Different aspects of morality, namely, moral belief, moral judgement and moral behavior have been studied seperately. This study examined the development of these three aspects of morality in relation to internal attribution in one sample. A total of 371, third -and sixth- grade children from Masan city were responded to questionnaires on moral belief, moral judgement, and attibutional tendency. In addition, children's moral behavior was measured by the teachers' 5-item rating scale. As results, there were signigicant but low correlations among three components of morality. There were developmental differences in moral belief and moral judgement but there was no age difference in moral behavior. Compared to third graders, sixth graders were higher in moral judgement but lower in moral belief. Social experience as well as cognitive development on moral relativity could explain this paradoxical developmental trend in moral belief. There was a sex difference only on moral behavior : Girls were rated higher in moral behavior than boys. Internal attribution was significantly correlated with all three aspects of morality, .15 with moral belief, .45 with moral judgement, .14 with moral behavior, respectively. There was a significant developmental difference but no sex difference in attributional tendency: Sixth graders reported higher internal attribution than third graders. However, there was no developmental difference in correlations among internal attribution and three aspects of morality. Most importantly, internal attribution explained morality better than either age -or sex- variable. It was suggested that educational programs on morality need to focus on the internalization of it.

This study reviews the current status of Korean first graders, their experience with early care and education (ECE) programs, and their participation in private and after-school education. The research also examines how school adjustment during the first grade is related to family income, types of ECE programs, and participation in private and after-school education. Using the first year data of the Korean Child and Youth Panel Survey (KCYPS) 2010, this study analyzes 752 first graders who attended only one of two types of ECE programs (child care centers or kindergartens), after which two 25% income extremes were examined. The analysis demonstrates that children from low-income households attended child care centers more often, while children from high-income households attended kindergartens more often. For both low-income and high-income groups, child care centers had a lower starting age and longer attendance periods than did kindergartens. High-income household children started attending ECE programs earlier, experienced more private and after-school education, and received a larger number of private and after-school educational lessons. For the second research purpose, children from low-income families showed better peer relations in school adjustment, while children attending child care centers showed better teacher relations than children attending kindergartens. Children with after-school education also exhibited better peer relations. These findings show the importance of government support for early learning, especially for low-income families and offer a foundation for developing private education polices for early childhood before and after school entry.

This study was done to provide basic information for nutrition education and meal planning by analyzing children's food preference. For this purpose, 938 children from eleven elementary schools under meal service were randomly selected in Taejon. The survey was conducted by questionnaires, and data were analyzed by SAS program. Children prefered ssalbap to japkogbap and liked kimbap the best among one dish foods. But their most favorite foods were chajangmyun in noodles, miyeokkuk in soups, and chamchichigae in pot stew. Sixth graders like kimchichigae more than third graders. In the case of chims, children like duejigalbichim, sogalbichim, and dalgyalchim. In the jorim, they prefered duejigogi jangjorim, mechurial jangjorim to any other jorims. The preference of bockum, namul, jangachi, and jotgal is generally low. Children's preference is high in fruit, drink, fried food, one dish food and is low in jangachi, namul, bockum. These results suggest that the preference of foods should be fully taken into consideration in school meal service so that they can eat foods with pleasure. Foods, which are low in preference due to the cooking method, should be prepared with new cooking methods developed specifically for children. 'Even though the preference of food is low to the children, the nutritious foods should be utilized in the school menu. Then, the importance of food intake must be taught to them through nutrition education.

The purpose of this study is to analyze 3rd, 4th and 5th graders' probability understanding and raise issues concerning instructional methods and search for the possibility of learning probability. For the purpose, a descriptive study through pencil-and-paper test regarding fairness, sample space, probability of event, probability comparison, independence and conditional probability was conducted. The following conclusions were drawn from the results obtained in this study. First, the 3rd, 4th, and 5th grade students scored the highest in the sample space questions. In descending order of skill, the students scored the highest in sample space following probability of events, fairness and probability comparison. Second, however, the level of independence understanding was low. There was no meaningful differences between grades and the conditional probability was the least understood. The independence is difficult to develop naturally according to cognitive development. The conditional probability recognizing the probability of an event changes in non-replacement situations was very difficult for these students. Third, there were significant differences between the 5th graders and the 3rd and 4th graders in the probability comparison questions. It shows that 5th graders understand the concept of proportion when they compare equal ratio probability of an event. The 3rd graers could do different ratio probability of an event more easily than equal ratio probability of an event after they were instructed on probability comparison.

