M. Ed. (Science Education) / South African Life Sciences teachers have been subjected to three policy changes during the past six years. The first new curriculum was implemented in 2006, and when it was found that this curriculum lacked sufficient botany content, a new version of the curriculum was implemented in 2009. Following this, a new curriculum was being implemented in 2012 in all subjects, leaving Life Sciences teachers fatigued as a result of all the professional development workshops they had to attend each year. One principle of the new curriculum was that teachers had to use a constructivist approach to teaching, but research had found that this was not the case in South African classrooms. Furthermore, research also showed that some South African teachers lacked the necessary content and pedagogical knowledge to teach science to grade 12 learners. The aim of this study was to see whether teachers’ pedagogical content knowledge could be improved by the use of communities of practice over a period of time. The content that was focused on was DNA, protein synthesis, meiosis and genetics, as these topics were flagged as problematic topics in the National Senior Certificate examinations in 2008. A generic qualitative design was used as this research was situated in an interpretive framework. The genre of the research was phenomenology with design based elements. Before the intervention started, teachers had to complete a questionnaire and this questionnaire had to be completed again after the intervention. Interviews and feedback tools were used to obtain teachers’ views on these communities of practice. The interviews also had a section that pertained to teachers’ pedagogical content knowledge. Structured classroom observations were used to see whether teachers were implementing a constructivist approach when teaching the content. It also served as a method to ascertain whether the activities done during the community of practice sessions were implemented into classroom practice. It was found that communities of practice are an effective way of developing teachers’ pedagogical content knowledge, but that it should be continuous and would be more v effective over a longer period of time. Teachers also enjoyed these meetings, shared resources and motivated each other. Another finding of this research was that teachers did not implement a constructivist approach to their teaching as required by the new curriculum, even though they indicated that they preferred this approach to teaching. A recommendation of this research is that teachers’ professional development should take place in an informal community of practice where teachers could share ideas and resources. A keystone species is required for these communities of practice to stay sustainable. These communities of practice should be implemented on a continuous basis in order to have a positive effect on teachers’ practice.
