In the treatment of diabetes, insulin therapy is becoming increasingly important. However, it is reported that insulin initiation is often delayed due to psychological resistance in patients and physician’s concerns about patient education. One of the reasons for this problem is medical doctors’ inadequate understanding of insulin self-injection and patients’ perspectives. Therefore, we introduced a new strategy for learning this more effectively. We set student doctors as target learners. The learning strategy consists of experiential learning through the use of insulin injection model, in-patient interviews, and small group learning. Our new practice seems to be useful to understand the perception gap between medical professionals and patients.
