Focus study sessions to meet your individual needs Every student is different and will need help with different aspects of their AP courses. In general, students are encouraged to sign up for a course within a field of study that they are interested in or have a talent in. However, sometimes students are limited to courses that their school offers in a particular year. Students are encouraged to look at their strengths and weaknesses or enlist the help of a professional who can create a study plan that will help them succeed. How much a student studies and what they study will also be dependent on the score theyre hoping to earn. Different colleges and universities will have varying standards and students are encouraged to look up this information in advance. Join TutorNerds for our Group AP Exam Prep Classes in Irvine 3. Writing samples Students who are in writing-intensive courses are encouraged to do a few practice essays or free response questions as part of their study plan. Students can start by responding to a sample question and take as long as they need. Its important not to have too much pressure in the beginning but, by the time students take the real test they should be confident they can complete their essay within the amount of time allotted. The more students practice, the more likely they are to be able to respond to a question quickly and efficiently without having to make too many grammar or spelling corrections. 4.

Intermediate Students Choosing Between Physics, Chemistry and Biology
Intermediate Students Choosing Between Physics, Chemistry and BiologyAs a student, intermediate level students are not allowed to choose from the three subjects namely; physics, chemistry and biology. Since biology is a compulsory subject in high school, it is mandatory for every high school student to take it before leaving school. The subjects are highly respected in most of the colleges and universities.It is a system that is divided into the levels which are separated into two categories i.e. Physics, and Chemistry. The Physics course can be called the first tier. This is required for those students who had taken up science subjects in their high school and wish to pursue it further. It is a subject that can be taken by those students who wish to become an engineer or scientist.For some students, this course is not good enough and they wish to take up Biology, so that they may get the required knowledge to help them in their career. With this objective, there are many colleges an d universities that offer introductory biology courses.Another subject for intermediate students is Biology, and this course is obligatory for those students who had taken up physics and chemistry but not biology. Biology is required to ensure that an individual can take up well his career or other knowledge and skills required.While chemistry has been recommended by many medical professionals and doctors as the cure for a lot of diseases, it has a few limitations. These limitations are that it does not give any information about the earth sciences and its relationship with other subjects.While biology is required to become an engineer or scientist, physics is required to study natural sciences. It is a subject that is required to help the individual to complete his studies. It is compulsory to take up the physics course at the institute or college. For an advanced student, it is very necessary to know the details of all the subjects and study at a pace where he can handle all the w ork of the subject.An intermediate student has the option to take up the classes in the evening or during the weekend without any need of spending money on travel or accommodation. It is therefore essential to seek the permission of the college or university regarding the days and hours when the class can be taken.
Types of Alcohols - Chemistry Basics
Types of Alcohols - Chemistry BasicsIf you have ever taken a chemistry class or worked with chemical compounds, you are probably aware of the different types of alcohols. Whether you are a chemist, a chemist student, or even if you just know the names for these types of compounds, you have at least an idea of the nature of the alcohols. In fact, it is possible to distill your own alcohol by using a vessel that is made from glass. Glass works well because it lets the alcohol evaporate while leaving the liquid behind in the glass.Alcohols are classified as hydrophobic and hydrophilic, which is based on the way they attract and repel other substances. There are two types of alcohols: simple and complex. As you continue to learn about these different types of alcohols, you will learn more about how they behave and what properties they have.Alcohols are among the most widely used chemical compounds. Many of them are used in medicine and in the food industry. Because of their ability to be broken down in the body, many medical researchers use these types of compounds to study different health issues. Some alcohols, such as methanol, are poisonous. Other types, such as ethanol, are described as highly flammable.When scientists study alcohols, they are interested in the chemical makeup of the compounds. Most people recognize the most common types of alcohols as acetone, but some researchers refer to acetone as methylene chloride. Other compounds are methylene chloride and ethyl alcohol.Ethanol is one of the more common alcohols. It is the most common form of alcohol used in the United States. Ethanol is used in food, fuel, and chemicals. The other types of alcohols are mainly used in industrial production.If you are interested in learning more about the chemistry of alcohols, you can go online and find online courses that teach you about all of the different types of alcohols. These courses will give you a good overview of the basic concepts about these compounds. You will also be able to learn the names of the most common forms of alcohols. It is also possible to take courses that offer you a hands-on approach to understanding the process of making alcohols.You can search online for a number of chemistry courses about the chemistry of alcohols. Some of these courses are free and some may require you to pay a fee. Make sure that you understand all of the information that you learn about these compounds.
