Profile 2002-2004: Instructor, Faculty of Integrated Media, Wakkanai Hokusei Gakuen University;
2004-2009: Associate professor, Faculty of Integrated Media, Wakkanai Hokusei Gakuen University;
2010-2020: High School Mathematics Teacher;
2020-present: Professor, Faculty of Liberal Arts and Sciences, Tokyo City University.

In the faculty of education, Hokkaido University, and the master's and latter doctoral course in Graduate School of Education, Hokkaido University, I have learned the basics of educational methodology study based on educational content and teaching material construction. Focusing on mathematics education in particular, I have been involved in study to make concrete proposals that contribute to lesson planning with colleagues in the laboratory specializing in language education, science education, social science education, etc. In the bachelor's and master's courses, I studied how to teach the concept of probability. Since the latter doctoral course, the main theme has been study on curriculum reconstruction of geometry education in elementary, junior high and high schools.

When I was an undergraduate and graduate student, I was taught that educational study is in line with the field of education. I have participated in study sessions for elementary and junior high school teachers hosted by my academic advisor. In addition, I have visited study groups consisting mainly of teachers to present my own teaching theory and lesson plans and have them consider it. As a result, some teachers have put my lesson plans into practice, and such joint study activities with teachers are still ongoing. Currently, I am the representative of the Hokkaido branch of AMI (The Association of Mathematics Instruction), a private study organization whose members are mostly teachers.
Research Field(Keyword & Summary)
  1. (1) Educational Methodologies Based on Subject Education

    Some of the educational methodological theories applicable across subjects will soon be found. However, things that anyone can think of immediately, such as "let's write on the board in beautiful letters" and "let the students think," are too obvious and almost useless. I think that the really important educational methodological theory is inside the subject education. Only steady study that analyzes and creates excellent educational practices in a subject from both the educational content and the lesson process will enable the advocacy of one hypothetical theory in educational methodology.

  2. (2) Content and Material in Mathematics Education

    I set themes such as similarity, probability, and trigonometric functions from mathematics education, and construct an easy-to-understand and fun lesson that teaches their essence. This study is conducted in collaboration with teachers as practitioners and students who aspire to be them. We also develop teaching tools that enrich mathematical recognition. There are two aspects in the study. One is the theoretical aspect of constructing subject / unit lessons based on educational content theory and cognitive formation theory, and the other is the empirical aspect of verifying the validity of the lesson process and teaching material composition by analyzing experimental lessons.
