This study aimed at exploring the understanding of concept inventories for classroom assessment by physics tutors and pre-service teachers in selected diploma teachers' training colleges in Tanzania. The study employed a qualitative research approach and a case study design. Eight physics tutors and 20 second-year pre-service physics teachers from…

Problem-based learning (PBL) is considered to be an effective teaching and learning strategy as it leads to longer retention of concepts learnt, improves problem-solving skills and enhances critical thinking. However, teachers often find it difficult to implement as they do not receive guidance during their initial training. A professional…

In physics education, assessments address various forms of scientific knowledge. Most of the existing test instruments emphasise the assessment of content knowledge. These tests fail to measure the epistemic aspects of science. Thus, assessing epistemic knowledge is a theme that demands investigation. This study applies Rasch analysis to help…

There is a scarcity of studies that focus on how South African high school physical sciences teachers are grappling with chemical laboratory safety (CLS). This is despite the fact that the Curriculum and Assessment Policy Statements in the South African school system increased emphasis on laboratory activities in the physical sciences. Department…

The discussion on how to integrate African indigenous knowledge (IK) into mainstream Science and Technology schooling prevails. Nigeria's colonised school curriculum is antithetical to its rich IK heritage. Guided by postcolonial theory, and the need for a culturally relevant and decolonised curriculum, this paper sought to explore seven basic 7-9…

The study is part of a larger project concerned with addressing the problem that Eritrean science teachers face in their attempt to implement a new learner-centred science curriculum. Specifically, the study attempted to determine the effects of the use of an Argumentation-Based Instructional Model (ABIM) on 25 pre-service science teachers'…

In an exploratory study, 36 South African physical science teachers' understanding of basic concepts concerning electric and magnetic fields was studied from a perspective of possible concept confusion. Concept confusion is said to occur when features of one concept are incorrectly attributed to a different concept, in the case of this study to…

This case study analyses teachers' presentations made during a professional development workshop on the implementation of learner-centred science teaching in Lesotho secondary schools. Teachers revealed their understanding of learner-centred teaching through products such as pictures, diagrams, stories including metaphors and letters. These…

The force concept in physics is known to be poorly understood by high school and university students throughout the world, with alternative conceptions being prevalent. In this study, I surveyed the conceptions regarding force of a large and varied convenience sample of South African physical sciences teachers, and sought patterns between levels…

In pursuance of one of the goals of the new South African curriculum to integrate science with Indigenous Knowledge Systems (IKS), this study, which forms part of a larger study, is concerned with determining teachers' and learners' conceptions of a number of familiar natural phenomena. Several recent studies have indicated that: (1) learners do…
