In this paper, the researchers investigated the influence of graphing calculator in learning the concept of linear function for the gifted students. Elementary students who were taking a course in enrichment mathematics at Science Education Institute for the Gifted in Mokpo National University were selected for this study. The researchers analyzed students' processes of mathematical inference and conjecture, and students' algebraic description. We found the facts that the visualization using a graphing calculator and CBL is helpful to the gifted students in understanding concepts of liner function, finding the relationship between variables, analyzing and presupposing of graph. But, using graphing calculator can be a factor that disturbs learning of students who have too much of curiosity on graphing calculator.

How to enhance the ability of underachieve students are unsolved problems for mathematics teachers despite of their best efforts to teach them. The purpose of this study is to explore the effectiveness of mathematical journal writing as a method of improving the mathematical attitudes and achievements for underachieve students. Seven students whose performances were below 40% on the final exam in the 1st semester were recruited in order to gather empirical data. Before journal writing procedures, the subjects' characteristics, learning styles and mathematical attitudes were investigated through personal interview and mathematical attitude test. After six-week journal writing, follow-up survey and mathematical attitude test were conducted. The results of this research are as follows: Mathematical journal writing had a positive effect to underachieve students on improving confidence in mathematics and a positive influence on active and effective learning attitude. And mathematical journal writing had an effect on improvement in their mathematics achievement comparing first semester's final exam with second semester's mid-term exam. Finally mathematical journal writing contributes positively to the relationship between students and their teacher.

The main goal of this paper is to examine the current English education practices in Korea in the broad context of research and academia. Furthermore, it attempts to uncover why English education has not been well established as a field of science in English-related departments and consequently what has been neglected and what issues should be dealt with to increase understanding and to create a more interactive relationship between the university and society. First, the author deals with the influence of ‘folk science’ views in the field of English education by touching on some widely held perceptions and issues. Second, by dealing with the alienation of English education and examining the phenomenon of seeing English education as a secondary field of science in English related departments, an attempt was made to reveal underlying epistemological dualism rooted in Asian cultures. Third, the paper deals with a critical issue related to English education: Exposure and Time. By reviewing and reinterpreting some of basic and fundamental literature with respect to language learning, exposure, and time, the author raises a new issue in English education and proposes new interpretation and an alternative more relativistic viewpoint; he also investigates what should be done to improve English education on the basis of research and science in order to deal with the needs and problems of society.

Today, it is not difficult to use information technology (IT), especially, Internet based ones. Many people can not only access IT without learning how to use it but also find and develop new techniques and usages which couldn't be expected by system engineers or designers. This is owing to social interactions among users as well as advancement of IT. Theoretically, such social interactions in using IT can be well explained by adaptive structuration theory (AST) which has been considered as one of trying to capture the change of using IT due to social interactions between users and system. This study is to analyze the relationship between social interactions and motivation in using IT which can determine attitude and intention of using IT. For this purpose we provide a research model, in which two AST related variables, faithfulness of appropriation and consensus on appropriation, are independent variables and three beliefs for using IT, usefulness, ease of use and playfulness, are dependent ones. Additionally, for reflection of changing uses, usefulness is formed as second order factor by two first order factors-usefulness of self-expression and communication. An empirical test of our model for blog users which is analyzed by Partial Least Square method shows supporting most of hypotheses except one, consensus-ease of use.

Our natural desire to exuviate old theory and search for new ideas means conversion and reformation. Howev-er, the new idea of the present moment will soon become an ancient history when the next generation emerges with more advanced ideas. Naturally, we have learned to accept the past history and utilized it as a the foundation for the future. Through the repeated process of the learning method, the popula-tion cultivate themselves with proper understanding and appropriate attitude toward design. By analyzing social behaviors of the past and living conditions, we can ex-pand our imaginations beyond limits. Each society and its local condition have tremendous effects on the develop-ment and progress of artistic theories, techniques and craftsmanship, and potential design of every day use products. Today, interior design can not afford to ignore the or-ganic relationship of life style and space. Thus, the plan-ning of space means the planning of life style. Life style, as it is, has a vast definition and changes with time. That is why spaces, which consider the life style and its environment when designed, show different aspects ac-cording to its corresponding time. Interior design, in particular, differs by time and re-gion to create its unique style. The change in space is the natural result of the change in life style which again is sensitive to the change in cultural and environmental elements. Design is no longer designing of mere physical elements and environment. Design should be taken as the equivalent of creating spiritual culture.

Problem-solving ability is one of the most important learning outcomes for students to compete and accomplish in a knowledge-based society. It has been empirically proven that visualization plays a central role in problem-solving. The best performing problem-solver might have a strong visualization tendency. However, there is little research as to what factors of visualization tendency primarily related to problem-solving ability according to phases of problem-solving. The purpose of this study is to identify the relationship between visualization tendency and problem-solving ability, to determine which factors of visualization tendency influence problem-solving ability in each phase of problem-solving, and to examine different problem-solving ability from the perspective of the levels of visualization tendency. This study has found out that visualization tendency has a significant correlation with problem-solving ability. Especially, Generative Visualization and Spatial-Motor Visualization as sub-visualization tendency were more strongly related to each phase of problem-solving. It indicates that visualization tendency to generate and operate mental processing can be considered a major cognitive skill to improve problem-solving ability. Furthermore, students who have high visualization tendency also have significantly higher problem-solving ability than students with low visualization tendency. It shows that the levels of visualization tendency can predict variables related to students' problem-solving ability.

The purpose of this study was to examine the influence of teacher efficacy and stress coping strategies on job satisfaction of teachers in early childhood education and care. 189 teachers were recruited from 8 day care centers and 10 kindergartens in Seoul, Kyunggi, Kyungbuk, and Chonbuk provinces in Korea. Data were analyzed through frequencies, Pearson's correlations, and the stepwise regression analyses using PASW 18.0. The findings are as follows. First, the result showed that teachers in ECEC were most likely to be satisfied with their job characteristics most among the 4 subcategories in job satisfaction. They also perceived their the ability of discipline high for teacher efficacy, and used the direct coping strategy most as a stress coping strategy. Second, the teachers' ability to create a positive learning atmosphere affected job characteristics, the ability to participate in decision-making affected the relationship with director and colleagues, working environment, welfare and salary the most. Third, the direct coping strategy had the most impacts on all subcategories of job satisfaction. The results of this study may provide basic data for finding effective way to increase job satisfaction of teachers in ECEC.

Previous researches have been conducted on the drivers of alliance performance up to date. Unlike existing literatures, we examine the influence of alliance management capability as direct drivers on venture's alliance performance. Based upon organizational capability theory, we proposed that coordination capability, relationship capability, learning capability are main components of alliance management capabilities. In addition, we proposed capability of CEO as forth alliance management capability in global ventures. Using 78 global ventures as research sample, this study shows that these four alliance capabilities have considerable influence on financial performance of ventures with global alliances.

This study is an empirical analysis on the relationship between social presence and online community users' continuance intention. Based on Bhattacherjee(2001)'s expectation-confirmation model (ECM) of IT continuance model, we test the influence of social presence on one's intention to continue using online communities. This study sampled 132 online community users. Research hypotheses are tested using the structural equation modelling(SEM) approach. The results of this study demonstrate that user satisfaction is influenced by perceived usefulness and perceived enjoyment. But, the confirmation of expectation did not affect user satisfaction. And, social presence has direct effects on perceived usefulness and perceived enjoyment. Further, social presence has a positive effect on users' continuance intention through mediating effect of perceived usefulness. This study suggests that perceived usefulness should be taken into account when carrying out the operating strategy of online communities.
