Communication in extension plays an important role in technology transfer, whereas many field extension workers are poorly trained in this particular area as well as in the development of educational materials. This publication was prepared as a teaching and learning guide to be used in the pre-service and in-service education of extension staff, community development workers and all those who work and serve in rural communities. It can be considered as an ''extension methodology tool-box'' to train extension field staff in their work at the village level.
