Abstract

This study is to setup a mathematics PBL model that is right for elementary students. PBL models are developed and applied to actual courses and analyzed. So, a specific plan and practical understanding of PBL mathematics textbooks will be presented. But in order for this to happen, first the mathematics PBL model, that can realize 7th revised curriculum's goal, needs to setup and divided into knowledge, skill and attitude domains. Through this study, the general PBL model and the PBL model appropriate for elementary mathematics was amended and supplemented, this was then applied to courses and analyzed, and the below conclusions were realized. First, mathematical idealization stage is needed for mathematical PBL model. Since an elementary student is shortcoming in problem understanding and mathematical activity, a middle step that allows the student to understand the problem situation mathematizing and find a solution mathematically is desperately needed. Therefore, in this study, we named it the mathematical idealization stage and had it setup. Second, a mathematics information collection stage needs to be prepared for a successful PBL. Through this stage, the students will have an opportunity to gather the necessary information needed and restructure it to solve the problem. Third, the organization stage in mathematical PBL model needs to be strengthened. PBL is not just completed, through the best use of mathematics subject matter to solve the problem. Organization time is needed to allow the students to grow to a more deepened and advanced level. In conclusion, there is significance in providing a specific plan for mathematical PBL model, which can be seen through this study on applying and analyzing elementary mathematics and appropriate PBL models.

본 연구는 초등학생에게 알맞은 수학과 PBL(문제중심학습)의 목표와 모형을 개발하여 실제 수업에 적용 분석함으로써 수학 교과에서의 PBL에 대한 실천적 이해와 구체적인 방안을 제시하는 것을 목적으로 한다. 본 연구는 7차 개정 수학과 교육과정의 목표를 구현할 수 있도록 지식, 기능, 태도 영역으로 구분하여 10가지 목표를 설정하고 수학과 PBL 목표 기준을 표로 제시하였다. 또한 기존의 PBL 모형을 수정 보완하여 초등학교에 적합한 수학과 PBL 모형을 개발하고자 수학적 의미화, 수리 정보 수집 단계를 추가하고 정리단계를 강화한 초등학교 수학과 PBL 모형을 제시하였다. 이를 초등학교 4학년 소수 단원에 두 차례의 현장 적용을 하는 동안 4명의 개별 학생들의 수학과 PBL 목표 도달여부와 반응을 살펴보았다.
