Purpose：The purpose of this study was to develop an observational evaluation method for evaluating the process of rope jumping pattern development which can be adapted for use by elementary school teachers.
Method：The subjects in this study were 537 children (261 boys and 276 girls) from the first grade to the fourth grade. The rope jumping motions were recorded with a camcorder and evaluated by the method using five typical stages of motor pattern development in rope jumping. Evaluation results obtained from eight observers were compared to test the inter-class reliability of the method.
Results：The higher grade students were evaluated higher in both the rope jumping pattern and motor pattern scores. And the motor pattern score was higher among the girls than the boys. Furthermore, the range of the Cohen's coefficient of agreement in the scores was 0.76-0.95, and the ICC (3,1) of the score was 0.943. These results showed that the observational evaluation method had validity and reliability.
Conclusion：This study shows that rope jumping pattern in elementary school students develops with the student's grade. Also, the evaluation method of rope jumping pattern observation was found to be useful for teachers, and was appropriate for understanding the development of the pattern of elementary school students.
