An evolving resource for iPad apps for language learning and teaching that can be easily searched and browsed by skill, type of collaboration possible, and cognitive level (based on Bloom’s taxonomy, terms from www.usi.edu/distance/bdt.htm). Limitations are listed in the comments. The tag "Collaborate" means that users can work together to create something. An example of a tool that allows collaboration is a wiki. The tag "Comment" means that users can leave comments on others' work. An example of a tool that allows commenting is VoiceThread.
