The current study aimed to identify the effectiveness of a training program based on multimedia in developing the semantic level of language in children with developmental language disorder, and to reveal the extent to which the effect of the program remains after its cessation. The experimental method was used in the study, and the study sample consisted of (14) male and female children from Children with developmental language disorder, aged between (5-7) years, will be divided into two equal groups (7) children as an experimental group, and (7) children as a control group. The study tools were the Stanford-Binet Intelligence Scale, picture five (Arabization). / Safwat Faraj, 2011), the Developmental Language Disorder Diagnosis Scale (prepared by Abdelaziz Al-Khakhas et al., 2018), the Neurological Survey Test (Arabization and Standardization/ Abdel-Wahab Kamel, 2007), and the Semantic Level of Language Scale (prepared by Hassan Abdel Moati, Hassan Muslim, and Shaima Lutfi, 2021), and the results resulted in statistically significant differences between the average ranks of the scores of the experimental and control groups (of children with developmental language disorder) in the post-measurement of the semantic level of language (dimensions and the total score) in favor of the experimental group, and the presence of statistically significant differences between the average ranks of The scores of the experimental group (of children with developmental language disorder) in both the pre- and post-measurement of the semantic level of language (dimensions and the total score) are in favor of the post-measurement, and there are no statistically significant differences between the average ranks of the scores of the experimental group (of children with developmental language disorder) in The post and follow-up measurements of the semantic level of the language (dimensions and total score), and the results were interpreted in light of the theoretical framework and previous studies, and a number of recommendations and proposed studies were presented. Key Words: developmental language disorder - semantic level of language - multimedia.
