Objective　Comparing with traditional teaching methods of oral histopathology

to probe whether the interactive teaching system of the digital microscope can improve the teaching effi-ciency of experiment of oral histopathology courses. Methods　The subjects were the 2010 grade students (40 students) and the 2011 grade students (38 students) majoring in stomatology of South Medical University

and they were evenly divided into 2 groups at random. In the first part of the ex-periment of Grade 2010

the teaching of traditional optical microscope was used in a group of experi-mental courses

and interactive teaching with digital microscope was used in the other group. In the second part of the experiment the two groups swapped the teaching method. While in the whole exper-iment of Grade 2011

traditional optical microscopes were adopted in one group

and in contrast

the interactive teaching system of the digital microscope was adopted in the other group. The P values of the 5 indexes were less than 0.05. After the courses

the 2010 grade students received the questionnaire survey and the 2011 grade students received the quiz about the experimental course

and then the evaluation results of the two groups were compared for t inspection

using SPSS software t test. Result　The questionnaire results of Grade 2010 showed that the scores of digital microscope interactive group were higher than those of traditional teaching group in satisfaction with teaching

teacher-student interaction

classroom atmosphere active degree

learning interest

and the understanding of the teach-ing content. The experiment course content test results of Grade 2011 showed that the digital interactive group students averaged 46.26

while the average score of the traditional teaching group was 42.78%. The difference between the two groups had statistical significance

P=0.001. Conclusion Compared with the traditional teaching methods

the interactive teaching system of the digital microscope can enhance the academic grades

improve the teaching efficiency of experiment of oral histopathology courses

and elevate the teaching quality.
