The elementary school English Education Course consists of four integrated aspects of language (Listen, Speak, Read, Write) used to develop skills for daily communication in English. yet the 6th Grade English Education Curriculum focuses almost exclusively on sentence completion through copying and "fill-in-the-blank" exercises. Further, these activities are insufficient time to develop literacy skills. Additionally, the curriculum's emphasis on memorization within the written component is very time consuming for students, leading many to develop negative opinions of the written aspect of a comprehensive understanding of English. This thesis attempts to address each these problems through development of a web-based Learning Model for Cooperative Writing in English. The study resulted in three observations. First, this model overcame limitations of the current teaching model in schools. Second, students expressed more interest in the experimental model than in the current curriculum and standard pedagogical methods. Finally, the study demonstrated that improvement of English literacy is indeed possible using the model presented here.

Facial expressions decide an image for the individual, and the ability to interpret emotion from facial expressions is the core of human relations, hence recognizing emotion through facial expression is important enough to change attitude and decisions between individuals within social relations. Children with unstable attachment development, seniors, autistic group, ADHD children and depression group showed low performance results in facial expression recognizing ability tasks, and active interventions with such groups anticipates possibilities of prevention and therapeutic effects for psychological disabilities. The quantified figures that show detailed change in position of lips, eyes and cheeks anticipates for possible applications in diverse fields such as human sensibility ergonomics, korean culture and art contents, therapeutical and educational applications to overcome psychological disabilities and as methods of non-verbal communication in the globalizing multicultural society to overcome cultural differences.

The purpose of this study is to develop value instruction program which can deal with geographic value problem(GVP) in geographic education. This program is organized into seven stages: identification of GVP(reading of content of GVP, and categorization and description of action which involved in content), analysis of GVP(comparison and analysis of GVP, and ordering of value positions), decision making, justification of decision making and actualization. The processes of decision making and their related activities are emphasized in this program. In experimental classroom, it took effects to providing subjective experiences with students, developing decision making ability, and giving responsibility of decision making. Therefore this study suggests that this program helps students to improve their social participation ability as the democratic citizenship.

유기물 나노 복합체는 고집적/저전력/플렉서블 특성을 가지는 초고효율 비휘발성 메모리 소자를 제작하는데 많은 이점을 가지고 있어, 차세대 비휘발성 메모리 소자에 사용되는 소재로 매우 각광받고 있다. 그 중, WORM 특성을 가지는 메모리 소자는 1회 쓰기 후 수많은 읽기가 가능하기 때문에, 그 효율성이 매우 뛰어나 이목을 끌고 있다. 유기물 나노 복합체 중에서, poly(3-hexylthiophene) (P3HT)는 화학적/전기적 안정성과 전하의 이동도 특성이 뛰어나기 때문에 전자 소자에 응용하려는 연구가 활발히 진행되고 있다. 본 연구에서는 $P_3HT$ 고분자를 polymethylmethacrylate(PMMA) 고분자에 분산시킴으로써, 상태를 기억하는 저장 매체로 사용하였다. 본 연구의 소자를 제작하기 위하여 약 9 : 1 비율을 가지는 PMMA 와 $P_3HT$를 용매인 클로로벤젠에 녹여 용액을 준비하였다. Indium Tin Oxide (ITO)가 코팅된 glass를 화학적 처리를 통해 청결하게 만든 후, PMMA와 $P_3HT$가 용해되어 있는 용액을 스핀 코팅 방법으로 박막을 형성하였다. PMMA 속에 $P_3HT$가 분산되어 있는 활성층 위에 상부 전극으로 Al을 열 증착 방식을 통하여 형성하였다. 제작된 WORM 특성을 갖는 유기물 나노 복합체 플렉서블 소자의 메모리 효과에 대한 분석을 위하여, -5V에서 5V까지 전압을 인가하여 전류-전압 특성을 측정하였다. 초기 낮은 전도도 (OFF 상태, 10-10A에서 10-4A)를 유지하다가, 쓰기 전압을 1회 가해준 후부터는 높은 전도도 (ON 상태, 10-5A 에서 10-2A)를 유지하는 특성을 관측하였다. 또한 WORM 특성을 갖는 메모리 소자로써의 능력을 보여주기 위하여, 1회 쓰기 전압 후 읽기 전압인 1V를 인가하여 높은 전도도 상태에 대한 상태 유지 능력을 측정하였고, 전하 수송 메커니즘을 규명하기 위하여 피팅 모델을 통해 설명하였다.

