One of my teachers has truly embraced the technology at our school and has brought me some great ideas. One of them is zondle. I had never heard of zondle, but when she showed me what it is and what it can do, I was really excited about the ways a classroom teacher could use it.
Once you create a free account (and you can also update to a premium, but the free has a lot to offer), you get a long list of things you can work with. You can create classes, add users and monitor your students.
Some of the things I like about it:
1. Sharing components- You can create content and share it with staff members in your school. Why do the work twice?
2. Teaching mode and playing mode- You can use it to both introduce the material as well as review it for "zollars" (Zondle points)
3. It's mobile! You don't have to use just a computer.
There is so much more about this, it's worth dabbling into to see what you can do with it in your classroom.
