Abstract
Biology is a science about living organisms. Organisms have complex systems consisting of complex organs. Focusing on the human body, if the organ or its structure is visually presented, the learners are more likely to understand it and its function. This research aims to explore the bilingual (Thai and English language), development of an augmented reality tool for use in teaching students about the human heart. The augmented reality application was evaluated by five experts, who analyzed its content consistency by using the Index of Item Objective Congruence (IOC), Diffusion of Innovation (DOI), and the content validity index (CVI), indicating that the augmented reality can be used for publicizing. A sample of 30 subjects were evaluated after AR training. It was determined that the learning result post AR obtained higher ratings when compared with the ratings prior to the use of augmented reality tool. The before and after augmented reality learning results were analyzed for statistical significance at p value < 0.001 with the use of a T-Test. Afterwards, the effectiveness of the tool was evaluated by users focusing on the acceptance of the augmented reality tool to teach the anatomy of the heart; the evaluation of which was based on the theory of Unified Theory Acceptance and Use of Technology (UTAUT) in which the results of the arithmetic mean and the standard deviation were 4.65 and 0.48, respectively. This demonstrated that the users generally accepted the augmented reality tool to teach about the heart at the highest level.
Highlights
The educational management or the lesson planning for students in this era rely on modern tools instructors to attract the attention of the learners and give the best knowledge and learning experience to the learners
From the assessment of the Content Validity Index evaluated by all the experts, it was determined that the content validity index (CVI) value was 0.83 as there were ten questions out of twelve questions receiving the scores at 3 or 4
This paper presents the development of the augmented reality tool to teach about the human heart in a bilingual setting (Thai and English language)
Summary
The educational management or the lesson planning for students in this era rely on modern tools instructors to attract the attention of the learners and give the best knowledge and learning experience to the learners. In biology class, focusing on the human body, if the organ or its structure is visually presented, the learners tend to understand it and its function better [3]. For the internal organs, it is difficult to see their shapes, sizes, structures, and functions; even though there are figures and descriptions in textbooks, related documents or on the internet, as most of them are presented in the form of two dimensional images in which their characteristics or functions cannot be clearly seen [4] In other words, this potentially affects the proficiency of the learners. Joyce reported that augmented reality magnetically tracked scalpels reduce tool switching though limitations in today's augmented reality technology fall short of creating an ideal immersive workflow by requiring the use of a monitor [8] While this technology catches up, we recommend focusing efforts on enabling the easy creation of layered, complex reports, linking, and viewing information across systems. There are no research studies on the development of augmented reality as a tool to teach the human body using Thai language
