- Description
- In-service teachers’ lack of adequate instructional approaches to effectively teach geometric concepts and poor learner performance in geometry were the major rationale for this study. The preparedness of in-service mathematics teachers cannot be overlooked. The aim of this study was to develop in-service mathematics teachers’ skills for integrating GeoGebra in the teaching of geometry in a multiple case study of secondary schools in Oliver Reginald Tambo Inland district. The researcher employed ICTs in education, GeoGebra as a learning object, and in-service teachers as conceptual framework that undergirded the study. For the theoretical framework, this study utilised the Technological Pedagogical and Content Knowledge (TPACK), Constructivist Learning Theory, and the Teaching Change Frame (TCF). This study focused on the technological components of the TPACK framework, such as Technological Knowledge (TK), Technological Content Knowledge (TCK), Technological Pedagogical Knowledge (TPK) and TPACK. The researcher found that constructivism is consistent with the TPACK framework. The implementation of the TPACK was guided and assessed using the Teaching Change Frame. Regarding the methodology, the study followed the pragmatic paradigm and utilised mixed method research following the concurrent triangulation design. Due to the nature of the study, the quantitative method in this study had dominance over the qualitative method. The study was conducted in schools situated in OR Tambo Inland district in Eastern Cape Province of South Africa. Purposive sampling method was adopted to sample twelve schools, in the ratio of seven urban to five rural schools. The sample consisted of 29 secondary mathematics in-service teachers, 20 from urban schools and nine from rural schools. The TPACK questionnaire, training lesson evaluation form, observation schedule checklist and interview were used to collect data. Reliability and validity were ensured through Cronbach’s Alpha reliability test and a pilot study, whereas data trustworthiness was ensured through qualitative measures including member checking. Findings revealed that the intervention to integrate GeoGebra in geometry teaching impacted positively on in-service teachers with a highly statistically significant and a gain of medium to large effect size on pre- and post-intervention. Thus, the positive impact of using GeoGebra in geometry teaching resulted in significant differences before and after the training of in-service teachers. The findings obtained from the training showed that in-service mathematics teachers developed skills of integrating GeoGebra software in their teaching of geometry. After the training, participants felt that integrating GeoGebra in geometry teaching afforded mathematics teachers the opportunity to use learner-centred approaches, teach geometry with confidence, maintain learners’ attention and alertness in class, and improve learners’ performance. Further, findings obtained from observing participants demonstrating their experience in integrating GeoGebra showed that, not only did in-service teachers’ confidence of using GeoGebra improve significantly, but also their ability to use GeoGebra to set geometry questions. The researcher also observed that integrating GeoGebra when teaching geometry had positive effects on teachers’ understanding of geometric concepts. The findings showed significant difference in participants’ confidence in delivering lessons that can combine technology (T), geometry content (C), and pedagogical (P) knowledge. As a contribution, recent literature has been added to the existing body of knowledge in teacher education related to technology integration studies. Among them is the invention of a new teacher training model called Technology Integration Model for Teaching and Learning. Establishing a GeoGebra institute in teacher training institutions, and engaging Department of Basic Education (DBE) or provincial or district curriculum specialists to train mathematics teachers to integrate GeoGebra were recommended for policy and practice. For further research, the study recommends following-up on trained in-service teachers to track their adoption of GeoGebra in geometry teaching, learner’s performance in geometry, and their perceptions of being taught geometry using GeoGebra.
