Teachers from three secondary schools together with the authors initiated a project to develop teaching strategies and resources to implement a new Hong Kong Junior Secondary Science Curriculum (JSSC) introduced in 2000. The teachers met regularly to share their experiences of the teaching designs and classroom practice. Through working together, teachers became mentors and learners of the other teachers. Data were collected from records of teacher meetings, lesson observations, teacher interviews and student interviews to evaluate the effectiveness of the project. Findings of this study revealed that teaching approaches of these teachers changed significantly, particularly towards more student-centred modes of learning. Active student participation encouraged the teachers to explore and try out innovative ways of learning and teaching of science. The positive feedbacks from students stimulated the teachers to reflect their role as facilitators and curriculum decision-makers rather than passive transmitters of the curriculum. To be successful in making changes in the teaching culture, findings indicated that the teachers shared the common goal of delivering quality science education. The change had also to be taken place in a context in which high quality teaching resources developed by the teachers had an impact on pupils' learning. The change was not only on the pedagogical content knowledge applied in classes. It was also a change in the belief in science education. However without the characteristics of a competent teacher such as good science background and good presentation skills, such changes would not be able to succeed.

Teaching English as a second language in Hong Kong has been undergoing considerable change in the last two decades, from the Oral-structural Approach to the Communicative Approach, and more recently the Task-based teaching and learning. Hong Kong ESL teachers are having to rethink classroom strategies. This poses a particular problem for student teachers who have limited understanding of what this involves. Moreover, the only experience they can rely on is their own as pupils, and this has been rendered largely irrelevant at a time when the standard of English in schools in Hong Kong is said to have been declining. The speaker explores how eight student teachers who consider themselves linguistically deficient develop their professional knowledge in learning to teach ESL. Results show that the thinking, knowledge and practices of these student teachers who entered teacher education with an 'empty disk' did change critically on the course. Implications are drawn for developing TESL programmes for teaching candidates who are less competent in English.

The contents of nature of science (NOS) in science curriculum have been changed in the past few decades. In the sixties, the contents were mainly about science process skills. Later, the tentative, replicable, probabilistic, humanistic, historic and empirical natures were included in the seventies and psychological and social factors were included in the eighties. In the recent science education reforms of many countries, students' adequate understandings of NOS were explicitly stated or required. In order to achieve similar educational goal in the current curriculum reform in Hong Kong, we must first develop a valid, reliable, practical and easy-to-analyse research instrument for large-scale probing of students' understanding and views of NOS. The present paper reports on how we have made use of 3 cases from history of physical science (to wit, biography of Galileo Galilei, Thomson and Rutherford's atomic models, and observation of "canali" in Mars) plus three other historical cases and issues from the biomedical field (to wit, Jenner's use of vaccination for immunization against smallpox, discovery of SARS virus in Hong Kong, and discovery of the mosquito's role in transmitting the malaria disease) to develop two new sets of questionnaire research tools. The major criticisms on past paper-and-pencil NOS questionnaire instruments had been properly considered and addressed during the design process. Subsequently, questionnaire surveys were administered to about 640 students at junior secondary level in 6 Hong Kong schools and about 450 science students at senior secondary level in another 6 schools in Hong Kong. Those surveyed data were triangulated with the group interviews of a few randomly selected students in each class. Some key findings on the students' attitudes and misconception towards NOS will be presented in this conference paper together with a brief discussion on their implication in science education.