The purpose of this study was to explore and to suggest the effective teaching methods for university students to improve their speaking abilities through peer assessment-feedback and self assessment-feedback based presentation and debate class. The objects and content of the study were the students who took a class "Reading and Communication" of H university, and here examine closely the speaking activities and their effects during the integrated activities of 'reading, speaking and writing'. In speaking education peer and self assessment feedback is to form an emotional consensus among the students and encourage active participation, and enable self-discovery and communication learning to students. As a result of the study, it was found that the variety speaking practice had a very positive effect on the attitude of speaking and the psychological aspect, and it was confirmed that the evaluation and feedback activities had a meaningful learning effect on the students. Effective speech education and guidance measures should be continuously studied and developed.

The study aims the introducing the items for the assessment of mathematical thinking including mathematical reasoning, problem solving, and communication and the analyzing on the responses of the 5th grade pupils. We categorized the area of mathematical reasoning into deductive reasoning, inductive reasoning, and analogy; problem solving into external problem solving and internal one; and communication into speaking, reading, writing, and listening. And we proposed the examples of our items for each area and the 5th grade pupils' responses. When we assess on pupil's mathematical reasoning, we need to develop very appropriate items needing the very ability of each kind of mathematical reasoning. When pupils solve items requesting communication, the impact of the form of each communication seem to be smaller than that of the mathematical situation or sturucture of the item. We suggested that we need to continue the studies on mathematical assessment and on the constitution and utilization of cognitive areas, and we also need to in-service teacher education on the development of mathematical assessments, based on this study.

The purpose of this study is to research psychological and social devices to foster self-regulated learning of Korean adolescents. This study investigated metacognitive, motivational, and behavioral factors of self-regulated learning through current research. In terms of metacognitive factors, we reviewed the importance of cognitive and metacognitive learning strategies of adolescents for better self-regulated learning. Especially we gave a great emphasis on the role of comprehension monitoring metacognitive strategy for the learning to read in this review. For motivational factors, recent research of self-regulated learning has tended to focus on self-efficacy and goal orientation. The current research examining behavioral factors of self-regulated learning has tended to focus on time management and academic procrastination. Research findings in the motivational aspect suggest that we need to develop the program to improve adolescents' self-efficacy and recognize new re-conceptualization of the goal theory. Research findings in the behavioral aspect recommend practical tips and strategies to improve time management skills and to overcome academic procrastination. Finally, future directions for research are discussed.

We investigated the proper display environment for japanese electronic character reading lessons through the experiment with a projection TV and a computer. For the purpose of finding out the effect of prior learning activities at the context of authentic Japanese text orthography, which includes dual notation, words spacing, etc., we also made an experiment on comprehending the web documents which are extracted from japanese web sites. From the experimental results, we acquired a conclusion that two approaches are needed to enhance the ability of comprehending Japanese web documents which is newly added to the 7th curriculum revision. For short-term approach, we need to utilize Japanese web documents as learning materials. For long-term approach, we have to reconsider whether the orthography of the current Japanese textbooks is suitable or not.

This study is part of a larger project that investigated the patterns of children's use of educational graphic novels (EGNs), a publication format that has been popular among young readers in Korea since 2000. In-depth interviews with elementary school teachers and school librarians uncovered tension and gaps between these adult professionals and children's enjoyment of the format. Interviewees' views on EGNs ranged from limited tolerance to a potential candidate for high-interest / low-vocabulary reading. All teachers and school librarians urged for guidelines and criteria for selecting and evaluating EGNs for children.
