| Summary: | This mixed methods research design, which was modelled on the
constructivist view of schooling, sets out to investigate the effect of developing
mathematical problem solving skills of grade 8 learners on their performance
and achievement in mathematics. To develop the mathematical problem
solving skills of the experimental group, a problem-centred teaching and
learning environment was created in which problem posing and solving were
the key didactic mathematical activity. The effect of the intervention
programme on the experimental group was compared with the control group
by assessing learners’ problem solving processes, mathematical problem
solving skills, reasoning and cognitive processes, performance and
achievement in mathematics. Data were obtained through questionnaires, a
mathematical problem solving skills inventory, direct participant observation
and questioning, semi-structured interviews, learner journals, mathematical
tasks, written work, pre- and post- multiple-choice and word-problem tests.
Data analysis was largely done through descriptive analysis and the findings
assisted the researcher to make recommendations and suggest areas that
could require possible further research. === Mathematics Education === M. Ed. (Mathematical Education)
