“…In engineering institutes, the student has limited access to the laboratory equipment due to a busy academic schedule of the laboratory facility. The cost of purchasing and maintaining the complex laboratory hardware is one of the factors, which limits the students from working on the laboratory hardware [5,8]. Virtual and web‐based laboratories can engage the students and give a similar experience about the laboratory facility [10,24].…”

Engineering laboratory courses have a significant role in building practical knowledge and enhancing the skills of the students. While working in electronics laboratories, students often operate complicated laboratory equipment and juggle through a set of multiple knobs and buttons to configure the equipment(s). It takes a lot of practice to master the skill of operating the laboratory equipment and it becomes difficult for students to operate the equipment without any prior experience. Virtual reality (VR) is the emerging technology and has the potential to provide a better learning experience to the students. In this paper, a VR‐based learning environment (VLE) is developed, which aims to give prior training to the engineering students about the electronics laboratory hardware. An experimental study was conducted to measure the effectiveness of VR on student knowledge development, learning motivation, and cognition. The study was conducted among the 65 engineering students and they were randomly divided into two groups: treatment group (N = 33) and control group (N = 32). The students of the treatment group were taught with the VR approach and students of the control group were taught with a conventional teaching approach. The outcomes of the experiment indicate that VR has a significant positive impact on student knowledge, learning motivation, and cognition. By interacting with the three‐dimensional virtual models of the laboratory instruments, students were able to demonstrate an improved understanding of the laboratory hardware. Also, the treatment group students mentioned that they were not worried about the equipment malfunction that has further enhanced their confidence and reduced the cognitive load.

“…The main goal of this work is to propose a new mixed hardware-software architecture, based upon existing ones (e.g., [22]), which aims to promote the development of practical laboratories that are suitable for the aforementioned realworld usage. The architecture should serve as a basis for the development of multi-instance remote laboratories, especially those focused on microcontroller-based systems experimentation and embedded systems experimentation.…”

Online remote laboratories are a particularly promising tool for effective STEM education. They offer online universal access to different hardware devices in which students can experiment and can test and improve their knowledge. However, most of them have two significant limitations. First, given that most of them are developed as, or evolve from single-user proofs of concept, they have no scalability provisions other than full laboratory replication. And second, when this is done, cost efficiency is often neglected. This paper presents the requirements for the creation of a novel remote laboratory architecture focused on, but not limited to, embedded systems experimentation. An architecture, based on Redis (an open source, in-memory data structure store, which is often used as database, cache or message broker), a modular design, and hardware-sharing techniques, is proposed in order to achieve the combined requirements of high scalability and cost efficiency. This mixed hardware-software architecture serves as a basis for the development of remote laboratories, especially those focused on microcontroller-based systems experimentation and embedded devices experimentation. From a user perspective the architecture is webbased, and has provisions to be easily adaptable to different Learning Management Systems and different hardware embedded devices. A new microcontroller-oriented remote laboratory based on the architecture has been developed, with the aim of providing valid evaluation data, and has been used in a real environment. The architecture and the resulting remote laboratory have been compared with other state of the art remote laboratories and their architectures. Results suggest that the proposed architecture does indeed meet the main requirements, which are scalability through replicability and cost efficiency. Furthermore, similarly to previous architectures, it promotes usability, universal access, modularity and reliability.
