South African universities in a time of increasing disruption

Universities face a very real threat of becoming archaic institutions that offer irrelevant programmes to the graduate of tomorrow, if they do not adapt to the so-called Fourth Industrial Revolution (4IR). The 4IR will usher in a business environment that embeds the use of technology to disrupt and challenge conventional thinking and practices, forcing new business models that utilise different skill sets. It is therefore expected to cause major changes in society, and equipping graduates from institutions of higher learning to meet these demands will require a fundamental rethink of how curricula are designed to meet this challenge. The COVID-19 (Coronavirus Disease 2019) pandemic will accelerate these changes at a rate that was not anticipated even a few months before the spread of the virus to South Africa in early 2020. Thus, this article considers developments in curricula from selected top-tier universities vis-à-vis the 4IR, while also considering how the teaching and learning environment is set to change in a post-COVID-19 world. The findings will inform management within South African universities.


Introduction
Universities face a very real threat of becoming archaic institutions that offer irrelevant programmes to the graduate of tomorrow, if they do not adapt to the so-called Fourth Industrial Revolution (4IR). The 4IR will usher in a business environment that embeds the use of technology to disrupt and challenge conventional thinking and practices, forcing new business models that utilise different skill sets. It is therefore expected to cause major changes in society, and equipping graduates from institutions of higher learning to meet these demands will require a fundamental rethink of how curricula are designed to meet this challenge. The COVID-19 (Coronavirus Disease 2019) pandemic will accelerate these changes at a rate that was not anticipated even a few months before the spread of the virus to South Africa in early 2020. Thus, this article considers developments in curricula from selected top-tier universities vis-à-vis the 4IR, while also considering how the teaching and learning environment is set to change in a post-COVID-19 world. The findings will inform management within South African universities.

