Communication and Extension Education: Process, Methods and Adoption
What the exam tests
Communication and Extension Education tests the communication model, barriers, extension principles, teaching methods and adoption of innovations.
Core rules
- Communication elements: sender, message, channel, receiver, feedback and noise. Types: verbal and nonverbal; formal and informal; interpersonal and mass.
- Barriers: physical, semantic, psychological, cultural and organizational.
- Extension education is out-of-school, voluntary, practical and community-based; it is not formal schooling.
- Methods: individual (home or farm visit, phone call), group (demonstration, meeting, exhibition; method demonstration versus result demonstration), mass (radio, TV, print, social media).
- Diffusion of innovation: innovation, communication channels, time and social system. Adoption stages: awareness → interest → evaluation → trial → adoption.
- Audio-visual aids should match the audience, message and setting; too many aids distract.
Worked example
A worker must teach handwashing to mothers in a village with low literacy. Reasoning: a group demonstration with a basin, soap and a mother volunteer allows observation and practice; a lecture alone is weaker. A poster can reinforce, but it cannot replace practice. If the audience is scattered, a mass medium plus a follow-up group session works better. The choice is justified by literacy, participation and reinforcement.
Traps
- Calling extension education formal education.
- Confusing a method (demonstration) with an aid (chart).
- Reversing adoption stages.
- Choosing a channel without audience analysis.
