As the demand for AI education increases, AI education is actively conducted in the educational field, but it is difficult to internalize AI education due to securing time, difficulty in organizing class contents, and lack of curriculum. As a way to solve this problem, there is a school autonomous course. The school autonomous course allows schools to have autonomy and discretion throughout the curriculum, such as adjusting the number of hours in the subject group and restructuring the use of achievement standards. In this study, in order to enhance AI education, the effect was analyzed by developing and applying an AI education immersion course using a school autonomous curriculum. In the AI education immersion course, students continuously experience AI education in a dense manner within a limited time, so substantial AI education can be achieved. After the AI curriculum, it was found that students' overall AI literacy and self-determination learning motivation improved. It is expected that this study will be able to present a direction to internalize AI education using school autonomous curriculum.

This study was conducted to provide a solution to the problem of sizing errors occurring in online purchases due to discrepancies and non-standardization in clothing sizes. This paper discusses an implementation approach for a machine learning-based recommender system capable of providing personalized sizes to online consumers. We trained multiple validated collaborative filtering algorithms including Non-Negative Matrix Factorization (NMF), Singular Value Decomposition (SVD), k-Nearest Neighbors (KNN), and Co-Clustering using purchasing data derived from online commerce and compared their performance. As a result of the study, we were able to confirm that the NMF algorithm showed superior performance compared to other algorithms. Despite the characteristic of purchase data that includes multiple buyers using the same account, the proposed model demonstrated sufficient accuracy. The findings of this study are expected to contribute to reducing the return rate due to sizing errors and improving the customer experience on e-commerce platforms.

In this study, we analyzed how information and technology education in elementary and middle school curriculum affects learning achievement of computational thinking courses in university. We conducted a questionnaire survey on students who took computer-related courses for the past year and collected data on what type of computer-related education they received. As a result of analyzing the data, students who received computer-related education in the previous curriculum showed higher overall academic achievement. However, there was a significant difference in learning achievement according to types of contents, and it is necessary to consider the design and improvement of efficient computational thinking education in the future through the results. It is also necessary to continue the analysis of the impact of the new education curriculum.

The main purpose of this research was to discover the characteristics of the 'commons for all' related to public libraries as much as possible, design the learning content, and finally to demonstrate whether the contents meet the general education requirement of universities. The public library is a study hall for multi-literacy, a common place for lifelong learning without discrimination, a place for experiencing digital sharing culture, a place for practicing public architectural design for community regeneration, a workshop for the maker movement and finally, a hub for forming local communities. In short, it has all the characteristics appropriate to being a commons. This subject titled "Sharing Culture and Local Libraries" is designed and composed with various literacy understanding, information ethics of information literacy, community consciousness and multicultural understanding, public consciousness, cooperative spirit and computer utilization ability, interdisciplinary knowledge, and integrated perspective. In a situation where the regional and public crises are increasing, this kind of general education subject about public library, is expected to contribute greatly to raising the awareness of the library and further enhancing the local community togetherness spirit by spreading the value of the library widely to students and inducing them to actually experience various library services.

Mathematical symbolizing is an important part of mathematics learning. But many students have difficulties m symbolizing mathematical ideas formally. If students had experiences inventing their own mathematical symbols and developing them to conventional ones natural way, i.e. learning mathematical symbols via expressive approaches, they could understand and use formal mathematical symbols meaningfully. These experiences are especially valuable for students who meet mathematical symbols for the first time. Hence, there are needs to investigate how early elementary school students can and should experience meaningful mathematical symbolizing. The purpose of this study was to analyze students' mathematical symbolizing processes and characteristics of theses. We carried out teaching experiments that promoted meaningful mathematical symbolizing among eight first graders. And then we analyzed students' symbolizing processes and characteristics of expressive approaches to mathematical symbols in early elementary students. As a result, we could places mathematical symbolizing processes developed in the teaching experiments under five categories. And we extracted and discussed several characteristics of early elementary students' meaningful mathematical symbolizing processes.

Virtual Training generates virtual situation or environment with specific goals in order to instruct trainees as if they are in the real-world. Recently, the demand of experiencing certain incident, which we are not able to experience in real life, has been increased along with the fast developing Virtual Reality (VR) technology. Particularly, Virtual Training(VT) enables us to learn various fields those require high risk and high cost. The system of VT provides interaction and allows us absorb these learning materials better which augments learning effect. Based on the demand of Virtual Training system, this research analyzes current education paradigm National Competency Standards (NCS) in Korea and suggests possible education that utilizes Virtual Training system. At the end of the day, our future goal is to apply suggested Virtual Training contents to universities that reflect NCS curriculum like polytechnic university.

Frequently, pre-service elementary teachers are asked to write reflective journals on their teaching during teacher education program. However, writing reflective journals can not guarantee pre-service teachers to learn from their experience. In this study, 44 reflective journals of pre-service elementary teachers on their science teaching were analyzed in terms of 'productive reflection', a concept suggested by Davis (2006). Productive reflection may help teachers' effective learning by considering interrelationships among aspects of teaching including learners and learning, subject matter knowledge, assessment, and instruction. The result showed what aspects of teaching were included, emphasized, and integrated in the pre-service elementary teachers' reflective journals. Implications for teacher education would be discussed.

The study aimed to investigate what difficulties and needs North Korean refugee college students have in their college English programs and what they experience over an English tutoring program offered by pre-service English teachers. Before the tutoring started, a survey was conducted to examine the current difficulties and needs 100 NK refugee college students had. After the survey, six NK refugee college students and 12 pre-service English teachers participated in the tutoring on the voluntary basis. The survey questionnaires were analyzed statistically, and the effects of the tutoring program were analyzed qualitatively. The results show that NK refugee students reported the severe difficulties in learning English, their increased awareness of the slightly improved English skills over the tutoring program, the increased awareness of their affects, and the increased awareness of their linguistics development at the end of the tutoring. Pedagogical implications for supporting NK refugee college students are discussed.