Should I Go To Indiana University
Should I Go To Indiana University The tutors behind Varsity Tutors are not just here to teach theyre sharing their college experiences as well. Michelle is a Pittsburgh tutor specializing in Algebra tutoring, Reading tutoring, Phonics tutoring, and much more. She earned her Bachelors degree in Elementary Education from Indiana University in 2011. Check out her review of her experience at Indiana University: VT: Describe the campus setting and transportation options.How urban or safe is the campus?Are there buses or do you need a car/bike? Michelle:Indiana University is often considered one of the most beautiful college campuses in the nation. It is a great place to walk around, and it makes the stroll to class enjoyable. The town itself is eclectic and creative, featuring cuisine from all over the world, many inviting performance spaces, and tons of small businesses. It is considered an urban campus, but the town and the university are divided by Indiana Avenue. Both are easily accessible by foot. The university and city both offer busing options that are free to students, and they run quite often. Having a car on campus is not necessary, but it can be helpful for grocery shopping or trips to Walmart. VT: How available are the professors, academic advisers, and teaching assistants? Michelle:During my time at Indiana University, I often met with professors. They were always willing to meet in person or to have a conversation over email. Before class, after class, or office hours were always available. I also had a very good relationship with my academic adviser, who would schedule appointments with me at any time during the semester. VT: How would you describe the dorm life rooms, dining options, location, socialization opportunities with other students? Michelle:At Indiana University, dorms are designated by neighborhood: Northwest, Central, Southeast, etc. When you request dorms, you request by neighborhood, not specific building. There are many options to choose from, including themed floors ranging from outdoor sports, to the global village, to honors. During the year, there are plenty of social events planned by floor and also by dorm. They are widely advertised on bulletin boards and on walking paths in chalk. Dining-wise, Indiana University is the place to be! The two biggest dining halls are in Northwest and Central. However, there are also smaller food options in many of the dorms. Some are vegetarian, others are cafeteria-style. There are also dorm convenience stores called C Stores that take meal points. I encourage students to visit as many dining halls as they can. After freshman year, there are some newer suite-style dorms available. However, it is not unusual for upperclassmen to live in off-campus apartments and houses. VT: Which majors/programs are best represented and supported?What did you study and why? Did the university do a good job supporting your particular area of study? Michelle:Indiana University is a proud research institution. Professors are often highly regarded in their fields. The two most prestigious programs are the Kelley School of Business and the Jacobs School of Music. Both of those programs are very challenging to get into, and they hold high reputations in their industries. However, many other areas of study are high ranking but do not receive as much advertising. I studied elementary education with the School of Education. I knew that I wanted to be a teacher right away, which was helpful because the program is very rigorous with many prerequisites. There were many professional opportunities and programs provided through the School of Education. Additionally, I felt the faculty and advisors were knowledgeable and helpful throughout my tenure. VT: How easy or difficult was it for you to meet people and make friends as a freshman? Does Greek life play a significant role in the campus social life? Michelle:Making friends is easy if you take advantage of the opportunities afforded you. Social groups and activities are advertised on dorm bulletin boards, on chalkings throughout campus, and in the student paperThe Indiana Daily Student (or IDS). There are lots of different groups, some social and some community service oriented. During the first week of the fall semester there is a student activity fair, and it is a great place to look for clubs to join. Greek life at Indiana University is very large, but it is not everything. I myself was a member of a sorority. I made wonderful friends and was able to take a large leadership role. I also felt more involved in campus events, such as Little 500. However, I also had friends outside of Greek life who were very social and involved. VT: How helpful is the Career Centerand other student support services?Do many reputable companies recruit on campus? Michelle:The Career Center was helpful, but the advisers within each school tend to be more knowledgeable about specific fields. There were many support services on campus, but you need to know where to look. Also, I