In this study, we attempted to reveal, by analyzing the experience structure of ‘creating an impromptu play,’ that theater education in a competencybased curriculum can improve empathy. For this purpose, we looked at empathy. Empathy is the ability to understand others and is a concept that combines the cognitive element of being able to think from the other person's perspective and the emotional element of being able to feel the emotions of others. Empathy can be expressed through face-to-face social interaction experiences, as revealed by mirror neurons, so diverse direct experiences are of utmost importance. Based on this, the experience structure of ‘creating an impromptu play’ was divided into three stages and analyzed to be an experience structure that can promote empathy. The first step is ‘creating a story.’ This is a process that is premised on empathy from another person’s perspective, and when imagining a story, the body can promote empathy because it reenacts actions as if they were real. Since this process is structured through group cooperation, it can be analyzed as an immediate empathy training process from the perspective of others. The second step is ‘expressing roles.’ Depending on the body's operating principles, role experience can promote actions appropriate to one's imagination or fragmentary expressions can stimulate the rest of the body to provide sufficient role experience. Therefore, it is an experience structure that allows us to understand others in the most direct way. Additionally, since it is a face-to-face social interaction, you can practice empathy by experiencing the non-verbal behavior of others. The third step is ‘appreciating it as an audience member.’ Appreciation experience is an experience structure that allows one to escape the physical limitations of everyday life, understand others from their perspective, and internalize the life knowledge they have acquired through this, according to the body's operating principle of internal imitation. In this way, theater education has an experience structure based on empathy, so it can be an educational alternative for improving empathy in a competency-centered curriculum. By proving the value of theater education through this study, we hope that theater education will be more actively applied and expanded in various educational fields.
