Abstract

This study analyzed the effect of an unplugged educational program which focuses on the algorithm execution time analysis on enhancing the computational thinking of the third grade students. An unplugged educational program was developed by following the procedures of the ADDIE model based on the result of the demand analysis conducted with 70 incumbent elementary school teachers and 120 third grade students. The developed program was applied to 24 third grade students for 36 classes in six days and a comparison was made through pre-post comparison tests with 24 students who were taught with a board game program for the same period of time. As a result, the unplugged education program which focuses on the algorithm execution time analysis is deemed to have positive effect on the computational thinking of the third grade students.

본 연구에서는 알고리즘의 수행시간 분석에 초점을 맞춘 언플러그드 방식의 교육이 초등학교 3학년 학생들의 컴퓨팅 사고력 향상에 미치는 효과를 분석해보았다. 현직 초등교사 70명과 초등학교 3학년 학생 120명을 대상으로 실시한 요구분석 결과를 바탕으로, ADDIE 모형의 절차에 따라 언플러그드 교육프로그램을 개발하였다. 개발한 교육프로그램으로 초등학교 3학년 학생 24명에게 총 6일 동안 36시간의 수업을 진행하였고, 같은 시간 동안 보드게임 교육을 받은 24명의 학생들과 사전 사후 비교 검사를 통해 효과를 분석하였다. 분석 결과, 알고리즘의 수행시간 분석에 초점을 맞춘 언플러그드 방식의 교육은 초등학교 3학년 학생들의 컴퓨팅 사고력에 긍정적인 효과를 미치는 것으로 확인되었다.
