Towards Integrating Education for Sustainable Development at Initial Teacher Training: The Case of Lesotho College of Education
This viewpoint paper presents some findings of a participatory action research programme carried out by teacher trainers at the Lesotho College of Education (LCE) in order to integrate education for sustainable development (ESD) into its courses. It reveals how social learning brings about deep meaning as students connect subject content knowledge through participatory learning to their sociocultural backgrounds. Participants were later interviewed to ascertain their views on teaching for sustainable development and on interdisciplinary collaboration as a means of enhancing quality in teaching and learning. The findings indicate that some participants had, as a result of the action research project, been able to emerge from the culture of academic isolation through initiating collaboration with other teacher trainers outside the study area.
Emergence of Environment and Sustainability Education (ESE) in teacher education contexts in Southern Africa : a common good concern
Environmental and sustainability issues prevail in modern society. Southern Africa, where this study is based, is one of the regions most at risk from intersecting issues of climate health risk, and poverty-related ills. Education has the potential to facilitate catalytic transformation of society through development of understandings of these intersecting environment and sustainability concerns, and to support engagements in more sustainable social practices oriented towards the common good. This requires a rethinking of education within a wider common good frame. It also has implications for how quality education is considered. However, little is said of how this could be done, especially in teacher education. The paper shares two cases of teacher educators’ change project experiences, as they emerged via professional development support and the mediatory processes applied in courses conducted by the Southern African Development Community Regional Environmental Education Programme (SADC REEP) aimed at enhancing professional capacity of teacher educators and other environmental educators for mainstreaming environment and sustainability education (ESE). These courses are framed using a change project approach, and involve teacher educators as main participants. In-depth data were generated from interviews with two teacher educators, their assignment write-ups, and observations of their teacher education practice. Realist social theory, particularly the principle of emergence, was used to trace the emergence of change in teacher education practice. Sociocultural learning theory was used to explain mediation of learning-oriented changes in teacher education practice. We illustrate how the change project model and approach contributed to mediating change in practice, showing emergent attributes of capacity for mainstreaming ESE and elements of a concept of quality education among course participants oriented towards the common good. In conclusion, we argue that ESE seems to be a sensitising construct for initiating and sustaining change for ESE in teacher education. In addition, the change project has proved to be a potential vehicle for mainstreaming the notion and practice of ESE into social systems and teacher education 1 In this paper we use the term, environment and sustainability education (ESE), to indicate that it includes an emphasis on environmental education(EE), and education for sustainable development (ESD). ESE, as used in this paper, includes a strong focus on the interrelated nature of environmental, societal, political, and economic concerns, and the way in which this term is used is oriented towards the wider common good.
Finite Difference Modeling on the Temperature Field of Substrate in Friction Surfacing
Friction surfacing is an advanced process of great potential, especially in the field of repair and reclamation of worn and damaged components. As a kind of thermal processing technology, the temperature profile and changes of the substrate in friction surfacing are important factors to get coatings of high quality. In this paper, the temperature field of the substrate during the process is simulated by finite difference method. The results are consistent with experiments, reappearing the temperature change of the substrate during friction surfacing, allowing further study on figuration and quality of coatings.
