Abstract

The purpose of this study is to develop an effective teaching model for the "Problem solving methods and procedures" section in the revised academic high school informatics curriculum, verify its effectiveness, make the subject more effective and appealing to teachers as well as students. The model includes a middle school level informatics curriculum for the students who have yet to learn the section. This development follows the ADDIE model, and the Python programming language is adopted for the model. Using the model, classes were conducted with two groups: high school computer club students and undergraduate students majoring in computer education. Of the undergraduate students 75% responded positively to the model. This model was applied in the actual high school classroom teaching for 23 class-hours in the spring semester 2012. The Pearson correlation coefficient that verifies the correspondence between the PSI score and the informatics midterm exam grade is .247, which reflects a weak positive correlation. The result of the study showed that the developed teaching model is an effective tool in educating students about the "problem solving methods and procedures". The model is to be a cornerstone of teaching/learning plans for informatics at academic high school as well as training materials for pre-service teachers.

이 연구는 일반계고등학교 신 개정 정보 교육과정의 '문제 해결 방법과 절차' 영역의 효과적인 교수 학습을 위한 수업 모형을 개발하고 그것의 효과성을 검증하는데 목적이 있다. 중학교에서 이 영역을 학습하지 못한 일반계 고등학생들을 위해 중학교 교육과정을 포함할 필요가 있고, 학습자의 발달 단계에 알맞은 프로그래밍 언어를 채택하여 인지적 부담을 줄일 필요가 있다. 재미있게 프로그래밍 할 수 있는 퍼즐을 학습 예제로 사용할 필요가 있다. 연구 수행을 위한 연구 방법은 ADDIE 모형에 따라 수행한다. 수업 모형의 프로그래밍 언어로는 파이썬을 선택한다. 이 수업 모형의 효과성을 평가하고자 컴퓨터 부 학생들을 대상으로 수업을 진행하였고, 컴퓨터교육과 예비 교사들이 모의수업을 하였다. 예비교사의 75%가 수업 모형에 만족하였다. 2012년 3월부터 23시간동안 일반계고등학교 정보 교과 수업에 적용하였다. 수업 전 후에 문제해결력 향상 여부를 알아보기 위해 PSI 검사를 하고, 중간고사 정보 점수와 비교하여 약간의 정상관관계가 있다고 분석하였다. 따라서 개발한 수업 모형이 위 영역의 교수 학습에 효과가 있다고 분석한다. 그러므로 정보 교사들의 교수 학습 수업 모형의 지표가 되고, 예비 교사의 교육 자료로 활용하는 것을 제안한다.
