Today my students used the Promethean Activslate in a review activity. Every student was so engaged in the lesson. It was worth the time needed to make the interactive elements work together. As we closed up class, one student summed it up "What do you mean we're done, we just got started with class!" He was unaware of how much time had passed. Based on student interactions as they gave suggestions to the person using the Activslate there was a deeper understanding of the concepts. The assessment method was too informal to ensure accuracy but anecdotal evidence was stunning. Several students asked "Can we do this again next class period?" That's what makes teaching fun.
