Massive Open Online Courses (MOOCs) represent an educational innovation that promotes lifelong learning, especially for 21st-century learners. By utilizing computer technology and the internet, MOOCs offer flexible, accessible learning opportunities to a broad audience, regardless of location or background. This quasi-experimental, one-group pretest-posttest study aimed to investigate the effects of using a MOOC on Geriatric Care via the Thai MOOCs platform among nursing students who had completed the Geriatric Care course in the academic year 2024. A simple random sampling method was used to recruit 174 nursing students from three nursing institutions. Participants enrolled in the Geriatric Care MOOC via the Thai MOOCs platform. Data collection instruments included a personal information questionnaire, a knowledge test, an online learning behavior questionnaire, and an online learning satisfaction questionnaire. The experimental tool was the Geriatric Care MOOC on Thai MOOCs. Personal information, online learning behaviors, and online learning satisfaction were analyzed using descriptive statistics. Knowledge scores before and after the online course were compared using a Wilcoxon signed-rank test, with statistical significance set at p < .05.
The research findings revealed:
1.
Nursing students' knowledge scores after completing the Geriatric Care MOOC via the Thai MOOCs platform were significantly higher than before the course, with statistical significance (Z = ?11.416, p < .001).
2.
Nursing students' behaviors toward the Geriatric Care MOOC via the Thai MOOCs platform were at a frequent practice level (mean = 4.21, SD = 0.82).
3.
Nursing students' satisfaction with the Geriatric Care MOOC via the Thai MOOCs platform was at the highest level (mean = 4.62, SD = 0.42).
These findings suggest that the Geriatric Care course delivered via the Thai MOOCs platform could enhance students' knowledge. Therefore, it should be integrated into regular teaching and learning strategies to promote academic achievement and increase student satisfaction.
