4. Be OCD About Your Notes
The more OCD you are about organizing your notes, the better. The Journal of Reading compared different note-taking methods and found that the most rigorously structured-those with hierarchal ordering and numbered subsections-were of the highest quality and accuracy. A two-column method came in a close second; these notes were arranged such that the left column contained the information from the given event (i.e. the meeting, lecture or talk) and the right column was used later to fill out follow-up points and highlight key themes. Although these notes were significantly more precise than freestyle note-taking, there was little difference in the ability of the note-taker to recall the material.
5. Draw Pictures!
The British Journal of Educational Technology found mind-mapping to be significantly more effective than just writing out notes. Mind-mapping brings visual structure to notes, usually involving writing one word in the center and drawing offshoots from it with related ideas and phrases. Researchers studying two groups of note-takers, those using the SmartWisdom method (a popular alternative mind-mapping system) and those writing traditional notes found that although there was no difference in the accuracy of the notes, the mind-mappers were able to present the information back with more clarity and coherence than their counterparts.
