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…
