The purposes of this study were to compare and analyze the local primary textbooks for the subject of 'We are the First Graders'. This study analyzed the common points and the differences among three textbooks developed by the three educational bureaus of Seoul, Daegu and Busan. The criterion of analysis were scope, sequence and integration of curriculum representing the principles for developing curriculum. The results were as follows: First, the scopes of topics included in 2007 National Curriculum of 'We are the First Graders' were faithfully reflected in the three local textbooks. Second, the sequences of textbooks were generally arranged according to the order of curriculum content except for some contents. As for 'Wise School Life', some contents were presented at the first unit of the three textbooks and the others were gradually expanded at the latter of the textbooks. Third, the integration of curriculum appeared meaningfully in the three textbooks. Based on these results, this study suggested some recommendations on the activites for the adaptation at the early stage in the primary school under 2009 National Curriculum.

The purpose of this study is to find out effective ways to take care of the 8th and 10th graders' disposition causing math. disliking. To accomplish this goal, we proceeded as follows : First we categorized the 11 factors recognized as the reasons of math. disliking into 4 math. disliking causes such as psychological f: environmental cause, conceptual cause, relational cause and application related cause. Second, to take care of these tow causes, we developed materials which are closely related with the contents of the 8th and 10th graders' school mathematics. Third with these materials we taught the students who had proved to have the math. disliking trend, for one semester. As a consequence of this experiment we arrived at the following results. As for psychological & environmental causes, 35.7% of the 8th graders and 17% of the 10th graders proved to have been improved significantly. This result shows that the curing of the psychological & environmental causes is more effective in the 8th graders than in the 10th graders. i.e., the curing effects of the students' psychological & environmental cause for disliking math. decline as they get older. As for conceptual causes, 35% of the 5th graders and 30% of the 10th graders proved to have been improved significantly. In case of the 8th graders this ratio was similar to that of the other causes. But as for the 10th graders this ratio was a little low compared with that of the case of relation causes and application related causes. As for relational causes, 35% of the 5th graders and 49% of the 10th graders proved to have been improved significantly. Especially the 10th graders improved greatly. Among the four factors that compose this cause, especially hierarchy and connection factors were effectively cured. On application related causes, 47% of the 5th graders and 57% of the 10th graders proved to have been cured significantly. And among the four types of causes listed above, this was the most successfully cured one. Of the two factors of this cause, the basic application factor appeared to have been improved in all experimental groups. In connection with teaching methods, we found out the followings two facts. First, the more teachers push students to solve their tasks with their own efforts, the higher is the ratio of owe. Second, the more teachers teach students personally, the more effective are the teaching results.

In this paper, we applied Sfard's reification theory to analyze the secondary students' level of conceptualization with regard to the formula of quadratic equation. Through the generation and development of mathematical concepts from a historical perspective, Sfard classified the formulation process into three stages of interiorization, condensation, and reification, and proposed levels of formulation. Based on this theory, we constructed a test tool reflecting the reversibility of the nature of manipulation of Piaget's theory as a criterion of content judgement in order to grasp students' conceptualization level of the formula of quadratic equation. By applying this tool, we analyzed the conceptualization level of the formula of quadratic equation of the $9^{th}$ and $10^{th}$ graders. The main results are as follows. First, approximately 45% of $9^{th}$ graders can not memorize the formula of quadratic equation, or even if they memorize, they do not have the ability of accurate calculation to apply for it. Second, high school curriculum requires for students to use the formula of the quadratic equation, but about 60% of $10^{th}$ graders have not reached at the level of reification that they can use the formula of quadratic equation. Third, as a result of imaginarily correcting the error of the previous concept, there was a change in the levels of $9^{th}$ graders, and there was no change in $10^{th}$ graders.

This study investigated whether Korean mothers' emotion socialization beliefs are related to emotional functioning in children differing across gender. We interviewed Korean mothers (N = 100) of first graders (55 boys; 45 girls) about their sensitivity, their reactions to children's distress, and children's emotion regulation. Two components of emotion regulation were distinguished: regulation and negativity. Results revealed that mothers' proactive sensitivity and their supportive reactions were related to their children's regulation, whereas unsupportive reactions were related to children's negativity. Child gender moderated the associations between mothers' socialization beliefs and children's emotion regulation: mothers' proactive sensitivity was more strongly associated with competent regulation in girls than in boys. Mothers' unsupportive reactions were related to increased negativity only in girls. Results are discussed from a cultural perspective, focusing on gender differences in the links between maternal socialization and children's emotional outcomes in Korea.

The purpose of this study is to investigate how $3^{rd}$ and $4^{th}$ grade elementary students view about 'Science story', which is recently inserted in the new version of science text books. For the study, four hundred $4^{th}$ graders at four schools were considered in the area of Cheonan city, Chungnam province. The degree of student's preference, preferable science topics from the 'Science story', the reason for their preference, and their attitudes toward general science were examined. The study was initiated after student's reading of the 'Science story' (Advanced science, Science in the life, Science in the history, and Future science directions). The student attitudes toward general science were examined using questionnaire survey prior to others. The results of the study are summarized: First, the students who have more interests and affirmative attitudes about science subjects with high scores are more favored about 'Science story'. Second, generally the students prefer reading topics in the order of 1) Science in the life, 2) Advanced science, 3) Science in the history, and 4) Future science directions. However the order was flexible depending on student's gender, preference, and attitudes. Third, the student's interests about 'Science story' was mostly raised from the new scientific topics in the book. And it was also raised partly from their personal interests and usefulness for science learning. Based on the results of our study, we included some suggestions for the improved 'Science story' and their utilizations.
