Why is underlining rules, formulas, and important statements in textbooks a good practice?

Highlighting or underlining rules, formulas, and important statements in textbooks creates a stronger impression because it engages the reader's focus on key concepts. This visual distinction helps in processing and retaining information more effectively. When students emphasize certain text, they are not just marking up a page; they are actively participating in the learning process.

Through this practice, the brain can more easily identify critical parts of the material, which facilitates better comprehension and recall during study sessions or exams. Even though it might also aid in memorization or group study, the primary benefit lies in the enhanced connection and engagement with the text, making it easier to revisit vital information later. Other options may seem valid, but they do not emphasize the most significant cognitive benefits of this study strategy.
