In this article, the author's intent is to begin a conversation centered on the question: How was the integration of digital technology into elementary mathematics classrooms framed? In the first part of the discussion, the author provides a historical perspective of the development of theoretical perspectives of the integration of digital technology in learning mathematics. Then, the author describes three theoretical perspectives of the role of digital technology in mathematics education: microworlds, instrumental genesis, and semiotic mediation. Last, based on three different theoretical perspectives, the author concludes the article by asking the reader to think differently.

Developing from stereoscopic to autostereoscopic, researchers on display technology are trying to provide more depth cues to viewer, leading to the advent of true 3D display. Volumetric 3D displays seem to be practical technology at present. Ultimate display will function like human vision system, with characteristics of providing all depth cues and free interaction.

2D/1D coupling method is an important neutron transport calculation method due to its high accuracy and relatively low computation cost. However, 2D/1D coupling method may diverge especially in small axial mesh size. To analyze the convergence behavior of 2D/1D coupling method, a Fourier analysis for k-eigenvalue neutron transport problems is implemented. The analysis results present the divergence problem of 2D/1D coupling method in small axial mesh size. Several common attempts are made to solve the divergence problem, which are to increase the number of inner iterations of the 2D or 1D calculation, and two times 1D calculations per outer iteration. However, these attempts only could improve the convergence rate but cannot deal with the divergence problem of 2D/1D coupling method thoroughly. Moreover, the choice of axial solvers, such as DGFEM SN and traditional SN, and its effect on the convergence behavior are also discussed. The results show that the choice of axial solver is a key point for the convergence of 2D/1D method. The DGFEM SN based 2D/1D method could converge within a wide range of optical thickness region, which is superior to that of traditional SN method.

What is the term "intelligence information society", which is a term that has been continuously discussed recently? This means that the automation beyond the limits of human ability in the whole societies based on intelligent information technology is a universalized social future. In particular, it is a concept that minimizes human intervention and continuously pursues evolution to data (or big data) -based automation. For example, autonomous automation is constantly aiming at unmanned vehicles with artificial intelligence as a key element. However, until now, intelligent information research has focused on the intelligence itself and has made an effort to improve intelligence logic and replace human brain and intelligence. On the other hand, in order to replace the human labor force, we have continued to make efforts to replace workers with robots by analyzing the working principles of workers and developing optimized simple logic. This study proposes important strategies and directions to implement intelligent information education policy and intelligent information technology research strategy by suggesting access strategy, education method and detailed policy road map for intelligent information technology research strategy and educational service. In particular, we propose a phased approach to intelligent information education such as basic intelligence education, intelligent content education, and intelligent application education. In addition, we propose education policy plan for the improvement of intelligent information technology, intelligent education contents, and intelligent education system as an important factor for success and failure of the 4th industrial revolution, which is centered on intelligence and automation.

As the "Partial Amendment to the Vocational Competency Development Act" was passed, and the mandatory refresher training was legislated in March 2020, HRD education institutions has prepared a plan for the improved refresher training to strengthen the competency of vocational training teachers and to improve the quality of refresher training. However, as demand for refresher training is concentrated in partial occupations, it is necessary prepare a separate plan to recognize personal learning as a refresher training for a minority of teachers who are not provided with a training. Therefore, this study aims to identify areas of a minor training occupations that don't exist many participants for a refresher training and to derive ways to recognize their multiple education experiences and participations instead of attending a refresher training. To this end, literature review, analysis of current situation, consultation with stakeholders, and written interviews with experts were conducted. As a result, a minority of training occupations was defined as type 1 and type 2 and ways of the recognition of refresher training for minority of training occupations which embrace various educational types were derived. Lastly, discussions and suggestions on the expansion of the scope of the recognition of refresher training for minority of training occupations were provided.

To cultivate talented people with creative and convergent thinking skills to live in the era of the 4th industrial revolution, the national curriculum of Korea is gradually emphasizing convergence education and software education. To meet the demands of the times, this paper suggests subject-convergent teaching-learning materials for educating core principles of Support Vector Machines, especially targeting elementary learners. Based on analysis of the national curriculum, achievement standards of three subjects are integrated. After printable worksheets for traditional face-to-face classes had developed, they were transformed to online interactive worksheets for non-face-to-face classes. The teaching-learning materials are expected to promote the growth of the learners' academic motivation and knowledge.

With the popularization and application of artificial intelligence technology in daily life, new ethical and moral problems constantly appear in human society. These ethical and moral problems have been associated with people's moral behavior and have become crucial issues. In traditional social situations, researches have proved that moral intensity affects people's moral behavior. However, in the context of applying artificial intelligence technology, the mechanism between moral intensity and moral behavior is unknown. Therefore, this study focuses on the relationship between moral intensity and moral behavior in the context of applying artificial intelligence technology, and introduces a new concept - technology moral sense (TMS) into the theoretical model. Research method: We set various situations of applying artificial intelligence technology and adopt the situational experiment method to analyze the relationship between moral intensity and moral behavior in different application scenarios. The results show that moral intensity has a significant influence on moral behavior, while the technology moral sense performs a mediating function.

Ministry of Education, Culture, Sports, Science and Technology in Japan defined the needs for children who will lead the 21st is "Strength to lead a life" and the "New course of study" was developed and it have been adapted into elementary school from 2011 year. In order to respond to changing educational environment in terms of Information education, in 2010 year, "New Growth Strategy Conference" was held and "New Strategy in Information and Communications Technology" was announced, instructional system was made up through the research "The Vision for ICT in Education" in 2011 year. In particular, elementary schools is doing Computer Science Education in connection with general subjects, it means that preparation process for secondary education in terms of Computer education which is started in earnest. These Computer Education in Japan imply the further ways of Computer Education in Korea which are instructional system linked with Elementary school and Secondary school and computer education based on informatics.

In order to create and utilize experiential equipment that can be effectively used in school safety education, this paper uses the Korean Safety Education Association's CPR simulator to utilize the elements of educational games: goals, rules, competition, challenge, fantasy, safety, and fun. When the content that combines game elements with general educational equipment was utilized in school education sites, significant results were obtained on the effectiveness of education with active participation of students.
