以问题为导向的研讨式教学在医学影像学教学中的应用

目的探究以问题为导向的研讨式教学在医学影像学教学实践中的可行性及应用价值。方法将中南大学湘雅医学院2012级临床医学八年制64名学生,在医学影像学见习教学过程中随机分为两组:一组为传统教学组(32人),另一组为以问题为导向的研讨式教学组(32人)。学期结束后由第三方机构对两组学生进行理论测试及阅片能力考核;通过SPSS 20.0进行配对t检验。结果以问题为导向的研讨式教学组在理论测试中问答题及总成绩得分明显优于传统教学组(13.71±2.16)vs.(11.50±2.59),P=0.002;(79.88±4.70)vs.(74.29±5.16),P=0.0003];以问题为导向的研讨式教学组学生的阅片能力平均成绩优于传统教学组(87.92±8.46)vs.(80.83±6.86),P=0.003]。结论以问题为导向的研讨式教学较传统教学具有优势,能让学生获得更好的知识应用能力、综合分析能力及阅片思维能力。

Application of study-discuss teaching pattern guided by problem in the teaching of medical imaging

Objective To explore the feasibility and application value of the study-discussion teaching guided by problem in the teaching of medical imaging.Methods A total of 64 students from Grade 2012 of eight-year clinical medicine major in Xiangya School of Medicine were randomly divided into the traditional teaching group(32 students)and study-discussion teaching group(32 students).Theoretical examination and image-reading ability assessment in two groups were conducted by a third party;statistical analysis was performed by the paired t-test using SPSS 20.0.Results Scores of question-and-answer parts and total scores in the study-discussion teaching group were significantly better than those in the traditional teaching group(13.71±2.16)vs.(11.50±2.59),P=0.002;(79.88±4.70)vs.(74.29±5.16),P=0.0003].The image-reading performance in the study-discussion teaching group was better than that in the traditional teaching group(87.92±8.46)vs.(80.83±6.86),P=0.003].Conclusion The study-discussion teaching model based on problem is more effective than the traditional teaching model,which can help students enhance ability of knowledge application,comprehensive analysis,and image reading.
