Graphing calculators facilitate learners' ability to build cognitive links between mathematical representations by providing quick access to multiple representations. This exploratory study investigated the effects of technology-enhanced instruction on student achievement, perceptions of technology use during instruction, problem-solving success,…

Manipulatives have been used in many mathematics classrooms across many age groups with the aim of helping students to understand abstract concepts through concrete, kinesthetic, and visual experiences. In this paper, after we provide a background for the use of physical and virtual manipulatives in teaching and learning of mathematics, we will…

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…

This 2-year study involved 580 seventh- and eighth-grade students to determine the effects of a long-term professional development plan to integrate the Texas Instruments' Math Explorer calculators into mathematics teaching and learning and students', teachers', and parents' attitudes toward calculator use. Includes recommendations for practice…
