Abstract

We have developed a UMC (Use-Modify-Create) strategy for the improvement of computational thinking in SW education. UMC model is an instructional strategy that students analyze examples of algorithms, modify-expand it and to develop new SW. First, we applied the UMC classes during 1 semester targeting pre-service teachers. To explore the effectiveness of the proposed model, we conducted a t-test for improving students' self-CT. Through a result, we found that is the UMC teaching-learning strategy helped the CT concepts and practice skills. In addition, we could see the Use and Create steps help to improve the ability of students' CT than directly teaching and Modify steps.

본 연구에서는 SW교육에서 Computational Thinking의 향상을 위한 놀이활동 중심의 UMC(Use-Modify-Create) 전략을 개발하였다. UMC 수업 전략은 학생들이 예제 알고리즘을 분석하고 이를 수정, 확장하여 새로운 SW를 개발하는 모형이다. 먼저 예비교사를 대상으로 1학기 동안 UMC 수업을 적용하였다. UMC전략에 대한 학생들의 self-CT 향상에 대한 t-검사 결과, UMC 수업전략이 CT개념과 실습능력에 도움을 주었다. 또한 Modify 단계와 직접교수식 단계보다 Use단계와 Create 단계의 탐색과 자기주도적 개발과정이 CT능력 향상에 도움을 주고 있음을 알 수 있었다.