have many friends from the university that now work for Kohls, Target, Dicks Sporting Goods, Google, and Deloitte. Internships are important, as well as taking advantage of networking available through Indiana University events. Most of these friends earned degrees through the business school and the School of Public and Environmental Affairs. VT: How are the various study areas such aslibraries, the student union, and dorm lounges? Are they over-crowded, easily available, spacious? Michelle:There are lots of study areas around campus. What makes this great is that there are different types of spaces for students who want various environments to do work in. Indiana University has one of the largest student unions in the nation, and it includes many different spaces to work. One of the coziest is the South Lounge, which many refer to as Hogwarts. There is also a Starbucks with sprawling tables. There are computer labs and other communal seating areas all throughout campus. Additionally, most academic buildings have their own libraries. The main library, Herman Wells, is open 24 hours a day, seven days a week. Each floor serves its own purpose: group work, computer stations, presentation rooms, and the graduate tower stacks. Also, the library has many dining options including Chick-Fil-A and Pizza Hut. Some study spaces are more popular than others, and they often get more crowded during midterms and finals. Students tend to find the spaces on campus that work best for their schedule and style of work. VT: Describe the surrounding town. What kinds of outside establishments / things to do are there that make it fun, boring, or somewhere in between?To what extent do students go to the downtown area of the city versus staying near campus? Michelle:Indiana University is in Bloomington, Indiana, which is easily one of the best college towns in the nation. Known for its beauty and culture, there is always something fun to do. The town is integrated into the university, but it really begins just past the Sample Gates. Kirkwood is the main street, filled with shops both local and chain. Bloomington offers endless dining options for any budget. 4thStreet is known for its blocks of foreign restaurants. Besides the dozens of restaurants, Bloomington has many local stores and businesses. Walking into town is always an adventure, with lots of choices for shopping at interesting stores. Bloomington is also big on local and organic food. They have their own version of Whole Foods called Blooming Foods, and there is a huge weekly farmers market from August to November. For students over 21, there are many, many bars in and around the squaresomething for any crowd or mood you may be in. There is also locally brewed beer at Upland and a winery, Oliver, just 30 minutes away. Students at Indiana University barely notice being on- or off-campus. Campus is part of the city, and the city feels like an extension of the university. VT: How big or small is the student body? Were you generally pleased or displeased with the typical class sizes? Michelle:Indiana University serves about 40,000 students, most of whom are undergraduates. It is a large student body, but by getting involved with clubs and campus groups, it starts to feel very small. I was pleased with my class sizes. I found it to be a myth that large colleges only provide lectures. While my introduction courses and some program requirements included large lectures, the majority of my classes had about 30 students in them. Also, most of the large lectures also had smaller discussion sections that met at separate times during the week. VT: Describe one memorable experience with a professor and/or class. Perhaps one you loved the most or one youregretthe most. Michelle:Even though I majored in elementary education, I was eager to explore many subjects in college, including political science. I took Introduction to Political Science as an elective during the fall semester of my freshman year. My professor was expressive and interested in what we were studying. He also loved to facilitate class discussions that often turned one students views on another. Our readings included The Republic by Plato, one of the most difficult texts I have ever encountered. The professor recognized this and offered extra review classes with the two teaching assistants to help. I also went to see him during office hours for help with our final paper, one that I agonized over and spent hours on. He was very helpful and constructive. This professor also offered me guidance when I lamented that I could not add a political science minor onto my elementary education major. He gave me advice about how to fit in other political science courses and which ones would be m ost beneficial. Although I only took one class with him, for the rest of my time at Indiana University, he would always stop to chat or say hello when I saw him on campus. Big schools can have small school connections and relationshipsyou just need to foster them. Check out Michellestutoring profile.

