고등학교 화학 수업에서 CAI의 효과성 연구 - 화학 평형 단원을 대상으로 - = The Effects of CAI on Achievement and Attitudes in High School Chemistry in Chemical Equilibrium

다국어 초록 (Multilingual Abstract)

In this study, the multimedia CAI program for chemical equilibrium in high school grade 3 was developed and the effect of CAI on achievement and attitude toward chemistry instruction and computer was investigated. Before instruction, the test of attitudes toward chemistry instruction and computer were administered, and the grade in the mid-term examination was obtained. These scores were used as covariates. Mid-term science score was used as blocking variable. For chemical equilibrium instruction, traditional and computer assisted instruction were used. After instruction, the achievement test and the test of attitudes toward science instruction and computer were administered. The results indicated that students in the treatment group achieved significantly better than those in the control group, but did not show improvement of attitude to chemistry instruction and computer compared to those in the control group. No significant interaction between the treatment and the level of students` prior achievement was found. Female achieved significantly better under CAI than under traditional instruction. In two subtests(understanding and application), treatment group achieved better in the subtest of application than control group. CAI had an effect on chemical equilibrium state (about reversibility) significantly. While female of the treatment group did not show more positive attitude toward both chemistry instruction and computer significantly than that of the control group, male showed more positive attitude significantly. Educational implications are discussed.
