One – way communication (Didactic method)
• Flow of communication is ‘one – way’
• Examples: lecture, television, radio
• Drawbacks:
– Knowledge is imposed (passive learning)
– Learning is authoritative
– Little participation of audience
– No feedback
– Does not influence human behavior
Two – way communication (Socratic method)
• Both the communicator and audience take part
• Audience may raise questions and add their information, ideas and opinions
• Examples: focus group discussion (FGD), panel discussion, symposium
– Active process of learning
– Democratic process of learning
– More likely to influence human behavior than one-way communication
