To produce highly creative students, engineering education must develop both problem recognition skills and the ability to solve problems independently. Chonnam National University has been developing a creativity program in which students identify and solve problems themselves. Initially, the primary focus was on solving problems, but this was unsuccessful at attracting the students' interest. To overcome this, we adopted Csikszentmihalyi's flow theory in our creativity program, much like the way this theory is used in computer games. As a result of adopting flow theory, we achieved our goal. Thus, in this paper, we will introduce Chonnam National University's creativity program (designed based on flow theory), which we will call the Self-Directed Creativity-Upgrade Program. Furthermore, we will discuss the impact of this program based on statistical analyses.

In this study, the effect of grouping by communication apprehension level in paired think-aloud problem solving was examined. Three classes of 9th graders (N=99) were randomly assigned to a control group, homogeneous group or heterogeneous group based on the test scores of their communication apprehension. After the instructions concerning ‘writing balanced chemical equation', ‘the law of conservation of mass', and ‘the law of definite proportions' for 7 class hours, students' chemistry problem solving ability and the perception to the paired think-aloud problem solving were examined. Two-way ANOVA results revealed that there was an interactive effect in the score of chemistry problem solving ability test. In simple effect test for the students of low communication apprehension, the scores of the heterogeneous group were found to be significantly higher than those of the control group. However, the students in homogeneous group had relatively positive perceptions to the paired think-aloud problem solving.

The purposes of this study were to examine the general tendency of knowledge and problem solving abilities of children to cope with climate change and to find out whether there is a difference in the ability to cope with climate change based on the gender and age of young children. For this purpose, 129 children aged 5 and 6 who are attended in day care center in Seoul and Gyeonggi area were selected. We used 10 questions to measure climate change response knowledge modified environment conservation knowledge checklist and used five problem solving situations to measure climate change response problem solving ability modified safety problem solving ability test item. The collected data were analyzed using mean, standard deviation, two-way ANOVA, and Pearson's correlation coefficient. As a result, 6-year-old children's knowledge of climate change response and ability to solve climate change problems was higher than that of 5-year-olds. There was no gender difference in knowledge of climate change response and ability to solve climate change. The higher the knowledge level of children's response to climate change, the higher their ability to solve climate change response problems. The results of this study confirmed the association between children's knowledge of climate change response and problem solving ability and showed that a more systematic curriculum for improving knowledge and problem solving ability for preventing climate change needs to be provided to children.

This study deals with the problem of transition from arithmetic to algebra and the relationship between elementary and secondary school mathematics for systems of linear equations. In elementary school, activity for solving word problems related to systems of linear equations in two variables falls broadly into using two strategies: Guess and check and making a table. In secondary school, those problems are solved algebraically, for example, by solving systems of equations using the technique of elimination. The analysis of mathematics textbooks shows that there is no link between strategies of elementary school mathematics and secondary school mathematics. We devised an alternative way to reinforce link between elementary and secondary school mathematics for systems of linear equations. Drawing a diagram can be introduced as a strategy solving word problems related to systems of linear equations in two variables in elementary school. Moreover it is closely related to the idea of the technique of elimination of secondary school mathematics. It may be a critical juncture of elementary-secondary school mathematics in the case of systems of linear equations in two variables.

