LBL-CBL-PBL-TBL四种教学法在医学检验专业实习过程中的应用价值

Application of LBL-CBL-PBL-TBL teaching methods in internship of laboratory medicine

目的评估LBL-CBL-PBL-TBL四种教学法在医学检验专业实习生实习过程中的应用价值。方法收集2017年5月1日至2018年5月31日在昆明市第三人民医院检验科实习的92名医学检验专业的实习生,随机分为A(30人)、B(31人)、C(31人)三组,A组采用LBL+CBL教学模式进行带教;B组采用LBL+CBL+PBL教学模式进行带教;C组采用LBL+CBL+PBL+TBL教学模式进行带教;实习结束前进行出科理论知识和实践技能操作考试,对实习生学习兴趣、对当前教学模式认可程度、实习生对带教教师教学水平评价等方面进行问卷调查,量化考核指标分析对比三组不同教学模式带教下学生的学习积极性、分析解决问题能力、自主学习能力、实践操作能力及对带教教师教学水平评价等。结果B组和C组实习生理论知识和技能操作考试总成绩(86.56±4.18)分、(87.50±3.89)分均高于A组(81.53±3.71)分(P<0.001),A、B、C三组实习生对带教教师教学水平评价得分差异无统计学意义(P>0.05),但C组实习生的学习积极性得分、分析解决问题能力得分、及对当前教学模式认可程度和满意度得分均高于A组和B组,差异有统计学意义(P<0.001)。结论LBL-CBL-PBL-TBL联合应用的教学模式有助于提高医学检验专业实习生的学习积极性、学习能力、技能操作能力。

Objective To evaluate of the application value of LBL-CBL-PBL-TBL teaching methods in the internship of laboratory medicine.Methods 92 medical laboratory interns in the laboratory of Kunming Third People’s Hospital during May 1,2017 to May 31,2018 were randomly divided into three groups:A(30 interns),B(31 interns)and C(31 interns).Group A adopted LBL+CBL teaching mode;group B adopted LBL+CBL+PBL teaching mode;group C adopted LBL+CBL+PBL+TBL teaching mode.Examinations of theoretical knowledge and skill operations were conducted before the end of interns to investigate the learning interest,the recognition degree of the current teaching mode,and the evaluation of instructor’s teaching level.And then the learning enthusiasm,the problem-solving ability,the autonomous learning ability,the practical ability,and the evaluation of instructor’s teaching level of the interns from the three groups of different teaching modes were analyzed and compared by using quantitative assessment index.Results The total scores of theoretical knowledge and operation skills of interns in group B(86.56±4.18)and group C(87.50±3.89)were higher than those in group A(81.53±3.71)(P<0.001).There was no significant difference in the scores of instructor’s teaching level evaluation among group A,B and C(P>0.05).However,the scores of learning enthusiasm,problem-solving ability,and recognition and satisfaction with current teaching models in group C were significantly higher than those in group A and group B(P<0.001).Conclusion The teaching mode of LBL-CBL-PBL-TBL combined application is helpful to improve the learning enthusiasm,the learning ability and the skill operation ability of medical laboratory interns.
