What is the significance of network technology in supporting teachers as they think about changing the way they teach? This simple question has been at the heart of the development of professional development activities in the Science Learning Network project. What are some lessons we have learned? * establishment of a local area network in a whole school building where asynchronous electronic messages become part of daily school culture helps to establish an environment conducive to teacher change * the presence of electronic communication expands exponentially the opportunities for colleagues in a building to share their thoughts about pedagogy, discipline, and tupperware * teachers need resources and concrete examples of new pedagogy in action-- connection to wide area networks brings these resources and images to their desktop * mediators and intermediaries (science centers) play a crucial role in supporting teacher change and development through ongoing online nudging * online documentation (web publishing, archived e-mail, message boards, electronic portfolios), while originally envisioned as being useful to provide images of teacher change to an outside audience, is much more powerful at helping the documentor(???) reflect and crystallize in her own mind the changes that are taking place * all professional development is local (kudos to Gwen for her comments) and emanates from the pedagogical and organizational context that is unique at every school.... and of course every classroom * new leaders who moved faster in the integration of technology as support to new pedagogy are providing the authentic professional development activities everyday in their school as models and points of first contact for other teachers Teachers continue to inform us regularly about their needs and frustrations. These conversations become the basis for our joint professional development activities. Steve Baumann ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Stephen H.