10 Things Every Great Jazz Guitarist Knows
10 Things Every Great Jazz Guitarist Knows Megan L. Be the next great jazz guitarist with these tips from guitar teacher Zachary A. To quote the late Frank Zappa, âJazz is not dead, it just smells funnyâ. Jazz may not be as big and popular as it once was but if you learn how to play jazz you will be set up to successfully play any genre of music. The great jazz musicians all have numerous things in common, things that set them apart from the crowd and make them legendary. In this article, I will be going over ten of those most important things that anyone playing jazz guitar must know. Remember that as a jazz musician, and really any type of musician, you should be listening to as much music as possible. Listening to great performances really is vital for becoming a great performer yourself. 1. Timing is everything Timing in music is imperative, and especially in jazz. Music itself is the manipulation of time. When you play music with people and you donât have a good sense for time, the music you create will most likely be a jagged, clustered mess. The people you play with will not know what to play or when to play. Timing is everything. 2. Practice with an external time source A good tip to obtain a little bit more of a jazzier feel to your music is to use a metronome or even a drum sequencer. If if the time signature fits, practice playing on the 2nd and 4th of the beat. The more you play with a metronome the better your time will be. It is that simple. 3. All jazz musicians have a great ear The most common trait in every jazz musician is that they have an impeccable ear for music. Developing a musicianâs ear, as it is referred to, takes time and lots of practice. To help build a better ear for music there are numerous exercises that you can do. Training your ear can involve hearing intervals, lines, chord qualities and chord progressions, and learning all of this in every key, with the ability to decipher what change, what interval, what progression is in what key. Jazz guitarists should also have a great ear while on the bandstand. It is imperative to listen to your band mates while on stage. The better your ear is on stage, the more people will want to play with you. 4. Take every opportunity for a session or gig Take every opportunity for a session or a gig. Every time you play a session or gig it is a learning experience. Through these experiences be sure to take the opportunity to learn from other successful musicians. Always keep an open mind; I am sure that there is something you can learn from just about every musician out there. At times it is easy to get stuck in a narcissistic mind set, trying to find your own solutions to your own problems. Having a handful of trustworthy musicians to go to when you get stuck can be very helpful when youre studying music. Another reason that it is important to take every session or gig you can is because you never know who you will run into at these events. It has been said that music is about being in the right place at the right time. For that luck to strike, you actually have to be out playing and engaging with other musicians. You never know which gig or session will be the one that could change your career. 5. Practice everyday This is pretty self-explanatory. To be a great jazz guitarist, it takes practice and lots of it. Practicing daily, even if it is just for an hour, is way more beneficial than practicing for 8 hours one day and not at all for the rest of the week. 6. Have an extensive amount of heads and changes memorized All great jazz musicians have a back log of themes and heads memorized with the ability to recall them at any time. This knowledge of heads will be extremely beneficial when playing at a jam session or playing a gig. When deciding on what to learn, I recommend start off by learning some of the more well known jazz standards. For example, Autumn Leaves is a well-known song which is played in the key of g minor. Another well-known jazz standard that is essential to have in your repertoire is the song Summertime. A George Gershwin classic, the jazz version was made famous by John Coltrane and has since been covered by many other legendary musicians. Summertime utilizes the major and minor pentatonic scales. Learning this song will help you be a master at these scales. A few more common jazz standards you should learn include Cherokee, All the Things, and Stella by Starlight. When learning these songs transpose them for all 12 keys for complete mastery. 7. Always go back to the fundamentals Jazz is a complex genre, and it is always important to revert back to the fundamentals when learning jazz guitar.This means spending time reviewing the major and minor scales and practicing the pentatonic scales before breaking out in Frank Zappaâs solo in Black Napkins. It is important to know a multitude of chord progressions and phrasings as well as the different forms these phrases can be arranged. Again, it is important to know all these phrases and chord progressions in all of the 12 keys. Another helpful way to learn and master the fundamentals for anyone playing jazz guitar is by learning and getting a general sense of the piano. 8. Talent is great but determination and perseverance win every time Talent is great but perseverance and determination will triumph every time. Being naturally talented at anything is always a nice thing. The one thing that every jazz musician has in common is that they have spent many dedicated hours in the shed practicing and perfecting their trade. Remember the path to learning one hundred songs begins with learning one. 9. There is no set formula for becoming a jazz musician There truly is no set formula for becoming a jazz guitarist and musician, but there are many different formulas out there that you can pick and choose from. In the end, use what works best for you. With jazz there really is so much information out there. There is always room for improvement. You could always be brushing up on changes, learning old jazz standards, or perhaps learning new scales. It is important to steer clear of the mind set of being overly confident in your abilities. This bottomless pit of a mindset can cause you to become complacent and lose that drive every dedicated jazz musician has. One common thing in jazz is that it will take you years to learn, a challenge that I just love. 10. Set goals and stick with them until completion To avoid getting stuck in a rut, it helps to set goals. Both short and long term goals will help you grow as a musician. Your goal could be as simple as learning one new song a week. There is something though, that is even more important than setting the goals, because in reality setting the goals is the easy part. The hard part, and the most important, is to finish the goals you set. Working with a guitar teacher is the best way to meet your goals and achieve your dreams!

