- Description: This research focused on an investigation of the pedagogy and strategies used by Grade 11 Life Sciences teachers when mediating Biodiversity concepts with English second language learners. My interest in this investigation was triggered by the Examiners’ Reports for Life Sciences from 2009 to 2012 which consistently noted learner challenges in answering, interpreting and analysing questions during exams. The reports highlighted learners’ lack of understanding of the questions which led to them providing irrelevant information in their exam scripts. These reports claimed that challenges experienced by these learners could be attributed to language issues experienced by English second language learners. Influenced by these reports, a qualitative case study of two Senior Secondary schools in East London, Eastern Cape South Africa was conducted. Underpinned by an interpretive paradigm and driven by the desire to achieve an in-depth understanding of the case under study, three phases of information gathering were followed. The first phase was that of gathering information through document analysis. Documents were analysed to gain insights and understanding of the issue before conducting interviews. The next phase was that of gathering information through semi-structured interviews followed by classroom observations. Findings from these observations were verified through stimulated recall interviews which provided clarity on the intentionality of choosing a certain method and strategy over another when assisting learners in making meaning of biodiversity concepts. The main findings of this study are that factors which limit learner understanding of biodiversity concepts are a result of a combination of factors such as failure to interpret questions, spelling problems which alter meaning of concepts and an inability to make distinctions among closely related concepts within the topic of Biodiversity. Responding to these factors, teachers demonstrated knowledge of a variety of teaching strategies to support learners. The choice of teaching strategies seemed to be guided by their experiences as well as the challenges they often encounter. Furthermore, teachers’ reflections on their practice provided opportunities for them to identify strengths and limitations of their choice of strategies and possibilities for improvement. It was also noted that factors such as large class sizes, gaps in content knowledge and a lack of detail in chalkboard summary limited the effectiveness of their teaching strategies. The study recommends that: • Teacher-learner ratio needs to be considered for effective support; • There is still a need to capacitate educators in environmental education. In-service training should focus on developing teacher understanding of foundational knowledge in life sciences; and • Teachers need to improve their chalkboard summary skills to increase the level of support that could be provided by comprehensive chalkboard summary through the elaboration of ideas

- Description: The National Curriculum of Education was implemented with the broad view of including all learners as laid out in the document Toward Education for All. The curriculum emphasised that the topic distillation should be studied. According to the Examiners Reports, the topic distillation is one of the topics where learners face difficulties in the Namibian Senior Secondary Certificate Ordinary (NSSCO) examination Grade 12. This led me to do research on understanding how Physical Science teachers mediate the topic distillation in Namibia specifically in the Kavango region. The study was carried out at two rural schools with two teachers teaching Grade 11. The community member who I asked to demonstrate the making of Kashipembe was also a participant during this study. Kashipembe is a local cultural brew alcohol beverage commonly made in the Kavango East and West Regions of Namibia, which was used as a learning context in this research study. The study used a qualitative case study underpinned by an interpretive paradigm. Data was generated through the use of document analysis, semi-structured interviews, stimulated recall interviews, lesson observations, brainstorming and practical demonstration of making Kashipembe. These different methods of data gathering were used with the aim of triangulating and validating the data. Therefore, my theoretical framework adopted Vygotsky’s (1986) mediation of learning, social constructivism and pedagogical content knowledge according to Shulman’s (1986) theory. The emergent themes were identified inductively and they were colour coded. These themes were later developed into analytic statements which were used in the study. The findings indicate that the use of community knowledge and experience during the teaching of scientific concepts like distillation is important. These findings can also be used by the practising teachers to make their teaching more effective in the curriculums where distillation is included. Therefore, the Namibian curriculum developers need to include this community knowledge in the curriculum to make it easier for the learners to make sense of the topic distillation.

- Description: This thesis reports on a collaborative action research case study with Grade 8 learners in a rural high school in Fort Beaufort District, Eastern Cape, South Africa. The goals of the case study were firstly, to understand best practices for promoting extensive reading using a classroom library, and secondly, to use these insights to put an extensive reading programme in place with a view to improving my practice as a language teacher and to gain better understanding of ways of enhancing my Grade 8 learners’ literacy skills. The following qualitative methods were used to collect data: observation, semi-structured interviews, class discussion, questionnaires, journal reflections and document analysis. Analysis of data involved identification of emerging themes and patterns. The findings suggest that the strategies used in the extensive reading intervention improved my learners’ levels of engagement with reading. Putting these strategies into practice, and reflecting critically on how to refine them helped enrich my own professional insight and development in relation to the implementation of extensive reading programmes. Since action research is usually designed in spirals of action, this research serves as a first spiral and a foundation upon which to build second and subsequent spirals (which do not form part of this research). The study highlighted the fact that certain challenges that emerged (for example, shortage of books at the learners’ level, and a lack of parental cooperation) need to be addressed in a second spiral of intervention. The study further suggested that the implementation of effective extensive reading programmes by teachers in the middle and upper phases of secondary schooling requires further investigation.
