광합성에 영향을 미치는 환경요인 실험을 위한 시뮬레이션형 코스웨어의 적용

Abstract

The purpose of this study was to test learning effect of the developed simulation courseware for the experiment on environmental factors affecting the rate of photosynthesis. Non-equivalent pretest-posttest control group design was used in this study. Among 128 seventh grade students who were selected, 63 students had virtual experimental lesson and 65 students had real experimental lesson and 54 eighth grade students were selected for the virtual experimental lesson. Comparing the estimated marginal mean by analyzing covariance which controls the results of pretest of achievement, revealed that the group of virtual experimental lessons showed higher achievement than the group of real experimental lessons in controlling variable. Furthermore, developed courseware was more effective to students who did not have previous learning experience about photosynthesis. This finding suggests that inductive approach is more effective for students to develope inquiry ability than the deductive approach.
