I cynically suspect that most people just cannot stand the idea that a teacher and a blackboard works better than all those technological crutches.
I remember when "educational" CD-ROMs came out for classrooms. The pitch was that at any time, a student could go look up the corresponding text on the CD-ROM.
You know, like a book.
Sigh.
Once I was at a presentation, and the presenter didn't show up. The organizer asked if anyone in the audience was willing to substitute. I raised my hand, and asked for nothing more than a whiteboard and markers.
It was the best presentation I ever did. It was a lot of fun, and the crowd was very engaged.
