What Is IER?

What Is IER?One of the biggest questions I get asked when I teach students how to write chemistry essays is 'What is IER?' There is no real definition for this term, so it is best to let students use their own interpretation for what this term means. However, there are certain key points to remember.IER stands for 'It is Okay to Use Exact Substitution' and it is a common process used by chemists. IER takes a chemical formula, such as 'pH=7.00' and replaces the naught with the razzle and then substitutes the other elements with other elements.IER is simply a process that all good chemists know about and is used by almost every chemist out there. The point of IER is that because it is an exact substitution, all changes made to the original formula must be identical.So, what is IER? Well, the formula has to have the same number of non-replaced letters and be exactly one-hundred percent identical to the original formula. Therefore, if a formula is written with two carbon atoms, one carbo n and one oxygen, then the number of the carbon in the original formula must match the number of the carbon atoms in the new formula. For example, using 'C2H5O2' as an example, the carbon in the original formula must match the number of the carbon in the new formula.If you are using IER in your chemistry essay, then you will notice that there are many criteria that must be met for a formula to meet the criteria for IER. Any chemical formula that has two non-replaced letters must be at least one hundred percent identical to the original formula. Therefore, if your original formula has 'C2H5O2' then the '2' must be replaced with 'O' or some other letter, and the 'H' must be replaced with 'I' or some other letter.In addition, if you are using IER in your chemistry essay, then you must make sure that the number of carbon atoms in the original formula is the same as the number of carbon atoms in the new formula. Otherwise, the formula will not be considered for IER. This criterion is bas ed on how chemical formulas are derived from the parent elements. For example, if a formula has two hydrogen atoms and one oxygen atom, then the formula cannot be IER.IER is a very important process that all chemists know about, and is used by almost every chemist out there. Therefore, don't hesitate to use IER to make sure that your chemistry essay hits the high marks. It's an excellent way to make sure that your chemistry essay stays at the top of the class.

Algebra 1 Word Problems Online Tutoring - Algebra Help

Algebra 1 Word Problems Online Tutoring - Algebra Help Various day-to-day mathematical problems or the real world problems can be easily solved by first converting the problem in the form of an equation and then solving it by applying the rules of algebra. Algebra 1 word problems tool helps in solving the word problem step by step. This can be illustrated by a few examples as below. Example 1: If the cost of 12 pens is $50, find the cost of 5 such pens. Solution: Here we cannot find the cost of 5 pens unless we find the cost of one pen, which is also not known, from the question. We start by assuming the cost of one pen to be x, So the cost of 12 pens would be 12 (x) = 12x.. (1) But according to the question cost of 12 pens = $50.. (2) So from the equation (1) and (2) above, we get 12x = 50 Dividing both sides by 12 12x/12 = 50 x = 4.16, i.e. the cost of one pen (3) Now, cost of 5 pens would be 5x. But x = 4.16 as per equation (3) So, cost of 5 pens = 5 X 4.16 = $20.8 Example 2: Find the cost of a bag which was sold for $200 at a profit of 20%. Solution: Let us assume the cost price (C.P) to be =x We know that, Selling price (S.P) = C.P + Profit Or S.P = C.P + P Or, S.P = x + 20% of x (because profit is 20% of the C.P) Or, S.P = x + 20x/100 Or, S.P. =120x/100..(1) But according to the question S.P = 200.(2) From equation (1) and (2) above = 200 Multiplying both sides by 100 Or, 120x/100 * 100 = 200 x 100 Or,120x = 20000 Dividing both sides by 120 120x/120 = 20000/120 X= 166.67, or the cost price of the bag was $166.66

