- Description: According to Rosken & Rolka (2006), learning mathematics through visualisations can be a powerful tool to explore mathematical problems and give meaning to mathematical concepts and relationships between them. “Visualisation can reduce the complexity of mathematical problems when dealing with a multitude of information” (p.458). This case study focused on using GeoGebra as a visualisation tool to teach angle properties in Grade 9 geometry. This study set out to analyse how GeoGebra visualisations can be used by selected teachers to teach for conceptual understanding. The research is based on a constructivist view of learning and is oriented within an interpretive paradigm. The methodology used is a qualitative case study. The study was conducted in one school and involved 3 mathematics teachers who were purposefully selected because they showed willingness to use technology in their teaching. I used classroom observations and interviews to collect the data. The study identified a number of factors from the participants that related to using GeoGebra in teaching for conceptual understanding. These include the effective use of dynamic visuals to build on prior knowledge, using multiple representations through image generation and image transformation to make connections and using visuals to justify mathematics ideas. The results from this study indicated that GeoGebra can indeed be used effectively as a teaching tool to teach for conceptual understanding in mathematics.

- Description: This case study was conducted at a secondary school where I teach, situated in the semi-rural setting of Bukalo village in Namibia, and sought to gain insights into the nature and role of visualisation processes employed when selected grade 11 learners interacted with selected geometry problems. According to Mariotti and Pensci (1994), visualisation takes place when "thinking is spontaneously accompanied and supported by images”, and helps students to understand the problem at hand. Visualisation is regarded as "making the unseen visible and imagery as the power to imagine the possible and the impossible” (Mason 1992). The study is located within an interpretive research paradigm in order to obtain in-depth understanding of the participants’ visualisation processes. Within this paradigm, both quantitative and qualitative approaches were adopted. The eight Grade 11 participants engaged with 12 items of the Geometry Visualisation Tasks (GVT) worksheets. Data was collected using video-recorded learners’ interactions with the GVT, observations, stimulated recall interviews and post-GVT interviews with the learners. During the data analysis stage, I used inductive analysis to determine patterns evident in learners ‘thinking processes’. My analytical framework consisted of indicators that were used to identify and classify visualisation processes for each task of the GVT for each participant. I adapted this framework from Ho (2010) and Ho, Ramful and Lowrie’s (2015) clarification of the representations. The findings from this study revealed that the use of visualisations facilitated meaningful learning when learners made use of these to develop and scaffold their conceptual understanding. The findings revealed that most learners used visualisation processes fairly to very accurately when solving geometry problems. They used visualisation processes by using sketches and diagrams that transformed a mathematical problem pictorially, connected their thinking to previous knowledge and experience, clarified the algebraic task and assisted them to understand the spatial relationships within each task.

- Description: Textbooks are a universal and central element of teaching and learning mathematics (Namibia. Ministry of Education [MoE], 2008). Steenpaß and Steinbring (2014) state that diagrams in mathematics textbooks are often used as Visualisation Objects (VOs) to enhance learning of mathematical concepts. VOs in textbooks are thus important teaching and learning tools (Fotakopoulou and Spiliotopoulou, 2008). This Namibian interpretive case study analysed the nature of VOs used in the three approved grade 9 Namibian mathematics textbooks namely: y=mx+c to success, Maths for Life 9 and Discover Mathematics 9. The VOs were analysed by using an analytical framework adapted from Fotakopoulou and Spiliotopoulou (2008). This analytic tool was specifically used to interrogate the following categories: the type of VOs, the roles of VOs, the relation of VOs to mathematical content, the relation of VOs to reality, and their properties. The 266 VOs under study were collected from the Algebra and Geometry chapters of each book. This study also included survey questionnaires with the 50 selected mathematics teachers, which sought their views and perceptions on the use of the identified VOs. In addition, the authors’ rationale in selecting the identified VOs used in their textbooks was sought through interviews. This research study is part of the “Visualisation in Namibia and Zambia” (VISNAMZA) project which seeks to research the effective use of visualisation processes in the mathematics classroom in Namibia and Zambia (Schäfer, 2015). It is hoped that this study contributes towards improving the quality of textbook evaluations, and design of suitable and more comprehensive assessment procedures in Namibia. It is also hoped that it creates a critical awareness of the roles of VOs in textbooks amongst teachers, inspiring them to help their learners interpret VOs effectively. It should also inspire potential authors to use suitable and appropriate VOs that enhance conceptual teaching and learning of mathematics. The study discovered that most of the VOs used in the selected textbooks align well with the mathematical content. The VOs can help make abstract ideas concrete, stimulate learning, simplify and clarify written texts. In addition, VOs can also be used as a tool for reasoning and an instrument for problem solving. The findings however also indicate that some of the VOs used are not self-explanatory; they are vague, unfamiliar and confusing, leading to misinterpretations by some learners. Another interesting finding was that some of the learners found it difficult to interpret VOs on their own without the help of the teacher.

