수학 익힘의 삽화 기능 및 문제 해결시 삽화에 대한 학생의 인식 분석

Abstract

In math problems, the pictures are often presented along with the text of the problem. The pictures in math problems play various functions to help or sometimes interfere with students' problem-solving. In order to examine the functions of pictures for successful problem-solving, functions of the picture presented in the first-year mathematics workbooks, the problem-solving process of the 3rd graders, and their perceptions were analyzed. The result of the analysis shows that the functions of pictures were widely used in the order of information, organization, representation, and decoration in both the first and second semesters. In addition, the number of pictures used in the second semester decreased compared to the first semester, and informational pictures appeared the most in all content domains. As for the perceptions of 3rd graders about pictures, they responded that pictures help solve problems in the order of informational, organizational, representational, and decorative functions, which is consistent with the degree of their contribution to problem-solving. Moreover. the problem including the picture was preferred regardless of the function of the picture. Based on the results of this analysis, some didactical implications were proposed for including the pictures in the math textbook or workbook and for using the pictures to guide students to problem-solving.
