The Logo Action Research Collaborative is creating a professional development program in the Newton (Massachusetts) schools which is based on action research and designed to support teachers and improve the use of Logo computer-assisted instruction in their classrooms. During the 1 year workshop, teachers work collaboratively on Logo programming projects, learn to define research questions, and identify ways to gather data that fit in with their teaching approaches. Teachers keep journals in which they write down classroom observations, and these are analyzed together with samples of student work. Through direct involvement in research teachers gain insights about the teaching and learning in their own classrooms, and, at the same time, come to recognize and respect their own and their colleagues' ideas. In addition to developing a set of materials and activities to support experienced Logo teachers in carrying out action research activities with a focus on Logo learning, the Logo Action Research Collaborative is supporting school district personnel in leading research meetings with teachers in their own districts.
