Engineering-Mechanical (56) The project is adapting and implementing selected design-build-test (DBT) activities in fluid-thermal systems, heating ventilation and air-conditioning from projects developed at the University of Wisconsin-Milwaukee, Colorado State University and the University of Idaho. Thermal science curriculum are being reformed with changes to three required lecture and laboratory courses in such a way that the contents of a stand-alone mechanical engineering laboratory course is integrated with lectures through the execution of design, build, and test (DBT) activities. Two DBT course modules are being developed, one in heat exchangers and the other in scaled building air-conditioning systems.Structure and methods being employed include the following. (1) A hands-on experience is being used to provide students with a better understanding of the abstract concepts discussed in lectures by establishing a clear linkage to industrial applications through Design Build and Test (DBT) projects. (2) The adaptation is enhancing students' learning by providing them with open-ended design problem experiences in the mid-stage of their engineering degree program. (3) Improved comprehension of the thermal-fluid contents is being achieved through practical application and immediate, relevant implementation. (4) DBT activities are enhancing students' critical thinking skills by requiring the students to make decisions that directly affect the outcomes of the process. (5) The process is fostering a cooperative learning environment and is providing a strong sense of accomplishments for the students.The evaluation process is assessing (1) how well the DBT approach equips students to apply mathematics, science, and engineering to thermal-fluid systems design, (2) students' ability to function within teams to develop, professional and ethical responsibility, and (3) how well the reformed curriculum contributes to an increase in student's interests in thermal/fluid subjects, retention, and recruitment of prospective students, and in particular, underrepresented classes of students.

工程-机械(56)该项目正在调整和实施从威斯康星大学密尔沃基分校、科罗拉多州立大学和爱达荷州大学开发的项目中选定的流体热系统、供暖通风和空调方面的设计-建造-测试(DBT)活动。正在对热学课程进行改革，将三门必修课和实验课改为一门独立的机械工程实验课，通过实施设计、建造和测试(DBT)活动将其内容与讲座相结合。两个DBT课程模块正在开发中，一个在换热器中，另一个在大规模建筑空调系统中。(1)通过设计、构建和测试(DBT)项目与工业应用建立明确的联系，使用实践经验使学生更好地理解课堂上讨论的抽象概念。(2)适应是通过在工程学位课程的中期阶段为学生提供开放式设计问题体验来促进学生的学习。(3)通过实际应用和即时相关实施，提高了对热-流体内容的理解。(4)DBT活动通过要求学生做出直接影响过程结果的决定来提高学生的批判性思维能力。(5)这一过程正在培养一种合作学习环境，并为学生提供强烈的成就感。评估过程是评估(1)DBT方法在热-流体系统设计中应用数学、科学和工程学的能力如何，(2)学生在团队中发挥作用以发展专业和道德责任的能力，以及(3)改革后的课程在多大程度上有助于提高学生对热/流体学科的兴趣，留住和招收未来的学生，特别是代表不足的学生。
