This article examines three important facets of the incorporation of new technologies into educational practice, focusing on emergent usages of the mathematical tools of computer algebra and dynamic geometry. First, it illustrates the interpretative flexibility of these tools, highlighting important differences in ways of conceptualizing and…

Discusses the role of microworlds in micro and macro educational systems. Topics include epistemological concepts; educational innovations; mathematics education in elementary schools; microworlds as simplified reality and as mental structure; and a three-stage theory of the development of learning. (LRW)

Explores the strategies and interactions of elementary school children in a computer-based microworld related to the concept of length. Included both on and off computer activities that contributed to the collaborative learning environment, a high level of interest, and enthusiasm for mathematical activities. (Author/LRW)

Describes the design principles behind a set of research-based software microworlds included in the "Building Blocks" program, a pre-kindergarten to grade 2 software-based mathematics curriculum. Discusses how to help children extend and mathematize their everyday activities and presents the nine-step design process model used.…

Explains TIMA (Tools for Interactive Mathematical Activity), that were designed to provide elementary schools children with contexts in which they could enact mathematical operations. Discusses differences from drill and practice software; provides examples of how the TIMA were used by children to engage in cognitive play; and emphasizes the…

Discusses improving mathematical reasoning through the design of computer microworlds and evaluates a computer-based learning environment that uses multiple representations to improve undergraduate students' conception of average speed. Describes improvement of students' estimates of average speed by using visual feedback from a simulation.…

Analyzes, as a function of grade level, the representation of gender, competition, and violence in 17 top-selling software programs designed for mathematics education. Results indicate that mean percentages of violence, competition against the program and competition against a peer increase across grade level; mean percentages of female characters…

A study of 50 students (grade 9) enrolled in a computer course found that home computer access for females was a predictor of early success for using computers as a learning resource and that enrollment in a computer course was greater for females who had access to home computers. Initial advantages diminished with continued use of computers. (PEN)
