Validity and Reliability of Sign Language Vr Media for Deaf Children’s Motor Skills

Abstract

This study aims to validate the gesture coordination learning media based on virtual reality (Vr) technology in sign language in improving the motor skills of deaf children. The method of this research is quantitative descriptive. The data collection technique was through the FGD focus group discussion by asking for opinions from 9 experts consisting of: 3 experts in the field of learning media, 3 experts in the field of children with disabilities, and 3 experts in the field of design and ergonomics, as well as 3 experts from extraordinary school teacher practitioners. The research instrument used a questionnaire given to experts to validate the sign language virtual reality (vr) technology-based motion coordination learning media that had been designed. Data analysis uses narrative to develop a design for motion coordination learning tools based on Virtual Reality (Rv) technology, and Aiken’s V analysis to test the validity of motion coordination learning media instruments based on Virtual Reality (Rv) technology, and the cronbach alpha test to test the reliability of the instrument. The results of the study show that in the content aspect of the result of the Aiken’s V coefficient of 0.888, the design aspect shows the coefficient value of Aiken’s V of 0.902, and the aspect of use shows the coefficient value of Aiken’s V of 0.891. Furthermore, an average reliability score of 0.831 was obtained. This means that it can be concluded that all aspects of the gesture coordination learning media based on virtual reality (VR) technology in sign language to improve the motor skills of deaf children have high validity and reliability of the content of the instrument.
