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

本研究旨在开发聋生20米往返跑测试系统，并验证其有效性穿梭跑测试在25所聋人学校进行（占日本聋人学校总数的42%），其中小学组23个，初中组14个，高中组8个。在大多数学校中，聋生挥舞着带有电子声音的旗帜和学生一起跑步，观察学生在注意电子声音的情况下控制自己的跑步速度和按照电子声音加速跑步时所面临的困难，通过分析数据发现，在聋生面前的地板上按照电子声音的图片呈现是最有效的。将LED灯放置在地板上，与电子声音同步应该是有效的。我们的新系统和聋人学校自己的方法之间的识别数据差异表明了以下一些发现：1）在初级组中，我们的新系统与聋校自己的方法没有差异; 2）在电子声速的识别上，我们观察到了差异，而初中组对加速的再认无显著差异，（3）速度与速度识别的差异-在高中组中观察到电子声音的上升，表明新系统立即可用于高中水平的学生，也可用于小学和初中水平的学生通过反复的练习。

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.
