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…

This study compares the scientific and alternative conceptions of energy and momentum of university first-year science students in Ethiopia and the US. Written data were collected using the Energy and Momentum Conceptual Survey developed by Singh and Rosengrant. The Concentration Analysis statistical method was used for analysing the Ethiopian…

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…

Identifying an instructional tool for merging scientific and indigenous knowledge (IK) is problematic as there is no clear guidance on how this can be achieved. Argumentation is recommended as a possible integrative instructional theoretical methodology as it imbues notions of dialogue and persuasion, while at the same time embracing the…

This study focuses on the effects of the exposure of pre-service education students (n=87) to a variety of toys used as educative curriculum material in an attempt to develop their understanding of energy. Changes in their knowledge, their confidence in terms of this knowledge, and the reasons they attributed for any changes in both their…

This paper reports on an analysis of student conceptions in responses to explanation-type questions in a grade 12 (17-18 years) South African national physics examination. We were guided in our analysis of 921 examination scripts by a framework developed by Dagher and Cossman on types of explanations in science which enabled us to understand the…

More than a thousand Grade 10 Physical Science learners from four South African provinces participated in a study that probed their conceptions of energy. The purpose was to determine the learners' conceptual resources, i.e. their initial conceptions, and identify the potentially productive resources from which they may construct physics concepts.…

This study describes how a group of grade 7 and 8 students in South Africa engaged with the notion of spatial scale in the Universe before, during and after a visit to an astronomy science centre. A limited amount of research has been conducted on this concept worldwide. Using a combination of concept maps, observations and interviews, results…

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…
