The purpose of this study was to design the coaching strategies for the problem based learning and examine 'the problem situation' to analyze the process of learning as it applies to the students' perception on problem based learning. The steps of this model were as follows: 1) presentation of the problem situation 2) confrontation of the problem 3) know/ need to know 4) definition of the problem statement 5) collection and sharing of information 6)generation of possible solutions 7) assessment of the best fit of solutions 8) presentation of the solution. Problem-based learning steps and coaching strategies were designed and implemented to 2nd grade high school students for the environment teaching unit. The results demonstrated that group discussion in the know/need to know step was most helpful for students to review what they know and generate solutions. At first students tend to state problems widely but through repeated group discussions they gradually clarified the problems. In the students' personal reflection notes and perception questionnaire of problem-based learning, many students especially showed difficulties in defining the problem statement. In contrast they participated actively in the learning process and express their opinions enthusiastically. Therefore, this study suggests that developing problem situation based on real context is of great importance for implementing a problem based teaming model continuously.

품사 태깅은 형태소 분석 이후 발생한 모호성을 제거하는 것으로, 통계적 방법과 규칙에 기 반한 방법이 널리 사용되고 있다. 하지만, 이들 방법론에는 각기 한계점을 지니고 있다. 통계적인 방법인 은닉 마코프 모델(Hidden Markov Model)은 유연성(flexibility)을 지니지만, 교착어(agglutinative language)인 한국어에 있어서 제한된 윈도우로 인하여, 중의성 해결의 실마리가 되는 어휘나 품사별 제대로 참조하지 못하는 경우가 있다. 반면, 규칙에 기반한 방법은 차체가 품사에 영향을 받으므로 인하여, 새로운 태그집합(tagset)이나 언어에 대하여 유연성이나 정확성을 제공해 주지 못한다. 이러한 각기 서로 다른 방법론의 한계를 극복하기 위하여, 본 논문에서는 통계와 규칙을 통합한 한국어 태깅 모델을 제안한다. 즉 통계적 학습을 통한 통계 모델이후에 2차적으로 규칙을 자동학습 하게 하여, 통계모델이 다루지 못하는 범위의 규칙을 생성하게 된다. 이처럼 2단계의 통계와 규칙의 자동 학습단계를 거치게 됨으로써, 두개 모델의 단점을 보강한 높은 정확도를 가지는 한국어 태거를 개발할 수 있게 하였다.

오늘날 웹은 급속도로 확산되어 교육에 있어서 필수적인 존재로 강력한 힘을 발휘하게 되었다. 사이버 교육 환경의 시대를 맞이하여 웹을 이용한 학습 활동의 비중은 점점 더 증가되었지만 대다수의 웹기반 교수 (Web-based Instruction : WBI)학습 사이트들이 비장애인 중심의 사용자 인터페이스로 설계됨에 따라 청각 장애인을 학습 공간에서 격리 시키고 학습 능력을 저하시키는 이중 장애를 발생시키고 있다. 따라서 본 논문에서는 최근 청각 장애인의 교육방법으로 대두되고 있는 이중언어-이중문화 접근법 (Bilingual Method : 2Bi 이론)을 활용하여 청각 장애인의 WBI 학습 능력을 신장시킬 수 있는 사용자 인터페이스를 설계하였다. 본 사용자 인터페이스의 특징은 다음과 같다. 첫째, 청각 장애인의 웹접근성을 고려한 인터페이스를 설계하여 청각 장애 학습자가 보다 쉽게 학습 공간에 접근하게 하였다. 둘째, 청각 장애인의 장애 정도 및 학습 성취 정도에 따라 3단계 사용자 인터페이스를 제공하여 수준별 학습이 가능하다. 셋째, 순차적 반복 학습이 가능하여 청각 장애인의 학습 능력뿐 아니라 의사소통 기능 향상에도 긍정적인 영향을 제공한다.

Recently substantial learning model is strongly demanded through which ICT could be effectively used at PBL, teaching and learning method, based on constructivism putting an emphasis on learner centered education. This thesis is designed to introduce the way to make the most of ICT when teachers try to make teaching plan applying PBL to science class. PBL courseware is designed to make teacher and student use by applying traditional science class model to the model for problem solving of PBL. analysing class according to the degree of connecting ICT with contents of learning. This paper suggests 8 stages of PBL package development and 5 stages of teaching pattern to grasp whole procedure.

