Item Open Access Barriers to effective science teaching and learning in secondary schools in grade twelve(2012-12-19) Tsiga, George; Mutshaeni, H. N.; Kaheru, S. J. M.Item Open Access Management of high school learners academic performance in Chemistry(2017-09-18) Nesengani, Alidzulwi Thomas; Mashau, T. S.; Kaheru, S. J. M.; Kutame, A. P.Performance of learners in Chemistry in South Africa has been below the international average. This study intended to investigate the management of high school learners’ academic performance in Chemistry as a component of Physical Science. The study employed mixed designs which are qualitative and quantitative. The population of this study comprised learners who were doing Physical Science, Physical Science teachers and school principals. The principals as participants were purposively sampled whereas teachers and learners were stratified random sampled. Data were collected through questionnaires which were distributed to learners and teachers, while school principals were orally interviewed. Data obtained from questionnaires were analysed using SPSS software. Qualitative data were analysed through identification of themes, development of codes and sub-themes. The improvement of teaching and learning will have a positive impact on the academic performance of high school learners in Chemistry. The findings showed that there are factors which affect the management of high school learners like (school location, inadequate physical resources, attitude and anxiety) contribute to the performance of learners in Chemistry. The findings also showed that factors influencing the academic performance of learners in Chemistry like (effective teaching, In-service Training of Chemistry teachers and Chemistry syllabus and content) contribute to the performance of learners in Chemistry. This study will give new insight to curriculum developers and implementers, and researchers regarding emerging issues on performance and influence the Ministry of Basic Education on policy formulation. Improved Chemistry performance will give learners opportunities to pursue science related courses in higher institutions of learning and middle level colleges.Item Open Access The role of subject advisors in supporting mathematics educators in the further education and training band with regards to pedagogical content knowledge(2015-02-11) Maudu, Mukhethwa Isaac; Litshani, N. F.; Kaheru, S. J. M.Item Open Access The significance of outsourced science teachers on learner academic performance: An educational management perspective(2020) Nesane, Mmbengwa Alfred Nesane; Ramabulana, L. P.; Kaheru, S. J. M.This study explored the significance of outsourced Science teachers on the learners’ academic performance. The focus was on academic performance of learners in Physical Sciences in Limpopo Province and outsourced teachers from other countries continentally and abroad. The research population constituted all learners, outsourced teachers, parents, school managers and curriculum advisors involved in Physical Sciences in Limpopo Province. Purposive random sampling was used to obtain 1200 learners, 80 outsourced Science teachers, 40 parents, 40 school managers, and 16 curriculum advisors, all from 8 of the 10 newly demarcated districts of Limpopo Province. Three conceptual frameworks, namely, Structural Functionalism, Social Constructivism and Community of Practice coherently underpinned the study. This qualitative study used document analysis as well as face-to-face (individual) and focus-group interview schedules that were semi-structured to solicit data from the participants. Trustworthiness was guaranteed through Guba’s model of trustworthiness of qualitative research study. Data was processed, summarized and analyzed, through thematic analysis. The following research questions guided the study: What is the significance of outsourced Science teachers on the learner academic performance? What are the factors that influence outsourced Science teachers to teach effectively? What are the challenges faced by outsourced Science teachers and how do they deal with them? What model could be created which schools can envisage for insourced teachers to use? The study revealed that more than 75% of schools that performed well in 2018 Grade 12 Science from all the ten districts of Limpopo Province are manned by outsourced teachers. Several other reasons attributable to the academic achievement together with the challenges that outsourced Physical Sciences teachers face in their trade were revealed by the study. The study recommended that collaborative work approach among stakeholders to bring about good results.
