The study has compared the effects in SNS-utilized instruction that each of self centric activities and social interaction added social activities affected self initiative, attitudes and self efficacy to information technology respectively. The research methods utilized the pre experimental design as nonequivalent experimental group. The data was analyzed by paired t-test and content analysis. The results showed that the SNS class utilized self-centric activities were effective in self-initiative and attitudes toward information technology, while social interaction added social activities were effective in not only self-initiative and the attitudes of information technology but also self efficacy of information technology. And content analysis of the effects of the education showed that information sharing, instancy and accessibility were advantageous but information security and privacy issues were problematic. That is, it was confirmed that when self-centric activities and social interaction activities were practised simultaneously in SNS-utilized instruction, the self initiative which learners planed and executed by themselves, the attitudes and self efficacy of information technology which were able to enhance learning ability and to show satisfaction to individual learning were improved.

The purpose of this study was to examine the effect of teaching science ethical issues relevant to the middle school science curriculum. The experimental subjects were 132 second grade middle school students in Seoul, who were divided into two groups without any statistical differences. The results of this study indicated that teaching ethical issues in science had a positive influence on students' attitudes toward science and fostered a positive impression of science education. Also, the students showed a positive attitude in dealing with ethical problems in science and technology. Regardless, the results of this study suggest that ethical education in science classes is effective in increasing positive attitude toward science and the ability of the students in addressing and resolving ethical problems in science and technology. As such, we strongly recommend that the science curriculum for middle school students be changed to integrate ethical issues in the science class.

Recently, the development of ICT(information & communications technology) with the advent of new media paradigm shift in learning has brought a dramatic impact on the competitiveness of universities. The previous studies on the academic performance of e-learning mainly targeted on e-learning users, studying additional synchronization and system quality factors to measure academic performance. This study empirically analyzed the learning flow and academic performance considering both DeLone & McLean model system quality and synchronizing factors based on ARCS model. Relating to quality and synchronization factors, the academic performance of e-learning system was tested, and the difference between learning flow and academic performance was also analyzed based on time-series data, by the test difference(in the beginning, during, and final of the semester). The results of the study are as follows. First, the study shows that both system quality and synchronization directly affected the learning performance. Thus, when designing e-learning system, it is necessary to consider these two factors at the same time. Second, the indirectly mediating effect on the system quality and synchronization factors turned out to be significant in learning flow. Third, the result of regression analysis on the contents of utilizing dummy variable presents that the teacher's explanation has greater influence than multimedia has to the academic performance, and furthermore, the test difference showed no significance. Further research should be undertaken to consider the learner's degree of acceptance which reflects various aspects for building m-learning or u-learning.

The purpose of this study is investigate the level of awareness and interest of middle and high school students on performance evaluation book list, and regarding the correlation analysis of general satisfaction and academic achievement. For this purpose, each of the two middle schools and high schools in Seoul were selected, a total of 200 people were surveyed for each 50 students in each gender and grade. Research results, First, the analysis of gender and school level showed that there were differences in level of interest in performance evaluation books. Second, the analysis of differences in the level of interest in the list of performance evaluation books showed that students interested in the list of performance evaluation books spend more time evaluating performance. Third, the analysis of differences in level of awareness in the list of performance evaluation books showed that the relationship between knowledge acquisition and academic achievement was high depending on whether they were ware. There was also a significant relationship between selection criteria and general satisfaction.

The purpose of this study was to examine the effects of career identity on learning persistence and academic achievement, and mediating effect of utility value. To examine the effect of mediating role of utility value, we divided utility value into two types, utility value of daily matters and utility value of career. This study was conducted on 228 senior students in high school, to investigate relations among career identity, utility value, learning persistence and academic achievement in mathematics, by using the structural equation model. The results are as follows. First, career identity positively predicted learning persistence in mathematics. Second, career identity positively predicted the utility value of daily matters and career. Third, both type of utility value in mathematics positively predicted learning persistence in mathematics. Fourth, the utility value of daily matters and career, in mathematics subjects, showed differential predictability toward learning persistence and academic achievement. Both type of utility value in mathematics positively predicted learning persistence, but showed differential predictability toward learning academic achievement. Specifically, the utility value of daily matters in the near future did not predict the academic achievement, but the utility value of career in the distant future positively predicted the academic achievement. Fifth, the utility value was found to play a mediating role in the relationship between career identity and learning persistence. Based on the results of this study, implications for mathematics education were discussed.

The U.S. military has been developing support policies for the soldiers dispatched overseas and their families since WWI. It is classified by the period nowadyas as follows. Prior to the dispatch, support for money and housing issues is mainly provided. During the dispatch, the DOD level community is formed to strengthen relations between the soldiers and their families, check their children's academic achievements, etc. After returning to the military, the mental and physical health care for not only the soldiers but also their families is provided. Based on these facts, this research proposes that the ROK MND's overseas dispatch instruction upgrade to law in order to provide housing support, even if the families don't live in military houses. Simultaneously, an online community is needed to be open for sharing information between them, their children's educational achievements, etc. More importantly, the mental health care for both the sodiers and their families is provided for a certain period.

This research will target the Dental Hygienics students to identify the level and type of the $2{\times}2$ achievement target orientation, and will study how this achievement target orientation is related to the Self-Regulated Learning, as well as the effect on the each sub elements of the Self-Regulated Learning (SRL). Among the $2{\times}2$ achievement target orientation of all the female university students, the skillful approach was found to be highest. In case of the adjustment of the motivation following grade, intrinsic value of the 1st grader was higher than the intrinsic value of the 2nd and 3rd graders. As for the behavior adjustment, the 3rd grader's time and studying adjustment were found to be higher. Mean while, pursuit of the cooperation was found to be high compared to the time and studying adjustment of the1st and 2nd graders. Second, intrinsic value, overt goal orientation, and studying environment adjustment among the SRL's subelements, manifested significant correlation with all the sub elements of the $2{\times}2$ achievement target orientation. As for the elements that affected cognition adjustment, grade and skillful approach were found to exert significant effect on the performance adjustment. As for the element that affects behavior adjustment, grade and skillful approach exerted significant effect on the sub elements of the behavior adjustment. Analysis on the effect of the achievement target orientation and SRL implies that the direction of the students' learning goal can be modified and that they can learn effectively by using the SRL appropriately. When the two elements are factored in carefully, the key findings could serve as a base data that can motivate the students, inducing effective learning process.
