  　View Summary

  This study reports findings from a large-scale survey of 12,141 students and 1,216 teachers in Okinawa Prefecture on the educational use of generative AI. Student use increases with grade level, shifting from information searching to idea generation in junior high school. Although 83.4% of teachers reported using generative AI, only 23.7% understood national guidelines. A clear perception gap was identified: students tend to view AI as a learning assistant, while teachers express concerns about reduced thinking skills. The findings underscore the need to frame AI as an intellectual partner and to promote AI literacy through empirically grounded instructional design.

• Training Program Design and Evaluation Aimed at Developing Generative AI Literacy for Junior High School Teachers

  　View Summary

  In recent years, generative AI technologies have rapidly advanced, attracting significant attention in the field of education. The guidelines published by the Ministry of Education, Culture, Sports, Science and Technology (MEXT) highlight the necessity of generative AI literacy from three perspectives: “understanding the mechanisms of generative AI," “perspectives for utilizing AI in learning," and “developing the ability to effectively use AI." However, no training program currently exists that is based on these perspectives. Therefore, this study designed a training program (hereafter, the training program) for junior high school teachers based on the three perspectives mentioned above and examined its effectiveness. As a result, a survey on attitudes toward generative AI revealed that many teachers' perceptions of generative AI shifted positively after the training, suggesting the effectiveness of the program. Additionally, the study identified the need for further investigation into the long-term effects of literacy education as an ongoing challenge.

  　View Summary

  The rapid spread of generative AI has created an urgent need for teacher training in Japan, where formal professional development programs are lacking despite new guidelines from the Ministry of Education (MEXT). This study addresses this gap by designing and evaluating a generative AI literacy program for 50 in-service teachers in Okinawa. The program, structured on Gagné's Nine Events of Instruction, was assessed using pre- and post-training surveys. The initial survey revealed significant challenges, with 92% of teachers unaware of the MEXT guidelines and 74% citing a lack of knowledge. Following the training, results showed a dramatic positive shift, with significant improvements in participants' AI knowledge, ethical understanding, and confidence. Qualitative feedback also indicated high satisfaction and strong motivation for practical application. The study concludes that the program is an effective model for fostering generative AI literacy among educators, successfully transforming their initial apprehension into proactive confidence. Future improvements will focus on allocating more time for hands-on exercises to meet expressed participant needs..

• A Study on Reducing Students' Affective Filters in English Reading Comprehension through All-English Instruction : Features of English Activities Aimed at Reducing Psychological Barriers in All-English Reading Instruction

  Type of publication: Research paper (bulletin of university, research institution)

  　View Summary

  The purpose of this study is to identify psychological barriers from the students' perspective in English reading instruction that does not rely on Japanese, to present an educational psychological approach to mitigate these issues, and to clarify the characteristics of this approach. The study was conducted through basic English classes (CEFR A1-A2) at a mid-level school in Okinawa. In the target group, psychological barriers to All-English reading instruction were identified, with contributing factors including difficulties in understanding classes conducted entirely in English, increased feelings of inadequacy, and anxiety. It was also suggested that elements of “fun" and kinesthetic reading activities reduced the psychological barriers in the target group, indicating the characteristics of materials and English activities that contribute to the success of All-English reading instruction. It was found that reading activities, not limited to traditional classroom settings but also incorporating kinesthetic learning and interactive activities, helped alleviate tension towards the All-English class environment.
