M. Ed. / Professional Teacher Development (PTD) is an ingredient essential to the creation of effective schools, positively impacting learners’ performance and enhancing teachers’ knowledge, skills and attitudes, which are imperative in improving leaner performance. Effective PTD requires considerable time, must be well organised, be carefully structured, purposefully directed and focused on both content and pedagogy. It should be cost effective, in terms of time and effort persistent to teachers’ needs, relevant, practical and educationally sound. It is not a single stroke; one must work hard so as to attain mastery. PTD is an effective transfer of knowledge-sharing from within the institution, supporting critical junctures in its networks, ensuring integration within the externally. When carried out correctly, it is the key to ‘recharging’ teaches, giving them the tool they need. Principals are being challenged about what constitutes quality in education, and are forced to make efforts to change the status quo – instead of cocooning themselves in isolation. They have to design coherent and purposeful programmes effecting learning which is accompanied by change in behaviour, perception, thinking, beliefs, values, and awareness. It also will alter insight, and involve new patterns of operation, new strategies and new procedures. A structural PTD is determined by the specific institution’s context, helping to overcome teachers’ negative reaction to school-based PTD. They will be changed in major ways, both in terms of their teaching practices and their personal behaviour as there is no substitute for on-the-job learning with opportunities to reflect on action. One potential way to enhance PTD is to utilise constructivist strategies with the teacher. For PTD to be effective and bring improvement within the institution, the teachers should meet regularly to explore common problems and seek solutions based on shared experiences and collective wisdom. School-based PTD will cause DCS teachers to shift cultural paradigms, instil new values and goals, and help shape their professional identity, taking the microenvironment of DCS into cognisance. A good PTD needs to be mindful of connecting good theory to classroom practices, as quality PTD is the vehicle for providing the knowledge needed to support effective teaching – an adult institution. No improvement efforts can succeed in the absence of thoughtfully planned and wellimplemented PTD.
