The purpose of this study is to explore the effects of the contextual variables on mathematics achievement based on TIMSS(the Trends in International Mathematics and Science Study) 2007 using Path Analysis with SEM(a Structural Equation Model). The books in the home, the highest level of education of mother, the highest level of education of father, the ambitions of education, the towards mathematics, the frequence of self study, and the times of homeworks are used as independent variables. The Mathematics achievement is dependent variable. The results of this analysis are as follows. First, parents' the highest level of education, the books holdings at home, and the towards effect the ambitions of education. The Mathematics achievement is indirectly being affected by them. Second, The Mathematics achievement is indirectly being affected by the ambitions of education, the towards mathematics, and the times of homeworks.

This study analyzed whether the suitability of strategy is playing a regulative role between IT characteristics & user characteristics and non-financial performance empirically. To this end, this study set up IT characteristics and user characteristics as independent variables, and set up non-financial performance as the performance variable of KMS, and also set up the suitability of the management strategy & informatization strategy of a business as moderating variables. This study defined the detailed factors in IT characteristics as IT maturity and IT/IS infrastructure while defining the detailed factors in user characteristics as perceived profit, organizing of learning, and user professionalism. In addition, this study defined non-financial performance as an organization member satisfaction, and KMS availability. As a result of the analysis, IT maturity & IT/IS infrastructure, which are defined as IT characteristics, and perceived profit, organizing of learning and user professionalism, etc., which were defined as user characteristics, were found to be variables playing a regulative role in non-financial performance.

Recently, with the attention of future vehicle technology, automobiles that are influenced by user experience(UX) are regarded as living space. However, the concept of term, definition, and constituent factors of driving experience have not been established so far. The purposes of this study are to define driving experience in terms of UX and to extract experience factors. We conducted the 18 drivers interviews and studied literature reviews. The collected interview data was analyzed by bottom-up method based on the grounded theory. And we reconstructed it through the top-down approach, based on the results of the literature review. As the result, the 'driving experience' is a concept that means all the emotions, perceptions, and cognitive outcomes on the basis of personal characteristics that drivers have in anticipation of the driving situation from the start to the destination Respectively. Nine factors that constitute driving experience were extracted by 'internal UI factors', 'environmental factors' and 'user related factors'.

In physics education, the research on students' conceptions has developed in the discussion on the nature and the difficulty of conceptual change. Recently, mental models have been a theoretical background in concrete arguments on "how students' conceptions are constructed or created." Mental models that integrate information in the presented problem and individual knowledge in their long-term memory have important information about not only expressed ideas but also in the thinking process behind the expressed ideas. The purpose of this study is to investigate the forming process and the characteristics of high school student's mental models about circular motion, and how they were changed by instruction. We used the think-aloud method based on the instrument for identifying student's mental models about circular motion, pretest of physics concept, mind map and interview for investigating student's characteristics. The results of the study showed that instructions based on the mental model theory facilitated scientific expressed model, but several factors that affected forming mental models like epistemological belief didn't change scientifically after 3 lessons.

TIMSS-R 등 국제적 검사 결과로부터 알 수 있듯이 우리 학생들의 수학교과에 대한 정의적 영역의 성취도는 매우 낮은 실정이다. 진정한 의미의 수학적 힘은 인지적 영역과 함께 정의적 영역에 대한 의미 있는 학습을 통해서 길러진다는 사실을 생각할 때, 이는 우리 수학교육이 당면하고 있는 심각한 문제점이 아닐 수 없다. 본 논문에서는 이미 밝혀진 수학 기피요인들을 이용하여 학년이 올라감에 따라서 우리 학생들의 수학적 성향이 어떻게 변화하는지를 살펴보고 수학적 성향의 교육과 관련하여 몇 가지 제안을 하였다.

The purpose of the research is to categorize math learners into pattern through those tools that distinguish math learning style for middle school students. On the ground of survey for 976 middle school students, the fact that there are 16 different math learning style at the result of cluster analysis is confirmed and the results are compared and analyzed previous research. Also according to the each constituent of math learning style, dissimilarity of distribution about learner of different sexes and grades are analyzed. It's helpful to understanding the whole characteristics of learners regarding math learning to figure out their cognitive and affective learning styles through the tools to distinguish their math learning styles.

To obtain a fruitful outcome in intellectual property (IP) education in colleges, it is essential to identify the affecting factors. The relationships between the factors were to be analyzed as a structural equation model. The IP education achievement was measured by the IP total score. The students' characteristics (input factor) were measured by defining the characteristics, parents' expectations, and IP interest. The characteristics after highschool (process factor) were observed as college satisfaction and learning attitude. Students with excellent defining characteristics have not only high college satisfaction but also an excellent learning attitude, so they have a high IP total score. Using indirect effects analysis, the path through which the defining characteristics indirectly affects the IP total score through college satisfaction and learning attitude was identified. This is consistent with the prediction that self-directed students will have high participation in IP classes and achieve excellent results. The IP interest was found to have no significant effect on the IP total score. This contradicts the belief that students with high IP interest will actively participate in IP classes and earn high scores, which is because it overlooks the possibility that participation in IP activities in high school is semi-forced.

This study proposed the concept model of ICT-based Creative Talented Persons as the type of persons that gifted education in the ICT area should cultivate for the 21st century. The model of ICT-based Creative Talented Persons is made of three dimensions by 3 core competencies, 9 traits, and 27 characteristics. The field experts, that is, teachers on elementary and secondary school levels evaluate the validity of the model. Teachers expressed positive opinions about the validity of the multi-dimension model of ICT-based Creative Talented Persons. We expect that this model can provide a useful guide to designing and operating ICT education and ICT gifted education for cultivating talented persons to contribute for the future society.

소프트웨어 개발 프로젝트의 15%는 시작하기도 전에 종결되며, 66%의 프로젝트는 실패로 간주되고 있다. 또한 평균적으로, 완료된 프로젝트의 43%가 비용을 초과하는 것으로 나타났다. 실제로 2002년도 미국에서 소프트웨어 프로젝트의 투자 실패로 인한 손실은 비용의 초과로 생긴 170억 달러를 포함해 총 손실 금액이 380억 달러인 것으로 추정하고 있다. 이러한 문제점을 해결하고자 하는 여러 시도 중에 하나가 ISBSG(International Software Benchmarking Standard Group, 2004)으로, 소프트웨어 프로젝트 관련 데이터를 국제적으로 수집하여 위와 같은 문제의 원인을 밝히고자 노력하고 있다. 본 연구는 ISBSG에서 수집한 데이터를 이용해 소프트웨어 시스템과 관련된 요인 중에서 기능성 품질, 문서화품질, 훈련정도, 소프트웨어크기, 전체결함수, 사업요구사항충족, 사용편리성, 목표달성이라는 6개 변수 간의 연관성을 분석하였다. 분석대상 프로젝트는 49개이고, 분석 방법으로는 SURE(Seemingly Unrelated REgression)를 사용하였다. 분석 결과 소프트웨어 기능성품질은 사업요구사항충족, 사용편리성과 정의 관계를 가지며, 사용편리성은 사업요구사항충족과 정의 관계를 가지는 것으로 밝혀졌다. 또한 사업요구사항충족은 목표달성과 정의 관계를 가지고 있다.
