Problem Solving

Devote the time to learn how to do the problem rather then getting to the final answer. Students who simply memorize how to do problems instead of understanding the reasons for correctly working the steps will face more difficulty down the road.

See if you can solve a sample problem without looking at the textbook's solution (unless you get stuck). This makes the best use of sample problems, as students who "understood the lecture" or "read the chapter" often have difficulty doing their first problems using this new-found knowledge.

Draw a picture when you can. Even a poor drawing can be helpful but good ones include parameters, formulas, units, unknowns, and assumptions.

Double-check all diagrams and calculations.

If you can't solve a problem, put it aside and try again later.

Ask yourself if the answer you got seems reasonable.

Try working out at least five new problems each time you study. The true test for determining if you know the material is to do a problem you have never done or seen before.

Study with others. When you work alone and get stuck, you may be tempted to give up. When in a group, you can help each other learn.
