Interviews with key scientists involved in research on severe acute respiratory syndrome (SARS), together with analysis of media reports and documentaries produced during and after the SARS epidemic, revealed many interesting aspects of nature of science (NOS) and authentic scientific inquiry. This novel insight into practice in the rapidly growing field of molecular biology was used in the development of instructional materials for use in the pre-service and in-service teacher education programme at The University of Hong Kong. The elements of NOS and scientific inquiry identified in the scientific research on SARS were explicitly emphasized in our instructional materials. The contemporary real-life context of SARS was found to be effective in promoting student-teachers' understanding of NOS and scientific inquiry, particularly in terms of: the realization of inseparable links between science and the social, cultural, and political environment; deeper understanding of how science and technology impact on each other; and a richer appreciation of the processes of authentic scientific inquiry and the humanistic character of scientists. The effectiveness is attributed to immediacy, relevance, and familiarity, making the abstract tangible, personal experience of science history, and the powerful affective impact of the interviews with scientists.

This paper reports findings about a curriculum innovation conducted at The University of Hong Kong. A CD‐ROM consisting of videos of two lessons by different teachers demonstrating exemplary science teaching was used to elicit conceptions of good science teaching of student‐teachers enrolled for the 1‐year Postgraduate Diploma in Education at several stages during the programme. It was found that the videos elicited student‐teachers' conceptions and had impact on those conceptions prior to the commencement of formal instruction. It has extended student‐teachers' awareness of alternative teaching methods and approaches not experienced in their own schooling, broadened their awareness of different classroom situations, provided proof of existence of good practices, and prompted them to reflect on their current preconceptions of good science teaching. In several ways, the videos acted as a catalyst in socializing the transition of student‐teachers from the role of student to the role of teacher.

Procedural and conceptual knowledge for solving a basic quantitative problem in chemistry by expert and novice secondary school students is reported. Experts use a known qualitative procedure with a working forwards strategy to obtain a numerical solution. Novices attempt a means-ends analysis strategy which is often unsuccessful, so switch to a simple formula-driven working forwards strategy to obtain a numerical solution, the qualitative procedure being either omitted or only partially formed. A gradual shift in strategies and representations used as expertise increases was observed. Differences with findings for problem solving in physics were also found. Experts' conceptual knowledge is accurate and linked to underlying procedural knowledge, whereas novices have misconceptions and a poor understanding of formulae. Conceptual understanding, use of a qualitative procedure, and the type of strategy used, are major differences between experts and novices. Instructional techniques are suggested in these areas to enhance problem solving and teaching.

This paper argues for the need to advocate a method of empirical science as the neutral language for making intellectual judgments concerning the modern technological world and moral and value issues. The author contends that scientific method, and only scientific method, could sustain knowledge systems that are logical, coherent, and cumulative in its results.

This paper presents an overview of science education provisions in Hong Kong. Using document analysis and some data from the Second International Science Study, the quality of science curriculum is contrasted from an international context.
