ABSTRACT

        Conceptual surveys have become increasingly popular at many levels to probe various aspects of science education research such as measuring student understanding of basic concepts and assessing the effectiveness of pedagogical material. The aim of this study was to develop a valid and reliable multiple-choice conceptual survey to investigate students’ understanding of introductory quantum physics concepts. The development of the conceptual survey started with examining course syllabuses to establish content coverage, consulting with experts to extract fundamental content areas, and trialling open-ended questions to determine how the selected content areas align with students’ difficulties. The questions were generated and trialled with different groups of students. Each version of the survey was critiqued by a group of discipline and teaching experts to establish its validity. The survey was administered to 312 students at the University of Sydney and 812 students at Mahidol University. Using the data from these samples, five statistical tests (item difficulty index, item discrimination index, item point biserial coefficient, KR-21 reliability test, and Ferguson’s delta) were performed to evaluate the test’s reliability and discriminatory power. The result indicated that this survey is a reliable test. This study also provided data from which preliminary findings were drawn on students’ understandings of introductory quantum physics concepts. The main point is that questions which require an understanding of the standard interpretations of quantum physics are more challenging for students than those grouped as non-interpretive. The division of conceptual questions into interpretive and non-interpretive needs further exploration.
