Abstract
In the textbook for the teaching of technology studies at junior high schools, studying the role of information processing methods, raised at the beginning of the course, aims to provide an introduction to "B information and computers" and stimulate a desire to study. Some examples of information processing are given, however students mainly learn from textbooks, with no practical experience. Using only a textbook, students are unable to completely understand the content and lose interest in the subject. So, by incorporating practical experience with a POS system into the course with the aims of ensuring student's understanding of course content and raising their level of interest, a new study plan was developed. Upon investigation, this course was found to be effective in accomplishing these goals.
