| Abstract: | Abstract The relative effectiveness of a problem-solving-based computer-assisted instruction (PSCAI) and a lecture-Internet-discussion instruction (LIDI) were compared for Taiwan senior high school students' science achievement and attitudes toward science. A pretest-posttest control group experimental design involving 8 classes was used. Experimental-group students (n = 156) received the PSCAI; comparison-group students (n = 138) received the LIDI. Instruments included the Earth Science Achievement Test (C. Y. Chang, 2000) and the Attitudes Toward Earth Science Inventory (C. Y. Chang & S. L. Mao, 1999). A multivariate analysis of covariance suggested that (a) students taught using the PSCAI scored higher but not significantly higher than did students in the LIDI group and (b) there were statistically significant differences in favor of the PSCAI on student attitudes toward the subject matter. |
