Abstract

This study developed and evaluated KAAYA, a low-tech wearable augmentative and alternative communication device to improve functional and expressive communication in a child with mild intellectual disability. A mixed methods design integrated quantitative and qualitative data. One eight-year-old participant with adequate receptive language but limited expressive skills received the intervention. Data sources included structured classroom observations, a receptive and expressive communication rubric, pretest and posttest assessments, and interviews with teachers and parents. The pretest total score was nine, indicating reliance on nonverbal gestures and difficulty expressing basic needs. After three weeks, the posttest rose to twenty-four,24, and the child used KAAYA buttons to request food, toileting, and play. Session-by-session observations and PND indicated progressive gains during intervention. Qualitative data showed reduced miscommunication, greater independence, and improved social participation at school and home. Results suggest that KAAYA is an effective, practical, and context-appropriate low-tech wearable AAC device for supporting functional communication and social participation in children with mild intellectual disabilities across structured educational settings and daily routines.

Abstract

This study aims to measure the effectiveness of the Biological Augmented Reality (BAR) learning media in improving understanding of the "Human Immune System" Material among deaf junior high school students. The Research employed an experimental method with a one-group pre-test-post-test design, involving six deaf students from SLB X. Participant criteria included diagnosed hearing impairments, junior high school age, basic literacy skills, and the absence of severe cognitive impairments. The procedure began with a pre-test consisting of multiple-choice questions to assess prior knowledge. Subsequently, students participated in learning sessions using BAR media, designed to present three-dimensional visualizations and interactive features to facilitate understanding of abstract concepts. A post-test was then administered to evaluate changes in students' comprehension. Data from the pre-test and post-test were analyzed using the nonparametric Wilcoxon test to identify significant differences. The results revealed a significant improvement in students' understanding after using the BAR media. The media's visualization and interactivity not only enhanced learning engagement but also helped students process information more effectively. This study recommends BAR media as an innovative learning alternative, particularly for deaf students, to address verbal communication barriers and support education.