Background to the problem and purpose of the study
The pace of technological change is faster today than ever before in human history and this is reflected in the education sector. The World Economic Forum (WEF) (2016) estimates that nearly 50% of subject knowledge acquired during the first year of a four-year technical degree will be outdated by the time the student graduates. They further state (2016:3) that '65% of children entering primary school today will ultimately end up working in completely new job types that don't yet exist'. Drivers such as a more flexible working environment, mobile internet, cloud computing, big data, the internet of things (IoT), a sharing economy, robotics, artificial intelligence, and automation will revolutionise the working environment of the future (WEF 2016). The change will potentially be, as Bhalla et al. (2017) state, 'a tidal wave of change … that will soon make the way we work almost unrecognisable to today's business leaders'. Effectively, they argue, dramatic change will become the norm: 'In an age of rapidly evolving technologies, business models, demographics, and even workplace attitudes … change is not only constant but also exponential in its pace and scope'.
Universities must be responsive to this. In particular, the curricula they offer would need to be increasingly more dynamic and adaptable, almost, it can be argued, simultaneous to the demand for new skills dictated by the 4IR. A speedy response is, therefore, crucial in an increasingly innovative environment, but is a concern in the South African higher education environment (Rodney-Gumede 2019) where only 11 out of 26 universities have introduced modules and degree programmes responding to the skills demand of the 4IR (Pandor 2019). Moreover, given that the so-called STEM 1 (science, technology, engineering and mathematics) disciplines are sure to dominate 4IR-related content, for South African universities this is particularly concerning because schools are not providing them with entrants that have the requisite STEM skills to enter programmes dealing with 4IR-related content. Considering that 78% of Grade 4 learners cannot read for meaning (Howie et al. 2016) and 79% of Grade 6 Mathematics teachers have subject-content knowledge level lower than that of the Grade 6 learners they teach (Venkat & Spaull 2015), the quality of mathematics and science in South African public schools rank as being of the worst in the world (WEF 2017). This is exacerbated by the fact that South African universities only accept entrants into the sciences with a pass mark of above 50% in Mathematics, whereas the number of matriculants achieving above 40% in their final examinations fell almost 11% from 2018 to 2019 and reflected just over 41% of total bachelor passes in 2019 (DHET 2020). With only 29.1% and 28.7% of all university graduates eventually qualifying in the fields of science, engineering and technology in 2016 and 2018 (DHET 2018(DHET , 2019, there are clear indications of an education system with major structural concerns at the secondary schooling level. The president of South Africa has realised this and appointed a task team to focus on upskilling school learners. In the 2019 State of the Nation (The Presidency 2019c) address, he announced that a number of subjects related to technology would be introduced into the school curriculum in coming years (The Presidency 2019a). So too the Department of Basic Education (DBE) has indicated that teachers would be trained in computer skills and coding, with the latter being piloted in 1000 schools in five provinces as from 2020 (Businesstech 2019).
1.References are also often made to STEAM, where Arts are also included to incorporate, in particular, the liberal arts.
The DBE further confirmed that Robotics would be offered as a subject from Grade 9 onwards. As stated by the Minister of the DBE (BusinessTech 2019): This [the introduction of Robotics in curricula] will not only develop STEM skills, but also contribute to effectively developing children's creativity, critical-thinking, design-thinking, and digital skills [that will] ensure that South Africa develops learners who are makers and inventors who will contribute to building an innovative culture in South Africa. (n.p.) To further support this, the president announced the merger of the departments of Higher Education and Training with Science and Innovation (The Presidency 2019b). Whether or not these proposed initiatives will achieve the desired effect, given the dire state of the quality of mathematics and science teaching at school level remains to be seen.
Besides considering the practical challenges facing the South African higher education sector, the devastating effects of the COVID-19 pandemic in 2020 have challenged universities all over the world to change the way they operate. With over 80% of the world's student population affected as a result of imposed lockdowns (Sahu 2020), especially those at universities that offer a face-to-face teaching and learning environment, the use of technology has become more pervasive than ever before. This has forced universities around the world to recognise the need to adapt to technology as the only practical approach to saving the 2020 academic year (Mohamedbhai 2020). By implication, the expedited move towards a digital-based online teaching and learning environment has transpired without prior warning, and preparation and implementation has been on a largely ad hoc basis. In Africa this unplanned sudden move to digital is a particularly large problem. Tamrat and Teferra (2020) indicate that 'only 24% of the African population has reliable access to the internet', which inadvertently raises concerns regarding the quality of the teaching and learning experience (Mohamedbhai 2020). The internet penetration rate of South Africa is substantially higher than fellow African countries at 62% and, although lower than counterparts in the developed world such as North America (88%), Western Europe (92%), Northern Europe (95%) and Southern Europe (83%), it compares favourably with emerging economic blocks such as Central America (66%), Caribbean (60%), Eastern Asia (63%) and South East Asia (66%) (Datareportal 2020). Needless to say, improving access to the internet is a priority for the South African government (The Presidency 2019b).
Although COVID-19 has identified major structural concerns for universities, there is the potential to use it to implement long-term strategies that will digitalise their online teaching and learning environment in the future (Khagram 2020), and in particular to align themselves to developments in the 4IR. Universities will therefore not only have to speedily adapt to the challenges of equipping graduates for the rigours of the 4IR, but also skilling entrants from a public schooling system with structural weaknesses (Mouton, Louw & Strydom 2013). For the former, the ability of universities to incorporate new modules into curricula at a rate commensurate to the ever-evolving work environment is key to sending graduates into the workplace to meet the demands of the 4IR; for the latter, the added pressure on them to commit resources to upskill or even reskill, in particular, the STEM knowledge of incoming students from the school system. COVID-19 has at the very least provided the platform to accelerate these processes. Based on these arguments, this study focuses on the former -that is, it considers what toptier universities are incorporating into their curricula to address the rigours of the 4IR and the developments in the technology-driven space that directly affect the modus operandi of South African universities. More specifically, the article investigates the developments in curricula focusing specifically on economic and management sciences (or in a broader sense, commerce) for South African and a selected group of international universities, in order to assess what content they are incorporating to address developments within the 4IR. By comparing the developments in the South African situation with trendsetters (top-tier global universities), as well as technology-related developments, a judgement can be made as to what extent South African universities are adapting to a time of disruption that is unprecedented, especially with regard to the effect that COVID-19 has had on higher education globally.
The following structure is used: in the article the typical skill sets expected from graduates entering the 4IR, are first considered, and then the effect of Covid-19 on the high education sector. Following this, the content of curricula in leading universities is investigated in: (1) South Africa, (2) the developed world (top-tier universities in the United States and the United Kingdom) and (3) online offerings such as massive open online courses (MOOCs) to ascertain what content they include to equip graduates for the 4IR. In conclusion, the article identifies the major findings and makes recommendations for South African university management vis-à-vis developments in curricula in the broader field of commerce in an increasingly disrupted world.

