Development and clarification of the effectiveness of 20-m shuttle run measuring system for deaf students

本研究的目的是建立聋哑学生20米穿梭跑测试系统，并阐明该系统的有效性（可得性）。穿梭测试在25所聋哑学校（占日本所有聋哑学校的42%）进行，其中包括23个小学水平组，14个初中水平组和8个高中水平组。在大多数学校里，这些聋哑学校的老师们打鼓，挥舞着带有电子声音的旗帜，和学生们一起跑步。观察到学生在注意电子声音控制自己的跑步速度和随着电子声音的加速而跑步时所面临的困难。通过对数据的分析，在聋哑学生面前根据电子声音进行图片展示是最有效的。把LED灯放在地板上，与电子声音同步应该是有效的。我们的新系统与聋人学校自己的方法识别数据的差异表明了一些发现：1)初等水平组与聋校自己的方法无差异；2)初等水平组对电子声音的识别速度有差异，但对其加速的识别没有差异；3)高中水平组对电子声音的识别速度和加速有差异。结果表明，新系统可以立即适用于高中水平的学生，也可以通过重复练习适用于小学和初中水平的学生。

The purpose of this study was to develop 20-m shuttle run measuring system for deaf students and to clarify the effectiveness (availability) of the system.The shuttle run tests were conducted at 25 deaf schools (42% of all the deaf school in Japan), which included 23 elementary level groups, 14 junior high level groups and 8 high school level groups.The teachers of these deaf schools played drums, waved flags with electronic sounds and ran with their students in most schools.The difficulty that students faced in controlling their own running speed with attention to electronic sounds and running in accordance with speed-up of electronic sounds was observed.Picture presentation in accordance with electronic sounds on the floor before deaf students was the most effective by analyzing the data. To place the LED light on the floor, synchronized with electronic sounds should be effective.The recognition data difference between our new system and deaf schools' own method indicated some findings as follows: 1) no difference was observed between our new system and deaf schools' own method in elementary level groups, 2) difference on recognition of electronic sound' speed was observed, but no difference on recognition of it's speed-up was observed in junior high level groups, 3) difference on recognition of speed and speed-up of electronic sounds was observed in high school level groups.It was indicated that new system was immediately available to high school level students and also available to elementary and junior high level's students with repetitive practice.
