The effectiveness of montessori method education on visual-motor abilities of students with nonverbal learning disorders

The purpose of the present study was to investigate the effectiveness of Montessori method education on the visual-motor abilities of students with nonverbal learning disorders. For the purpose of this study, 4 first grade male students with nonverbal learning disabilities who were studying at Nabi Akram primary school in Bonab, during the academic year of 2019-2020, were selected based on the bender visual - motor gestalt test. In this research, which is a single-subject design with multi-baselines (ABA), each participant was first carefully observed according to the criteria of nonverbal learning disability and their visual-motor cognitive abilities accurately measured and recorded. Then, during the intervention phase, each participant received the Montessori method education during the 10 sessions for 45 minutes separately. The performance of the participants is also observed in the follow-up sessions. Finally, the data was analyzed by analyzing the visual diagrams, percentage of all non-overlapping data (PAND), calculating the effect size index and recovery percentage. The results of the research showed that the Montessori method education increased the visual-motor abilities of all four participants. As a result, Montessori education can be used as part of empowerment programs for students with nonverbal learning disabilities.