Magnetism and Electromagnetism Everything You Need to Know.
Magnetism and Electromagnetism Everything You Need to Know. Your Guide to Magnetism, Electromagnetism, and Electromagnetic Induction. ChaptersWhat is Magnetism?What is an Electromagnet?What is Electromagnetic Induction?What is a Transformer?In the modern world, we use magnets in an overwhelming number of different ways. From the way that a fridge door closes to the way in which your headphones play music, from the generation and transmission of electricity, to the motor in your car. All of these use magnetic force in some way or another.Given the current ubiquitousness of magnets, our particular civilisation would be a bit useless without them. Weâd have no way to move electric currents across the country. All of our electric motors would be useless. And we wouldnât be able to talk across distance â" as we have become so used to doing.As such, we shouldnât take these particular things for granted. Rather, we should â" all of us, that is, not just the scientists â" try to understand what they are all about: how they work, what the special relationship is between electricity and magnetism, and how they make our world go around.This is our special task in this series of articles: to allow everyone to understand why it is that electrons have a magnetic moment, say â" or why an electric current might produce a magnetic field. Why it is that magnetic flux can induce an electric charge, or why all of this stuff is so important for our world.Letâs take a look â" from the basics of the magnetic field to the most important of the magnetic technologies.On Superprof, you can find a physics and maths tutor s1. Electromagnetism is used everywhere.

It is a ânoncontactâ force that affects every single different object in the world, to a greater or less extent, and t hat is the result of the movement of these subatomic particles, electrons, and their electric charge.Electrons, Magnetic Moments, and the Three Types of Magnetism.Every atom in a substance is made up of particles, including the neutrons, electrons, and protons. In magnetism, it is the electrons that are doing the work.These tend to orbit the neutrons, and they each have their own charge â" either positive or negative. What generally happens is that the electrons âpairâ with those of an opposite charge â" meaning that an electron with a negative charge would pair with one that is positive â" and so the material would be relatively stable, as each of the charges would cancel the other out.When substances have paired electrons, we refer to it as diamagnetism.However, there are plenty of types of materials â" including oxygen â" that have unpaired electrons. When this happens, the substance becomes much more magnetic, as the electrons can all align. In most of these materials, however, they do not, as the âmagnetic momentsâ of each of these individual electrons are not equal â" unless they are under the influence of an external magnetic field.These substances which only demonstrate magnetism when they are in an external magnetic field we call paramagnetic.And, finally, there are the ferromagnetic substances. These are the magnetic materials which have unpaired electrons of the same magnetic moment. This means that, spontaneously, they can become magnetic â" and they will remain magnetic even after the removal of an external magnetic field.What, then, is the Magnetic Field?Every magnet or magnetic object has a magnetic field â" the neighbourhood around the magnet in which its magnetic force is present. It is the space affected by the magnetâs magnetic charge.Permanent magnets and electromagnets have enduring magnetic fields, which you will conventionally see with iron filings that arrange themselves into the shape of the magnetic field lines. Thes e will follow the flow from the magnetâs north pole to its south pole.Magnetic fields change depending on the strength of the magnet.Find out more about magnetic fields! What is an Electromagnet?Apart from the magnetic moments of the electrons, the other thing that produces magnetic fields are electric charges. This discovery, back in the 1830s, has been one of the most important in history, as it created the link between magnetism and electricity.Weâve just seen that electrons in a substance have a magnetic charge â" due to the fact of their movement within the magnetic material.But the place in which electrons really move is in electric currents, which, really, are just the movement of electrons. As currents move down a wire, the wire becomes magnetized as the movement of the electrons produces the magnetic field.It was André-Marie Ampère who discovered this, as he showed that parallel wires