Effects of Role-Play Method Related to the Global Warming and Ecosystem on High School Students' Knowledge Achievement as well as the Attitude towards Environment

역할극을 활용한 지구 온난화와 생태계 변화에 관한 수업이 고등학생들의 학업 성취도와 환경적 태도에 미치는 효과

In this research, we have carried out an experiment with grade 10 students. Students will be choosing their roles and creating their own script in relation to the environmental problems such as the seriousness of global wanning and the mutation of ecosystem. Throughout this process, they will come up with a solution to the problem In addition, we will assess students' knowledge achievement as well as the changes in attitudes toward environment, and analyze whether the role-play method of education is efficient or not. According to the research result, we have confirmed that the method of role-play as a education tool was more efficient than the traditional lecturing method. Students experienced higher rate of knowledge acquisition and more optimistic effects on their attitudes toward the mutation of ecosystem and also the seriousness of the global wanning. Students also pointed out in the interview that the role-play allowed them to share their thoughts with other classmates, which were not carried out frequently in the traditional education system In addition, each member of groups could participate cooperatively with teammates, which ultimately helped them to develop scientific and introspective ways of thinking.
