This paper sought to find significant learning behavioral indicators and their correlation with the academic achievements of elementary teacher candidates engaged in an online course using MS Teams during the COVID-19 pandemic. Focused on variables such as the number of visiting days to MS Teams, on-time online assignments, conversation activities, posts, and replies, MS Insights data in the LMS environment were collected in the fall term of the 2020 academic year and analyzed in Pearson correlation and multiple regression. The number of visiting days and on-time online assignments were significantly correlated with their grades, whereas the indicators including average weekly conversation activity, posts, and replies did not have a significant effect on the achievements. Furthermore, the results revealed that the subject's behavioral intention to submit on-time assignments significantly predicted learner achievements.

본 연구에서는 사이버가정학습을 교사가 교실 수업과 사이버가정학습 시스템을 연계하여 운영함에 있어 어떤 요인이 사이버가정학습에 대한 학습자 만족에 영향을 미치는지를 분석하였다. 기술수용모형을 기반으로 Y초등학교 5학년 학생들을 대상으로 6개월간 운영한 후 설문조사를 실시하였다. 분석결과 초등학생들에게 사이버가정학습 만족도는 지각된 유용성과 용이성에 의하여 결정되는 것으로 나타났으며, 자기주도적 학습 능력과 학습결과보상기능은 사이버가정학습을 긍정적으로 수용할 수 있는 유용성에 상당한 영향을 미치는 중요한 요인으로 작용하는 것으로 분석되었다. 만족도에 영향을 미칠 것으로 예상했던 교육적 효과, 콘텐츠 품질은 만족도를 직접적으로 유발시키는 본질적인 요인이 아님을 알 수 있었다. 학습지원기능, 시스템 안정성 및 편리성, 상호작용 등 시스템적인 기능이 만족도에 유의미한 영향을 미치지 못하는 것으로 나타났다. 이 요인들은 단지 콘텐츠의 품질을 향상시키는 효과를 가지며, 이 효과를 통해 교육적 효과를 강화시키는 역할을 수행하는 것으로 분석되었다. 따라서 학습을 지원하는 기능, 시스템 안정성 및 편리성, 선생님과 학생 또는 학생 간의 상호작용이 가능하도록 지원하는 모든 시스템적인 기능은 수강생의 만족도에 직접적인 영향을 미치거나 만족을 이끌어 낼 수 있는 본질적이고 핵심적인 요인이 아님을 알 수 있다.

The purpose of this study is to help to improve the method of math teaching by analysing how learner-centered teaching method offsets mathematical creativity and mathematical disposition. For this purpose, research questions are established as follows; (1) Mathematical creativity between open-ended learning activity approach(OLAA) and general classroom-based instruction(GCI) shows any difference? (2) Mathematical disposition between OLAA and GCI shows any difference? The results obtained through this study were as follows: (1) There was significant difference between OLAA group and CCI group in mathematical creativity. This means that open-ended learning activity approach was generally more effective in improving mathematical creativity than general classroom-based instruction. (2) There was no significant difference between OLAA group and GCI group in mathematical disposition. But the average scores of mathematical disposition except mathematical confidence improved a little. So we can say that open-ended learning activity approach brought an positive influence on students' mathematical disposition. The results obtained in this study suggest that the OLAA can be used to cultivate the children's mathematical creativity and disposition. Therefore, I suggest that teachers should use the OLAA to improve the children's mathematical creativity and disposition.

The representative branch of ICT education is Arduino. However, there are various problems when teaching using Arduino. Arduino requires a complex understanding of hardware and software, and this can be perceived as a difficult course, especially for beginners who are not familiar with programming or electronics. Additionally, the process of connecting the pins of the Arduino board and components must be accurate, and even small mistakes can lead to project failure, which can reduce the learner's concentration and interest in learning Arduino. Existing Arduino learning content consists of text and images in 2D format, which has limitations in increasing student understanding and immersion. Therefore, in this paper analyzes the necessary conditions for sprouting 'growing kidney beans' in the first semester of the fourth grade of elementary school, and builds an automated experimental environment using Arduino. Augmented reality of the pin connection process was designed and produced to solve the difficulties when building an automation system using Arduino. After 3D modeling Arduino and components using 3D Max, animation was set, and augmented reality (AR) content was produced using Unity to provide learners with more intuitive and immersive learning content when learning Arduino. Augmented reality (AR)-based Arduino learning content production is expected to increase educational effects by improving the understanding and immersion of classes in ICT education using Arduino and inducing fun and interest in physical computing coding education.

