Problem-based approach to mathematics in grades 9 and 11 in the Limpopo Province
Teachers of schools in the central region of the Limpopo Province of South Africa received training in a problem-based approach to the teaching and learning of mathematics and introduced these principles into their classes. Follow-up visits to schools took place on a monthly basis for one year. 800 learners in Grades 9 and 11 completed the Study Orientation Questionnaire in Mathematics (SOM). Mean age in Grade 11 was 17.5 yr. (SD = 1.4), and in Grade 9, 15.1 yr., (SD = 1.2). The differences between the post- and pre-test marks for the two groups were compared. The means for marks in mathematics were significantly different for the two groups.
