True, but software isn't going to solve that. (Note: I am a classroom teacher.)

Teacher to student lecturing happens for a combination of three reasons:

1. The teacher believes it's the best way to present the material.

2. Generally, a lecture is easier to prepare (and easier to keep on task) than any other form of instruction.

3. To the average person (and many administrators) a classroom full of children sitting silently in rows, all taking notes, looks "right".
