학교 교실에서의 수업 활동 중 가장 주된 활동은 언어적 의사소통이며 대부분의 지식 전달이 교사의 언어 활동을 통해 이루어 지고 있다. 그리고 교사의 언어적 의사소통의 순서와 구조는 효과적이고 효율적인 학습에 중요한 의미를 가지므로 이를 조직적으로 분석 평가할 필요가 있다. 따라서, 이 연구는 교실에서의 교사 언어 행동의 구조를 분석 연구할 수 있는 방법론적 기초를 마련하고자 Anderson 의 역동적 구조 이론 (Theory of Kinetic Structure) 을 소개하고, 그의 정량적 분석 방법을 한국어에 적용 할 수 있도록 수정하였으며, 교사의 실제 강의 내용을 분석하였다. 분석에 사용한 자료는 50분 동안 진행된 고등학교 1학년 생물 강의를 녹음한 것으로 소화에 관한 내용이었다. 강의 내용에서 역동적 구조의 정량적 분석 결과는 다음과 같다. 강의는 316개의 담화단위 (discourse units) 로 구성되었으며. 261개의 어소 (verbal elements)가 동정되었다. 전체 강의에서 37개의 secondary span 이 동정되었고 이는 6개의 primary span으로 구분되었다. 전체 강의에 대한 평균 기본계수(mean fundamental coefficient, $\bar{B}_1$)는 0.26으로 낮은 수준의 연관도 (commonality )를 보였으며, 평균 가중 기본계수(mean weighted coefficient, $\bar{B}_2$)의 값은 0.88이었다. 전체적으로 이 강의는 중 내지 하 구조 (moderate to low structure)를 갖고 있으며, 높은 진행도 (high progression, $\bar{D}_s$=1.07)를 보였다.

Many kinds of the education systems are provided to students. Many kinds of the contents like School subjects, license, job training education and so on are provided through many kinds of the media like text, image, video and so on. Students will apply the knowledge they learnt and will use it when they learn other things. In the existing education system, there have been many situations that the education system isn't really helpful to the students because too hard contents are transferred to them or because too easy contents are transferred to them and they learn the contents they already know again. To solve this phenomenon, a method that transfers the most proper lecture contents to the students is suggested in the thesis. Because the difficulty is relative, the contents A can be easier than the contents B to a group of the students and the contents B can be easier than the contents A to another group of the students. Therefore, it is not easy to measure the difficulty of the lecture contents. A method considering this phenomenon to transfer the proper lecture contents is suggested in the thesis. The whole lecture contents are divided into many lecture modules. The students solve the pattern recognition questions, a kind of the prior test questions, before studying the lecture contents and the system selects and provides the most proper lecture module among many lecture modules to the students according to the score about the questions. When the system selects the lecture module and transfer it to the student, the students' answer and the difficulty of the lecture modules are considered. In the existing education system, 1 kind of the content is transferred to various students. If the same lecture contents is transferred to various students, the contents will not be transferred efficiently. The system selects the proper contents using the students' pattern recognition answers. The pattern recognition question is a kind of the prior test question that is developed on the basis of the lecture module and used to recognize whether the student knows the contents of the lecture module. Because the difficulty of the lecture module reflects the all scores of the students' answers, whenever a student submits the answer, the difficulty is changed. The suggested system measures the relative knowledge of the students using the answers and designates the difficulty. The improvement of the suggested method is only applied when the order of the lecture contents has nothing to do with the progress of the lecture. If the contents of the unit 1 should be studied before studying the contents of the unit 2, the suggested method is not applied. The suggested method is introduced on the basis of the subject "English grammar", subjects that the order is not important, in the thesis. If the suggested method is applied properly to the education environment, the students who don't know enough basic knowledge will learn the basic contents well and prepare the basis to learn the harder lecture contents. The students who already know the lecture contents will not study those again and save more time to learn more various lecture contents. Many improvement effects like these and so on will be provided to the education environment. If the suggested method that is introduced on the basis of the subject "English grammar" is applied to the various education systems like primary education, secondary education, job education and so on, more improvement effects will be provided. The direction to realize these things is suggested in the thesis. The suggested method is realized with the MySQL database and Java, JSP program. It will be very good if the suggested method is researched developmentally and become helpful to the development of the Korea education.

