ABSTRACT
Objective:
To investigate the application effect of 3D digital modeling combined with 3D printed model in assisting the classroom theoretical
teaching of
orthopedics in five-year undergraduate
students majoring in
clinical medicine.
Methods:
In May 2022, 33 five-year undergraduate
students majoring in
clinical medicine in the class of 2018 in Southwest Medical
University were selected and divided into experimental group with 17
students and
control group with 16
students according to the odd or even
student number. The
students in the experimental group were taught by traditional PPT+3D digital modeling combined with 3D printed model, and those in the
control group were taught by the traditional PPT
teaching method. The
teaching effect was evaluated by theoretical examination and a
questionnaire survey on the degree of
satisfaction with
teaching. SPSS 25.0 was used to perform the t-test, the
Mann-Whitney U test, the rank sum test, and the
chi-square test.
Results:
The experimental group had a significantly higher score of theoretical examination than the
control group (86.24±4.16 vs. 82.50±6.06). The
questionnaire survey on the degree of
satisfaction with
teaching showed that compared with the
control group, the experimental group had a significantly higher degree of
satisfaction with the
understanding and
learning of orthopedic
diseases [3 (2, 3) vs. 2 (2, 2), P < 0.05], the improvement in
learning interest [2 (2, 3) vs. 2 (1, 2), P < 0.05], classroom innovation [3 (3, 3) vs. 2 (1.5, 2), P < 0.05], and overall classroom
teaching [3 (2, 3) vs. 2 (2, 2), P < 0.05].
Conclusion:
In assisting the classroom theoretical
teaching of
orthopedics in undergraduate
students majoring in
clinical medicine, 3D digital modeling combined with 3D printed model can provide concrete 3D models, reduce the difficulties in
learning, improve the
awareness of orthopedic
diseases, strengthen
learning interest, and increase the degree of
satisfaction with
teaching and academic scores.
