The purpose of this study was to verify that students' interest in team activities for problem solving, the effect of interest on it, and students' changes in perceptions and their behavioral characteristics in the process of problem solving. The study reviewed documents prepared by students, such as work sheets, descriptive questionnaires, works and their photos, student activity photos and observation journals of teachers. The results of this research are as below. First, a problem solving team activity for making a model car was considered an interesting assignment by more than 90% of male/female students. The fact that female students could be more focused on this assignment than male students was discovered. Interest in the assignment not only had an influence on the points from the start (the blueprint) to the end (model cars completed based upon the designs) of problem solving, but also provided the traction power behind the assignment. Second, the problem solving team activity allowed the students to change their existing recognition (thoughts) while positively taking a lead or indirectly utilizing various learning experiences (including experiences of failure). Third, $2^{nd}$ graders in middle school had a tendency to solve problems in dependently rather than to receive help from others when they encountered problematic situations.

The Picturesque Style of the $18{\sim}19th$ Century Romantic landscape gardening had features of both irregularity and variety. These features were applied to $19{\sim}20th$ Century urbanism, which was called 'Urban Picturesque'. Preceding research has found that pedestrians take more interest in streets modeled after 'Urban Picturesque' principles mainly focused on physical appearance. further development of this research was undertaken through an experiment focused on pedestrian activity as well as physical factors through a case study of the Duksugung-gil, Insadong-gil and Myoungdong-gil. The results of the research are as follows. Although the physical conditions of the street in Duksugung are fitted more on Urban Picturesque principles than the other two case studies, the degree of pedestrian interest was highest for the street in Insadong due to excellence both in physical appearance and the diversity of cultural activities available in it. In conclusion, it can be said that to achieve the fdl effect of a Picturesque urban scene, a diversity of place-appropriate activities related to socio-cultural programs should be combined with an excellent physical appearance.

This study analyzed the meaning and functions of '-(으)ㄹ 것 같다' and '-나 보다' among the various semantic functions depending on the situation, and discussed ways to train speculative expressions more efficiently by expanding them from traditional teaching methods through visualizations applied visual thinking at real Korean language education. The speculative representation, which is the subject of this study, represents the speaker's speculation about something or situation, with slight differences in meaning depending on the basis of the speculation and the subject of the speculation. We propose a training method that can enhance the diversification and efficiency of teaching-learning through visualization of information or knowledge, speculative representations that exhibit fine semantic differences in various situations. Utilizing visual thinking in language education can simplify and provide language information through visualization of language knowledge, and learners can be efficient at organizing and organizing language knowledge. It also has the advantage of long-term memory of language information through visualization of language knowledge. Attempts of various educational methods that can be applied at the Korean language education site can contribute to establishing a more systematic and efficient education method, which is meaningful in that the visual thinking proposed in this study can give interest and efficiency to international students.

The purpose of this study was to design the new teaching strategy based on the particulate model facilitating the reflective thinking (RE-PM) in the learning of the particulate nature of matter, and to investigate the effect of the new teaching strategy in compare with the traditional teaching strategy (TS-PM) after treating with new teaching strategy on preliminary teachers of elementary school. The problems of traditional teaching strategy are as follows: 1) Most of students didn't think the particulate model connected with practical material. 2) Most of students have a tendency of the rote memory on learning of the traditional particulate model. 3) The ratio of changing the view of continuous matter into the view of particulate nature of matter was very low, after learning the particulate model using of the traditional teaching strategy. The new teaching strategy facilitating the reflective thinking was more effective on the understanding of particulate nature of matter and the driving of motivation than the traditional teaching strategy in the learning of the particulate nature of matter.

Many students feel the word problems are very difficult. This study analyzes the linguistic and cognitive factors that affect word problem solving so that we help students bring through the difficulty. There are a text base, a situation model, and a real world in the linguistic aspects. Students have a difficulty at the transition from text base to situation model(equation), and make lots of errors at the situation model. In the cognitive aspects, I investigated problem solving schemes, strategies, and complexity level. Students are likely to choose strategy by the contents which teacher instructed, but not by low complexity level, and mix up the amount of sugar and sugar water, and concentration. We can recognize how complex the types of word problems are to solve, which strategies students choose largely, and what errors that students make in the problem solving are.