Literature review The Fourth Industrial Revolution and developments in skills
The 4IR is currently one of the most commonly discussed topics among academics, researchers, practitioners and policymakers across the globe. The term 'Fourth Industrial Revolution' was initially coined during the Hannover Fair in 2011 and officially announced in 2013 as part of a German high-tech strategic initiative to take a leading role in industries that were transforming the manufacturing sector (Mosconi 2015). While its origin is not doubted, its definition remains debateable (Bauer et al. 2014 Lorenz et al. (2015) identified nine technological pillars of the 4IR, namely systems integration, big data and analytics, simulation and virtualisation, the IoT, the cloud, cybersecurity, autonomous robots, augmented reality and additive manufacturing. The 4IR is therefore a broad reference to developments in technology and its integration into everyday life. More specifically, it is 'characterized by a fusion of technologies that is blurring the lines between the physical, digital, and biological spheres' (Schwab 2016).
An important consideration is the extent of the integration -it is pervasive to such an extent that it alters, and even threatens, the traditional modus operandi in the work and personal context for humans (Bawa 2017). This suggests that the skill sets required by the future worker, and thus future university graduate, will be different to those required in the past. Rodney-Gumede (2019) emphasises that the skills and experiences that were important only three years ago, will continue to shift from being industry-specific to being transformable and centred on what he refers to as the 4Cs: collaboration, communication, creativity and critical thinking. Gray (2016:1) further argues that '35% of the skills considered important today will change as the 4IR will have brought us advanced technologies'. Skill sets will therefore not only expand, but also becoming increasingly more complex and integrated with each other, typically including complex problem solving, critical thinking, creativity, people management, coordination with others, emotional intelligence, judgement and decision-making, service orientation, negotiation, cognitive flexibility, and the management of information (Botha 2017; Rodney-Gumede 2019).
Skill sets therefore play directly into the education that future entrants into the labour force will require. Menon and Castrillion (2019) argue that university graduates must not merely receive training all-round with skills and knowledge, irrespective of the field they specialise in. Rather, due to disciplinary boundaries becoming increasingly blurred, flexibility in the curricula of qualifications would offer students 'rapid knowledge silos' and prepare them for a multifaceted and multi-disciplinary future. This, they argue, requires a holistic approach to curricula development and teaching that will empower graduates with the 'ability and agility' to adapt to the challenges of the 4IR.
The proliferation of new knowledge and the respective skills attached to it, is significant. In addition to the estimates that up to 50% of current technical curricula will be outdated by the time a student graduates, a study conducted by the WEF found that more than one-third of the respondents regarded the core skill sets of workers in 2020 to be those not considered to be important in 2016 (WEF 2016). Complex problemsolving in particular was considered to be the most important skill leading into the 4IR, followed by skills related to social, process and systems (WEF 2016). By implication, the skill set of the future requires a fusion between both traditional 'hard' skills (those associated with technical expertise) and 'soft' skills (those associated with emotive, abstract and social dynamics). Universities therefore need to adapt modules and programmes that promise to ensure their graduates are ready and qualified for both of these (WEF 2018).
Given these escalating demands placed on universities, what would the implications be on curriculum design?
Curriculum design in a changing workplace Suskie (2018) states that effective curriculum design focuses on the learning goals, and not necessarily only the content. This is an important consideration vis-à-vis the 4IR, as it places focus on not only the curriculum per se, but also the outcome of the curriculum and suggests an approach that is adaptive to changing societal outcomes. Two approaches typify this approach: backwards and competency-based curriculum design. For the former, the curriculum is designed with the skills and knowledge that the students should acquire by the time they graduate in mind; for the latter course credits are replaced with competencies. The importance of this is that curriculum design must shift from being the traditional discipline-based kind -in which knowledge forms the core of the curriculum -to being more constructivist or learningcentred -in which case the focus is on the development of the learner in changing times (Cullen, Harris & Hill 2018).
Moreover, transforming the education system through curricula redesign will increasingly be measured against how educational outcomes meet the requirements of stakeholders in the workplace (Halili 2019;Panikar, Dev & Washinton 2015). This, however, is a challenging task for educational systems (Shahroom & Hussin 2018) that will require a re-articulation of curricula within higher education (Penprase 2018). It is further exacerbated by the fact that both the nature of work and the job market are changing and will continue to change at an increasing pace (Xing & Marwala 2017). The way curricula disseminate information, as well as how students are expected to apply the information, suggests that even those studying in a field such as the humanities where the technical skills attached to, say, technology are not as prevalent, need to ensure that they at the very least understand the founding principles (if not the ethical principles) of new developments in technology (Butler-Adam 2018). By implication, Penprase (2018) suggests that education strategies must prioritise human skills to maximise the development and empowerment of graduates in an allrounded manner, focusing specifically on cultural, socioeconomic and interpersonal skills. In essence, curriculum development must equip graduates with the capabilities and skills that technology is not able to replace (Shahroom & Hussin 2018) and be designed in such a way to not only teach and develop new skills, but also to also do this as the demand for skills evolves (Hussin 2018). In doing this, not only will universities train graduates to have a mindset aimed at lifelong learning, but reposition themselves to remain relevant as long as they themselves evolve amid new developments ushered in by the 4IR (Halili 2019). This evolution will be driven by an integrated approach to curricula development (Xing & Marwala 2017) that focuses on developing the capacity of students to comprehend the impact of technological advances on humans (Bawa 2017). A more inter-and multi-disciplinary mindset will be required in which lifelong learning becomes central to developments in the job market (Hong 2017;Horowitz & White-Burke 2018).
Although the 4IR, in and by itself, is the driving force behind the disruption facing universities, the rate at which it is set to occur has been expedited due to the COVID-19 pandemic.

