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。这些模块基于以问题为基础的学习框架，并仿照明星-遗产循环。他们从向学生提出挑战开始，然后要求他们收集信息，并选择、实施和评估解决方案。为了确定成功与否，正在使用一种传统的治疗对照组方法来衡量学习方面的改善。除了控制组，还有两个处理组：一个是通过模拟让学生接触到模块，另一个是让学生通过动手的方式接触到模块。掌握程度将通过评估工具进行衡量，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动手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结合起来，使研究人员能够检查不同人群在学习方面的改善情况是如何变化的。他们计划通过会议和期刊出版物传播他们的模块，并促进它们在其他工程项目中的使用，特别是在德克萨斯州的项目中。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，这种教学方法在保留未被充分代表的族裔群体和从事工程工作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.
