By taking into consideration the significance of the socio-economic contexts, this research investigates teachers' perceptions of the role of graphing calculators, as mediating tools, to help facilitate mathematics instruction of students from two different SES backgrounds. The main source of data are in-depth semi-structured interviews with four teachers, two from each SES school. In general, the participants' perceptions of the role of the graphing calculator were dependent on the context within which it was used. Also, the participants played a crucial role in determining the nature of graphing calculator use with the low-SES school's participants appearing not to involve their students in lessons that capitalized on the powerful characteristics of graphing calculators. To tease out the role of the situation context, a four-component framework was conceptualized consisting of teacher, student, subject matter, and graphing calculator use. The components of the framework were taken to be continuously in interaction with one another implying that a change or perturbation in one of the components affected all the other components. The continuous interactions of the components of this framework suggest that equity issues in connection to the nature of graphing calculator use should be an ongoing process that is continuously locating strategies that will afford all students appropriate access and use of graphing calculators.

Using activities to create and collect data is not a new idea. Teachers have been incorporating real-world data into their classes since at least the advent of the graphing calculator. Plenty of data collection activities and data sets exist, and the graphing calculator has made modeling data much easier. However, the authors were in search of a better physical model for a quadratic. We wanted students to see an actual parabola take shape in real time and then explore its characteristics, but we could not find such a hands-on model.
