Investigating the Effectiveness of Desktop Virtual Reality for Teaching and Learning of Electrical/Electronics Technology in Universities

Abstract

This study compared efficiency of desktop virtual reality with a conventional classroom learning practice for the teaching and learning of electrical/electronics technology. This was measured through academic achievement, learning interest, and engagement. A quasi-experimental design was employed for this study. Four universities were used for the study. The students were within the ages of 17 to 24?years. Students were assigned to either an experimental or comparison group based on intact classes. A total of 149 students participated in this experiment; however, only 142 samples could be analyzed. Seven samples were not analyzed due to incomplete instruments answered and absenteeism. Seventy-four students were in the virtual reality group while 68 students were in the non virtual reality group. The sample was 78.52% and 21.48% in males and females, respectively. Analysis of covariance was used to test three formulated hypotheses on effects of desktop virtual reality on the learning effectiveness of the students. There was a significant difference in academic achievement, learning interest, and learning engagement between the two groups. It was established that desktop virtual reality positively affected students’ academic achievement, learning interest, and engagement of students in electronics technology. It was suggested that virtual reality should be adopted to augment laboratory practices for the teaching and learning of electrical/electronics technology in Nigerian universities.

Immersive Anatomy Atlas: Learning Factual Medical Knowledge in a Virtual Reality Environment

In order to improve learning efficiency and memory retention in medical teaching, furthering active learning seems to be an effective alternative to classical teaching. One option to make active exploration of the subject matter possible is the use of virtual reality (VR) technology. The authors developed an immersive anatomy atlas which allows users to explore human anatomical structures interactively through virtual dissection. Thirty-two senior-class students from two German high schools with no prior formal medical training were separated into two groups and tasked with answering an anatomical questionnaire. One group used traditional anatomical textbooks and the other used the immersive virtual reality atlas. The time needed to answer the questions was measured. Several weeks later, the participants answered a similar questionnaire with different anatomical questions in order to test memory retention. The VR group took significantly less time to answer the questionnaire, and participants from the VR group had significantly better results over both tests. Based on the results of this study, VR learning seems to be more efficient and to have better long-term effects for the study of anatomy. The reason for that could lie in the VR environment's high immersion, and the possibility to freely and interactively explore a realistic representation of human anatomy. Immersive VR technology offers many possibilities for medical teaching and training, especially as a support for cadaver dissection courses.

Learning through VR gaming with virtual pink dolphins for children with ASD

Autism Spectrum Disorder (ASD) is a developmental disorder with different levels of severity. Although the exact causes of ASD is not yet known, nor is there a medical cure for ASD to date, special facilities and schools have been established to help individuals coping better and becoming more independent. With the advancement in Virtual Reality (VR) technology, there has been a greater depth of development of technology-enhanced game-based learning for children with ASD. This paper will describe our effort on virtual pink dolphins to assist children with ASD in their learning, at the same time, to avoid the use of physical pink dolphins which is a species endangered. A study on the use of a low-cost VR enabled pink dolphins game for children with ASD to learn direction following, psychomotor skills and hand-eye coordination will be reported.

Research into Practice: Current Trends in Educational Technology Research: The Study of Learning Environments

Educational technology research has passed through a number of stages, focusing, in turn, on the content to be learned, the format of instructional messages, and the interaction between computers and students. The field is now concerned with the study of learning in complete, complex, and interactive learning environments. These environments allow both the simulation of experiences that students might have in the real world and also the creation of compelling experiences that cannot normally be experienced directly. Learning environments also often allow students to communicate their own ideas with the use of a variety of symbol systems. These environments are also frequently inhabited by more than one person, making learning within them a social activity where learning is distributed among both people and artifacts. Finally, these learning environments are complex. Studying how they contribute to learning therefore requires research methods other than controlled experiments. This paper reviews research on learning environments to give both an historical perspective on educational technology research and a selective view of the current state of the discipline. It concludes by identifying implications for both practice and future research.

Experimental Comparison of Virtual Reality with Traditional Teaching Methods for Teaching Radioactivity

Research at the University of Nottingham has been carried out to investigate the potential of Virtual Reality (VR) for teaching secondary school science. This paper describes the evaluation of VR to teach radioactivity at secondary school level. Evaluation was carried out in a local school and compared directly to the traditional teaching methods currently used in the school to teach radioactivity. Computer experience, computer attitudes, general attitudes and knowledge gained were measured to allow comparisons to be drawn. Individual differences of gender, ability and home computer use were also looked at in relation to the above measures. Results indicated that both ability level and the order in which the conditions were completed significantly affected the attitude scores. High ability students reported higher attitude scores, both overall and for the VR class in particular. As a result of the evaluation study, the Virtual Laboratory has been heavily modified and further evaluation studies were then carried out.

Game-Based Learning in Virtual Worlds: A Multiuser Online Game for Medical Undergraduate Radiology Education within Second Life

Game-based learning can have a positive impact on medical education, and virtual worlds have great potential for supporting immersive online games. It is necessary to reinforce current medical students' knowledge about radiological anatomy and radiological signs. To meet this need, the objectives of this study were: to design a competition-based game in the virtual world, Second Life and to analyze the students' perceptions of Second Life and the game, as well as to analyze the medium-term retention of knowledge and the potential impact on the final grades. Ninety out of 197 (45.6%) third-year medical students voluntarily participated in an online game based on self-guided presentations and multiple-choice tests over six 6-day stages. Participants and non-participants were invited to perform an evaluation questionnaire about the experience and a post-exposure knowledge test. Participants rated the experience with mean scores equal to or higher than 8.1 on a 10-point scale, highlighting the professor (9.5 ± 1.1; mean ± SD) and the virtual environment (8.9 ± 1.1). Participants had better results in the post-exposure test than non-participants (59.0 ± 13.5 versus 45.3 ± 11.5; P < 0.001) and a lower percentage of answers left blank (6.7 ± 8.4 versus 13.1 ± 12.9; P = 0.014). Competitive game-based learning within Second Life is an effective and well-accepted means of teaching core radiological anatomy and radiological signs content to medical students. The higher medium-term outcomes obtained by participants may indicate effective learning with the game. Additionally, valuable positive perceptions about the game, the educational contents, and the potential benefit for their education were discovered among non-participants.
