This paper examines the feasibility of using historical case studies to contextualise the learning of the nature of science and technology in a biology lesson. Through exploring the historical development of vaccine technology, students were expected to understand the complexity of the relationships between technology and science beyond the…

Self-generated analogical models have emerged recently as alternatives to teacher-supplied analogies and seem to have good potential to promote deep learning and scientific thinking. However, studies of the ways and contexts in which students generate these models are still too limited to allow a fuller appraisal of these models' effectiveness in…

Education for scientific literacy entails the development of scientific knowledge and the ability to apply this knowledge and value judgments to decisions about real-life issues. This paper reports an attempt to involve secondary level biology students in making decisions about an authentic socio-scientific issue--that of bat conservation--through…

A paper was published in JBE in 2001 which examined the background of the education reform launched in 2000 in Hong Kong, and reviewed existing practices as well as beliefs in science and biology assessment among secondary teachers in Hong Kong. The direction of the reform was to take the emphasis away from public examinations as the sole…

The Teacher Assessment Scheme (TAS) is a form of school-based assessment that has recently replaced the external practical examination in AL Biology of Hong Kong. This study aimed at understanding the problems encountered by teachers in implementing this innovation. Over 300 teachers expressed their concern about different aspects of the TAS in a…

Describes the background of the proposed reform, and reviews existing practices in science and biology assessment among teachers in Hong Kong. Analyzes current beliefs about science teaching and learning. Discusses the change in beliefs required in order to implement the proposed reform. (Author/MM)

Science teachers ask questions to assess students' cognitive abilities and to promote student motivation in learning. Cognitive questions are usually divided into low-order and high-order types. According to the conceptual change model of learning, teachers can also use questions to facilitate the construction of knowledge by students. These…
