Describes studies of children involved in cognitive play activities using discrete and continuous computer microworlds and their transformation of these activities into independent mathematical activity. (Contains 22 references.) (MKR)

Learning environment that facilitated the acquisition and expression of procedural skills in LOGO was set up for children in the 10- to 12-year range. Ten participants were placed in a series of situations that required them to manipulate programing procedures in LOGO. Analysis of children's behavior revealed their competence in manipulating…

Described is the attempt to identify relationships between pedagogy and student behavior in a mathematical microworld. The patterns of teaching associated with LOGO-based computer activities involving ratio and proportion and the teachers role in helping students bridge the gap between LOGO- and school-mathematics practices are explored.

Presents computer approach formulated within a framework of versatile thinking designed to overcome obstacles to understanding algebra. Results from related studies comparing the computer and traditional approaches taught to 11, 12, and 13 year olds showed that the computer approach significantly improved the understanding of higher order concepts…

Described are problems of the teacher's management of computer use during the learning process and student acquisition of new knowledge that can be transferred to situations outside the software environment. Choices made to address these problems are illustrated as students learn axial symmetry using the microworld Cabri-gomtre. (MDH)
