The purpose of this study was to investigate the learning effectiveness of a student with cerebral palsy applying movement analysis model to aquatic activity curriculum. Specifically, it was to examine the effects on the cognition of action concept, the acceptance of the curriculum, and the adaptation of the water. The participant was a student with cerebral palsy. The aquatic activity curriculum was carried out one-on-one. This is a case study with the treatment continued for eight weeks with 40 minutes a lesson and two lessons per week, a total of 16 lessons. Both qualitative and quantitative approaches were used for data collection. The qualitative data were collected by interview, observation, work sheets, concept mapping sheets, and teaching journals. The data were analyzed by constant comparison and triangulation method. For the quantitative study, the data were collected by systematic observation during instructional time. These data were analyzed using descriptive statistics. The findings were as follows: (1) The aquatic activity curriculum applying movement analysis model helped the participant in construction of the cognition of action concept, including the components of body, effort, space, and relationships. (2) The participant showed high level of acceptance to the aquatic activity curriculum of applying movement analysis model. (3) Applying movement analysis model to aquatic activity curriculum promoted the learning effectiveness of the adaptation of the water for the student with cerebral palsy. The findings above illustrated that applying movement analysis model to aquatic activity curriculum helped to promote the development of cognition, affection, and psychomotor of the student with cerebral palsy. In conclusion, related suggestions and recommendations were proposed for instruction purpose.
