Patricia,
Yep! Variety does keep classes more interesting. Sometimes even routine activities can involves multiple sense, For instance, taking notes. First the student listens, then writes imortant keynotes, then rewrites notes, then reads the notes into a recorder, than plays the tape back as they review the notes, then types a summary, then questions other students, then teaches other students. Writing all this makes it seem like a long and impractical experience, but I have seen extrodianary success with this method. Repitition is the key to retention.
