The Primary General Studies Syllabus consists of four major content areas, namely Healthy Living, Living Environment, Natural World and Science & Technology. When these content areas are examined, discrete and rather independent elements are found in the topics of Science, Health Education and Social Studies, although a high degree of flexibility exists with respect to integration of these elements in teaching different themes of General Studies. The area of Living Environment is heavily social oriented whereas the areas of Natural World and Science & Technology are heavily science oriented. Furthermore, within the area Healthy Living, there is a high proportion of biology and health-related content knowledge associated with the topics covered. Given the significance of science and health components in the General Studies syllabus, a study has been initiated by our group of HKIEd Science Department staff to investigate the teaching competency of primary teacher trainees in science and health education components of General Studies. The study is a continuous one and is divided into several stages. In the initial stage of the project, a teaching competency self-evaluation questionnaire was designed and administered to representative groups of full-time and part-time HKIED teacher trainees to seek their self-evaluation feedback on their competency to teach science and health components of the General studies curriculum (Lui, Chan & Tsang, 1996). The competency questionnaire was composed of 3 major parts: a) Knowledge, b) Pedagogy, and c) degree of mastering specific General Studies science and health education topics (knowledge/ pedagogy). The teacher trainees felt that they needed to be better equipped with science and health knowledge for the teaching of science and health aspects of the General Studies curriculum. Furthermore, they felt there was not enough treatment of pedagogy as well as pedagogical content knowledge in science and health related components in HKIEd
