CCLI: Hands-on Module Development for Student Mastery of Electric Circuit Concepts

工程-电气（55）该项目正在开发和评估实际操作模块，用于以讲座为基础的入门电路课程。这些模块是基于基于问题的学习框架，它们是在STAR-Legacy周期之后建模的。他们首先向学生提出挑战，然后要求他们收集信息，选择、实施和评估解决方案。为了确定成功与否，一种传统的治疗控制组方法被用来衡量学习方面的进步。除了对照组之外，还有两个治疗组：一个是学生通过模拟接触模块，另一个是学生以动手的方式接触模块。掌握程度将通过评估工具来衡量，评估工具侧重于对直流和交流电路概念的概念性理解。这些工具将有助于确定这些实践模块在提高学生成绩方面所起的作用，并将用于推动未来适当材料的开发。将评估调查与人口统计数据相结合，可以让调查人员检查不同人群在学习方面的进步是如何变化的。他们计划通过会议和期刊出版物传播他们的模块，并在其他工程项目中推广使用，特别是在德克萨斯州。关于更广泛的影响，该项目通过促进教学方法来解决多样性问题，研究表明，这些方法在保留代表性不足的族裔群体和工程领域的妇女方面是有效的。

Engineering - Electrical (55)The project is developing and evaluating hands-on modules for use in lecture-based, introductory electric circuits courses. The modules are based upon the problem-based learning framework and they are modeled after the STAR-Legacy cycle. They start with a challenge to the students and then require them to gather information and to choose, implement, and evaluate a solution. To determine success, a traditional treatment-control group methodology is being used to measure improvements in learning. In addition to the control group, there are two treatment groups: one where the students are exposed to the modules via simulation and one where the students are exposed to the modules in a hands-on manner. Mastery will be measured via assessment instruments that focus on conceptual understanding of DC and AC circuit concepts. These instruments will help to identify what role these hands-on modules played in improving student achievement and will be used to drive future development of appropriate materials. Coupling the assessment surveys with demographic data is allowing the investigators to examine how improvements in learning vary among diverse populations. They plan to disseminate their modules through conference and journal publications and to promote their use in other engineering programs, particularly with those in Texas. Regarding broader impacts, the project addresses diversity by promoting pedagogies which research has shown to be effective in the retention of underrepresented ethnic groups and women in engineering.
