Final answer:
The statement is false because Cornell notes are a supplement to, not a replacement for, rereading textbook sections to fully understand and retain the material.
Step-by-step explanation:
The statement, "If you take Cornell notes, there is no need to return the textbook to reread sections," is false. While Cornell notes are a useful note-taking system to help organize and review material for writing and tests, they are not a complete substitute for the textbook. It is beneficial to read each assignment in the textbook at least twice, once before and once after it is discussed in class. Students should also consider rereading complex sections to fully absorb the material. Taking notes helps to retain information, but the textbook may still be required to clarify points or for additional study. Simply highlighting can help memorize main ideas, but to encourage critical reading and a deeper understanding of the material, notes in one's own words are recommended.