would attract or repel each other, depending on which way the current would pass. (He would later give his name to the amp or ampere, by the way.)How to Make an Electromagnet.Since the very earliest electromagnets, the technology has not changed very much. They have become stronger, yes, but the overall structure of the devices has remained the same.Electromagnets are made of a coil of wire, wrapped around a core of metal (usually a ferromagnetic material like iron). Into the coil of wire is passed an electric current, whose magnetic field is centred into the hole in the coil â" i.e. the iron core. This whole structure is known as a solenoid â" and is still used in all of the places where electromagnetism is in action.As soon as the electric current is switched off, the solenoid ceases to be magnetic.A Note on the Relationship between Magnetism and Electricity.Whilst we know that electricity produces a magnetic field, and that magnetic fields rely on electrons, the distinction between a thing called magnetism and a separate thing called electricity is a false one.These are not discrete forces. Rather, they are the same physical principle â" like two sides of the same coin. âElectromagnetismâ as a thing is actually one of the f undamental forces in the universe.You find out more about electromagnetism in our dedicated article.What is Electromagnetic Induction?One of the most useful discoveries in the history of electromagnetism was made by Michael Faraday, a British scientist in the nineteenth century. This became known as electromagnetic induction â" and it remains one of the core parts of our knowledge of electromagnetism to this day.Faradayâs experiments focused on the way that electric charges can be manipulated by magnetic fields. And he surmised that changes to a magnetic field can be used to induce an electrical current.This sounds complicated, but his actual practical experiments were fairly simple. He took an iron ring and wrapped two different wires around opposite sides of the ring â" producing two solenoids on the same piece of iron.Attaching one piece of wire to a battery, he attached another to a galvanometer, a machine which measures electric charges. Connecting and disconnecting the fir st wire from the battery produced a change in the charge detected by the galvanometer. This, for Faraday, proved that the change in the magnetic field in the iron ring could induce an electrical current on the separate wire.To prove his ideas about this particular relationship between electricity and magnetism, he did another experiment. Taking a solenoid without a core (so just a wire coil), he inserted a bar magnet in and out of the coil. Pushing the magnet faster, he found a larger current was produced in the wire.Why was this so important? Because Faraday paved the way for the knowledge that electrical currents donât only flow through wire â" whilst he set the theoretical ground on which we came to produce electrical energy by manipulating its magnetic field.Learn more about electromagnetic induction! A diagram of a magnetic fieldWhat is a Transformer?Transformers are the crucial piece of technology that use the science of electromagnetic induction.They are perhaps the most common electrical devices on the planet, with almost the entirety of electrical energy that we produce and use passing through at least one transformer in its journey.So, what are transformers? A transformer is a static device that changes a current of a high voltage into one of a much lower voltage. It does this through the presence of two adjacent solenoids and through Faradayâs electromagnetic induction.Across the country, electricity is transmitted through massive electrical networks. But to keep costs down, the electricity that is transported is of super high voltages. This â" rather than a high current â" reduces wasted energy and means that the wires themselves donât need to be big.However, we canât actually use high voltage electricity. So, before the electricity is distributed locally into our homes, it needs to be transformed into lower voltage electricity. Thatâs what transformers are for.Reducing Current Voltage.Faradayâs law shows how electromagnetic induction can be used to reduced and increase the voltage of electrical currents.Think back to his experiment: he used two different coils, in which the changes in magnetic field between the two induced an electrical current in the second.If, however, you vary the number of coils in the wire, you can change the voltage of the current induced. Say you have ten coils on the first wire, you can simply halve the number of coils on the second and you have half the voltage.This is precisely how transformers work.