Disruption amid COVID-19
The novel COVID-19 pandemic, which by all accounts started in the Chinese city of Wuhan in late 2019, has rapidly spread across many countries around the world. In response, many have introduced both local and international travel restrictions and imposed strict lockdown regulations. As of the end of March 2020, over 150 countries had closed down schools and universities affecting over 80% of the world's student population (Sahu 2020). This has created a host of unexpected challenges from both the university's and the student's perspective. Many universities have been forced to rapidly transition from traditional face-to-face teaching to different forms of online delivery modes (Gewin 2020), resulting in unplanned expenditures. Also, while online teaching is not necessarily a new mode of delivery for the majority of universities, many staff members were found wanting technologically savvy and had to acquire the skills of online learning platforms without the requisite training (THE 2020). Many academic staff members also do not have the experience of designing learning material for the online environment (Bao 2020). The added pressure of working from home, while in many instances also being required to homeschool children, has added further pressure due to not necessarily having a work environment conducive to productivity (Gorlick 2020). Assessments in the online environment have created further challenges. For example, assessments developed for a face-to-face environment had to be transformed to online assessments, which have raised concerns regarding not only their quality, but also the likelihood of encouraging cheating in the online environment (Watson & Sottile 2010). Two recent examples include online cheating at the Georgia Institute of Technology and Boston University where students used the help of the education technology company Chegg to complete online assessments (Flaherty 2020). The aforesaid has thus disrupted universities in ways unimaginable before the onset of COVID-19.
Moreover, the majority of students in South Africa are reliant on the computer labs, Wi-Fi connections and libraries available on the campuses of universities. Due to many not having access to any of these at home, COVID-19 has forced them to rely on data plans provided by universities and their smartphones to attend and complete online classes and assessments (Mathiba 2020). Students who, therefore, lack access to digital devices are at a clear disadvantage, which has implications on both the grades they receive and the likelihood to defer their studies (Alruwais, Wills & Wald 2018). Furthermore, students used to the face-to-face environment require a heightened sense of self-discipline and a learning attitude conducive to online learning (Bao 2020). The speed at which students have been forced to adapt, places them under immense pressure and raises concerns regarding the value for money they get while paying for tuition that presupposes the full ambit of a traditional faceto-face teaching and learning environment (Burki 2020). With most accounts suggesting that a vaccine is expected in 2021, the reality is that universities and students will have to endure the online environment into late 2021 and, most likely, later (Le et al. 2020).

