This study lays its purpose on examining the effects of lessons with the application of drawing tasks on changes in conception among gifted science students. The lesson with the application of drawing tasks means the lesson where students express key concepts regarding lesson subjects in drawings which are then applied to the lessons to develop conception among the learners. This study analyzed the effectiveness of lessons by comparing conception scores before and after experiments between an experiment group with the application of drawing tasks and a control group with normal lessons for the gifted in general for 8 months from March to October, 2008. In addition, the researcher examined how the effectiveness of the developed lessons show differently according to levels of meta-cognition, creative problem-solving abilities, and scientific inquiry skills among the gifted students. The results from this study are as the following. First, lessons with the application of drawing tasks were effective in changing conception among the gifted science students. It is possibly because in the process where one student compare his/her own drawings with the others' ones and discuss them, changes in conception occurred effectively among the learners. Second, it was revealed that lessons utilizing drawing tasks have equal effects on changes in conception among both student groups irrespective of their levels of meta-cognition. Accordingly the lesson for changing perceptions utilizing drawing tasks developed in this study is a program which can be applied to all gifted science students in order to change conception among them. Third, lessons utilizing drawing tasks have the greatest effects on the gifted science students at a 'middle' level of creative problem solving abilities. Fourth, lessons utilizing drawing tasks have the greatest effects on the gifted science students at a 'middle' level of scientific inquiry skills. Putting these results together, it is thought that if lessons utilizing drawing tasks are applied to gifted science students, not only their concepts would be changed effectively but also their attitudes toward science would be changed positively.

The purposes of this study were to develop a learner activity-centered science class program, apply it to the fourth-grade elementary students, and analyze its effects on their attitude towards science, academic achievement, and concept sustainability. To this end, the content of the fourth-grade elementary subject related to 'volcanoes and earthquakes' was reorganized through 12 periods, and the class was divided into two groups. Then, general science class was applied to the comparative group, and the learner activity-centered science class program including writing, making, and expressing was applied to the experimental group. In order to compare the two groups regarding attitude towards science, academic achievement, and concept sustainability before and after the application, mind map data was collected and analyzed based on mind map grading criteria. As a result of the post-test, the two groups showed statistically significant differences in all the sub-factors of attitude towards science, that is, recognition, ability, value, and interest sustainability, especially in interest sustainability. As for academic achievement, as a result of the post-achievement test, the experimental group had higher average scores than the comparative group, and it also showed improved scores compared to the pre-achievement test results. In addition, as a result of the post-achievement test, both the two groups showed statistically significant results. In the concept sustainability test after the post-achievement test, the experimental group had higher average scores than the comparative group in the areas of center circle, branches, and expression, which were the evaluation criteria for the mind map analysis, and the two groups showed statistically significant differences in the areas of center circle and expression, except for branches. In conclusion, learner activity-centered science class turned out to be effective on students' attitude towards science, academic achievement, and concept sustainability. If the learner activity-centered science class program is actively introduced and used in actual educational sites, it is expected to contribute to improving related classes.

The purpose of this study was to apply After-school programs related to sub-chapter 'The Change of Weather', and thereby to investigate the effect of After-school program on science-related attitude and learning achievement of students, and interaction between treatment methods and students' learning ability. The subjects of study consisted of 2nd grade students of sixty four students in high school. Sixty four students were divided into two categories by experimental and control groups on the basis of midterm examination before teaching treatment. The experimental groups have received four After-school programs including making models of a weather front, measurement of wind, measurement of temperature and the dew point, making a three-dimensional weather chart which were developed by researcher for six times. The control groups have received the instruction through the conventional teaching methods. Seventy questions within seven frameworks of TOSRA have been used in this study as an evaluation instrument of science-related attitude. Learning achievement has been evaluated using an instrument developed by researcher. The scores of both pre-test and post-test were estimated by ANCOVA. The results of this study can be summarized as follows. (1) After-school programs were more effective in progressing the three categories of science related attitude of high school students i.e. pleasure of science class(p<.05), reception of scientific attitude(p<.01), attitude about a science research(p<.05) than conventional teaching methods. (2) Experimental groups showed statistically significant improvement on learning achievement than control groups(p<.05). (3) The effect of treatment methods on students' learning ability has been improved in experimental groups more positively than control groups(p<.05). High level students in experimental groups showed significant improvement on learning achievement than low level students according to the representing profile plot. But there were no significant interaction between treatment methods and students' learning ability(p>.05) In conclusion, the After-school programs have positive effect on the improvement of science related attitude and learning achievement.
