Comparison of Computerized and Manual Assessment of Dyslexia Children Test using Text Processing

Dyslexia is a specific learning disorder that can have a negative influence, especially on children’s learning success. Early detection and continuous therapy can help children achieve better success in school. Children with Dyslexia need several evaluations and therapy during the rehabilitation programs from therapists and psychologists. The Assessment was carried out manually and recorded using paper documents until recently. Besides, the children must meet the therapist physically. A computerized method for assessing Dyslexia children by using text processing is a new approach to better record the rehabilitation progress and provide a home evaluation application so that some social distancing can also be done, especially in the era of the Pandemic. In this study, the data was taken from 24 Dyslexia children during their three-month therapy program. The assessment program is done after the children follow the rehabilitation program from the therapist. During those three months, there were two times scheduled for rehabilitation and two times for Assessment. The Assessment uses three criteria, namely Writing Letter Series (WLS), Arranging Sentences (AS), and Copying Sentences (CS), that each Dyslexia child must do. Computer application for testing is developed with a scoring system implemented using text processing technique. Hamming distance and Text similarity system were applied to score the test result and then be compared with the manual scoring method performed by the therapists. In this study, The Hamming distance was done for the criteria of the WLS, reaching an accuracy of S3% compared to manual Assessment. For the criteria of AS, the Text Similarity technique achieves 96% accuracy compared to the manual Assessment, and in CS reaches 88Xs%. The results showed the high potential of applying text processing techniques in assessing Dyslexia children.