- Description: Visualisation is gaining visibility in mathematics education research. It is a powerful tool for solving different types of problems in many areas of mathematics, including Algebra - the mathematical domain of this study. The aim of this case study was to analyse the visualisation processes that selected senior secondary school learners used to solve a set of ten algebraic problems.The research was conducted at a secondary school in the Erongo region of Namibia. This is the school where the researcher is teaching. The sample consisted of six selected learners, three from Grade 11 and three from Grade 12. The learners were purposefully selected to participate in this study based on their mathematics performance in class and their willingness to participate. The participants were video recorded as they worked through the ten items of an Algebraic Visualisation Tasks (AVT) worksheet. They were also interviewed about the visualisation processes they employed when solving each of the tasks. The AVT, the videos and the interviews were analysed with the aid of an adapted visualisation template. The findings of the study show that learners used visualisations in all their problem-solving processes. These visualisations were used for different purposes such as starting points, for illustrative purposes, as organizational tools and as simplification tools. Visualisations as starting points were used when the problem was wordy and had lengthy descriptions and explanations. Illustrative visualisations enabled learners to articulate in their own way mathematical notations, mathematical equations and expressions that they then used to solve the problem. Organizational pictures provided a useful structural framework for solving the problems.This research suggests that the selected participants indeed used visualisation processes to solve algebraic problems. It is thus important for teachers to harness this aid and make the most use of these visualisation processes when teaching Algebra.

- Description: Measurement is acknowledged to be a critical component in mathematics education and is particularly important for vocational Engineering students, for whom this is a key skill required in the workplace. The goal of this research was to explore the existing measurement conceptualisations of vocational Engineering students at the outset of their course, as evident in their engagement with mediated measurement tasks. The focus on students’ prior knowledge in measurement, was for the value that this awareness holds in understanding the learning needs of the students. Students participated in five measurement tasks. Four took the form of dynamically assessed task-based interviews, and the fifth was a written test assessing what they had learned during their Mathematics classes. Domains of measurement that were assessed in these tasks included length, area, surface area, volume and flow rate. The interviewer took the role of mediator and students were assessed according to the number of moments of mediation and the degree of mediation required to successfully complete the task. Students’ responsiveness to this mediation provided insight as to their conceptualisations of the measurements relevant to the task. This research was exploratory in nature and adopted an open and flexible approach to the data analysis. Critical incidents were identified and coded according to the mediation offered and the actions of the students during the measuring activity. This allowed patterns to emerge that revealed stable and emerging conceptualisations that related to embodied and symbolic aspects of measurement. Evidence was found that for many of these students the link between the embodied and symbolic aspects of the concept was broken. This insight allowed suggestions to be formulated about how better to facilitate these students’ learning of measurement.

- Description: The reform and transformation of education systems in terms of enhancing Science, Technology Engineering and Mathematics (STEM) education in the schooling systems is gaining momentum in different parts of the world. It is argued that there is a need to enhance science education, particularly in Africa, because science education is considered to be the main vehicle through which the greater objectives such as national development and improvement in the quality of life can be realised. Namibia as a country is no exception. A key way through which science education can be enhanced is through carrying out practical activities during teaching and learning. Despite the crucial role that practical activities play in science subjects, it appears that they are not carried out in most of the Namibian science classrooms. It is against this background that this study explored an intervention on how easily accessible resources to carry out hands-on practical activities in science, influenced science teachers’ conceptual development and dispositions towards the use of practical activities in science. In this study, a mixed methods case study approach underpinned by an interpretive paradigm was adopted. The research was conducted with 21 in-service science teachers from schools in Namibia who were all on a two year part-time BEd (Honours) program delivered in Namibia by a South African university from the Eastern Cape. To generate data, document analysis, questionnaires, semi-structured interviews, an intervention in the form of workshops on practical activities, lesson observations, which were videotaped, as well as teacher reflections were used. Conceptual development, disposition and professional development served as the conceptual lenses. Vygotsky’s sociocultural theory in conjunction with Shulman’s pedagogical content knowledge (PCK) were the theoretical frameworks adopted in the study.The findings showed that there was a general perception among the participants before the intervention that in order to carry out practical activities, well-equipped laboratories, conventional chemicals and equipment are needed. Some teachers had never used practical activities in their science classes with a range of constraints or hindrances provided as reasons. The findings additionally showed that for teachers to use easily accessible resources to carry out practical activities in their science classrooms, they need the knowledge and exposure on how to use these resources. The findings thus showed that this professional development approach raised motivation, knowledge and the skills of the science teacher participants to include practical activities in their science lessons using easily accessible resources. A recommendation is that if teachers are given opportunities, through professional development platforms to engage in hands- on practical activities using easily accessible resources, they can be enabled and motivated to implement these in their science classrooms.

- Description: Assessment is an integral part of the teaching and learning process. Research by the Assessment Reform Group (ARG) (1999) and others has shown that assessment for learning, or formative assessment, is one of the most powerful educational tools for promoting effective learning and improving performance. Assessment for learning (formative assessment) and summative assessment form part of most national education policies and is advocated in the Namibian curricula. However, most of the focus of official programs in Namibia has been on summative assessment resulting in assessment for learning being neglected. It is against this backdrop that this study investigated science teachers’ conceptions of, and dispositions towards, the implementation of assessment for learning during science practical lessons. In this study, a mixed methods case study approach underpinned by an interpretive paradigm was adopted. The research was conducted with 25 in-service science teachers from schools in Namibia who were all on a two year part-time BEd (Honours) program delivered at NIED in Namibia by a South African university from the Eastern Cape. To generate data, document analysis, questionnaires, semi-structured interviews, an intervention in the form of workshops on assessment for learning, practical activities, lesson observations (which were videotaped), as well as teacher reflections were used. The lesson observations were conducted in two schools in the Omusati region of Namibia. The theoretical frameworks guiding the study were Vygotsky’s social constructivist theory and Shulman’s pedagogical content knowledge (PCK). The findings of the study revealed that teachers held different notions toward assessment for learning before the intervention in the form of a workshop. However, after the workshop the teachers demonstrated understanding of what assessment for learning entails and how it can be implemented during hands-on practical activities using easily accessible resources. A recommendation is that if teachers are given opportunities, through professional development platforms, to engage in hands-on practical activities using easily accessible resources and an appropriate orientation towards assessment for learning that includes model strategies they can be enabled and motivated to research and begin to implement assessment for learning in their science classrooms.

