Application of the Combination of 3D Printing Technology With CBL and PBL Teaching Method in Medical Imaging Teaching of Head and Neck Diseases
Objective To explore the teaching effects of 3D printing technology combined with case-based learning(CBL)and problem-based learning(PBL)teaching method in imaging teaching of head and neck diseases.Methods A total of 47 senior undergraduates who studied medical imaging diagnostics in Guangxi Medical University from September 2021 to January 2022 were selected as the study subjects and divided into two groups using a lottery method.In the experimental group,3D printing technology combined with CBL and PBL teaching methods was adopted for image internship teaching,while the control group used CBL and PBL teaching methods only for image internship teaching.A questionnaire survey of classroom teaching effects was subsequently carried out,and students were asked to take professional theory tests and assessments of case film reading.An analysis was made on the differences between the two groups of students in the parameters of teaching effects(anatomical understanding,learning interest,knowledge understanding and degree of mastering,overall satisfaction of the course,etc.),theoretical examination results and case film reading assessment results.Results The overall classroom satisfaction score of the experimental group was(8.50±0.72)points,the professional theory score was(92.5±5.32)points,and the case film reading score was(87.08±5.50)points,which were higher those in the control group[the overall classroom satisfaction score was(7.22±0.79)points,the professional theory score was(87.17±6.18)points and the case film reading score was(77.83±5.61)points],the differences were statistically significant(P<0.05).Conclusion The application of 3D printing technology combined with CBL and PBL teaching methods in the image teaching of head and neck diseases can achieve good results and can effectively improve the teaching quality,learning interest and course satisfaction.
