Abstract

More and more universities are enforcing SW education for non-major undergraduates. However, they are experiencing difficulties in educating non-major students to understand computational thinking processes. In this paper, we did not use the mathematical operation problem to solve this problem. And we proposed a basic problem-solving process teaching method based on computational thinking using simple physical devices. In the proposed educational method, we teach a LED circuit using an Arduino board as an example. And it explains the problem-solving process with computational thinking. Through this, students learn core computational thinking processes such as abstraction, problem decomposition, pattern recognition and algorithms. By applying the proposed methodology, students can gain the concept and necessity of computational thinking processes without difficulty in understanding and analyzing the given problem.

비전공 학부생을 대상으로 SW 교육을 시행하는 대학들이 점차 늘어가고 있다. 그러나 비전공 학생들에게 컴퓨팅적 사고 과정을 교육하는 데 어려움들을 겪고 있다. 본 논문에서는 이러한 문제를 개선하기 위하여 수학적 연산 문제를 활용하지 않았다. 그리고 간단한 피지컬 교구를 활용한 컴퓨팅적 사고기반 기초 문제해결과정 교육방법을 제안하였다. 제안한 교육방법에서는 아두이노 보드를 사용한 LED 회로를 예로 들어 교육한다. 그리고 컴퓨팅적 사고에 의한 문제해결과정을 설명한다. 이를 통해, 추상화, 문제 분해, 패턴인식과 알고리즘이라는 핵심 컴퓨팅적 사고과정을 학습한다. 제안한 교육방법을 적용하면, 학생들이 주어진 문제를 이해하고 분석하는 데 어려움 없이 컴퓨팅적 사고과정의 개념과 필요성을 습득하는 성과를 얻을 수 있다.
