 note = {Although digital products such as a smartphone, a digital TV, and so on, are prevailing in nowadays, most of junior high school students don’t fully understand the characteristics of analog/digital signals. On the background of the recent progress in information technology, it becomes compulsory to teach the subject of measurement and control using a program in junior high schools. For this requirement of the information technology education in junior high schools, we develop the teaching material for analog/digital study. This teaching material mainly consists of a cylindrical container, a wooden frame with graduations, and an electrical circuit. The cylindrical container is hollow, and a thin disk inside the container can move up and down continuously in this hollow part. The real motion of the thin disk corresponds to an “analog signal”. On the other hand, the position of the thin disk is measured with a sensor, which is equipped at the top of the cylindrical container. There are 8 graduations in the frame. Three LEDs are installed on each graduation. The LEDs on graduations can be gleamed discretely followed by the output voltage from the sensor, which corresponds to a “digital signal”. In parallel to the development of the teaching material, the method of its application to the classes in information technology is also investigated. The analog/digital study is essential for the subject of measurement and control using a program. Therefore, it is considered that the characteristics of analog/digital signals should be firstly taught as a basis of this subject. The preliminary guidance plan for teaching the characteristic of analog/digital is reported in this article.},
