classroom observation debacle

Well, it all started out great. I created an online survey which I sent to every teacher in my fieldwork school. I got 23 responses- which I was very happy about. I compiled the data, and because it was so statistic heavy, thought powerpoint would be the best way to go so I could use all of their chart and graph templates. I learned A LOT--I had previously only known how to use powerpoint in the most rudimentary way, and I do see TONS of applications for it in direct instruction/lecture portions of a curriculum. I'm pretty proud of the visuals I created. I know for some of you it's old news, but as the name of this blog suggests--this old dog is late to the game. But better late than never...
The problems came in when my husband informed me that there would likely be compatibility issues between the Mac and Windows versions of the program, and as usual, he was right. The problem is, he told me as I was finishing the presentation around midnight last night. (long story--blackout) I came to school this morning to see what I wound up with, and I'm basically rebuilding the slide show all over again--cutting out of another class to do so. And I lost the sound file completely, despite sending it 3 different ways. Yes, this is all part of technology, and because most schools have Windows and my home pc is a Mac, it's a problem I better get used to dealing with. Still, I'm feeling incredibly frustrated and upset right now. Just needing to vent...
