The Development of Learning and Exercising Set for Wi-fi Signal Source Finding Tools under the Project for Promoting Telecommunication Engineering Education in Schools Nationwide (WiFinder)

Abstract

This article studies the development and assessment of the Wi-Fi signal source finding tools under the “Project for Promoting Telecommunication Engineering Education in Schools Nationwide (WiFinder).” With an applied experimental method, the study used the telecommunication engineering concepts, such as wave theory, radio transmitters, antenna and wave propagation, transmission lines, signal finding tools functions and Wi-Fi signal source creation with mobile phones, to design the Wi-Fi signal source finding tools. The tools effectiveness was then tested by teachers, students, and educational personnel from 500 institutions nationwide who met the selection criteria. The study found that by applying basic telecommunication engineering theory and materials available at hand, the Wi-Fi signal source finding tools could be easily and worthy developed and used. Functions of the intangible and invisible radio wave could be demonstrated for understanding among the students. The tools were therefore suitable for teaching of telecommunication engineering in schools, noticeable from their better understanding on telecommunications. The post-training assessment of all participating institutions increased at 34.03 percent. In addition, the participating institutions continued to transfer the knowledge in their teaching activities at an average time of 4.16 hours.
