    Review matching task to diagnose basic review ability

    by Koki Saito - March 29, 2024

    Software development begins with writing a requirement definition document (RDD) specifying what software is to be built, and the RDD should define the necessary and sufficient conditions the software must satisfy. Preferably, the RDD is reviewed to guarantee its quality. However, the quality of reviews of such documents is not easy to evaluate, due to various review styles and the logical complexity of RDDs. Therefore, we regarded the review ability as the ability to match an RDD with a software and developed a game to make a matching task that can assess review quality. The task has four types of relationships, two-by-two classes of necessity (i.e., the RDD has no irrelevant sentences to define the given software) and sufficiency (i.e., the RDD covers all the parts of the software), between requirements and software, which are expressed in verbal and nonverbal forms. Results suggest that the game likely sufficiently simulated the process of making/reviewing RDD in the requirement definition process. Therefore, it is suggested that the matching task created through the game can be adequate to assess the review ability.

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

    by Takahiro Sato - October 24, 2023

    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.

    A case study of the use of match video analysis tools in Judo: Attempts of visualizing the competition realities of an athlete

    by Ryosuke Ozaki - November 13, 2023

    In this study, we analyzed match videos of a university Judo Player (Player A) utilizing the SPLYZA TEAMS matched video analysis tool. This is the first case study of Judo match analysis using the SPLYZA TEAMS software. A total of 13 matches involving Player A were analyzed in this study. Prior to the analysis, Player A formulated three hypotheses for the matching implementation. The analysis rejected two of the three hypotheses established at the beginning of the study. However, a notable trend emerged, revealing a proclivity for the Kumite situation for initiating Nage-waza from disadvantaged positions in matches that resulted in a loss. This novel finding was obtained by analyzing the data using the SPLYZA TEAMS software.

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

    by Goichi Hagiwara - December 6, 2023

    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.
