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践模块，用于以讲座为基础的电路入门课程。这些模块是基于问题为基础的学习框架，他们是模仿后的明星遗产周期。 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，传统的治疗对照组方法被用来衡量学习的改善。除了对照组外，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方式接触模块。掌握将通过评估工具，侧重于直流和交流电路概念的概念理解来衡量。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发挥了什么作用，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，使研究人员能够研究不同人群之间学习改善的差异。他们计划通过会议和期刊出版物传播他们的模块，并促进他们在其他工程项目中的使用，特别是在德克萨斯州。 关于更广泛的影响，该项目通过促进工程学来解决多样性问题，研究表明，工程学在留住代表性不足的族裔群体和妇女方面是有效的。

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.
