In this study, a learning-teaching model enhancing the students to ask questions was developed and the influence of its application to the lesson of 'Chemical Change and Elements' of the 8th grade was investigated. This learning-teaching model was constructed initially by completing the work-sheet to activate student's question-asking, then by writing down their questions or uncertainties in the class, and finally with the feedback of student's question to the individual and to the class. Treatment and control groups (2 classes each) were selected from a girls' middle school in Seoul. and taught for 12 class hours during 4 weeks for this study. Before instruction, the test of attitudes toward science lessons and the test of adoption of scientific attitudes were administered, and the science scores of the previous course were obtained for the covariate. After instruction, the conception test. the achievement test, the test of attitudes toward science lessons, and the test of adoption of scientific attitudes were administered. The TOSRA (Test of Science-Related Attitudes) was used both for the test of attitudes toward science lessons and for the test of adoption of scientific attitudes. The study revealed that the treatment group showed significant differences from the control group in the scores of the conception test (p<.01) and of the achievement test (p<.05). But in attitudes toward science lessons and adoption of scientific attitudes. there were not significant differences between the two groups, even though the scores of the treatment group were a little higher than those of the control group. Educational implications of the effect of science teaching on the questioning activity of students are also discussed.
