Fair Use & TPAK

I learned a lot about fair use. I am glad that I now know the rule about 60 seconds for video and 30 seconds for audio. The question about the 9/11 footage threw me off at first on the quiz. I find it interesting that the footage is good only up to 10 days after the event. I am glad that we have fair use as a teacher, this can help lessons to be more effective. TPAK stands for technological pedagogical content knowledge. TPAK is the intesection of content knowledge, techological knowledge, and pedagogical knowledge. I think that it would be important to use TPAK in teaching so that the students will get to use all 3 knowledges.
