This study focuses on how teachers learn to teach a new topic and the role played by their developing content knowledge as they teach. The paper is based on seven high school science teachers' studies on the teaching of semiconductors, at the time a new topic in the curriculum. Analysis of artefacts such as teacher concept maps, video recordings of...

Curriculum statements are crucial documents for guiding teaching and learning as they describe the content and skills to be acquired by learners. Textbooks translate curriculum statements into materials for use in schools. This study examines the educative nature of three physical sciences textbooks about electrostatics using the lens of pedagogica...

Extended Curriculum Programmes (ECPs) have been in existence in Africa and Southern Africa since the late 1970s. Various needs for programmes exist, but the primary motivator in the current South African context is a transformative one. While many historically white institutions have either scaled down or closed their ECPs, the University of Pretor...

Article
Stoichiometry, which deals with the quantitative aspects of Chemistry, is a topic students find challenging and which teachers struggle to teach. South African students’ performance in stoichiometry in the final matriculation examinations has led to calls for the topic to be taught better and highlighted the need for teacher professional developmen...
Chapter
Full-text available
Rubrics are increasingly used to differentiate the quality of science teachers’ pedagogical content knowledge (PCK), both qualitatively and quantitatively. Well-designed PCK rubrics can guide the judgement of PCK quality for valid assessment. This chapter considers the possibility of a “grand rubric” that allows measurement of different variants of...

Learning Study is an iterative and collaborative process that can served as the vehicle for investigating the development of teachers' topic-specific pedagogical content knowledge. The Learning Study was conducted by the researcher, three experienced Physical Science teachers and their respective supervisors who formed part of a professional learni...
Presentation
Full-text available
Learning to teach is a life-long endeavour, a learning continuum that starts at pre-service and ends when a teacher permanently leaves the profession. Teacher learning can therefore be viewed on a trajectory over the entire career of a teacher. Mapping these learning trajectories, by identifying the events that played a role, investigating the rout...

Pedagogical content knowledge, PCK, is well established in the education research community. There is general consensus that PCK is knowledge unique to teachers and different from but supported by content knowledge, CK. This study examines the performance of graduate teaching assistants (chemistry subject matter specialists) in relation to teachers...
Chapter
Full-text available
In this chapter we explore an important dimension of teacher knowledge, called pedagogical content knowledge (PCK). PCK is specialised knowledge about the content to be taught possessed only by teachers.

Full-text available
The history of South Africa presents a story of a divided education system with policies deliberately designed for disparity in the quality of provision. Prior to 1994, education policy in the country was used to constrain political, social, and economic development of people of colour, who are in the majority. Twenty years on, the widespread after...

Full-text available
In science education, learner-centred classroom practices are widely accepted as desirable and are associated with responsive and reformed kinds of teacher beliefs. They are further associated with high-quality Pedagogical Content Knowledge (PCK). Topic-Specific Pedagogical Content Knowledge (TSPCK), a version of PCK defined at topic level, is know...

Full-text available
Since the independence era in the 1950s and 1960s, many African countries have recognised the important role that science plays in the socio-economic development of any country. As a result, various African governments have enacted policies and allocated a large proportion of their gross national product to the science and science education sector...
Conference Paper

The construct of Pedagogical Content Knowledge, PCK, is now well established in the education research community. Since the phrase was first coined, multiple understandings of the construct have emerged, but there is general consensus that PCK is knowledge unique to teachers and different from, but supported by content knowledge, CK. In this stu...

Chapter
This chapter deals with research on teaching and learning in access courses. Teachers at the higher education level (and therefore on access programmes as well) face many challenges. They generally have had no teacher training, and hence very little preparation for teaching large classes. They also tend to focus on disciplinary content with little...

This paper presents a theoretical model of students' thought processes when preparing for, and executing, laboratory tasks and reporting on these. The model draws from three theoretical constructs: situated cognition, communicative competences and procedural knowledge in science. The model is constructed from empirical data and is used as a way to...
Article
In practical sessions students lack sufficient time or opportunity for deep processing of information. If the signal to noise ratio is too low, it can obscure the 'chemical message' which the lecturer is trying to convey. This study reports on an action research driven attempt to improve on a Hess's Law experiment, well known in most first year cur...
