Effectiveness of the developmental supervision model as a tool for improving quality of teaching : perceptions of the South African primary school-based managers and educators

摘要

Many schools in South Africa face challenges of poor teacher performance as a result of implementing performance evaluation systems that are not developmental. In an attempt to resolve the current implementation challenges of the South African Integrated Quality Management System (IQMS) which is theoretically aligned to the TQM principles, the focus in this study is on the perceptions of school-based managers and educators regarding the effectiveness of the developmental supervision model as a possible tool for improving the quality of teaching.A mixed methods research design characterised by the explanatory sequential design was used to address the research questions. Out of the 350 randomly selected participants in all 15 districts of the Gauteng Province responded to the quantitative phase in the form of questionnaires. This was followed by analysis of the qualitative data from three focus group interview sessions that were conducted in Sedibeng East, Sedibeng West and Johannesburg North districts of the Gauteng Province in order to get in-depth explanations on perceptions of school-based managers and educators. Each of the three focus group interviews comprised of ten purposefully selected participants embracing two principals, two vice principals, two HODs and four educators per district.The results indicate that school-based managers and educators strongly believed that the developmental supervision model is an excellent tool for improving quality of teaching by applying implementation strategies comprising of the clinical supervision, self-directed supervision, peer supervision and connoisseurship strategies. These results were based on the opinion of the participants that the characteristics of the developmental supervision implementation strategies align with the Total Quality Management principles which were perceived to have a positive influence on improving the quality of teaching. The same supervision strategies were also found to match different levels of teacher development according to their levels of expertise and commitment. In contrast, the IQMS performance evaluation process, which also involves self-evaluation and peer evaluation, was believed to lack compliance with the developmental supervision strategies and the TQM principles during practical implementation because of characteristics related to the traditional inspection approaches to professional development. It is therefore recommended that the developmental supervision model should be introduced in South African schools to effectively implement the IQMS in order to ensure improved quality of teaching.
