- Description: The primary objective of this study was to assess the pattern of change in neurocognitive performance for adolescent athletes on baseline measures of the Immediate Post Concussion Assessment and Cognitive Testing (ImPACT) test, over five consecutive years, with a view to providing an indication of the optimal interval for repeat baseline testing of high school athletes. Participants were non-clinical, predominantly South African high school athletes in the overall age range 13 to 18 years (N = 108), divided into five groups (Grades 8,9, 10, 11 and 12), and tested at five test intervals. Repeated-measures ANOVA analyses examined differences in score performance across the test intervals for each of the five composite scores of the ImPACT test (Verbal Memory, Visual Memory, Visual Motor Speed, Reaction Time, Impulse Control). For the Verbal Memory, Visual Memory, Visual Motor Speed and Reaction Time composites there were significant neurocognitive score changes between several test intervals. Taking these results into account, in conjunction with substantial variability in performance, it is concluded that there is a need for annual baseline testing throughout the high school years. The secondary objective was to generate normative tables (Means and Standard Deviations) on the ImPACT test for the five participant groups at each of the five test intervals, including data for: the five composite scores (Verbal Memory, Visual Memory, Visual Motor Speed, Reaction Time, Impulse Control); for the twelve subtest scores test that go to make up the composite scores; and for four additional memory subcomponent scores (Word Memory immediate recall, Word Memory delayed recall, Design Memory immediate recall, Design Memory delayed recall). The results provide a clinical and heuristic normative platform for future use with brain injured individuals, which can be used to facilitate clinical interpretations of postconcussion assessments.

- Description: The National Curriculum Statement (R-12) calls on all Natural Sciences teachers to integrate local or indigenous knowledge (IK) into their lessons. However, this seems to be easier said than done. For instance, in my experience as a Natural Sciences teacher I have observed that the Department of Education does not adequately equip and support teachers with the necessary pedagogical skills to integrate IK in science lessons. It is against this background that this study sought to explore an intervention on the development and implementation of model lessons on features of the moon that integrate local or IK in Grade 4 classes. The study adopted a qualitative case study approach underpinned by an interpretivist perspective. Within the interpretive paradigm, a qualitative case study approach was employed. The participants were four Grade 4 Natural Sciences and Technology teachers from selected schools in the Chris Hani West District. Data were gathered and triangulated using questionnaires, semi-structured interviews, document analysis, a presentation by an expert community member, workshop discussions and journal reflections. Vygotsky’s socio-cultural theory and Shulman’s pedagogical content knowledge (PCK) were used as a theoretical framework and analytical framework respectively. From the socio-cultural theory, three concepts were used: social interactions, mediation of learning and the zone of proximal development (ZPD). Additionally, within PCK, Mavhunga and Rollnick’s (2013) five Topic Specific Pedagogical Content Knowledge components: learners’ prior knowledge, what is difficult to understand, curricular saliency, representations and conceptual teaching strategies were used as analytical tools. A thematic approach to qualitative data analysis was adopted, to come up with sub-themes in relation to my research questions. The findings from this study revealed that before the intervention, some teachers had a narrow understanding of local or IK and how it could be integrated in their lessons. As a result, some teachers had never implemented integration of local or IK as required by the Curriculum and Assessment Policy Statement (CAPS) and the principles of the National Curriculum Statement. The findings of this study thus showed that after the intervention, teachers felt equipped with understanding of local or IK. Additionally, they were able to develop their own model lessons that integrated it. The study thus recommends that teachers should be supported as far as possible in order to be able to integrate local or IK in their science lessons.
