Development and validation of a scale to probe into Iranian EFL teachers’ perception of problem-based learning: PBL Challenges in Focus

Problem-based language learning approaches can prove advantageous in fostering meaningful language learning and enhancing language proficiency. The present sequential explanatory mixed-methods study aimed to explore the perspectives of Iranian EFL teachers regarding problem-based learning (PBL), and the challenges they confronted in its application. To this end, forty male and female Iranian EFL teachers from high schools and language institutes in Alborz province were selected using convenience sampling. In the course of the study first, a questionnaire was employed to gauge teachers' perceptions of problem-based language learning. To collect the required data, the Teachers' Perceptions of Problem-Based Learning (TPPBL)questionnaire was developed and validated. Afterwards, an interview was conducted to triangulate the data and provide nuanced insights into the challenges faced in implementing PBL. The gathered data were analyzed both quantitatively and qualitatively. The findings unveiled that the participants held positive perceptions regarding PBL implementation in language classes. However, they addressed various challenges including role adjustment, inadequate training and experience, lack of suitable instructional materials, and time constraints while implementing PBL techniques. The implications of these findings extend to EFL teacher educators, teachers, learners, and researchers, offering valuable insights for enhancing language teaching practices and addressing challenges associated with PBL implementation.
