Engineering - Mechanical (56)This is Phase 1 CCLI Exploratory project is developing thermal and fluid dynamics modular laboratory exercises based on everyday technology such as bicycle pumps and hair dryers. Experiments on these items are resulting in more relevant learning experiences as students are being confronted with their misconceptions about how and why these objects work. The project is also guiding students to develop correct models for the behavior of the system under investigation. Students are using low-cost, USB-based data acquisition equipment to make exploratory measurements to develop preliminary, empirical models of system performance. Students are then attending regular lectures and returning to the lab to perform additional measurements and exercises. The project is evaluating students' increase in factual knowledge, their ability to recognize misconceptions, and their change in attitudes toward laboratory work. Evaluations of learning outcomes are being published in conference papers and relevant journals. All teaching materials, detailed design of laboratory hardware, student worksheets, homework assignments and exams are being made freely available via the web. The simplicity and low cost of the laboratory hardware are making these products feasible for wide spread adoption.

工程-机械（56）这是第一阶段CCLI探索性项目正在开发热和流体动力学模块化实验室练习的基础上，日常技术，如自行车泵和吹风机。对这些物品的实验产生了更多相关的学习经验，因为学生们正面临着他们对这些物品如何以及为什么工作的误解。该项目还指导学生为所研究的系统的行为建立正确的模型。学生们正在使用低成本，基于USB的数据采集设备进行探索性测量，以开发系统性能的初步经验模型。然后，学生参加定期讲座，并返回实验室进行额外的测量和练习。该项目评估学生在事实知识方面的增长，他们识别错误概念的能力，以及他们对实验室工作态度的变化。对学习成果的评价正在会议文件和相关期刊上发表。所有教学材料、实验室硬件的详细设计、学生作业、家庭作业和考试都可以通过网络免费获得。实验室硬件的简单性和低成本使这些产品能够广泛采用。
