Good comments. Eliza: I see so many college teachers and newly-graduated education majors doing exactly what you are talking about. They think that if they use Power Point (which usually prints out everything the "teacher" says), they are doing a truly amazing job. Being an old timer, like you, Eliza, I used chalk in lecture and imagination in lab -- and it works.
    Yes, I fear the right wing of education; their agendas are pretty transparent -- replace fact with fiction, ideas with dogma.
