Abstract: Objective To evaluate the application of Visual slides in experimental exam of Histology. Methods Visual slides were used in addition to the picture of traditional slides and mixed slides during the experimental exam of histology for two years. Difficulty coefficient and discrimination index were calculated. Students’ scores of different parts were compared. Results Difficulty coefficient of visual slides is 0.67, higher than traditional slides and mixed slides (p<0.01). Discrimination index of visual slide is 0.51, higher the other two. Scores of visual slides appears moderate correlation with scores of theoretical exam. Conclusion These data indicates visual slides is worthy of use in exam because of its difficulty and good discrimination.

Key words: visual slide, histology, experimental exam
