outline maclean wesley s model of communication. point out four merits and demerit of maclean model in extension delivery
Maclean and Wesley's model of communication is based on the premise that effective communication involves a cyclical process of encoding, transmitting, receiving, and decoding messages. The model consists of three main components: the sender, the message, and the receiver. The sender encodes a message and transmits it through a channel to the receiver, who then decodes the message and provides feedback to the sender. This process of communication is ongoing and dynamic, with each component influencing the others.
Merits of Maclean and Wesley's model of communication in extension delivery:
1. Provides a clear framework: The model provides a structured framework for understanding the communication process, including the roles of the sender, message, channel, and receiver.
2. Emphasizes feedback: The model highlights the importance of feedback in the communication process, allowing for the sender to adjust their message based on the receiver's response.
3. Interactive nature: The model recognizes that communication is a two-way process, with both the sender and receiver playing active roles in the exchange of messages.
4. Applicability to extension delivery: The model can be applied to extension delivery by helping extension workers effectively communicate with farmers, researchers, policymakers, and other stakeholders in the agricultural sector.
Demerits of Maclean and Wesley's model of communication in extension delivery:
1. Oversimplification: The model may oversimplify the complex nature of communication, failing to account for other factors such as cultural differences, power dynamics, and non-verbal cues.
2. Linear approach: The model presents communication as a linear process, which may not accurately capture the dynamic and iterative nature of real-world communication interactions.
3. Limited focus on context: The model focuses primarily on the sender, message, and receiver, neglecting the broader social, political, and environmental contexts that can influence communication outcomes.
4. Lack of emphasis on technology: The model does not adequately address the role of technology in modern communication, such as the use of social media, digital platforms, and mobile devices in extension delivery.
