A DEVELOPMENT OF AR TECHNOLOGY-INTEGRATED LEARNING MATERIALS ON THE HUMAN BODY’S ORGAN SYSTEMS FOR GRADE 8 STUDENTS

This research aimed to: 1) develop AR-integrated learning materials on the human
body's organ systems for Grade 8 students, 2) assess the quality of the AR-integrated learning
materials, 3) compare students' learning outcomes before and after using the AR-integrated
learning materials, and 4) determine students' satisfaction with the AR-integrated learning
materials. The sample group, selected through purposive sampling, consisted of 36 Grade 8
students from the Science-Mathematics program at Satri Nakhonsawan School. Data analysis
methods included independent samples T-test, standard deviation, means and percentage.
The research findings indicated that the learning materials included images, videos,
and an application incorporating AR technology. The overall quality of the learning materials,
as evaluated by content experts, was rated as good (Mean=4.45, SD=0.37). Similarly, the
overall quality of the learning materials, as evaluated by multimedia experts, was also rated
as good (Mean=4.47, SD=0.55). The effectiveness of the learning materials was measured at
89.05/81.78, exceeding the established criterion of 80/80. A comparison of pre-test and posttest
scores revealed that the pre-test scores (Mean=12.14) were 48.56%, while the post-test
scores (Mean=21.19) were 81.78%. The calculated t-value was higher than the table t-value,
indicating a statistically significant improvement in students' learning outcomes at the .05 level.
The overall satisfaction with the learning materials was rated as very high (Mean=4.55,
SD=0.67).
