Abstract

The purpose of this research is to suggest the method of code analysis for evaluating learners' projects in computational thinking(CT) education. Recently, block programming tools are applied to K-12 SW education, this study considered the assessment method for evaluating students' levels and learning about CT concepts through analyzing codes of the Scratch projects that students created. As a result from the analysis of 45 projects of novices, it showed the bad coding patterns of novices and verified that it is possible to evaluate students' learning about CT concepts through the analysis of their codes. The higher learner's level, the greater scores of logical thinking, synchronization, flow control, and data representation. This result is able to apply to student assessment of CT concepts in K-12 SW education.

본 논문의 목적은 Computational Thinking(CT) 교육에서의 학습자 평가를 위한 방안으로 학습자가 제작한 프로젝트의 코드를 분석하는 방법을 제안한다. 최근 초중등 SW교육에서는 블록형 프로그래밍 도구를 활용한 교육이 이루지고 있으므로, 학생들의 산출물인 스크래치 프로젝트의 코드를 분석하여 CT 개념 습득과 학습자의 수준을 평가하는 방안을 모색하였다. 초보학습자 45명의 프로젝트를 분석한 결과 초보학습자들의 잘못된 습관에 대한 패턴이 나타났으며 CT 개념 학습을 코드의 패턴에 의해 평가할 수 있다는 것을 검증하였다. 학습자의 수준이 높을수록 논리적 사고, 동기화, 플로우 제어, 데이터 표현의 요소 점수가 높게 나타났다. 본 연구의 결과는 초중등 SW 교육에서 CT 개념 학습에 대한 평가를 위해 활용할 수 있다.
