How I Use It
My current school is very "anti" technology. Not in the sense they don't like it, but in the sense that they don't have the funding for much of it. This being said, it's been difficult for me (as a 21st century teacher) to reach my 21st century student. Recently, I was providing notes for my freshman english class. One student made a comment about how NICE it would be to have the notes of another student and could I please go make copies. Suddenly, I had an idea. I passed around a sheet of paper and had students write down their gmails. Once all students had written down their gmail, I created a google doc so that they could post their notes and share their knowledge with each other. This led to collaborative learning which I could generally facilitate (not necessarily instruct, but monitor their comments to make sure they were studying the right things). It was amazingly effective and I was excited to see my students do MUCH better on their test than they had on previous exams.
I believe that this tool can be very effective as a teaching tool. The best part of it is that students can learn without receiving direct instruction from the teacher. Meanwhile, the teacher can still monitor the learning. It could serve better if it could be reached through any email address. Many of my students don't have gmails, so if there was a similar product which did not require gmail login, I would certainly use it!
