I learned about MentorMob over the summer and have been playing around with their platform a bit. MentorMob allows you to create learning playlists, for free, which can be used for your class or for an individual student. These learning playlists can be a compilation of video, online content, articles, and uploaded documents. As a teacher, you add material to the playlist, and then share the link (or embed the playlist) with a student or a class.
In the math department at my school, we have been talking a lot about how our Academic Center can best be used to support students struggling in our classes. We have been discussing compiling Khan Academy/YouTube videos and problem sets available online specific to a student’s needs. I think that MentorMob might be the perfect tool for us to use to create a customized learning playlist for the student. Below is a video I put together for teachers at my school to explain how we might be able to use MentorMob. Feel free to leave thoughts in the comments.

Love the way you’re using MentorMob as an curation tool to organize other resources (like Khan Academy). If you ever have any feedback or questions, you can always give me a holler!
