To explore the peer assisted learning approach combined with microteaching in anesthesia intership for oversea students. Methods: 60 international medical students were randomly divided into two groups

Students in the control group have peer guidance before routine theatre observation

while students in experimental group discuss microteaching of anesthetic skills with each other by watching real time videos from smart phone

.Students’subjective attitude to new approach were evaluated and their final exam score were analyzed.SPSS 11.0 was used for data processing and the data was made descriptive analysis

t test and analysis of variance.Results: Students in experimental group did better in both theory exam （46.8±4.03）vs（35.7±6.12）and practice exam（35.2±3.20）vs（27.6±4.71） than those in control group

total scores of two groups were （80.5±7.40）and（63.1±6.81）respectively

these scores all had significant difference between two groups;More students from experimental group than those from control group feel interested in anesthesiology（P<0.01） and feel confident about exams（P<0.05）;There was no difference between two groups in understanding clinical guideline（P=0.57）.Conclusion: Peer assisted learning combined with microteaching is proved to enhance the quality of anesthesia teaching during internship for oversea undergraduates.
