自90年代中期以来，工程设计一直是工程认证课程的要求。这种对工程设计的重视已经在新生和大四的工程课程中引入了显着的变化，许多工程课程提供顶点（高级）和/或基石（新生）设计课程。然而，设计相关的内容和经验，在第二年和第三年的工程课程仍然不太常见，由于在中间几年的基础工程科学课程的重点。本研究探讨了在这些课程之一，开发设计能力（思维，过程和技能）的可能性。所使用的方法是将真实的世界，开放式的问题解决，特别是真实的工程问题为中心的学习（AEPCL），到一个初级的传热课程。AEPCL以真实工程问题（AEPs）为背景，通过解决开放式、结构不良的问题来培养学生的设计能力。结果表明，经历过AEPCL的学生比没有经历过AEPCL的学生表现出更好的设计能力。通过AEPCL，学生学习如何收集更好的信息，做出更合理的假设，参与更好的流程，并在工程设计中获得更合理，无错误和高质量的解决方案。
Engineering design has been a requirement in the curriculum for engineering accreditation since the mid-90 s. This emphasis on engineering design has introduced significant changes to engineering curricula in freshmen and senior years with many engineering programs offering capstone (senior) and/or cornerstone (freshmen) design courses. Yet design-related content and experiences in the second and third years of the engineering curricula remain less common due to the heavy emphasis on fundamental engineering science courses in the middle years. This study investigated the possibility of developing design ability (thinking, process, and skills) in one of these courses. The method used was to incorporate real world, open-ended problem solving, specifically authentic engineering problem centered learning (AEPCL), into a junior-level heat transfer course. AEPCL uses authentic engineering problems (AEPs) as the backdrop to develop students' design abilities through solving open-ended, ill-structured problems. Results indicate that students who experienced AEPCL showed better design abilities than comparable students who did not experience AEPCL. Through AEPCL, students learn how to collect better information, make more reasonable assumptions, engage in better processes, and arrive at a more plausible, error-free, and high-quality solution in engineering design.
