Abstract
In engineering education Virtual Reality (VR) and Augmented Reality (AR) technologies have been recently adopted in the teaching of technical subjects showing good potential for visual interaction with the objects. This study aims to investigate the effect of using a specifically developed mobile AR Engineering Drawing (ED) application (Apps) for improving the cognitive learning levels of students and learning achievement. In this study, experimental design with pre-test and post-test control groups and interview were used to measure of participants’ success. For this purpose, a total of 30 participants involved in the experimental group used AR application for training, whereas another 20 participants without AR training were kept as a control group. The increase in performance between pre-test and post-test was 39.7% for the experimental group and 17.2% for the control group. The results indicated a 19.6% higher learning performance in the experimental group through the use of the AR application for training. This result shows the very important effect the mobile AR engineering drawing application had in terms of acquiring new knowledge and skills on the participants. The study also shows that teaching Engineering Drawing subjects using AR Apps significantly increases students' conceptual and cognitive comprehension levels.
Highlights
Nowadays, the quick integration of vocational education graduates into industry is of great importance for companies in terms of economic gain and production performance
It was observed that both groups were at the same level in the preliminary tests which included questions about the basic technical information for a drawing, the shapes and tolerances given on an Engineering Drawings
The increase between pre-test and post-test was 39.7% in the experimental group and 17.2% in the control group. These results indicate 19.6% higher learning performance in the experimental group compared to the control group
Summary
The quick integration of vocational education graduates into industry is of great importance for companies in terms of economic gain and production performance. There are concerns from industry about the decline in standards of production due to the lack of understanding of technical drawings standards (Huerta et al 2019) This deficiency is due to the fact that the training given in high schools, vocational schools, and engineering faculties is not well supported with practical applications that can be used along traditional teaching methods for large groups to give an opportunity to students to quickly update practices or standards (Arslan & Uzaslan, 2017). The results of the study showed that the students who had the opportunity to learn with the developed AR-based system demonstrated higher learning motivation and had better learning performance and comprehension abilities than those who worked with traditional teaching approach
