Abstract

As SW education has become essential since 2018 due to the revised curriculum in 2015, researches on SW education are actively being carried out. In order to understand the level of pre-service teachers' computational thinking level, we analyzed a correlation of CT element scores with each year and each grade based on the calculated Scratch project by years using the analysis tool Dr. Scratch, which was targeted for 325 students in K National University of Education who passed the scratch course from 2016 to 2018. The result indicated that there is a positive correlation between all the CT related factors and both the year and the grade. Conclusionally, it is crucial to have students undergo revising process by using an automated evaluation tool such as Dr. Scratch and cultivate ability to create and utilize required materials. Furthermore, it is necessary to educate students to utilize logical thinking elements such as complex conditions and logic operations.

2015 개정교육과정에 의해 2018년부터 SW 교육이 필수화되면서 SW 교육에 대한 연구가 활발하게 이루어지고 있다. 본 논문에서는 예비교사들의 컴퓨팅 사고력 수준을 파악하기 위해 2016년부터 2018년까지 3년 동안 K 교육대학교 1학년 학생 325명을 대상으로 스크래치 수업을 실시한 후 연도별로 산출된 스크래치 프로젝트를 Dr. Scratch 분석도구로 평가하여 연도별과 학점별로 CT요소 점수의 연관성을 분석하였다. 그 결과, 연도와 학점이 높을수록 CT요소, 점수, 등급도 높아짐을 알 수 있었다. 이를 통해, 학생들은 Dr. Scratch와 같은 자동화된 평가도구를 사용하여 평가해 본 후 스스로 수정 보완해보는 과정과 필요한 자료를 직접 제작하여 활용하는 ICT 능력이 필요하며, 복잡한 조건과 논리연산 활용 등 논리적 사고 요소를 이해하고 잘 활용될 수 있도록 교육될 필요가 있다.
