What Is Percentage Error in Chemistry?

What Is Percentage Error in Chemistry?What is the Percentage Error in Chemistry? Percentage error in chemistry refers to the mathematical formulae for determining the volume or weight of a given molecule or solid substance. For example, a 0.05 percent error would mean that the amount of substance, in this case oxygen, is twice as much as was expected, or twice the normal amount that was supposed to be produced.The moles, ounces, and kilograms are all measurements of mass, which are defined by adding together the number of atoms in a unit of measurement. For example, you might want to know how many grams of carbon dioxide were produced when you burned one liter of gasoline.When measuring volumes, you would use the pound to find out how much water is in your family's shower, or how many pounds there are in a hamburger. When measuring weight, you use the kilogram, for example, which is defined as having the same mass as the U.S. standard. You might not have to worry about such things as mass error in chemistry, because it is common sense that small errors occur every time you measure something in life.However, knowing what is a percentage error in chemistry can help you, if you are in high school chemistry class or a college chemistry lab. If you do not understand percentages, you may come to realize that when measuring something in life, there is an error made on the part of the measuring device.If you want to know more about percentage error in chemistry, there are a number of places to look. Most teachers in high school chemistry may have information about percentage error, so you should ask for help. On the Internet, you will find out about what is a percentage error in chemistry. You might also check the advice that is available at the web site of the American Chemical Society.You can get an idea about the nature of the error by looking at electronic sources, such as the Journal of Physical Chemistry and the Journal of Chemical Education. You may want to read these sources, but you may want to keep the article free from the sometimes hard to understand jargon.It is possible to find out about what is a percentage error in chemistry, because most of us are trying to become more scientific in our own lives. Knowledge about what is a percentage error in chemistry can help you, especially if you have doubts about what is right and wrong, or if you know what is appropriate and inappropriate.

