I have to be honest. I don't check the copyright guidelines as closely as I should when I take things from the internet. I have always paid attention to the "cc" when making paper copies to use in the classroom, but the internet is so loaded with immediate clips for use, etc., that I don't look for the copyright guidelines. Watching the video clips makes me more aware of looking out for the "cc" as I prepare presentations for staff development sessions. How does all this apply when you are giving a presentation? Sometimes, a clip I find can add clarity or inspiration to a presentation and I just need it to fit. I can't really say for sure if I have broken copyright guidelines or not while using internet resources, but I can tell you that I will pay closer attention in the future.
