2.2.4 Assessment of student learning effectiveness

In the pre-test, the trainees had not learned the ultrasound technique, and therefore item 2—"Ultrasound operation skills" was not included for evaluation on the DOPS form. The average DOPS score in the pre-test was 3.0 0.6. After the 16 trainees had attended the four classes, the average post-test score, which included item 2, was 3.8 0.3. The Mann-Whitney U test (two-tailed) showed that the scores differed significantly between pre- and post-test (P < 0.05; Table 4). Overall, the use of ultrasound effectively helped the trainees to avoid the complication of pneumothorax when performing acupuncture at the GB21 acupoint.