Research methods
This study adopts a non-positivist qualitative research design and specifically the case-study approach, which aims to 'build a holistic, largely narrative, description to inform the researcher's understanding of a social or cultural phenomenon … [emerging] organically from the research context' (Astalin 2013:118). Although qualitative research, and by implication a case study, adopts an 'interpretative paradigm' that may be construed as being subjective from the perspective of the researcher (Starman 2013:30), the suggested bias has been argued to be misguided as case studies, in particular, explore real-world situations 'as they unfold in practice' (Flyvbjerg 2011:309). To ensure this, and specifically scientific rigour, the results need to be unbiased, trustworthy, credible and confirmable (Guba & Lincoln 1982;Morse, Olson & Spiers 2002). As such, a documentary analysis was conducted from those available in the public domain on the websites of the chosen universities -more specifically, a 'documents as commentary approach' according to which 'insight into individual and collective … practices and structures that are not otherwise observable' was adopted (Atchan, Davis & Foureur 2017:56). Yearbooks or prospectuses from the faculties of economic, management and business sciences (or broadly speaking, commerce) were identified after which critical probing into the content (Atchan et al. 2017) allowed the content, and specifically modules within curricula, to be identified through the 'orientation of qualitative description' (Oczkowskia et al. 2018:59). The study, therefore, follows an inductive approach, typical of qualitative research designs and allows 'research findings to emerge from the frequent, dominant, or significant themes inherent in raw data, without the restraints imposed by structured methodologies' (Thomas 2006:238).
The study used a non-probability sampling design and more specifically purposive sampling. The sampling frame comprised South African and top-tier United States and United Kingdom universities. The overarching criterion used for selection was the availability of information regarding the modules in curricula focusing on degrees in commerce. Based on this, six South African universities were selected and five of the top six global universities according to the QS University Rankings. Table 1 provides the list of these universities.
At the risk of merely providing a summary of the modules in university curricula, we need to explain what is meant by '4IR-related content'. For purposes of the study, this refers specifically to modules that deal with topics within the curricula of qualifications in the field of commerce that, in the broadest sense, are expected to deal with those relating to the 4IR. Generally speaking, this includes, but is not necessarily limited to, data science, business analytics and fintech in a specifically commerce-related degree programme. More specifically this includes modules focusing on technology, the management, analysis and dissemination of information and data -including coding, programming and the like, simulation, digitalisation, machine learning, robotics, big data, blockchain, IoT, artificial intelligence and so on. A caveat on this is in order: although the yearbooks (or prospectuses) providing information on the respective modules are informative as to the name of the respective modules, and they usually provide a list of the expected outcomes, detail of the content is typically sparse. For this reason, the study does not specifically consider the content within modules themselves, but rather identifies modules that, through their names, describe content linked to topics associated with the 4IR.

Ethical considerations
This article followed all ethical standards for research without direct contact with human or animal subjects.

Findings South African universities
South African universities offer traditional commerce degrees, but have introduced 4IR-related modules as either electives or as part of the core modules. For example, at the University of Cape Town (UCT) students studying towards a BCom can specialise in 'traditional' areas including accounting, actuarial sciences, economics and management, whereas students studying towards a BBusSc can specialise in 12 areas (UCT 2018a), including analytics and information systems, dealing specifically with analytical methods pertinent to advances in the 4IR or modules more interdisciplinary by nature, such as cognitive neuroscience. At Stellenbosch University (SU) a BCom is offered in mathematical statistics with a focus on data science, focusing specifically on requiring students to gather, store, transform and graphically represent data (US 2019). In the field of business management at the University of Pretoria (UP), there have been substantial changes with the introduction of modules, such as design thinking and business innovation, business analytics (including topics such as data mining, big data and data stream analysis), and responsible leadership (UP 2019).
Universities also acknowledge the roles of both inter-and multi-disciplinary degrees with a 4IR flavour.

