Results:The theoretical scores of the experimental group and the control group students were (84.37±10.45) vs. (81.44±9.22) ( t=2.68, P=0.008), and the experimental skills scores were (93.66±3.89) vs. (88.41±5.67) ( t=9.51, P<0.001). Questionnaire investigation showed that the students in the opening experimental group were more satisfied with the courses arrangement ( χ2=8.31, P=0.004), group cooperation ( χ2=21.10, P<0.001), assessment form ( χ2 =7.92, P=0.005), improvement of the writing ability of scientific research papers ( χ2 =17.56, P<0.001), improvement of practical skills ( χ2=11.70, P=0.001), logical thinking, language organization and expression ability ( χ2=10.33, P=0.001).
