- Description: Globally, many students show a poor understanding of concepts in high school physics and lack the necessary problem-solving skills that the course demands. The application of Newton’s second law was found to be particularly problematic through document analysis of South African examination feedback reports, as well as from an analysis of the physics examinations at a pair of well-resourced South African independent schools that follow the Independent Examination Board curriculum. Through an action-research approach, a resource for use by students was designed and modified to improve students’ understanding of this concept, while modelling problemsolving methods. The resource consisted of brief revision notes, worked examples and scaffolded exercises. The design of the resource was influenced by the theory of cognitive apprenticeship, cognitive load theory and conceptual change theory. One of the aims of the resource was to encourage students to translate between the different representations of a problem situation: symbolic, abstract, model and concrete. The impact of this resource was evaluated at a pair of schools using a mixed methods approach. This incorporated pre- and post-tests for a quantitative assessment, qualitative student evaluations and the analysis of examination scripts. There was an improvement from pre- to post-test for all four iterations of the intervention and these improvements were shown to be significant. The use of the resource led to an increase in the quality and quantity of diagrams drawn by students in subsequent assessments.

- Description: The implications of nostalgia often strike a discordant note in post-apartheid discourse and this has opened up critical possibilities for research scholarship. For instance, Jacob Dlamini’s memoir Native Nostalgia entered the discursive fray in 2009, and it was subsequently followed by Derek Hook’s psychoanalytical approach in (Post) apartheid Conditions: Psychoanalysis and Social Formation in 2014. Notably, there is not yet a sustained and intensive research focus that has been conducted on post-apartheid forms of nostalgia within the discipline of art history and visual culture. I present this dissertation as a response to this gap. This thesis identifies mainly two competing nostalgias in post-apartheid South Africa. Through the analysis of selected artwork and media imagery, this dissertation critiques the connections of these nostalgias to the representation of the black figure in post-apartheid visual culture and the implications thereof. I argue that nostalgias for an apartheid-colonial-imperialist past operate through erasure and in the sanitisation of memory and as a result they render suffering indiscernible or in a sadomasochistic way consumes suffering as enjoyable. This thesis simultaneously critiques art work and visual representation that responds to South Africa’s nostalgia for the future: a restorative nostalgia that has emerged in the form of “rainbow nationalism”. This is a form of nostalgia that is underpinned by a dogged commitment to triumphalism and as a result erases the ongoing scenes of abjection. I use nostalgia and Afropessimism as analytical frameworks to argue that both real and visual representational forces work in tandem to restrain the future and this, I suggest is fulfilled by the transference of the black body from one state of unfreedom to next, resonating with a cyclical pattern. Frantz Fanon’s (1967) Black Skin White Mask forms the conceptual bedrock of my study, particularly his visual layout of “negrophobogenesis” and colonial temporality, which he describes as a “hellish cycle” or as an “infernal cycle” wherein the past overwhelms the present and ideas of the future.

- Description: This book showcases the diversity of ways in which urban residents from varying cultural contexts view, interact, engage with and give meaning to urban nature, aiming to counterbalance the dominance of Western depictions and values of ur-ban nature and design. Urban nature has up to now largely been defined, planned and managed in a way that is heavily dominated by Western understandings, val-ues and appreciations, which has spread through colonialism and glob-alisation. As cities increasingly represent a diversity of cul-tures, and urban nature is being increasingly recognised as contributing to residents' wellbeing, belonging and overall quality of life, it is important to consider the numerous ways in which urban nature is understood and appreciated. This col-lection of case studies includes examples from Africa, Asia, Europe, North and South America, and reflects on the multi-dimensional aspects of engagements with urban nature through a biocultural diversity lens. The chapters cover several themes such as how engagements with nature contribute to a sense of wellbeing and belonging; the implications that diver-sity has on the provision, design and management of urban environments; and the threats inhibiting residents’ abilities to engage meaningfully with nature. The book challenges the dominant discourse, Western ideological understandings and meta-narratives of modernisation and unilineal urban transi-tions. A timely addition to the literature, Urban Nature: Enrich-ing Belonging, Wellbeing and Bioculture offers an alternative to Western ideological understandings of nature and values and will be of great interest to those working in human and environmental urban ecology. It will also be key reading for students in the relevant fields of anthropology, development studies, geography, social ecology and urban studies.
