본 연구는 수개념 영역을 제외한 3개의 수학 영역인 사물의 규칙성, 기하, 측정에서 유아의 수학과제 해결전략 유형을 파악하여 계열화ㆍ범주화하는데 그 목적이 있다. 사물의 규칙성 영역에서 분류과제는 사물과제에서 5개의 유형의 과제 해결전략이, 도형영역에서 6개 유형의 과제 해결전략이 나타났으며, 서열과제에서는 길이와 넓이 과제 각각 5개 유형의 과제 해결전략이 나타났다. 패턴과제의 경우 2가지의 다른 질적 특성을 가진 과제 해결전략이 나타나 패턴이 가지는 속성 자체에 대한 전략과 패턴 관계에 초점을 두는 전략이 각각 6개의 유형으로 나타났다. 도형과제의 경우 단일 기준점과 복합기준점 2개의 유형의 전략이 나타났다. 측정과제에서는 직접비교과제와 간접비교과제에서 각각 4개 유형의 전략을 범주화할 수 있었다. 3개 영역의 유아 수학과제 해결전략 유형 파악은 개별 유아에 대한 정보를 얻는데 활용될 수 있을 뿐 아니라, 유아 수학과제 해결전략 관련 연구가 다양한 수학 영역에서 활성화되는 데 기여할 수 있을 것이다.
The purpose of this study is to present the list of children's mathematical problem solving strategies and to investigate the strategies according to age and gender. The research questions for the purpose of this study are as follows: First, what aspects are shown in children's mathematical problem solving strategies in the Regularity of Object domain? Second, what aspects are shown in children's mathematical problem solving strategies in the Organizing Diagram domain? Third, what aspects are shown in children's mathematical problem solving strategies in the Measurement domain? 72 children, who are 4 and 5 year-olds, were selected from H kindergarten in Busan City. Instrument, which is a Mathematical Ability Test for Young Children introduced by Choi(2003), was used. During the test, children were asked about their thinking related with the mathematical problem solving process. The whole test and interviews were recorded by digital camera. Data were analyzed into frequency and percentage by SPSS Win 12.0. The results of this study are as follows: First, children's mathematical problem solving strategies in the Regularity of Object domain were divided into three branches: Classification, Order, and Pattern. In the Classification of Object branch the strategies were a Similarity, a Function, Commonness, Difference, and Subjectivity. In the Classification of Diagram branch the strategies were Size, Figure, Color, Size-Color, Figure-Color, and Subjectivity. In the Order of Length branch there were an Approximation, a cognition of Deviation Value, Comparison One by One, Arrayal, and Arrayal Horizontally. In the Order of Width branch there were Approximation, a Cognition of Deviation Value, Comparison One by One, Arrayal, and Piling. In the Pattern branch there were Counting, Size, Figure, Color, Figure-Color, and Subjectivity. In the Pattern branch there was one more kind of strategy than was shown. That was Symmetry, Neighboring, Repetition, Regulation, Aggregation, and Finding the Lack. Second, children's mathematic problem solving strategies in the Organizing Diagram are Single Reference Point and Complex Reference Point. Third, the Measurement domain was divided into two branches: Direct Comparison and Indirect Comparison. The strategies are Placing, Arranging with Regulation, Approximation, and Arrayal.
