Abstract

In this study, We made Computing Stories as a part of the new method of SW education. Also, we have developed unplugged activities using coding stories. We analyzed changes in learning motivation and academic achievement in the core concepts of CT by applying classes to elementary school students. For the development of coding stories, we conducted a questionnaire analysis of 11 expert groups to derive the core concepts of computational Thinking. Using the core concept of Computational Thinking, we developed a coding stories and unplugged activities linked with coding stories. It was confirmed that the score of the core concept of CT before and after class increased from 54.44 to 83.10 and the learning motive was also improved from the average score of 103.48 to 110.44. The results showed that the Coding Stories were effective in the students' Computational thinking achievement and SW learning motives.

본 연구에서는 SW교육의 새로운 방법의 일환으로 컴퓨팅 사고력 핵심 개념을 포함한 코딩 동화 및 코딩 동화 연계 언플러그드 활동을 개발하였으며 초등학생을 대상으로 수업을 적용하여 학습 동기 및 CT 핵심 개념 학업 성취도의 변화를 분석하였다. 코딩 동화 개발을 위해 전문가 집단 11인의 설문 조사 분석을 통해 컴퓨팅 사고력의 핵심 개념을 도출하여 타당성을 검증받았으며 도출된 컴퓨팅 사고력 핵심 개념을 활용하여 연구자가 직접 코딩 동화를 개발하였다. 코딩 동화 연계 언플러그드 활동 또한 연구자가 내용을 구성하였으며 수업 전, 후 컴퓨팅 사고력과 학습 동기의 변화 결과를 분석하였다. 수업 전, 후 컴퓨팅 사고력의 핵심 개념 학업 성취도 점수가 평균 54.44에서 83.10점으로 상승하였으며 학습 동기 또한 평균 점수 103.48에서 110.44로 향상되었다. 이를 통해 코딩 동화를 통한 SW학습이 학생들의 컴퓨팅 사고력 및 SW 학습 동기 증진에 효과적이라는 결과를 얻을 수 있었다.
