A review of literature concerning teaching-learning media and the factors that influence the choice of teaching-learning media was conducted, in order to establish which teaching-learning media teachers are using to present a lesson, especially in OBE. The classification of teaching-learning media by different media specialists was looked into, before it was applied in a Biology lesson. The plant cell and animal cell sketches were used as examples to draw up transparencies, overlay-transparencies and to build models. An empirical investigation was undertaken to investigate which teaching-learning media teachers are using and why they are using certain teaching-learning media. It also investigated the role teaching-learning media plays in presenting a lesson and what can be done to help teachers to use more effective teaching-learning media in teaching Biology as part of Natural Science in the senior phase of OBE. According to the investigation teachers seem to stay with the traditional teaching-learning media, such as the chalkboard and textbook, for they are easily available, user-friendly and cost saving. However, there is a need that more courses should be offered, where teachers can be trained how to use certain teaching-learning media and how to create their own teaching-learning media. / Thesis (M.Ed.)--North-West University, Potchefstroom Campus, 2005.
