Google Glass in currently being widely discussed in the education field for both teaching and learning. I have outlined my thoughts on the topic in the blog post here: http://blog.kathyschrock.net/2014/02/google-glass-in-class.html

Flowing are some ideas.

Students or teachers creating videos through the eyes of the wearer to share with others. These videos can be recorded and shared via YouTube as well as be shown in real-time by starting a Google Hangout.

When wearing Glass, the wearer can use both of their hands, and can easily document a science lab, presentation, or other class-related event and post that up to a class Facebook, Tumblr or Google+ account, all via Glass.

WordLens is a Glassware app that translates what the viewer is reading to and from many languages. This can be very beneficial to a second language learner in the classroom.

For students with physical handicaps, being able to search the Web via their voice as well as easily send messages to a classroom backchannel, Twitter, or the teacher, can assist them with various classroom tasks.

For students who are interested in developing applications, Google Glass provides another avenue of developing for a specialized device.
