This study examined the knowledge structure constructed by children before formal instruction, and successive changes in the structural complexity of knowledge during the learning of the 'Structure and Function of Plants' unit. The researchers let the 5th graders draw the first draft of their concept maps in order to examine the pre-existing knowledge structure concerned with the unit and also four concept maps after completing every fourth lesson. Each concept map drawn by children on the basis of the previous one showed the degree of their current understanding on the structure and function of plants. The results revealed that only two levels of hierarchy and five relationships among the components of the first concept map(relationship, hierarchy, cross link and example) were proven to be valid in terms of conceptual relevance. According to the standard map, there was no change in hierarchy from the 2nd to the 3rd map, and in example from the 2nd to the 4th map. However, the gradual and successive increases of the scores in all components appeared in the children's maps throughout the unit. Knowledge restructuring occurred strongly in the early periods from the 1st to the 6th lesson, and the significant stable changes in tuning and accretion appeared throughout the whole lessons. The results also showed that there were no significant gender differences on the 5th grader's knowledge structuring.

As the society has been capitalized, the importance of money has appeared widely. And there are many problems caused from the lack of money is supposed rather a qualitative problem happened by mismanagement of money than a quantitative. The purposes of this study are to suggest the desirable direction in money management education to adolescents and to provide some basic data to resolve the juvenile delin-quency caused from lack of money. With this purposes this study dealt with the money management behavior of adolescents with reference to self-concept, which was considered one of the influential factors to the money management behavior. Questionnaires composed with the Self-concept test (developed by Dr. chung) and the Money management test (developed by Dr. Troelstrup) were distributed to 300 high school students. 180 of them was taken as data. mean score and F-ratio were applied as statistical methods. As result, significant difference in money management behavior between the groups divided by self-concept scores were found. The higher the self-concept score is, the more desirable the money management behavior is. Here we cannclude as follow; As the money management behavior of adolescents differs with reference to the self-concept, it is possible to help the adolescents 세 develop the money management by inspiring the self-concept. And money management training as a consumer education is needed by all means at home, because it has an important effect upon the identity establishment, the major developmental task in adolescence.

The purpose of this study is to suggest effective teaching methods on the concept of infinity for students to obtain the right concept in the middle school curriculum. Many people have thought that infinity is something vouge and unapproachable. But, nowadays it is rather something with a precise definition that lies at the core of modern mathematics. To understand mathematics and science very well, it is necessary to comprehend the concept of infinity. But students tend to figure out the properties of infinite objects and limit concepts only through their experience closely related to finite process, and so they are apt to have their spontaneous intuition and misconception about it. Since most of them have cognitive obstacles in studying the infinite concepts and misconception, mathematics teachers need to help them overcome the obstacles and establish the right secondary intuition for the concepts through good examples and appropriate explanation. In this study, we consider the developing process of the concept of infinity in human history and give some comments and suggestions in teaching methods relative to that concept with new suitable examples.

Purpose: The purpose of this study was to investigate the effects of a small group collaboration learning program through MBTI on nursing professional self-concept and career maturity of nursing college students. Method: A randomized control pre-post test experimental research design was used. There were 30 sophomore nursing students in the experimental group and 30 in the control group randomly assigned and randomly selected from the nursing program of T University in Daegu, Korea. The program through MBTI was developed by Kwon (2002) using a program by Shim and Kim (1997) as treatment. The experimental group received the program through MBTI for 30 hours (2 times a week for 15 weeks) while the control group received no treatment except a series of tests. Measures were the MBTI test, nursing professional self-concept scale, and career maturity scale. The data were analyzed with SPSS Win 17.0 program, chi-square test, and t-test. Result: The experimental group which received the program through MBTI had a higher score of nursing professional self-concept and career maturity change than the control group. Conclusion: A small group collaboration learning program through MBTI was effective in increasing nursing professional self-concept and career maturity of nursing college students.

This study examines the scientific concept development of young children in terms of the day-night cycle. The subjects consisted of 180 three-, four-, and five-year-old children from two kindergartens and one children's center located in Seoul and Jeju. Individual interviews were conducted to collect verbal and pictorial responses on the day-night cycle. The scientific concepts on the day-night cycle are classified five stages including : no recognition, egocentric concept, initial mental models, synthetic mental models, and scientific mental models. Using two-way ANOVA, scores for the types of concept on the day-night cycles were then analyzed according to both the ages and genders of the children. The results reveal the existence of significant differences in terms of the types of concept of young children according to age. Most three-year-olds children had no recognition. Most three, four, and five-year-old children revealed egocentric concepts. Four-year-old children revealed that were in the initial stages of experiencing the mental models and synthetic mental models of the day-night cycle. Five-year-old children revealed that they were in the early stages of experiencing the initial, synthetic, scientific mental models of the day-night cycle. The results suggest appropriate ways of science education for young children based on the development of scientific concepts of the day-night cycle.
