Abstract
Purpose
The purpose of this paper is to report on developments and applications of mixed reality cubicles and their impacts on learning in higher education. This paper investigates and presents the cost effective application of augmented reality (AR) as a mixed reality technology via or to mobile devices such as head-mounted devices, smart phones and tablets. Discuss the development of mixed reality applications for mobile (smartphones and tablets) devices leading up to the implementation of a mixed reality cubicle for immersive three dimensional (3D) visualizations.
Design/methodology/approach
The approach adopted was to limit the considerations to the application of AR via mobile platforms including head-mounted devices with focus on smartphones and tablets, which contain basic feedback–to-user channels such as speakers and display screens. An AR visualization cubicle was jointly developed and applied by three collaborating institutions. The markers, acting as placeholders acts as identifiable reference points for objects being inserted in the mixed reality world. Hundreds of participants comprising academics and students from seven different countries took part in the studies and gave feedback on impact on their learning experience.
Findings
Results from current study show less than 30 percent had used mixed reality environments. This is lower than expected. About 70 percent of participants were first time users of mixed reality technologies. This indicates a relatively low use of mixed reality technologies in education. This is consistent with research findings reported that educational use and research on AR is still not common despite their categorization as emerging technologies with great promise for educational use.
Research limitations/implications
Current research has focused mainly on cubicles which provides immersive experience if used with head-mounted devices (goggles and smartphones), that are limited by their display/screen sizes. There are some issues with limited battery lifetime for energy to function, hence the need to use rechargeable batteries. Also, the standard dimension of cubicles does not allow for group visualizations. The current cubicle has limitations associated with complex gestures and movements involving two hands, as one hand are currently needed for holding the mobile phone.
Practical implications
The use of mixed reality cubicles would allow and enhance information visualization for big data in real time and without restrictions. There is potential to have this extended for use in exploring and studying otherwise inaccessible locations such as sea beds and underground caves. Social implications – Following on from this study further work could be done to developing and application of mixed reality cubicles that would impact businesses, health and entertainment.
Originality/value
The originality of this paper lies in the unique approach used in the study of developments and applications of mixed reality cubicles and their impacts on learning. The diverse composition in nature and location of participants drawn from many countries comprising of both tutors and students adds value to the present study. The value of this research include amongst others, the useful results obtained and scope for developments in the future.

Abstract
Purpose
This paper seeks to assess the level of impact of COVID-19 pandemic on professional practice for members of professional organisations and the general public in the conduct of business. Investigations into practice using events, attendance records and registered views are carried out. The aim is to identify the challenges and actions being taken to mitigate against them in moving from physical (face-to-face) to virtual (online) mode of operations.
Design/methodology/approach
The past two years have seen a complete change in the way we live from life at home, at work and in education. This has impacted the way professional organisations now conduct business including the need to revise ways of upskilling and sustaining practice. Core to all of this is the role of computing and communication for all persons in all works of life. The current study focusses on professional activities and support provided to members of British Computer Society (BCS), The Chartered Institute for IT. The authors examine the events provided, the conduct support provided to members and the general public. The method includes use of surveys of all stakeholders and analysis of data obtained.
Findings
The onset of COVID-19 pandemic was perceived as a real shock for everyone everywhere. Contrary to expectations, faced with the reality of having to do everyone online, the current study found that there were observed increased in the number of activities of professional organisations worldwide. Most interesting is that fact that the number of people participating in these events was found to be increasing using e-learning and other associated online tools and resources. Participants of these events were no longer restricted to local members but widespread globally. There was the appetite for more events to be put up and willingness for more individual and groups to volunteer and/or participate.
Research limitations/implications
The limitations of current study are that only a few of the many activities have been investigated in this one professional body, BCS, The Chartered Institute for IT. The fact that more events are now being carried out for the many groups and branches implies a lot more digital data would be available for further study to inform developments of members and the general public.
Practical implications
The impact of COVID-19 pandemic is a huge and evolving. It remains and presents a complicated case for the world to deal with. Amongst the many realities is that living life online has become a new normal and one everybody must learn to adjust to. Professional organisations such as the BCS would need to think of not only their members but also the general public and how well society and business can be sustained going forward. This involves considering developments of educational resources and appropriate platforms to meet the needs of the public, private and the voluntary sectors in society.
