| Abstract: | Evidence is presented indicating that spontaneously generated analogies can play a significant role in expert problem solving. Since not all analogies are valid, it is important for the subject to have a way to evaluate their validity. In particular, this paper focuses on an evaluation strategy called bridging that has been observed in solutions to both science and mathematics problems. Spontaneous analogies have also been documented in the problem solving of students. The shared natural use of analogies for unfamiliar problems is an expert‐novice similarity. Some of the strategies observed in experts were incorporated in a teaching technique for dealing with students’ preconceptions in mechanics. Students taught via these units achieved large gain differences over control groups. Thus non‐deductive reasoning strategies used by experts can give us valuable clues concerning instructional strategies for science students. This complements the prior focus in the literature on expert novice differences with a focus on expert novice similarities. |
