Abstract : This study evaluates the web-based Animated Tutor PECS (AT-PECS) using the Picture Exchange Communication System (PECS) method as a means to increase the ability to initiate communication independently in children with Autism Spectrum Disorder (ASD). The objects of this study were children under 5 years of age who had ASD with limited communication skills before being treated using the AT-PECS application. Methods:This study designed an alternating treatment to examine the use of AT-PECS as the primary technique for improving students’ abilities with PECS and increasing students’ independent communication initiatives. Results: The results obtained from this study indicate that students can accept the use of the PECS method for learning and show an increase in communication initiative skills independently, but the speed in improving vocabulary looks faster when using the AT-PECS application. Conclussion: The study indicate that using the PECS intervention method with the help of ATA can improve the communication skills of ASD children and improve verbal abilities to a certain extent.
