Kathy Schrock's Kaffeeklatsch: Tools for Schools: Live Online Conferencing

Wednesday, February 18, 2009 Tools for Schools: Live Online Conferencing As an Adobe Education Leader, I am lucky enough to have access to a full version of Adobe Acrobat Connect Pro, a full-featured video conferencing and synchronous collaboration tool. (If anyone ever wants to see how it works, please let me know and we can set up a time for a meeting demo!) Adobe Acrobat Connect Pro is not free, and I have yet to find a no-cost option for schools that comes close to its capabilities. However, here are a few free options that provide more than just video-calling (like Skype and ooVoo). The sites listed below will allow you to experiment with a more full-featured toolset and, perhaps, provide enough justification in your school or district for the purchase of a full-fledged system! These are just brief overviews of the capabilities of each of these systems. Each system often adds new features, so take the time to give each of them a try and re-visit them regularly.

Adobe options for online conferencing; good for pandemic
