My favorite tools are the those that easily allow me to easily create movies or slideshow presentations. I can see using them to create a "How To" video on marching fundamentals. In fact, I may use my student leadership this summer to actually create the video and have it available for incoming freshmen to view.
I also like the Google Sites application. I foresee using it in my AP Music Theory class. I know that there are many websites available on music history, composers, musical instruments, etc., but I think that having the students in the class actually create a website in a collaborative effort would be very interesting and effective. I specifically would like to have a website on musical instruments (with pictures, sounds, history, etc.) and music history (different periods, music of the period, composers, etc.)
Up to now, I thought of technology in band as being limited to the use of computers for evaluation (e.g. tuning, Smartmusic, etc.) or to help with student self-recording. I see a lot more ways that I can use technology. I do have concerns about using a limited number of iPads and stations with a class size of 50+. I also still have concerns about taking away from rehearsal/practice time to incorporate new types of lessons. Much of our bands' successes come from developing technique (physical skills).
