Comparison of the effect of different teaching modes in medical students′ education of cardiopulmonary resuscitation skills / 中国小儿急救医学

ABSTRACT

Objective:To explore the effect of different teaching modes in medical students′education of cardiopulmonary resuscitation(CPR)skills.Methods:One hundred and fifty college students were randomly allocated to classroom teaching group(G1=50), problem-based learning(PBL)group(G2=50) and computer-based teaching group(G3=50)from March to December in 2019.The students′acquisition and retention of theoretical knowledge and skills were assessed before(baseline)and after the teaching(immediately), then 2 months and 6 months later.Results:One hundred and fifty college students participated in the study.Among them, 84(56.0%)were male, with an average age of 23 years old.Sixteen students(10.7%)had participated in similar CPR training.There was no significant statistical difference in the demographic characteristics of students among three groups.At four time points including baseline, after teaching(immediately), 2 months and 6 months later, there was no significant difference in the theoretical examination results among three groups( P>0.05). But after teaching, the scores of each group were improved.At the second time point(after teaching immediately), each group had the highest scores( P<0.05). Compared the scores of the second point, the ones of the third time point(2 months later after teaching)and the fourth time point(6 months later after teaching)decreased, but there was no significant difference between the two time points( P<0.05). There was no significant difference in the pass rates of skill exam at the time point of baseline among three groups( P>0.05). The pass rates of G2 and G3 were significantly higher than those of G1 at 2 and 6 months later after teaching( P<0.05), but there was no significant difference between two groups.After teaching, the passing rate of each group was significantly higher than that of the baseline, and there were significant differences in the passing rates of any other time points after teaching, with the passing rate decreasing.Students′ feedback showed that all of them could clearly understand the teaching objective and accept the difficulty of the course, and PBL and computer teaching modes were more acceptable. Conclusion:PBL and computer-based teaching modes have better learning effectiveness and acceptance, which can be used as supplemental training to conventional classroom teaching or as strategies to consolidate learning.Two months may be the time point for retraining.
