任何有意义的举措，以改善教学和学习的介绍控制系统课程需要一个明确的测试学生的概念理解，以确定所提出的方法和活动的有效性。作者提出了一个控制系统概念清单。清单的编制是协作和反复进行的。在学生学习活动之前（前）和之后（后）对学生进行诊断测试。测试的反应进行了分析，以提供教师对他们的教学反馈。运用经典测验理论和项目反应理论，分别对汇总结果进行内部一致性和测量误差分析。学生表现出从测试前到测试后分数的提高，在对所学新概念的理解方面显示出23%-34%的增益。检验的内部一致性在0.61 ~ 0.68之间。结果表明，在33%-66%的分数范围内，测试的精确度最高，这是大多数后测分数出现的地方。
Any meaningful initiative to improve the teaching and learning in introductory control systems courses needs a clear test of student conceptual understanding to determine the effectiveness of proposed methods and activities. The authors propose a control systems concept inventory. Development of the inventory was collaborative and iterative. The diagnostic test was administered to students before (pre) and after (post) student learning activities. Test responses were analyzed to provide instructors with feedback on their teaching. Using classical test theory and item response theory, aggregated results were analyzed to assess internal consistency and measurement error, respectively. Students demonstrated an improvement from pre- to post-test scores, showing gains of 23%-34% in understanding of new concepts learned. The internal consistency of the test has ranged from 0.61 to 0.68. It can be shown that the precision of the test is highest in the score range of 33%-66%, which is where most post-test scores occurred.
