This paper reports the findings of a quasi-experimental study that investigated the impacts of effective group work on Hong Kong science classrooms. One hundred and fifty-two Secondary 2 (or Grade 8) students from two schools participated in a teaching intervention (comprising 16 lessons) in which they studied the topic 'Making Use of Electricity' and resolved a series of related scientific inquiries. Informed by both the quantitative (i.e. diagnostic tests) and qualitative (i.e. science inquiry questions, audio-recordings of group discussions and focus-group interviews) results of the study, this paper reveals that effective group work can narrow the social and gender differences in Hong Kong students' science performance. Whilst a dynamic and respectful learning environment was found to help economically disadvantaged and female students to overcome such barriers to science learning as low self-esteem and high anxiety, a gender-balanced and socioeconomically diverse arrangement was found to be an important element of social group work practice. Finally, the study's broad implications for teacher and peer support for science teaching worldwide are also discussed. Copyright ©Routledge.

This paper examines the roles of multimodality and thematic patterns in the teaching of the particle model of matter. Although the particle model is a fundamental topic in science education, there is no consensus on (1) whether or not the model should be introduced in early grades and (2) how to introduce the model to students for the very first time. Drawing from teacher development projects in Sweden (Grade 3) and in Hong Kong (Grade 7), we suggest that the learning and teaching of the particle model can be facilitated by utilising a variety of modes. With multimodal scaffolding, Grade 3 students were able to demonstrate aspects of the particle model related to the expansion of gases in a warmer environment. The paper illustrates teaching episodes from the two projects in terms of (i) aspects of the particle model that were constructed using different semiotic modes, (ii) shifts in the salience of different modes in the teaching and learning process, and (iii) a thematic pattern that the classroom interactions adopted to explain puzzling phenomena. For a theoretical advancement, we suggest that thematic analysis should be extended to multimodal interactions. Copyright © Routledge.

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.

In Hong Kong, student interest and achievement in science have been declining in recent years. We thus aim to seek ways to improve our science education. This paper reports an attempt of using the flipped classroom approach together with the Next Generation Science Standards (NGSS) to deliver a science unit ("electrical conductors and insulators"). This exploratory study was divided into two stages. In Stage 1, the teacher-researcher designed the science lessons using the NGSS and prepared flipped learning materials (e.g., pre-class videos, online exercises, class activities). In Stage 2, these lessons were implemented in a Hong Kong secondary school, involving a total of 32 ninth-graders from two classes. At the end of this study, two focus group interviews (five students each) were conducted to understand student perceptions of flipped science learning. Teacher reflections of the implementation were also collected and analyzed to reveal his experiences of flipping with the NGSS. Overall, the findings suggest that the students perceived flipped science learning positively because of the ability of self-paced learning, better class preparation, and more in-class interactions. From the teacher's point of view, however, the science curriculum in Hong Kong and the NGSS are different in terms of their focus and content. Time constraint and inadequate laboratory equipment in school also hindered the implementation of the NGSS in Hong Kong. We recommend further research be conducted to investigate how to adopt the NGSS in other topics of Hong Kong science education and examine its effects on student interest and achievement in the long run.

The paper reports on an empirical study on adopting an innovative pedagogical design in project-based learning to improve upper primary students' problem solving skills in science learning. A Grade 6 class in a Hong Kong primary school was involved in this study. The findings show that the students produced high group artifacts/projects in problem-solving quality and were positive in facing challenges in their project-based learning process. This indicates that project-based learning with PF instructional design can be an effective way to develop students' problem solving skills. Copyright © 2018 authors.

This paper aims to examine teachers’ use of strategies and approaches in integrating Plastic Resources Education (PRE) into primary school life in order to overcome the challenges encountered during implementation to promote environmentally friendly practices. Case studies with eight Hong Kong teachers from PRE-participating primary schools were invited to take part in focus group interviews, to explicate their personal stories and experiences associated with the PRE implementation in primary schools. Based on the data collected from the teachers’ sharing, several challenges which are commonly reported in the previous literature, including lack of time, shortage of manpower, and insufficient pupil engagement were found. The teachers tackled the barriers by using different strategies to improve pupils’ involvement as well as getting support from the relevant stakeholders of school management and parents. The case studies provide crucial and relevant information which can be used as a reference for other schools to integrate PRE more efficiently to facilitate learning. Copyright © 2018 ASPE.

