Objective

2

To evaluate the application effect of microlecture combined with PBL on the teaching of orthodontics.

Methods

2

One hundred and forty undergraduates from Batch 2014 to Batch 2016 of School of Stomatology

Henan University were randomly divided into two groups

with 70 undergraduates in each group. Traditional teaching method was adopted in the control group

while microlecture combined with PBL was used in the observation group. The theoretical knowledge

clinical thinking and analysis ability

and operational skills were compared between the two groups. SPSS 18.0 was used to conduct

t

test and

χ

2

test.

Results

2

The scores of basic knowledge [(83.67±5.73) points]

case analysis [(82.64±5.54) points]

and discussion and questions and answers [(81.57 ± 5.06) points] in the observation group were higher than those in the control group [(72.36±5.41) points

(70.41 ± 5.36) points

and (69.37±4.48) points

respectively]

with statistically significant differences (

P

<

0.05). The total excellent rate of clinical thinking and analysis ability and operational skills in the observation group were 94.29%(66/70) and 92.86%(65/70) respectively

which were higher than those in the control group [75.71%(53/70) and 74.29%(52/70)]

with statistically significant differences (

P

<

0.05).

Conclusion

2

The application of microlecture combined with PBL has good effect on the teaching of orthodontics

which can improve the mastery of theoretical knowledge

clinical thinking and analysis ability and operational skills of students

and make them better apply theoretical knowledge in practical operation

thus improving comprehensive quality.
