Note-taking is effective for learning because it engages the brain in active processing of information. By summarizing, paraphrasing, and categorizing information, note-takers are doing much more than just passively recording—they are actively engaging with the material, which enhances understanding and retention. Cognitive science research suggests that this process improves memory recall and conceptual understanding by creating mental connections and pathways. Moreover, notes serve as a useful resource for review and revision, aiding in long-term retention of the information.
