Abstract Stability balls are promoted as an effective alternative to chairs at a classwide level, yet there are no published studies documenting classwide outcomes. Therefore, the purpose of this study was to investigate classwide effects of stability balls and attempt to provide empirical support for their use. Using an A-B-A-B reversal design, this study examined the effectiveness of stability balls in comparison to classroom chairs in a second-grade classroom. Student on-task and out-of-seat behaviors were measured using direct observation. Academic productivity was measured using curriculum-based measures of written expression. Similar patterns of responding for on-task and out-of-seat behavior were found while students were seated on traditional chairs and stability balls. Results demonstrated similar rates of improvement in writing fluency over the course of the study. Overall, teacher and student social validity measures indicated high levels of acceptability of stability balls in the classroom.

调查稳定球对全班级学生行为和学术生产力的影响

摘要提倡在全班级使用稳定球代替椅子，但是尚无公开的研究记录全班学习的成果。因此，本研究的目的是研究稳定性球的全班效果，并为使用它们提供经验支持。使用ABAB反转设计，本研究检查了稳定球与二年级教室中的课桌椅相比的有效性。使用直接观察来测量学生的上班和就座行为。使用基于课程的书面表达量度来衡量学术生产力。当学生坐在传统椅子和稳定球上时，发现了类似的应对任务和座位外行为的模式。结果表明，在整个学习过程中，书写流畅度的提高速度相似。总体而言，师生的社会有效性测评表明教室里稳定球的接受度很高。