- Description: This study investigated pre-primary teachers’ perceptions of the causes of disparities in the literacy readiness of pre-primary learners. The aim was to understand the reasons that teachers ascribe to differences in literacy readiness; ways in which teachers’ understanding of the causes may relate to their practices and to learners’ literacy readiness levels. The study drew from Bernstein’s pedagogic discourse as the theoretical framing and analytical tool for engaging with the data. The participants in the study were three pre-primary teachers practising in a variety of schooling contexts. In a quest for a deeper understanding of the causes, data for the study was generated using multiple sources. Structured interviews were employed to get the teachers perceptions, while classroom observations were aimed at discovering ways in which the teachers’ points of view related to their practices in the actual classroom. An analysis of documentary evidence was carried out to understand ways in which teachers’ practices adhered to the curriculum intentions, as well as ways in which their plans and curriculum documents supported the development of the emerging literacy skills of the learners. Findings of this study indicated that teachers attributed disparities in the literacy readiness of learners to factors external to the classroom and it was found that their pedagogic practices, as a result of these perceptions, were not supportive to the development of literacy skills that are pivotal for transitioning to Grade 1. The study has implications for curriculum reform, sensitization of stakeholders and teacher training in order to ensure a solid and promising academic foundation, and consequently, a successful academic future for all pre-primary learners.

The study drew from Bernstein’s pedagogic discourse as the theoretical framing and analytical tool for engaging with the data. The participants in the study were three pre-primary teachers practising in a variety of schooling contexts. In a quest for a deeper understanding of the causes, data for the study was generated using multiple sources. Structured interviews were employed to get the teachers perceptions, while classroom observations were aimed at discovering ways in which the teachers’ points of view related to their practices in the actual classroom. An analysis of documentary evidence was carried out to understand ways in which teachers’ practices adhered to the curriculum intentions, as well as ways in which their plans and curriculum documents supported the development of the emerging literacy skills of the learners. Findings of this study indicated that teachers attributed disparities in the literacy readiness of learners to factors external to the classroom and it was found that their pedagogic practices, as a result of these perceptions, were not supportive to the development of literacy skills that are pivotal for transitioning to Grade 1. The study has implications for curriculum reform, sensitization of stakeholders and teacher training in order to ensure a solid and promising academic foundation, and consequently, a successful academic future for all pre-primary learners.

- Description: Poor learner performance in mathematics has a long-standing record in South Africa. More than two decades after attainment of democracy South Africa is still seeking ways of addressing this crisis. Research around poor mathematics points to a number of factors, however, the dominant being that South African teachers lack both mathematics content and the pedagogical knowledge to teach it effectively. Ball, Thames and Phelps (2008) refer to the knowledge to teach mathematics effectively as Mathematics Knowledge for Teaching [MKfT]. MKfT combines the knowledge of both the content with the pedagogical skills. Mathematics teachers in South Africa are said to lack MKfT to teach mathematics in ways that enhance conceptual understanding and the effect of this deficiency is felt as far back in the education system as Foundation Phase. Research suggests Foundation Phase teachers do not develop the learners’ number sense well enough to equip them with essential mathematical strategies and proficiency that would help them learn mathematics with ease and understanding. This deficit expands as learners move up the grades. My qualitative research, case study approach was employed to investigate MKfT enacted in the teaching of an expert Foundation Phase teacher, which she used while developing number sense in her Grade Two learners. A key aim is to inform fellow Foundation Phase teachers and Foundation Phase teacher educators, both in-service and in-training, of the key aspects of MKfT required in developing number sense. The study found that Foundation Phase teaching requires employment of all the domains of the MKfT to develop number sense to Grade 2 learners. These domains are complexly interconnected and interdependent and the research shows that while one needs the full set to be able to teach effectively, the expertise becomes visible in the seamless and somewhat automated interweaving of these domains. Furthermore, the research will illuminate how such seamless and automated interweaving can render the individual domains difficult to discern.

