The Effectiveness of Van Hiele-Based Instruction Supported by Geometer's Sketchpad in Enhancing Student Teachers' Geometry Content Knowledge and Attitudes towards Technology Integration
2023
Overview
Regarding the role of teacher education in preparing student teachers (STs) to teach geometry to future pupils, this study investigated the effectiveness of Van Hiele-based instruction supported by Geometer's Sketchpad (GSP) to enhance STs' Geometry Content Knowledge (GCK) and attitudes towards technology integration through the one-group pretest-posttest design. Accordingly, a sample of sixty STs enrolled in the second year of the undergraduate mathematics education program at the Faculty of Education, Tanta University in Egypt, was selected. Then, the course content was arranged and taught to them through an instruction model designed based on Van Hiele's theory and supported by the GSP over eight weeks during the academic year 2021-2022, while the GCK test adapted from the TEDS-M and the scale of attitudes were applied before and after the intervention. Overall, results of paired-sample t-tests on the differences between STs' pre- and post-assessment scores indicated a significant enhancement in STs' GCK, particularly knowledge of 2-D shapes and related concepts of perimeter and area, in addition to a positive change in their attitudes towards technology integration, especially in the affective component; both with large effect size. As a result, implications for mathematics teacher educators to better prepare STs to teach geometry effectively were discussed.
