Computer Simulation: Engaging Preservice Mathematics Teachers in In-depth Investigations of a “Simply Complex” Problem
Society for Information Technology & Teacher Education International Conference 2008 (Mar 03, 2008) pp. 4429–4431
While collaborating with two fourth-grade classroom teachers, I encountered a "simply complex" probability problem and used computer simulation to get the mathematical ideas to the teachers and their children. Recognizing the pedagogical value of...
Primes in context using technology: Toward a didactical model for the teaching and learning of prime numbers in middle school mathematics
(2008) pp. 1–330
This study fulfils one cycle of design research that seeks to build a didactical model for the instruction of prime numbers and related mathematical ideas in accordance with the theoretical principles of Realistic Mathematics Education. Taking the...
A Case Study of Investigating Preservice Mathematics Teachers’ Initial Use of the Next-Generation TI-Nspire Graphing Calculators with Regard to TPACK
Society for Information Technology & Teacher Education International Conference 2010 (Mar 29, 2010) pp. 3803–3810
As many researchers have studied, calculators may not be appropriate for all educational situations or all mathematical subjects. However, Ellington (2003) reported that the improvement to problem solving skills was most significant when (a) special ...
Improving Teachers’ Attitudes Toward Mathematics Teaching: Model-Centered Learning and Open-Source Learning Technology
Society for Information Technology & Teacher Education International Conference 2011 (Mar 07, 2011) pp. 180–184
Mathematical modeling was implemented in a professional development course for K-8 inservice teachers using dynamic open-source learning technology. Twenty-seven participants took the hybrid graduate course on problems solving. Data collected from...
