The increasing adoption of remote laboratories in education along with the shift from eLearning 2.0 towards eLearning 3.0, have demanded several considerations in their implementation and delivery format. In response to these needs, this contribution introduces a novel model, Laboratory as a Service (LaaS), for developing remote laboratories as independent component modules and implementing them as a set of loosely-coupled services to be consumed with a high level of abstraction and virtualization. LaaS aims to tackle the common concurrent challenges in remote laboratories developing and implementation such as inter-institutional sharing, interoperability with other heterogeneous systems, coupling with heterogeneous services and learning objects, difficulty of developing, and standardization. Beyond the academic context, LaaS will facilitate the incorporation of remote laboratories in the ecosystem of the ubiquitous smart things surrounding us, which increases everyday with the approaching Web of Things (WoT) and artificial intelligence era. This, in turn, will create a breeding ground for online control, experimentation, and discovery—in either formal or informal context and with neither temporal nor geographical constraints.

Abstract-It is of crucial importance the integration of practical sessions in engineering curricula owing to their significant role in understanding engineering concepts and scientific phenomena. However, the lack of practical sessions due to the high costs of the equipment and the unavailability of instructors has caused a significant declination in experimentation in engineering education. Remote laboratories have tackled this issues providing online reusable and shared workbenches unconstrained by neither geographical nor time considerations. Thereby, they have extremely proliferated among universities and integrated into engineering curricula over the last decade. This contribution compiles diverse experiences based on the deployment of the remote laboratory, Virtual Instrument Systems in Reality (VISIR), on the practices of undergraduate engineering grades at various universities within the VISIR community. It aims to show the impact of its usage on engineering education concerning the assessments of students and teachers as well. In addition, the paper address the next challenges and future works carried out at several universities within the VISIR community.

There is no doubt that the implementation of practical sessions in engineering education paves the way for students to be familiar with the instruments and thus, with the industrial realworld. Moreover, they augment the learning outcomes by strengthening the understanding of scientific concepts and theories. Unfortunately, there exist a wide gap between the engineering educational curricula and the industrial real-world owing to the lack of experimentation availability. This is due to high cost and administration burdens that have hindered the adoption of practical sessions causing a significant decline in experimentation within engineering education. Recently, with the advent and exploitation of computer and communication technologies, remote laboratories have broadly proliferated among many universities. Remote laboratories provide on-line ubiquitous workbenches unconstrained by neither temporal nor geographical considerations and allow an interactive learning environment that maintains student attention. In this context, hundreds of remote laboratories for industrial electronics applications have been developed and numerous technologies have emerged in order to facilitate their construction and implementation. This paper reports on state-of-art remote laboratories for industrial electronics applications. and their design stages. The paper addresses many solutions in the development and the design stages, along with cutting edge technologies involved. This is in order to foster remote laboratories adoption within industrial electronics disciplines and hence, increase the industrial competencies in engineering education.
