Direct linkHillman, Thomas – International Journal for Technology in Mathematics Education, 2014
This article examines mathematical activity with digital technology by tracing it from its development through its use in classrooms. Drawing on material-semiotic approaches from the field of Science and Technology Studies, it examines the visions of mathematical activity that developers had for an advanced graphing calculator. It then follows the…

Hillman, Thomas – Learning, Media and Technology, 2014
This article examines the role students play in shaping the nature of the technologies they use in their classrooms and the role teachers play in supporting students' innovative practices. Drawing on research on the sociology of technological development from the field of Science and Technology Studies, the process by which one student's…

Findings from three years of a longitudinal randomized control trial involving a national U.S. sample of Algebra 1 teachers and students are reported. The study examines the effects of a connected classroom technology (CCT) professional development and classroom intervention on student achievement when compared to classroom instruction with…

Hitt, Fernando – International Journal of Mathematical Education in Science and Technology, 2011
Mathematics education researchers are asking themselves about why technology has impacted heavily on the social environment and not in the mathematics classroom. The use of technology in the mathematics classroom has not had the expected impact, as it has been its use in everyday life (i.e. cell phone). What about teachers' opinions? Mathematics…

Lee, Jane A.; McDougall, Douglas E. – International Journal of Mathematical Education in Science and Technology, 2010
This article investigates secondary school teachers' conceptions of mathematics and their teaching practices in the use of graphing calculators in their mathematics classrooms. Case studies on three teacher participants were developed using quantitative and qualitative data that consisted of self-assessments on beliefs in mathematics,…

Kieran, Carolyn; Guzman, Jose – International Group for the Psychology of Mathematics Education, 2003
We present in this paper five case studies of instrumental genesis of number-theoretic concepts and techniques involving multiples, divisors, and numerical decomposition. The pupils, who were 12 to 15 years old, used the multi-line screen display of the graphing calculator to explore numerical tasks related to the "Five steps to zero"…
