- Description: This study investigates the possible effects that construction play (in the forms of guided play and guided play with exploratory talk) using the ‘6 Bricks’ approach has on the development of learners’ visual perception and reasoning abilities. The intervention, which aimed at developing visual perception, required the participating teachers to use the ‘6 Bricks’ approach three times a week over a period of six months. The sub-set of teachers in the intervention group who were also expected to facilitate discussion to promote reasoning abilities were tasked with additional ‘6 Bricks with exploratory talk’ activities once a week spread over ten weeks during the intervention period. The study followed an explanatory sequential mixed-method design with pre-post-testing using comparison and experimental groups to generate both quantitative and qualitative data. The sample included Grade 2 teachers and their learners in five purposively selected schools in Port Elizabeth, South Africa. Quantitative data were generated via pre-post-analysis of two tests, namely, the Visual Perceptual Aspects Test (VPAT) and Raven’s Coloured Progressive Matrices (RCPM) test. Statistically significant improvements were found in the experimental group’s pooled VPAT subtest scores as opposed to only three for the comparison group’s VPAT subtest scores. Statistically significant improvements in mean scores were achieved by some schools in the exploratory talk experimental group for the RCPM test. Qualitative data, obtained from teacher record sheets, researcher’s observations and semi-structured, open-ended teacher interviews were triangulated against the quantitative data. The findings, when considered in light of the literature, suggest that the ‘6 Bricks’ approach can contribute to the development of learners’ visual perception. In the instances when using the ‘6 Bricks’ approach with exploratory talk was implemented successfully, improvements in learners’ reasoning abilities were observed.

- Description: This study investigates the possible effects that access to selected multiple representations (words, arrows and colours) have in terms of cognitive load and learner achievement when presented with algebraic problems at grade nine level. The presentation of multiple representations (the intervention) was intended to decrease extraneous cognitive load, manage the intrinsic cognitive load (algebraic problems) and optimise germane cognition (schema acquisition and automation). An explanatory sequential mixed-method design was employed with six hundred and seventy three learners in four secondary schools. Quantitative data were generated via pre-, intervention and post-tests/questionnaires, while qualitative data were obtained from open-ended questions in the pre-, intervention, and post-tests/questionnaires, eight learner focus group interviews (n = 32), and four semi-structured, open-ended teacher interviews. Statistically and practically significant improvement in mean test scores from the pre- to intervention test scores in all schools was noted. No statistically and practically significant improvement was noted in further post-tests except for post-test 2 which employed more challenging problems (statistically significant decrease with a small practical effect). Learners expressed their preference for arrows, followed by colours and then words as effective representations. Teacher generated qualitative data suggests that they realise the importance of using multiple representations as an instructional strategy and implicitly understand the notion of cognitive load. The findings, when considered in the light of literature on cognitive load, suggest that a reduction in extraneous cognitive load by using a more effective instructional design (multiple representations) frees working memory capacity which can then be devoted to the intrinsic cognitive load (algebraic problems) and thereby increase germane cognition (schema acquisition and automation).
