Answer for What video conferencing solutions can you recommend for schools?

Citrix Gotomeeting has been used in some school I know as well as Skype. However, my current favourite is BlueJeans,
The BlueJeans solution offers video and audio conferencing from Windows computers and Macs as well as iPads, iPhones and android and if you dont have a computer or smart phone then you can dial into a meeting using a typical telephone for audio only conferencing.
Another advantage that BlueJeans offers is its ability to integrate into room conferencing systems such as the TelyHD which is useful when you have a room full of participants.
