Development and Use of a Conceptual Survey in Introductory Quantum Physics

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 construct a valid and reliable multiple‐choice conceptual survey to investigate students’ understanding of introductory quantum physics concepts. We examined course syllabi to establish content coverage, consulted with experts to extract fundamental content areas, and trialled 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. Using the data from this sample, we performed five statistical tests (item difficulty index, item discrimination index, item point biserial coefficient, KR‐21 reliability test, and Ferguson’s delta) to evaluate the test’s reliability and discriminatory power. The result indicates that our 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‐interpretative. The division of conceptual questions into interpretive and non‐interpretive needs further exploration.     

Reviews and Update

Jonathan Long suggests that current interpretations of values education are dominated by a number of ideas that appear to make attempts to achieve clarity and consensus extremely difficult. He argues that ‘essential to the successful development and promotion of values in a secular state educational system is a shifting of emphasis which enables us to see the context as an opportunity rather than a problem’. He goes on to suggest that schools should focus on what he describes as the ‘roots’ of values. In his view, these roots involve the questions ‘What is it to be human?’ and ‘What counts as human flourishing?’. Thus, schools must engage with issues of identity and direction.     

As we may think: Information literacy as a discipline for the information age

The aim of this paper is to propose information literacy as a soft applied discipline, of key importance in the information society. This is contrasted with the characterization of information literacy as a personal attribute in the U.S. and Australian Information Literacy standards. Vannevar Bush's vision of the technologically connected and enabled scientist is used to introduce a discussion of citizen's information needs and responsibilities in an age of “cheap complex devices.” The authors emphasize the key role of information literacy in this information society. Information literacy is identified as a soft applied discipline, with reference to disciplinary indicators that have been identified in the literature. Building on this concept of an information literacy discipline, the authors propose a mission for information literacy education focused around three elements: information literacy for citizenship, information literacy for economic growth, and information literacy for employability. The paper concludes by identifying that in terms of preparing citizens for managing and taking action in society, information literacy has much to contribute, and that it is vital to nurture this emergent discipline.
