Persuasion and attitude change in science education

Many strategies used to induce the occurrence of desirable science-related beliefs, attitudes, and behaviors involve the use of persuasive messages. Science educators need to become acquainted with persuasion in the context of social influence and learning theory to be able to evaluate its usefulness in the science education milieu. Persuasion is the conscious attempt to bring about a jointly developed mental state common to both source and receiver through the use of symbolic cues, and it can be distinguished from other forms of social influence. Propaganda is a type of persuasion directed toward a mass audience. Coercion relies on reinforcement control, whereas persuasion is prompted by information. Brainwashing involves coercive techniques used to obtain cooperation and compliance. Persuasion and instruction are much alike; both require conscious cognitive activity by the recipient and involve communication which includes giving arguments and evidence for the purpose of getting someone to do something or to believe something. Persuasion research is anchored in learning theory. Early efforts were based on information processing. Studies following an information process approach focused on the effect of the variables harbored within the question “Who says what in which channel to whom with what effect?” on belief and attitude change. Cognitive processing and social exchange approaches to persuasion represent extensions to information process. Cognitive processing is concerned specifically with how people personally process the arguments presented in a persuasive message. Social exchange emphasizes the interchange that takes place between the message source and recipient. These approaches seem to be fruitful areas for future persuasion research in science education. Science educators' unfamiliarity with persuasion research stems from the fact that it is largely reported in the social psychology literature and has not been integrated into a framework familiar to educators.
