"MentorMob becomes truly innovative, and appealing to educators, in the fact that the curated collections take the form of "Learning Playlists." These playlists allow users to sequence the resources they are gathering so that, rather than a random assemblage of information, learners are presented with a logical progression of steps that helps them effectively learn the concept, skill, or process that they have come to MentorMob to find out about. Essentially, by relying on a community-based, crowdsourced approach to developing instruction, MentorMob facilitates an effective and efficient way for visitors to the site to learn just about anything."
A great post by Dr Justin Marquis in which he beautifully positions the usefulness of "Learning Playlists" for students.