Top-tier universities in the United States and the United Kingdom
The composition of the bachelor's degrees offered by the toptier universities in the United States and the United Kingdom are unique. For instance, the US curricula are more flexible, orientated towards being inter-disciplinary, and emphasise a broad approach to subject content. Harvard and Stanford curricula, for example, maintain a major-minor system which allows students the opportunity to select subjects outside of their major areas of specialisation. In contrast, Oxford and Cambridge offer curricula that are more rigid and orientated towards in-depth specialisation (also called majors, concentrations or triposes) in various fields.
An interesting dimension of the curricula of Harvard, Stanford and the Massachusetts Institute of Technology (MIT) is the so-called general educational requirement (or general institutional requirement at MIT) that needs to be completed by all students irrespective of their area of specialisation. The aim of this requirement is to develop a set of essential intellectual competencies and social skills to broaden the exposure of students to a plethora of different disciplines -it is therefore multi-disciplinary at its core. For example, the content is not only spread among courses in the traditional sciences, humanities, arts, social sciences, and technology, but also covers exposure to soft skills associated with improving writing and speaking, planning, reasoning, culture, diversity, foreign languages and cultures, ethics, and belief systems to name only a few (Harvard University 2019a; MIT 2019b; Stanford University 2019c). At MIT there is even a 'physical education requirement' which entails a minimum of four physical education courses and the requirement to pass a 100-yard swimming test -the rationale being that both the body and mind need to be healthy and are not independent of one another (MIT 2019b).
The top-tier universities offer students substantial choices in the composition of their curricula. For example, although MIT awards only one undergraduate BSc degree, a major (or specialisation) is selected out of a possible 54 fields (MIT 2019a). In turn, Stanford University offers students BA, a BSc or a BA&Sc with a major from a possible 65 fields, constituting at least one-third (but not more than two-thirds) of a student's programme (Stanford University 2019a). Harvard offers more than 3700 courses in 50 undergraduate fields of studies, albeit not offering a business concentration to undergraduate students (Harvard University 2019b). Furthermore, at the University of Cambridge an undergraduate BA (Hons) degree with more than 65 subjects is offered (Cambridge University 2019). Therefore, although top-tier universities offer students considerable flexibility, balance is sought between the depth of knowledge acquired when specialising in a specific major and the breadth of knowledge acquired through broader exploration of multiple disciplines (Stanford University 2019b).

Massive open online courses, short courses and MicroMasters ®
In recent years universities have aggressively pursued the use of technology in the provision of specialised and shorter online-based programmes. Top-tier universities in particular have focused on offering MOOCs which provide free courses through partners such as edX, Coursera and Udemy. edX, for example, was formed in 2012 when Harvard joined MIT to allow an open-source online learning platform to distribute course content and other academic material of over 2 400 courses, collaborating with top-tier universities across the world. 11 As an extension of edX, mooc.org provides a database 11.See www.edx.org.
on all the available MOOCs with a substantial number of courses focusing on 4IR-related content such as artificial intelligence, big data, blockchain, computer science, cybersecurity, data science, machine learning, Python, R programming, and robotics. 12 For a nominal fee, top-tier universities offer online short courses focusing on industry-relevant content, and especially those related to the 4IR. Usually marketed as online certificate courses in either 'Executive' or 'Professional Education', these courses are typically presented in collaboration with an IT collaborator such as Emeritus, Getsmarter or Greater Learning which facilitate the entire online process, running for periods averaging 6-12 weeks.
In South Africa, universities such as UCT and SU offer similar featured online certificates on topics such as data science and fintech. 13 A further development in recent years has been the so-called MicroMaster® programmes, the logic of which is to enable prospective students the opportunity to do smaller, more manageable, postgraduate courses in topics that will ultimately count for recognition (credit) in full master's degrees at the respective university. Offered by top-tier universities, they are more expensive than short online certificate courses, but cheaper than full master's programmes, and typically run for periods of 6 months to usually not longer than 1 year. 14

Discussion of the findings
The 4IR requires a different way of thinking and will blur the boundaries between content on its own and the application of the content where integration in an inter-and multidisciplinary setting will increasingly become the norm. South African universities incorporating subjects such as economics, politics, technology and philosophy, similar to that of top-tier international universities, are examples of this and reflect the more integrated approach to curricula attempting to upskill graduates entering the 4IR. This is particularly important amid concerns about skills constraints inhibiting economic growth in South Africa (Burger 2018 The South African universities investigated in this study acknowledge that 4IR-related content is important in commerce degrees. In most part there does not seem to be a mass overhaul of curricula, but rather that core modules tend to remain largely the same and are supplemented by additional modules addressing topics related to the 4IR. Furthermore, business schools seem to play an important role in the presentation of modules related to the 4IR. This is probably due to their role to stay current and adaptable to market trends, although the criticism is that content is not always as dynamic as it should be (Denning 2018). Needless to say, 'authentic engagement' between the relevant stakeholders to ensure meaningful curriculum changes, requires 'ongoing conversations' as the process becomes increasingly more dynamic amid the 4IR (UCT 2018b). In turn, top-tier universities offer degrees that are fundamentally multi-disciplinary and offer a wide and extensive range of modules in undergraduate programmes. Students are therefore encouraged to select from various disciplines. At postgraduate level, business schools, as opposed to discipline-specific departments, offer coursework and the range of specialised modules focusing on 4IR is extensive.
COVID-19 has set the scene to rapidly change the teaching and learning environment for South African universities. For universities to remain sustainable post-Covid-19, they have to change their business models as the traditional face-to-face mode of teaching and learning will no longer be the only feasible approach. Blended online learning approaches such as HyFlex may be considered in which students are given the option to attend classes either in person or in an online setting. By implication, besides adapting curricula to developments in the 4IR, universities need to start thinking differently about how they train students by strengthening their active learning abilities outside of the traditional face-to-face context.

