The purpose of this study was to analyze abductive reasoning on the inquiry of scientists and elementary school gifted children in science. Subjects for this study were eight scientists and eight elementary school gifted children in science studying in the Academy of Gifted Child Education in Science affiliated with Seoul National University of Education. As a result, abductive reasoning on the scientific inquiry of scientists and gifted children showed the three stages of generating hypotheses, designing the experiments, and interpreting the results. The abductive reasoning in each stage characterized the five types as complex abduction, analogical abduction, observation-based abduction, logic-based abduction, selective abduction. The sub-reasoning process of the abductive reasoning of gifted children in science differed in some ways from that of scientists. First, for most scientists, representing a method or representing a casual explican appeared after searching for the characteristics of variables but for gifted children in science, searching for the characteristics of variables appeared after representing a method. Second, scientists tend to rely on logic-based abduction but gifted children in science tend to rely on observationbased abduction. Third, scientists reason by the similar rate in three steps: generating the hypothesis, designing the experience, interpreting the results. On the other hand, most gifted children in science reason about designing the experience.

The purpose of this study was to examine the effects from social supports and global self-worth on stresses for the children. The subjects were 438 children of the 5th grade in Elementary School and the first grade in Junior High School in Taejeon. The instruments used for this study were Children's Social Support, Global Self-Worth and Stress Scale. The data were analyzed using t-test, Pearson's correlation, multiple regression and path analysis. The main results of the study were as follows; 1. The stresses were different depending on age. When the family and the teacher give higher social supports, the 5th graders have higher global self-worth. When the family gives higher social supports, the stresses were decreased for the 5th graders. When the children have higher global self-worth, the stresses were decreased. 2. When the first graders in Junior High School experienced higher global self-worth and social supports from their friends, family, teacher, the stresses were decreased. 3. The first graders in Junior High School experienced more stresses than the 5th graders in Elementary School in parent-related and academic-related domains. But the first graders in Junior High School experienced less stresses than the 5th graders in Elementary School in friend-related domains. 4. The path analysis showed that social supports from friends and family explained 15% of the stresses for the 5th graders in elementary school. Social support from friends, family, and teacher explained 28% of the stresses for the first graders in Junior High School. 5. For the 5th graders in Elementary School, social supports from friends and family had direct influences on the global self-worth. And the global self-worth had direct influence on children's stresses. But for the first graders in Junior High School, social supports from friends, family, and teacher had direct influences on the global self-worth. And the social supports from friends had direct and indirect effects on children's stresses. 6. For predicting the stresses, the most significant variable was the global self-worth for the 5th graders in Elementary School and the first graders in Junior High School.

This study aimed to investigate protective factors and risk factors in elementary students' life satisfaction. Participants were 2844 (1524 boys, 1320 girls) children who grades were 4th, 5th, 6th in KYPS (Korea Youth Panel Survey). Data mining decision tree model was performed with sex, appearance, delinquency, family income, attachment to parents, parental monitoring, attachment to teachers, academic achievement, peer delinquency, and attachments to peer. The results revealed that : (1) For 4th graders, academic achievement, attachment to parents, and appearance were significant predictors for life satisfaction. (2) For 5th graders, attachment to parents, academic achievement, parental monitoring and appearance were significant predictors for life satisfaction. (3) For 6th graders, attachment to parents, appearance, parental monitoring and delinquency were significant predictors for life satisfaction. Protective factors and risk factors were changed according to interactions between significant independent variables. These results suggest that children's diverse conditions should be considered individually in programs for children's life satisfaction.

The purpose of this study was to verify the validity and reliability for the Test of Oral Reading and Comprehension Skill (Gardner, 2000) for Korean lower level elementary school children. Subjects were 122 first to third grade students, tested individually. The vocabulary and comprehension sub-tests of K-WISC III and the reading comprehension test of Basic Academic Skills Assessment (Kim, 2000) were used to verify concurrent validity. Internal reliability was determined by internal consistency coefficients. Results verified concurrent validity. Test scores differed significantly by grade level. Test reliability was also confirmed. In conclusion, the Oral Reading and Comprehension Skill Test (Gardner, 2000) is reliable and valid for examination of reading comprehension skills for Korean lower level elementary school children.

A nutrition survey of 274 children, 6 to 12 years old, in the Nan Hyang elementary school, which offers no school lunch program and is situated in Shinllim 7-dong of Seoul, as the location of one of the socioeconomically vulnerable groups, was undertaken in July of 1989, to investigate nutritional status. anthropometric data of subjects surveyed slightly lower results than the Korean standards and further lower results than those of Yun Jung elementary school children of Youido, Seoul. 16.3% of subjects were proven to be anemic according to the hematocrit criterion established by the WHO. Mean urinary urea nitrogen/creatinine ration was 9.5$\pm$4.1. Family environment were positively correlated with anthropometric data and results of biochemical tests.

It is not too much to say that problem solving is still the focus of school mathematics though the trend of mathematics education for ten year from the one of 1980 is problem solving and the one of mathematics education for ten year from the one of 1990 is standards and constructivism. There are so many crucial clues or methods in good problem solving but I think that one of them is a representation. So, the purpose of this study is to investigate what is the meaning of representation in general and why representation is so important in elementary mathematics learning, Moreover, I have analyzed the gifted children's thinking of representation which is appeared in the previous internet home task of 40 gifted children who are selected through the examination of 1st, 2nd with paper and pencil and 3rd with practical skill and interview and finally I have presented some examples of children's representation how they use representation to model, investigate and understand special concept more easily in elementary school mathematics class.

In this study, a preliminary study has been made to check the availability of examination after selecting one among the criteria to adaptation of school life, in recognition of the necessity for a tool in order to collect multi =dimensional information about children. An examination has been done with the survey target of 291 pupils in the fifth and sixth grade in an elementary school located in Incheon. And the focus group with the teachers in charge of each class was undertaken to check the availability of the examination. As the result of the examination, 37 was the average score of children diagnosed as the category of temporary maladaptation in terms of the score of 4 sub-scales of school adaptation and their total scores, and 28 was the score which corresponds to the assessment of teachers. The results of examinations and the evaluations of teachers were proved to be highly correlated. Lastly discussion is focused on the meaning of these findings and the suggestions for the further studies.

The purposes of this study were to investigate children's preconception about matter, to analyze children's conceptual change. of ,matter by science learning activities, and to investigate understanding possibility about mallet The subjects of this study were the second grade students of an elementary school and science learning activities were conducted to 2 boys and 3 girls for investigating their conceptual change. Video tape recording, interview, drawing pictures and writing statements were used to collect data. The concepts in this study were properties of matter, states of matter, uses of matter and origins and changes in matter. Then, the collected data were analyzed by the way of categorization and qualitative method. The conclusions of this study are as follows: science loaming activities were effective for changing misconceptions of matter to scientific concepts. Conceptual changes of high achievers happened easier and more than of low achievers. In the ideas about matter, some children had supernatural ideas and animism, which were most second grade students' characteristics.
