本文总结了我们使用目前正在开发的热与运输概念清单（TTCI）对美国四所工程学院收集的beta测试结果的分析。该仪器包括传热、流体力学和热力学方面的问题，旨在引出工程学本科生在这些学科中误解的本质。除了使用传统方法通过相关系数确定TTCI可靠性外，我们还对六个传热问题应用了交叉表数据分析，以确定学生的误解。这些分析的结果确定了在传热问题和背景中持续存在的两类误解：1)对能量和温度差异的混淆，以及2)对稳态和平衡过程差异的混淆。
This paper summarizes our analysis of beta test results collected at four U.S. engineering schools using the Thermal and Transport Concept Inventory (TTCI) currently under development. The instrument consists of questions in heat transfer, fluid mechanics, and thermodynamics and is designed to elicit information about the nature of undergraduate engineering students’ misconceptions in these disciplines. In addition to using conventional methods for determining TTCI reliability with correlation coefficients, we have applied cross-tabulation data analysis for six heat transfer questions to identify robust student misconceptions. The results of these analyses identified two categories of misconceptions which persist across heat transfer problems and contexts: 1) confusion about differences between energy and temperature, and 2) confusion about differences in steady-state and equilibrium processes.
