Why Underlining And Marking Work

  1. Marking forces you to sift through what you have read in order to identify important information. This helps keep your mind on what you are doing.

  2. Marking keeps you physically active while you are reading. This helps to direct your concentration to what you are reading.

  3. When you are marking, you must evaluate what you read to decide whether or not to underline it.

  4. Marking helps you see the organization of facts and ideas.

  5. Marking demonstrates whether you have understood a passage you have just read. If you have difficulty marking, you will know that you did not understand the passage.

The following example illustrates how one student underlined a passage from an economics textbook. Notice the additional markings in the left margin.
