Student performance in Mathematics and Science education is a source of concern for education authorities in South Africa. This was supported by the latest TIMSS results which were released in December 2004. As in the previous studies, TIMSS and TIMSS-R, South African learners were again outperformed by the learners of all other participating countries (Reddy, 2004). To ensure learner achievement in mathematics and science, we need committed, qualified and experienced teachers in these subjects.
In this study a holistic professional development (HPD) model was constructed, tested and evaluated using practicing Grade 10 - 12 teachers. The model developed teachers' content knowledge, teaching approaches and professional attitudes simultaneously. After analysis of the model we found that improving teachers' content knowledge builds their confidence in teaching their subject. This in turn motivates teachers to perform better in their jobs: they come to class better prepared, eager to do a job they know they are good at, no more coming late, no more plodding through uninspiring one-way lessons. They are turned into better professionals with a positive work ethic. Their improved classroom practices lead to higher enrolments of science learners and improved learner achievement, the crown of successful science teaching.
The HPD model was developed in three phases. In the first phase baseline information was obtained to determine problems that exist with the teachers' content knowledge, teaching approaches and professional attitudes. After data analysis it was found that all three of these dimensions needed development.
In the second phase the initial development of the HPD model took place. An intervention programme was structured and the effect of the programme on the teachers' content knowledge, teaching approaches and professional attitudes were analysed. Successful elements of the initial model were extracted and developed further, in addition new elements were added.
In the third phase the HPD model was developed further. Analysis of the data showed the following effect on the teachers: they were extricated from a vicious cycle where poor content knowledge leads to lack of confidence which caused unwillingness to spend time on task (poor professional attitudes, ineffective teaching approaches). Instead they became part of a virtuous circle where improved content knowledge leads to increased confidence, enjoyment and a willingness to spend more time on task (better professional attitudes and effective teaching approaches).
The HPD model was evaluated using international benchmarks, such as the Standards for Professional Development of the National Research Council of New York, USA. Recommendations and possibilities for future research are discussed. / Mathematical Sciences / D.Phil.(Mathematics, Science and Technology Education - Physics Education)