Recently, the form of education has changed from one-way to two-way and mutual exchange rather than the existing one-way order form, and accordingly, it is necessary to consider creating a suitable learning environment for each type of education. The basic form of education consists of the delivery of knowledge, that is, the delivery of knowledge by teachers to education consumers through voice delivery, so the sound environment is considered an essential factor in creating a pleasant learning environment. The indoor sound environment is very closely related to the mental stress of the inmate, so the quality level of education will also change greatly depending on whether or not the appropriate sound environment is created. However, the importance of the sound environment in educational facilities such as classrooms has not been highlighted due to the lack of research and related laws on the sound environment. Therefore, in this study, auditory tests were conducted using the auralization based on the physical acoustic performance data presented in the preceding study. Through this, we wanted to verify the validity of this research by analyzing the subjective acoustic performance satisfaction of the occupants due to the improvement of the physical acoustic performance. Based on these research results, it is estimated that the improvement of the sound environment of educational facilities through remodeling in the future will be possible to verify whether the sound environment suitable for educational facilities is created only after the analysis stage on the improvement of subjective sound performance as well as physical sound performance.

Severe Acute Respiratory Syndrome is being impacted worldwide by the prolonged COVID-19 situation. Due to the impact of COVID-19, domestic educational institutions have also changed their teaching methods. Domestic universities traditionally aim for face-to-face lectures, but due to the pandemic, they are conducting non-face-to-face lectures. This study aims to evaluate the effect of non-face-to-face lectures on radiology students. The subjects of this study are students of the Department of Radiology at University D in Daegu. As for the contents of the study, satisfaction with non-face-to-face lecture delivery, concentration, and comprehension was evaluated. Data analysis was performed in SPSS Ver. 26 was used, and the reliability measurement was found to be Cronbach's alpha coefficient = 0.805. In the results of this study, the satisfaction of non-face-to-face lecture delivery, concentration, and comprehension was overall high. However, satisfaction with theoretical subjects (2.08±0.88) was significantly different from that of practical subjects (2.51±1.10) (t=-9.880, p<.001). Satisfaction by grade level was highest in the first grade. As a result, it is judged that non-face-to-face theoretical lectures require more careful preparation from lecture planning than practical lectures, and further research is expected in the future.

지식ㆍ정보화 사회에서는 교사가 학생에게 교과서의 지식뿐만 아니라, 학생 스스로 인지 구조를 형성할 수 있도록 다양한 정보를 제공해야 한다. 따라서, 동일한 교과를 강의하는 교사들은 웹 상의 대량의 정보 가운데서 의미 있는 정보를 서로 교환ㆍ공유하여 교수-학습활동에 활용할 필요가 있다. 기존 웹 상의 교수-학습자료 시스템은 주로 HTML을 이용하기 때문에 한정된 태그만을 사용하여 사용자가 원하는 형태의 기능을 지원할 수 없을 뿐만 아니라 이런 태그들은 정확한 의미를 전달하지 못한다. 또한 구조화 능력이 부족하여 문서의 계층 구조를 표현하지 못하며, 효과적인 저장과 검색이 불가능하다. 즉, 화면상에 보여지는 기능 외에는 색다른 기능을 제공하지 못한다. 본 논문에서는 동일한 교과를 강의하는 교사가 교수-학습자료를 웹 상에서 손쉽게 작성하여 원활하게 교환할 수 있도록 XML 문서로 생성하는 시스템을 설계 및 구현한다. XML 문서의 교수-학습자료는 의미 있는 정보 전달과 문서의 구조화가 가능하다 또한 데이터를 수정하는 기능과 다양한 표현 형식이 가능하도록 지원함으로써 기존의 교수-학습자료의 재사용을 가능케 한다. 결과적으로, 교사가 교수-학습자료 작성에 드는 시간과 노력을 절약하여 본연의 임무에 충실하도록 해줌으로써 교수-학습활동의 질을 향상시킬 수 있다.

The purpose of this study is to define On-line Video Syllabus Template which is based on adaptive mode with interaction.A syllabus has the significance as a teaching and learning plan. However, it has not only been considered as a formal document, has also been limited into a simple query since it has been made into a fragmentary structure, lacking of link between other services and reuse. Additionally, this paper is aimed to design three-dimensional syllabus which makes it possible to provide students with practical information related to teaching and learning and share it with teachers and students. The following is the technique proposed in this paper. It is made to be served for the Syllabus centered on teaching and learning, which is including the definition of hierarchy structure, the media contents application according to the learner's preference and real-time variation function. On-line Video Syllabus provided through LMS has availability and credibility of teaching and learning, in that it enable increased utilization by strengthening convenience.
