During the past few weeks (and months), I have noticed quite a buzz of tech talk going on in the department and district. Today in a meeting I saw a wiki that had been created as a working tool for a CIA summer event. Yesterday, someone wanted to know more about Web 2.0 tools. Last week, two individuals described a ning they had created for target groups of teachers. It's apparent that people in HISD are beginning to talk about and use Web 2.0 tools to engage teachers and to enhance their work. What have you recently heard or seen?
