Developing Pre-Service Teachers’ Technological Pedagogical and Content Knowledge (TPACK) for Teaching Mathematics with the Geometer’s Sketchpad (GSP) Through Lesson Study (LS)

Chew & Lim (2013) in their journal article entitle Developing Pre-Service Teachers’ Technological Pedagogical and Content Knowledge (TPACK) for Teaching Mathematics with the Geometer’s Sketchpad (GSP) Through Lesson Study (LS) stated that there are only 26% from 151 total teachers in Malaysia who following the GSP course and only 2% who applying GSP in their teaching and learning activities. GPS itself is a software for constructing and investigating mathematical objects such as geometry, algebra, statistic and so on which can help students to learning math in easier way. In the other hands, Lesson Study is selected as one of potential ways to improve teachers’ learning and supporting to grow professionally because LS conducted by a small group of teachers meet at stipulate time to plan and observe their lesson, discuss and revise their observation collaboratively.

To develop and also to examine whether there is a significant difference in the pre-service secondary teachers’ TPACK for teaching mathematics with GSP after engaging in LS which is into the mathematics course during first semester of the 2011/2012 academic session in a Malaysian Public University, Chew & Lim are involving 46 pre-service teachers as participants and employing a one-group pre-test – post-test design as their research method and in order to get the data the applying survey and questionnaire which contain several demographic data and 7 subscale which 47 self-report items using a five-point Likert scale. After calculating and analyzing the data, can be concluded that TPACK for teaching mathematics with GSP had improved significantly after engaging LS. The difference between the mean score are statistically significant for all the subscales and overall TPACK as p < 0.5. this study also shown that LS can help the pre-service secondary teachers to develop their skill in TPACK for teaching mathematics with GSP.