Social implications
Due to restricted physical (face-to-face) interactions, previously developed processes would require reviewing. New informed policies would need to be developed and implemented by professional organisations on revised practices resulting from impact of the pandemic. The emanating global participation from local activities presents challenges involving time, space (geographical location) and cultural differences. The digital divide that exists in society and access to the fast and reliable Internet services are also worth considering.
Originality/value
The impact of COVID-19 on professional practice applied to education and business is important in the face of the many and varied challenges everyone is facing everywhere in the world. This has been intense at home and at work globally. Although the true cause is yet to be established, it is important that ways to address challenges and continue with life are found and implemented. This paper establishes some of the impacts and present recommendations that are useful in forging ahead for people in the information technology profession.

Abstract
Purpose
The aims of this study are to examine affective responses of university students when viewing their own predictive learning analytics (PLA) dashboards, and to analyse how those responses are perceived to affect their self-regulated learning behaviour.
Design/methodology/approach
A total of 42 Northern Irish students were shown their own predicted status of academic achievement on a dashboard. A list of emotions along with definitions was provided and the respondents were instructed to verbalise them during the experience. Post-hoc walk-through conversations with participants further clarified their responses. Content analysis methods were used to categorise response patterns.
Findings
There is a significant variation in ways students respond to the predictions: they were curious and motivated, comforted and sceptical, confused and fearful and not interested and doubting the accuracy of predictions. The authors show that not all PLA-triggered affective states motivate students to act in desirable and productive ways.
Research limitations/implications
This small-scale exploratory study was conducted in one higher education institution with a relatively small sample of students in one discipline. In addition to the many different categories of students included in the study, specific efforts were made to include “at-risk” students. However, none responded. A larger sample from a multi-disciplinary background that includes those who are categorised as “at-risk” could further enhance the understanding.
Practical implications
The authors provide mixed evidence for students' openness to learn from predictive learning analytics scores. The implications of our study are not straightforward, except to proceed with caution, valuing benefits while ensuring that students' emotional well-being is protected through a mindful implementation of PLA systems.
Social implications
Understanding students' affect responses contributes to the quality of student support in higher education institutions. In the current era on online learning and increasing adaptation to living and learning online, the findings allow for the development of appropriate strategies for implementing affect-aware predictive learning analytics (PLA) systems.
Originality/value
The current study is unique in its research context, and in its examination of immediate affective states experienced by students who viewed their predicted scores, based on their own dynamic learning data, in their home institution. It brings out the complexities involved in implementing student-facing PLA dashboards in higher education institutions.

Abstract
Purpose
This paper presents a reclassification of markers for mixed reality environments that is also applicable to the use of markers in robot navigation systems and 3D modelling. In the case of Augmented Reality (AR) mixed reality environments, markers are used to integrate computer generated (virtual) objects into a predominantly real world, while in Augmented Virtuality (AV) mixed reality environments, the goal is to integrate real objects into a predominantly virtual (computer generated) world. Apart from AR/AV classifications, mixed reality environments have also been classified by reality; output technology/display devices; immersiveness as well as by visibility of markers.
Design/methodology/approach
The approach adopted consists of presenting six existing classifications of mixed reality environments and then extending them to define new categories of abstract, blended, virtual augmented, active and smart markers. This is supported with results/examples taken from the joint Mixed Augmented and Virtual Reality Laboratory (MAVRLAB) of the Ulster University, Belfast, Northern Ireland; the Abdus Salam International Centre for Theoretical Physics (ICTP), Trieste, Italy and Santasco SrL, Regio Emilia/Milan, Italy.
Findings
Existing classification of markers and mixed reality environments are mainly binary in nature and do not adequately capture the contextual relationship between markers and their use and application. The reclassification of markers into abstract, blended and virtual categories captures the context for simple use and applications while the categories of augmented, active and smart markers captures the relationship for enhanced or more complex use of markers. The new classifications are capable of improving the definitions of existing simple marker and markerless mixed reality environments as well as supporting more complex features within mixed reality environments such as co-location of objects, advanced interactivity, personalised user experience.
Research limitations/implications
It is thought that applications and devices in mixed reality environments when properly developed and deployed enhances the real environment by making invisible information visible to the user. The current work only marginally covers the use of internet of things (IoT) devices in mixed reality environments as well as potential implications for robot navigation systems and 3D modelling.
