Abstract

This study aimed to assess the spatial cognition strategies and roles taken by students in the process of solving spatial tasks. For the analysis, this study developed two spatial tests based on the mental rotation test, which were taken by 63 students in their final year in elementary schools. The results of this study showed that in terms of the method of approaching the tasks, students took the comprehensive approach and the partial approach. When solving the tasks, the students were shown to use the imagery thinking or analytic thinking method. In terms of perspective, the students rotated the object or change their perspectives. A comparison of the methods used by the students revealed that when approaching the tasks, the group of students who chose the partial approach had higher scores. In terms of solving the tasks the analytic thinking method, and in terms of perspective, changing perspectives were shown to be more effective. Such effective methods were used more frequently in discrimination tasks than in recognition tasks, and in more complicated items, than in less complicated items. In conclusion, the results of this study suggested that the partial, analytic approach and the change of perspectives are useful strategies in solving tasks which require high cognitive effort.

본 연구에서는 공간 과제에서 학생들이 사용하는 공간 인지 전략의 유형과 역할을 살펴보고자 Shepard & Metzler(1971)의 심적 회전 검사(mental rotation test)를 토대로 시각적 변별과 기억 능력을 측정하는 두가지 공간 과제를 개발하여, 초등학교 6학년 학생 63명을 대상으로 연구를 수행하였다. 연구 결과, 학생들은 접근 방법 측면에서 전체적 접근 전략과 부분적 접근 전략을, 처리 방법 측면에서 심상적 처리 전략과 분석적 처리 전략을, 준거 기준 측면에서 대상 변환 전략과 관점 변환 전략을 사용하였다. 사용 전략에 따른 검사 점수를 비교한 결과 접근 방법 측면에서는 부분적 접근 전략을 사용한 집단이, 처리 방법 측면에서는 분석적 처리 전략을 사용한 집단이, 준거 기준 측면에서는 관점 변환 전략을 사용한 집단의 검사점수가 더 높게 나타났다. 또한 이러한 전략은 변별 과제보다 재인 과제에서, 복잡도가 낮은 문항보다는 복잡도가 높은 문항에서 더 빈번하게 사용되었다. 따라서 부분적 접근전략, 분석적 처리 전략, 관점 변환 전략은 인지적 노력이 많이 요구되는 문제 상황에서 체계적으로 문제를 해결하도록 돕는 유용한 전략임을 확인할 수 있었다.
