In this thesis, we suggested an e-learning model, which is named 'goal driven personalized e-learning system' to improve educational effects, and implemented it. The system makes the learner choose the learning goal which could be a motivational power for learning, so it enabled self-directed learning. In order to implement the system, we proposed new standards related to personalization by modifying SCORM 2004 standard. New standards stand for the statistics on learning objects usage, a goal for driving learning. and information of the contents model and the sequencing information model, which are parts of the system previously suggested. We implemented the system, and then proved that personalize e-learning is possible by showing that the system could offer a learning path individually to learners who have different characteristics.

This study aims to identify the structural relationship between mastery-approach goal orientation, instructor support, problem solving, collaborative skills, and course satisfaction among students who participated in project-based learning. To achieve the purpose of this research, researchers have conducted surveys between June and December in 2019. A total of 283 cases were selected for analysis. According to the study, mastery-approach goal orientation and instructor support have positive effects on problem solving and course satisfaction. Instructor support has positive effects on collaboration skills, and problem solving has positive effects on collaboration skills and course satisfaction. Also, the mediating effect of problem solving in the relationship among mastery-approach goal orientation, instructor support, collaboration skills, and course satisfaction was found to be statistically significant. However, the path between mastery-approach goal orientation and collaboration skills was not statistically significant. Based on these findings, academic and practical implications were suggested.

The purpose of this study was to explore the latent profiles of social achievement goals and to investigate the differences in peer status (perceived popularity, social preference) and aggression (overt, relational, cyber) among those profile groups. Social achievement goals and cyber aggression data was acquired through self-reporting, and perceived popularity, social preference, and overt and relational aggression were assessed through peer nomination. Applying the latent profile analysis(LPA) to 1,239 elementary school students, three distinct groups of social achievement goals were identified: a development-oriented achievement goal group, an average social goal group, and a overall-high social achievement goal group. Using logistic regression analysis, the relationships between the latent group, peer status, and aggression were examined. The result indicated that the higher the social preference, the lower the probability of belonging to the 'overall-high social achievement goal group'. And the higher the cyber aggression, the lower the probability of belonging to the 'development-oriented achievement goal group'. In addition, the higher the relational aggression of the second time, the higher the probability of belonging to the 'overall-high social achievement goal group' as compared to the 'average social goal group'.

The purpose of this study is to identify the causal relationship among perceived instrumentality, mastery goal orientation, self-regulated learning and academic achievement in cyber education. 317 current students of the W cyber university participated in the study. The results of structural equation modeling analysis are as follows: First, endogenous instrumentality affects mastery goal orientation. Second, mastery goal orientation affects self-regulated learning. Third, while exogenous instrumentality had negative effect on academic achievement, self-regulated learning was the only variable that had positive effect on academic achievement. In addition, the result indicated that endogenous instrumentality had indirect effect on academic achievement and self-regulated learning mediated between mastery goal orientation and academic achievement.

The purpose of this study is to investigate science teachers' orientation toward scientific inquiry-based teaching. In this study, five middle school science teachers formed and participated in a teacher learning community for scientific inquiry-based instruction during one year. Data collection consisted of pre and post questionnaire and interviews, audio-recordings of teachers' collaborative lesson planning and reflection on teaching practice, and field notes of participant teachers' teaching practice and follow-up interviews. Data analysis indicated that there were four orientations toward scientific inquiry-based teaching. They were knowledge and beliefs about 'goals of scientific inquiry-based teaching', 'scientific inquiry-based teaching and learning', 'argumentation-based teaching and learning', and 'nature of science and science inquiry'. Teachers' collaboration in a teacher learning community would be effective in facilitating teachers' orientation to scientific inquiry-based teaching.

Outdoor education emphasizes diverse experiences from the internal growth which is expected from the learners, to the ecological and environmental experiences. It is also the needs of this time and reflected in the education system of Korea. However the goal of outdoor education is not well defined and philosophical efforts to clarify it is also not enough. In this respect, we tried to define the goal and investigated professionalism of outdoor education. Specifically, we investigated the professionalism of teachers and instructors of physical education. The goal was investigated in two areas 1) holistic experience and problem solving skill and 2) aiming self-reflective practitioner. The idea was that educators must not aim simple educational efficiencies but have to become self-reflective practitioners through everyday life. The conclusions of this study are firstly, a safety manual is required to avoid possible injuries and to give first aid in an unfortunate occasion, secondly, an education program is required to train outdoor professionals and lastly, outdoor education should not remain in the boundary of formal education but should be included in non-formal education.

Purpose: This study was performed to offer some more effective marketing strategies for optical shops on a basis of analyses of what lifestyles influence most on 'store selection' and 'recommendation intention' and of what properties of 'store selection' influence most on 'recommendation intention'. Methods: Questionnaire surveys were conducted from the customers who visited the optical shops in Seoul and northern Gyeonggi-do region from January 1 to June 30, 2014. It was analyzed via utilizing SPSS v.20.0 statistical package program. Results: The results in lifestyle-factors which influence on store selection were arranged in order as follows: 'stability oriented', 'goal oriented', 'cultural activity oriented'. And the results in value-factors which influence on 'recommendation intention' were arranged in order as follows: 'stability oriented', 'health oriented'. The most positive factor for 'recommendation intention' was revealed as 'dealing with customers' among several factors of 'store selection'. Conclusions: Today's marketing activities for customers should be suited for different lifestyles of customers. Customers who have 'stability oriented', 'goal oriented', and 'cultural activity oriented' lifestyles tend to select optical shops in consideration of 21 items when selecting an optical shop. Customers who have 'stability oriented', and 'health oriented' lifestyles have positive influences related to 'recommendation intention'. Also, it is likely for customers to recommend optical shops to others when the factor 'dealing with customers' meets their expectations.

This paper presents a goal-oriented test data generation technique that specializes concolic testing. The proposed technique, referred to as GCT (Goal-oriented Concolic Testing) produces test inputs which execute a specific target. Concolic testing can be seen as the brute force approach to search the space of all possible paths until a required test input is found. In contrast, GCT restricts the number of program paths that are explored by using data flow information to identify statements that should be executed beforehand in order for the target to be executed. We conducted experiments to evaluate the performance of GCT with programs with flag variables to show its effectiveness.
