학습자의 감성 상태가 충분히 반영되는 오프라인 수업과 달리 지금까지 대부분의 e-러닝은 학습자의 감성 정보를 수업에 효과적으로 반영하지 못했다. 이러한 한계점은 e-러닝의 학습 효과성을 저해하는 문제 중 하나로 지적되었다. 이 문제를 해결하기 위해 학습자의 뇌파를 통해 감성을 인식하고 감성 상태에 따라 적절한 학습 콘텐츠 타입을 추천하여 학습 효과를 증대 시킬 수 있는 방법론이 주목을 받고 있다. 본 논문에서는 기 수집된 학습자들의 감성(뇌파) 데이터를 분석하여 콘텐츠 타입 선호도를 파악한 후 프로파일 데이터를 활용하여 상관계수 기반 NN-Recommendation 학습 콘텐츠 타입 추천 시스템을 제안 하고자 한다. 이 시스템은 일반적인 추천시스템에서 발생하는 Cold-start 문제를 해결할 수 있으며 특히 본 연구에서는 보다나은 추천 정확도를 위해 프로파일 각 속성에 자동적으로 가중치를 부여하는 기법을 제시하여 향상된 성능을 보이게 됨을 실험을 통해 확인 하였다.

The purpose of this study is to identify the difficulties of learners who started programming after entering college and to search an effective software education method as university liber arts for non-science major students. In order to do this, we analyzed the difficulties of learners in Python programming classes composed of students from various majors at H University through questioning and taught them using flipped class model with pre-questions. The questions that students submit are collected online before class every time, the data on the degree of the difficulty of feeling and the understanding of feeling were obtained through the questionnaire. As a result, for learners who are new to programming, the learners should allocate the process of making the problem into a logical abstraction at the beginning of the curriculum before learning the basic concept of computer language, each lesson should be practiced through the bottom-up problems enough to provide a logical understanding before actual coding. In addition, detailed curriculum should be developed according to characteristics of learner's major, contents and conducting level.

The concept of 'Edu-Tech', which is rapidly reorganized around e-Learning, has been spreading along with the development of intelligent information technology according to the fourth industrial revolution such as Artificial Intelligence (AI), Internet of Things (IoT), BigData. Currently, leading companies are conducting online education services, but real-time two-way communication is difficult. In addition, in the case of off-line class, there are many students, and not only the time is limited, but also they often miss the opportunities to ask questions. In order to solve these problems, this paper develops a real - time interactive question and answer management system that can freely questions both on - line and off - line by combining the benefits of offline instant answers and the advantages of online openness. The developed system is a real-time personalized education system that enables the respondent to check the situation of the questioner in real time and provide a customized answer according to the inquirer's request. In addition, by measuring and managing the system usage time in seconds, the questioner and the respondent can efficiently utilize the system.

Although the e-learning system is being introduced in elementary and secondary education, incorporating it into the regular curriculum is difficult. Other problems include the lack of sessions and connection to regular courses in realistically applying project-based learning in the regular school curriculum. Therefore. this study established, applied, and analyzed the blended learning strategy to resolve such issues. Specifically, a theoretical investigation on the concept of blended learning and IT-oriented, project-based learning was conducted. The theme for learning based on integrated courses was also selected, and the 5-stage project-based teaching and learning strategy, concretized. The concretization strategy involved discussion, role division, and alternative evaluation strategy. The class progressed in formats of on-class online, on-class offline and off-class online. As a result, students experienced inconvenience since the project only lasted for a short period of time. Nonetheless, they responded positively to the effect of project-based learning in general. This study was able to suggest the possibility of applying e learning in regular school curriculum and propose the direction for digital and learner oriented teaching.

Applying iterative learning utilizing SNS & Community to the class for pre-kindergarten teachers, the effectiveness of teaching satisfaction, self-efficacy, and curriculum understanding was verified. A iterative learning model utilizing SNS & Community in teachers leading traditional off-line teaching at college education field was applied separately into thinking to one-self by advance organizer, thinking together by presentation in the beginning of the class, and sharing the thoughts by community activities after the class. Iterative learning begins by being sent SNS to students from teachers before the class, but learners for themselves subsequently start to proceed self-directed learning activities. As a result, class satisfaction and understanding of pedagogy have been increased, and it had a positive influence on self-efficacy. Thus, it is to suggest utilizable SNS of professors and a teaching method utilizing Community to college students who need basic learning skills.

Novel Engineering(NE) is integrated learning model to figure out problems in a book and solve them with creative engineering process. NE has been performed on offline until now. We have to research blended learning projects for COVID-19 outbreak. In this paper, we are going to explore that blended NE is effective to creative problem solving ability. The results showed that blended NE is highly effective to all of four sub-elements; self conviction & independence, diffusion thinking, critical thinking and motivational element. This means that blended novel engineering class is effective to competence-centered class proposed in 2015 revised curriculum. We hope that the research is spread and settled into our school.

This study is intended to analyze flipped classroom learning activities, which have recently been spotlighted as a learner-centered teaching method in universities, from the perspective of cultural and historical activity theory. A survey and some participation observations were conducted with one professor and the students who participated in Educational Methods and Technology courses at A university. The components of the flipped classroom learning activities were analyzed based on the model of the activity system, and contradictions that appeared in the interactions between components were analyzed. Four implications were proposed for a more advanced flipped classroom learning activity system: the professor's and the learners' true identity recognition and role performance, strengthening the organic link between online and offline activities, support for alleviating the burden of teaching and learning preparation, and readjusting the system to support its smooth operation.

This study is investigating the effectiveness of a blended learning for English listening and reading class by analyzing students' learning behavior. To this end, two surveys were conducted on a total of 75 students from the two different classes of Academic English Listening and Reading course. The research results showed that in the online class, the students built undesirable learning behavior such as solving listening quizzes by reading listening scripts or watching the instructor's lectures about the scripts and completing the assignment of summary of the scripts by referring to the Korean versions. In the offline class, the students' participation in group activities and attention to lectures was good. Therefore, it can be concluded that because of the students' poor online learning behavior, this blended learning was rather not effective. So the suggestions are discussed to enhance the effectiveness of the blended learning for English listening and reading.
