How I Use It
I use the more interesting videos (such as "doodling in math") to build interest or as a reward for good behavior during learning. I also assign students tutorial videos if they need to learn alone for various reasons, and then we review afterward to clear up whatever they didn't grasp. I love that videos can be downloaded on their ipad app, so I can use it in the classroom with no internet access.
It's rare to find so much material offered for free on such an accessible platform. The lesson videos are good for students who miss a lesson, flipped learning, or those who need extra instruction or review. The narration is not super exciting, but has a bit of personality instead of being just dry information. Favorite part: There are some lessons on less-traditional topics that get students engaged in unexpected ways, e.g. the "Doodling in Math" series which made my math-averse students light up in math class!
