How I Use It
I have not used this site with students. Based on the videos, they would be OK for review, homework, extension activities.
Most of the videos are rather dated and not engaging. Any video older than 40 years will not be interesting to students. I think a YouTube search for these topics can easily find more engaging short videos. However, that takes more time than having this curated, copy-right free resource where a teacher can easily find a school-appropriate video about George Washington on Thomas Edison, for example. In conclusion, if teachers are a hurry and need something quickly for flipping the class, homework, or review, this site is OK.
