The purposes of this study were (a) to examine skill acquisition in field hockey of seven junior-high school students with PDD, who attended an inclusive class; and (b) to compare the degree of skill acquisition in field hockey of junior-high school students without disabilities who attend an inclusive class and those who attend a regular class. The motor performance of the students with and without PDD was compared using specially designed field hockey skill tests, before and after a skill acquisition period of two 45-min sessions. Results indicated that (a) students with PDD significantly increased motor performance in the cone circling (CC) task (p less than 0.002); and (b) the percentage gain score of students without disability in the regular class was significantly better in the CC task (p less than 0.02) compared to that in the inclusive class, but did not differ in the slalom between cones task.
