  • Mixed Context Based Teaching: A Student Centric Pedagogy to Teach Physical
           Science in High School Classroom

    • Authors: Pinaki Chowdhury, Mmushetji Rankhumise, Olivia Neo Mafa-Theledi, Sibongile Simelane-Mnisi
      Pages: 57 - 62
      Abstract: The purpose of this study is to investgate mixed content based teaching using a student centric pedagogy to teach physical science in high school classroom. Mixed Context Based Teaching (MCBT) was developed as an alternative pedagogy. MCBT in Grade 10 classrooms was investigated in the Nkomazi municipal region of South Africa’s Mpumalanga province. Despite a lack of resources at the school, MCBT was found to increase Chemistry teaching learning outcomes. In this study MCBT was used to teach chemistry content of physical science. The developed pedagogy uses a controlled dialogic method combined with context and analogy to teach. Present study used a mixed method of data analysis. Pre-testing and post-testing was used in this quasi-experimental investigation. In this study, quantitative data was collected and used for finding the answer for the research questions even though we used an exploratory sequential mixed-method research design. There were two distinct groups. A control group and an experimental group were created. A control group consisted 31 students and an experimental group had 50 students. Pre-test and pot-test data were collected from control group as well from experimental group. It also included four in-service teachers as co-researchers. They assisted in the administration of pre-tests and post-tests, as well as observing the class delivery process. Teachers who took part in the study returned to their schools and incorporated MCBT in their classes. The lead researcher watched the participating teachers’ lessons using a refined teaching observation procedure. After working on MCBT deployment in classrooms, these teachers provided a collection of qualitative data. An analysis of quantitative data using z-stats, showed statistically significant differences in the performances between control and experimental groups. The study found that a hybrid context-based pedagogy was beneficial in enhancing Chemistry teaching and learning results in rural schools with limited resources. Any technology-based teaching technique could be costly, however MCBT has no financial costs other than the training of participating teachers. The observations of this study opens an opportunity to adopt an improved teaching-learning method for underdeveloped and developing countries’ rural poor country sides, where finances are a barrier to enhancing Chemistry teaching-learning outcomes.

  • The Impact of Nurturing Talent in A Science, Engineering and Technology
           Programme on Learner Performance in Physical Science

    • Authors: James Tlhabane, Mmushetji Rankhumise, Olivia Neo Mafa-Theledi
      Pages: 100 - 108
      Abstract: This paper investigated the impact of the Nurturing talent in Science, Engineering and Technology (NSET) programme on teaching practices in rural schools within the Nkowankowa cluster in the Limpopo Province. Though NSET programme focused on Science, Mathematics and Technology, this study will only concentrate on Physical Sciences. Out of the population of 68 Science teachers, 30 participated in the completion of questionnaires and nine were interviewed. A mixed-methods approach with an exploratory design was used in this study to investigate the impact of the NSET programme on learner performance in Physical Sciences (focusing on teacher content and pedagogical delivery). For learners to consistently perform better, then one need to focus on teacher development in terms of content and pedagogy. The model that focuses on teacher development in order to address the performance of learners helps to sustain better results at school than focusing directly on learners since the teachers are likely to interact with more learners and stay at the same school longer. Questionnaires, interviews and document analysis were used as data collection methods. According to the research findings, the NSET programme had a positive impact on both the content and pedagogical delivery of teachers. This was revealed through the confidence educators gained and their ability to come up with new teaching strategies and improved teaching practices. The positive impact of the NSET programme is also noted through learners’ improved academic performance in Physical Science. The NSET programme conducted within the Nkowankowa cluster yielded positive results and the Limpopo Department of Basic Education (DBE) can adopt it as one of the best practices in the development of teachers and improvement of results in their schools.
