|Abstract:||A common dilemma in educational technology is designing the optimal level and type of guidance to support open-ended learning activities. We explored this question by designing a computer-based coach for Invention activities – a form of ill-structured problem-solving followed by expository instruction. The Coach was designed to elicit the core learning mechanisms of Invention by problematizing students’ solutions and mimicking naturalistic teacher guidance. This research tests both the efficacy of our designed guidance and the appropriate amount of guidance for Invention activities. In an experimental study, 205 middle schoolers worked with full, minimal, or no guidance versions of the Coach before receiving a lecture on the target knowledge (ratio structures in science). Students who received the full guidance Coach were better able to transfer their knowledge to novel domains. The work has implications for the design of guidance in open-ended learning environments.|