- Description: Learners’ general poor performance in science is a concern in science education. The literature mentions pedagogic strategies such as the use of practical activities and inclusion of indigenous knowledge, which are now acknowledged in various science curricula. In addition, many science educators and researchers are exploring innovative pedagogical approaches which may possibly help learners understand science better in order to improve their performance in the subject. Learners’ poor performance in science and possible strategies for improving this, are also a concern in Namibia. The Namibian national examination results (MoE, 2010-2014) revealed that the topic of Energy is one of those in which learners perform poorly. Energy is an important scientific concept that is widely used in various disciplines and it is thus problematic when science learners struggle to make sense of the scientific description of energy and related concepts. This triggered my interest to conduct a study focusing on the topic of energy. The study involved functional recasting from Systemic Functional Linguistic theory, as an intervention during my teaching the topic of energy to English second language grade 7 Natural Science and Health Education learners. The influence of the approach was investigated through the lens of social constructivism. The interpretive paradigm was adopted in order to make meaning of the learners’ experiences, during and after the intervention. Data collection instruments such as pre and post test, stimulated recall interviews, observation and learners’ journals were used. A qualitative approach was used to analyze the data. The pretest and post test results showed that a noticeable shift had occurred in learners’ understanding - the functional recasting teaching approach positively influenced learners’ sense making of energy concepts. Sense-making of energy concepts was evident in learners’ demonstrating the ability to construct and deconstruct technicality, making comprehensible output, meaningful use of gestures, scientific reasoning and asking relevant questions. The results also revealed dialogic discourse and positive attitudes as factors enabling learners’ progress. The language of learning and teaching, and negative attitudes were found to be constraining factors for learners’ progress. Functional recasting might be useful to science teachers and science teacher training programs as the finding for this study revealed that it enabled learners to make sense of energy concepts using scientific English. When using functional recasting, science teachers should consider the constraining factors and possibly avoid or minimize the impact.

- Description: In the Namibian education curriculum the topic light is offered in Grade 7 Natural Science and Health Education (NSHE) and in Grades 10, 11 and 12 Physical Science. The Namibian junior secondary certificate (JSC) Examiners’ reports for 2011 to 2013 indicate that more than 50% of learners have been performing poorly on questions on the topic light particularly on the questions related to the properties of light. Similarly, the Namibian senior secondary certificate ordinary (NSSCO) level Examiners’ reports for2011 to 2013indicate that many learners struggled to answer questions related to reflection and refraction of light. These results triggered my interest to investigate how Grade 11Physical Science learners make sense of the topic light based on their conceptions, experiences, prior knowledge as well as looking into factors that enable or constrain them in making sense of the topic light. This research was a case study of one secondary school in Namibian urban area. It was carried out with 22 Grade 11 Physical Science learners through a designed ASEI-PDSI (Activities, Students, Experiment, Improvisation-Plan, Do, See, Improve) teaching intervention to explore how they make sense of the topic light. Underpinned by an interpretive paradigm, the study tried to explore how learners make sense of the topic light through ASEI-PDSI teaching approach. Within the interpretive paradigm, a mixed method case study approach was adopted. In the context of this study the quan→QUAL design was applied. The study was informed by constructivism consisting of both cognitive and social constructivism as a theoretical framework looking into learners’ sense making, prior knowledge and social interaction as well as knowledge construction. Convenience and purposive sampling were used to select those 22 grade 11 Physical Science learners. The data were generated using tests (pre-test and post-test), questionnaires, stimulated recall interviews, lesson observations and video-stimulated recall interviews. Triangulation of data was employed to ensure validity and trustworthiness of the research findings. Prior the commencement of the study, informed consents were obtained in writing from the Director of Ohangwena Directorate of Education, school principal, Grade 11Physical Science teacher, learners as well as from the parents of the learners involved in the study. The findings of the study revealed that there was a positive shift in learners’ sense making as it was reflected by the learners’ post-test scores in comparison to the pre-test scores. The post test scores were higher than the pre-test scores. The study thus recommends for the adoption of an ASEI teaching approach to be used during science lessons in schools in Namibia for better academic improvement.

- Description: Anecdotal evidence over the years of my teaching reveals the use of code switching to be a regular practice in rural schools in the northern part of Namibia. Some recent studies focused on how Namibian teachers mediate specific science topics through code switching. However, although the 2013 Grade 10 examiners’ report and the latest (2014) Grade 7 National Standardized Achievement Test (NSAT) indicate that learners performed poorly in the important science topic Force, no literature could be found which explored this problem in Namibian science education. This triggered my interest to investigate how the use of code switching between English and Oshiwambo enables or constrains teaching and learning of the topic Force in Natural Science and Health Education (NSHE) lessons at a rural Namibian school. I accomplished this by implementing strategic code switching as an intervention in my own teaching with a class of Grade 7 NSHE learners and with the participation of a critical friend. An initial action research cycle of teaching was done in the medium of instruction (English) without any code switching and a Pre-test was then administered to assess learners understanding prior to the intervention. After this first cycle, code switching was integrated into the teaching as an intervention in the second cycle of teaching in the action research and a Post test was then administered. This research study is informed by social constructivism theory of Vygotsky (1978) with a focus on the concept of Zone of Proximal Development (ZPD) using language as a tool for mediating learning through strategic code switching as an aspect of Pedagogical Content Knowledge (PCK). The two action research cycles included me undertaking regular and in-depth reflections after my teaching of each lesson. Data were also collected through document analysis, learners’ responses to tests, lesson observation with video recording and stimulated recall interviews. The analysis of the data involved qualitative coding of data. Informed consent of all participants was sought by obtaining signed written informed consent letters from parents of learners taking part in the study, as well as from the teacher participating as a critical friend, the school governing body and the regional director of education, arts and culture. Findings from this study revealed that code switching between English and Oshiwambo as a teaching intervention influenced learners performance positively. The results reveal that when code switching, linguistic, dispositional, hands-on experience and relating abstract concepts to everyday life experience were either enabling or constraining factors for learning the concept Force. Furthermore, the study reveals reinforcement and relating abstract concepts to everyday life world as an enabling factor for teaching the concept Force, when code switching. Linguistic and time have been identified as constrain factors when teaching Force through code switching. Finally, it was evident that when teaching and learning is mediated through code switching some factors are enabling when/if present but constraining when/if they are absent. The results from this study have the potential to enhance my own teaching practice as well the practice of other science teachers in similar education contexts.

