Abstract

The purpose of this study is to verify the effectiveness of the Development-oriented model (Discovery-Design-Development: DDD) for developing students' Computational Thinking skills in software education. DDD is a class model that learns the process of developing SW to solve real-life problems through three stages of Discovery, Design, and Development. In order to verify the effectiveness of the DDD, first grade students at G university who did not have SW education class were tested. As a result, the students who experienced SW development through DDD maintained the learning motivation of SW education before and after, especially the confidence area increased significantly. In addition, students also noted that the Design phase was particularly helpful in improving CT abilities and the DDD was a significant help in understanding of decomposition and algorithms.

본 연구의 목적은 소프트웨어 교육에서 학습자들의 컴퓨팅 사고력을 신장시키기 위한 개발 중심 모형(Discovery-Design-Development: DDD)의 효과를 검증하는 것이다. 개발 중심 모형은 탐구, 설계, 구현의 3단계를 거쳐 실생활 문제를 해결하기 위한 SW를 개발하는 과정을 학습하는 수업모형이다. 이러한 개발 중심 모형의 효과를 검증하기 위해 SW 교육 수업 경험이 없는 초급 수준의 G 대학교 1학년 학생을 대상으로 실험하였다. 그 결과 개발 중심 모형을 통해 SW 개발을 경험한 학생들의 SW 교육에 대한 학습 동기는 사전-사후 간 유지되었으며 특히 자신감 영역은 유의미하게 높아졌다. 또한, 학생들은 특히 설계(Design) 단계가 CT 능력 향상에 도움이 되었으며 개발 중심 모형은 문제분해와 알고리즘의 개념 이해에 상당한 도움이 된다고 응답하였다.