Managerial implications
Six managerial implications for the management of South African universities are posited.

An online presence will become increasingly important for revenue and continuity reasons
Although face-to-face learning is the main mode of teaching at the majority of South African universities, having an online presence is becoming increasingly important, especially amid the COVID-19 pandemic. There are main drivers for the move towards a more integrated online presence in the teaching and learning environment for universities: firstly, South African universities need to become more competitive, compared to international universities, by focusing on South Africa-specific content; secondly, assuming the labour and physical resources are available, an online presence ensures an additional revenue stream in a higher education environment where the state is shifting the financial burden increasingly to students to fund their tuition (Czerniewicz, Trotter & Haupt 2019); thirdly, and arguably most importantly, an online presence will contribute to ensuring continuity in teaching and learning due to an increasingly disrupted higher education environment. The latter two reasons in particular support moving content to the virtual space as it provides some sort of continuity in the delivery of classes during times of strikes, protests and disruptions on campus such as those seen during the #FeesMustFall movement in 2015 and 2016, the unpaid National Student Financial Aid Scheme allowances in 2020, and the COVID-19 pandemic, which will continue into at least 2021 (Mafolo et al. 2020;Mbolekwa 2020;Geduld & Sathorar 2016). Given the highly politicised higher education environment in South Africa, adopting a hybrid (or blended) approach to class delivery may become the status quo in the future, despite the challenge of not all students having access to electronic devices or the internet due to coming from poor and working-class households (Brodie & Harding 2020).

The integration of science, technology, engineering and mathematics skills is integral to curriculum design
The 4IR will revolutionise the way society operates and STEM subjects will be the foundation of this. The focus on equipping future graduates with the requisite skills to meet the demands of the 4IR, must, however, not overshadow the realities facing the quality of education received by the majority of students prior to entering South African universities. The poor performance of the vast majority of South African school-leavers in STEM subjects is a concern for universities, reiterating the structural challenges in specifically the spheres of mathematics and science education. This is also exacerbated by the fact that the so-called Millennials and Generation Z require a different mindset as to how knowledge is disseminated. The use of technology in the classroom is central to this and shorter attention spans and the pervasive use of technology require educators to present classes in far more interesting and stimulating ways than in the past (Giunta 2017). Although one study suggests that the attention span for Generation Z's is 8 s (Elmore 2014), universities must adapt curricula, taking into account the changing behavioural and technological habits of students as well, yet at the same time being sensitive to the challenges many South African students have regarding access to digital devices. COVID-19 and any such disruptive event in the future, has arguably made this more relevant than ever before.

A mass overhaul of curricula is not required
Although a few specialised degrees have been established, the general trend seems to be that universities are supplementing existing degree curricula with additional modules pertinent to the 4IR. With the exception of specialised degrees, especially at top-tier universities, degrees seem to be quite 'fluid', as the focus is rather to complement core modules, related to the traditional area of specialisation, with those expected from the 4IR. This feature is considered favourable for South African universities as it 'facilitate[s] the creation of new work fields at the intersection of knowledge domains' (Bawa 2017). Universities should therefore not necessarily be lulled into a mindset that they need to 'provide everything to everyone' through a mass overhaul of curricula, but maybe consider building in more flexibility in module selection within degree programmes. Top-tier universities in particular have adopted a very explicit inter-and multidisciplinary approach to their curricula, with several South African universities having recently followed suit.
Due to the pervasiveness of online content, the reputation of universities to provide formal and reputable qualifications will be pivotal to their success Already MOOCs and platforms such as YouTube threaten the dissemination of information offered by institutions of higher learning, especially those not offering the former. By implication, if information is so pervasive and cheaper alternatives to disseminate it in the public domain potentially threaten the existence of universities, what would motivate a student to pay for a formal education at a university rather than through (1) cheaper online-based programmes from reputable top-tier universities or (2) free online content such as MOOCs? The threat this poses to universities with a dominantly face-to-face teaching and learning environment, is exacerbated as their tuition fees are higher than universities that offer an exclusively online environment. The forced sudden reaction of universities to COVID-19 has exposed this reality and threatens to result in students switching to universities which have the technological infrastructure to deal with online teaching and learning. Needless to say, the answer to the question arguably lies in the reputational benefits of qualifying from a university of repute. For a South African university, this suggests competing with the best universities in the world, and it poses a potential threat to the competitiveness of South African qualifications if these universities are able to scale their online content and offer competitive teaching to potential South African students. As the migration to a digital teaching and learning environment due to COVID-19 has shown, the challenge will be to ensure that South African students have the necessary technology and data at their disposal to facilitate online education.