This paper, through discussion of a teaching intervention at two secondary schools in Hong Kong, demonstrates the learning advancement brought about by group work and dissects the facilitating role of teachers in collaborative discussions. One-hundred and fifty-two Secondary Two (Grade 8) students were divided into three pedagogical groups, namely "whole-class teaching", "self-directed group work" and "teacher-supported group work"groups, and engaged in peer-review, team debate, group presentation and reflection tasks related to a junior secondary science topic (i.e. current electricity). Pre- and post-tests were performed to evaluate students' scientific conceptions, alongside collected written responses and audio-recorded discussions. The results indicate that students achieved greater cognitive growth when they engaged in cooperative learning activities, the interactive and multi-sided argumentative nature of which is considered to apply particularly well to science education and Vygotsky's zone of proximal development framework. Group work learning is also found to be most effective when teachers play a role in navigating students during the joint construction of conceptual knowledge.

The subject of Graphic Communications (and the more-focused subject of Technical Drawing currently taught in Hong Kong) is usually taught in schools as either a stand-alone subject or as part of other technology subjects such as Design & Technology. Traditionally, textbooks and their accompanying problems in workbooks contain set exercises that often lack relevance to each other and/or the students. One way to provide more meaning in the teaching/learning of the subject is to utilize a thematic approach. This paper will present a rationale for using a thematic approach for teaching Graphic Communications. Examples of student work and suggestions for introducing thematic topic will be give.

The recently implemented HKCEE Chemistry curriculum has adopted a STS approach which is relatively new to this subject in Hong Kong. It was thus considered appropriate to find out how the teachers adapt to this change in approach. Consequently, a survey in the form of questionnaire was conducted in April, 96 to seek the opinions of teachers on the change. The questionnaire was designed to survey the teachers' opinions on the change in content, the new activities, availability of suitable resources and the format of the examination. Questionnaires were sent to 300 schools, in which 164 schools responded, giving a response rate of 54.6%. 12 of the schools surveyed do not offer Chemistry at HKCEE level. The results revealed that 78% of the teachers claimed that they are aware of the rationale behind the change in the Chemistry curriculum. In addition, about 80% of the teachers agreed that the introduction of society related topics are useful to students intending to study Chemistry beyond HKCEE level. However, over 60% of the teachers surveyed claimed that the new curriculum do not provide enough chemical knowledge for students to pursue further studies in chemistry. In addition , about 60% of the teachers think that the omission of certain topics from the old curriculum is likely to lead to inadequate background knowledge in chemistry. As to the new teaching activities , 48% of the respondents admit that they have never carried out the debates while over 90% of the teachers claimed that they have carried out the decision-making exercises with the students. Furthermore, 54% of the teachers found that the students participate actively in the new activities. As to the non-inclusion of the new activities in the teaching process, 80% of the teachers claimed that they do not have enough time to do so. With regard to the format of the examination, 76% of the interviewees welcome the change in the format of the HKCEE examination. However, over 70% of the teachers found that

This paper describes the outcome of a collaboration project, a science school-based curriculum development proje between the Hong Kong Institute of Education and five primary schools. The project was an attempt to address thre problems perceived by the teachers concerning primary science teaching including, lack of subject knowledge, lacki resources and feeling of insufficiency in facilitating pupils' learning. In addressing these problems, the project tea devised a number of strategies for the teaching of science based on a constructivist view of learning and supported teachers through a school-based curriculum development model. Strategies used include: designing a series of teachir packages to lessen the burden of teaching in terms of time and resources constraints; and organizing school-bas workshops to facilitate professional discussion and reflection on teaching practices. This paper describes the variourj phases of the school-based curriculum development project including the planning, implementation and evaluation of I project. The effectiveness of the project in terms of professional interaction and application of the teaching kit examined by analyzing the interview responses. The findings of the project provide evidence that there were improvements in the learning and teaching of science in primary classrooms. Finally, drawing on the findings, the paper introduces ways of improving the project and future directions of research.
