RESUMO
Objective To explore the effect of virtual laboratory (VL) + flipped classroom in teaching of virus infection diagnosis.Methods 40 students of Class One from clinical medical undergraduates of Grade 2014 were randomly taken as the experimental group,with 40 students of Class Two as the control group.The experiment group adopted flipped classroom teaching by virtual lab platform and classroom activities,while the control group adopted traditional classroom teaching such as watching video and lecturing.Finally post-test scores were compared by the independent samples t-test of SPSS 18.0 statistical software between the two groups.The teaching effects were evaluated through questionnaires survey in experimental group.Results The scores (82.73 ± 2.62) of comprehensive assessments were superior to the control scores (57.94 ± 4.65).Difference between the two groups was statistically significant (t=29.380,P=0.000).Students' satisfaction concerning the teaching methods and effects of the flipped classroom in experimental group was up to 85％.Conclusion Flipped classroom based on internet virtual lab platform in teaching of virus infection diagnosis can enhance the teaching quality and improve students' learning enthusiasm and thinking ability.
RESUMO
The experiment contents were integrated into three parts such as basic skills and verification experiment, systematic experiment and designing experiment. Basic skills and confirmato-ry experiments were performed alone with theory teaching by combination of modern teaching methods and traditional teaching methods, which consisted of “speaking”(experimental principles, methods and main technical points using multimedia), “looking”(demonstrating related operation on teaching website), teachers' demonstration, students' doing experiment independently and summarizing. In this part, the experimental operation skills such as the sterile operation technology, staining technology, microscopy technology and pure culture were emphasized. Systemic experiments would be carried out after completion of the most theory, the experiment time could be adjusted according to the experiment content, and the PBL teaching method was taken in this stage. After the theory teaching of Medical Microbiology was finished, students voluntarily participated in design experiments in the last stage, which were the fusion of scientific research subject and the experimental teaching. From the preview experiment, experiment operation, experiment report, to the final test, the multi-dimensional evalua-tion was implemented throughout the course of experiment teaching.
