Laboratory-Based Learning and Teaching Innovations of Basic Telecommunication System to Promote Practical Learning Skills in the 21st Century

This research has presented a development of innovative approach to teaching and learning basic telecommunication system laboratory in order to promote students’ 21st-century skills. Traditional laboratory-based instructional methods were unable to develop students’ practical abilities. It has failed to meet curriculum expectations, primarily due to outdated teaching models, limited integration of digital technology, and inadequate experimental equipment. To address these challenges, the research introduced the SLEDA laboratory-based learning model comprising five stages: Searching, Learning, Exchanging, Doing, and Assessment, alongside the development of modern learning media such as simulation programs, radio transceivers experiment, and antenna. A comprehensive teaching package based on radio communication principles was designed and implemented with 30 undergraduate students in the Industrial Education program, majoring in Electronics and Telecommunications Engineering at Rajamangala University of Technology Isan, Sakonnakhon Campus. Evaluated by 11 experts, the quality of instructional package was rated as highly appropriate (x̅ = 4.71, SD = 0.29), and the SLEDA laboratory-based learning model proved effective according to the E1/E2 efficiency standard (75.08/75.57). Student satisfaction was at the highest level (x̅ = 4.64, SD = 0.22), and their expected learning skills improved significantly, with averaging 84.62%. The research results show that the learning management innovation can effectively and efficiently promote learners' learning achievements in the field of telecommunications engineering. It can be used as a model that can be applied to the development of modern learning innovations that support education in the 4.0 era.
