Changing primary teacher trainees' attitudes to science

A study of primary teacher trainees' perceptions and attitudes to science in 1990, has been useful in designing a semester unit aimed at increasing the confidence and interest of first year students at Victoria College. This paper outlines the background survey and discusses some, of the results and how they were used to develop the Professional Readiness Study-Understanding Science. This unit attempts to change attitudes by focussing on metacognition and encourages students to understand and control their own learning. Discussion involves teaching and learning strategies and alternative assessment approaches including the student's journal-the Personal Record. Specializations: technology for learning, health education. Specializations student understanding of biology, particularly genetics, evaluation. Specializations: children's learning in science, language in science.     

Primary pre-service teachers' pedagogical reasoning skills

This paper discusses a preliminary investigation into primary pre-service teachers' pedagogical reasoning skills. Results from this investigation led to the development of a problem-based learning model which focused on improving primary pre-service teachers' pedagogical reasoning skills. The problem-based learning model uses pedagogical reasoning as the basis for creating problem situations for the pre-service teachers to investigate. The paper reports on pre-service teachers' views on the use of the approach to improve their pedagogical reasoning skills. Specializations: science teacher education, learning in science, chemistry education. Specializations: student learning, conceptual change, technology education, curriculum evaluation.

Will Undergraduate Students Play Games to Learn How to Conduct Library Research?

This exploratory study examines whether undergraduate students will play games to learn how to conduct library research. Results indicate that students will play games that are an integral component of the course curriculum and enable them to accomplish overall course goals at the same time they learn about library research.     

Student teachers' entry perceptions about teaching primary science: Does a first degree make a difference?

It is problematic whether primary teachers benefit by completing a first degree especially when the teaching of specific subjects, here science, is the focus of attention. This study reports the comparative results of interviewing thirteen Canadian and ten Australian student teachers, both about to commence their Bachelor of Education. The Canadian students had completed an initial degree while nine of the Australian students were school leavers. The interviews, which explored views about teaching primary science, were analysed with this factor in mind. Student teacher perceptions reported include: how to recognise a “good” primary science teacher; perceptions of self as a “good” primary science teacher; expectations of how the teacher education program could assist their science teaching; and whether (for the Canadian students) the initial degree will help in becoming a primary science teacher. Analysis of the interviews suggests possible influences a first degree (among other factors) may have on perceptions related to primary science teaching and raises questions about what is the best general approach for preparing primary teachers to teach science effectivly.     

Introduction: Political Communication in Asia

This study analyses the structure of programmes of the Bangladesh Television (BTV) broadcast over a period of 23 years (1966–89). It presents an analysis of programmes of ten different time‐points, and determines the changes over this time period. The ratio of imported and domestic programmes in Bangladesh Television is also studied. One of the findings of this study is that television in Bangladesh is used predominantly as a medium of entertainment since its inception in 1964 and is still being treated as such. Despite phenomenal development in the technical facilities, its structure of programmes remains almost the same. This study also reveals that Bangladesh Television is still dependent upon imported programmes to a large extent to feed its transmission hour.
