Hearing-impaired students struggle with writing, frequently make errors, and have limited sentence construction skills. Current learning platforms like Google Classroom do not have sign language support or content specifically designed for students with lower written comprehension, leading to frustration, sentence structure difficulties, and decreased motivation, as their unmet needs affect academic achievement. This study aimed to investigate if Let's Write, a mobile application, could address the essential writing skills needed for simple sentences, specifically focusing on the Preposition of Positions. The goal was to improve handwriting, accuracy, sentence structure, and punctuation by comparing it to the Google Classroom learning platform. The study was conducted using an experimental design, and the participants were chosen from government schools in Perak and Penang using purposive sampling. The study divided 80 hearing-impaired students into control (n=40) and experimental (n=40) groups, each using a different platform. Pre-tests, treatment (platform use), and post-tests were used to measure academic progress, while questionnaires assessed usability and motivation. The results showed that the Let's Write application provided a significantly more user-friendly and interactive learning environment. Students using the Let's Write application displayed higher self-assessment, focused on learning from mistakes, sought independent knowledge, and reported overall satisfaction. Importantly, the Let's Write application group showed greater academic improvement than the Google Classroom learning platform group. This suggests that mobile applications, particularly those incorporating sign language, can greatly enhance learning for hearing-impaired students by improving usability and learning motivation. It highlights the importance of tailored educational technologies in bridging the achievement gap. The study provides valuable insights for educators and developers to refine digital learning tools further.
