Technology is a means to an end.
It can be a monetary black hole, but it helps us implement teaching strategies that are substantially different from the traditional methods of teaching introductory physics. When I say traditional strategies, I mean the talking head lecture with a few demonstrations, combined with a confirmation-based laboratory in which students are told to make certain measurements and try to get the right number. The problem with those strategies is we just don't believe they work. Our students could give answers to problems they'd seen before, but they could not solve new, sometimes even slightly different problems. Our introductory-level physics course, however, serves everybody who needs introductory physics.
