Designing and Studying the Effectiveness of Nava Game Multimedia Software in Teaching the Diagnosis of Dysarthria Symptoms in Speech Therapy Students

Background: Previous studies have found educational games effective in improving students’ learning quality and enhancing their ability to apply material in clinical environments. Therefore, this study designed the Nava Game Multimedia Software to teach dysarthria diagnostic skills to speech therapy students and examined its effectiveness in this population.Methods: This non-experimental descriptive-analytical study evaluated 42 speech therapy students who were divided into two groups. After designing and producing the content for the Nava educational game, the first group learned about dysarthria through theoretical instruction. In contrast, the second group received theoretical instruction supplemented by the Nava software. At the end of the training, students’ knowledge was assessed through final exam scores, and their attitudes were measured using a researcher-developed questionnaire.Results: The mean ± standard deviation scores for the first group were 15.01 ± 1.32, and for the second group were 17.86 ± 1.04. The difference between the two groups was significant (p < 0.001). Attitude scores also differed significantly between the first group (29.61 ± 14.72) and the second group (43.14 ± 16.50) (p < 0.001).Conclusion: Nava is a game-based software that can be installed on an Android phone. Its use led to increased learning, improved students’ attitudes toward learning, and greater satisfaction among both instructors and students regarding dysarthria diagnosis.
