Re using You Tube clips in presentations

IMHO it is a really good idea to save the video in some way if you are using it in a presentation. If you save just the link and use the Internet to access it, one day that clip may be removed, or the Internet could be down that day. If you save the clip to a hard disk or a flash RAM that will save the day. Embedding a video also removes the comments. Sometimes people leave objectionable comments. A further advantage of saving a video clip is it is not always desirable for parents to know exactly where you got the clip from.

There have been a few presentations in another class. These were all edible prizes, I am all for that naturally. Stickers work well also and may just be better for the students health and the teachers wallet. One school in Taipei used slips of paper with the word prize printed on it. If the students were good they got a "prize" if they were bad they lost a prize. The students treasured these prize slips, so they were working at a fraction of the price of candies.
