Michael, Right. And even without technolgy as a factor, dry and boring is difficult to tolerate for very long by nearly anyone. Engagement and student participation are enhanced when senses are incorporated into the lessons, especially when they facilitate the learning (and are not the focus). Stopping a lecture to trace a figure from their textbook will be a long remembered visualization. In this example the focus is on the drawing, not that the sense of touch, vision, pressure, thinking, and motion were involved in the process. Barry Westling
