Teach students that there are five kinds of concept maps: Spider Maps (similar to mind maps, spider maps start with a single topic at the center and then split into subtopics organized around the center), Flowcharts, Hierarchical Maps or Chronological Maps, and System Maps. Help students understand when each type might be helpful.
Teach students how to use a timeline (and when it might be helpful).
Teach students how to outline information. Many students do NOT know how to create order out of their notes and therefore struggle when they study their notes.
