The aim of this study was to evaluate the problem solving proficiency of Physical Science learners in Highveld Ridge East circuits in Mpumalanga Province of South Africa. The objectives of this study were to determine the relationship between proficiency in conceptual and algorithmic problem solving, to compare the percentage of algorithmic and conceptual problems that were correctly and incorrectly answered, problems not attempted at all and finally to categorize Physical Science learners according to their stoichiometry problem solving proficiencies. The target population for this study was Grade 12 Physical Science learners in Highveld Ridge East and West circuit in Mpumalanga Province of South Africa. To achieve the aim of this study and its subsequent objectives random sampling was used to select the three schools and the sample after a stoichiometry achievement test was administered by Physical Science teachers, who were teaching the participants at their respective schools. The researcher scored the tests using a memorandum.
The results of this study indicated that learners’ proficiency in both algorithmic and conceptual problem solving was low, there was a weak positive correlation between algorithmic and conceptual problem solving proficiency, the percentage of solutions that were correctly solved was the lowest compared to the percentage of incorrect solutions and problems not attempted. The other result of this study was that there were no grade 12 Physical Science learners with high algorithmic and high conceptual abilities, a few learners had high algorithmic and low conceptual abilities and the majority of the learners had low algorithmic and low conceptual problem solving abilities. This implies that Physical Science teachers in these circuits should focus on developing both algorithmic and conceptual problem solving strategies when teaching stoichiometry. / Science and Technology Education / M.