- Description: Visualisation is increasingly being recognised as having a significant role in the learning of mathematics especially when students are solving mathematical problems (Thornton, 2001). It is argued that visualisation is a powerful tool for learners to construct mental and physical representations that correctly mirror mathematical relationships and concepts. To gain a thorough understanding of the scope of visualisation, three Visual Technology for Autonomous Learning of Mathematics (VITALmaths) (www.vitalmaths.com) video clips were uploaded on mobile phones of each of the eleven participating student teachers who used them in their teaching practice. This is in cognisance of the educational potential offered by mobile phones and their current pervasiveness in the daily lives of both teachers and learners in Zambia (Zambia. Ministry of Education [M.O.E], 2013]). This study sought to investigate how VITALmaths video clips on mobile phones could be used by student teachers as a visualisation tool in the teaching of Number Sense. The videos of the lessons formed the core of my analysis. The study was conducted at four primary schools by eleven student teachers of a public university in Zambia. The study is framed as a case study and is grounded within the interpretive paradigm. The findings revealed that the student teachers’ use of the video clips in the classrooms for teaching was generally approached from two perspectives: at the beginning of the lesson or at the end. The videos were used at the beginning of the lesson as a means to introduce a topic or an idea, and at the end of the lesson to consolidate what was taught. The videos were also used to enhance the conceptual understanding of Number Sense. The findings also revealed that students encountered both enabling and constraining factors in their use of mobile phones to teach number sense. The overall findings revealed that, if well utilised, mobile phones as visualisation tools had the potential to enhance the teaching of Mathematics in general and Number Sense in particular, and therefore teachers should be encouraged to use them in their teaching.

- Description: Drawing from Pinar’s Curriculum Theory and Hallidayan Systematic Functional Linguistics theory respectively, this study investigates the relationship between Namibia’s Grade 7 English Second Language’s curriculum expectations and learners’ English literacy life histories. Located within the qualitative interpretive paradigm and life history research, this study uses learners’ written autobiographical narratives and spoken stories from narrative interviews with participants to generate data. The research site and participants were purposively selected, from the Grade 7 rural combined school classroom where many learners perform poorly as no learner in the research population at this research site performed successfully in English Second Language examinations. The study investigated whether the Grade 7 curriculum expectations ‘speak’ to the Grade 7 learners’ English literacy life histories in order to establish whether there is a correlation between the formal education English Second Language curriculum expectations and learners’ English literacy life histories. The findings for this study revealed that formal education curriculum designers and policy makers do not consider the cultural identities and backgrounds that learners bring to the classrooms. There are very few language activities, events both at home, school, and within the literate community necessary, to develop communicative competencies in these rural combined school learners. The interpersonal relationship between parents and child; learner and teacher; and children to community members do not provide favourable conditions for effective English language learning. There are very limited teaching and learning resources both at home; school; and within the immediate community to nurture and meet English curriculum demands. A further factor is that English usage is disregarded in all three contexts. Very alarming is the fact that, if the Namibian government continues to fail to put interventions in places where, schoolteachers are educated on their required role in helping to ameliorate negative learning conditions in rural school, then the education outcomes for Namibian learners specifically in English Second Language will be severely affected. This in turn makes the government aspirations towards Accessible; Equitable; Qualitative; and Democratic Education for all learners hard to accomplish.

- Description: Due to the lingering damage from the Apartheid era and Bantu education, South Africa is still battling to rectify the inequalities in schools in previously disadvantaged areas. The lack of a reading culture and very poor literacy assessment scores in these areas is cause to include even out-of-school time to help remedy these problems. This study seeks to add to the body of literature by investigating the influence of two selected out-of-school time reading programmes on learners’ reading attitudes and behaviours within the South African context. Drawing from the New Literacy Studies (Gee, 1991; Street, 1995) and the Theory of Planned Behaviour (Ajzen, 1991), this Mixed- Method approach study examined the role that two out of school reading programmes played in the development of reading behaviours and attitudes of learners from township area called Simonstown, in the Eastern Cape Province. Located within the Pragmativist Paradigm, Mixed Method Research Approach, and Explanatory Design Method as a research design, the study used pre- and post-intervention quantitative questionnaires, semi-structured interpreter-facilitated interviews, structured observations, and the out of school reading programme as an intervention to generate data. The research site and study participants were purposively selected. They included 10 learners from 2 out of school reading programmes that benefited from funding and literacy project training and support called Nal’ibali. The study was designed to evaluate the effectiveness of these out of school reading programmes in improving learners reading behaviours and attitudes, and how the OST reading programmes influenced the reading behaviours and attitudes of the parents. Findings from the data concluded that the certain factors in the OST reading programme in conjunction with the positive influence of the parents and siblings own reading attitudes had a positive effect on learners’ reading attitudes and behaviours.

