Development of an Interactive Learning Assistive System for Students with Intellectual Disabilities Using Robot with Audiovisual Intervention

Intellectual disability is a condition in which an individual has a below-average intellectual level, resulting in difficulties in the learning process. To fulfill the right to education, the government has developed a policy through the implementation of special school. However, despite the existence of SLB, the learning process of students with intellectual disabilities often does not run smoothly because they have difficulty focusing on long-term instructions and are easily distracted by visual distractions. Therefore, assistive technology is needed that is able to attract students' attention during the learning process. Previous research has developed a robot-based interactive learning system for people with intellectual disabilities that is able to improve students' understanding of the material. However, the robot system does not yet have a two-way interaction feature between the robot and students. This research aims to develop the interactive learning system by adding two-way interaction features. The development is done by improving learning materials in the form of verb spelling and student interaction through answer cards. During the learning process with the robot, students showed interest in the robot's motion capabilities and the audiovisual material displayed. Subjects paid close attention to the robot, which led to a significant increase in the average correctness rate of typesetting from 25.55% during conventional learning to 63.86% with the robot. The standard deviation of robot learning was 26.54, while conventional was 18.47, indicating higher consistency with the robot. Factors such as subjects' memory performance and learning environment conditions may affect the inconsistency of the results. Robotic learning proved to be effective for subjects A and C, and moderately effective for subject B. Future research development plans include real-time data collection and processing with IoT as well as increasing the level of materials such as counting and social skills of money use.
