Ortaçtepe, D.Akyel, A.

Data came from a Teachers’ Background Questionnaire, English Teachers’ Sense of Efficacy Scale (Chacon, 2005), Communicative Orientation of Language Teaching (COLT; Spada & Fronlich, 1995), and € the questionnaire version of COLT. Fifty Turkish EFL teachers working in eight schools responded to the questionnaires, and 20 of them were observed. The findings indicate that after the in-service education program, the teachers not only improved their practice of CLT but also became more efficacious. The findings highlight the importance of awareness-raising activities for professional development programs as well as the need for multiple instruments to analyse the extent to which teachers’ self-reported beliefs and practices concur with their observed teaching practice.EnglishArticle10.1002/tesj.185
