Development of Rubric and Teaching Method for Mathematical Thinking

Abstract

　　The purpose of this research is to develop a method to evaluate ideas to solve problems at the time of mathematics classes at junior high school and to make a practical report. Therefore, the following method was developed. First of all, we identified the “mathematical way of thinking” that students would use when solving problems by learning of second-grade figures. And I created a unit guidance plan based on that “mathematical way of thinking” and worked on the evaluation from the perspective of “mathematical thinking”. Next, we decided on the criteria of evaluation more specifically when we conduct evaluation activities in each lesson. This criterion is also shown in the “personal evaluation card” used by students. I used this card to repeat the evaluation of “mathematical thinking” in class.

　　In doing so, students began to recognize the “mathematical way of thinking” that can be acquired in the process of solving problems. Regardless of the success or failure of the problem, the students were able to recognize the value of expressing their own ideas.
