I found You tube to have the most things I can use and the students are already familiar with this.
Other sites I can use are MSNBC, investopedia.com, USA Today, and Fox News.
as long as students/teachers are publishing content to a secure location (walled garden, educational network or website that require passwords, etc.) they can pretty much do whatever they want – as far as creating products for instruction or to demonstrate learning. Teachers and students CANNOT copy entire works and/or scan entire collections of images or publish copyrighted materials to the general public. I did not know that if it was a secure location that you can do whatever you want.
