The study aims to examine the effectiveness of flipped learning teaching methods by using learning analytics to enable effective programming learning for non-major students. After designing a flipped learning programming class model applied with the ADDIE model, learning-related data of the lecture support system operated by the school was processed with crawling. By providing data processed with crawling through a dashboard so that the instructor can understand it easily, the instructor can design classes more efficiently and provide individually tailored learning based on this. As a result of analysis based on the learning-related data collected through one semester class, it was found that the department, academic year, attendance, assignment submission, and preliminary/review attendance had an effect on academic achievement. As a result of survey analysis, they responded that the individualized feedback of instructors through learning analysis was very helpful in self-directed learning. It is expected that it will serve as an opportunity for instructors to provide a foundation for enhancing teaching activities. In the future, the contents of social network services related to learners' learning will be processed with crawling to analyze learners' learning situations.

In this paper, various platforms are designed, where instructors and students can communicate each other to educate, ask and answer the questions interactivel under the WEB 3-based remote real-time instrurtions. The proposed system maximizes involvements among the students, instrurtors and administrators, which facilitate the understanding and progressive developments of the lessons and tasks to be performed. In the proposed education system, the instructors work as overseers for the study and the students benefit from comparative learning and pattern design. Also, the advantages of WBI are maximized, and the common factors among the mutual components are extracted and reused to avoid the confusion for the students. The advantages of the components are maximized and applied to the proposed system.

This study is design and implementation of diagnosis module using item response theory to assess level of student's knowledge in web-based instruction systems. Item response theory uses responses to items on a test or survey questionnaire to simultaneously locate both the items on the latent trait defined by the set of items while simultaneously scaling each item on the very same dimension. Existing method of measurement in web-based instruction system provided dichromatic learning after to be assess just with the total scores of exam. This measurement has an error that do not consider the level of student's knowledge. Moreover, this method can't perform an exact diagnosis of student knowledge and make student modeling to construct intelligent tutoring system. In this study, we present that design and implement a diagnosis module using item response theory to assess level of student's knowledge in web-based instruction systems

As the society evolves into information age, new teaching and learning methods are proposed. In this paper, we design and implement an on-line quiz program for the formative evaluation of Distance Computer Education. The computer studies include many difficult concepts and those are hard to learn and the distance learning has the advantage of overcoming time and spatial limitations but it needs learner's strong motivations to study. Also, the formative evaluation may guide teachers and learners to studying course and it is necessary to prevent both users from too much load. Therefore, presenting quiz and solving it may be a better way for the formative evaluation and we design and implement a Quiz Program for the formative evaluation of Distance Computer Education. We believe that our program will improve motivation of students in Distance Computer Education

The purpose of this study was to identify the relationship of instructional design, perceived learning transfer, and satisfaction. The data were collected using questionnaire from the sample of 239 nursing students. The level of learning transfer was explained by introduction with learning context & providing guidance and initial attention. The level of learning transfer was explained by learning object with motivation, learning goal alignment, accessibility and feedback & adaptation. The level of program satisfaction was explained by introduction with learning context & providing guidance and initial attention. The level of program satisfaction was explained by learning object with motivation, presentation design, interaction availability, feedback & adaptation, learning goal alignment and contents quality. The findings serve as basic data to design e-Learning program to improve learning transfer and satisfaction.

The purpose of this study is to investigate differences in learning flow and teaching presence according to the lecturer's appearance and the lecturer's speech rate. For this experiment, 183 freshman students from Xingtai University in China were selected as subjects of the experiment, and a total of four types of lecture videos were developed to test the lecturer's appearance and their speech rates. Data was analyzed through multivariate analysis of variance. According to the results of the analysis, first, learning flow and teaching presence of groups who experienced the presence of the lecturer appeared were significantly higher than the groups who learned without the appearance of the lecturer. Second, the groups who learned from videos with a fast speech rate showed higher learning flow and teaching presence than the group who learned at a slow speech rate. Third, there were no significant differences in both learning flow and teaching presence according to the lecturer's appearance and speech rate. This result provides a theoretical and practical basis for developing customized videos according to learners' characteristics.