Practical implications
The use of these reclassifications enables researchers, developers and users of mixed reality environments to select and make informed decisions on best tools and environment for their respective application, while conveying information with additional clarity and accuracy. The development and application of more complex markers would contribute in no small measure to attaining greater advancements in extending current knowledge and developing applications to positively impact entertainment, business and health while minimizing costs and maximizing benefits.
Originality/value
The originality of this paper lies in the approach adopted in reclassifying markers. This is supported with results and work carried out at the MAV Reality Laboratory of Ulster University, Belfast–UK, the Abdus Salam International Centre for Theoretical Physics (ICTP), Trieste-Italy and Santasco SrL, Regio Emilia, Milan–Italy. The value of present research lies in the definitions of new categories as well as the discussions of how they improve mixed reality environments and application especially in the health and education sectors.

Abstract
Purpose
Massive open online courses (MOOCs) have received wide publicity and many institutions have invested considerable effort in developing, promoting and delivering such courses. However, there are still many unresolved questions relating to MOOCs and their effectiveness in a blended-learning context. One of the major recurring issues raised in both academic literature and in the press about MOOCs is the consistently high dropout rate of MOOC learners.
Design/methodology/approach
In this study, we applied mixed methods as an exploratory case study, which prioritised the quantitative and qualitative approaches for the data collection processes. The data were collected using a MOOC Online Self-regulated Learning Questionnaire (MOSLQ) adapted and created from an existing measuring instrument. The quantitative data was analysed using Statistical Package for the Social Sciences (SPSS Version 22) tool to conduct descriptive analysis. The qualitative results obtained from the transcribed focus group interviews in this study revealed the various behavioural patterns of how undergraduate students self-directed their learning. This focus group interview was conducted to reveal the various ways students organised and strategised their learning patterns in order to derive satisfaction in their distinctive learning behaviours and encourage motivation within their study approaches. Quantitative data collected online included a 30 items survey of which 17 respondents completed the survey items in the blended-learning study. The online course survey included 19 items of which data were gathered from 11 respondents.
Findings
Across the data, it is noticeable and clear that time management and goal setting were among the dimensions that are highly rated close to high level among SRL skills investigated in this study. We found that goal setting and task strategies predicted much better attainment of individuals controlling personal course goals, while help seeking was associated with lower goal attainment among majority of the participants.
Research limitations/implications
The study also identified several challenges. For example, there were some challenges in learners completing the survey questions even when several reminders were sent out forth nightly. At this preliminary stage, learners participated as lurkers without engaging fully with other non-academic and academic interactive activities such as surveys, in course quizzes and forums. Most of the participants in this course said they enrolled to know more about the new trend MOOC, to make friends, to have fun and so on. Although, these are some of their intentions for participating, some of the participants at some points contributed to discussion forums.
Practical implications
Our platform currently allows learners to direct their learning within the course and also allow the choice of content prerequisite in order to recommend resources necessary for their learning. This study indicates the necessity to support SRL skills and directing development of self-determination skills among the participants. This study when applied to a larger sample will demonstrate effective measurement on areas of reliability and validity as results from this small sample has indicated some high SRL skill levels for individual learners within the research.
Social implications
However, the success of any e-learning or MOOC platform should consider the following best practices and objectives: the learners' entire learning experience, the strategies used in developing the course content, the planning of the course delivery and the methods of delivery. Therefore, all e-learning platforms should be designed with a primary focus on the way students learn to improve their own learning skills and help them regulate their own independent learning habits. In another related study, the success of any e-learning course implementation should be carefully considered with regards to the course's underlying pedagogy and how learners engage with the content.
Originality/value
There are many e-learning platforms in existence globally, but little has been mentioned about the development of a MOOC platform in general that could allow independent learning and also adequately demonstrating the components and features used in these MOOC designs. This research's implication is to aid instructional designers to apply best practices in the development of an online course. The best approach in designing a good course is to consider the learners and how they could engage with the course resources independently and develop the ability to self-direct their learning. One of the main goals of e-learning platforms is primarily based on developing learning resources that would be suitable for linear course structure as directed by the course developer or instructor.