Teaching Children English Using The Six Thinking Hats Technique

Teaching Children English Using The Six Thinking Hats Technique Finding the right way to teach English classes for children can be difficult. How do we keep them interested? How can we help them to remember information? How can we encourage them to want to continue learning?Six Thinking Hats, a teaching model promoting critical and creative thinking attributed to Maltese physician and consultant Edward de Bono, is a great way to get young learners stimulated. It is straightforward, versatile and popular with children, particularly around 8 years and upward, worldwide. So why not use it for teaching young  students English?The theory is that our thought processes (of both young and old) can be predicted in 6 steps and that classes be prepared in accordance with the structure of this 6-part thought processes.The six hats are:White: In this phase we think about the facts of what we are learning. We think about what facts we have and what facts we need to understand a given topic.Black: In this stage we use out judgment. We use our critical judgment. We think about problems, dangers, if we are wasting time with a topic, etc.Yellow: Here, we use our judgment again. However, now we are positive. We think about the advantages, benefits, hopeful side to what we are learning.Red: This stage is characterized by an emotional response to what we are learning. What do I feel about this issue?Green: This is the creative phase. What is my response to this?Blue: This is a development of the creative phase but here we consider the ‘overall’ picture. What are the consequences of what I am learning? What should I learn next?Diagram of The Six Thinking Hats model.How can this theory be applied to teaching children?Children can be given colored pages corresponding to the different hats and or even cut-outs of the hats in their different colors.Over a series of classes they can be taught the associations with each hat and how to express them in English:Objective terms (White hat):We know thatLet’s see what we have already learned…Creativ e terms (Green hat):I believe that…I think that…Positive (Yellow hat):I/We can…I/We shouldNegative (Black hat):I don’t think thatI wouldn’t doIntuitive (Red hat):I feelProcess (or Progress)I would continue by…We should proceed by…Then, present a series of questions for example:What would happen is the world was square?What would happen if your country won the world cup?What would happen if we were all grown up tomorrow?If you are working with a group of children, give them a different color hat each and ask each of them for their response based on the color of their hat.If you are working with an individual child you can rotate the hats and ask for responses to the question based on each one of the hats in turn.Watch this video to find out more:Did you find this lesson helpful?

