Pre-screening children for specific learning disabilities (SLDs), e.g., dyslexia, is essential for effective intervention. With a quick and reliable pre- screening result, special education coordinators (SEN- COs) can provide students with early intervention and relieve their learning pressure. Unfortunately, due to the limited resources, many students in Hong Kong receive dyslexia assessments beyond the golden period, i.e., under the age of six. To this end, information technology could establish automatic pre-screening tools to address this issue. However, dyslexia pre-screening for children learning Chinese is challenging due to the lack of sound-script correlation in Chinese. In this paper, an Automatic Dyslexia Pre-screening System (ADPS) is developed to provide a quick test to identify at-risk children. Through a two-stage approach, we first develop a gamified tool based on linguistic characteristics and then evaluate the result by a comparison study. Results from a pilot test on 30 students with dyslexia and 32 students without dyslexia indicate that ADPS can effectively distinguish two groups of students. Furthermore, the interactive design elements can motivate students to conduct the pre-screening independently. Copyright © 2024 IEEE.

Dyslexia is a specific learning difficulty that affects primary school students, which is difficult to tackle through traditional school learning due to limited resources. To this end, large-scale digital learning presents new opportunities to address the need for inclusive education. A unique challenge for students with dyslexia in Hong Kong is learning Chinese characters. In this article, we investigate whether students with dyslexia can learn the writing of Chinese characters independently in an informal learning environment. For that purpose, we developed a mobile application for learning to write Chinese characters with three different writing conditions. First, students learn new Chinese characters in Condition 1: Grid+Contour+Instruction . Then, students strengthen their memory of the learned Chinese characters in Condition 2: Grid+Contour . Finally, students retrieve the memory of the learned Chinese characters in Condition 3: Grid Only . Students with dyslexia demonstrated a significant improvement after practicing with the three-condition design. For example, they wrote much slower than students without dyslexia before the study but caught up over time. This study contributes an approach to facilitate the self-paced learning of students with dyslexia at scale. © 2023 The Institute of Electrical and Electronics Engineers, Inc.
