Objective

2

To explore the application effect of case-based learning (CBL) combined with three-dimensional (3D) imaging technology in thoracic surgery probationary teaching.

Methods

2

Ninety thoracic surgery interns in the Affiliated Hospital of Yangzhou University

China in 2019 were selected and divided into the conventional theoretical teaching group (group A)

CBL group (group B)

and CBL combined with 3D imaging technology group (group C) according to the random number table method. Group A was taught with conventional theory; group B was taught by CBL; in group C

3D imaging software was used to reconstruct computed tomography data based on CBL. The theoretical scores of the three groups were evaluated respectively

and a questionnaire survey was conducted on the students (including whether the teaching is conducive to stimulating the interest and enthusiasm of learning

whether it is conducive to the establishment of clinical thinking

evaluation of advantages and disadvantages of the teaching method

and whether the teaching method is conducive to the mastery of theoretical knowledge). SPSS 20.0 was used for analysis of variance

t

test

and Chi-square test.

Results

2

The theoretical score of group A (85.83±4.62) was the lowest

and the theoretical score of group B was significantly lower than that of group C (89.71±5.84 vs. 94.60±6.28); the answer time of group C (286.68±77.56 seconds) was the shortest

and the answer time of group B was significantly shorter than that of group A (359.78±80.55 vs. 423.31±83.53 seconds

P

<

0.001). Group C was significantly better than group B and group A in the aspects of stimulating interest and enthusiasm in teaching

conducive to the establishment of clinical thinking

advantages of the teaching method

and conducive to the mastery of theoretical knowledge

and group B was significantly better than group A (

P

<

0.001).

Conclusion

2

The combination of CBL and 3D reconstruction technology improves the recognition of thoracic surgery interns to the teaching method

increases their theoretical scores

stimulates their learning interest and enthusiasm

cultivates their clinical thinking

and enhances their mastery of theoretical knowledge.
