问题导向教学法在超声诊断学教学中的应用效果分析

Analysis of the Application Effect of Problem-based Teaching(PBL)in the Teaching of Diagnostic Ultrasound

目的探讨问题导向教学法(Problem-Based Learning,PBL)在超声诊断学教学中的应用效果。方法回顾性分析2019年5月—2020年12月齐齐哈尔医学院附属第三医院超声诊断学73名实习学生的资料,根据教学模式的差异分为常规教学组以及问题导向教学组,常规教学组35名采取常规的教学模式,问题导向教学组38名采取PBL的模式,比较教学后两组考核成绩、教学质量评分。结果问题导向教学组考核成绩优于常规教学组,问题导向教学组利于提高学习兴趣、利于提高自学能力、利于提高团结协作能力、利于提高思维能力评分均优于常规教学组,差异有统计学意义(P均<0.05)。结论在超声诊断学教学中引入PBL的效果显著,对提高教学质量、培养学生能力有促进作用。

Objective To explore the application effect of Problem-Based Learning(PBL)in the teaching of diagnos-tic ultrasound.Methods A retrospective analysis was conducted on the data of 73 cases of intern students in diagnos-tic ultrasound at the Third Affiliated Hospital of Qiqihar Medical College from May 2019 to December 2020.Accord-ing to the differences in teaching modes,they were divided into a conventional teaching group and a problem-oriented teaching group.The 35 cases in the conventional teaching group adopted the conventional teaching mode,and the 38 cases in the problem-oriented teaching group adopted the problem-based teaching method(PBL)model.The test sub-jects'assessment scores and teaching quality scores after teaching between two groups were compared.Results The problem-oriented teaching group had better assessment results than the conventional teaching group,the improved learning interest,self-study ability,unity and cooperation ability,and the improved thinking ability scores of problem-oriented teaching group were better than those of the conventional teaching group,and the differences were statisti-cally significant(all P<0.05).Conclusion The introduction of problem-based teaching(PBL)into the teaching of diag-nostic ultrasound has a significant effect.It has a promoting effect on improving teaching quality and cultivating stu-dents'abilities.
