［Abstract］ Objective To explore the effect of PBL teaching method based on web applied to the electrocardiography(ECG) teaching. Methods 100 clinical medical students from Grade 2014 were elected and divided into two groups equally. The control group ( 50 people) received traditional methods in ECG teaching

and the WPBL teaching method was conducted in experimental group ( 50 people). The effect of ECG teaching in two groups were evaluated and analyzed by test scores and questionnaire survey . Continuous variables were expressed as mean± standard deviation and were compared using t-test. Categorical variables were expressed as counts and percentages. Counting data were test by Chi-square. P value＜0.05 was considered statistically significant. All analyses were performed using the SPSS software package version 19.0.Results Comparing with control group

students in the experimental group performed better on practical understandings

interesting of learning ECG

presentation skills and team cooperation（p<0.05）. The average experimental score in the experimental group was higher than that in the control group[（32.91?3.56）vs.（27.38?4.63）

p<0.05]. There were no significant differences of theoretical scores between the two groups[（54.16?3.87）vs.（52.84?4.56）

p>0.05]. Conclusion The new form of WPBL teaching method can improve the efficiency of ECG teaching by emphasizing on a students-orientated way.