Abstract
Purpose
The purpose of this paper is to examine and discuss, in-depth, how solar electricity can be developed and used to tackle grid electricity-related problems in African countries suffering from unreliable and inadequate grid electricity.
Design/methodology/approach
The paper discusses in depth the current status of grid electricity in Africa continent and suggested solar electricity as an alternative cost-effective method to the existing grid electricity problem in remote areas. An extensive analysis of the major contribution of solar electricity in various sectors such as economic, health, communication, social and environmental benefits is provided. The paper concludes with a discussion on how solar power generation can be developed.
Findings
The paper shows that in developed countries where ICT has been applied extensively, ICT offers increased opportunities for sustainable economic development and plays a critical role in rapid economic growth, productive capacity improvements, education, government, agriculture and international competitiveness enhancement. The paper has pointed out that ICT has yet to make significant impact in most African countries due to lack of reliable and adequate electricity. Solar electricity has been seen as the most cost-effective way of generating electricity, especially in remote rural areas, for ICT devices. For the widespread of solar power generation in Africa, various strategies have been identified which include training of qualified solar engineers and technicians, establishing PV markets and business modes, introduction of solar energy education in schools and universities, political leaders appreciating solar electricity as one of the major energy component, lowering initial cost of the PV technology, availability of finance mechanisms for rural communities, import tax exemption and African countries regarding rural electricity as one of the basic needs.
Practical implications
The paper shows that the problems of lack of qualified solar technicians and established PV markets and business modes (especially in remote areas), lack of solar energy education in schools have to be addressed before the benefits of ICT in Africa can be seen. Other issues include African countries appreciating solar electricity as one of the major energy component, lowering initial cost of the PV technology, availability of finance mechanisms for customers, import tax exemption and African countries regarding rural electricity as one of the basic needs like food, shelter and clothing. Overhaul of existing systems needs to take place in order to provide the means to deal with some of these issues.
Originality/value
Availability of reliable electrical energy remains crucial for development of ICT in rural African countries. Solar electricity is clearly one of the most promising prospects to the grid electricity problem in African countries because most African countries lie in the sunshine belt. The paper raises awareness about this in a unique way and suggests some novel measures about increasing the availability of solar systems for solar power generation. It is anticipated that the increases in solar power generation, especially in remote areas, will increase the use and application of ICT in various sectors.

Abstract
Purpose
The purpose of this paper is to systematically examine and draw attention to the potential benefits of solar power generation for access to and use of information and communication technologies (ICT) aimed at sustainable development in emerging economies.
Design/methodology/approach
Electricity plays a crucial role in the development and use of ICT and in the process of striving to achieve sustainable development in emerging economies. It has been shown that electrical energy is intrinsically linked to economic, environmental and social dimensions of sustainable development. An extensive analysis of the major contribution of solar electricity in various sectors such as economic, social and environmental benefits is provided. The paper concludes with a discussion on current status of solar electricity in major emerging economies, their planning policies and strategies for promoting solar power generation for increased access to ICT by people and sustainable development of society.
Findings
The demand for electricity in residential, commercial and industrial sectors in developing countries (emerging economies) is likely to increase, both as a result of increase in population and expanding industrialization. It remains amongst others, a growing challenge for these nations to obtain and put in place reliable and secured electricity supplies, for accessing ICT and to work towards achieving sustainability. The important issues that must be considered and addressed for the successful implementation of solar electricity programs for sustainability and wellbeing in developing nations are pointed out.Practical implications – The paper shows that the problems of lack of qualified solar technicians and established Photovoltaic (PV) markets and business modes, renewable (solar) energy education have to be addressed. Other issues include appreciation of solar electricity as one of the major energy component, lowering initial cost of the PV technology, availability of finance mechanisms for customers, import tax exemption and regarding electricity as one of the basic needs like food, shelter and clothing. Overhaul of existing systems needs to take place in order to provide the means to deal with some of these issues.
Originality/value
Availability of power remains crucial for development in emerging markets. Solar electricity is of major interest for the energy sector in developing or emerging economies because it offers the possibility of generating renewable electricity using sunlight – a resource that is widely and freely available in most, if not all, developing countries. This paper raises awareness about this in a unique way and identifies problems faced by the sectors. To address some of these challenges without compromising the goal of sustainability and development, it is important that low carbon emitting electrical energy sources such as solar electricity are given high priorities by policy makers, industries and research and development institutions in emerging countries. Some innovative suggestions are provided for achieving this.

