Application of PBL Combined With CBL Teaching Method in Experimental Teaching of Breast Imaging Diagnosis
Objective To explore the value of problem-based learning(PBL)combined with case-based learning(CBL)in the experimental teaching of breast imaging diagnosis. Methods A total of 96 students majoring in imaging diagnosis in Zunyi Medical University from March to June 2022 were selected as the research subjects,and they were divided into control group and experimental group according to random number table method,with 48 students in each group.The experimental group used PBL combined with CBL teaching method,while the control group used traditional teaching method.After class,questionnaire survey combined with performance assessment was used to comprehensively evaluate the teaching effect.Results The feelings of the experimental group towards the classroom were higher than those of the control group,including stimulating learning interest,improving literature retrieval ability,cultivating teamwork ability,improving problem-solving and imaging diagnostic thinking ability,and overall satisfaction(91.7％vs.72.9％;72.9％vs.41.7％;81.3％vs.56.3％;79.2％vs.54.2％;87.5％vs.68.8％;83.3％vs.64.6％),and the differences were statistically significant(P<0.05).The theoretical examination,film reading skills assessment,and total scores of the experimental group students were higher than those of the control group[(43.13±2.18)points vs.(41.42±2.48)points;(44.96±2.28)points vs.(40.21±2.55)points;(88.08±4.00)points vs.(81.63±4.45)points],and the differences were statistically significant(P<0.05).Conclusion The teaching method of PBL combined with CBL is effective in the experimental teaching of breast disease imaging diagnosis,which is a teaching mode worth trying.
