[An introduction and implementation of problem-based learning for radiography positioning training].

The knowledge of radiological technologists is expected to increase with medical development. However, it is impossible to impart all knowledge in a limited time frame. Problem-based learning (PBL) is a learning methodology to solve it. In the PBL, students can gain problem-solving abilities by acquiring necessary knowledge from clinical cases and applying them during practice. We here report to implement the PBL in radiography practice. This practice opened a course at 2nd semester of third-grade students in our school. The practice flow includes presentation of clinical case and a survey of necessary knowledge, group work, radiography, reflection through practice, and deliberation of different cases. The clinical case was the radiography of an emergency patient. The evaluation items were about knowledge, skill, and attitude. By the PBL practice, students could realize a clinical scene, and discover considerable points unwritten in textbooks.
