Abstract
In digital learning, the use of an interactive eBook is perceived as helpful for students. However, the effect of interactive eBooks on learning among clinical nurses has not been explored yet. This study used an interactive electrocardiogram eBook to explore the effect of digital learning on the promotion of electrocardiogram interpretation competence, confidence, knowledge retention, and learning satisfaction among clinical nurses. A single-group quasi-experimental study with three repeated measures was conducted. A total of 80 nurses from the emergency room, critical units, and medical-surgical units completed the measures. The results showed that digital learning is an effective method that significantly improved nurses' electrocardiogram competence, learning retention, confidence, and learning satisfaction. Most nurses were satisfied with the convenience and content design of this eBook. Few nurses reported drawbacks regarding loading speed and individual learning habits. It is recommended that more preset learning exercise questions should be created for trial and error so that nurses can have repeated practice for self-assessment. Specific feedback mechanisms should be established to promote motivation for digital self-learning.
