Use of technology in middle grade mathematics is controversial. Major policy documents have teachers torn between enthusiasm for technology-facilitated mathematical investigation and cautions about undermining students' computational skills. This article examines research concerning use of computers and calculators in mathematics at the middle…

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…

Describes and illustrates the Monomial Sums Approach, a graphical learning strategy, facilitated by microcomputer capabilities that allow easy manipulation and exploration of graphical representations of polynomial functions. Reduces emphasis on memorized rules in favor of qualitative understanding of functional behavior, visualization of…

Reports on the results of a project that involved experienced K-12 teachers in mathematical modeling, using variables and functions in a fundamental and intuitive context, while investigating the appropriateness of spreadsheet solution methods across a broad range of grade levels.
