Ratios Are Hard For Student Brains To Learn

Right now, algebra students are studying unit rates, proportions and dimensional analysis. Geometry students are working on similar figures and triangle proportionality theorems. All of these topics are hard for the same reason: They involve ratios, which may seem easy for adults but are actually deeply challenging for the learning brain to grasp. A ratio is the comparison of two numbers, usually using a fraction bar. If there are two dogs and three cats in a room, I could write that the ratio of dogs to cats is 2/3. Like so many things (reading, driving), ratios become second nature with enough practice, and people lose touch with how difficult they were to learn. And like reading and driving, ratios are hard for the brain because they involve simultaneity of thought. The brain is required to multi-task; it must think about the 2 dogs while at the same time thinking about the 3 cats.

Willpower-Friendly Tips For Students And Adults

Willpower is strongest at the beginning of the day and when glucose levels in the bloodstream are adequate.
You can perform better and succeed in getting tasks accomplished if you plan accordingly:

Bring a snack to long exams such as the SAT.
Avoid making decisions before lunch or at the end of the day.
Plan your day ahead of time (that morning or the night before) and then follow your schedule. Don't just float through the day...

The Surprising Key to Willpower

New Year's is the classic time to resolve to form new habits, but most of us then abandon our good intentions by mid-February, if not before. It turns out that our willpower comes, not from the sincerity of our resolve, but from the glucose level in our bloodstream.The brain runs on glucose. Even when not working hard, the brain consumes 25% of circulating glucose, even though it only takes up 3% of the body's weight. Decision-making is especially taxing, and the brain burns glucose like crazy when it's forced to make lots of fine-grained choices over an extended period of time.

Exam Tip: Make the Cheat Sheet You Wish You Could Use

Teachers often allow students to bring "cheat sheets" to exams.

A cheat sheet is an index card or single sheet of paper which the student can fill with all the facts and formulas she needs to know but is afraid she doesn't have by heart. (When given only a 3x5 space to fill, many kids can achieve some truly amazing, near-microscopic handwriting).

Even if you can't actually bring a cheat sheet to the exam,...

3 More Tips to Feel Ready for Midterm Exams

Big exams can seem overwhelming, but there's plenty you can do to get ready. Here are three more tips (I posted the first three here); pick and choose or try them all! Tackle the easy stuff first. Cover the material you know pretty well and then cross it off your list. Start by going through your old tests and quizzes and reworking all the easy problems. This will give you a sense of accomplishment and progress, which will lift your spirits. Let parents help. During stressful times, support from other people can be invaluable. Let your parents remind you to study every day, allow them to clear the family calendar of non-academic events, and let them quiz you, bring you tea or just keep you company. Study alone, then with pals. Don't arrive at a group study session unprepared and clueless. Study alone first so you come equipped with a list of questions plus some knowledge to contribute.

3 Tips to Reduce Midterm Exam Anxiety

Big exams make just about everyone feel anxious. Here are three tips that can help make exam season go smoothly: Get started now. Anxiety builds as you worry and do nothing. It may feel very difficult to get started, but you will feel immediate relief once you do. Begin reviewing now. You need not wait until teachers hand out review guides. Get out your old tests and quizzes and begin reworking them. (Don't merely reread the questions and answers; you need to cover up your old answers and actually rework each problem on paper). Do an overview. Use your notes and/or textbook to write a list of the topics you'll need to know. Making this outline will give you a feeling of control and a realistic sense of the task ahead.
