Improving Students’ Van Hiele Level Of Geometric Thinking Using Geometer’s Sketchpad

Abstract

The objective of this study was to examine the use of the Geometer’s Sketchpad on students’ van Hiele level of geometric thinking. A total of 31 Year Three students from a primary school in Pahang, Malaysia, participated in this study which was carried out over two weeks. The experimental group (N=16) was given the intervention using Geometer’s Sketchpadfor six lessons while the control group (N=15) was taught using the traditional approach of chalk and talk. Quantitative data of the study were obtained through pre and post tests. A questionnaire was also used in this study. Paired samples t-test results indicated that the improvement of van Hiele level of geometric thinking for both the students in the experimental group and control group between all the pre and posttests is significant at the level of . However, the difference of van Hiele level of geometric thinking between students in the experimental group and in the control group were not significant for the postests. The study also found that there was no correlation between students’ literacy in using Information and Communications Technology (ICT) and their van Hielelevel of geometric thinking after using Geometer’s Sketchpad.
