Everyone has heard the story of the blind persons and the elephant with each describing the elephant as something different based on what parts each is able to touch. After reading the posts so far, which have been very insightful and interesting, i'm wondering if we are suffering from the same phenomena. Is the technical training to do a web page, the inclusion in an email group, the transformation from a presenter to a coach, the developemnt of attitudes and skills to be a life-long learner, etc. etc..... all part of the same formulation. Of course in the life of a teacher these all are part of the tapestry, but we may need to organize our thoughts if we are to make sense of our discussion. Perhaps the tower of Babel is a better metaphor for my being ill-at-ease with the discussion. I suggest our discussion of professional development should be focused by the need for systemic change and the need to change the whole school not just a particular exercise in a grade-level's curriculum or even of a particular teacher. What does professional development mean when we care about the education of the whole child over their whole curriculum? When we ask this question we see the need for a teacher who works as part of a team and staff, and is a part of a community, and who uses tools for problem solving and inquiry. Jim Laffey