A recommender system is a personalized decision support tool to suggest suitable products in proper manners for the benefits of both suppliers and consumers, with the assumption of full understating of consumers' needs and preferences. However, a substantial number of studies have focused on making recommender systems more accurate and efficient. Whereas, there have been a few studies on consumers' needs and preferences under their own contexts to accept recommender systems. To this end, this study attempted to find out the impact of personal sentiments and contexts on the willingness to accept music recommender systems based on the simplified "Technology Acceptance Model" and some verified variables from the precedent studies. For the study, we conducted an empirical study using surveys and High-Order Structural Equation Model (SEM). The outcomes of the research was affirmative to the research hypothesis that the personal sentiments and contexts positively affect the acceptance of the music recommender systems.

In this study, achievement emotions were compared between the gifted and regular students. The significant differences for each group were shown in all eight elements respectively in lesson situation, learning situation and test situation. Among various achievement emotions, it was also found that the gifted students showed higher level of positive achiecement emotions. Furthermore, positive achievement emotions can have positive effects in increasing the achievement level in science subject. On the other hand, the negative achievement emotions were higher for ordinary students that could have negative effets. The influential factors were recognizing the values of Science, Science experiments, positive evaluation experiences, aggressive learning attitudes, interests and knowledge, positive self-perceptions, career relationships, and teachers' recognitions. These factors influenced in imcreasing students' positive achievement emotions and decreasing negative achievement emotions. By conducting in-depth advanced conversations with students based on the above results could increase students' interest and positive achievement emotions.

There have been raised the question that students have been of no interst in mathematcs and incompetent for solving real world problem because students have been recognized mathematcs as abstract knowldege. We research whether students' modeles developed in modeling activity can mediate between concrete and abstract. The analysis of our case study revealed that students' modeles aren't decontextualized abstraction but is located in situated abstraction that is a network connecting between concrete and abstract. Thus, these modeles are a tool mediating between concrete and abstract. Also, students' modeling activities can provide students with the opportunity of being competent for solving real world problem.

The four-dimensional cycle simulator, which can recognize whether the road is ascent or descent, its gradient, and status of its surface on Virtual Reality, is introduced in this paper. On the base of these recognitions, various virtual motion path situations are displayed on LCD monitor attached ahead. These various situations may support not only the sense of realty but also an interest in a game in opposition to previous exercise cycles that might be monotonous. In this paper both analysis and estimation of basic bodily abilities for the four-dimensional cycling are addressed.

정보화된 미래사회를 준비하기 위하여, 우리나라에서는 실과의 한 영역과 학교재량시간을 통하여 컴퓨터 교육을 하고 있다. 그러나 실과 교육과정은 지나치게 기능 위주의 내용으로 되어있고, 학교 재량시간을 이용한 컴퓨터 교육에서는 타자연습이나 컴퓨터 활용교육만을 강조하고 있다. 이러한 교육은 컴퓨터와 친숙해지는 데는 도움을 줄 수 있지만, 고차원적인 사고력을 지닌 학생을 교육하는 데는 도움이 되지 못한다. 특별히 컴퓨터의 무한한 사용 가능성을 이용하여 창의적 문제 해결력을 기르는 교육은 매우 필요하다 하겠다. 이러한 문제를 해결하기 위하여 문제 해결 능력 교육, 즉 문제 상황이 주어지고 이것을 해결하는 프로그래밍 교육이 매우 유용하나, 지금까지의 프로그래밍 교육은 지나치게 언어 기술교육에 초점을 두고, 단순 반복과 암기, 아동의 발달단계를 고려하지 않음으로 인해 오히려 창의성을 해치고 학습의 흥미도를 저하시켜왔다. 이에 본 연구에서는 학생들 수준에 맞춰 구체적인 결과물이 보이고, 쉽고 흥미롭게 학습할 수 있는 프로그래밍 교육과정을 개발하기 위해 'LED 소자를 이용한 프로그래밍 교육 방안'을 설계하였다. 본 연구를 통하여서 초등학교 학생들이 쉽고 재미있게 프로그래밍에 접근하고, 고차원적인 문제 해결력을 기르는 컴퓨터 교육과정의 한 모델을 제시하였다.
