The effect of spaced E-Learning on knowledge of basic life support and satisfaction of nursing students: a quasi-experimental study

Cardiopulmonary resuscitation (CPR) training is essential for all students, especially nursing students. One of the educational approaches to creating long-term learning in inclusive is spaced learning. Spaced learning consists of three or more training sessions in which information is presented over time and at intervals. The present study was conducted to investigate the effect of basic life support (BLS) training through spaced E-learning on the knowledge and satisfaction of nursing students.

In this quasi-experimental study with two groups, 106 undergraduate nursing students of Alborz University of Medical Sciences in Iran participated. The control group (n = 47) received BLS training with massed E-learning in one three-hour session, and the intervention group (n = 59) received spaced E-learning in three one-hour sessions. An electronic questionnaire including demographic information and a pre-test of BLS knowledge were sent to both groups. Also, immediately after receiving the training, two weeks later and one month later, they completed a post-test of BLS knowledge. Students were asked to indicate their level of satisfaction with the provided education by completing the SLS-OLE.

The post-test scores immediately after, two weeks later, and one month later of the intervention group were higher than the control group. The results of repeated measurement ANOVA showed that the score changes of knowledge are significant over time (p < 0.001), the number of sessions (p < 0.001), and the interactive effect of them (p < 0.001). There was no statistically significant difference in the level of satisfaction with education in both groups.

Based on the results, BLS training in both groups increased the knowledge of BLS. however, the increase in knowledge and its retention was higher in the intervention group that received the training in spaced learning.
