I, like Kathleen, found it very interesting that there was such a strong emphasis classrooms combining personal computing devices and interactive whiteboards. In many schools' cases, funding these technologically advanced learning tools could be a great issue. Of course it is ideal, and there are numerous advantages that result from such great tools, but it would be extremely expensive for every classroom to be equipped with this equipment. I'm sure as technology continues to improve, these tools will become more and more common in a majority of classrooms, but in some lower income schools, desktop computers are still a rarity.
We did not have any smart boards in my high school, but my senior year calculus teacher used a tablet PC for everyday notes. That particular classroom was one of the few in the school to still have chalkboards. The tablet PC was a wonderful way for her to focus the students' attention on the lecture for the day. She also often showed illustrations of new concepts that could have been foreign if we had not seen the animations. With technology growing at the rate at which it is, I would not be surprised to see personal computing devices and interactive whiteboards become more popular. They both find great ways to improve a student's learning experience, allowing him or her to participate more, see other students' responses, and compare his or her answer to the teacher's.
