Many students have difficulties in interpreting position versus time graphs. Presents an activity involving calculator-based motion labs that allows students to bring these graphs to life by turning their own motion into a graph that can be analyzed, investigated, and interpreted in terms of how they actually moved. (ASK)

Investigates secondary mathematics teachers' use of the graphing calculator in their classrooms. Examines whether algebra teachers are currently using this technology in their classrooms, their perceptions toward the technology, and any changes in the curriculum or instructional practices. Indicates that the use of the graphing calculator is still…

Presents the effects of a project focused on calculator use in middle grade mathematics and compares teachers' beliefs about calculator use before the project to their beliefs two years after participating in the project. Indicates that teachers did not significantly change their beliefs about calculators over time. Contains 23 references. (ASK)
