Kathy, I think more senses, whether in study or in application in the classroom is bound to improve retention of needed material. For instance, with personal study, I suggest writing notes, then rewriting and summarizing (perhaps by word processor), the reading the notes aloud (perhaps into a tape recorder), then playing back, listening to the information while reading the notes (or just listening), then testing oneself, and then finally, testing others. Any area that falls short has just been identified as an area that still needs attention.. Repetition works well for recall information, Barry Westling
