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…

Students' graph comprehension may be affected by the background of the students who are the readers or interpreters of the graph, their knowledge of the context in which the graph is set, and the inferential processes required by the graph operation. This research study investigated these aspects of graph comprehension for 152 first year…

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…

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…

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.…
