The teaching effect was compared with that of undergraduates enrolling in 2010 who got conventional teaching. And the attitude to new teaching methods was investigated. Results The final theory test scores of two groups show no statistical significance（P>0.05）. Performance in the class of undergraduates enrolling in 2011 was better with statistical significance（P＜0.05）.Their attitude towards the new teaching method was satisfied.
