Description: The conceptual change literature indicates the presence of robust, strongly-held misconceptions in thermal science (e.g., heat transfer, fluid mechanics, thermodynamics) even after many years of formal and informal learning. For example, data collected using the Thermal and Transport concept inventory suggests that a significant number of seniors in chemical and mechanical engineering confuse the rate of energy transfer vs. the amount transferred, do not understand how temperature and energy are related, and believe that the thermal efficiency of a heat engine can be increased to 100% if all heat losses and mechanical efficiencies are eliminated. While concept inventories are one method for identifying student misconceptions, we are now exploring the development and use of a new pedagogical technique called model-eliciting activities (MEAs). MEAs were first developed to elicit problem-solving strategies from students in mathematics classes, but have now been expanded to other disciplines including ethics and engineering science2,3. Through a collaborative, large-scale National Science Foundation project, MEAs are now being developed to elicit student misconceptions about important but poorly understood concepts in thermal science. For example, misconceptions about the second law of thermodynamics and its effect on energy quality are being explored in an MEA where students estimate the overall thermal efficiency of electric vs. hybrid vs. gasoline cars. Student teams must use a systems approach and include all relevant energy conversion steps in their problem solving process. In this paper, we will describe MEAs and how they are being used for misconception identification. Potential MEA topics and a sample MEA are provided and discussed in detail.
