This study investigates the development of Topic-Specific Pedagogical Content Knowledge (TSPCK) of 14 novice uncertified graduate science teachers during a Professional Development Intervention (PDI) on teaching particulate nature of matter. TSPCK was defined in terms of five knowledge components: learner prior knowledge, curricular saliency,…

Growing class sizes and the rapid advancement of information technology have prompted institutions to implement blended learning in their academic offering. There are few reports in the literature on a holistic assessment of the effectiveness of the instructional design of blended learning courses for large classes. We defined effectiveness from a…

This study describes multilingual students' authentic use of their multiple languages in a science classroom in Viljoensdrift, South Africa. There has been a broad scope of research conducted by several researchers with regards to translanguaging and all have proven it to be an effective pedagogical tool that can be used in the process of teaching…

Scientific inquiry has been advocated as a common curriculum goal in school science education in South Africa, and also throughout the world. In South Africa, the introduction of inquiry-based instruction in a reformed science curriculum has met with serious challenges, such as the under-preparedness of in-service teachers. The purpose of this…

This paper analyses the current state of postcolonial and decolonial science teaching, based on a systematic review of the literature, with a special focus on the European context. It shows that currently, a very narrow view on postcolonial science teaching prevails, limiting its scope to former colonies. A total of 227 articles published…

This paper elaborates a process followed to characterise manifestations of cognitive regulation during the collaborative planning of chemistry practical investigations. Metacognitive activity was defined as the demonstration of planning, monitoring, control and evaluation of cognitive activities by students while carrying out the chemistry task.…

This article describes the development and validation of an instrument that can be used to assess students' perceptions of their learning environment as a means of monitoring and guiding changes towards outcomes-based education. In the first phase, data collected from 2638 Grade 8 science students from 50 classes in 50 schools in the Limpopo…

Pre-service teachers enter initial teacher education programmes with conceptions of teaching gleaned from their own schooling. These conceptions, which include teachers' beliefs, may be resistant to change, which is a challenge in contexts where teacher educators hope that teachers will teach in ways different from their own schooling. Conceptions…

This paper discusses the nature of learner engagement with science content during small group discussions in which learners use their home languages. We observed that learners reverted to their home languages in small group discussions, yet very little is known about the dynamics of learner engagement when they use their home languages in…

Investigates the intuitive beliefs held by students (N=2326) about a number of well-known physical events. Finds that the context of the question has a clear effect on the frequency with which different options are selected in physically similar situations. (DDR)

The new South African curriculum known as Curriculum 2005 (to depict the year of its full implementation) requires that teachers integrate school science with Indigenous Knowledge Systems (IKS). Curriculum 2005 has generated heated debates at various levels since its inception in 1997. This study focuses on the effectiveness or otherwise of a…

In response to the needs of a newly democratic South Africa, a new education policy required science teachers to integrate Indigenous Knowledge Systems (IKS) with school science: Curriculum 2005 (C2005) was developed. The first phase of that curriculum was implemented in 1997 with the hope that by 2005 it would have been implemented in the entire…

The aim of this research was to develop a model of factors affecting students' ability to interpret external representations (ERs) in biochemistry. The study was qualitative in design and was guided by the modelling framework of Justi and Gilbert. Application of the process outlined by the framework, and consultation with relevant literature, led…

This article reports on a phenomenographic-based study of the expectations of teaching among undergraduate physics students. Data are drawn from a range of course-contexts at each of two quite different universities--one South African and one Swedish--and five qualitatively different expectations of physics teaching are identified and exemplified.…

Reports on the assessment of student background knowledge along a continuum of language dependency using a set of three probes. Examines improved student performance in each of the respective assessments on the extent to which a sound natural history background facilitated meaningful learning relative to English as Second Language (ESL)…
