelength: In a transverse wave, the wavelength is the distance between crest to its consecutive crest or from trough to its consecutive trough. In a longitudinal wave, wavelength can be referred to as the distance between consecutive compressions or consecutive rarefactions. Since a wave repeats itself periodically over time and space, hence a wave is known to have a repeating pattern. Therefore, the wavelength can also be simply measured as the distance from a point on a wave to the corresponding point on the waves next cycle. Frequency: It is the measure of the number of waves that pass through a fixed place in a given interval of time. This implies that in a given amount of time, the number of complete cycles of wave that passes through a medium at a certain point is known as the Frequency. Usually the units of frequency are given as cycles/second, vibrations/second, waves/second. However, the standard unit commonly used for frequency is Hertz denoted by the symbol Hz. 1 Hertz is equal to 1 cycle/second. Examples: If a coil of a slinky makes 5 vibrations per second, then its frequency is 5Hz. If a coil makes 12 cycles per 3seconds, then its frequency = 12cycles/3seconds = 4Hz. iv) Time Period: During the wave motion, the time taken by a particle in the medium to make one complete vibrational cycle is known as the period or the time period of a wave. Example: The period of orbit of the Earth around the Sun is approximately 365 days. Period and Frequency are related by the relationship: Frequency = 1/Period This equation can also be written as Period = 1/Frequency Example: A period of 8seconds corresponds to what frequency? Given: Period = 8 seconds Frequency = 1/8 = 0.125Hz Wave Equation: The wave equation is a mathematical equation which describes the relationship between the speed of a wave, the wave frequency and its wavelength. The Wave Equation: Speed = Frequency * Wavelength == v = f * Here, v = speed of the wave f = frequency of the wave = wavelength of the wave Example: If the speed of a wave travelling in a medium is 600m/s, then what is the wavelength of the wave if 1800 waves pass through a certain point in a minute? Given: speed of the wave, v = 600m/s Number of waves passing through a point in a minute = 2000 This implies, that the frequency of the wave = 2000 waves/minute Hence, waves per second = 1800 waves/minute * 1minute/60seconds = 30 waves/second = 30Hz Speed = Frequency * Wavelength == wavelength, = speed/frequency Hence wavelength, = 600/30 = 20m Therefore the wavelength of the given wave is 20m. Example: What is the frequency of the light whose wavelength is 600m? Given: wavelength, = 600m Speed of light, v = 3.0 * 108m/s (speed of light is a constant value) Speed = Frequency * Wavelength == frequency, f = speed/wavelength Hence frequency, f = 3.0 * 108/600 = 5.0 * 105 Hz Therefore the frequency here is 5.0 * 105 Hz Electromagnetic spectrum: The distribution of electromagnetic radiation according to the energy, depending on factors such as wavelength and frequency is known as the Electromagnetic spectrum. All the waves including the light rays that our eyes can see, the microwaves, radio waves, X-rays, gamma rays etc. all belong to the electromagnetic spectrum. The visible light of the electromagnetic spectrum consists of the colors that we usually see in the rainbow.
