摘　　要：目的评价微课结合以问题为基础的学习(problem-based learning,PBL)在口腔正畸教学中的应用效果。方法将河南大学口腔医学院2014至2016级140名本科生作为研究对象,分为观察组和对照组,各70人。对照组实施传统教学方法,观察组实施微课结合PBL教学。比较两组理论知识、临床思维分析能力及操作技能。采用SPSS 18.0进行t检验和卡方检验。结果与对照组相比,观察组基础知识(83.67±5.73)分、病例分析(82.64±5.54)分、讨论与问答(81.57±5.06)分均高于对照组(72.36±5.41)分、(70.41±5.36)分、(69.37±4.48)分,差异有统计学意义(P<0.05)。观察组临床思维分析能力总优秀率为94.29%(66/70)、操作技能总优秀率为92.86%(65/70),均高于对照组75.71%(53/70)、74.29%(52/70),差异有统计学意义(P<0.05)。结论微课结合PBL教学在口腔正畸教学中的应用效果较好,可提高学生理论知识掌握度、思维分析能力及操作技能,使其将理论知识更好地应用于实际操作中,提升其综合素质。Objective To evaluate the application effect of microlecture combined with PBL on the teaching of orthodontics.Methods 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 andχ^(2) test.Results 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 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.
