Summary: | 碩士 === 國立臺北教育大學 === 特殊教育學系碩士班 === 101 === The purpose of this study was to investigate the effects of physical movement before class on decreasing off-task behavior of student with intellectual disability in a vocational senior high in special education school. A single-subject withdrawal and reversal experiment (A-B-A-B) design was applied. Three students with intellectual disability in a vocational senior high in special education school participated in this study. The independent variable of this study was the physical movement before class, and the dependent variable was off-task behaviors. Using a partial interval recording system, each off-task behavior was recorded on an observation form developed by the researcher. Visual analysis and time series C statistics were used to conduct data analysis. Social validity of the intervention was also discussed based on the results of interviewing other teachers in the classroom.
The major findings of this study were summarized as follows:
1.The physical movement before class was successful in decreasing off-task behavior of student with intellectual disability in a vocational senior high in special education school. All the participants’ off-task behavior decreased as a result of intervention.
2.The physical movement before class intervention was successful in decreasing the following 3 target behaviors: “ looking away from teacher for at least 3 seconds,” “playing objects for at least 3 seconds,” “chatting and playing with classmates for at least 3 seconds.” Although the fourth target behavior, “taking longer than 3 seconds to respond to the teacher’s instruction,” did not decrease significantly, the number of intervals during which students performed this behavior still showed a slightly decreasing trend.
3.Other teachers in the classroom confirmed the effect of physical movement intervention. They reported that participants’ off-task behavior decreased after intervention, and the intervention effects were maintained and generalized to other classes.
Finally, some suggestions based on the findings of this study were provided for teaching and future studies.
