Articulating the complexity of teachers' professional knowledge development is complicated but highly desirable. Exploration of dilemmas, which interrupt teaching practice, offers the opportunity to view teachers' professional knowledge in action as interruptions signal the limits of knowledge. Transitioning from science teacher to science teacher…

During the last two decades teachers in many countries have found themselves facing new demands and changes. In his "intensification thesis" Apple made a powerful attempt to conceptualize and explain these changes: the growing economic and management oriented perspective on education leads to intensification of teachers' work, implying deskilling…

This paper reports on an interview study conducted with 80 science teachers in 12 secondary schools across Australia. The study was one component of the Science Education Professional Development Project, charged with developing a national strategy for enhancing the professional development of science teachers. Initial interviews were conducted…

Much of the debate about that which comprises teachers' professional knowledge has been important in the academic literature but does not necessarily reflect the reality of how they think as they construct the knowledge that underpins their practice. Typically, teachers are not encouraged to spend time talking about teaching in ways that are…

Research has identified the value of learners using technology to construct their own representations of science concepts. In this study, we investigate how learners, such as preservice elementary teachers, design and make a narrated animation to represent their science knowledge. The type of animation exemplified is called a "Slowmation"…

This paper reports on a study which was designed to examine how CoRes (Content Representations) and PaP-eRs (Pedagogical and Professional-experience Repertoires) might impact the practice of science teachers by considering how they might value (or not) pedagogical content knowledge (PCK) as part of their professional knowledge. The paper is based…

There is growing interest in the professional development of teacher educators as the demands, expectations, and requirements of teacher education increasingly come under scrutiny. The manner in which teacher educators learn to traverse their world of work in the development of their knowledge, skills, and ability is important. This article…

In this article the author states from the outset that he considers scholarship to be pivotal in enhancing the quality of teaching and learning. However, what scholarship is could well be contested, so he offers his understanding of scholarship, how it might be developed, and why he thinks it is so crucial to quality practice. In so doing, he…

The specialist knowledge and skills of science teachers is far too easily overlooked and undervalued, due, in part, to the tacit nature of the knowledge that underpins expert science teachers' practice. For science teachers to better recognize, describe, and share their professional knowledge there is a need to develop new and meaningful ways…

Examines ways in which knowledge might be captured, articulated, and portrayed to others. Develops an approach to articulation and portrayal based on what is called the CoRe (Content Representation), which represents the particular content/topic of the science teaching, and PaP-eRs (Pedagogical and Professional experience Repertoire), which…

In coming to better value teachers' knowledge and practice, there is a need to be able to articulate and document what teachers know and are able to do. This is central in coming to understand pedagogical content knowledge (PCK). This paper presents a working understanding of PCK as it has emerged through a research project and describes the…

This paper describes the rationale for and progress in a substantial research project that aims to develop an understanding of science teachers' pedagogical content knowledge. The background to and purposes for the project are explained. Related projects that study pedagogical content knowledge (PCK) are also described. Approaches to identifying…

The background to this paper is based on the ongoing need to place more attention on the importance of teaching. The aim in so doing is to lead to a better valuing of teaching which, in the case of this paper, is through an exploration of the notion of teaching as a discipline. There are differing views about that which constitutes a discipline…

Explores the problems that a national strategy for the professional development of science teachers attempted to address, and reports on the theme of "loose connections" that emerged. Highlights the weak sense of professional community found among science teachers and their isolation from potentially beneficial influences on their work.…
