Most material is soon forgotten

Review makes a big difference


An overall approach to aiding review:


  • material is available in small rich chunks
  • the learner can search
    • in class material
    • all material ...
  • the learner can mark material to revisit

Much better than lectures which are gone save for a few hasty notes.  

Richer and more accessible than books.

Much better than videos.  Even if you change the playback speed it is still the same material in the lecturer's order at the lecturer's pace.
