My Take
This site has GREAT information, and a lot of it. It is set up topic specific and very easy to navigate. Some videos are a little long at 18-19 minutes.
How I Use It
I have been using this in my blended learning AP Biology classroom. I will have students watch different segments at home and have a class discussion the next day. My students will also use this as a review tool. I don't spend time in class reviewing so this is one tool that my students do use.