컴퓨터 네트워크의 발전에 의해 학습 공간의 시공간적인 확대와 교육 현장에서 교수-학습 과정에 대한 새로운 교수방법을 요구되었고, 유무선 방송, 인터넷 등을 이용하여 다양한 형태의 원격교육이 구체화되어 왔다. 하지만, 현재 운영되는 대부분의 원격교육시스템은 실질적인 학습 상황에서 단방향적인 개별 학습 형태를 보이고 있고, 사용자간의 쌍방향 상호작용을 위해서는 교수자나 학습자에게 일정 수준이상의 기술적 소양과 경제적 부담을 요구한다. 또한 교수자에게는 교수-학습 상황에서 발생하는 학습자 행동에 대한 실시간적인 모니터링과 학습자의 학습과정에 대한 평가의 어려움을, 학습자에게는 자기 반성의 기회를 제대로 제공하지 못하는 문제점을 안고 있다. 이에 본 연구에서는 원격교육에서의 협동학습 지원, 사용자의 기술적, 경제적 부담의 제거, 학습 전(全) 과정에 대한 원활한 모니터링과 피드백 기회의 제공을 목적으로 원격협동학습 시스템을 설계하고, 이를 개발하였다. 본 연구에 의해 개발된 원격협동학습 시스템은 원격협동학습을 지원하는 네트워크 화이트보드, 학습 과정 및 결과를 자연어로 저장하는 저장 모듈, 그리고 저장된 학습 스크립트 파일을 해석하여 재생하는 스크립트 인터프리터로 구성되었다. 네트워크 화이트보드는 소프트웨어적으로 구현되어 부가적인 장치가 불필요하고, 통신 서버를 분산하여 서버 구축에 대한 부담을 제거하였고, 학습 내용 화면을 대화창으로 사용하여 사용자의 사용 편리성을 제고하였다. 또한 원격학습의 장(場)에 교수자가 참여하여 실시간적 모니터링이 가능하고, 학습의 전(全) 과정 및 결과를 저장한 자연어 스크립트 파일에 의해서도 학습자 행동에 대한 모니터링이 가능하다. 저장된 자연어 스크립트 파일은 구현된 인터프리터를 이용한 재생뿐 아니라, 파일 자체만으로도 학습과정을 판독할 수 있고, 스크립트 파일에 대한 해석은 교수자에게는 학습자의 학습 과정에 대한 평가 및 피드백의 근거를, 학습자에게는 자신의 학습 행동에 대한 반성의 기회를 제공한다. 본 시스템은 기존의 원격교육시스템에 비해 장비 및 인터페이스 측면에서 간소화되었고, 원격교육에 면대면 학습 개념을 근사적으로 접목시킨 교수 모델로서의 충분한 가치를 제공하나, 실제적인 학습 적용과 효과에 있어서의 타당성은 차후 검증이 있어야 하고, 또한, 이에 따른 시스템에 대한 지속적인 보완도 필요하다.

This paper studies VPBL(Various PBL) models, applies them to classes, and analyzes results so that students of various majors can design and implement problems according to the characteristics of their majors in order to improve problem solving in education. VPBL performs the process of designing and implementing problems that reflect the characteristics of the major by applying constraints to the professor's programming language. The professor performs mini_class in the process of solving the designed problem and then shares it throughout. VPBL model apply results, The traditional teaching method was 3.51 points and the application of the VPBL model was 4.52 points, and "interaction, understanding of learning contents, and acquiring knowledge related to curriculum" were improved. In addition, VPBL has the advantage of expanding the learning range in the solving process as it is based on various problem solving, which has the effect of expanding the learning range compared to existing class models. Research on the expanded application of various SW liberal education in the future is required.
