中学校理科におけるイオンの電気泳動実験に関する研究―泳動距離の測定方法の開発と実験条件の検討―

抄録

The purpose of this study was to develop a viable electrophoretic experiment method suitable for teaching students in lower secondary school science classes. We developed a method to measure the electrophoretic migration distance of both hydrogen and hydroxide ions. By using this method, we examined various experiment conditions and then developed an experiment kit that would operate successfully within these conditions. We then tried the kit in several authentic teaching scenarios and concluded that; a) The kit is safe and easy to use and b) It was expected that the kit and its associated teaching materials are suitable for teaching students in lower secondary school science classes.
