In this study, we investigated the influences of the role-playing analogy in chemistry concept learning on mapping understanding and mapping errors by analogical reasoning ability level. Seventh-graders (N=151) at a middle school were assigned to the comparison group and the experimental group. The students of the experimental group were taught with the 'running in the circle' role-playing analogy. After the students were taught about 'the relation between volume and pressure of gas', the test of mapping understanding in the next class and the retention test four weeks later were administered. The students with typical mapping errors were also interviewed to investigate their mapping processes. The results revealed that the role-playing analogy in chemistry concept learning improved mapping understanding and its retention regardless of analogical reasoning ability level. It was also found that the students in the experimental group had fewer mapping errors than those in the comparison group. However, there were similar patterns of mapping errors in both groups, and there were no significant differences in the frequencies of each type of mapping errors by analogical reasoning ability level. Educational implication of these findings are discussed.

Objective: This study aimed to analyze the changes and predictive factors of mothers' parenting competencies during their children's second to third grades in primary school. Methods: We used the data from the Panel study of Korean Parental Educational Involvement. We classified 373 mothers into three groups, 'reduced' parenting competency, 'maintained' parenting competency, and 'increased' parenting competency, and conducted one-way variance analysis and multinomial logistic regression analysis. Results: First, the mothers' parenting competency decreased between their children's 2nd year and 3rd year in primary school. Second, the 'reduced', 'maintained', and 'increased' groups differed from each other in the degree of change in self-system competency, level of understanding of school life, number of counseling sessions with homeroom teachers, and social networking. Third, the degree of change in self-system competency and social networking predicted the increase in mothers' parenting competency. The degree of change in self-system competency and the level of understanding of school life predicted the maintenance of mothers' parenting competency. Conclusion/Implications: This study, for the first time, has revealed the change in mothers' parenting competency and its predictive factors after the second year in primary school. How to support the growth of mothers' parenting competency was also discussed.

In computer education area, abstract thinking has played a positive role in programming ability, and language experience has also affected the ability. However, most of the studies were empirical. The practical research about the relation analysis between abstract thinking and programming ability has rarely been performed. Among various types of programming abilities such as coding, debugging, and reading, this paper focused on program understanding. We analyzed the affection relation on program understanding and the interaction effect between abstract thinking level and language familiarity. We surveyed 376 high school students on their abstract thinking levels, language familiarity, academic achievement, and the program understanding abilities of C and Scratch. From the research, we knew that the abstract thinking level played an important role in understanding the iterative program for the male students. In addition, if the students had the experience on other programming languages before entering high schools, then there was an interaction effect between abstract thinking level and program language familiarity.

The purpose of this study is clarify consumer problem on the basis of understanding consumer behavior, that is, to make explicit the effect of economic levels and educational background upon consumer consciousness and consumption behavior. The data in this study is from a survey in 1973 by means of a questionnaire of the opinions of 200 housewives of Seoul. The ${\chi}^2$(Chi-Squire) was applied for the statistical analysis of the data and following results were found. Generally consumers lack understanding of economic matters and satisfactory consciousness on matters of consumption life. And there is significant difference among the class on several matters. That is, the lower economic level and educational background are, the lower the understanding of economic matters and consciousness of satisfaction are. So the consumer education must be carried out for lower class of economic level and educational background. And in the present awakening of salers and makers is needed for consumers.

This study was motivated by recognizing the weakness of teaching and learning about the concepts of statements in high school mathematics curriculum. To report the reality of students' understanding about statements, this study investigated the 33 first-year undergraduate students' understanding about the concepts of statements by giving them 22 statement problems. The problems were selected based on the conceptual framework including five types of statement concepts which are considered as the key ideas for understanding mathematical reasoning and proof in college level mathematics. The analysis of the participants' responses to the statement problems found that their understanding about the concepts of prepositions are very limited and extremely based on the instrumental understanding applying an appropriate remembered rule to the solution of a preposition problem without knowing why the rule works. The results from this study will give the information for effective teaching and learning of statements in college level mathematics, and give the direction for the future reforming the unite of statements in high school mathematics curriculum as well.

In this study, we investigated the effects of explicit instruction about nature of science by elementary school students' cognitive level. Participants were six classes, 187 sixth graders at elementary schools in Daegu. Three classes were assigned to control groups and the other classes to treatment groups. Control groups were provided normal instructions and treatment groups were provided instructions integrated with nature of science about chapter 'electromagnet' for 9 class periods. The results of this study were as follow. Both low-cognitive level students and high-cognitive level students in the treatment groups are improved in understanding about nature of science by the explicit instructions about nature of science. Especially, the high-cognitive level students had more improvement than the low-cognitive level students in understanding about nature of science by the explicit instructions about nature of science. There were no significant differences between the test scores of the two groups in the science interest sub-domain of the science-related affective domain. But, there were significant differences between the test scores of the two groups in curiosity and open-mindedness of the scientific attitudes sub-domain of the science-related affective domain.

The purpose of this study is find out the correlation of level of knowledge of pre-service elementary teacher with space perception ability on 'Earth and Space' of elementary science. During the second semester of 2013, for 15 weeks, the classes were conducted for 3 hours per week and we find out knowledge Understanding degree and select terms offered by 5th grade science courses 'The solar system and the stars', 'Earth and Moon', 'change of seasons' section and measured space perception ability degree of pre-service elementary school teacher with a questionnaire. We analyzed the correlation of understanding level of knowledge in the field of astronomy of pre-service elementary school teacher with space perception ability. The results of the study are presented as follows. First, pre-service elementary school teacher showed a low level of knowledge understanding as it goes the upper grades about upper concept in 'The solar system and the stars', 'Earth and Moon', 'change of seasons' section' of astronomy area of elementary science 'Earth and space sector'. The pre-service elementary school teachers needs to acquire knowledge of astronomy area in elementary school curriculum. Second, pre-service elementary school teacher showed that there are differences individually in 'finding solid body' of sub-element of space perception ability. This shows that 'finding solid body' factor is associated with space perception ability. Third, in the section of 'The earth and the Universe' for elementary education, 'Reflection' and 'Finding solid body' which are low-level components of space perception ability were verified that have a corelationship with general grades in the astronomy conception test.
