This study was analyzing what studying factors are affecting on the development of science process skills of the 5th graders in the elementary school. For this research, 2 hundreds of elementary students were chosen and questioned on 3 factors like teacher, school environment, and learning strategy which are supposed to affect the development of science process skills. According to the result, there were differences in the categories according to the region. Especially, science process skills were significantly different in level of school category(p<.05)). Science process skills were significantly correlated with teachers and school category, and learning environment in 5th grade. Based on these results, it is expected to perform analysis about the influences that studying variables have on science achievement and attitude as well as scientific reasoning ability. Also, further study is needed about the influence that these small difference have on middle and high school students, though studying variables are not statistically significant on this research.

The purpose of this study was to examine the effects of emotion, home environment, school environment on self-regulated learning, focusing on motivational and behavioral regulation. Participants are 2070 students from 95 middle schools of Korean Children and Youth Panel Study(KCYPS). The variables of emotions, home environment, school environment and motivational regulation, behavioral regulation were analyzed using correlation analysis and multiple regression. The results were as follows. First, emotion, home environment, school environment were correlated with on motivational and behavioral regulation. Second, emotion explained motivational regulation and behavioral regulation of self-regulated learning as well as home envionment and school environment. All subvariables of emotion were significantly related to behavior control. Third, among subvariables of home environment, parents education and occupations, and annual household income were not significantly related to motivational regulation and behavioral regulation. However, home economic level perceived by students and parents' interest and abuse on students had great effects. Forth, school environment has a greater explanatory effect on motivational regulation and behavioral regulation. Particularly, friendships and relationships with teachers during learning activities had a significant effect. These results showed that emotion and psychological environment of learning environment are important variables affecting on self-regulated learning and suggests the need for researches on these variables.

The purpose of this study is to verify analysis of self-efficacy and self-confidence of the athletes. The subjects of this study were selected 200 athletes who have a highschool athletes in Seoul. The data-collecting method use of self-confidence by Kim(1999) and self-efficacy by Kim(2002) & Lee(2003). The Descriptive Statistical Analysis Correlation Analysis and Regression Analysis As a result, Frist, family interest, motivation, mentor & hobby which is sport-state/trait affected confidence. Second, family interest, motivation, mentor & hobby which is affected self-efficacy. Third, sport-trait confidence which is affected self-efficacy.

The purpose of this study is to suggest the basic data for lowering cyber university students' dropout rate and fostering continuous learning environment through understanding that cyber university student's private variance, an education institute variance and social variance have the impact on a student's determining dropout. For this, we selected students in A cyber university and carried out surveys for 500 students from April first to May 31st, 2009 using convenience sampling. We excluded answers whose results are considered to be insufficient or overlapped among answers of 336 students and used 304 answers in this study. We carried out logistics regression analysis using SPSS for Winow 15.0 for data analysis. First, it proved that individual interest variance affects the dropout. Second, it turned out that educational institute's environment variance has impact on the dropout. Third, it proved that social environment factor affects the dropout. Fourth, only individual variance among individual, an educational institute and social variance has meaningful impact on the dropout in terms of statistics.

The purpose of this study is to examine the variables related to the students' e-learning participation that have an effect on learning achievement in e-learning environment of cyber universities. Based on the related research, the followings are derive. First, students' attendance and participation in discussion showed higher correlation with the learning achievement than other participation variables. However, the total studying time in online classes showed lower correlation with the learning achievement. Second, the variables that have an effect on the learning achievement were in the order of students' attendance, participation in discussion, access frequency to online classes, learning progress and number of data uploads. Third, by the learners' background, the difference among the variables that have an effect on learning achievement were found. Based on the results above, this study suggests considerations about participation variables to enhance the learning achievement in cyber universities.

The purpose of this study was to investigate language receptive characteristics of children with multicultural families in according to living areas. The subjects were 132 mother with children for living multicultural families 3 to 6 years old. The results were as follows. First, the differences of home environment on nationality, all variables were significant differences on emotional atmosphere, experience's variety, and play data in statistically. Second, the differences of home environment on age all variables were significant differences on permission, independent's upbringing emotional atmosphere, experience's variety and physical environment in statistically. Third, the differences of home environment on educational background, all variables were significant differences on predictable environments, developmental stimulation, quality of language environments, permission, independent's upbringing emotional atmosphere, experience's variety, physical environment and play data in statistically. Fourth, the differences of home environment on communication method in home, all variables were significant differences in statistically as communication(general korean) they use in home. Fifth, the differences of home environment on occupation existence, all variables were not significant differences in statistically.
