In order to comprehend the internal processes of heterogeneous small-group cooperative learning in science class, this study investigated verbal interaction patterns by the achievement level. Frequency of verbal behaviors was compared in respect of the achievement level, and participation patterns and characteristics were investigated. Verbal interaction patterns by the achievement level were also analyzed based on students' perceptions of interactions. It was found that there were no significant frequency differences between high- and medium-achieving students' verbal behaviors. The verbal interaction patterns showed co-construction processes between high- and medium-achieving students, which was consistent with the students' perceptions of interactions. These suggested that medium-achieving students actively participated in small-group interactions in science class.

The purpose of this study is to find the programming capability for the students majoring in H/W. For implementing this purpose, first, the academic achievements on the C language and C++ language are measured for the graduates-to-be majoring in H/W and S/W. Second, the H/W and S/W curriculum are compared and analyzed to derive the relevant factors to give influence on the academic achievement of the programming. Third, to find the influence of mathematic competence on the academic achievement of the programming, the relevance is analyzed in terms of the regression analyses between mathematics curriculum and programing curriculum. This paper presents the effective teaching method for the improvement of the programming academic achievement in the H/W curriculum.

Purpose: The aim of this study was to evaluate the degree of achievement of anterior tooth movement using a thermoplastic clear aligner by superimposing pretreatment, setup, and post-treatment models and to analyze the factors that influence it. Materials and Methods: Forty patients who underwent clear aligner treatment at the Department of Orthodontics were included in the study. The pretreatment, setup, and post-treatment models were superimposed, and the achievement rates were evaluated. We analyzed the factors that caused changes in achievement rate on each condition. Result: The average achievement rate of total tooth movement was 57.65%. Mesiodistal and anteroposterior displacements were achieved better than vertical displacement and rotation. In each displacement, posterior, mesial, and extrusive movements were better achieved than the rotation. Spacing was better corrected than crowding, especially in the mesiodistal direction. Most of the tooth movements were achieved better when using 3-step thicknesses of aligners were used. Conclusion: The treatment results of clear aligners may differ depending on the type of tooth movement, age and other treatment conditions. Clinicians should consider unfavorable conditions based on the results of this study.

The purposes of this study are to investigate the school science high achievers' achievements in enrichment physics, logical thinking level, and to analyze the relationship between logical thinking level and the achievement in enrichment physics of high achievers in science. The subjects were 357th and 8th graders who achieved highly in school science. To assess their achievements in enrichment physics, we developed a new test consisting of descriptive problems which were based on middle school curriculum. Those problems require one or two steps of thinking process, not simple knowledge of science. To assess logical thinking level, we used the instrument called GALT(Group Assessment of Logical Thinking) developed by Roadranka et al. The results showed that the school science high achievers' average achievement in enrichment physics was low, 56.3 out of 150, which indicated that they had not done much of enrichment learning beyond middle school science curriculum. Just only 54% of the school science high achievers are in formal logical thinking level. From the analysis of relationship between their logical thinking level and the achievement in enrichment physics, the value of the correlation coefficient was 0.174, which means that they are not almost correlated. Therefore, it is not desirable to judge science gifted children just from achievement in school science or enrichment physics, so both(logical thinking and the achievement in enrichment physics) tests should be taken for selecting gifted student.

This study was to verify the structural relationships among achievement goal orientation, self-leadership and sport motivation of skating athletes. The data were collected out of skating athletes in Seoul and Gyonggi area, and total 369 copies of data were utilized in this study. To verify the relationships among achievement goal orientation, self-leadership and sport motivation, the construct validity and reliability for each factor were analyzed using SPSS18.0 and AMOS18.0 program. And the relationships among three factors were analyzed using covariance structural analysis. The results were as follows. First, the achievement goal orientation of skating athletes had positive effects on self-leadership. Second, the achievement goal orientation of skating athletes had positive effects on sport motivation. Third, the self-leadership of skating athletes had positive effects on sport motivation.

The purpose of this study was to investigate the effects of a teaching-learning program using the history of science on elementary school students' academic achievement, science attitude, and science process skill. Subjects were 72 students of two groups in the 5th Grade. A experimental group of 36 was instructed 10 lessons in unit of 'our body' using the history of science. The history of science materials used in this program included 4 explicit method, which are Eii, Eij, Eik and Ea type, and 1 implicit method which is I type. The contents validity of this program was reviewed by the science education specialists. The results of the study were as follows: Students of experimental group showed statistically more significant increase in academic achievement and science attitude than control group students. However, there was no significant difference on science process skill between the instruction by applying a teaching-learning program using the history of science and the traditional instruction. Since this program using the history of science is effective for the attitude improvement of elementary school students as well as academic achievement, it is highly likely to be used as the science education material for students with the low affective area.

To identify interest of primary school children and find the correlations between their interest and school achievement and emotion. Cluster-sampled 410 primary school children in Seoul were interviewed by the standardized questionnaire and data were analyzed statistically by computer system. 1) High SES has positive influence on school achievement. 2) children in higher SES tend to like more in-door-play or instrumental play. 30 More spending their times with in-door-play or instrumental play, children make better school achievement. 4) There is no significant relationships between the TV watching time and emotional stability. 5) More interest I social, natural science and arithmetic, children make higher achievement in all subjects above average. 6) Children's emotion has no association with school achievement, playing types and TV watching time but has positive association with SES.

The purpose of this study is to check the educational influence and accountability of school library and to derive implications for the improvement of public education, using raw data of OECD PISA 2009. To do this, the reading achievement as well as questionnaire of 4,989 Korean students' data in OECD PISA 2009 were used. It analyzed how the visit of library can affect reading achievement, reading attitude and behavioral through structural equation modeling method. The results were as follows. The library use factor is a cause-effect relationship among reading achievement, reading attitude and behavioral factors. In addition, the reading attitude is a cause-effect relationship between reading behavior factor and reading achievement. In the part of reading behavior is a cause-effect relationship reading achievement. In the results of applying this causal relationship of whole population, in some individual cases, they are activated as moderating variable.
