This study aims at developing and evaluating the cohousing teaching/learning plan for middle and high school. The plan was developed into 5 stages such as data collection and analysis, design, development, implement, and evaluation_ It was composed of 3 lessons with various teaching materials; the concept and necessity of cohousing, spatial composition, and making a cohousing village as the main theme. The 3 home economics teachers carried out the plan for 28 classrooms (1125 students) in 2 middle and I high school, during 23th, Aug., to 17th, Sep. 2010 in Kyunggido. The high level of understanding, learning processes, interest, satisfaction with the class reported by the students showed that the plan might be adequate to both high and middle school students. The teachers carried the lessons reported the similar positive responses to the plan with some suggestions to increase teaching hours, prepare class appliances, and prepractice the teaching materials.

최근 데이터의 양이 많아지고 다양해짐에 따라서 데이터를 활용하기 위한 데이터 마이닝에 관한 관심이 중대되고 있다. 데이터 분석을 위한 수집 데이터에는 수집 과정에서 분석가가 원치 않은 데이터 잡음이 발생하는 경우가 있고 그 데이터가 다른 데이터들과 같은 가중치로 데이터 마이닝에 반영되는 경우 예상과 다른 결과를 얻을 수 있다. 따라서 데이터 분석 시 데이터와 전문가 의견이 고려된 데이터 엔트로피(Entropy)를 사용하여 잡음 데이터를 다를 필요가 있다. 본 논문에서는 전문가의견을 이용한 전문가 의견 목록을 만들고 이를 데이터와 비교하여 유사한 정도에 따라 각 데이터에 가중치를 부여한다. 그리고 이 데이터를 활용한 의사결정나무(Decision Tree)를 사용하여 기존 데이터를 이용한 의사결정나무 보다 데이터 잡음의 영향을 줄이는 방법을 제안한다. 제안한 방법은 학습자의 학습 활동에서 수집된 학습 행위 데이터를 사용하여 실험하였다.

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.

Algorithm education is emphasized as an instrument for teaching the basic principles of Computer Science. But these materials is very short-fall. We'll present the CS Unplugged-based algorithm contents, which is easy to learn for elementary student. These contents for self-directed learning consisted of the activity-based learning. For problem-solving algorithm learning in everyday life we were developed the hashing techniques on the basis of the basic searching and sorting algorithms. For checking the adequacy of these materials were tested by surveys of teacher professional groups, and we obtain the appropriate conclusions for sorting algorithm contents for improving the problem-solving ability for in elementary student.

The purpose of this study was to develop an AI liberal arts subject for pre-service teachers of all majors in elementary and middle school. To this end, the main areas of the AI curriculum, sub-themes for each week, and activities were specifically designed and verified through two rounds of Delphi by 13 experts. The AI liberal arts curriculum in this study consists of three areas. Then, detailed topics for each week were confirmed, and a total of 13 weeks were arranged according to the natural flow. It was intended to help teaching and learning by arranging learning activities based on the experiential learning model according to the learning content. It is expected that this study will be used as basic data for the development of various AI education subjects for pre-service teachers in elementary and secondary schools in the future.

The purpose of this research is to provide a desirable case of STEAM education utilizing 'Energy and Transportation Technology' unit on the subject of technology home economics. The middle school students learned with the integrated approach based on STEAM integrated education, and through production process they had the opportunity for application and expression in diverse forms. The results of this process to achieve the purpose are as follows. First, as the procedural model to develop STEAM program utilizing 'Energy and Transportation Technology' unit on the subject of technology home economics, the five stages: preparation, development, verification, practice, and evaluation, were presented. The preparation stage was composed of requirement analysis, the selection of program subject, and STEAM program curriculum analysis, the selection and organization of STEAM program lesson. The development stage was composed of the development of lesson plan, multimedia teaching materials, worksheet and worksheet answer key. In the verification stage, the verification of validity by experts was conducted, and in the practice stage, the developed program was applied to the middle school students in the educational field, and in the evaluation stage, based on the evaluations received from learners and teachers, it was revised and supplemented. Second, the STEAM program was developed into the program summary map, lesson plan, multimedia teaching materials, worksheet and worksheet answer, etc., and after the validity was secured through experts' verification, it was revised and supplemented and applied to actual classes. Third, the results of the learners' evaluation of the developed STEAM program showed that the degree of satisfaction with the program was high with the average score of the entire questions being 4.00 on a five-point scale. As the teachers also evaluated the developed STEAM program as very effective, the opinions of learners and teachers were collected and the program was finally improved and completed.

The deterioration of facilities is an unavoidable phenomenon. For the management of aging facilities, cracks can be detected and tracked, and the condition of the facilities can be indirectly inferred. Therefore, crack detection plays a crucial role in the management of aged facilities. Conventional maintenances are conducted using the crack detection results. For example, maintenance activities to prevent further deterioration can be performed. However, currently, most crack detection relies only on human judgment, so if the area of the facility is large, cost and time are excessively used, and different judgment results may occur depending on the expert's competence, it causes reliability problems. This paper proposes a concrete crack detection framework based on machine learning to overcome these limitations. Fully automated concrete crack detection was possible through the proposed framework, which showed a high accuracy of 96%. It is expected that effective and efficient management will be possible through the proposed framework in this paper.

The purpose of this study is to develop a flipped-learning based education model for vocational education and training. Based on previous studies, we have developed a training model that includes definitions of flipped-learning, major learning activities, and operational strategies in each occupation. In addition, delphi surveys were carried out to confirm the validity of the educational model for HRD and vocational education and training specialists. Finally, the flipped-learning model for vocational education and training consists of three stages: Pre-learning, Main-learning, and Post-learning. Pre-learning stage include Online lectures, Simple tasks, Main-learning stage include Active learning and Coaching-Debriefing lecture, Post-learning stage includes Individual reflection-Additional task performance activities. The educational model developed through this study was developed with the focus on improving the linkage and the performance of the goal of vocational education and training.

본 연구는 대학교육에서 학습자 주도수업에 대표적으로 활용되는 PBL-교수학습방법을 SNS기반 온라인 플랫폼에서의 과제수행을 통해 해결하는 PBL-수업모형을 개발하는 것을 목표로 한다. 이를 위해 선행연구 및 이론탐색을 통해 PBL-수업설계에 대한 선행연구를 고찰하고, 적용 가능한 수업모형 및 교육내용을 선정하여 기초내용을 구성한 후 3인의 교육공학 전문가와 5인의 대학교수를 대상으로 FGI 인터뷰 방법을 통하여 연구결과를 도출한다. 과거 PBL-교수학습방법을 적용한 수업설계 들이 모의수행이나 발표 후 토론에 한정되었던 것에 반해 본 연구에서는 SNS기반 온라인 플랫폼에 직접 적용하는 매체제작 및 커뮤니티 활동을 포함하는 수업활동이 도출 되었으며, 실행 가능한 수업모형 개발을 위해 대상자 인터뷰와 분석을 통해 이를 위한 교수학습방법을 설정할 것이다. 본 연구를 통해 제시될 SNS기반 온라인 플랫폼을 활용한 PBL-학습모형은 이후 고등교육기관의 교수학습모형 개발을 위한 기초자료로 활용될 것이다
