- Description: The aim of this study was to assess whether ambient-air pollution contributed negatively to ambient-air quality, and subsequently to human health in the Nelson Mandela Bay Municipality (the study area). A research design that is descriptive and explorative in nature was followed. The research methodology conformed to the following procedure. Firstly, an emission inventory of one hundred and fifty (150) emission sources listed on the data base of the Nelson Mandela Bay Municipality was compiled (“N” and “n” = 150) in a quantitative research approach. Emission data from these sources, together with the relevant meteorological data from the weather stations in the study area (“N” and “n” = 5) were collected and used as input into a geographical information system-software program to quantify the contribution of each emission source to ambient air pollution. The said software program was also used to simulate the dispersion of emissions over the study area. The emission inventory was compiled in consultation with a focus group of experts in the field of air-pollution control in a qualitative-research approach. Secondly, health records of the patients who attend the clinics in the said municipality (“N” and “n” = 49) were assessed for air pollution-related health outcomes. Nineteen (19) of the forty-nine (49) clinics were situated in Sub-District A; fifteen (15) clinics were situated in Sub-District B. The last fifteen of the clinics were situated in Sub-District C, which was also the least-industrialised sub-district. Sub-districts A and B were found to be the most industrialised of the three Sub-districts. Air pollution related health statistics were compiled for the following air-pollution-related health outcomes, namely: lower respiratory tract infections in children under five (5) years of age, as well as pneumonia and asthma in the general population.

- 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.
