Stylianou, Despina A.; Smith, Beverly; Kaput, James J. – Journal of Computers in Mathematics and Science Teaching, 2005
This article reports on results of an exploratory study on undergraduate pre-service teachers' understanding of graphical representations of motion functions. The study described pre-service teachers' explorations using a CBR device. Pre-service teachers' growth was studied in two dimensions: (a) in their learning of the mathematics involved and…

Hazzan, Orit; Hadar, Irit – Journal of Computers in Mathematics and Science Teaching, 2005
This article presents research on students' understanding of basic concepts in Graph Theory. Students' understanding is analyzed through the lens of the theoretical framework of reducing abstraction (Hazzan, 1999). As it turns out, in spite of the relative simplicity of the concepts that are introduced in the introductory part of a traditional…
