Educational Practice in Electric Theory Using Hands-on Approach for Technology Teacher Training

The purpose of the study was to practice teaching electric theory to first graders using a hands-on approach in a technology teacher training course at a teacher's education university, and to verify the effect. Hands-on activities included simple electrical experiments and simulations in a lecture room. To allow time for hands-on activities, flipped classrooms were used as a teaching method. In the flipped classroom, students were required to watch the video lectures in advance and then engaged in hands-on activities. Fifteen lessons were taught, and the effect was examined based on test and questionnaire results of the group using the hands-on activities (experimental group) and a group without the activity (control group). The results showed that the average score of the short tests and regular examinations was significantly higher than that in the control group, except in the case of the AC circuit field. Thus, the experiments and simulations contributed to improved interest and comprehension, therefore, demonstrating the educational effect of the hands-on approach. © 2023 The Institute of Electrical Engineers of Japan.
