To explore the role of interactive practice teaching in improving the interventional ultrasound ability of students under military post education . We selected 31 students in grade 2015 were dividedin 2015. We divided these students into two groups randomly: interactive practice teaching group(16 students) and traditional teaching group(15 students). Effectiveness was evaluated at the end of 4 weeks learning. Compared with the control group, the interactive practice teaching group have a better grasp of the theoryetical knowledge and operation skills (P<0.05). The interactive practice teaching has effectively stimulated the learning interest of learning the interventional ultrasound, which also can improve the professional practice ability significantly.
