Teachers continually seek to find new and innovative ways to create classroom environments conducive to learning to discourage problem behaviors in students. Alternative seating, such as therapy balls and seat cushions, has been widely researched and found to have a positive relationship in decreasing student problem behavior and increasing overall focus, particularly with students identified as having a disability, such as autism or attention deficit hyperactivity disorder. A new form of alternative seating, called a hokki stool, has increased in popularity as teachers find innovative ways to design their classrooms. While there are many anecdotal claims of the effectiveness of hokki stools in curbing problem behavior in students, a gap in the literature exists as hokki stools have never been studied in any meaningful quantitative way. Built on the foundations of behavioral theory, sensory integration theory, universal design for learning theory, and transformational leadership theory, the research questions of the study were designed to measure what effect hokki stools have on student physical aggression, verbal aggression, and disruption. Participants included students and faculty of a small, public, therapeutic, alternative school designed for students with special needs and challenging behavioral problems. The research was conducted in an A-B model, wherein student behavior data were compared between using hokki stools versus traditional chairs, using student's t-test for analysis. Although the findings of the study show physical aggression, disruption and elopement decreased in frequency; the decrease was not statistically significant enough to be attributed to the presence of the hokki stools. Limitations of the study and recommendations for future research are provided. [The dissertation citations contained here are published with the permission of ProQuest LLC.
