Teacher Tube - Copyright Assignment

1) The first video I watched for our Copyright Assignment was a video put together by a teacher named Ms. Latham (I didn't even notice the name until I was halfway through the video - It was purely a coincidence, I assure you :) ). Ms. Latham introduced her students to their poetry unit with a video in which she read a poem entitled "What We Believe" by Anita Endrezze. Her recorded voice accompanied the images on her slideshow.

Ms. Latham introduced the poem by sharing with her students (and any other viewers) the title and author of the poem - giving full credit. She only used one poem from this author, so she seems to be staying in the guidelines. To introduce poetry and the specific poem, she read from their class text book. If the poem she used was also from their text book, she is not violating any copyright laws. The only question I had was regarding the images she used. It appeared to me as if they had been taken from the internet, yet other than one or two exceptions (in which the site was "printed" on the picture itself), I didn't see these images cited.

2) The second video I watched was a teacher that put a humorous video together to welcome his students back after the summer break. He uses clips from what appears to be many different sources.

From what I can tell, he does well abiding by the copyright Fair Use policies. He plays short clips from different sources and he cites all of his sources at the end of the video.