- Description: Due to the lingering damage from the Apartheid era and Bantu education, South Africa is still battling to rectify the inequalities in schools in previously disadvantaged areas. The lack of a reading culture and very poor literacy assessment scores in these areas is cause to include even out-of-school time to help remedy these problems. This study seeks to add to the body of literature by investigating the influence of two selected out-of-school time reading programmes on learners’ reading attitudes and behaviours within the South African context. Drawing from the New Literacy Studies (Gee, 1991; Street, 1995) and the Theory of Planned Behaviour (Ajzen, 1991), this Mixed- Method approach study examined the role that two out of school reading programmes played in the development of reading behaviours and attitudes of learners from township area called Simonstown, in the Eastern Cape Province. Located within the Pragmativist Paradigm, Mixed Method Research Approach, and Explanatory Design Method as a research design, the study used pre- and post-intervention quantitative questionnaires, semi-structured interpreter-facilitated interviews, structured observations, and the out of school reading programme as an intervention to generate data. The research site and study participants were purposively selected. They included 10 learners from 2 out of school reading programmes that benefited from funding and literacy project training and support called Nal’ibali. The study was designed to evaluate the effectiveness of these out of school reading programmes in improving learners reading behaviours and attitudes, and how the OST reading programmes influenced the reading behaviours and attitudes of the parents. Findings from the data concluded that the certain factors in the OST reading programme in conjunction with the positive influence of the parents and siblings own reading attitudes had a positive effect on learners’ reading attitudes and behaviours.

- Description: This study explores the teaching and assessment practices used by teachers in environmental learning processes and emergent curriculum and sustainability competencies. The focus is the school subject Life Sciences in the Further Education and Training Phase. The study is based on four cases of teachers in schools in the Midlands area, in the province of KwaZulu-Natal. Lenses used to review the data included curriculum defined cognitive skills and cognitive levels to review the curriculum competencies and a systems approach to teaching and learning (Wiek, Withycombe, Redman & Mills, 2011) to review emergent sustainability competencies. This study employed qualitative methods, namely a questionnaire, stimulated recall interviews, observations (of lesson plan implementation in classrooms) and document analysis (detailing lesson plans, assessment tasks and learners’ work) to generate data. Analysis took place in four phases and included: a descriptive contextual analysis of factors influencing teaching and assessment practices; a descriptive analysis of teacher intentionality, topics, assessment planned and resources used; an analysis of emergent curriculum competencies in informal and formal assessment tasks; and, finally, a second layer of analysis describing emergent sustainability competencies in the environmental learning processes. Ethical considerations included permission for access, anonymity, participant rights and awareness of my role as cluster leader for the group of teachers involved. The study found that the nature of Life Sciences environmental topics and implementation influences the development of curriculum and sustainability competencies. Also, the choice of teaching methods influenced the emergence of particular curriculum and sustainability competencies. The findings also suggested that switching between isiZulu and English, unfamiliarity with action verbs, and the inconsistent use of higher order questions in classroom discussion, informal and formal assessment tasks might have affected success in the development of higher order thinking skills. Finally, the study revealed that environmental learning has the potential to support the development of integrated sustainability competencies. This study was driven by an interest in environmental content knowledge, teaching and assessment within the South African Fundisa for Change network of environmental educators. It is hoped that the study’s illustration of how consideration of curriculum and sustainability competencies can contribute to quality education practices in environmental learning, will be of use in this network.

- Description: This thesis reports on an action research case study into the use of a genre-based approach (GBA) in teaching the writing of explanation texts to Grade 11 learners in Ohangwena Region, Namibia. Knowledge of how to write different genres is a requirement of the Namibian curriculum, and in particular the Grade 11-12 English Second Language [ESL] syllabus. The study aimed to improve my pedagogic practice in the teaching of genre as an English Second Language [ESL] teacher. It also aimed to further develop my Grade 11 learners’ academic language proficiency in genre writing. I employed two action research [AR] cycles. The first cycle was aimed at establishing learners’ baseline proficiencies with regards to writing explanation texts. The second was then aimed at strengthening the weaknesses I identified in my first cycle. Theoretically informed by the genre and socio-constructivism theories, and following the recommended stages of the genre pedagogy cycle, I designed a GBA lesson unit comprising seven lessons. The lessons spanned a two week period. I used formative assessment to assess my learners’ activities during each lesson using marking rubrics designed in line with the structural and linguistic conventions of explanation texts. Data sources include document evidence from my learners’ pre- and post- instruction written works, my written reflections on the teaching/learning process from my research journal, my learners’ written reflections on each lesson, and the whole class closing discussion. The data revealed that, prior to the GBA intervention, while my Grade 11 learners possessed some skill in writing shorter explanations for content subjects; they lacked deep knowledge for so doing in ESL. The post GBA intervention data revealed that, by interacting with texts and working collaboratively in unpacking the features of the genre, learners were able to develop a more critical awareness of the generic and linguistic features of written explanation texts. The study concludes that learners’ genre writing skills can be strengthened through using a GBA approach in which they are immersed in the relevant text features and provided with appropriate assistance and feedback.

