Survey
Before you begin reading a chapter, survey the chapter as a whole. The idea is to get an overview of the materials and to see how the chapter is organized. If you look over the main ideas and structure you will be better able to comprehend the materials.
Examine the title of the chapter, the headings and the subheadings.
Preview the learning objectives and the overview at the beginning of the chapter.
Look over the figures, tables, charts, and the definitions of key words that are printed in the margins. Finally look over the summary and review at the end of the chapter. After doing this, you will have a good idea of the overall content and structure of the chapter.
Read Actively
Read Read through the chapter thoroughly. Keep the learning objectives at the beginning of the chapter in
mind when you are reading and try to answer the questions. (This will help you focus your attention on the content of the chapter.)
If you read actively you will be more involved in the materials which will increase your understanding and retention of the material.
Continue to look for answers to questions when you are reading. Some of the headings in the text are framed as questions; try to find
the answers to these questions as you read. You can also turn headings into questions for you to answer. For
example, if the heading is “Planning”, ask yourself what is planning; then look for the answer as you read the section.
Record Make records of the material in the chapter. You can highlight, underline, make notes in the
margins of the textbook, or make separate notes. Look for the main points when you highlight or
take notes. This will bring another dimension to your reading and keep the learning process active.
Try to make the most important points stand out. This will help you remember the information.
Review Read over your notes or highlighted information. Reviewing is important for retention of the material. Recite (aloud or to yourself) the highlights of what you
have read. Ask yourself questions, using questions from the book or
your own. Answer questions in your own words. You should review right after completing each
assignment and periodically to help you retain the information.
