ABSTRACT

Objective To study on the application value of flipped classroom and PBL in the teaching process of sanitary chemistry experiment. Methods 112 students studied in School of Public Health in Nanchang University were considered as research subjects, including Preventive Medicine grade 2014 class 1 (observation group, n=57) and class 2 (control group, n=55). The students were taught with flipped classroom model in the control group , while flipped classroom combined with PBL was applied in the observation group. The learning effect of the two groups was evaluated by using the form of "Richter score scale"in the self-made form. The data was input using Epidata 3.0 and processed by SPSS 18.0, and it was analyzed by t test and 2 test. Results The evaluation index scores (learning attitude, ability improvement, learning cooperation, professional quality improvement) in the observation group were significantly higher than that of thecontrol group (P<0.05). Besides, the final test scores were also significantly higher in the observation group than those in control group [(83.56 ±10.81) vs. (69.37 ±10.45), t=7.059, P=0.000]. Conclusion Combining flipped classroom with PBL in the teaching process of sanitary chemistry experiment for the students majored in Preventive Medicine not only improves students' exam results, but also helps students improve their learning attitude, learning ability, professional quality and so on. Therefore, the teaching method is worthy of wider application.