How should I use the Virtual Writing Tutor in 2020

How should I use the Virtual Writing Tutor in 2020 After nearly eight years of development, the Virtual Writing Tutor is becoming a potent resource for students and teachers. Here are some ways you can start using the VWT to help your learners learn faster and better. New ways to use the VirtualWritingTutor.com Free grammar check The Virtual Writing Tutor started its life as a simple grammar check website in 2012. Now, eight years later, there is a lot more to it, but the grammar checker function is still the most popular feature for most of the approximately two hundred thousand visitors to the VirtualWritingTutor.com per month. Perhaps, the biggest reason for its popularity is that it is a 100% free grammar checker, forever. There are other grammar checkers that you can pay for, but I am working hard so that you and your students always have a free option at hand. My theory is that a free online grammar checker can be a source of lifelong learning, but only if students get enough positive experiences using it for the grammar checker to become a beneficial habit. Asking students to use the VWT once or twice a semester is not enough. Heres my advice. How can I use the grammar checker? Whenever you ask students to write something for homework or in the computer lab, ask them to check it for errors using the the Virtual Writing Tutor. Give them a point for using the VWT to eliminate their errors. Tell them that the development of revision strategies is one of the objectives of the course, and give students writing assignments to do every week. Repetition and perceived benefit are the keys to the development of beneficial habits. Read student testimonials about their experiences using the Virtual Writing Tutor. Students cant always see the errors in their own writing, so a quick grammar check on the VWT is a fast and often effective way to eliminate embarrassing errors. Regular use of the VWT makes common errors more visible. Students revise better after a semester using the VWT, even offline and during writing exams. Thats been my experience. Extensive versus intensive correction Research suggests that the best way to influence student accuracy is to provide focused feedback on errors. That means that if you teach past tenses in the presentation and practice stages of your lesson, you should only give feedback on past tenses during the production stage. This is what we mean by intensive corrective feedback. Still, there are many glaring errors that take a long time to explain but are so frequent that teachers cannot ignore them in a students writing. Correction of these incidental errors is sometimes called extensive corrective feedback. The best way for teachers to provide extensive feedback on their errors is to get students to run their texts through the Virtual Writing Tutors grammar checker. Its quick and easy and builds that habit of revision into a weekly routine. Grammar checkers cant detect all the errors in a students writing for two primary reasons. Its partly because not all the error detection rules have been written yet and partly because the system only checks one sentence at a time. A grammar checker such as the VWT cant use the information in the surrounding context of the paragraph or the world at large to determine if the student has used the correct tense. But if a grammar checker is inherently limited, doesnt that mean that it should be avoided completely? No way. Online grammar checkers may be the only solution to the problem of error fossilization. Is there a solution for error fossilization? Ill get into trouble for writing this with at least one of my colleagues, but fossilization is a problem with the instruction not a problem with the student. Think of it this way. The error “I have 17 years.” originates in the students first language, French. Alternatively, consider the widespread use of the first-person pronoun I incorrectly used in lowercase. Through repeated practice of the error without consistent corrective feedback from a teacher or peers, errors like these can become stable and resistant to feedback. After correcting the student twice or three times, a teacher may feel that correcting the student has become a lost cause and pronounce a gloomy prognosis: fossilization! Frequent, repeated, immediate feedback will destabilize even the most entrenched errors. I have seen it myself. In a classroom full of students, more than half of my low intermediates start the semester saying and writing i have 17 years. Through the inherently communicative and repetitive weekly narrative writing assignments in Actively Engaged at College, all the students will have eliminated that error by week 15with the exception of the one student who didnt use the Virtual Writing Tutor. An online grammar checker is the cure for fossilized errors. A fossilized Allosaurus skull. Allo? Allo? Self-Scoring Pen Pal exchange One way to build the revision habit in students is surreptitiously through a self-scoring pen pal exchange. You can set up the exchange between students in the same class or between students of different classes or colleges. As they write about their day, their family, their routine, neighbourhoods, favorite food, memorable day, and a memorable trip, the system counts their errors, their words, and the target vocabulary from the lesson, generating a score. Students seek to maximize their scores by correcting their errors and replying to their pen pals. In this way, using the Virtual Writing Tutor as a revision strategy aligns with their desire for higher grades. When scores align with objectives, students have a better chance of succeeding. The Virtual Writing Tutors Pen Pal Exchange System Automated Argument Essay Evaluation There is so much you can do to help students learn to write better argument essays using the VWT. Here are my step-by-step suggestions. Download an argument essay writing project idea below. Controversial Debate Topic AssignmentDownload First, ask students to sign up to research one of these controversies: abortion, climate change, animal rights, body image, feminism, immigration, or internet censorship. Get groups to research their topic on https://idebate.org/debatabase Ask each group to work together to create a glossary, card game and online matching exercise using the VWTs Glossary Creator. Get each group member to outline an argument essay using the argument essay outliner. Have students draft an essay and get automated formative essay evaluation from the VWT.Have students submit their final drafts to you for your summative feedback and evaluation. Automated Cover Letter Evaluation Lets face it. Some students are sloppy. You show them a standard format for a letter that could get them the entry-level job to start an exciting new career. And what happens? They get it all wrong. So, what do you do next? You spend 10-20 minutes showing them whats wrong with your trusty red pen. Dont get me wrong. I see value in reading students assignments and dramatizing the presence of a reader by commenting on student writing. It is what weve been trained to do, but performing an autopsy on sloppy work is not a very efficient use of our time. Wouldnt it be better if they could just run their letter through the VWT to get the same feedback in two seconds flat? Faster, explicit feedback with a formative score is better feedback. Thats my hypothesis. I have been working with Laurent Nicolas at Andre Grasset College to bring you just such a system. Give it a try. Glossary Maker If you do little else, plan to use theVirtual Writing Tutor’s Glossary Creator this year. Its new and its wonderful. Students can learn so much from this new glossary maker. It takes approximately one and a half minutes per glossary term for a student to do all of the following: add a termgive the part of speechadd a definition in sentence case using the integrated Google definition searchgenerate a text-to-speech pronunciation modeladd an automatic translation It takes another one and a half minutes per glossary term to add the following: images fromWikimedia Commonsauthentic example sentences from theLextutor Concordancer For a 10-term field-related glossary, it will take about 30 minutes. For a 20-term glossary, it should only take about an hour, the perfect activity for students during a computer lab hour. By the end of the hour, students will have a published glossary, a card game to play next class with their classmates, and an online matching exercise to share with classmates in the same program during the next lab hour the following week. Screenshot of a glossary made with the Virtual Writing Tutor An automatically generated card game from a glossary created with the Virtual Writing Tutor An automatically generated online matching exercise from a glossary created with the Virtual Writing Tutor Screencast Creator Every semester, I ask my intermediate students to create two screencasts per semester. Each time, I tell them to write a script and check it for errors. I tell them to use the VWTs text-to-speech button to help them with their pronunciation. What do they do despite my instructions and cajoling? They wing it. The improvised result is predictable. Students work long and hard to produce a screencast filled with avoidable grammar errors and word choice errors and filled with avoidable pronunciation errors, too. I am thrilled to announce that by the end of February, the Virtual Writing Tutor will have a step-by-step screencast creator to help students produce high-quality field-related screencasts for the blogging project that we do with Actively Engaged Online. Of course, you wont need the textbook to get your students to create screencasts with the free system, but it will help if it is your first time teaching blogging. In any case, soon enough, those days will be behind us. If I get my way, there wont be any more avoidable errors and mispronunciations filling up YouTube. My students field-related screencasts are otherwise quite watchable. They just need a little VWT magic polish to make them really shine. New features There are many new features to the Virtual Writing Tutor that you can try. Dont wait another year. 2020 is the best time to start using the Virtual Writing Tutor with your students if you havent started already. I have so many new features planned. On top of automatically evaluating narrative writing tasks, I intend to build a career FAQ blog post creator with embedded meaningful paraphrasing exercises and a listicle creator. You wont believe how good 2020 is going to be! Contact me if you have any questions. Please follow and like us:

Wisdom Comes not from Age, but from Education and Learning.

