In an era where technology seamlessly blends with teaching methodologies, this study examines EFL teachers’ perceptions in Saudi Arabia regarding the impact of blended learning methodologies on student engagement compared to traditional teaching approaches. This paper aims to explore the challenges these teachers encounter in implementing blended learning and its perceived effects on learning outcomes. Through a qualitative research design, the study engaged 42 EFL teachers, selected randomly to encapsulate a wide array of genders, academic backgrounds, teaching experiences, and levels of technological proficiency. A bespoke, researcher-developed questionnaire with open-ended questions was strategically employed to extract in-depth insights into the teachers’ experiences and perceptions regarding blended learning within the Saudi educational context. Thematic analysis was utilized to uncover patterns and themes within the responses. The findings reveal that while blended learning methodologies are recognized for their potential to moderately enhance student engagement through increased participation, attentiveness, and enthusiasm for learning, challenges significantly temper their effectiveness. These include technological barriers, disparities in digital literacy, and the complexities of integrating blended learning into existing pedagogical frameworks. Despite these obstacles, the study identifies a cautious optimism among EFL teachers about the potential of blended learning to enrich educational outcomes, provided that the aforementioned challenges are systematically addressed. This research is significant as it contributes critical insights into the evolving role of blended learning in EFL education, highlighting the need for strategic implementation and support mechanisms to fully leverage its benefits in enhancing student engagement and learning outcomes in Saudi Arabia. Based on these findings, implications, limitations, and recommendations were provided.
