What are the benefits of taking textbook notes? Taking notes based on the textbook obviously helps to organize and summarize info in the textbook. But if I highlighted the most important areas of the textbook, and while revising I only look at these parts, won't it have the same effect as taking textbook notes (as far as summarizing goes)? Ultimately my question is, for students who have achieved good grades by taking textbook notes, what are the benefits of doing it and why is it better than just reading the important parts of the textbook?
In addition to the benefits mentioned by fgysin, you might want to include in your notes information that is not explicitly in the textbook, for example alternative ways to think about some of the textbook's material, details that are omitted in the textbook, special cases of the facts in the book, or connections between different passages in the book.