Wisdom Comes not from Age, but from Education and Learning. Wisdom comes not from age, but from education and learning. Anton Checkov Anton Pavlovich Chekhov was born in the small seaport of Taganrog, southern Russia. Chekhovs grandfather was a serf (kind of slave in Royal Russia), and later he bought the freedom of his wife and children. In 1879 Chekhov entered Moscow University Medical School. As a student, he published hundreds of short comical stories to support himself and his family. In his stories were shown silly moments in society, marriage problems, clashes between husbands and wives, mistresses and lovers, whims of young women, of whom Chekhov had not much knowledge the author was shy with women even after his marriage. His work has appeared in the daily newspapers of St. Petersburg. He is one of the most famous writers in the world. His works have been translated into more than 100 languages. His plays, notably The Seagull , Three Sisters and The Cherry Orchard for over a hundred years, have played in many theaters around the world. During over 26 years of creativity Chekhov delivered out if his imagination about 900 different literary projects (short humorous stories, serious stories, plays), many of which have become classics of world literature.

Internships for Credit What You Need to Know

Internships for Credit What You Need to Know Photo: Pexels How do you know if a company offers college credit? When you are viewing an internship posting, it will usually say whether or not the company offers college credit. If its an unpaid position, they usually do offer college credits for their interns. If it is a paid position, you may be able to switch it out for college credit instead of getting financial compensation. Dont be afraid to ask! Usually, you will have to coordinate with the company you are looking to intern at and an academic/faculty member that will ultimately sponsor/monitor your internship. Make sure you fill out all necessary registration and any paperwork before beginning your internship to get the college credit you want. Keep track of all the steps necessary so that you know what needs to be done and what deadlines to meet. How do you know if you are eligible to get college credit for an internship? Ultimately, it is actually up to your school whether or not you are eligible for college credit. Its not just whether or not the company offers it to begin with, but if your school deems you eligible. You can be denied eligibility for a number of reasons. Maybe you have already taken an internship for college credits and reached the universitys cap for college credits given by an internship. The internship you are pursuing has to tie into your major or field of study in some way, so if it is completely unrelated to your studies, you will most likely not be able to get college credit for the internship. If you are able to find a way to connect your internship to your education, you can see if there is a way for you to submit a petition to get your internship to qualify for college credit. Your ability to be eligible for an internship for college credit also may depend on what year you are in. You may only be able to get an internship for college credit if you are an upperclassman with junior or senior standing in terms of college credits. Also, some majors and minors will require you to complete an internship or field study as part of your requirement for classes. As such, you will get college credit for completing the internship rather than financial compensation. How do you know if an internship for college credits is the right choice for you?   As nice as it is to get out of the classroom and still get college credit, it definitely is not the right choice for everyone. If you are getting an internship for college credit, you will most likely not be getting paid for it as it is usually one or the other. Sometimes you may be looking at multiple internship opportunities and be left completely unsure as to which one to pick. Lay out your options and see which one best advances your career path and gives you the most helpful experience and networking, it may not necessarily be the internship granting you the most college credit. If you are stretched tight financially, you may not be able to have an internship for college credit. Rather, a paid internship may be the better move for you. Dont be afraid to weigh your options. Hopefully, with this guide, your decision will be a bit easier and well-informed.