Exploring and expanding situated cognition in teaching science concepts: the nexus of indigenous knowledge and Western modern science

- Description: Certain teaching and learning strategies are appropriate in the context of exposing learners to modern science in situated cognition (SC) - the theory that posits that knowing is inseparable from doing - during, for example, visits to industrial operations. The distance and cost of travel, however, excludes most rural teachers and their learners from such SC exposure to Science and technology in industrial settings. To fill this gap between knowledge and practice in the curriculum experience for rural schools, this research investigated the extent to which a SC approach could be used in relation to indigenous knowledge practices (IKP) that have relevance to science teaching for rural science teachers. The study was conducted in three schools in the Zambezi Region of Namibia whereby six science teachers participated in the study. Also, to generate data from the community, the study included Indigenous community members as participants. Only three selected members from the community participated as representatives of the whole community. Essentially, the study explored and expanded possibilities for rural school teachers to use IKP as sites of SC in relation to concepts of pressure in particular and other science concepts. The research thus studied teaching practices as activity systems related to concepts in the school curriculum and the activity system of Indigenous community members. The patterns, regularities and irregularities provided the framing which was used to view SC through the lens of IKP. This framing of SC within the school curriculum was explored using cultural historical activity theory (CHAT) and Engestrom’s expansive learning cycle (ELC). The study was organized into two phases; exploration and the expansive phase. In the exploration phase, interviews, community analysis, document analysis, brainstorming, reflections and audiovisual evidence were used to generate data. The expansive stage used brainstorming, reflections, and interviews, an experimental test, audio-visual evidence, and interviews. Inductive and abductive modes of inference were used to come up with explanations of the research questions. Explanations proceeded using the frameworks of socio-cultural theory and social realism. Some findings from the data generated from the exploration phase revealed that science teachers in the schools studied do not always engage in a SC approach on account of a lack of Western modern science (WMS) resources and factors related to economic marginalization of the learners. Data generated in the same phase revealed that science teachers can engage the SC approach through embracing indigenous knowledge practices (IKP) reflecting Science whereby they can apprentice learners. Some of the other findings from the expansive learning phase show that science teachers in under-resourced schools can engage the SC approach if IK practices are used as mediational tools which can be used as models, icons/symbols, vocabulary, patterns, case studies and practical activities anchored in IKP. From the findings obtained the contribution which the study made was to come up with some methods of infusing indigenous knowledge systems in science teaching. The trend in research related to IK is more aligned to policies rather than how IK can be usefully used for the benefit of science teaching. As the study only looked into the IKP reflecting Science which the participating teachers brainstormed, it provides an insight into how and which other IK practices can be woven into WMS to encourage social transformation accommodative of Afrocentric world views which allows scientific literacy to be achieved.

- Description: This aim of this study was to explore the mediatory role of the Rhodes University (RU) / Southern African Development Community (SADC) International Certificate in Environmental Education course in developing capacity for reflexive mainstreaming of environment and sustainability education in teacher education in southern Africa. This course was a change-oriented intervention to support capacity and agency for mainstreaming environmental education across many sectors of education. The discourse of the course included environmental education and education for sustainable development and for this study this was referred to as environment and sustainability education (ESE). Environment and sustainability education is a developing notion in southern Africa and the SADC Regional Environmental Education Programme (REEP) was set up to support capacity for mainstreaming ESE. ESE was one of the responses taken by the SADC region to respond to prevalent environment and sustainability issues across the region. This study focused, in general, on establishing the mediatory roles of the reflexive mediatory tool, the change project in the course. More specifically, the research explores the mediatory role of course interventions and activities that were used to develop understanding of and to frame the change project in fostering agentially motivated changed practice in the teacher education sector. Drawing on realist social theory, which is a form of critical realism, especially the work of Margaret Archer, the study used the principle of emergence to interpret changes in the course participants' practices. The study was framed using the research question: How do mediated actions in a regional professional development programme and the workplace influence Environment and Sustainability (ESE) competencies, practice, learning and agency in Teacher Education for Sustainable Development (TESD) change projects? The following sub-questions refined the study: • What mediated actions on the course influence ESE competences, practice, learning and agency on the professional development programme? • How do these identified mediated actions influence ESE competences, practice and learning on the professional development programme? • What mediated actions in workplaces influence ESE competences, practice, learning and agency in the change projects in teacher education institutions? • How do these identified mediated actions in workplaces influence ESE competences, practices and mediated actions in the workplace? Notions of practice, agency, reflexivity, competences and capabilities were used to sensitise explanations of features emergent from course interactions; the process of analysis was under-laboured by the theoretical lens of critical realism and realist social theory. Mediation theory was used to explain the role of interventions across the course. The study used a case study approach with three cases of teacher educators from two institutions in two southern African countries. Data were generated through document analysis of course portfolios, semi-structured interviews with research participants, observations of participants during their teaching and through group discussions in a change management workshop to establish features that emerged from the course and change project interactions. The principle of emergence recognises that any interactions result in new features of characteristics that are different from the original. In this case, the study investigated those features shown by participants after being exposed to the course's mediatory tools. In order to describe the cases, a narrative approach was used. The study was conducted at the interface of the United Nations Decade of Education for Sustainable Development (UNDESD) and the Global Action Plan for Education for Sustainable Development, therefore the outcomes have implications for capacity development for ESE during and beyond the Global Action Plan for Education for Sustainable Development. The key finding is that capacity development for ESE needs to foreground reflexive engagement with one's own practice for it to be meaningful and relevant. The change project provided course participants with the opportunity to engage with their own practice and particularly their competences and capabilities through its mediatory tools. Course participants showed emergent properties that were evidence of expanded zones of proximal development (ZPD) in competences, capabilities and agency. The study illustrates that meaningful learning happens when immersed in context and when learners are able to make connections between concepts, practices and experiences (their praxis). The study also illustrates that capacity building creates opportunities for practitioners to expand their repertoire through the course activities. Some of the course activities stimulated, enhanced and gave impetus to their agency or double morphogenesis for them to continue to expand that repertoire by trying and retrying changes in practice that they value on their own and in communities of practice. Capacity development courses need to be structured to involve a variety of mediatory activities as some of these are relevant and are valued for different teacher education contexts. The study also shows how knowledge and understanding of classical Vygotskian mediation can be used to frame and structure courses for developing the ZPD retrospectively and how the repertoire which forms the ZPD has potential to be expanded and to keep expanding, whether at individual level or in community with others, as an object in the post-Vygotskian mediation process. The change project provides the starting point, the vehicle and momentum to teacher educators to critique and to reflexively transform competences or aspects of their practice that they value. The study showed that capacity development through the change project generated momentum for potentially morphogenetic changes in teacher education practice. The course initiated interactions at the phase T2-T3 that disrupted teacher educators' habitus. On-course phase activities such as assignments, lectures, discussions, practical tasks, excursions and regional knowledge exchange groups contributed smaller morphogenetic cycles to the main cycle. Reflexive engagement with one's own practice becomes a useful tool for building capacity for scaling capacity for mainstreaming ESE during and after the Global Action programme for ESD. Contributions of the study therefore go beyond the SADC region to contribute insights into capacity development for ESD in similar conditions of teacher education across the world.

