The development of 3D interactive learning media using augmented reality technology: basic principles and instruments of dual-energy computed tomography

Abstract

The purpose of this research is to create a three-dimensional interactive learning material using augmented reality technology to educate students about the basic principles and instruments of dual energy computed tomography. The material will be built using the Unity 3D application. A special random sample procedure was utilized to choose 28 students in the second year of Radiological Technology studies at the Faculty of Medicine Prince of Songkla University. The findings revealed that the mean Content Validity Index score is 0.97, the Technology Acceptance Model score level has a mean and standard deviation of 4.67 ± 0.57, and the content and media appropriateness score level with a mean and standard deviation of 4.67 ± 0.55 all met preset requirements and were approved by three experts. At the 0.05 significant level, the students' achievement score after using the application level with a mean and standard deviation of 17.68 ± 1.83 was higher than before using it 8.50 ± 2.72, the students' satisfaction with the learning media score level with a mean and standard deviation of 4.58 ± 0.76 and the Technology Acceptance Model score level with a mean and standard deviation of 4.78 ± 0.44. In conclusion, the development of this education tool can support learners in visualizing information in three dimensions and in better understanding the fundamental concepts and equipment of dual energy computed tomography.
