    A critical review of academic practice and integrated edtech use at a South African University: The ‘real’ level
    (University of the Witwatersrand, Johannesburg, 2023-06) Hoosen, Nazira; Agherdien, Najma; Abrahams, Lucienne
    This study aimed to investigate and understand how academics’ digital competence and critical digital pedagogy (CDP) knowledge shaped pedagogical practice. Freire (1970), Bhaskar (1978), Archer (1995) and Shulman (1987) were the main authors drawn upon in the literature. A qualitative research paradigm and a multiple case study methodology were employed by drawing on critical realism (CR) and social realism (SR) as a theoretical analytical framework. This entailed exploring structural, cultural and agential emergent properties to examine how each construct developed over time prior to synthesis. The analysis demonstrated that the form of agential mediation to which academics were exposed explained why some of them in the same social structures and culture enacted CDP practices, while others did not. Consequently, three crucial dimensions of CDP knowledge and enactment were made visible through this study’s data and theoretical analytical framework, namely digitally-enabling structures, digitally-informed cultures and digitally-capable agency. From a pragmatic perspective, to enact CDP practice, academics need to connect the digital reality to knowledge work and epistemic practice. In this process, academic agency and digital agency would intersect, requiring reflexive and reflective practice. However, while reflection assists in recognising the need for CDP knowledge and enactment, it is insufficient on its own: embodied action and mindful critique of the world are required. From a theoretical perspective, the concept of ‘critical’, in the literature, is related mainly to the level of social relations. This study demonstrated that there is a socio-cultural stratum and a psychological-cognitive stratum. Both these strata need to be considered as mechanisms that interact with each other to produce the outcomes of CDP practice within a digital reality. Collectively, these contributions do not translate to accepting the digital reality as a predestination. Instead, it highlighted that academics functioned in a layered HE system that required, not a singular, but a unified and pluralistic (collective) vision. Individuals and institutions are limited in their capacity to respond proactively to external change and internal complexity. Therefore, the HE system requires a rerouting from the traditional path, critically reframing learning and teaching through transformative foresight, where all parts within the system work co-terminously. One significant outcome of this study is a developmental higher education systems thinking framework focusing on the promotion of CDP practices.

    Socio-technical factors impacting youth perspectives on digital transformation in resource-constrained environments: A study of Diepsloot youth
    (University of the Witwatersrand, Johannesburg, 2023-06) Matanda, Lorraine; Ochara, Nixon Muganda; Abrahams, Lucienne
    There has been a proliferation of tech hubs in Africa, with more than 80 in South Africa, forming a foundation for more inclusive digital innovation. However, we do not sufficiently understand the relationships between tech hubs, digital inclusiveness and poverty. This study explores the sociotechnical factors influencing access and use of the Internet to achieve social inclusion in resource-constrained environments. The literature reviewed focused on social influences on digital adoption, tech hub infrastructure, digital skills, and trends in Information Communication Technologies (ICT) policies. The study’s findings are categorised into themes using the sociotechnical systems (STS) theoretical framework. Each of the seven STS theoretical components (goals, culture, people, processes, infrastructure, technology and environment) were used as a lens to explore the social and technical factors that influence the perspectives of the youth on digital transformation. These themes were then mapped to the four dimensions of the research questions (social influence of digital adoption, institutional infrastructure for access, digital skills, and ICT policies for digital enablement) to highlight key findings and interpretations of the study. Under social influences, the youth demonstrated resilience driven by a need to improve their standard of living in a challenging environment. The institutional infrastructure, designed to support youth to access digital technologies, is constrained by a lack of resources. Tech hubs are using creative ways with the limited resources to cater to all their patrons, although there is room for improvement. In terms of digital skills, four youth profiles are highlighted to demonstrate a solid existence of digital skills and pursuit of tangible outcomes among the youth. In addition, the youth want to pursue entrepreneurship, meaning that tech hubs can potentially become mass training centres for digital entrepreneurship. Finally, a review of ICT policies revealed a chasm between the ICT policy objectives and activities on the ground, pointing to a lack of implementation and monitoring of ICT policies. Acting as a platform for digital foundations, tech hubs in marginalised environments must engage policymakers and reinforce their role in digital empowerment to influence policy development. This research is located in the qualitative interpretivist paradigm. A total of 21 in-depth interviews were conducted with 18 youth, with an equal representation of male and female, and three tech hub managers. Based on the researcher's analysis, access to the Internet offers the resilient youth a view into "a new world" that make them feel they can achieve anything they want. The high literacy level among the youth puts them in good stead for digital upskilling, and they are motivated to participate in the digital economy. However, ICT policy objectives concerning universal access look good on paper, but in reality, poor people are still offline. They are still excluded.

    The effect of digital transformation on the business models of solutions providers: A perspective on South African firms
    (University of the Witwatersrand, Johannesburg, 2023-08) Moodley, Andrew Jaycee; Abrahams, Lucienne
    In this interdisciplinary study, we examine the global shift of commercial models from ownership to as-a-service in technology, which forms the foundation for the solutions provider product and service capabilities. The democratisation of digital technology access paves the way for new players and diverse competitors in their landscape. Investigating deeper, we uncover four dimensions—servitisation, entrepreneurship, sustainability, and open innovation—that exert significant influence on the business models of South African the solutions provider. The research problem gains meaning through the lens of the dynamic capabilities framework. Rooted in social constructivism, the researcher explores interactions and connections that foster the creation of knowledge and meaning. To understand the solutions provider category comprehensively, the researcher conducted one-on-one interviews with various industry experts, including vendors, systems integrators, telecommunications operators, resellers, independent software vendors, and enterprise customers. This process unveils that a pivotal element in achieving successful digital transformation lies in adopting an alternative business model that facilitates continuous adaptability. This study showcases how organisational ambidexterity lenses equip these companies with the ability to create, deliver, and capture value. Internally, servitisation and entrepreneurship empower the solutions provider to redefine their intellectual property and leadership strategies. Externally, sustainability and open innovation emerge as levers they employ to ground responsible transformation and elevate value propositions. The research emphasises that these providers must focus on developing intellectual property as their core offering. This involves leadership cultivating the adaptive skills necessary to facilitate effective collaboration. Furthermore, giving precedence to digital sustainability emerges as an enabler in shaping the persona of the solutions provider as an innovative company. Ultimately, this study establishes the fundamental role of the solutions provider as a catalyst for enterprise digital transformation, enriching our theoretical understanding of this category.
