The development of mobile AR-based module for teaching and learning pneumatic system: a needs analysis

Abstract

Practical skills and theoretical knowledge are vital competencies that technical and vocational trainees need to master before joining the industrial workforce to perform tasks efficiently. Therefore, comprehensive instructional materials and training equipment are essential to ensure that the skills and knowledge are delivered effectively to trainees. This study aimed to identify the need to develop a mobile augmented reality module to teach and learn pneumatic systems in Malaysian vocational colleges. Descriptive research was conducted to determine the module's need, involving 13 subject-matter experts from various vocational colleges. A set of questionnaires consisting of three main themes: the need for the module, the module's user interface design, and the module's usability criteria with 49 items was used. The data collected were analysed using the Fuzzy Delphi Method. All three constructs showed high levels of expert consensus of more than 75% and a threshold value of ≤ 0.2. Therefore, experts agreed that there was a need to develop a mobile AR-based module for teaching and to learn pneumatic systems with the stated user interface designs and usability criteria.
