The purpose of mathematics education includes two important areas; cognitive area that emphasizes mathematical knowledge and understanding and affective area that stresses mathematical interest and attitude. The purpose of mathematics education is not only in acquiring the contents and knowledge but also rousing up interest and attention toward mathematics. Therefore, effort to accomplish this affective purpose has to be made. Introducing history of mathematics to teaching can be a important method for the students to arouse interest and attention toward mathematics. History of mathematics can help the students who are familiar to only manipulation of the symbols to develop a new way of thinking and mathematical thoughts arousing reflective thinking. According to the survey, although the effect of using mathematics history has been recognized, the mathematics history has neither been developed as teaching materials nor reflected in the courses of study. The purpose of this research is to develop the reading materials into suit for the mathematics curriculum to extract contents of the mathematics valuable in using in elementary mathematics teaching, and to investigate the effect of reading materials using the history of mathematics on learning attitude in elementary school. The way of developing materials in this study is as follows. First, to select the interesting and instructive subject for the elementary students such as the story and life of a mathematician, developmental stages of mathematical theory and calculation currently used and finding the patterns of the rules that requires mathematical thoughts. Second, to classify the selected items according to mathematics curriculum. Third, to reorganize the classified items of the appropriate grade with the reading materials of dialogue pattern in order to draw attention and interest from the students I developed 18 kinds materials in accordance with the above procedure and applied 5 materials among them to one class in 4th grade. Analysing the student's responses, First, using history of mathematics helps the students to arouse interest and confidence on mathematical learning attitude. And the students became better attitude of studying by oneself and attention on class. Second, as know by opinions after lesson, most students have a chance refresh one's thinking of mathematics, want to know the other content of history of mathematics and responded to study hard in mathematics. As a result, the reading materials on the basis of the history of mathematics motivates students for mathematics and helps them become confident in mathematics. If the materials are complemented properly, they will be useful and effective for students and teachers.

본 연구는 가상 수업 상황극인 레슨 플레이(Lesson Play)를 활용하여 예비교사 교육에서의 활용가능성을 탐색하고, 이를 활용하여 예비교사의 교수학적 지식을 탐색하기 위해 시행되었다. 레슨 플레이는 상상할 수 있는 수학 수업의 모든 상황을 연극 대본처럼 글로 써보는 방법이다. 본 연구는 서울 소재의 한 사범대학 수학교육과에 재학 중인 예비교사 20명을 대상으로 91을 소수라고 답한 학생, 462가 4의 배수라고 답한 학생에 대한 교사의 발문으로 시작하여 그 이후에 이루어질 교사와 학생의 대화를 구성하도록 하였다. 예비교사의 가상 대본을 통해 다음과 같은 결론을 이끌어낼 수 있었다. 첫째, 예비교사의 교수 전략은 다양하지 않았다. 둘째, 수학적 개념 또는 원리를 중심으로 설명하고자 하였다. 마지막으로 학생이 무엇을 어려워하는지 알지 못한 채 교사와 학생의 발문을 구성하였다. 따라서 레슨 플레이는 예비교사의 교수학적 지식의 분석과 함께 실천적 지식을 향상시키는 교수방법으로 활용 가능함을 알 수 있다.
