Refinement of Introductory Engineering Thermodynamics Computer-Based-Learning Modules

在这个项目中，我们正在完善、扩展和严格评估一个现有的交互式、多媒体、自定进度的基于计算机的入门工程热力学学习原型。原型包括典型工程热力学入门课程中的所有主题，并结合了几种主动学习技术，如实验室模拟、接触热力学设备、概念动画、即时反馈、正强化等。为了提高教师对学生学习的理解，我们在原型中增加了电子数据采集。这些数据衡量使用模式（例如，完成任务的时间、学习时间的分布和屏幕访问的频率）和用户表现（例如，内部小型考试、课堂考试和教师对学生的评价）。还评估了学生的看法（例如，问卷调查和学生访谈）。对这些结果进行分析，以完善和改进现有的原型，并确定在基于计算机的教学（CBI）模式下最有效的主动学习技术。

Engineering - Other (59) In this project, we are refining, expanding, and rigorously assessing an existing interactive, multi-media, self-paced computer-based learning prototype for introductory engineering thermodynamics. The prototype includes all topics in a typical introductory engineering thermodynamics course and incorporates several active learning techniques such as laboratory simulations, exposure to thermodynamic equipment, animation of concepts, instantaneous feedback, positive reinforcement, and others. In order to improve the instructors' understanding of student learning, we are adding electronic data gathering to the prototype. These data measure usage patterns (e.g., time on task, distribution of study time, and frequency of screen visits) and user performance (e.g., grades on internal mini-examinations, in-class examinations, and instructor evaluation of students). Student perceptions (e.g., questionnaires and student interviews) are also being assessed. These results are analyzed to refine and improve the existing prototype, and to identify those active learning techniques that work best in the computer-based-instruction (CBI) mode.
