California school districts needing to write or update their Tech Plans will have a new requirement:

include a component to educate pupils and teachers on
          ethical behavior in the use of information technology, the
          concept, purpose and significance of a copyright, and the
          implications of illegal peer-to-peer network file sharing.

AB 307 has also been amended to include Internet safety.    I think it’s very possible that this requirement will encourage teachers to include Web 2.0 tools in their curriculum. Seems logical to explore lessons on how students may use Web 2.0 tools safely and ethically in addition to the cautions and legal aspects, no?