- Description: The Namibian Senior Secondary Certificate Examiners’ Reports (2013) shed light on the topics in which learners often perform poorly and evolution is one of such problematic topics. Anecdotal reasons include religious views of teachers, opposition by learners to the topic, and inadequate understanding of the subject content knowledge. I have not come across any literature on evolution in Namibia that formally look closely at this problem. We do not have a clear idea of what is going on in Namibian science classrooms, when evolution is taught. We do not have a clear idea of the factors at play in the teaching of evolution in these classrooms, either when it is done well and completely or when it is not so. It is against this background that I was inspired to engage in this study which examined teachers’ conceptions, dispositions and pedagogical strategies that they use when teaching evolution. The study is underpinned by an interpretive paradigm, which afforded me an opportunity to understand the teachers’ worldviews in relation to evolution. It also allowed me to gain insight on the pedagogical strategies that teachers use when mediating learning of the topic of evolution and its related concepts. Within the interpretive paradigm, a case study approach was adopted, using a mixed-method design generating both quantitative and qualitative data. Teachers from two regions, namely, the Hardap region and Khomas region, participated in the study. Data were generated using questionnaires, semi-structured interviews and lesson observations. Fifteen questionnaires were completed and from those questionnaires, the sample included six teachers (40%) from the Hardap region while nine teachers (60%) were from the Khomas region. For the interview, the sample included two teachers - one from each region. For the observations, I observed five teachers teaching evolution. I presented quantitative data in tables and graphs, whereas the qualitative data was analysed inductively using Vygotsky’s (1978) socio-cultural theory as a theoretical framework. In addition, I used Ogunniyi’s (2006) Contiguity Argumentative Theory (CAT) as an analytical framework. These theories were used as lenses to interpret and make sense of the qualitative data, which I colour coded to form sub-themes. Thereafter, overlapping sub-themes were combined to form themes, which were linked to the research questions and in relation to literature/theory. Similarly, overlapping themes were combined to form analytical statements. It emerged from the study that religious views did not play a large role in most teachers’ views and attitudes towards the teaching of evolution. Instead, it emerged that lack of content knowledge on evolution is the main factor that influences teachers’ views and attitudes towards teaching evolution in schools. This is quite profound, as the assumption is that when teachers are religious, the likelihood is that they would object to the teaching of evolution. In light of this, the study recommends that there is a need for professional development and support of science teachers, so that they are able to properly mediate the learning of evolution.

Fifteen questionnaires were completed and from those questionnaires, the sample included six teachers (40%) from the Hardap region while nine teachers (60%) were from the Khomas region. For the interview, the sample included two teachers - one from each region. For the observations, I observed five teachers teaching evolution. I presented quantitative data in tables and graphs, whereas the qualitative data was analysed inductively using Vygotsky’s (1978) socio-cultural theory as a theoretical framework. In addition, I used Ogunniyi’s (2006) Contiguity Argumentative Theory (CAT) as an analytical framework. These theories were used as lenses to interpret and make sense of the qualitative data, which I colour coded to form sub-themes. Thereafter, overlapping sub-themes were combined to form themes, which were linked to the research questions and in relation to literature/theory. Similarly, overlapping themes were combined to form analytical statements. It emerged from the study that religious views did not play a large role in most teachers’ views and attitudes towards the teaching of evolution. Instead, it emerged that lack of content knowledge on evolution is the main factor that influences teachers’ views and attitudes towards teaching evolution in schools. This is quite profound, as the assumption is that when teachers are religious, the likelihood is that they would object to the teaching of evolution. In light of this, the study recommends that there is a need for professional development and support of science teachers, so that they are able to properly mediate the learning of evolution.