ChaptersDisparity in Teachers Pay ScaleTeacher Salary based on Seniority and TenureHow Seniority in Primary and Secondary Education affects Teachers PayExperience is (not Necessarily) what Matters Most with Teachers Pay ScaleThe Significance of STEMWhat about Maths Teacher Salary?If you've ever had occasion to talk with a maths teacher, during a parent-teacher conference or during a spontaneous consultation on your child's progress, you might have sensed a feeling of malcontent underlying his/her assertions.Frustration over heavy workload has pushed more educators to become a maths tutor recently. Teaching geared to ensure students pass mandatory exams instead of delving deeper into curriculum, aspects that would guarantee true learning, is another great source of ire.Impossibly high standards to reach which, by the way, determine a master's earning potential.Is teacher pay really scaled on a pupil reaching learning milestones?How is pay determined for maths teachers in the UK?These permanent posts were few and far between; highly coveted and stingily awarded.Soon, such appointments will be a thing of the past. As the last of the Positioned Professors retire or withdraw from academic life, their posts will be filled by teachers on contract with no possibility of gaining tenure at their institution.The Education Reform Act of 1988 changed the nature of post-secondary schools from mere institutes of higher learning into businesses. That in turn altered the relationship of Professors with their domains.No longer would schools vie for especially talented teachers; nor would genius be particularly cultivated.Everyone signs a contract: permanent, indefinite or school year to school year.This move was meant to narrow the gap between academic institutions and polytechnic schools. Public school teachers at Polytechnic universities have always worked under contract, and such houses of learning have always been 'for profit'.1992 saw a further narrowing of the gap between the two types of schools: all polytechnic colleges became Universities.From then on, any illusion that academic professorship conveyed gravitas was irrevocably destroyed. healthcare to education has adopted it, to one extent or the other.Pay for Performance, ExplainedLet's imagine a particular school district that, for whatever reason, consistently under-performs: the rate of school leavers is fantastically high, test scores are abysmally low and teacher turnover rates are appalling.In spite of regular teacher evaluation and a salary schedule commensurate with other schools in the area, the school administrator has little recourse in improving the educational statistics his facility seems to constantly churn out.Naturally, there is the matter of accountability: are all of the good teachers leaving because the teachers who could benefit from more guidance and development simply aren't getting it?Are the students' education statistics due to the education system failing in their recr uitment of qualified, experienced teachers?Oh, well! Time to sort out the bonuses, now! Let's see... Sir John has been here the longest so he will get the largest cheque, followed by Mrs. ...Therein lies most of that school district's problems.Disbursing loyalty bonuses rather than merit bonuses tends to make employees loyal to the bonus rather than to their employment.Just after the turn of the century, corporations and administrative bodies alike, including our country's Department of Education adopted a supplemental compensation scheme that places the onus on teachers' self-improvement that would lead to better classroom performance rather than to automatic and incremental increases in teachers salary.Here we note that, although teachers do not receive a cost of living allowance, the average teacher salary does increase to reflect the cost of living, year to year.This system of merit pay compels teachers to focus more directly on student achievement and incentivises them to take on extracurricular duties, such as working with SEN students, as mentioned above.However, it makes no allowance for STEM education - instructional programs in science, technology, engineering and maths that is currently THE hot topic in education today.A topic that, till now, haws received no more school funding than any other academic subject.Too few students in our schools see the melding of maths, engineering and technology Source: Pixabay Credit: GeraltThe Significance of STEMEvery aspect of our daily lives is impacted and influenced by STEM. We won't belabour the obvious by citing online shopping statistics or the prevalence of social media - two aspects of modern society wholly dependent on technology. Instead, we point to the road you take to work, the conveyance you arrive in, be it your own car or the tube...Did you listen to music or perhaps an audiobook on the way?Without the study of science and engineering, none of those conveniences would exist for us to enjoy, and wit hout maths, technology and engineering would, dare we say, not exist?Just last weekend, at a forum held in Dubai, the Global Education and Skills forum discussed, among other topics, the need for more and better teachers, who could make the subject material come alive for their students.What's the point of studying maths and science? - a common student complaint.The point is that the the science, engineering and manufacturing sectors estimate a shortfall of 80,000 qualified workers in the next two years - a terrifying statistic!What are we, in Great Britain, doing to head off those potentially disastrous circumstances? Outreach projects to attract more female students to STEM have not been wholly successful. Still, organisations such as STEM Learning work hard to promote interest and awareness of STEM in schools across the country.They work directly with students but their main function is to support STEM teachers, through continuing education, by helping develop teaching strategie s and by disseminating new information as soon as it becomes available.So, with the spotlight currently on STEM subjects and those teachers doing everything they can to impart their subject matter in the most engaging ways possible... What about Maths Teacher Salary?Till now, the UK school system makes no distinction between a teacher of Maths and of any other subject, when it comes to pay.Teachers of all subjects are compensated according to their experience and performance, and all fall within the salary range for their level.According to Elizabeth Truss, such unremarkable treatment of maths teachers and cavalier attitude toward maths in general, will certainly lead to Britain falling behind other countries national education systems. In China and South Korea for example, where pupils excel at not only maths but science, biology, literacy and more.She faced great criticism for her position on boosting pay and incentives to attract quality maths instructors and recommending that qualifications for maths teachers be more stringent.Until now, nothing has been done to especially recognize or compensate maths teachers beyond what teachers of other subjects earn.We sure hope that will change.
