作为形成性评估的教学工具,经过研究验证的点击问题相对容易实施,当按顺序开发和实施时,可以提供有效的支架。我们介绍了一个研究验证的点击问题序列(CQS)的实施结果,该序列旨在帮助学生理解两态量子系统的时间发展。这项研究是在一门高级本科生量子力学课程中进行的,连续两年在虚拟课堂和面对面课堂上进行。本文讨论的CQS在两种教学模式中的有效性是通过评估学生在传统授课教学后的表现并将其与参与CQS后的表现进行比较来确定的。
Research-validated clicker questions as instructional tools for formative assessment are relatively easy to implement and can provide effective scaffolding when developed and implemented in a sequence. We present findings from the implementation of a research-validated clicker question sequence (CQS) on student understanding of the time-development of two-state quantum systems. This study was conducted in an advanced undergraduate quantum mechanics course for two consecutive years in virtual and in-person classes. The effectiveness of the CQS discussed here in both modes of instruction was determined by evaluating students' performance after traditional lecture-based instruction and comparing it to their performance after engaging with the CQS.
