The purpose of this study is to find how elementary students who have different spatial ability affects their understandings on the concept of the rotation of the earth. In order to perform this study, four 5th grade students were picked out of 85 students in Seoul. They had the same conceptual achievement on the movement of celestial bodies but had different spatial abilities. The results of this study were as follows : Regardless of their spatial ability, they understand how day and night are performed, and understand the fact that diurnal motions of moon are related to the rotation of the earth. Also, the students who had higher spatial abilities showed better understanding on the concept of the rotation of the earth and understood the reconstructed concepts in stereoscopic space. But the students who had lower spatial abilities did not fully understand the concept of the rotation of the earth and just memorized them as fragmentary concepts. As for the gender differences, the boy students who had higher spatial ability explained the concept clearly and the others who had lower spatial ability had difficulty in understanding the rotation direction of the earth related with the diurnal movement of celestial bodies. In the same manner, the girl students who had higher spatial ability explained the concepts concretely and the others who had lower spatial ability had difficulty in explaining the concepts by operating them stereoscopically. Therefore, developing teaching methods and studying data and so on, for the girl students, they should be trained to operate the stereoscopic space directly, and for the boy students, they should learn to think over objects with multi-viewpoints. And then the spatial ability on the movement of celestial bodies would be expected to be improved.

The aim of this research is clarify the relationship between concept understanding degree about the environment and environmental sensitivity and heighten understanding of environmental education target to pre-service elementary teacher. The subjects of this study are science education intensive course 65 students of B educational university. Concept understanding degree about the environment was separately investigated by 'the definition of environmental education', 'Write The positive concept of the natural environment education and briefly describe.''The negative concept of the natural environment education and briefly describe'. Next clarify the relationship between concept understanding degree about the environment and environmental sensitivity target to pre-service elementary teacher. Based on these results, propose an alternative to cultivate pre-service elementary teacher's knowledge about environmental education. Degree of understanding of the concept environmental education research results are as follows. First, Cognition degree about definition of environmental education of pre-service elementary teacher is correctly recognized generally. Second, They do not think deeply about natural environment when it comes to the positive concept of the natural environment of pre-service elementary teacher. Third, They have only a little interest in natural environment when it comes to the negative concept of the natural environment of pre-service elementary teacher. Correlation research results of degree of understanding of the concept of environmental and environmental sensitivity are as follows. High understanding degree of environmental education is high environmental sensitivity. Heighten environmental sensitivity of pre-service elementary teacher will be sustainable environmental education so education is necessary for environmental Sensitivity training.

The purpose of this study was to verify the effects of science classes using abductive strategies on the scientific concept understanding and meta-cognition. The subjects included two classes of sixth graders from K Elementary School in B Metropolitan City and they divided into two groups. Research group was composed of 21 students(10 boys, 11 girls) and comparative group was composed of 21 students(11 boys, 10 girls). In order to achieve aims of this study, proper contents to apply abductive strategies were selected from the first semester science curriculum for sixth graders. Also five-steps study papers were designed to elicit abductive reasoning. While the research group received 20 times of reframed science lessons using abductive strategies, the comparative group received common science lessons according to the teachers' manual. The results of this study are as follows. First, science classes using abductive strategies were effective for the scientific concept understanding. Also there were statistically significant differences between the research group and the comparative group in overall science sub-domain. In the process of hypothesis formulating, students tried to find out scientific causes thoroughly to present the optimal explanation and they concentrated on the analysis of each scientific concept. It is thought that this process contributed to better understanding in scientific concepts. Second, science classes using abductive strategies were effective for improving meta-cognition. There were statistically significant differences between the two groups and especially in monitoring that is one of sub-factors of meta-cognition. It indicates that hypothesis formulating process gave positive effect on meta-cognition by stimulating critical thinking and manifesting elaboration.

This study compared and analyzed the chemistry curriculum of South Korea and Singapore. The analysis revealed that Korea's achievement standards in the chemistry subject comprised knowledge and skills, whereas Singapore's achievement standards comprised knowledge, skills, values, and attitudes. The scope of knowledge and skills of the Singaporean achievement standards-wherein each element was explicitly presented-were more extensive than that of Korea. The elementary school curriculum in both countries was structured to help students qualitatively understand materials in real life, whereas the middle school content was structured such that students could understand the topic of particles. Additionally, several differences were found in specific content elements; for example, the periodic tables were included only in the Singaporean content, whereas changes in the volume of gas according to temperature and pressure were included only in the Korean content. The Singaporean academic achievement standards, integrating knowledge, skills, values, and attitudes in science curriculum, can be used as a reference for adjusting and restructuring the Korean curriculum.
