Mamombe, Charles; Mathabathe, Kgadi C.; Gaigher, Estelle – African Journal of Research in Mathematics, Science and Technology Education, 2022
This qualitative case study explored how exposure to Process-Oriented Guided Inquiry Learning (POGIL) improves 11th grade physical sciences learners' competency in solving stoichiometry problems. Two township schools of low socioeconomic status in Pretoria, South Africa, were conveniently and purposively sampled. Two classes (N = 48) composed of…

Botha, Hanlie; van Putten, Sonja – African Journal of Research in Mathematics, Science and Technology Education, 2018
Mathematical literacy (ML) is a compulsory subject in South Africa for those learners who choose not to do mathematics to Grade 12 level. ML is designed to enable a learner to become a self-managing person by providing opportunities to analyse and solve real-life problems through the mathematisation of contextual situations. The subject thus lends…

Kazeni, Monde; Onwu, Gilbert – African Journal of Research in Mathematics, Science and Technology Education, 2013
The study aimed to determine the comparative effectiveness of context-based and traditional teaching approaches in enhancing student achievement in genetics, problem-solving, science inquiry and decision-making skills, and attitude towards the study of life sciences. A mixed method but essentially quantitative research approach involving a…
