Distance Learning by Video Conference System

Abstract

Learning through the experimental experience is a helpful way for students to master a science subject. However, it is difficult to do experiments in electrical learning as the high voltage and large electronic current are dangerous. This paper presents a new teaching style of science experiments between the research laboratory of an electric power company and the experimental room in a lower secondary school. At first, studens do electric experiments using a Faraday cage and study electric current, the electric shock and the function of earth line. After the experiments, the students try to understand electricity and ask the researcher details of electricity through the video conference system. They can also confirm their knowledge about electricity through observing the thunderbolt experiment with a high voltage generator in the research laboratory. This system is useful for students to learn about real electric phenomenon.
