Applying instructional APPs and the cloud platform to solve students' learning problems in core specialized courses of refrigeration and air conditioning in vocational high schools under the 12-year national fundamental education system

The purpose of this study was to explore whether ninth grade students can fulfill the requirements of course objectives for each subject in a technology high school due to the different enrollment methods after the practices of the 12-year national fundamental education system and to examine their learning characteristics (such as learning attitudes, learning difficulties, etc.) to serve as reference for teachers of all subjects when designing courses and actually teaching students. Taking core specialized courses in refrigeration and air conditioning as an example, a teaching experiment was then developed to help students learn before, during, and after class and adopted the learning management system provided by cloud platform and related digital teaching materials that it has designed and developed in order to assist students in solving the problems that they encounter during learning. Finally, the results were analyzed and synthesized to serve as a reference for applying cloud platforms and digital e-learning in all technology high schools aiming to enhance the learning effects of students enrolled in the 12-year national fundamental education system.
