Padlet for social reading
I think Padlet is very powerful but sometimes underappreciated too. In an asynchronous course, Padlet can create a very active social space that allows students to share thoughts, ideas and even learning tools that work for them. I like the idea of having the option of staying anonymous or typing names.
