### Previewing

Before class briefly preview the text material that will be covered in the lecture.

- Get an overview of the material by reading the introductory and summary passages, section headings and subheadings, and diagrams.
- Look at the problems at the end of the chapter.
- Make note of new terms.
- Review (if necessary) old terms and definitions referred to in the new material.
- Formulate possible questions for class.

Remember, the purpose of previewing is not to understand the material but to get a general idea of what the lecture will cover. This should **not** be a very time-consuming process.

### Note-Taking

When taking notes in class, listen **actively**; intend to learn from the lecture.

- Write down the instructor's explanatory remarks about the problem.
- Note how one gets from one step of the problem to another.
- Note any particular conditions of the problem.
- Note why the approach to the problem is taken.

- Try to anticipate the consequences of a theorem or the next step in a problem.
- Note any concepts, rules, techniques, or problems that the instructor emphasizes.
- Question your instructor during class about any unclear concept or procedure.
- If you miss something in the lecture or don't understand what's being presented, then write down what you
**can**catch--especially key words. Be sure to skip several lines so you can fill in the missing material later. - As soon as possible after class, summarize, review, and edit your notes.
- Quickly read through your notes to get an overview of the material and to check for any errors or omissions.
- Fill in any information--especially explanatory remarks (see #1 above)--that you did not have time to write down or that the instructor did not provide.
- Use the margin or the back of the opposite page to summarize the material, list key terms or formulas, and rework examples. You can also use this space to take notes from the textbook.
- Note any relationship to previous material; i.e., write down key similarities and differences between concepts in the new material and concepts in previously learned material.

- Review your notes at regular intervals and review them with the intent to learn and retain.

### Text Reading

If your class lectures provide a good overall structure of the course, you can use your text to clarify and supplement your lecture notes. In order to create a single study source, insert the notes you take from the text into your lecture notes themselves as well as in the margin or the back of the opposite page.

If your **text** provides the best overall structure of the material, then you can use your lecture notes as the supplementary source. In either case consider the following procedures:

- Briefly preview the material. Get an overview of the content and look at the questions at the end of the chapter.
- Read
**actively**and read to understand thoroughly.- Formulate questions before you read (from lecture notes or from previewing) and read to answer those questions.
- Know what every word and symbol means.
- Translate abstract formulas to verbal explanations.
- Analyze the example problems by asking yourself these questions:
- What concepts, formulas, and rules were applied?
- What methods were used to solve the problem? Why was this method used?
- What was the first step?
- Have any steps been combined?
- What differences or similarities are there between the examples and homework problems?
- Further analyze the example problems by using the following procedures:
- Explain each step using your own words. Write these explanations on paper.
- Draw your own diagrams to illustrate and explain problems.
- For practice, write down example problems from your book, close your book, and try to work the problems. Check your work with the example to find what concepts, rules, or methods you are having trouble with.

- Check to see how the material relates to previous material. Ask yourself these questions:
- How was the material different from previous material?
- How was it the same?
- What totally new concepts were introduced and how were they applied?
- Where does this material "fit" within the overall structure of the course?

- Stop periodically and recall the material that you have read.
- Review prerequisite material, if necessary.

### Problem Solving

Solving problems is usually the most important aspect of math or science courses. You must, therefore, spend much of your study time either working or studying problems. When working a problem, follow these steps:

- Read through the problem at a moderate speed to get an overview of the problem.
- Read through the problem again for the purpose of finding out what the problem is asking for (your unknown). Be able to state this in your own words.
- If appropriate, draw a diagram and label the givens.
- Read each phrase of the problem and write down (symbolically or otherwise) all information that is given.
- Devise a tentative plan to solve the problem by using one or more of the following tactics:
- Form relationships among all facts given. (Write an equation that includes your unknown.)
- Think of every formula or definition that might be relevant to the problem.
- Work backwards; ask yourself, "What do I need to know in order to get the answer?"
- Relate the problem to a similar example from your textbook or notes.
- Solve a simpler case of the problem using extremely large or small numbers; then follow your example as if it is an example from the text.
- Break the problem into simpler problems. Work part of the problem and see if it relates to the whole.
- Guess an answer and then try to check it to see if it's correct. The method you use to check your answer may suggest a possible plan.
- If you are making no progress, take a break and return to the problem later.

- Once you have a plan, carry it out. If it doesn't work, try another plan.
- Check your solution.
- Check to see if the answer is in the proper form.
- Insert your answer back into the problem.
- Make sure your answer is "reasonable."

During the problem solving process, it is often helpful to say out loud all of the things you are thinking. This verbalization process can help lead you to a solution.

### Problem Analysis

After you have worked a problem, analyze it. This can help sharpen your understanding of the problem as well as aid you when working future problems.

- Focus on the processes used (not the answer) and ask yourself these questions:
- What concept, formulas, and rules did I apply?
- What methods did I use?
- How did I begin?
- How does the solution compare with worked examples from the textbook or my notes?
- Can I do this problem another way? Can I simplify what I did?

- Explain each step using your own words. Write these explanations on your paper.

Important: The knowledge of most math/science courses is cumulative. Many concepts build on previous concepts, and a poor understanding of one concept will likely lead to a poor understanding of future concepts. Consequently, you should seek help early, if you encounter difficulty.
