Making students with disabilities return to the mainstream of education have been gaining attention. The population of students with intellectual disability has been higher than that of students with other disabilities. In addition to intellectual disability and adaptive problems, most students with intellectual disability have insufficient physical activity and demonstrated poor motor skills. Students with intellectual disability can benefit in their body function from structured sports activities. In-line skating is not only interesting, but also makes people's heart and lung function improved. By sharing the actual teaching experience through in-line skating can offer more information for sports workers as a reference in sports or leisure curriculum design. Moreover, it is hoped that motor skills of students with intellectual disability can be increased, and more instructive investment in roller-skating courses can be promoted.
