Abstract
Digital twin (DT) is an emerging technology that enables sophisticated interaction between physical objects and their virtual replicas. Although DT has recently gained significant attraction in both industry and academia, there is no systematic understanding of DT from its development history to its different concepts and applications in disparate disciplines. The majority of DT literature focuses on the conceptual development of DT frameworks for a specific implementation area. Hence, this paper provides a state-of-the-art review of DT history, different definitions and models, and six types of key enabling technologies. The review also provides a comprehensive survey of DT applications from two perspectives: (1) applications in four product-lifecycle phases, i.e. product design, manufacturing, operation and maintenance, and recycling and (2) applications in four categorized engineering fields, including aerospace engineering, tunneling and underground engineering, wind engineering and Internet of things (IoT) applications. DT frameworks, characteristic components, key technologies and specific applications are extracted for each DT category in this paper. A comprehensive survey of the DT references reveals the following findings: (1) The majority of existing DT models only involve one-way data transfer from physical entities to virtual models and (2) There is a lack of consideration of the environmental coupling, which results in the inaccurate representation of the virtual components in existing DT models. Thus, this paper highlights the role of environmental factor in DT enabling technologies and in categorized engineering applications. In addition, the review discusses the key challenges and provides future work for constructing DTs of complex engineering systems.

Abstract
Purpose
Upon graduating from university, many engineers will work in new product development and/or technology adoption for continuous improvement and production optimization. These jobs require employees to be cognizant of ethical practices and implications for design. However, little engineering coursework, outside the traditional ABET (Accreditation Board for Engineering and Technology) required Engineering Ethics course, accounts for the role of ethics within this process. Because of this, engineering students have few learning opportunities to practice and reflect on ethical decision-making.
Design/methodology/approach
This paper highlights one approach to integrating ethics into an engineering course (outside of engineering ethics). Specifically, the study is implemented within a five-week module with a focus on big data ethics, as part of a Supply Chain Management Technology course (required for Industrial Engineering Technology majors), using metacognition as the core assessment.
Findings
Four main themes were identified through the qualitative data analysis of the metacognitive reflections: (1) overreliance on content knowledge, (2) time management skills, (3) career connections and (4) knowledge extensions.
Originality/value
Three notable points emerged which contribute to the literature. First, this study showcased one example of how an ethics module can be integrated into an engineering course (other than Engineering Ethics). Second, this study demonstrated how metacognitive reflections can be used to reinforce student self-awareness of the learning process and connections to big data ethics in the workplace. Finally, this study exhibited how metacognitive reflection assignments can be deployed as a teaching and learning assessment tool, providing an opportunity for the instructor to make immediate changes as needed.

Abstract
Although general courses related to humanities, social sciences, education and pure sciences are popularly taught through distance mode, through the institutions involved in teaching distance mode techniques for some time, more practical application courses such as engineering technology and applied sciences are less popular as distance mode teaching till recent. The current technical advancement is making it possible for more practical application courses to be offered through distance education techniques. The Faculty of Engineering Technology of the Open University of Sri Lanka is one of the few faculties involved in teaching of engineering technology through distance mode in the region. Faculty offers courses leading to diploma in technology, bachelor in engineering technology, postgraduate diplomas and postgraduate degrees in engineering through distance mode. The diplomats and graduates passing out from the faculty have to compete with the diplomats and graduates passing out from the conventional universities in the common job markets. Hence to maintain a high quality of the diploma/degree is important. Attempt is made to develop a quality assurance system that will help to maintain a high standard of the faculty diploma/graduate output. This study investigates the strengths, and in particular the weaknesses of quality assessment practices used in conducting subject reviews in Sri Lankan universities, especially when it comes to subject reviews in relation to more practical application courses such as engineering technology and applied sciences. This paper describes the aspects that were looked into: adopted current practices & the weaknesses, areas identified to check on quality maintenance, and measures to be taken to improve in developing a quality assurance mechanism based on the Faculty of Engineering Technology at Open University of Sri Lanka.

