students made mistakes in composing a correct sentence structure. Meanwhile, lecturers require these students to master the correct sentence structure. Therefore, this study aims to determine the effect of I-CHAT as a learning medium on the students’ ability to write correct sentence structures. This study used a quasi-experimental design research with one group pretest-posttest research design. The subjects of this study were five deaf students of University of Lambung Mangkurat. The data was collected using a test to compile sentence structures related to the course of Child Education with Intellectual Obstacles, observation, and documentation. The data were analyzed using Wilcoxon Ranking Test (Wilcoxon Signed Rank Test). The results of this study showed that the deaf students’ ability to structure sentences improves from mean score 34 to 54 after learning using I-CHAT media. Statistical calculation using Wilcoxon Signed Rank Test proved that there were differences between mean scores of pre-test and post-test of the sample after implementing I-CHAT media. It can be concluded that the use of I-CHAT media improves the ability of the deaf students to structure sentences.
