摘要
目的:探讨以问题为基础的学习(problem-based learning,PBL)结合标准化患者(standardized patient,SP)在眼科学基础教学中的应用效果。方法:选取2012级眼视光专业学生64人为研究对象,随机抽取32人为试验组,采用PBL结合标准化患者进行眼科学基础教学,其余32人为对照组,采用传统教学方法。授课结束后应用自制调查问卷调查学生对教学效果的评价。统计两组学生的考试成绩及问卷调查结果。计数资料采取χ2检验,计量资料采用均数±标准差(x珋±s)表示,行独立样本t检验,以P<0.05为差异有统计学意义。结果:试验组理论考试成绩(83.22±3.75)和试验考试成绩(94.28±2.20)均明显高于对照组理论考试成绩(70.72±3.95)和试验考试成绩(85.44±3.52),差异有统计学意义(P均<0.01)。试验组在实习考核中问诊及病史采集、眼科检查、临床诊断和病历书写的成绩均值均高于对照组,差异均有统计学意义(P均<0.01)。试验组学生对SP与PBL结合教学在调动学习积极性、加强团队协作意识、提高语言表达能力、综合分析能力、自学能力、创新能力、总结归纳能力、实践操作能力,以及加强知识结构系统化方面的效果评价明显高于对照组,差异有统计学意义(P均<0.05)。结论:眼科学基础教学中将SP与PBL相结合,有助于学生更好地掌握专业知识,能调动学习积极性,提高自学能力、实践操作能力和临床思维能力。
AIM:To investigate the effect of problem- based learning(PBL) combined with standardized patient(SP)in the teaching of basic science of ophthalmology.METHODS:Sixty-four students of Optometry in grade2012 were randomly divided into experimental group(n =32) and control group(n =32).Traditional teaching method was implemented in control group while PBL combined with SP was applied in experimental group.At the end of term students were interviewed using self-administered questionnaire to obtain their evaluation for teaching effect.Measurement data were expressed as x±s and analyzed by independent samples t test.Enumeration data were analyzed by x~2 test,and P<0.05 significantly statistical differences.RESULTS:The mean scores of theory test(83.22 ±3.75)and experimental test(94.28 ± 2.20) in experimental group were significantly higher than theory test(70.72 ±3.95) and experimental test(85.44 ± 3.52) in control group(all P < 0.01).The mean scores of diagnose inquiry,ophthalmologic examination,clinical diagnosis and medical record writing were higher than that in the control group,difference had statistical significance(P<0.01).The students in experimental group had a significantly better self- assessment than the control group in learning enthusiasm,consciousness of team cooperation,ability of language expression,comprehensive analysis ability,self- learning ability,innovation ability,summarizing ability,practice ability,and systematic knowledge structure.The differences were statistically significant in questionnaire between the two groups(all P<0.05).CONCLUSION:Using PBL combined with SP teaching mode in basic science of ophthalmology can highly improve learning enthusiasm of students and cultivate self-learning ability of students,practice ability and ability of clinical analysis.
