The use of guided inquiry-based learning (GIBL) in a manner designed to challenge individual students' unscientific conceptions of science, has been researched widely. However, few (if any) studies have investigated the implementation of GIBL in a manner designed to challenge the fundamental patterns of students' context-dependent unscientific…

Ndihokubwayo, Kizito; Uwamahoro, Jean; Ndayambaje, Irénée – African Journal of Research in Mathematics, Science and Technology Education, 2020
Effective teaching of physics requires the use of well-designed and diversified instructional tools such as multimedia throughout the teaching and learning process. The main objective of this study was to investigate the effectiveness of Physics Educational Technology (PhET) simulations and YouTube videos to improve the learning of optics in…

Kaheru, Sam J.; Kriek, Jeanne – African Journal of Research in Mathematics, Science and Technology Education, 2016
A study on the effect of the use of computer simulations (CS) on the acquisition of knowledge and cognitive load was undertaken with 104 Grade 11 learners in four schools in rural South Africa on the physics topic geometrical optics. Owing to the lack of resources a teacher-centred approach was followed in the use of computer simulations. The…

Stols, Gerrit; Long, Caroline; Dunne, Tim – African Journal of Research in Mathematics, Science and Technology Education, 2015
The purpose of this study is to apply the Rasch model to investigate both the Van Hiele theory for geometric development and an associated test. In terms of the test, the objective is to investigate the functioning of a classic 25-item instrument designed to identify levels of geometric proficiency. The dataset of responses by 244 students (106…

Dimitriou-Hadjichristou, Chrysoula; Ogbonnaya, Ugorji I. – African Journal of Research in Mathematics, Science and Technology Education, 2015
This paper reports a study on the effect of using the Lakatosian heuristic method to teach the surface area of a cone (SAC) on students' achievement according to Bloom's taxonomy levels. Two groups of students (experimental and control) participated in the study. The experimental group (n = 20) was taught using the Lakatosian heuristic method…
