Abstract

In order to improve computational thinking, elementary schools have been using 'Scratch' to provide basic programming education. However, the study on evaluation of computational thinking is at an early stage. Therefore, this study evaluated the conceptual level of computational thinking using the scratch code analyzing. For this, Dr. Scratch was used to analyze 179 scratch projects. The results showed that the conceptual level of computational thinking of most elementary students was at the developing level, and that it varied according to gender and production style, showed the lowest level of logic and abstraction, and improved computational thinking during programming. This study is meaningful in that it provides implications for the improvement of teaching methods and self-directed evaluation in learning.

컴퓨팅 사고력을 향상시키기 위해 초등학교에서는 블록형 프로그래밍 언어인 스크래치를 활용한 기초 프로그래밍 교육을 하고 있으나 컴퓨팅 사고력에 대한 평가 연구는 초기 단계이다. 따라서 본 연구에서는 스크래치 프로젝트의 코드를 분석하는 방법을 활용하여 초등학생들의 컴퓨팅 사고력의 개념 수준을 평가하였다. 이를 위해 스크래치 코드 분석 자동화 도구인 Dr. Scratch를 활용하여 초등학교 6학년 학생들이 제작한 179개의 스크래치 프로젝트를 분석하였다. 연구결과 초등학생의 컴퓨팅 사고력의 개념수준은 개발자 수준이 많았고, 성별과 작품유형에 따라 차이가 있었고, 논리와 추상화 요소에서 가장 낮은 수준을 보였으며, 프로그래밍 과정에서 컴퓨팅 사고력이 향상되는 것으로 나타났다. 본 연구는 초등학생의 프로그래밍 학습에서 교수방법의 개선과 자기주도적 컴퓨팅 사고력의 평가에 대한 시사점을 제공한다.
