MOOC+CBL教学在核医学SPECT/CT实习带教中的应用效果

Application effect of MOOC+CBL teaching mode in practice teaching of nuclear medicine SPECT/CT

目的探究大规模在线开放课程(massive open online course,MOOC)+案例教学(casebased learning,CBL)在核医学单光子发射型计算机断层显像仪(single photon emission computed tomography,SPECT/CT)实习带教中的应用效果。方法以2020年1月至2020年10月于武汉科技大学附属孝感医院核医学SPECT/CT进行实习的29名实习生为研究组,行MOOC+CBL教学;以2019年1月至2019年10月实习的31名实习生为对照组,行传统教学。实习结束前对理论及操作技能等进行考核;采用学习过程问卷(study process questionnaire,SPQ)、中文版评判性思维能力测量表(Chinese version of California critical thinking disposition inventory,CTDI-CV)评价其学习动机及思维能力;并比较两组学生对教学的满意度。采用SPSS 22.0进行t检验和卡方检验。结果研究组的理论知识、PET/CT病例分析及图像诊断成绩均高于对照组(P<0.05);研究组的表层动机、深层动机评分及SPQ总分高于对照组(P<0.05);研究组在开放思想、分析能力、系统化能力、评判性思维的自信心等方面的评分及CTDI-CV总分高于对照组(P<0.05);研究组对教学方式及自学能力增加的满意度高于对照组(P<0.05)。结论对核医学SPECT/CT实习生给予MOOC+CBL教学,可提高其考核成绩、学习动机及思维能力,并可增强其自学能力。

Objective To explore the application effect of massive online open course(MOOC)+case-based learning(CBL)in SPECT/CT practice teaching of nuclear medicine.Methods Twenty-nine interns of nuclear medicine SPECT/CT in Xiaogan Hospital Affiliated to Wuhan University of Science and Technology from January 2020 to October 2020 were selected as the research group and received MOOC+CBL teaching.Taking 31 interns from January 2019 to October 2019 as the control group,and the traditional teaching method was conducted.At the end of the internship,the students'theoretical and operational skills were assessed.Their learning motivation and thinking ability were evaluated by using the study process questionnaire(SPQ)and the Chinese version of California critical thinking disposition inventory(CTDI-CV),and the two groups'satisfaction with teaching was compared.SPSS 22.0 was used for Chi-square test and t-test.Results The results of theoretical knowledge,PET/CT case analysis and image diagnosis in the study group were higher than those in the control group(P<0.05).The total scores of surface motivation,deep motivation and SPQ in the study group were higher than those in the control group(P<0.05).The self-confidence scores of open mind,analytical ability,systematization ability,and critical thinking and CTDI-CV total scores of the study group were higher than those of the control group(P<0.05).The study group was more satisfied with the teaching and the enhancement of self-study ability than the control group(P<0.05).Conclusion MOOC+CBL teaching for nuclear medicine SPECT/CT interns can improve their examination results,learning motivation and thinking ability,and also enhance their self-study ability.
