TL;DR: In this article, the authors constructed a valid and reliable multiple-choice conceptual survey to investigate students' understanding of introductory quantum physics concepts, which was administered to 312 students at the University of Sydney.

TL;DR: The Interactive Lecture Demonstration (ILD) is designed for large lecture classes and, if measured using specific conceptual surveys, is purported to provide learning gains of up to 80% as discussed by the authors.

TL;DR: The Mechanical Wave Conceptual Survey (MWCS) as discussed by the authors was developed to diagnose the students' conceptions of the basic concepts of mechanical wave concepts using the open-ended Wave Diagnostic Test (WDT).

TL;DR: Tongchai et al. as mentioned in this paper developed a multiple-choice conceptual survey in mechanical waves and found that students were committed to these conceptual models, as evidenced by the consistency with which they answered the questions.

TL;DR: In this article, the authors describe the design of the specialized guided worksheets for the topic of electric field, and its evaluation, and their results indicate that the specialized guides made a difference in topics that students find challenging, but there were issues around certain topics which students found challenging.
