Describes a spreadsheet model for approximating square roots then extends that model into the intriguing domain of chaos. Focuses on the use of a dynamic model to promote habits of mathematical reasoning, conjecturing, and graphing analysis that support mathematics learning across grade levels. (ASK)

Spreadsheets have become popular tools for exploring mathematical patterns and building conceptual understanding of variables and functional relationships. Presents examples of students' work to illustrate multiple paths of inquiry, generalization, and mathematical reasoning. Supports effective investigation of patterns and functions for students…

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)
