I love reviews like this. My original intent in college was to be a middle or secondary science/math teacher. To find someone who captures the enthusiasm within himself and transfer it to his students is what I wish my grandchildren (okay I'm not 21 anyomre) will find. Excellent article and very well written.
Mike, thank you for your comments. The PST has made teaching astronomy in the daytime much more enjoyable. I've enclosed a recent picture of part of my smallest class huddled around the piggybacked PST and the TV monitor we use.