This paper aims to report on the design and implementation of an e‐laboratory for enhanced science, technology and engineering education studies.
Abstract
Purpose
This paper aims to report on the design and implementation of an e‐laboratory for enhanced science, technology and engineering education studies.
Design/methodology/approach
The paper assesses a computer‐based e‐laboratory, designed for new entrants to science, technology and engineering programmes of study in further and higher education to enable them complete proper “hands‐on” (not simulation) laboratory experiments off‐campus and also in virtual learning environments accessible remotely. The development of such a laboratory was in response to the inherent inability of web‐based learning environments to duplicate, off‐campus, the laboratory facilities and availability on‐campus. The measurement of effectiveness relates to whether a laboratory task can be accurately and completely achieved. Common parameters included percentage task completion, error rate and assistance required. Operations under different conditions were studied and observations made from comparison on implementations.
Findings
E‐laboratories were found to be more student‐centred with learners taking responsibility for their own learning.. The face‐to‐face pre‐computer scenario learners had a very low completion rate, a high error rate and required constant assistance. The computer‐based scenario resulted in a high completion rate, low error rate and a significant reduction in learner supervision.
Research limitations/implications
The technical constraints imposed by present online environments, the resulting impact on specific learning styles, and possible solutions to overcome these limitations are discussed.
Practical implications
Both quantitative surveys and qualitative interviews established a positive impact on student learning, thus justifying development of similar systems. More research and applications could follow as this has the potential to impact positively on development and use of e‐labs for enhanced science, technology and engineering studies in terms of costs, time and space requirements.
Originality/value
The recent interest and advances in the development of remote and virtual labs has shown that students of today, who are digital natives, especially those in the fields of science, technology and engineering, find the use of e‐laboratories very useful in enhancing their studies, encouraging them to use familiar technologies to access and do experiments either remotely or virtually online, thereby enhancing their learning. The approach adopted is unique and original, blending both virtual and hands‐on approach to experimental studies.

Abstract
Purpose
The purpose of this paper is to present principles from the complex approach in education and describe some practical pedagogic experiences enhancing how “real world” perspectives have influenced and contributed to curriculum development.
Design/methodology/approach
Necessity of integration in terms of knowledge modeling is an historical trend in Engineering and Computer Sciences curricula. Integration of particular technical aspects with wide global aspects is a response to globalization demands. Globalization demands require new approaches, at both educational and teaching levels. Also, educational level embeds a wide range of pedagogical proposals or teaching proposals. Since the 1990s, Engineering and Computer Sciences curricula have emphasized, increasingly, the project‐oriented approach in the Engineering field of knowledge and software engineering contents has migrated to beginners or fresh‐man level in Computer Sciences courses. This approach is called the Complex Approach in education. COOL – “Comprehensive Object‐Oriented Learning” – is an educational project mentored by Emeritus Professor Kristen Nygaard, from the Department of Informatics at Oslo University, which deals with the complex approach in education. Professor Nygaard passed away in 2002. This project was published in 2006 under the title of “Comprehensive Object‐Oriented Learning: the Learner’s Perspective”. This paper analyses theoretical aspects in Nygaard's project and also compares aspects with the author's work teaching Object Oriented Modeling in Computer Sciences and Engineering, at Federal University of Santa Catarina – UFSC, Florianopolis, Brazil. The author's pedagogic proposal, developed on those contexts, since 1997, is supported by Nygaard theory and also by Edgar Morin “Complex Thought” theory adopted by UNESCO, titled Complex Thought cathedra.
Findings
Innovation, in terms of Engineering and Computer Sciences curriculum development, is deeply related to the complex approach educational paradigm. Consequently, innovation in terms of pedagogic practices is also deeply related to the complex approach perspective. Complex approach overpasses fragmented view of knowledge towards integrative view concerning curriculum development in technological areas.
Research limitations/implications
The comprehensive object‐oriented learning presented here is applied to Computer Science and Engineering. However its development and application could impact other disciplines and education, especially in relation to technology integration in education.
Originality/value
The paper presents and discusses COOL as a concept and approach for enhanced learning, in a novel manner, taking account of theoretical underpinnings developed aligned to modern thinking.