This paper aims to develop a map for optimized class space using ZEP among the metaverse platforms. As a research method, the classroom space was organized so that the subject of learning became a learner, and the classroom space was modified and supplemented to optimize while being applied to elementary school computer classes. The contents of the study investigated learners' prior perception of metaverse, and compared and analyzed the advantages and disadvantages of the metaverse platform. In addition, the map was designed by reflecting the results of the survey, and after applying the map to the class, necessary APIs and apps were installed to supplement it. As a result, the learner became the subject of learning in the metaverse space, freely identified the space, and actively participated in the class. In particular, we found that students who were passive offline and those who had a low participation rate due to lack of skills participated more actively. In particular, students who were passive offline or whose participation was low due to lack of skills participated more actively. If API and JavaScript programs are added to collect log data of learners for learning analysis, real-time feedback is possible for learners, and learner feedback is possible for instructors with statistical data. If this is possible, the metaverse space can fully expect the role of a learning assistant for learners and a teaching assistant for instructors.

With the active utilization of Online Judge (OJ) systems in the field of education, various studies utilizing learner data have emerged. This research proposes a problem recommendation based on a user-based collaborative filtering approach with learner data to support learners in their problem selection. Assistance in learners' problem selection within the OJ system is crucial for enhancing the effectiveness of education as it impacts the learning path. To achieve this, this system identifies learners with similar problem-solving tendencies and utilizes their problem-solving history. The proposed technique has been implemented on an OJ site in the fields of algorithms and programming, operated by the Chungbuk Education Research and Information Institute. The technique's service utility and usability were assessed through expert reviews using the Delphi technique. Additionally, it was piloted with site users, and an analysis of the ratio of correctness revealed approximately a 16% higher submission rate for recommended problems compared to the overall submissions. A survey targeting users who used the recommended problems yielded a 78% response rate, with the majority indicating that the feature was helpful. However, low selection rates of recommended problems and low response rates within the subset of users who used recommended problems highlight the need for future research focusing on improving accessibility, enhancing user feedback collection, and diversifying learner data analysis.

This study aims to develop the NABI program, which can be applied to science education in school, to realize 'Science Education through Nature' for today's students. The first NABI program was developed based on the viewpoints of education and teaching methods of Nature-Study, and it was revised as the second NABI program through experts' workshop. The second NABI program was applied to 24 third-grade students of an elementary school. The possibility of applying the program to school science education was explored through the analysis of students' qualitative data, along with surveys that were completed by 24 students and 79 current teachers. As a result of applying the program, students were curious about and communed with nature. The program could also realize the learner-centered education and integration of subjects, science with literature and art. The students were interested and wanted to continually participate in the NABI program. The teachers' evaluation of the program deduced that the relationship between the program presenting Nature-Study ideologies could be applied to science education in school. In conclusion, it was found that the NABI program was well reflected in the scope of the Nature-Study, and it can be applied to science education in school. The NABI program proceeds in nine steps: 'Accepting - Choosing - Selecting the common subject - Ice Breaking - Making relationship - Observing - Scaffolding - Expressing - Sharing'. The NABI program is a good way to realize the essence of science education, 'Science Education through Nature', for today's students.

In order to adapt ourselves to the Informationalization Society of twenty-first century, it is required to have ability to find quickly the necessary information and solve the problem of our own. In the field of school, it should be educated to develop learner's ability that can cope with the Informationalization Society. When a learner can study in such direction, he or she will be able to plan the learning of his own as the subject of education, and develop his ability to solve the problem by collecting and examining various information. It is self-leading learning that can make education like this possible. Through computer, especially Web site, self-directed learning can develop can develop the individuality and creativity of learners. They can collect and utilize autonomously information and knowledge. To do such an education, the program that can work out self-directed learning is needed. Therefore the program I want to develop is to reconstruct the 'figure' part of mathematics in elementary school into five steps by utilizing Web site. In the first step is to learn the concept of various shape. This step enable learners to know what figure is and how it can be utilized in our real life. The second step of dot, line and angle makes it possible that learners can consolidate the foundation of the study about figure and recognize the relation between angle and figure. In the third step of plane figure, we can study how to calculate the relation of plane figures and the area of figure with various shapes by cutting and adding them. The fourth step is about congruence and symmetry. Learners can learn to know the figure in congruence, reduction and enlargement and how it is used in our real life. In the fifth step of solid figure, we can learn the relation among the plane figure, solid figure, the body of revolution, corn and pyramid etc. controling the speed of learning on the basis of his ability. In the process of the program, it is also possible to develop learner's ability of self-leading learning by solving the problem by himself. Because this program is progressed on the Web site, it is possible to learn anytime and anywhere. In addition to it, a learner can learn beyond the grade as well as do the perfect learning by controling the pace of learning on the basis of his ability. In the process of the program, it is also possible to develop learner's ability of self-leading learning by solving the problem by himself.
