Factors Affecting the Writing Performance in Hearing and Deaf Children: An Insight into Regularities and Irregularities of the Arabic Orthographic System

This study aims to account for the underlying causes of spelling errors in hearing and deaf children who speak a dialectal form of Arabic that substantially differs from the standard written one. It presents a general overview of the spoken Arabic language and its written system, drawing attention to some of the phonological and orthographic regularities and irregularities used in constructing and decoding Arabic words and sentences. It also accounts for the diglossic factors that interfere with the process of phoneme-to-grapheme mapping. The spelling outcomes of a group of hearing children are compared with another group of orally educated deaf children, who in addition to the complexity and diglossity of Arabic, have limited hearing abilities. Both groups performed two written tasks, one representing the standard form and the other representing the dialect. These tasks identified the types of spelling and segmentation errors and the effects of the committed errors on children's awareness of the concept of word and word boundaries. Analysis of the results reveals their spelling errors' nature and frequencies, and progressively categorizes the most prominent errors in practicing each language form. The deaf group (n = 30) produced significantly more errors than the hearing group (n = 36) in the dysphonetic errors and the word omission categories. The findings indicate that the sociolinguistic context of the Arabic language and the orthographic nature of the Arabic script are both important factors affecting hearing and deaf children's awareness of the concept of word as well as their spelling performance. These results may enable educators to understand the underlying factors of Arabic spelling and produce targeted error correction strategies to maximize children's learning outcomes.