Universities must require all students to take a course in ethics, specifically focusing on topics relevant to the Fourth Industrial Revolution
Top-tier universities in particular have modules focusing on the ethical dimensions of the 4IR, given that it presupposes the integration of technology in everyday human life (Schwab 2016). Although technology has resulted in huge progress made in both the medical and business environment, concerns related to, for example, cybersecurity and the confidentiality of data raise ethical concerns with regard to privacy and the intrusive nature of data management. The question therefore becomes: can a university afford to send graduates into the workplace with no exposure to what ethics are, or how to handle unethical situations and, if so, what sort of message does it send out to the business community? Although South African business schools in particular grapple with these questions (Businesstech 2017), it is not as pervasive in curricula in general. And, as indicated above, although several professional qualifications require graduates to adhere to conduct and ethical-related standards as part of either curricula of professional affiliation in the fields of commerce, there is no reason why offering a compulsory module on ethics should not be applicable to every graduate in commerce, not to mention any student studying at a university who does not specialise in one of the abovementioned career paths. Clearly, therefore, there is an acknowledgment by industry that ethics and the associated conduct in unethical situations in the workplace cannot be separated from what students need to learn at university.

Curricula must differentiate the skills of graduates to keep them competitive in the workplace
Universities need to ensure that they are driven by two overarching principles leading into the 4IR: (1) students must be provided with the requisite knowledge and skills to be part of the 4IR, and (2) the knowledge students acquire must differentiate them from the 'robots' (read: artificial intelligence, machine learning, mechanisation, automation, etc.) by focusing on their abilities to problem-solve, think critically, behave with empathy, be creative, question and dream (Marr 2018). By implication, graduates must not leave university having merely acquired the skills that technology will be able to do in the future, anyway. Given the rapid rate of change that technology brings to the fore, graduates will also need to adopt a mindset that encapsulates a lifelong learning approach. The COVID-19 pandemic has no doubt reinforced this and as long as a disrupted environment is the norm of the day, lifelong learning will be part and parcel of the mindset that the graduate of the future is expected to engender. University studies will thus be a means to an end: on-the-job experience, coupled with the skills and knowledge acquired at university, will count for more in terms of being competitive in the workplace.
Finally, although the impact on students is without question, university staff also need to be mentioned, especially while COVID-19 prevents them from attending the physical workplace. Universities must implement human resource policies that are increasingly more flexible and integrated with a performance-based culture that considers homebound work pressures. With COVID-19 likely to be part of the landscape until at least 2021, any developments in curriculum design are ultimately articulated and implemented by academic staff. Without the necessary institutional support to facilitate this, the ability of university, to capitalise on developments in the 4IR will be a futile exercise.

Conclusion
As the custodians of disseminating knowledge, universities need to be at the forefront of equipping societies for the developments leading into the 4IR. This challenge has undoubtedly been escalated to unprecedented levels due to the COVID-19 pandemic and accelerated the rate of adoption. Given the socio-economic imbalances inherent to the South African economy, failure to do this will have severe implications on the well-being of the people and exacerbate the problem from being one of being unemployed to one of becoming unemployable. If South African universities do not adapt and do so quickly, they run the risk of losing relevance in the broader higher education environment due to the competition from especially international universities which have a strong presence in the online environment. The solution is integrating the skills of the 4IR to address South Africa-specific problems and consequently not compete directly with top-tier international universities. Rather, they must become more relevant to South African problems using the tools and skills inherent to the 4IR. This will differentiate the offerings of South African universities from those of universities in the rest of the world. As such, COVID-19 has in many ways provided the platform for universities to 'reset' their business model and use technology as the fundamental tool to provide education in a time of disruption, arguably never seen before in higher education across the globe.
