Teachers’ teaching-learning conceptions and sense of selfefficacy are important constructs that can affect each other and directly influence the effectiveness of teaching. This study investigates the relationship between teachinglearning conceptions and sense of self-efficacy of preservice EFL teachers using a mixed-method research design. The quantitative data were collected from 374 4th grader pre-service teachers who were studying ELT in state universities. This study used the Turkish versions of the Teaching and Learning Conceptions Questionnaire and Teacher Sense of Efficacy Scale. Open-ended questions were used to gather qualitative data from 42 pre-service teachers who consented to respond. Descriptive statistical techniques and content analysis were used for the data analysis. The study found that teachers adopted a constructivist conception more than a traditional one. The results also suggest that the pre-service teachers have high level of self-efficacy beliefs. The results showed that preservice teachers' teaching-learning conceptions and sense of self-efficacy were related. High and positive correlations were found between their constructivist conception and efficacy for student engagement, efficacy for instructional strategies, and efficacy for classroom management. The preservice teachers felt efficacious in instructional strategies, student involvement, and classroom management. Their traditional conception is negatively correlated to their efficacy for student engagement.Taking the results into consideration, implications and suggestions were formulated for the main stakeholders of language teacher education.
