The fourth industrial revolution: the implications of technological disruption for Australian VET

Much discussion has occurred about the impact that technological disruption will have on the Australian workforce. A recent paper by the National Centre for Vocational Education Research (NCVER), Skilling for tomorrow (Payton 2017), examines the various ways by which the growth in technological advance is reshaping the labour market, workforce and jobs. Despite uncertainty about the scale and nature of the effect, there is a growing consensus that Australia’s tertiary education system needs to change to meet the requirements of a future labour force focused on innovation and creativity. This research examines the relationship between emerging ─ or disruptive ─ technologies and the skills required, with a focus on the anticipated necessary skills from the perspective of both the innovators (technology producers) and industry (technology users). In this research the term ‘disruptive technologies’ refers to large-scale technology/market changes occurring through technological advances such as automation, advanced robotics and virtualisation

Towards Modern, Accessible and Dynamic HPC Using Container-based Virtual Clusters

In this thesis, a novel Virtual Container Cluster (VCC) framework is presented. Despite the growing popularity of container virtualisation in order to increase the flexi-bility of the software stack, run time environment virtualisation still poses significant portability challenges; by depending on the underlying cluster execution paradigm,a niche class of HPC only containers has emerged. This trend is detrimental to reusability, reproducibility, and encouraging new communities to HPC. Traditional virtualisation techniques have a rich history within HPC, and have been demonstrated to offer much more than software flexibility. A Virtual Machine by nature requires an OS and full stack environment akin to a physical machine, and this allows it to be instantiated regardless of the underlying machine and what services it provides. This capability is essential in order to implement job forwarding and spanning - where the burden of an entire job can be transferred or shared between hetero-geneous cluster systems - with a high level of confidence that the environments will be compatible. In turn, this brings improvements to global resource performance, reducing the job turnaround time and increasing cluster utilization. The VCC is an innovative solution that combines the full stack and container virtualisation approaches. Therefore, it offers both the flexibility of containers with the improved portability, performance and scalability of the full stack approach. In order to maintain the same accessibility and lower barrier of entry as the run time environment approach, the design incorporates an autonomous configuration and contextualisation mechanism, along with a Software Defined Networking technology, to ensure the full stack container does not place an additional burden on the user. The usefulness and performance is validated through benchmarking and two case studies: virtual clusters in the classroom and inter-institutional spanning

Factors impeding the usage of elearning at a telecommunication organization in South Africa: bridging the gap with cloud services

With the enormous competition in the industry, organizations must frequently find better ways to embrace organizational learning. This research study advocates eLearning to be one of the best methods for organizational learning, and this is the study’s main area of interest. This research explored a case at a telecommunication organization named ComTek (pseudonym). The research study addressed a problem of eLearning low usage rate, which resulted in ComTek not meeting their set learning targets during the time of the study. The usage rate was measured using the number of enrolled assessments. The study uses qualitative methods to propose a conceptual framework to understand the causes of low eLearning usage. This conceptual framework illustrated the use of the activity theory elements to understand the problem of eLearning low usage, paired with the use of cloud computing services to access eLearning, and the use of content delivery techniques to help understand eLearning low usage. This conceptual framework took advantage of cloud services like Software as a Service (SaaS), Platform as a Service (PaaS), and Infrastructure as a Service (IaaS). This research study focused on the periods from 2016 to 2017 for collecting data and creating an understanding of the research setting, while other data was derived from historical documents about the phenomenon studied. During this period, there was inadequate literature about cloud computing and other aspects to consider within the domain of telecommunication organizations. The literature study, therefore, comprised of literature from different domains. During the study, ComTek used eLearning with the aid of learning management systems (LMS) to manage learning and leverage employee skills. During the period of the study compared to other years, about 50% of assessments had a usage rate of below 80%, a standard target established by ComTek as a benchmark, placing compliance and training at a low rate. Of the 50% of assessments, some were just above 40% in usage rate, were of a high stake, and were in the categories of compliance and training iv assessments. While this was the case, this study did not consider the technical implementation of the application systems involved, and did not create any form of intervention, but focused on understanding the activities that were involved in the learning environment. This research study used a paradigm that was constructive and interpretive in nature, using qualitative methods with the belief that there were multiple realities in understanding the situation at ComTek and possible solutions to it. To unpack the multiple realities, an exploratory case study was conducted as a research approach. In this study, the researcher used multiple data collection methods, including open-ended questionnaires and unstructured interviews.School of Computin

An investigation into decision making within secondary schools on information and communications technology inside the same Northern county of England

