Abstract

Abstract: Objective To evaluate the effect of teaching methods based on real-time audiovisual feedback in clinical training of cardiopulmonary resuscitation (CPR). Methods Totally 110 medical undergraduates were enrolled from Medical College of Jianghan University .The students were randomly divided into the experimental group (n=56) and the control group (n=54).The students in experimental group adopted the teaching method based on real-time audiovisual feedback and the control group adopted classic teaching method. Two groups of students conducted theoretical knowledge examinations, operational practice assessments followed by a questionnaires survey. The results of two groups were compared with the χ²test and the t-test in order to evaluate the effect of teaching methods in two groups. Results The theoretical test scores and skill test scores of the experimental group were (27.56±8.62) and (60.02±8.46), which were higher than those of the control group (24.75±8.96) and (53.72 ±9.59). The differences were all statistically significant (P<0.05).The results of the questionnaire survey from the teachers showed that the scores of student performance (4.78±0.63) and teachers' performance (4.80±0.47) from experimental group were significantly higher than those from control group (3.69±0.46 and 3.75±0.63 respectively).The satisfaction of the experimental group students with teacher teaching, self-performance and teamwork were (4.93±0.59),(4.70±0.71) and (4.59±0.63)respectively, which were all higher than those of the control group (4.02±0.73,3.85±0.69 and 3.26±0.56 respectively ). The differences were all statistically significant (P<0.05). Conclusions The teaching method based on real-time audio-visual feedback can help to improve the teaching effect of CPR practice and improve students' satisfaction with teaching, self-expression and teamwork.
