Teaching Science Through Home and Second Languages as the Medium of Instruction: a Comparative Analysis of Junior Secondary Science Classrooms in Hong Kong

Positioned in the Hong Kong education context, this article evaluates the effects of teaching science through home and second languages (i.e. Chinese and English) in Secondary 2 (or eighth grade) science classrooms. A total of 479 students, divided into two language instruction groups, participated in a teaching intervention comprising 16 lessons on the topic of ‘Making Use of Electricity’. Informed by the results of a mixed-methods study with a quasi-experimental design, with data collected from science diagnostic tests, inquiry questions and focus group interviews, this article reports that Chinese is the most advantageous language of instruction for low- and middle-ability science students, whereas English is more favourable for their high-achieving peers. Whilst Hong Kong students who learnt the focal topic in English were able to rid themselves of certain naive ideas generated from the translation of science terms into Chinese (e.g. pencil ‘鉛筆’ is translated as ‘lead pen’ in Chinese), they were also found to have misconceptions about certain scientific concepts. For example, they were confused about ‘open’ and ‘closed’ circuits because they mixed up the words ‘open’ (‘開放’) and ‘switch on’ (‘開啟’) in English. The study’s broad implications for language support and a mixed-code approach in science teaching worldwide are discussed.

The teaching of literature in a Singapore secondary school: disciplinarity,curriculum coverage and the opportunity costs involved

Set against the backdrop of reinvigorating the study of literature and concerns about the adequate preparation of students for the world of work, this paper explores how a Singapore teacher presented a literary text in the classroom. Drawing on data from a large-scale representative sample of Singapore schools in instruction and assessment practices, we discuss some of the potential consequences of instructional choice-making from a disciplinary perspective. Our findings suggest, for example, that when teacher-dominated discourse and interpretations dominate, instructional flexibility and responsiveness are correspondingly limited and restricted. These courses of action, we contend, may occur contrary to teachers’ plans and expectations. The paper closes by making a call for further longitudinal research across multiple research sites into the nature of literature pedagogy that has a strong disciplinary focus.     

Faculty ratings as a measure of departmental and administrator quality

This study examined the usefulness of faculty ratings as a measure of departmental quality. Two hundred and thirty-three faculty members from six departments responded to two questionnaires relating to the department—the Department Evaluation Survey (DES)—and to the department head—the Administrator Evaluation Survey (AES). A factor analysis of the DES revealed three underlying dimensions: Satisfaction with the Department's Academic Environment, Satisfaction with the Department's Governance and Operating Procedures, and Satisfaction with Student Quality. The factor analysis of the AES identified only one underlying dimension. Both the DES and AES were found to be highly reliable and effective in discriminating among departments. Very high positive correlations were also found between selacted DES and AES items suggesting that the performance of the head plays a very important role in faculty perceptions of the departments, and vice versa. Faculty ratings would appear to be a useful initial criterion in evaluating a department or head.
