Development of the Physical Activity Learning through QR Code Android-Based and Teaching Books for the Deaf

Science and technology in the Industrial Revolution 4.0 era had a great influence on the preparation and implementation of technology-based physical activity learning strategies. Difficulties in conveying information and learning physical activity are still often found in the learning environment for children with special needs. This research aims to make a product and validate Physical Activity learning media using digital technology based on the Design and Build Technology of the Android Book Quick response (QR) Code Application. The way is adapted to the Physical Activity guide with a bar code system to explain the sequence of Physical Activity movements in improving the motor skills of deaf students through videos that will appear after scanning the QR code. The method used in this study is research & development. The data analysis technique used Microsoft Excel. The results of this study obtained optimal content validity values (Aiken V = 0.89). The internal validity values were average (r = 0.86). The next score was the reliability value using Cronbach's Alpha, which was 0.73. Learning instruments are valid and reliable. Therefore, the Physical Activity learning instrument using digital technology based on the QR Code Android Book Application Design Technology can be used as a medium of learning and training for students with special needs.
