This study aims to design an integral instruction method that follows the Abstraction in Context (AiC) framework proposed by Hershkowitz, Schwarz, and Dreyfus to help students in acquiring in-depth understanding of the relationship between indefinite integrals and definite integrals and to analyze how the students' understanding improved as a result. To this end, we implemented lessons according to the integral instruction method designed for eight 11th grade students in a science high school. We recorded and analyzed data from graded student worksheets and transcripts of classroom recordings. Results show that students comprehend three knowledge elements regarding relationship between indefinite integral and definite integral: the instantaneous rate of change of accumulation function, the calculation of a definite integral through an indefinite integral, and The determination of indefinite integral by the accumulation function. The findings suggest that the AiC framework is useful for designing didactical activities for conceptual learning, and the accumulation function can serve as a basis for teaching the three knowledge elements regarding relationship between indefinite integral and definite integral.

1960년대를 기점으로 하여 일어난 수학 교육현대화 운동은 범세계적인 문화현상으로서 발전하는 방향으로 철저히 진행되어야 했으나 교재내용을 지나치게 비현실적으로 도입함에 따라 교육의 현장에 선교사의 창조적 노력보다는 무비판적인 수학교육이 됨으로써 원래의 수학교육목표와는 달리 진도에만 급급하다. 현실적인 요인으로서 중등학교 진학률의 증가 및 평준화에 대한 원인도 있겠지만 시험에만 연결되는 교육에 이상적인 논리주의 구조주의 적인 수학의 도입도 적지않은 문제 요인으로 되어 있다. 앞으로 교과과정의 개선이 있겠지만, 우선 지도방법에 있어서 새로운 방법론이 시도되어야 할 것이다. 본 논문에선 학생들이 이해할 수 있는 범위내에서 수학사적 자료를 도입하여 수학의 역사 및 수학의 사상적 배경등에 접할 수 있는 기회를 주어 교과내용에 흥미를 유발하고 수업내용을 이해하는데 도움을 주는 방법을 모색하려는 것이다.
