An Inquiry-Based Learning Support System for Children in Sports Acquisition Processes

This study examined an inquiry-based learning support system for children in sports acquisition processes and describes the characteristics of a case study on the long-term collaborative process of children’s forward and backward cycle practices on horizontal bars. We analyzed 18 horizontal-bar practices for two elementary schoolchildren who had not succeeded in their backward cycle for approximately half a year. They were required to make practice plans collaboratively to succeed in their forward and backward cycles. To support their practices, we provided them with “HDMi (HDMi is the name of a system we developed in the past.),” which was developed to support reflecting on one’s physical movements using movies. The movies were also used for discourse analysis to determine where the children focused, and OpenPose software was used for motion analysis to examine how the children’s actions improved on a horizontal bar. Both the HDMi and the discourse analysis suggested that two children selected their focusing points for their practice and they gradually became referring to “move toes toward opposite side of the bar” in the periods of practices. However, the motion analysis revealed that the focused points and actual movement of the body did not match completely.

Clarifying the Sharpened network diversity in French flair rugby

This study aimed that open rugby, known as flair rugby, drives the modern game by analyzing the 2022-2023 international test matches of France representative team. We examined the superiority of a spatial tactic called French flair rugby. First, the advantage of creating a relatively large number of networks was demonstrated. From the transitivity analysis of the network (CUG test; Conditional Uniform Graph test), the cooperation occurs at a higher level than in other networks. The network graph structure showed which players functioned centrally at which time of match as unusual positions, i.e., multi-position and multi-skill. In this study, we operationally defined this diversity as the sum of the standardized eigenvector centralities. We found that the increase in the time-series score balance tended to reduce and sharpened the diversity. As a result of examining a scale-free model in network theory, Sharpening the diversity (central and transitive role players) tended of the network power law scaling.

Japanese elementary teachers’ problem-based learning through online professional development on teaching Japanese language learners in physical education  

Public schools in Japan have become increasingly linguistically, ethnically, culturally, and religiously diverse (Furuta et al., 2022). In rural regions, the number of Japanese-national students is declining in schools, and education services are shrinking (Mantanle, 2014) because of the aging population and low birth rate. This has led to serious economic concerns such as a smaller workforce and fewer taxpayers. This means that school districts in Japan will need new immigrant residents who can contribute to the sustainable future of education in Japan. However, in order to adequately serve this new population, Japanese teachers will need to receive training and demonstrate pedagogical knowledge and skills in relation to social justice and diversity, and facilitate inclusive and effective learning opportunities for all students. Our research team conducted two exploratory studies focusing on (a) Japanese elementary school teachers’ positioning in teaching physical education to Japanese language learners (Furuta et al., 2022) and (b) Japanese elementary classroom teachers’ experiences with the involvement of immigrant parents regarding physical education (Tomura et al., 2024a). Based on the findings of these studies, our research team developed online professional development modules for teachers using a problem-solving approach as part of a project funded by the Japan Society for the Promotion of Science.

The Effects of Positive and Negative Ions on esports Performance and Arousal Levels Part 2 -Testing Higher Ion Density-

The purpose of this study was to investigate the psychological effects of higher positive and negative ion conditions on the arousal levels of esports players during a racing game. Participants (10 males) from a collegiate esports team were the participants in the study. The effects of higher concentrations of positive and negative ions were evaluated in a randomized crossover. Each participant performed two experiments four weeks apart; two experimental environments were used: positive and negative ions filling the atmosphere (PNI) condition and a control (CON) condition. A car racing game was employed as the performance task. Arousal was measured by the two-dimensional mood scale (TDMS) and electroencephalogram (EEG). EEG was used to measure arousal. The results showed that the level of arousal in the subjective assessment and the level of arousal in the EEG were significantly higher in the CON condition for PNI. In addition, PNI performed significantly better on the game task than in the CON condition. The present study demonstrated in positive and negative ion environments with higher concentrations than in the previous study, and the results showed higher arousal levels in subjective assessments, indicating that higher concentrations of ionic environments are beneficial for esports players.

Practical research on the use of digital pens in high school rugby club activities

Tactics play a crucial role in sports; however, coaching presents various challenges. This study examined the impact of utilizing practice notes created with a digital pen capable of simultaneously recording and playing back both audio and texts/drawings on tactical understanding. The participants were high school rugby team members and coaches. The results of a four-month practical investigation revealed that the learning experiences of tactical understanding in high school rugby teams manifested through four categories: awareness of the difficulty of tactical understanding, exploration of experiential facts, contemplation, and integration into practice. It is speculated that the utilization of the digital pen not only encouraged a deeper understanding of tactics through the formation of a meta-perspective but also led to learning strategies aimed at activating knowledge.

Visualization of Motion Image by Humanoid Input Device for Shooting Motion in Basketball and Its Effectiveness

The use of imagery is effective for the acquisition of sports movements. However, the details of recalled images have not yet been clarified. Therefore, the purpose of this study was to visualize the image of a basketball shooting motion using a humanoid input device. We also aimed to clarify the effects of such visualizations on the formation of the players’ movement images and the understanding of their movement skills. Six elite female athletes belonging to a professional team and six high-school female athletes who had participated in national tournaments were selected as participants, and motion images were created using a humanoid input device. The results of the analysis indicated that the detailed reproducibility of the motion images and the relationship between the individual movements and the whole movement differed according to the proficiency level of the shooting movement. In addition, it was suggested that in the acquisition of the shooting motion, the promotion of metacognitive activities for one's own motion enhances the analytical and individual sensory understanding of the motion, as well as the formation of an image that relates the whole motion.
