With the continuous development of technology and people's dependence on the Internet, more and more teachers' professional development is carried out on the Internet. Since no one has studied the professional development of online middle school teachers, we did this study based on this research gap. This article is a research on the professional…

Action research is defined as using research activities to develop concrete societal practices. Action research understands the change of practice as being already a central aim of the research process itself, and it also seeks to contribute to the professional development of all participants in the particular field of study. Even though (or maybe…

This study aims to determine and describe the new domain-specific expertise of experienced chemistry teachers in teaching an innovative context-based unit about macro-micro thinking in structure-property relations. The construct of "teachers' domain-specific expertise" was used to analyse the new repertoire chemistry teachers need to acquire to…

This paper reports on the initial outcomes from the end of the fourth year of a 5 year research and professional development project to improve chemistry teaching among three cohorts of chemistry teachers in Manitoba, Canada. The project responds to a new curriculum introduction advocating a tetrahedral orientation (Mahaffy, "Journal of…

Involving teachers in early stages of context-based curriculum innovations requires a professional development programme that actively engages teachers in the design of new context-based units. This study considers the implementation of a teacher professional development framework aiming to investigate processes of professional development. The…

The aim of this study is to develop a framework for professional development programmes that empowers chemistry teachers to teach and design context-based chemistry curricula. Firstly, teachers' involvement, their concerns and their professional development in several context-based curriculum innovations is discussed. Secondly, to develop such a…

This article reports on the initial findings of research carried out with a cohort of science teachers engaged in a professional development course at a northwest England university.

Modern computer-based molecular modelling opens up new possibilities for chemistry teaching at different levels. This article presents a case study seeking insight into Finnish school teachers' use of computer-based molecular modelling in teaching chemistry, into the different working and teaching methods used, and their opinions about necessary…

The purpose of this study was to explore the relationship between teachers' (N = 69) participation in constructivist chemistry professional development (PD) and enhancement of content (CK) and pedagogical content knowledge (PCK) (representational thinking and conceptual change strategies) and self-efficacy (PSTE). Quantitative measures assessed…
