This article reports on the implementation of a teaching approach based on Gardner's theory of multiple intelligences (MI) at a school in the Hammanskraal area in Gauteng, South Africa. The aim was to determine the impact that such an approach would have on teachers, learners and learner performance. This article discusses the implementation process and the impact thereof on learner results and conduct, as well as learners' opinion on the implementation of the MI approach in the classroom. The study showed that the implementation of a new approach should be monitored regularly and that teachers should receive ample support. An MI approach to teaching had a positive influence on learners' conduct and academic achievement. It also made learners more aware of their own strengths and weaknesses and how to overcome weaknesses. Learners indicated that they prefer an MI approach in teaching.
