Objective　To discuss the effect of the application of teachers as standardized pa-tients (TSP) in the teaching of diagnostics practice. Methods　It randomly selected 192 five-year un-dergraduate students of clinic department in 2011 grade

and divided them into experimental group and control group

each having 96 students.The control group used traditional teaching method (lecture-based learning

LBL)

while the experimental group used TSP teaching mode. Both groups were eval-uated by cases collection

cases analysis as well as professional quality

the physical examination

cases descriptions. Then the teaching effect was evaluated through practical skills assessment and perfor-mance in many aspects. In addition

the scores were made to be compared and analyzed with Mann-Whitney u mothed. Results　The TSP group got 69.66±4.15

17.78±1.39

27.10±1.68

47.83±4.92 respectively on the four aspects. It was superior to the LBL group(53.99±8.39

11.82±1.31，20.09±3.54

39.95±7.38) (P<0.01). In the cases description

the scores were 3.09±1.95

and there was no obvious difference with the LBL (2.63±1.53) (P=0.089). Conclusion　The application of TSP in diagnostics teaching practice can improve the teaching quality and competence

as well as train stu-dents' ability to analyze problems. And meanwhile

the TSP can develop the students' practice compe-tence and perfect the professional quality.