After Spanish, These Are 6 of the Best Languages to Learn

After Spanish, These Are 6 of the Best Languages to Learn Your Move: 6 of the Best Languages to Learn After Spanish Choosing a language to learn may not seem like a strategic move.After all, for many, Spanish is the obvious choice.But after you learn Spanishâ€"Wait, hold on. After?Well, yes.Spanish covers a lot of the world. English covers quite a bit more. But added together, you might still only get… about a fourth?There are still many, many places around the world where Spanish and English wont get you far at all. Besides, there are plenty of native Spanish speakers looking for additional languages to learn, too, and maybe youre even one of them!So whether youve already learned Spanish, you grew up speaking Spanish or you dont know Spanish but are still curious about what other languages are out there, its certainly worth considering your options carefully.From bustling cities to remote jungle villages, the world is absolutely full of languages. So why limit yourself?Even if youre English-Spanish bilingual, youve still only scratched the surface.Learning an extra language or two will definite ly give you a leg up in business, travel and even your day-to-day life. And looking into languages to learn aside from Spanish will give you a chance to weigh the advantages of each.So, out of the whole  vast linguistic landscape, here are six of the best languages to add on top of your English and Spanishâ€"or just to learn based on their own merits. Your Move: 6 of the Best Languages to Learn After SpanishThe languages below are highlighted for their overall usefulness but also for how they can benefit those who are learning or who have already learned Spanish.FrenchFrench might be the number one obvious choice.English is a Germanic language with huge numbers of Romance loanwords, most of them from French. Spanish is, well, a Romance language to begin with.If you already know English and Spanish, youll go into French basically knowing every other word. Plus, all that grammar that gives first-time French students nightmares? Youll have been over it.And once you learn French, youl l be able to communicate with millions of people all over Europe, Africa and North America  who have learned French as their first or second language.Tip: It’s a good idea to focus on listening from the beginning with French because there are some tricky sounds and the pronunciation isnt always clear from the spelling. Once your listening is strong, its smooth sailing.FluentU has a very robust collection of videos for learning French that you can start using to build up your listening and speaking skills with authentic language right away. FluentU takes real-world videosâ€"like movie trailers, music videos, news and inspiring talksâ€"and turns them into personalized language lessons. You can also check it out for German or Russian (below), and use it to learn Spanish along with any of the languages on this list.PortuguesePortuguese, of course, is already extremely similar to Spanish. Many Spanish speakers can start reading newspapers in Portuguese with little to no preparation.Des pite that, the approximate 220 million native speakers of Portuguese in the world are often quite proud of their own language. Many of them understandably somewhat resent tourists who only bother to speak portuñol (essentially Spanish in a Portuguese disguise).In fact, as Portuguese isnt as well known as French or Spanish, few Portuguese speakers even expect foreigners in their home countries to be able to say more than a few words.That means if you can speak good and correct Portuguese, theyll understand that youve really put in the time to understand their culture and their language, and probably appreciate it.Tip: Since Spanish is so similar to Portuguese, if you want to learn both, the best way to avoid mixing the two is to achieve a very comfortable level in Spanish first (unless you go for Portuguese first, in which case you can do it the other way around). Give your brain two or three years to really internalize Spanish.Then, when you begin learning Portuguese, translate fro m Spanish to Portuguese and vice versa to keep the rules for the two languages separate in your mind.Additional tip: If you want to learn European Portuguese, it can be tricky to find resources online, but this guide should give you everything you need to get started. If youre learning Brazilian Portuguese, here are some apps you may find useful.GermanLots of people say that German has hard grammar. In reality, it just has different grammar.If you already have substantial experience learning Spanish, that experience will have taught you about using the subjunctive as well as grammatical gender in general. Thats a significant advantage.Ordinary, everyday words in German tend to be more similar to English than Spanish, such as Buch for book compared to Spanishs  libro. As vocabulary moves up into higher registers, however, the German words tend to come from Latin roots that look an awful lot like Spanish. One example: To try is  probar in Spanish and probieren in German.Heres a more d etailed look at what learning the German language entails.If you know German, Spanish and English, pretty much every Romance and Germanic language becomes transparent. You could probably pick up Dutch over a summer or Italian in a handful of weeks.And although German speakers have a reputation for speaking perfect English to learners, thats far from a universal guarantee. Even in the most metropolitan cities, people will appreciate that you know their languageâ€"and that opens doors every time.Tip: One of the best free resources for starting out as a German learner is  Deutsche Welle. You can even explore some of their content  through Spanish!ArabicOkay, so none of the varieties of Arabic are related to either English or Spanish. Arabic is going to be a challenge.But if you know Spanish, you have a few tricks up your sleeve.Thanks to around 800 years of Moorish influence in Spain, the Spanish and Arabic languages actually share a deep pool of vocabulary. You cant describe food or a ccommodation in Spanish without tripping over Arabic-derived words like  azúcar  (sugar), alfombra (carpet), albahaca (basil)  or naranja (orange).The benefits of learning Arabic are manifold. The Arabic language covers an enormous swath of the Middle East and North Africa, including millions of people who arent comfortable speaking English or Spanish.Plus, with Arabic, Spanish and English, youll know exactly half of the official working languages of the UN!Tip: Spanish speakers, when it comes time to learn the beautiful Arabic script, you can actually start with texts in aljamiadoâ€"a way of writing Spanish using Arabic letters. Its far, far easier to get used to reading a new script if you already know what it says.IndonesianIndonesian (and its closely related cousin Malay) is the first or second language of millions in Southeast Asia, and thanks to a huge diaspora, people speak Indonesian all over the world, from Australia to the Netherlands. And have you ever dreamed of the whi te sands of Bali? Knowing some Indonesian will help you thrill the locals and make your trip an unforgettable experience.Its true, Indonesian isnt related to Spanish, either. However, as the Malay Archipelago has been a Muslim-majority region for centuries, youll find that quite a few Arabic words in Spanish also appear in Indonesian.And the grammar and pronunciation are extremely simple from a European language perspective. No tenses, no casesâ€"just some interesting verb features.All the time honing your Spanish accent will pay off here: Virtually all the sounds of Indonesian happen to be  found in either English or Spanish!Tip: The biggest hurdle is definitely remembering all the unfamiliar vocabulary. The best way to handle that is to take things slow when you start out and do a ton of review to really make those new words second nature.But theres a great surprise in store, because advanced vocabulary in Indonesian is frequently Latin-based and resembles English and Spanish quit e a bit! No prizes for guessing the meanings of ekonomi or multikulturalisme.RussianNow, Russian is a challenge for any language learner. Between the script and the grammar, its no cakewalk.And yet, although Vladivostok and Madrid are practically on opposite sides of the globe, there are several features of Russian that are quite similar to Spanish.Take the way you say I like it, for instance. In both Russian and Spanish, a construction along the lines of it pleases me is used.Someone who knows Spanish also already has a leg up on learning the sounds of Russian: Your old friends ñ and rr are along for the ride once more.Russian, too, has borrowed heavily from Latin for terms of politics and science. And French was all the rage in Russian aristocracy a few hundred years ago, which means another helping of Latin-derived terms for high society and luxury goods.Russian is spoken across pretty much all of Central Asia to this day. Its even still widely understood in much of Eastern Euro pe, not to mention among the enormous Russian diaspora all around the world.Tip:  Start by doing a lot of listening and reading to get a feel for how all the familiar sounds get rearranged and fit into Cyrillic letter shapes.If you learn another language after Spanish, youll almost certainly gain from some shortcuts like shared vocabulary or similar grammar.But the most important advantage youll have learning any language after any other language is knowing how to learn. Picking up a third language goes significantly faster than your second.But even if youre only starting on your second language now, you already have an advantage in that youre thinking consciously about your choices and considering your options. Why not set the bar high and consider learning multiple languages  so you can reap the benefits?If it takes you three years to get conversational in Spanish, dont be surprised if you reach the same level in Portuguese in less than 18 months.Not only can you quickly relate fe atures of any new language to other languages you know, but if youve previously learned languages you know yourself and you know that, lets say, you really dont like vocab flashcards. So just replace the flashcards with word lists or more reading work. Or focus on listening from the start, if it took you a long time to get used to native Spanish accents.Whatever language or languages you choose, it only gets easier and easier.The only question isâ€"whats next?

