The growing importance of global English has led to the rise of English for Specific Purposes (ESP) teaching, particularly in higher education. Despite the concurrently increasing demand for ESP teachers, pre-service teacher education programmes have largely neglected this important area. This study has been initiated to address the professional needs of future ESP teachers by designing an innovative ESP teacher education course in a teacher education programme in Turkey. The theoretical framework of the study is based on the constructivist perspective in order to help pre-service English teachers create meaning through their participation in various socialisation practices. The first part of the course was theory-informed to familiarise students with ESP-related topics, while the second part followed a practice-oriented approach. Data were collected through pre-and post-test open-ended questionnaires, student journals, and ESP projects. Content analysis was used to analyse the qualitative data. Findings underline the positive effects of the ESP course. Suggestions are offered for teacher education programmes.
