Instructional Package of Development of Skill in Using Fine Motor of Children for Children with Intellectual Disabilities

This research has the following purposes: 1) to find the efficiency of the selflearning activity set on development of skill in using fine motor of children with intellectual disabilities., 2) to compare the abilities to use the small muscles after the study more than before the study of children with intellectual disabilities, who made study with the self-learning activity on development of small muscles use., 3) to study the satisfaction of the children with intellectual disabilities using the self-learning activity on development of small muscles use. The sample groups on the research are the children with intellectual disabilities of the special education Maha Chakri Sirindhorn Provincial Nakhon Nayok Center in the school year 2016, for 7 children. The tools used on the research consist of the self-learning activity on development of small muscles use for the children with intellectual disabilities of the special, the observation form of abilities of small muscles before and after using the activity set and the observation form of satisfaction of the children with intellectual disabilities of the special towards the self-learning activity set on development of small muscles for the children with intellectual disabilities of the special. The statistics used on the research include the percentage, mean value, standard deviation and the t-test for dependent sample. From the research, it was found that the self-learning activity set on development of small muscles use for children with intellectual disabilities of the special is efficient based on the criteria in average equal to 77.78/76.51, the educational coefficient of the student after the study higher than before the study with average points before the study equal to 55.14 and S.D. value equal to 3.72. The average points after the study equal to 68.86, S.D. value equal to 2.73, t-test value before and after the study equal to 7.94, which are different significantly on statistics at the level 0.05 and the satisfaction observation form of the student towards the self-learning activity on small muscles use for he down syndrome children with average value equal to 4.58 in the
