The usability of such systems is important for students' learning. Objectives: This study aimed to evaluate the usability of the NAVID electronic learning (e-learning) system using the cognitive walkthrough method. Methods: In this cross-sectional study, validated and reliable checklists, confirmed by an expert panel, were used to measure three key dimensions of usability: Effectiveness, efficiency, and satisfaction from the point of view of 30 medical informatics graduate students, 29 professors from the basic and clinical science departments of the faculty of medicine, and 2 system experts from Tabriz University of Medical Sciences in the first semester of the 2022 - 2023 academic year. The effectiveness of tasks was calculated using the completion rate formula. Efficiency was calculated using a time-based efficiency formula. Satisfaction was measured using a seven-point Likert scale, with scores above 5.5 considered good and below 5.5 considered poor. Results: From the professors' perspective, the task completion rate was 87.5%. The overall efficiency for this group was 85%, with a satisfaction level of 75.2%. Among students, the task completion rate was 83.3%, with an efficiency of 85% and a satisfaction score of 81.1%. Experts reported a 100% task completion rate and efficiency, with an overall satisfaction level of 81.3%. Suggestions for improvement included enhancing interaction options, improving system performance during exams, full-time system support, and addressing technical issues like microphone quality. A positive correlation was observed between effectiveness and satisfaction, as well as between effectiveness and efficiency, for both students and professors. However, there was no significant correlation between efficiency and satisfaction in these groups. In contrast, all three dimensions were correlated in the experts' group. Conclusions: While the system demonstrated overall acceptable usability, particularly in task completion rates, the findings reveal critical areas that require significant enhancement. The challenges faced by users, particularly in accessing essential system functions such as password recovery and course management, indicate a need for a more user-friendly design. Additionally, correlations among the various usability dimensions were noted, indicating that enhancements in one area are likely to result in overall improvements in system usability. pubtype: Academic Journal doctype: equations & formulas research tables/charts Journal Article ougenre: Article language: English refInfo: holdings: @attributes: islocal: N |
