만 4, 5세 유아의 수학적 표상활동이 비형식적 더하기 및 빼기에 미치는 영향 = The Effect of Mathematical Representation on the Informal Addition and Subtraction of 4- and 5-year-olds

다국어 초록 (Multilingual Abstract)

This study examined the effect of mathematical representation activities on the achievement of informal addition and subtraction problems of young children. Eighty 4 and 5 years old children were randomly assigned to the experimental and control groups. The experimental group was encouraged to represent mathematical ideas or problem solving precesses on the paper while working on informal addition and subtraction problems and the control group was asked to solve addition and subtraction problems without any representation activities. The results showed that the experimental group of 4-year-olds outperformed the control group on the informal addition problems and the experimental group of 5-year-olds outperformed the control group on the informal addition and subtraction problems. We can conclude that young children can benefit from mathematical representation activities while working on the informal mathematical problems. Thus, the mathematical representation activities should be encouraged for young children to use to solve the informal mathematical problems.
