Development of Laboratory-Based Learning and Teaching Activities of Communication Systems for 21st Century Innovative Learning Skills

This paper presents the development of Laboratory-Based teaching and learning activities of communication systems to promote functional skills in the 21st century. The research process consists of 1) exploring the needs needed to develop teaching and learning in the 21st century; 2) developing the SLDEA Laboratory-Based learning model consisting of 5 steps: Searching, Learning, Exchanging, Doing, and Assessment; 3) creating the instructional package to be as a research tool including a teacher's manual, a simulator, an experimental set of antennas, experimental set of the radio transmission system, a learning achievement test; and 4) implementing the research tools to be used with a sample group of 20 undergraduate students in the semester 2/2023 in the Bachelor of Science in Technical Education, Department of teacher training in electrical engineering at the King Mongkut's University of Technology North Bangkok, Thailand. The findings showed that 1) the quality of the research tools developed by five experts was at a high level of appropriation; 2) the learners’ learning achievement had an average of 73.54% and 3) the learners’ satisfaction level with Laboratory-Based teaching and learning activities of Basic Communication Systems was at a high level. Therefore, it can be concluded that the learning activities developed can encourage learners to have practical skills in the 21st century and have experiences in self-learning and lifelong learning. This skill can lead to the creation of innovations and technologies that can support the industrial sector in the 4.0 era.
