    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.

    An investigation of how a lecturer uses discussion to promote meaning making during the teaching of the topic of Excretion to 3rd year preservice Life Sciences teachers
    (University of the Witwatersrand, Johannesburg, 2023-10) Nyaloku, Malebo; Mandikonza, Caleb
    This study seeks to investigate how a lecturer uses discussion to promote meaning making during the teaching of the topic of Excretion to 3rd year preservice Life Sciences teacher. The process of meaning making includes how people understand and make sense of the content. Qualitative research was conducted to investigate how a lecturer uses discussion to promote meaning making. In this study, I used an interview and observations of video-recorded lectures on Excretion. The participant in this study is a Life Sciences lecturer at the university of the Witwatersrand. Data analysis involved watching the video-recorded lectures, transcribing them and coding transcripts to identify how discussion was used to promote meaning making and having a semi-structured interview with the lecturer responsible for teaching Excretion to 3rd year preservice teachers. The findings from this study shows that discussion promotes meaning making when students engage with the lecturer, the teaching and learning materials and with other students, which allows them to share ideas and make meaning of the intended knowledge.
