This paper offers a review of the origins, design strategy and implementation plans of the Teacher Education in Sub-Saharan Africa (TESSA) research and development programme. The programme is working to develop new models of teacher education, particularly school based training, including the creation of a programme webspace and an extensive bank of Open Educational Resources. This paper identifies key research findings and literature which informed the TESSA approach and activity design. Drawing on participant experiences in different development activities and data generated in development testing activities, I offer a personal account of the programme to date. The paper concludes by suggesting a pattern of resource making and design that could be adopted by other programmes serving parallel development needs. (Contains 9 footnotes.)
