Five prescriptions for evangelism are offered from five different schools of thought in educational psychology. Since understanding and the integration of truth are a central theme in evangelism, how do humans process truth? This paper constructs hypothetical evangelistic scenarios according to behaviorist, cognitive processing, interactivist, biological, and constructivist theories of learning. It asks which model best represents how evangelism ought to be conducted. Contains 4 figures and 12 references. (Author/BT)
