It is widely agreed that a conceptual understanding of engineering concepts is a required compliment to a technical understanding of the equations and how to solve them. However, students often enter our classrooms with misconceptions about fundamental phenomena, presenting a significant obstacle to conceptual learning. The first part of our work consisted of establishing reliability of instruments to assess conceptual understanding. In the present study, we share results from multi-‐institution concept inventory assessments in heat transfer and thermodynamics. Our results indicate that instruction typically improves students’ conceptual understanding in these areas, but not typically to “proficient” levels (concept inventory scores over 70%). However, after implementation of inquiry-‐based activities, scores improve significantly, both with respect to the pre-‐course concept inventory scores and with respect to post-‐course scores for students who do not perform these activities.
