Abstract
We developed a Web-based learning material on compliance-gaining techniques for understanding human information processing in information education. The target learners are junior and senior high school students and other young people. We aimed to facilitate learners' interest in, comprehension of, sense of usefulness in, and metacognition on the learning of human information processing through thinking compliance-gaining techniques which involve manipulation of information to make rational judgment difficult. The developed material consists of basic explanation, a short video, further explanation of psychological mechanism, and actual examples of compliance-gaining. The preliminary evaluation of the material by 24 teachers suggested the effectiveness of the material.