세계는 이미 '정보화 시대'라는 거대한 물결에 휩쓸려 가고 있다. 그 속에 정보화 기술의 혜택을 가장 많이 받아야 함에도 불구하고 소외되고 있는 계층이 있다. 바로 몸이 불편한 장애우가 바로 그들이다. 이들이야말로 다양한 정보화 매체를 활용함으로써 더 큰 효과를 기대할 수 있으므로 본 연구에서는 이 중 마우스 사용이 가능한 정신지체아들을 위한 단계별 문자교육 시스템을 설계하였다. 이와 같이 주의 집중력이 현저히 떨어지고 학습의 효과가 단기간에 나타나지 않는 정신지체아들에게 지속적이고 단계적인 시스템을 제공함으로써 정보화 사회에 적응력을 높이고 컴퓨터 조작 기능과 문자 해득력을 향상시키는 방안을 모색하고자 한다.

The purpose of this study was to develop learning materials for the remedial curriculum, part of the 7th sequential differentiated math curricula, in an effort to fix the academic deficiencies of underachieving students, provide motivation to them and enhance their self-directed learning capabilities. The subjects in this study were the students in their second year of C middle school, who were in want of remedial education. After their mid-term and finals grades in the first semester of 2003 were analyzed to measure their academic deficiencies, remedial learning materials about math 8-A stage were developed, by modifying the textbook and existing materials, in consideration of 7-A stage. After they were utilized in remedial class, frequency analysis was conducted to find out what the students thought of the developed learning materials, and diagnosis evaluation was implemented to find out how many students passed the test, improve the materials, and suggest in which way their achievement could get better.

This study was conducted for the purpose of developing a design thinking-based capstone design instructional model for pre-service teachers. Through the analysis of literature related to learner-centered instruction, design thinking and capstone design instructional design principles and instructional models for pre-service teacher education were discovered, and core elements were derived. Based on the core elements derived through literature analysis, the capstone design instructional design model and teaching and learning model based on design thinking for pre-service teachers were developed. The developed model conducted a total of three Delphi surveys including expert validation for 6 experts related to education including design thinking, capstone design, was revised, supplemented, and the final draft was confirmed. The final results of this study contain the overall contents of the instructional design, instructor's activities in detailed steps, and guidelines for learners' activities.

The PATROL instructional model only uses digital textbooks. PATROL is an acronym for Planning, Action, Tracking, Recommending, Ordering, and Leading. Teachers have a difficult time using current digital textbooks to determine how much time students spend using course materials. This is because current digital textbooks can only show the content of paper textbooks and display additional multimedia materials. In this study, digital textbook functions were designed based on the PATROL model in order to analyze students' learning situations, diagnose problems, and offer solutions. Digital textbook are based on learning analytics named SEE-PAD. SEE-PAD is composed of the following: Social network analysis; Evaluation and assEssment analysis; Predictive analysis; Adaptive learning analysis; and the analysis Dashboard. I drew and showed the use case and sequence diagrams of SEE-PAD to help design digital textbook functions.

In this study, we carried out a case study with 38 pre-service mathematics teachers. A theoretical basis of this study is the 'technology principle' by NCTM(2000) and teaching-learning methods by the 7th curriculum. Using mathematics program(Grafeq.), we executed classroom activities for developing materials assisting teaching-teaming for 7th-9th grade mathematics. Pre-service mathematics teachers constructed mathematical designs for each grade by Grafeq. program. We tried to find the results for three research problems. On the basis of observation data, interview data and document materials, we analysed our results as follows. First, our activities help Pre-service mathematics teachers to examine and understand each grade mathematics. Second, we can developamathematicaldesignineachgrade mathematics. Therefore mathematical designs developed in this study can be used middle school mathematics classroom. Third, pre-service mathematics teachers gained the belief that the activities using mathematical in this study can be applied program. effectively to teaching and loaming school mathematics.

The purpose of this study is to analyze the teaching and learning strategies included in the inquiry tasks of elementary moral textbooks with multiple intelligences (M.I), and to propose educational information services of teacher librarians. It was found that the tasks were mainly designed by the linguistic intelligence, logical & mathematical intelligence and spatial intelligence. In terms of the information literacy process, linguistic intelligence and spatial intelligence are mainly applied to the analysis-understanding stage. Logical & mathematical intelligence is applied to the stage of comprehensive-application and linguistic intelligence is applied to expression-delivery step. In order to cultivate the insufficient M.I in inquiry activities, teacher librarians should improve room and teaching materials of their school library and provide workbooks using the graphic organizer after analyzing the linkage of the inquiry tasks between the subjects.
