- Description
- Physical Science is one of the subjects in which learners perform poorly in most Namibian schools. For instance, in ║Kharas region where the study was conducted, from 2010 to 2016, the overall performance has ranged between 20-40%. Furthermore, according to the results analysis report from the Directorate of National, Examination and Assessments (DNEA), from 2012 to 2016, the ||Kharas region was ranked 11th, 12th, 13th, 14th and 10th in the regional rankings. From the Examiner’s reports, the most poorly answered questions in the National Senior Certificate examinations are those that require learners to explain and show understanding. Additionally, the reports highlighted that learners lack practical skills or lack exposure to experiments and demonstrations to enhance their understanding (Namibia, 20142015). It is against this background that this study sought to explore how teachers mediate learning of experimental techniques using fermentation and distillation of a traditional brew. In particular, the study addressed the following sub-questions:1) what are Grade 11 Physical Science teachers’ perceptions and experiences on the inclusion of indigenous knowledge during Science lessons? 2) What factors influence Grade 11 Physical Science teachers’ perceptions and experiences on the inclusion of indigenous knowledge? 3) How do Grade 11 Physical Science teachers teach experimental techniques conventionally- fermentation and distillation? 4) How does the inclusion of a practical demonstration on making Ombike enable or constrain Grade 11 Physical Science teachers when explaining concepts on experimental techniques - fermentation and distillation? Thus, the focus was on conceptual understanding through linking content to the context of the learners. The study was underpinned by an interpretive paradigm whose focus is on understanding people’s worldviews. Within the interpretive paradigm, a mixed methods (Quant-QUAL methods) case study approach was employed in two sequential phases with Physical Science teachers at one secondary school in Keetmanshoop. Data were collected using document analysis (to strengthen my context). In the first phase, a questionnaire with closed-ended and open-ended questions was used to gather quantitative and qualitative data from 17 Physical Science teachers. Additionally, I conducted interviews with two Physical Science teachers from one Secondary School in Keetmanshoop who were selected based on their expertise, teaching experience and their qualifications. Quantitative data were analysed using frequency tables and graphs. For phase two, lesson and the practical demonstration observations were videotaped and transcribed inductively. Thematic analysis was used to analyse the qualitative data. The study was informed by Vygotsky’s (1978) socio-cultural theory with a focus on the mediation of learning, social interactions and learner engagement within the learners’ Zone of Proximal Development (ZPD) in conjunction with Shulman’s (1987) theory on pedagogical content knowledge (PCK). The findings of the study indicated that the majority of the Physical Science teachers were aware of and supported the inclusion of IK; on the other hand the teachers indicated some challenges that come with IK integration. Some teachers acknowledged the importance of IK, such as the enhancement of understanding, proving of theories, and arousal of interest and context relevance. However, some teachers felt that there are misconceptions in IK that can be carried into the classroom, IK resources like textbooks are not available, and IK is not integrated in the syllabus and examinations and lack of teacher training inter alia.The study recommends that the Ministry of Education, Arts and Culture especially the Division of Curriculum Planning and Development (NIED) needs to explicitly include IK in the Syllabus documents and suggest the inclusion of IK in the textbooks to the publishers to address these challenges. In order to enhance the teaching and learning with IK in Science, it is critical that teachers’ training workshops are conducted and IK resources are designed so that IK integration can be successfully implemented. For that to happen, it is recognized that the teachers’ PCK should be regularly upgraded through Continuous Professional Development (CPD) by the Subject Advisors (SA) so that the teachers are consistently guided on appropriate teaching methodologies and pedagogies about the inclusion of IK.
