Development of Vibration Sensor Media for Children with Special Needs at The Faculty of Sports Science, Medan State University

The purpose of this research is to describe the vibration sensor media as a learning medium for sprint competitions for blind children and to assist teachers and students in learning using vibration sensor media. This research was conducted in several steps, namely: identifying potentials and problems, gathering information, product design, product manufacturing, expert validation, product revision, testing, final production. This vibration sensor media as a learning medium for sprint competitions was first validated by material experts and media experts. Product trials were carried out on blind children in DPD Pertuni Medan with a population of 6 respondents. The small group test was 2 respondents, while the large group test was 6 respondents. This type of data collection used a questionnaire instrument. The results showed that the vibration sensor that has been made for learning sprint competitions was feasible. These results were obtained from the validation results of a) material experts at 92.5% or very feasible; b) media expert of 86.66% or Very feasible; c) small group trial of 92.5% or very feasible; d) large group trial with a result of 95% or very feasible. The vibration sensor media has been declared fit to use as a learning media for vibration sensor media.
