I have gathered all my HOW TO articles in one place. In the exploratory spirit of this blog, I have tried a new tool called mentormob:
Mentormob is a good way of making a playlist of your students creations, or asking them to collect a playlist of articles, videos etc. for research purposes. I also recall an English lesson plan for Catcher in the Rye where the students were asked to make a playlist for Holden. They had to choose a song and then say why they chose that song. Mentormob allows you to write a description for each post as well as upload documents.
And it works great on the iPad!
Note: it is not an app though- you must access it through Safari.