The purpose of this study is (a) to identify physical and content elements of children's books that seem to interest second and fifth graders to read, and (b) to observe how the influence of those elements on children's reading interest shifts as children develop. For the purpose of this study, children's books are classified into two groups: 'books of low preference' and 'books of high preference' as determined by second graders, and fifth graders' library circulation record in the library chosen as the sample for the present study. The physical and content elements of the books belonging to these two groups are analyzed and compared. Main findings and conclusions made in this study are summarised as follows: (1) The physical elements of children's books which have significant relationship with second graders' reading preference are illustration quantity, size of types, space between lines, and size of the book. (2) The content elements of children's books which have significant relationship with second graders' reading preference are the readability level of sentences, and the sex of heroes. (3) The physical elements of children's books which have significant relationship with fifth graders' reading preference are illustration quantity, illustration styles, and size of the book. (4) The content elements of children's books which have significant relationship with fifth graders' reading preference are the readability level, the sex of heroes, subject matters, themes and the environmental settings as the background of stories. (5) Reading preference of the pupils at the second and fifth grades are influenced by the quantity of illustration. Second grade pupils prefer reading books which contain a larger quantity of illustrations, whereas 5th grade pupils prefer books which contain less quantity of illustrations. (6) The relationship between second graders' reading preference and the illustration style are rejected at the $10\%$ significance level. A strong relationship, however, appears to exist between 5th graders' reading preference and the illustration style. The 5th grade pupils prefer more realistic illustrations, while cartoons and semi-abstract drawings do not appeal to them. (7) The type size, and space between lines which have had great influence on the book preference of 2nd grade pupils influence little on the 5th grade pupils book preference. (8) Second grade pupils prefer the book of a small Size, whereas 5th grade pupils whose reading taste has developed at a primary stage prefer the book of a large size beyond a certain standard. (9) Second grade pupils prefer reading books which can be easily read, whreeas 5th grade pupils prefer reading books containing difficult sentences. (10) Second grade pupils and the 5th grade pupils both prefer books in accordance with the sex of there heroes. (11) Relationship between second graders' reading preference and the subject matters are rejected at the 10% significance level. A strong relationship, however, appears to exist between 5th graders' reading preference and the subject matter. Fifth grade pupils prefer reading books of which the themes are mystery, exploration and adventure. (12) The theme of books is not proved to relate with the book preference of the 2nd grade pupils, but it is closely related with the book preference of 5th grade pupils. Fifth grade pupils prefer reading books which contain exploratory stories. (13) Second grade pupils are not influenced by the environmental setting of the story, but 5th grade pupils prefer reading stories with the environmental setting in the air. (14) The quantity of illustrations is the element influencing most on .the book preference of the 2nd grade pupils, followed by the space between the lines, which influences least on the book preference of the 5th grade pupils. (15) The physical element influencing most on the book preference of the 2nd grade pupils is the quantity of the illustrations. The physical element which has the most strong influence on the book preference of the 5th graders is illustration styles. (16) The content elements which has much influence on the book preference of the 5th grade pupils are certain kinds of characteristics of heroes. In case of the 2nd grade pupils book preference, striking evidence of such characteristics of heroes is not traced.

The purpose of this study is to analyze whether the required cognitive levels of the current 6th graders' science textbooks conform to the children's cognitive levels and to examine the students' sensed psychological difficulty of the current science textbooks. The eighty five students (boy: 39, girl: 46) from one elementary school were participated in this study. The results of the study are as follows. First, the 2/3 out of the contents in the six graders' science textbooks require concrete level of operation and the 1/3 out of the contents in the textbooks requires the formal level of operation. So the 70% students at the concrete operational level are likely to undergo difficulties with the 1/3 contents in the textbooks. Second, the students' psychological difficulty on the science textbooks is relatively low (approximately two out of five points) and there is not any special pattern between the cognitive level of the textbooks and the students' psychological difficulty of the textbooks.

The purpose of this study was to develop the quality of the textbook and to find out reasonable selection and structure by examining and analyzing the cognition of teacher and students on the structure and contents of elementary science textbook in the 7th curriculum. The findings of this study were as follows: First, as a result of the students’ cognition, their interest level of the learning contents was high and the degree of the difficulty of the learning contents was low on the whole. Second, as a result of the teachers’ cognition of contents of the textbook, teachers who taught third graders understood that the third graders have relatively much contents to be studied and the level of the contents of the textbook was high. On the other hand, fourth graders’ teachers recognized that contents to be studied and the level of the contents were appropriate. And they understood that there were much work to be studied in the units which were difficult and there were difference between contents to be studied and the degree of the difficulty in some units such as life or the earth fold. Third, as a result of the teachers' cognition of structure of the textbook. teachers were very affirmative to reduce school hours. They understood that current numbers and scale of the unit were appropriate. Teachers were satisfied with the structure of elementary science textbook in the 7th curriculum on the whole.

One of the prime objectives of school science is to help the children learn science concepts and conceptual schemes that will help them understand and interpret their environment. One of the basic scientific concepts is 'Change -everything existing in universe is changing always'. The purpose of this study was to investigate the characteristics of elementary and secondary students' conception of change. The subjects for this study were 489 students in Korea; 111 fourth graders, 95 sixth graders, 140 seventh graders and 143 ninth graders. Four items - mountain, river, ground, sea -were used for investigating students conception of change because representing the nature world in elementary and secondary level. The subjects were asked to check whether each item was changing and to explain each their check. Students' explanations were classified by whether they were sound understanding geologically, or not. The rate of responses that each item was changing was compared by grades and the rate of geological explanations was also compared by grades. Because students' conceptions of change might were effected by time scale, the additional questions that asked students whether the present status of four items were equivalent to the that of several points of time. As a result, the rate of scientific answers and patterns of explanations were similar by grade and the rate of geological understandings was relatively low. The frequencies of concept of change were more dropped as the point of time was closer to present.