The New Debx App is Taking the Fear out of Credit Cards

The New Debx App is Taking the Fear out of Credit Cards via Pexels.com Essentially, this free app targets college graduates and millennials and pays off their everyday credit card purchases by linking existing credit cards with checking accounts. This means these individuals are using credit cards like a debit card, which means they reap all the benefits (i.e. rewards and credit building) without the insecurity involved in owning a credit card. As a college student, if you haven’t already, you’ll soon learn the importance of a good credit history. These are important when it comes time to leasing or purchasing a car, renting an apartment or even buying a house. That being said, more and more students are shying away from credit card applications for fear of digging a hole they can’t get out of. According to a recent survey mentioned in the press release, 33% of millennials are afraid of credit card debt. This is shocking given the 20% responding their greatest fear was death. And they aren’t wrong in this fear. Over $1.02 trillion of debt was reached in 2017, with the average American consumer holding $5,290 in credit card balances. This all being said, credit cards are a necessary evil, especially when it comes to building credit. Plus, there are other perks to consider such as reward points, cashback and protection from theft. According to Ben Psillas, the founder of Debx, “When college students graduate, they are often unsure how to build their credit or manage their personal finances, and are maybe even a little intimidated. They leave school with tons of student loans, and they want to avoid getting deeper in debt. But, they need to start building their credit history, and credit cards are one of the best ways to establish that.” The free Debx app allows several options for avoiding the typical, credit card pitfalls. For instance, one big change is the Auto-Pay option, which automatically pays off purchases below a certain amount. In addition, the Shutoff Balance will automatically stop auto-payments when the balance in a user’s checking account is below a set limit. These two tools entirely automate the credit card process, making it rather difficult to find yourself in debt so long as you’re responsible enough to set these amounts accurately in the first place. In this way, they are reaping all the benefits, the points and cashback, without the risk of overspending. Plus, this app is promoting good spending habits, helping you to track your spending in a way that’s less stressful, but still helpful in terms of learning how to maintain good credit. According to Psillas, “College grads should feel confident when using credit, and by letting them stay on top of their balances, avoid debt and reap all the rewards that credit cards have to offer â€" while practically on auto-pilot â€" Debx will help them build that confidence and feel good about how they spend their money.” So, if this sounds like you and you want to download the app to help build that credit without the hassle, you can download the app from iOS in the iTunes Store for free. (The enrollment process will take you about 90 seconds and the app links with most major credit card lenders.)

These meals hold a special place in people’s hearts and hold memories that are hard to recreate as an adult.Of course, even though we have relied on various internet polls our Top 10 remains subjective. The list will inevitably miss thousands of variations and some regions may consider themselves underrepresented.With French gastronomy so incredibly rich the hardest thing was the limit the list to 10…it could have gone on forever!If your favourite dish is missing from our list, share it with your fellow Superprof readers in the comments below!Tartare, comes from, as the name suggests, Tatars (now Ukraine) before it reached the rest of Europe and was adopted by the French.Nowadays you’ll find beef tartare on the menu but traditionally the dish was made with hor se meat. This may sound horrible to us but it is actually very healthy, has a more distinct taste and is less prone to diseases than beef.From one chef to another the way of serving this dish varies; in small cubes, large cubes or served as a haché (like a raw patty).The real differences are found in the accompanying sides. Some serve it with a raw egg on top, with bread and salad, or some serve it with fries.Learn to make it in our cooking classes!CassouletThere has been some debate on the origins of this dish. But it seems to be the city of Castelnaudary in the south of France that has made the most convincing claim, and is now thought of as the Capital of cassoulet!The dish mixes dry beans (usually tarbais â€" a white bean) with pork rind, sausage from Toulouse or duck confit, plus lots of herbs and spices!It’s a great family meal, and accompanied with a quality red wine will warm you up on a winter’s day just before taking an afternoon nap!Beef BourguignonA staple on menus across France (Source: Pexels)Much like stew (the only difference is that the meat is marinated in alcohol before cooking and pig’s feet are often added) this dish is a firm favourite in France and in restaurants around the world.The Bourgogne region can boast about creating this speciality which transforms simple meat into a deliciously rich dish.You must, of course, choose an excellent Bourgogne wine, and don’t forget mushrooms, lard and onions.There is no set accompaniment so you have the freedom to decide what you serve with it: pasta, potatoes or vegetables!BouillabaisseNow we’re going right down to the south of France to get a taste of the Mediterranean.This dish is one of the staples of provincial French gastronomy, where seafood plays a central role.Bouillabaisse is a sort of fish soup made with whole cuts of fresh fish and potatoes and is garnished with garlic or crispy croutons.Cuts of inexpensive fish are used for this soup that we wouldn’t usually eat by themselv es.This dish is straight from fisherman’s families who concocted a recipe to use up the fish they couldn’t sell at the market, and now people can’t get enough of it!MusselsGoing back to the other end of France, to the north, we find a speciality that can also be found across the border in Belgium.‘Moules-Frites’ (mussels and fries) is a staple on menus along the coast of France and indeed across the country, but few people know that the ‘sauce marinière’ that accompanies mussels actually originates in Charentes in the south west of France.It could not be simpler but this dish is delicious, it’s made up of chopped parsley, white wine, shallots, pepper and some sort of fat â€" either olive oil or butter depending on who you ask!). Some fries on the side make it the perfect meal!Bourgogne SnailsTry the most French dish of all, snails!   (Source: divinefishandmeat.com)We return once more to Bourgogne to a dish that along with frog’s legs has become the stereotype of t he French diet for most of us non-French people!Snails are mostly eaten around Christmas time and typically the helix pomatia is the species of choice!First, they are taken out of their shell and then baked in either parsley or garlic butter (which makes them a lot more palatable!). Then they are put back into their shells to be served.Mop up the sauce with a crusty baguette and you have a delicious meal!Do you know much about the History of French cuisine?Or about the diversity of regional French cuisine?Finally, discover more about  French Gastronomy.
