This paper reports on an interview study of 18 Grade 10-12 students' model-based reasoning of a chemical reaction: the reaction of magnesium and oxygen at the submicro level. It has been proposed that chemical reactions can be conceptualised using two models: (i) the "particle model," in which a reaction is regarded as the simple…

This paper proposes a model-based notion of "submicro representations of chemical reactions". Based on three structural models of matter (the simple particle model, the atomic model and the free electron model of metals), we suggest there are two major models of reaction in school chemistry curricula: (a) reactions that are simple…

This study investigated students' interpretation of diagrams representing the human circulatory system. We conducted an interview study with three students aged 14-15 (Year 10) who were studying biology in a Hong Kong school. During the interviews, students were asked to interpret diagrams and relationships between diagrams that represented…

The study aimed to explore Chinese language teachers' perception and implementation of instruction based on self-regulated learning (SRL) in a researcher-teacher collaborative project. The participants were 31 teachers and their 10th grade students, from six secondary schools in Hong Kong. The findings of questionnaires, interviews, and…

This study focuses on how two teachers working in reduced-size secondary classes of the same grade adapted their pedagogy as a result of a brokered dialogue between myself as researcher and 43 grade 10 students from the teachers' classes. Research was carried out over the course of one academic year. First, students' perspectives on studying in a…

This small-scale study aimed to explore how the reporting and feedback system in an inviting school in Hong Kong attempts to facilitate students' learning and development. In particular, the study examined how students in an inviting setting felt about the reporting system in relation to their own learning and development. Any associations between…

This paper presents a model of collaborative and reflective professional development for teachers that focuses on student learning. The model comprises a cyclical series of lessons that were carried out in Hong Kong with 94 Secondary Four (Grade 10) students. The lessons were designed to develop the reading skill of inferring characters' traits…