In 1997, New Labour introduced a national ICT strategy for schools and went on to spend over £3.54 billion on educational technology. This exploratory study examines whether changes to government funding for educational technology has altered the view of the role of ICT in the thinking of senior leaders. It contrasts views of the role of ICT in the classroom from those in the ‘Edutopian’ school (Chen and Armstrong, 2002) who see it as transformational, innovative and an essential part of preparing children for modern life, with those who adopt a more cautious ‘Dystopian’ narrative as found across the work of a range of academics, such as, Cuban (2001), Selwyn (1999, 2002, 2004, 2008, 2011, 2014) and Facer (2011). This exploratory study draws on a small sample of interviews with key decision makers based in different schools that are all located within a single county in the North of England. The findings suggest that ICT remains one of the top five spending priorities for schools who explain this with the use of the Edutopian globalisation and economic arguments. In the study, a minority of key decision makers for ICT had formal training and this was reflected in the range of processes and procedures they adopted. The movement by government away from a centralised planning approach was welcomed across the sample and the loss of some ring-fenced funds was deemed by the ‘rural schools’ to have improved outcomes and created solutions more attuned to local requirements. Edutopian arguments were used by all participants to explain their planning and vision for the future with some desiring to move to ubiquitous or 1:1 tablet teaching solutions

Student perceptions on skills and learning challenges in the use of educational technology in a low-contact, blended and professional learning context: a grounded theory of ‘improvised learning’

This research project provides an original contribution to knowledge, comprising a grounded and unified theory of improvisational behaviours via Blended Learning and suggests a new paradigm of self-regulated, improvisational learning for potential application beyond the field of study. The study comprises an original Grounded Theory of ‘Improvised Learning’ demonstrating the most prevalent challenges, strategies and behaviours of students undertaking Higher Education programmes in a campus-based, low-contact teaching environment. The participant group were typically undertaking accredited professional programmes (usually related to a profession such as nursing or accounting). The students engaged in ‘Blended Learning’ i.e. study on-campus alongside use of learning technologies such as a Virtual Learning Environment (VLE). The research project used Grounded Theory as an holistic methodology to investigate the experience of students in this study context. The main data collection phase consisted of informal individual or group discussions held in classes, open plan Library areas or IT Labs. Grounded Theory is a sociological methodology designed to formulate a new (Grounded) theory from a ‘substantive area’, i.e. a participant group typically comprising a shared vocational role or activity. Key elements of Grounded Theory include an emphasis on induction-based conceptualisation of theory from descriptive participant indicators and the continuous comparison of data for the emergence of ‘theoretical categories’ or codes. The ultimate aim of Grounded Theory is to demonstrate how conceptual categories inter-relate within a common theoretical explanation for the behaviour of participants (the ‘core category’). This grounded study of professional learners identified a number of theoretical models of behaviour for engaging with Blended Learning, including innovative self-led use of Information Technology and collaborative learning. The emergent ‘core category’ - reflecting all dependant codes or variables was defined as ‘Improvised Learning’, explaining conceptually how students employ self-led strategies and skills to engage with disparate systems, environments and resources

An investigation into internetworking education

Computer network technology and the Internet grew rapidly in recent years. Their growth created a large demand from industry for the development of IT and internetworking professionals. These professionals need to be equipped with both technical hands-on skills and non-technical or soft skills. In order to supply new professionals to the industry, educational institutions need to address these skills training in their curricula. Technical hands-on skills in internetworking education can be emphasised through the practical use of equipment in classrooms. The provision of the networking equipment to the internetworking students is a challenge. Particularly, university students in developing countries may find that this equipment is ineffectively provided by their teaching institutions, because of the expense. Modern online learning tools, such as remote access laboratories, may be used to address this need. However, the provision of such tools will also need to concentrate upon the pedagogical values. In addition, traditional remote access laboratories provide only text-based access, which was originally designed for highly professional use. Novice students may struggle with learning in these virtual environments, especially when the physical equipment is not available locally. Furthermore, non-technical skills or soft skills are social skills that should not be neglected in graduates’ future workplaces. A traditional model of developing soft skills that was used in face-to-face classroom may not be as effective when applied in an online classroom. Research on students’ opinions about their soft skills development during attending internetworking courses is needed to be conducted. In order to address both research needs, this study was focused on two research aspects related to online learning in internetworking education. The first focus was on research into providing a suitable technical learning environment to distance internetworking students. The second focus was on the students’ opinions about their non-technical skills development. To provide a close equivalent of a face-to-face internetworking learning environment to remote students in Thailand, a transformation of a local internetworking laboratory was conducted. A new multimedia online learning environment integrated pedagogically-rich tools such as state model diagrams (SMDs), a real-time video streaming of equipment and a voice communication tool. Mixed research data were gathered from remote online and local student participants. The remote online participants were invited to use the new learning environment developed in this study. Qualitative research data were collected from twelve remote online students after their trial usage. Concurrently, another set of research data were collected from local students asking their opinion about the development of soft skills in the internetworking course. There were sixty six participants in this second set of research data. Although the research data was limited, restricting the researcher’s ability to generalise, it can be concluded that the provision of multimedia tools in an online internetworking learning environment was beneficial to distant students. The superiority of the traditional physical internetworking laboratory cannot be overlooked; however, the remote laboratory could be used as a supplementary self-practice tool. A concrete learning element such as a real-time video stream and diagrams simplified students learning processes in the virtual environment. Faster communication with the remote instructors and the equipment are also critical factors for a remote access network to be successful. However, unlike the face-to-face laboratory, the future challenge of the online laboratory will creating materials which will encourage students to build soft skills in their laboratory sessions
