Evaluating the impact of the augmented reality learning environment on electronics laboratory skills of engineering students

Abstract

In engineering education, laboratory experience is powerful in building up the specialized aptitudes and skills of the engineering graduates by structuring and conducting practical experiments. In engineering laboratories, the student often deals with complex laboratory equipment to perform the experiment. Oscilloscope and function generator are frequently used electronic equipment in electronics engineering laboratories. Augmented reality (AR) technology has the capacity to provide a unique learning experience to the students which can ease down the difficulties faced by students while operating laboratory equipment. In this paper, an augmented reality learning environment (ARLE) is developed which could help the student in operating the laboratory equipment. The study aims to determine the impact of AR intervention on student laboratory skills, cognitive load, and learning motivation. The experiment was conducted amongst 60 first‐year undergraduate engineering students. The participants were randomly divided into two groups: Experimental group and Control group. The participants of the experimental group were given ARLE treatment while the participants from the control group were given traditional teaching treatment. The experimental results suggest that AR intervention has a significant positive impact on student laboratory skills. Also, ARLE is an effective tool in reducing the cognitive load of students while operating laboratory equipment. The student feedback indicates that the students of the experimental group operated the equipment without any fear of damaging the equipment as they were already familiarized with the equipment in ARLE. The results of this study recommend AR as an adequate technology for developing unique AR experiences for engineering education.

A framework utilizing augmented reality to improve critical thinking ability and learning gain of the students in Physics

“…From recent studies, it has been observed that 3D animated content provides a more immersive experience to the learners. Also with the current change in the pedagogical style of engineering education, learning through games, digital platforms, and modern techniques is more beneficial to the students as it raises students' attention and enthusiasm during the learning activity [32,35]. Augmented reality (AR) has the capability to provide an engaging and interactive learning experience to the students.…”

Case Study: Student's Response Towards Online Learning in Engineering Education During COVID-19 Pandemic

“…One of the engineering innovations developed in AR/VR laboratory of Chitkara University, Punjab, India is AR learning system in which students can work with the virtual replicas of two laboratory equipments that are function generator and oscilloscope. These two equipments are essential for electronics students to observe/display the variation of voltage/current waveforms with respect to time on a two-dimensional plot (Singh et al, 2019). Students can generate different waveforms such as sinusoidal wave, square wave, or triangular wave.…”

Augmented and virtual reality for physics: Experience of Kazakhstan secondary educational institutions

“…Due to the interesting visualization, interactivity, and game forms of programs based on it, this technology can be used in the development of teaching materials at all levels of education, from preschool to universities. AR allows you to support lectures, seminars, and training with visual materials, show students all aspects of a real object or process being studied, which in general has an enormous effect, improving the quality and pace of educational processes and reducing their cost [8,54].…”

“…They allow revealing the students' interest in the subject, stimulate positive emotions, accelerate the process of learning, and help to understand the material better. AR and VR bring the element of a game into the learning process, which certainly positively affects the learners' performance and increase their motivation and confidence [8,11,16,38,54].…”
