- Description: This study focuses on the use of situated learning approaches in the teaching of environmental topics in Natural Science and Health Education (NSHED) and is the first of its kind in Namibia. Although situated learning approaches, as examples of learner-centred pedagogy, are advocated in national education policies, little empirical research has been conducted in Namibia into how situated learning approaches play out in classroom practice. Therefore, the goal of this study was to find out how NSHED teachers use situated learning approaches when teaching environmental topics. The study reviews the characteristics of situated learning theory and clarifies situated learning approaches as a form of learner-centred pedagogy which is actively promoted in the Namibian schooling system. The study commences with a contextual profile of the communities around the two selected schools. This describes the socio-economic and social-ecological context in which learners are taught about environmental topics. The profile also describes the under-performance of the schools in recent national assessments, especially in relation to environmental topics in NSHED. Drawing on data generated through document analysis, semi-structured interviews and classroom observations, the study concluded that: 1. NSHED teachers both knew about and wished to create an authentic context to enhance situated learning approaches. However, their understandings and applications of situated learning tended to be basic. 2. Teachers dominated the scaffolding process and their scaffolding strategies did not enable learners to increase independence in performing. 3. Despite the use of situated learning approaches, learners’ engagement with lesson content was superficial, and the teachers did little to encourage deeper reflections or critical thinking. 4. The teachers appeared to use situated learning approaches to clarify subject content but not to encourage broader environmental understanding, action-taking and change. Based on the research findings, the study recommends that situated learning approaches be integrated into pre- and in-service teacher training with the aim of enhancing teachers’ understanding regarding the use of situated learning approaches in the teaching of environmental topics in NSHED.

- Description: Improperly managed healthcare risk waste is associated with environmental degradation due to its potential to pollute air, land and water; it also poses a public health threat due to risks to community members (adults and children) who may find themselves exposed to waste that has been disposed of improperly. Despite these obvious environmental health risks, there is little information or legislative guidance on how to effectively manage the healthcare risk waste generated by community health workers who move from house to house and do not operate out of a fixed clinic with formal waste management facilities. This poses a challenge for municipal environmental health practitioners who are mandated to ensure compliance and to monitor the management of healthcare risk waste by community home-based care facilities. This educational study looks at how the knowledge held by environmental health practitioners influences knowledge-sharing practices and management of healthcare risk waste by community health workers, and how these knowledge-sharing practices can be developed and institutionalised. The study takes an interventionist approach within the social constructionist tradition. Cultural- Historical Activity Theory (CHAT) and expansive learning provide the theoretical and methodological framework to surface systemic tensions and contradictions affecting knowledgesharing and healthcare risk waste management practices. A series of Change Laboratory Workshops using the Developmental Work Research methodology enabled a twenty-seven month expansive learning process with selected municipal employees and community health workers in a small South African city. The study found that employees (such as environmental health practitioners and waste inspectors) working in municipal activity systems knew very little about the forms and functions of community home-based care facilities in their municipality. As such, their knowledge-sharing practices about the management of healthcare risk waste were restricted and generally unsystematic, which in turn contributed to inappropriate and often haphazard healthcare risk waste management practices by community health workers. As an interventionist project, the study concluded that the participatory, expansive learning process it initiated had built knowledge-sharing networks, enabled professional boundary crossing and potentially institutionalised better knowledge-sharing practices relevant to the effective management of healthcare risk waste.

- Description: In most South African schools Grade 12 Physical Sciences learners are generally not performing well. As Examiners’ Reports reveal, they are particularly weak on the topic of electrical circuits. Because of this, the Examiners recommended that conventional practical activities and revision should be implemented to improve learners’ performance whilst they are in Grade 11. These factors contributed to the rationale of this study in using the ‘straw electricity’ analogy in conjunction with a conventional practical activity to mediate learners’ sense making of Ohm’s law. The study falls within the interpretive paradigm, whose focus is on the understanding of human world-views. Within the interpretive paradigm a qualitative case study approach was employed. It is a case study because it aimed to investigate a group of learners in a given context. This qualitative case study used purposive sampling to select participants. Various data gathering techniques were employed, namely, documents, observations and stimulated recall interviews. The gathered data was analysed so as to determine the indicators of how learners made sense of Ohm’s law. The findings of this study are that learners were able to construct new knowledge within a social context where the ‘straw electricity’ analogy, using easily accessible resources, was incorporated in tandem with a conventional practical classroom task. Moreover, the ‘straw electricity’ analogy enabled a better understanding of science concepts as it tested and supported different learning skills.

- Description: Global climate change alters climatic zones to the extent that species invasion and, in particular, invasive alien plant growth, is regarded as one of the biggest threats to ecosystem functioning. Socio-ecological adaptive management practices have emerged from these threats as opportunities in developing countries where the immediacy of poverty relief acts as a political drawcard and potential for job creation. Local workers in the eThekwini Municipality’s ‘Working for Ecosystems’ biodiversity management programme (WFE) are emerging as micro-enterprise contractors (SMMEs). The transition from worker to entrepreneur has been part of the ethos and long-term planning of the Working for Ecosystems programme at a management level with a view to economic inclusion and realising long-term sustainable livelihoods. Evidence from narratives support claims of transformative outcomes. The findings of this study show that transformation is accessed at various levels: at a management level, at a well-established SMME level and from worker-to- SMME level. These show an “articulation of learning pathways and the connections that are made without a formally structured pathway of learning being in place” (Lotz-Sisitka & Ramsarup, 2013, p. 33). The routes followed to knowledge, practice and sustainability competences by participants in Working for Ecosystems are examined within the complex constellation of material- economic, social-political and cultural-discursive structures and are conceptualised as learning pathways. To fully appreciate the evolving and multidimensional nature of the emergence of SMME practice learning in the Working for Ecosystems programme, relational ontology as a perspective was introduced, with the intention of emphasising the relationship between practice, knowledge and context. Narrative enquiry and extensive data analysis was used as the method to examine workplace learning pathways. These workplace learning pathways can be enriched by more explicitly integrating observation of local and indigenous knowledge of biodiversity in everyday work and practice. However, intermittent contractual work causes disruption in learning pathways formation and results in a lack of stability in conflict with the aims of the programme’s objectives of building capacity and robustness. Findings show that skills development in terms of workplace learning with intersecting, diverse levels of participation and knowledge flow, is particularly important for learning pathways development in the field of invasive alien plant control where divergent values, norms and levels of practice are operational. Prior knowledge, of either indigenous plants or business functioning mechanisms, scaffolds SMME skills through relevance and connected learning in the two fields of practice pertaining to the Working for Ecosystems programme. Clarity of management roles and solidarity within management enhances SMME functioning and learning pathway development for all participants. The Expanded Public Works Programmes (such as Working for Ecosystems) are examined as an opportunity for acquisition of knowledge, competence and new skills development. A prime competence for sustainability understanding is interpersonal skills as these form an essential link with most other competences and as such should be foregrounded in training and learning pathway development. Site selection and time in the programme is a critical factor for expansive learning pathways and environmental stewardship development. Ultimately, in examining and reflecting on the Education for Sustainable Development and green economy potential, it is apparent that learning pathway development needs more support to realise the possibility of entrepreneurship and its political and social significance in terms of sustainable livelihoods. There is a need to recognise diversity, multiple ways of knowing and learning, in learning pathways development “to build joint capacity to cope with complex sustainability challenges” (Wiek, Withycombe, & Redman, 2011).
