Visual analysis of single-case experimental design data for graduate students of special education

This article presents the details and findings of implementing a training program to support graduate-level university students of teacher education in the practice of visually analyzing data presented in graph form obtained through A-B single-case experimental design. The training was presented as part of a graduate-level course offered at a university in Riyadh, Saudi Arabia. All 28 students enrolled in the three sections of the course were invited to attend the 2-h visual analysis training and consent to participate in the research, although attendance and participation were not required. Of these 28, 21 attended the training on the designated dates. Pre- and post-tests were employed to assess the effectiveness of the program and A-B graphs adapted from Lane et al. (2021) were developed for the study. Post-test scores indicated marked improvement regarding the correct use of the six aspects of visual analysis. Improvement in overall visual analysis accuracy was also found. Implications, recommendations for future research, and limitations are provided.
