Abstract
We are living an era in which we can easily obtain much information by using various technologies. In this era, it is necessary to develop competencies and skills for effective problem solving, such as identifying problems by oneself, learning by oneself, thinking by oneself, deciding independently, and improving the process of problem solving. The development of these skills must be supported by education as early as possible. A research has officially started on developing these skills in the Japanese educational system. On the other hand, Japanese QC and Japanese industry have developed know-how for effective problem-solving based on data. And these effective problem-solving activities are being completed by QC Circle. In this paper, the aim is to support development of skills for problem-solving based on data from primary school students by applying QC methods. This paper also presents a case study by which students can learn how to solve or improve a problem.
