Phonological Awareness (PA) in deep orthographies like English can be used to predict reading abilities in later grades. PA is a sensitive measure in identifying Arabic speaking children who struggle to read. The main objective of the present study was to compare two matched versions of a sound blending task to determine whether any of the two created versions (i.e., one with short vowels and the other without short vowels) of this task could yield a more accurate measure of PA in children speaking Jordanian Arabic. Data was collected from 20 randomly selected schools in Jordan. A randomly selected sample of 200 participants in grade 4 who were randomly divided into two groups (100 students each) and were tested on word blending, elision, word recognition, and oral reading fluency. Each group of participants was tested using a different version of the word blending task, while the other tasks used to test the two groups were the same. The major finding of the study revealed a significant difference between the two versions of the blending task in favor of the assumption that using a task without short vowels can produce inflated scores (i.e., the blending task without short vowels yielded higher scores); such scores demonstrated weak correlation with the reading measures. The implications of the current study support the presentation of blending tasks with all the constituent segments of the word including short vowels (i.e., presenting the word with consonants, long vowels, and short vowels), which can better contribute to gauging children's PA abilities.
