Despite various calls for a thorough re-conceptualization of current English language teaching (ELT) practices, incorporating courses for critical perspectives on linguistic and cultural diversity is still a major challenge in most teacher education programmes in many English as a foreign language (EFL) countries. Therefore, we explored the evolving perspectives of English as a global language among Turkish pre-service English teachers (PELTs) in response to a global Englishes-focused curriculum. Using self-report data, the study reveals participants' complex and diverse views on language varieties in English as a Lingua Franca (ELF) communication, driven by various reasons. After a GE-oriented course, most participants shifted to plurilithic orientations as they softened their beliefs in native-speaker English superiority and developed a more sophisticated understanding of English. Seven participants with monolithic orientation appeared to reduce the complex and dynamic nature of language to racialized stereotypes associated with native speaker norms. Based on the findings, how language orientations and ideologies may inform teacher preparation in language teaching was discussed. Several recommendations for further research and preparation of PELTs were made.
