Development and effectiveness of an E-book on cardiovascular examination for nursing students

Abstract

This research and development study aimed to: (1) develop and evaluate the efficiency of an E-Book on cardiovascular examination, and (2) examine its effectiveness by comparing learning achievement in knowledge and physical examination skills between an experimental group and a control group, as well as assessing students’ satisfaction with the E-Book. The study was conducted in two phases: Phase 1 involved the development and efficiency testing of the E-Book, while Phase 2 focused on testing its effectiveness. The sample consisted of 102 first-year nursing students at Rangsit University, with 42 students participating in Phase 1 and 60 students in Phase 2. Research instruments included the E-Book, a knowledge achievement test, a physical examination skills assessment, and a satisfaction questionnaire. Data were analyzed using descriptive statistics, the Mann–Whitney U test, independent t-test, and one-sample t-test.

The results demonstrated that the E-Book achieved an efficiency score of 82.5/84.5, exceeding the established 80/80 criterion. No significant difference was found in knowledge achievement between the control and experimental groups. However, students in the experimental group exhibited significantly higher physical examination skill scores than those in the control group (p < .001). Furthermore, students’ satisfaction with the E-Book was significantly above the 80% criterion (p < .05). These findings suggest that the E-Book is an effective supplementary learning resource in, suitable for both classroom instruction and self-directed learning.
