碩士 === 國立臺灣師範大學 === 工業教育學系 === 97 === This study mainly investigates the units of basic electricity alternating current where vocational high school students have difficulties with learning. In order to improve the learning effect, a basic electricity network-learning system is designed. Moreover, a nonequivalent quasi-experimental instruction is implemented, and the learning effect of network learning is compared with that of traditional learning. The first stage of this study administered a questionnaire, and aimed to identify the difficult units of basic electricity for students in electrical and electronic cluster of vocational high school. 173 third graders from Taipei Municipal Daan Vocational High School, Hujiang High School, and Muzha Vocational High School were randomly selected. It was found the most difficult unit was “Single-Phase Three-Wire and Single-Phase Two-Wire”, followed by “all types of Three-Phase Power circuit and its related calculation”, and “RLC series and parallel resonant circuits” . Then a Web-based learning system was designed to deal with those difficult units. In the second stage of this study, instruction was carried out. Participants included one control group that consisted of 38 students, and one experimental group of 41 students. Subsequent to four-week instruction, an analysis of the learning effect was conducted. Results showed that the learning effect of network learning was significantly higher than that of traditional learning. Therefore, the online learning system on basic electricity alternating current can serve to improve the current learning units for students in electrical and electronic cluster of vocational high school.
