ABSTRACT
Objective In this study,we aim to investigate and evaluate the application of peer education on the teaching of medical graduate students and to evaluate the teaching effect,in order to provide the basis for subsequent practice reform.Methods 49 graduate students majoring Internal Medicine-Pulmonology were randomly divided into traditional teaching(24) and peer education groups (25).We chose the primary culture technology of rat distal pulmonary arterial smooth muscle cells to be the teaching contents.For the traditional teaching group,we used the mode of class lecture giving and experimental skills learning under the assistance of the teachers; while in the peer education group,students benefited from the combination of class lecture given by the teacher and the seniors fixed teaching in which seniors help younger students.We selected the experimental operating time,cell purity and the practicing time to reach a standard culture as the evaluation indexes by filling a follow up questionnaire.The SPSS 13.0 was applied to the related data forx2 or t test.Results In the traditional teaching group,the average time to reach three times of standard culture was(3.2 ± 0.5) hour,which was(2.3 ± 0.4) hour in the peer education group.The cell purity was 80.1 ± 3.6％ in the traditional teaching group,while(85.4 ± 5.9)％ in the peer education group.The average practicing time was(6.3 ± 1.0) in the traditional teaching group,while(4.9 ± 0.6) in the peer education group.The peer education group master the teaching content better than the traditional teaching group (P=0.00).95.8％(23/24)of the students in the peer-education group considered the teaching contents simple,which was statistically higher(P=0.00) than traditional group (62.5％,15/24).Meanwhile,95.8％ (23/24)of the students in the peer-education group considered the teaching methods easy to accept,which was also statistically higher(P=0.02) than traditional group(70.8％,17/24).The difference was statistically significant (P=0.02).Conclusion The application effect of peer education is good and there is high degree of acceptance among the students.Besides,peer education accords with the medical postgraduate experiment teaching rules,and can cultivate medical graduate students' spirit of cooperation and communication ability in the process of implementation.
