In this study I examine the issue of how to support students' coordination of computer algebra systems (CAS) and paper-and-pencil in solving mathematics problems. Together with a classroom teacher I designed and conducted a collaborative teaching experiment in a ninth-grade algebra classroom to understand how to support students' coordination of…

The purpose of this study was to determine if the use of a graphical teaching and learning approach via the graphing calculator enhances students' understanding of the formal definition of limit. College students in six sections of Calculus I participated by completing a test prior to the introduction of the definition, and completing a second…

Reports on a research study that examined how some teachers used graphing calculators in their instruction of mathematics, and how their views of mathematics were manifested in the ways in which they chose to use this technology. Suggests that teachers used graphing technology as an extension to the way they always taught the unit. Contains 23…
