裁判員制度の本格導入に伴い，法教育教材の充実の必要性が増している．本研究では，中学校・高等学校の生徒に裁判員裁判における評議を簡便に体験してもらうための授業教材として，荒川（2009）の裁判員裁判ゲームをもとに，裁判員裁判ゲーム中高生版を開発した．またその有効性を検討するために， 2つの高校でシミュレーションを行った．その結果，ゲームを体験することで裁判員裁判に対する考え方が変わり，参加意欲が向上することが明らかとなった．これらの点から，法教育教材としての裁判員裁判ゲームの有効性が明らかになったといえる．

　Heart rate (HR) monitoring, which reflects exercise intensity and environmental factors, is often used for pacing strategies in the marathon race. However, it is difficult to obtain appropriate feedback for only the HR value since cardiovascular drift (CV drift) occurs during prolonged exercise. Recently, cardiac cost (CC: HR divided by running velocity) has been shown to be a potential index for evaluation of CV drift during the marathon race. The aim of this study was to clarify the relationship between CV drift and performance in the marathon race. Fourteen male university student runners participated. They carried out incremental tests on a treadmill and took part in an actual marathon race. CV drift was evaluated from differences between CC in the 0-5-km section and over every 5-km section (ΔCC). The marathon performance was examined from two viewpoints: absolute performance (average running velocity during the race: V_mar), and relative performance (V_mar against velocity corresponding to ventilatory threshold: vVT achv.). Significant correlations were found between ΔCC and vVT achv. in the 25-30 km, 30-35 km and 35-40 km sections (r = −0.672, −0.671 and −0.661, respectively), suggesting that excessive CV drift had a negative impact on relative performance. We can therefore conclude that suppression of CV drift after 25 km is an important factor for improvement of relative performance.
