Using a clicker question sequence to teach time-development in quantum mechanics

Abstract

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. The effectiveness of the CQS was determined by evaluating students' performance after traditional lecture-based instruction and comparing it to their performance after engaging with the CQS.
