The Application of Case-Based PBL Teaching in the Teaching Reform of Interventional Radiology
Objective To explore the application value of problem-based learning(PBL)associated with case-based teaching in the educational reform of interventional radiology.Methods A total of 84 undergraduate students majoring in imaging in 2020 from March to June 2020 were selected as research objects,and they were randomly divided into test group and control group.Each group was consisted of 42 students.The control group used traditional teaching method;the test group applied the PBL teaching based on case.After the course,the basic theoretical knowledge and clinical cases of the two groups were analyzed,and the teaching satisfaction was evaluated by questionnaire survey.Results In the assessment of basic theoretical knowledge,the basic assessment scores of interventional radiology in the test group were(43.47±5.28)points and the results of interventional radiology diagnosis and treatment were(40.59±4.84)points,which were higher than those in the control group[(38.41±6.22)points,(35.18±5.67)points],and the difference was statistically significant(P<0.05).In the comprehensive analysis and assessment of clinical cases,the score of test group about the treatment options[(18.21±1.76)points],interventional surgery related[(27.12±2.76)points]and disease management performance[(26.61±3.14)points]were better than those of the control group[(15.21±2.62)points,(23.62±3.93)points,(23.12±4.46)points],and the difference was statistically significant(P<0.05).The questionnaire survey statistics showed that the satisfactory evaluation of the test group was higher than that of the control group in terms of interest improvement(97.62%vs.78.57%),self-learning ability(100%vs.83.33%),communication and collaboration ability(95.24%vs.73.81%),and clinical logic analysis ability(100%vs.80.95%),and the difference was statistically significant(P<0.05).Conclusion The application of case-based PBL teaching in the educational reform of interventional radiology can improve enthusiasm of students for independent learning and cultivate clinical thinking.In traditional teaching,simple memory of students of teaching content is transformed into understanding and application of knowledge,and then creative thinking is formed.
