The SQ3R Reading Method is a reading comprehension method named for its five steps: survey, question, read, recite, and review. It is a useful method for retaining more information when reading books or articles.
Survey -- Look over the text and pay attention to titles, summaries, headings, captions, graphs, diagrams, bold print, italicized words, images, and other important information related to the structure of the text. With advance knowledge of what information the text contains, you will be better focused when reading.
Question -- Come up with questions about the content as you survey the various sections of the text, and write them down. When formulating your question use terms such as who, what, where, when, why, how, compare, contrast, describe, explain, list and trace.
Read -- Actively look for answers to your questions as you read the text.
Recite -- Answer the questions out loud (or on paper) in your own words. Are you able to answer in your own words? If not, re-read the section again and formulate another response to the question. You may want to revise your question, now that you are more familiar with the topic.
Review -- Reread your notes, highlight, take additional notes, or ask more questions.
