DEVELOPMENT OF PRACTICAL TEACHING WITH A PRACTICE KIT FOR SPLIT TYPE OF SOLAR AIR CONDITIONING SYSTEM

This research aimed to improve teaching and learning with split-type solar air conditioning system practice kit. The sample group for this research comprised of 23 students from Mechanical Engineering Program, Faculty of Engineering, Rajamangala University of Technology Lanna Phitsanulok, selected by purposive sampling. The tool used in this research was a split-type solar air conditioning system practice kit. The research started with the study of data and theory related with solar air conditioning system, followed by the development of practice kit, teaching publications, and quality assessment form. The practice kit was assessed by five experts which revealed that both the practice kit and the teaching publications had the highest quality. After that, the practice kit was used in teaching and learning of the selected sample group. Practice scores gained from during-learning and post-learning were statistically analyzed to find efficiency, as well as students’ satisfaction with the teaching and learning. Results of the research indicated that teaching and learning efficiency using the practice kit was 89.28/90.18, which was higher than the defined criteria of 80/80. Average students’ satisfaction with the teaching and learning was in the highest level (x̅ = 4.51, SD = 0.55).
