Development and Effects of Supplementary Textbook about EKG for Nursing Students
Purpose: The aim of this study was to develop teaching material of electrocardiography (ECG) education for nursing students. Teaching material was designed to increase ECG knowledge and self-confidence of nursing students.Methods: A convenience sample of 72 nursing students in a university of South Korea were recruited to an experimental group (n=36) or a control group (n=36). A non-equivalent control group pretest-posttest design was employed to test effects of teach material on ECG knowledge and self-confidence of nursing students. Teaching material was developed based on analysis learners, state objectives, select media & materials, utilize media & materials, require learner participation, and evaluate & revise (ASSURE) model. ECG knowledge and self-confidence were self-reported using scales developed by authors. Pre-test and post-test data were collected before and after a three-week intervention period.Results: The ECG knowledge of the experimental group was significantly higher than that of the control group (t=6.86, <i>p</i><.001). And the self-confidence of the experimental group was significantly higher than that of the control group (t=3.07, <i>p</i>=.003).Conclusion: Teaching material developed in this study was effective in improving ECG knowledge and self-confidence of nursing students. Thus, this teaching material could be used as supplementary textbook in diverse nursing practice education such as simulation or nursing skill training.