Abstract
Purpose
At present, humankind is facing rapid and profound changes in society, science, technology, economy and environment. The 21st century has witnessed extraordinary scientific and technological progressions. Improvement of technology has generated new educational technique known as e-learning. Nowadays, popularity of e-learning is growing rapidly and numerous educational organizations, public, academic and digital libraries are embracing it. Lately, engineering education is heading toward the blended education system as it successfully combines both chalk and talk system (face-to-face), computer-assisted learning methodologies and internet access feature to learners.
Design/methodology/approach
This work discusses the potential of e-learning as an educational system for engineering topics and the challenges faced by educational organizations and public libraries as their partners in applying this system for engineering topics. In addition, number of national and international successful engineering e-learning trials that have been created, organized and/or hosted by educational organizations and public libraries are presented.
Findings
The author presents challenges and obstacles that stakeholders, teachers, professors and librarians should be aware of to develop and support the e-learning system. Hence, a number of recommendations are provided to build a bridge linking e-learning and engineering education.
Originality/value
This paper is a complementary work to a previously published study. In this paper, the author sheds light on the link between the e-learning system and the engineering education provided by the educational organizations and hosted by public libraries.

Abstract
Purpose
Photogrammetry enables scientists and engineers to make accurate and precise measurements from optical images and other patterns of reflected electromagnetic energy. Photogrammetry is taught in surveying, geomatics and similar academic programs. For a long time, it has been observed that there is a lack of diversity and underrepresentation of different groups in the surveying and geomatics workforces for various reasons. Diversity fosters more innovative environments, helps employees be more engaged and boosts productivity rates. Although efforts are being made to solve this problem, most attempts did not significantly improve the diversity issues in this field. To address this problem, we designed a new curriculum for a photogrammetry course, which integrates entrepreneurial mindset (EM), bio-inspired design and Science, Technology, Engineering, Arts and Mathematics (STEAM) into the photogrammetry course for this study.
Design/methodology/approach
In this study, the participatory action research method, Photovoice, was used to gather data. Students were asked to respond to photovoice and metacognitive reflection prompts to understand student perceptions about the importance of Unmanned Aerial Vehicles (UAVs) in photogrammetric mapping. Students were required to respond to each prompt with three pictures and a narrative. These reflections were analyzed using thematic analysis.
Findings
The analysis of the photovoice and metacognitive reflections resulted in six themes: promoting digital literacy, promoting job readiness and awareness, improving perceived learning outcomes, increasing interest in pursuing careers in surveying/geomatics, encouraging learner engagement and increasing awareness of the role of art in map making.
Originality/value
This is the first study conducted at our Hispanic Serving Institution, which specifically designed a curriculum integrating EM, bio-inspired design and STEAM concepts to address diversity issues in surveying and geomatics engineering disciplines.

Abstract
Purpose
The information technology (IT) sector has been seen as central to society's transformation to a more just and sustainable society, which underlines teachers’ responsibility to foster engineers who can contribute specifically to such ends. This study aims to report an effort to significantly update an existing engineering programme in IT with this ambition and to analyse the effects and challenges associated with the transformation.
Design/methodology/approach
This study is based on a combination of action-oriented research based on implementing key changes to the curriculum; empirical investigations including surveys and interviews with students and teachers, and analysis of these; and a science and technology studies-inspired analysis.
Findings
Respondents were generally positive towards adding topics relating to sustainability. However, in the unmaking of traditional engineering subjects, changes created a conflict between core versus soft subjects in which the core subjects tended to gain the upper hand. This conflict can be turned into productive discussions by focusing on what kinds of engineers the authors’ educate and how students can be introduced to societal problems as an integrated part of their education.
Practical implications
This study can be helpful for educators in the engineering domain to support them in their efforts to transition from a (narrow) focus on traditional disciplines to one where the bettering of society is at the core.
Originality/value
This study provides a novel approach to the transformation of engineering education through a theoretical analysis seldom used in studies of higher education on a novel case study.

Abstract
Strategies for teaching engineering in the United Arab Emirates (UAE) have been evolving over the past decades due to innovations in technology, as well as the development of educational methodologies. In the recent past, the focus for engineering faculty has been not only on promoting the skills needed to raise the level of employability of Emirati graduates, but increasingly on new educational methodologies, e-learning and wireless networked laptop technology. Students in the UAE exhibit certain characteristics emerging from a variety of cultural and historical traditions, as well as from methodologies of education used at the pre-tertiary levels. These characteristics include expecting to be passive recipients of taught information, and lack of independence in their approach to problem solving. In this paper I discuss the development of strategies to facilitate the transition of students from passive to active learning; examine the role of technology-driven educational methodologies in promoting independent and group-centered learning skills; and use a case study to explore the instruction of Engineering Design and Computer-Aided Design (CAD) and to examine how classroom management techniques have changed as a result of the growing use of technology.
