    An investigation of Grade 6 learners’ conceptual understanding of task words and subject terminology in Natural Science and Technology formative assessments on the topic ‘Electric circuits’
    (University of the Witwatersrand, Johannesburg, 2023-09) Soloman, Bridgette; Padayachee, Kershree; Mandikonza, Caleb
    The purpose of this study was to gain insights into grade 6 learners conceptual understanding of the task words (used in Bloom’s taxonomy) and key words (subject terminology) in the subject Natural Science and Technology (NST). This study was motivated by wanting to understand whether the possible cause of learners’ poor performance in assessments was due to their lack of understanding of assessment questions. This was investigated through a case study conducted on 101 grade six learners at a South African primary school. Learners wrote a written test on the topic: electric circuits which was subsequently marked using a memo. Based on their scores obtained 14 learners were selected and grouped into 4 focus groups based on high, average, low scores, and a mixed group. The focus group discussions explore what were learners interpretations of the task words and subject terminology used in formative assessments. The transcripts were analysed both deductively and inductively. The data analysis revealed that grade 6 learners do not conceptually understand the task words and subject terminology used in NST formative assessments. The findings revealed that learners’ interpretations depended on their understanding of either the task word or subject terminology, that the different meanings of words in colloquial English compared to academic language influenced their understanding of words, and that learners did not know how to approach assessment questions. The implication of this study is that NST teachers need to both tap into learner prior knowledge and collaborate with English teachers to assist learners understand assessment questions. The recommendation is that more time needs to be allocated for teaching task words and subject terminologies.

    Exploration of calculation strategies in doubling and halving with grade 3 learners
    (University of the Witwatersrand, Johannesburg, 2023-03) Mtsweni, Thobile; Asvat, Zaheera Jina
    A crisis reported is that the majority of learners do not achieve development in number sense. Unit counting is the preferred method of counting, and consequently, fluency and conceptual understanding of numbers are lost. This study addresses the need for early intervention that focuses on the progression of learners towards the use of more efficient strategies. Specifically, the study aimed to explore doubling and halving strategies with Grade 3 learners through an intervention to develop learners’ calculation strategies using the adapted pre-test, intervention, and post-test from the Mental Starter Assessment Project (MSAP). The sample included 24 Grade 3 learners, which comprised a control group and an intervention group. The study employed Piaget’s theory of cognitive development, which focuses on how learners process new knowledge. Findings indicate that before the intervention, the learners in the control and intervention groups relied on counting strategies to solve doubling and halving problems, and the alternative strategies that were used were not clear. The intervention group was exposed to the various doubling and halving representations of the strategy. However, the findings show that the intervention group performed only slightly better in the strategic calculating and strategic thinking categories than the control group. These findings indicate that a shift in learning can happen, albeit slower than expected. Further research is needed across contexts and learners to indicate ways in which the intervention could be improved.
