Abstract

The purpose of this study is to investigate the effect of students' formation of evolutionary concept and learning on the development of digital teaching materials. The explanation of biological evolution, which explains the changes that living organisms undergo over a long period of time, can provide various contents for use in a book. The production and editing of images in digital textbooks would provide explanation of difficult concepts in a fun way. For this study, we designed instructional materials consisting of four class hours using iBooks Author, an electronic book authoring tool based on the 5E learning cycle model. In order to verify the effectiveness of the developed digital textbooks, we compared instructions by the general textbooks to those using digital textbooks. Both teaching through general textbook form and teaching using digital textbook materials had a significant effect on the formation of the concept of evolution, but interest in biological science and evolution increased significantly only in the group taught using digital textbooks. As a result of testing the instruction effect by the digital textbooks by classifying the students by type, the group that is familiar with smart devices was more active and interesting in class depending on digital literacy. The satisfaction of the developed digital textbooks also showed a positive score in the group with high digital literacy. The results of this study suggest that the development of digital textbooks in the unit of evolution can be an instructional material for easy and interesting approach to difficult concepts in the teaching of evolution.

이 연구는 중학교 '진화' 단원을 디지털 교재로 개발하여 학생들의 진화 개념 형성과 학습에 대한 흥미에 효과가 있는지 알아보고자 하였다. 오랜 시간에 의한 생물의 변화를 설명하는 생물 진화에 대한 설명은, 많은 내용을 다양하게 제공할 수 있고, 영상을 제작하고 편집할 수 있으며, 어려운 개념을 재미있게 제공할 수 있는 디지털 교과서가 서책형 교과서를 통해 이루어질 때 효과적일 수 있다. 연구를 위해 먼저 5E 순환학습 모형을 기반으로 전자책 저작 도구인 iBooks Author를 활용하여, 4차시로 구성된 진화수업을 만들었다. 개발한 디지털 교재의 효과 검증을 위해 서책형 수업과 디지털 교과서를 활용한 수업을 비교했다. 서책형 교재를 통한 수업과 디지털 교재를 활용한 수업 모두 진화 개념 형성에 유의미한 효과를 보였으나 생명 과학 흥미도와 진화 흥미도는 디지털 교재 수업 집단에서만 유의미하게 증가하였다. 또한 학생을 유형별로 나누어 디지털 교과서 효과를 확인한 결과 디지털 리터러시에 따라 스마트 기기에 친숙한 그룹이 수업에 더 적극적이었고 흥미가 높았다. 개발된 디지털 교재의 만족도 역시 디지털 리터러시가 높은 그룹에서 긍정적인 점수를 나타냈다. 이 연구 결과는 진화 영역 디지털 교재 개발은 어려운 진화 개념을 쉽고 재미있게 접근할 수 있는 수업 도구가 될 수 있음을 알려준다.
