초록

본 연구에서는 그릿 검사가 초등수학영재를 판별하는 도구로서 타당성에 대하여 검증하고자 하였다. 이를 위하여 문헌 연구를 통하여 선행 연구들에서 그릿 검사의 측정 도구들에 대한 자료를 수집하였고, 전문가 검토를 통하여 영재판별을 위한 판별 문항을 개발하였다. 본 연구를 위해 서울특별시 초등학교 일반학생 39명과 영재교육원 수학영재 20명을 대상으로 그릿 검사, 수학 문제해결력 검사, 수학 창의성 검사, 수학 행동 특성 검사를 실시하여 상관관계를 분석하였다. 상관관계 분석 결과 그릿 검사는 수학 문제해결력 검사와 0.521, 수학 창의성 검사와 .440, 수학 행동 특성 검사와 .601의 상관을 갖는 것으로 나타났으며, 모두 유의확률 p<.01 유의도를 보였다. 또한 판별 분석을 통하여 집단 판별의 유의성을 검증한 결과에서 그릿 검사는 집단 내 분산을 총 분산으로 나눈 Wilk's λ가 .799로 나타났으며 유의확률은 p<.001로 그릿 검사가 수학영재와 일반학생을 판별하는데 유의함을 확인하였다. 연구 결과, 그릿 검사가 초등수학영재를 판별하기 위한 대안적인 도구로 타당성이 검증되어 수학영재 판별 도구로 활용 가능할 수 있음을 나타낸다.

The purpose of this study was to find out whether the Grit test is valid as a test tool for Identification of mathematically gifted elementary students. For this study, we conducted Grit tests, Mathematical Problem Solving Aability Tests, Mathematical Creative Ability Tests, and Mathematically Gifted Behavior Characteristic Tests on 39 ordinary students at Seoul public elementary school and 20 mathematically gifted students at the Education Center for Gifted Education, and analyzed correlation with each test. In addition, we conducted a discriminant analysis to find out how the Grit test can accurately determine the members of the mathematically gifted student group and the ordinary student group. As a result of Pearson's correlation analysis, the Grit test was .521 with the Mathematical Problem Solving Ability Tests, .440 with the Mathematical Creative Ability Tests, and .601 with the Mathematically Gifted Behavior Characteristic Tests, according to significant positive correlation at p<.01. Through this, it can be confirmed that the Grit test has a high official validity as a tool for determining mathematically gifted students. As a result of conducting a discriminant analysis to confirm the classification discrimination ability of the elementary mathematically gifted student group and ordinary student group of the Grit test, Wilk's λ was .799(p<.001). We confirm that the Grit test is a significant variable in determining the mathematically gifted student group and ordinary student group. In addition, 64.4% of the entire group was accurately classified as a result of group classification through discriminant analysis. This shows that the Grit test can be actually used as a test tool to determine mathematically gifted elementary students.
