This is a jam-packed thirty-nine minutes, where we explore the power of tagging, teachers using tumblogs, mathcasts, VoiceThreads in health, speech, history, math, music, technology, and EFL classes. Join Paul Allison, Lee Baber, Susan Ettenheim, and VoiceThread's Ben Papell (Yes, he's a "regular" by now), as they welcome these fresh voices, fresh at least to us at Teachers Teaching Teachers:

• Carla Raguseo, an EFL teacher and Computer Lab coordinator at A.R.I.C.A.N.A., a Binational Center in Rosario, Argentina
• Carla Arena, a Brazilian EFL teacher, teacher trainer and site content manager at A Binational Center in Brasilia, but she's on a leave right now.
• Jeremy Brown, a Special Education Teacher at the Medow Hall Elementary School in Montgomery County, Maryland
• Judi Epcke, a teacher and Technology Integration Specialist in Northbrook, Illinois
• Tim Fahlberg, founder of Mathcasts, after 11 years as a math teacher.

Some educators, including some of us who meet regularly on Teachers Teaching Teachers, have begun to find places in our curriculum for microblogging.

“Compared to regular blogging, microblogging fulfills a need for an even faster mode of communication. By encouraging shorter posts, it lowers users’ requirement of time and thought investment for content generation. This is also one of its main differentiating factors from blogging in general. The second important difference is the frequency of update. On average, a prolific blogger may update her blog once every few days; on the other hand a microblogger may post several updates in a single day.” (Java Akshay, Tim Finin, Xaiodan Song, Bell Tseng, Why We Twitter: Understanding Microblogging Usage and Communitites.