Teaching equipment that`s now consigned to the history books - Tutor Hunt Blog

Teaching equipment that`s now consigned to the history books Teaching equipment that`s now consigned to the history books Teaching equipment that`s now consigned to the history booksSchoolsTeaching methods have of course altered dramatically over the centuries, but perhaps the last 50 years have marked the most significant changes in the classroom. Here are just a few things that our parents or grandparents might have seen in their schools, that are now just part of history. 1. The blackboard. There was a time when the word `blackboard` was virtually synonymous with `classroom.` These were basically writing surfaces, upon which the teacher could affix text or drawings to help with their lessons. No styluses or even pens were used - instead a piece of calcium carbonate, or `chalk` as it was colloquially known, was scraped over the black surface, which used to be constructed out of slate, but eventually came to be made from a type of black plastic. By the late 1990`s most had been replaced by whiteboards, which could be written on with pens, and more easily cleaned, without making any clouds of dust. 2. The cane The cane has almost become something of a mythical object - a disciplinary weapon, thankfully consigned to the history books. For decades, perhaps even centuries, it was the dread of schoolchildren. If you were caught misbehaving in class, you could expect to be struck across the hands with the fearsome thin wooden stick. Traditionally made from rattan, a tropical climbing plant, these rigid yet flexible objects could deliver quite a sting, especially when the teacher, for extra points perhaps, would aim to keep striking the same spot. By the 1970`s caning had been largely phased out in the UK, though I can recall being disciplined by teachers holding plimsoles as they would cudgels, in my secondary school in the early 1980`s. 3. The slide rule Before schoolchildren had electronic calculators the slide rule was the hottest piece of portable number crunching technology available. Though it may look remarkably simplistic today, the slide rule is an analogue mechanical computer, capable of a formidable range of calculating applications. Though mainly used for multiplication and addition, it could also calculate exponents, roots, and be used for trigonometric computations. 4. The overhead projector These devices were just being introduced when I left school in the mid 1990`s, and I remember being dazzled by this futuristic technology, that could beam out text or an image onto a screen, seemingly bringing a cinema into the classroom. The device was actually very simple, working along the same lines as a 35mm slide projector - light would be passed through a transparent sheet of plastic, then through a mirror and focusing lens, and finally onto a screen positioned a short distance away. The transparent sheet of plastic acted as the slide, and contained whatever information the teacher wanted to project. The advantage of this system over the blackboard was that the teacher could prepare many sheets in advance, and reuse them in future lessons. Once chalk is wiped from a board it is consigned to dust - sheets for an overhead projector however could be used again and again. Overhead projectors are still used in some schools, but they have largely been replaced by portable flatscreen monitors. 5. The school bell The call to registration, the end of recess - these portentous events used to be announced by someone clanging a bell. In my primary school the end of breaks was always marked in this manner, and it was certainly not a sound we would have risked ignoring for a few extra minutes of playtime. Most schools these days have some kind of electric buzzer, which echoes down the corridors with the aid of loudspeakers, letting pupils know when it`s time to change classrooms or begin their breaks. Who can say what the classroom of the future will look like? With children taking so naturally and instinctively to technology it`s certain that electronic learning aids will become ever more ubiquitous in schools. Since learning involves the moulding and shaping of the developing brains of children, perhaps devices will be developed to achieve this in the most efficient way possible, dramatically shortening the time required for a pupil to progress in mathematics, or learn to play a musical instrument. Whatever the future holds, it is the pupils of today that will bring us one step closer to it. 13 months ago0Add a Comment
