Purpose: To determine the impact of occupational socialization on eight South Korean teachers' interpretation and delivery of the Hanaro Teaching (HT) model. Method: Data were collected through formal interviews, film of teachers employing HT, document analysis, reflective journaling, and the critical incident technique. They were analyzed using analytic induction and constant comparison. Findings: The teachers interpreted and delivered the HT model in four different ways. These were the full and full+ versions of the model, watered down, and taking a cafeteria approach. The organizational socialization phase was key in shaping how the teachers delivered the model. The teachers' acculturation and professional socialization were mainly supplemental. Conclusions: The fact that seven of the teachers employed HT without any formal training suggests that the model was fairly easy to learn. Specific training in undergraduate physical education teacher education, however, could lead to more teachers employing the full and full+ versions of the model.
