Practical demonstration of X-ray film images for experimental teaching of the medical imaging technology in undergraduates

Objective To study the application value of practical demonstration of actual X-ray film images in the experimental teaching of radiography technology courses in medical imaging undergraduates. Methods A total of 63 medical imaging undergraduates of Grade 2015 were randomly divided into three groups to receive part of the experimental courses about chest and abdomen radiography examination. Their pre-class work and machine were the same. As the experimental group, group A and group B added demonstration with X ray film images, while group C (control group) did not. The different teaching effects of the two methods were evaluated by simulate practical assessment and quiz. The accepting degree of demonstration method was evaluated in accordance with questionnaire survey. Results The scores of simulated practical assessment (7.36±1.39) and quiz (4.24±2.01) in experimental group were significantly higher than those of (6.05±1.28) and (3.10±1.48) in the control group, with a statistically significant difference (P<0.01, P=0.024). Questionnaire survey showed that the experimental group were 100% accepted practical demonstration of X ray film images. Conclusion The application of practical demonstration of X-ray film images in radiology technology experimental courses can help undergraduates to accept new knowledge, deepen impression on knowledge and improve teaching effect, which is worth developing and popularizing.
