     The development of AI has been remarkable in recent years, and it is expected that AI will be used in various situations. On the other hand, there is also the harmful effect of believing in the results of AI, so it is necessary to reconsider statistical education, which is science education that handles data. In this paper, we focused on learning the three elements of statistical education (Statistical Literacy, Statistical Reasoning, Statistical Thinking) from the contents of school education as what is required for statistical education in the AI era. In addition to touching on the positioning of the three elements, I introduced that many contests that are expected to utilize the learning of the three elements are being held at related academic societies.

     The social demand for data science education in higher education is only getting stronger. In response to this trend, the Ministry of Education, Culture, Sports, Science and Technology(MEXT)has been focusing on promoting mathematics, data science, and AI education. MEXT has established a certification system for educational programs and been building a consortium to promote them. This paper provides an overview of the social background, including the recent AI strategies, and provides an overview of the educational content of data science and AI required in higher education through an explanation of the certification system started in 2021 and the standard curriculum developed by the consortium. As an example, we discuss the Doshisha Approved Program for Data science and AI Smart Higher Education(DDASH).

     This study aims to clarify factors that enable homeroom teachers to use one terminal per student for collaborative learning and the relationships among those factors. In order to do so,the author provided general training to the classroom teachers as well as individual support to improve their classes. Using a modified grounded theory approach (M-GTA),the author analyzed the interviews with the homeroom teachers and teachers who were able to use one-by-one terminals for cooperative learning through training without the author's involvement. We confirmed that the growth can be explained by seven facilitating factors and three inhibiting factors. Based on the results of previous studies,we created a diagram of factors that contribute to the growth of students' ability to use one terminal per student for collaborative learning and the relationships among the factors. Among the facilitating factors,it was suggested that the experience of using the device by oneself and any previous experience of using it are important.

     Although an increasing number of students experience difficulty in typing every year,the timing and factors of their difficulties have not been identified. Accordingly,this study aimed to identify factors related to typing difficulties. A questionnaire was administered to university students and analyzed. The results revealed that students tend to experience difficulty related to the timing of high school and when to move to the following stage of education. Text mining was used to analyze the reasons,and the following five factors emerged: difficulties with keyboard input,awareness of slow input,lack of opportunities to work on a personal computer,inability to type well in class or tests,and not typing as well as others.

     The purpose of this study was to understand the actual state of elementary school students' knowledge of cloud computing through comparison with university students. Using related materials, we created perspectives for evaluating cloud knowledge, and conducted a survey based on these perspectives. As a result, elementary school and university students can understand some contents sensibly by using the cloud. On the other hand, there were contents that could not be understood only by using the cloud. Therefore, it was suggested that there is a need for teaching opportunities in elementary school.

     In this study, we aimed to construct a support system for peer review writing classes for second language learning(especially Japanese language learning). We focused on two issues of peer review writing classes:(1)learners cannot correct their essay after review because of insufficient comments by peer, and(2)it is not considered in review-process that peers review their own comments. We developed the system that extends two functions: automatic commenting and self-reviewing for comments. Through the use of the proposed system, we confirmed the following points. The first extension helped the learners to notice their mistakes. The second extension was accepted favorably by learners. Finally, we confirmed that learners want to use the developed system in the future.

     Establishment of a Wi-Fi environment in PC rooms and at other sites in schools is necessary for education of students so that they can adapt to an information-oriented society. In this environment,devices need to be prepared to enable many terminals to be used simultaneously in lectures,in addition to establishing wide service areas. There is also a need for effective management of these devices. In this report,we propose a model for development of Wi-Fi environments in schools,including design requirements,selection of devices,operation management,and changes in use by teachers and students,using a private high school as an example.
