Being a middle school math teacher, I use Learn Zillion and Khan Academy as supplementary material. My students can access these two websites from home, if they need to review concepts. I realize that these two websites are not synchronous learning environments, but at the middle school age they do help with students learning and provide a limited experience with on-line learning.
As I reviewed the different synchronous delivery methods, I think the Big Blue Button has more features for classroom learning. Teachers can use their whiteboards, there is a microphone feature, and a virtual chat room. I really like that teachers can have a private chat with a student. This can be very beneficial in a math class when a student is not applying a concept correctly and only the teacher and student can see what is posted.
Other delivery methods:
- Adobe Connect This option enable instant access and cross-mobile device or firewall collaboration from virtually anywhere.
- Cisco Webex- Allows interactive classes and training online, with video, breakout sessions, and hands-on learning labs. It allows up to 1,000 participants per session.
- GoToMeeting- Allows interaction with students anywhere in the world. It can be access from any mobile device, and allows conferences of up to three people.
- Google+Hangouts- Allows to share information, graphics, photos, and group conversations.