Objective : The purposes of this study were two-fold; First it investigated self-esteem, stress and coping behaviors of mothers with handicapped children as a function of their and their children's characteristics; Second it examined the relationship among these variables. Method : The subjects were 294 mothers of handicapped children who were receiving treatment in one of the sixteen special therapy institutions in Seoul, Gyeonggi-do, and Gangwon-do. Rosenberg's(1965) Self-Esteem Scale translated by Jeon Byung-Jea(1974) was used to measure the degree of mothers' self-esteem. Mothers' stress was assessed using the Support Burden Scale revised by Seong Jong-sook(2000) and their coping behavior was examined using Folkman's(1986) Coping Scale translated by Jeon Sung-hye. The data were analyzed with descriptive statistics, t-test, one-way ANOVA and Pearson's Correlation. Result : The major results of this study were as follows; First, working mothers of handicapped children showed higher self-esteem and problem solving coping behavior more than non-working mothers. Self-esteem was found higher with high-income mothers than with low-income ones. Stress was shown more intense to low- and middle-income mothers than to high-income ones. Problem solving coping behavior was preferred more by high-and middle-income mothers than by low-income ones. Second, mothers with the mild-handicap children showed higher self-esteem than those with the first-degree handicap ones. Mothers of children with first-, second- and third-degree handicap perceived more stress than those with mild handicap. Coping behavior was significantly different depending on the severity of children's handicap, but no significant difference was found among the groups. Third, the higher the self-esteem of mothers was, the less they perceived stress and used more of problem solving coping behavior. When mothers perceived a great deal of stress, they used more of emotion-oriented coping behaviors.

The Purpose of this study is to investigate and suggest a counseling strategy and practice for solving interpersonal problems of elementary school students that elementary school teachers are now confronted with. In this study, first of all, the actual conditions of interpersonal problems of elementary school students were examined focusing on interpersonal aggressions(violence and victim). The features and problems of existing approaches for solving interpersonal problems of elementary school students were indicated. Although existing approaches for solving interpersonal aggression problems took temporary and external changes, they failed to notice psychological hurts that victims and aggressive victims got. As a fundamental and systematic way for overcoming problems of existing approaches, forgiveness counseling education based on empirical-scientific forgiveness researches was discussed. The Purpose of forgiveness counseling education is to make victims(aggressive victims) overcome the negative responses derived from interpersonal conflict(hurts and victims) and to facilitate them to response positively through experiencing forgiveness psychological process. Lastly, necessary assignments and topics to use forgiveness counseling education as an effective personality education approach were discussed.

There exist many differences between new Informatics curriculum and the current Computer curriculum. Since the new curriculum introduces new section of "Problem-solving methods and procedures" which are not included in current computer curriculum, it is required to define and specify objectives and content units of "problem solving methods" and "programming" topics for the new section. In this paper, we define and specify the objectives and detailed contents by surveying various computer curriculums used in many other countries. Then, the specified objectives and content units are validated by a group of computer education experts. The final results of specified objectives show that areas of "comprehension", "application" and "synthesis" take relatively high percentage over the other areas. In the content specification, we set the content structure by describing how to solve a given real-world problem with a non-computerized way, followed by representing or transforming it with a corresponding computerized model.

Problem solving ability can be fostered by dealing with many different types of problems. We investigated how $5^{th}$ and $6^{th}$ graders who did not learn traditional algebraic methods might approach the word problems of simultaneous equations. This result reveals that the strategy of guess-and-check serves as a basis for elementary school students in solving simultaneous equations. A noticeable remark is that students used the guess-and-check strategy in various ways. Whereas some students changed a variable given in the problem step by step, others did in a sophisticated way focusing on the relation between two variables. Moreover, some students were able to write an equation which was not typical but meaningful and correct. This paper emphasizes the need of connections between pre-algebraic and algebraic solutions.

The purpose of this study is to examine the effects of mathematical modeling activities on mathematical problem solving abilities and mathematical dispositions in elementary school students. For this study, we administered mathematical modeling activities to fifth graders, which consisted of 8 topics taught over 16 classes. In the results of this study, mathematical modeling activities were statistically proven to be more effective in improving mathematical problem solving abilities and mathematical dispositions compared to traditional textbook-centered lessons. Also, it was found that mathematical modeling activities promoted student's mathematical thinking such as communication, reasoning, reflective thinking and critical thinking. It is a way to raise the formation of desirable mathematical dispositions by actively participating in modeling activities. It is proved that mathematical modeling activities quantitatively and qualitatively affect elementary school students's mathematical learning. Therefore, Educators may recognize the applicability of mathematical modeling on elementary school, and consider changing elementary teaching-learning methods and environment.
