A model for learning mathematics is proposed which involves the components of using, discriminating, generalizing, and synthesizing. The ways pupils use Logo programs as tools within their projects and how the nature of their programming tools become more explicitly understood and generalized are discussed. (RH)

Reports results of a four-year experiment integrating writing into secondary mathematics classrooms. Discusses (1) the development of a pedagogical model for mathematics journal keeping; and (2) the practicalities of implementing journal writing in the curriculum. Includes sample journal entries.
