Examining the Effectiveness of Blended Learning Models in Enhancing English Language Proficiency and Student Engagement in Azerbaijani Higher Education

Abstract

Blended learning – the integration of online and face-to-face instruction – is increasingly adopted in higher education and has been termed the “new normal” in course delivery. This mixed-methods study investigates whether a blended learning model can enhance English language proficiency and student engagement more effectively than traditional in-person instruction in Azerbaijani higher education. Two groups of undergraduate English students (control with traditional instruction, n = 30; experimental with blended instruction, n = 30) participated over a 14-week term. Pre- and post-tests measured English proficiency (writing, grammar, vocabulary), and a post-intervention survey assessed student engagement (motivation, participation, and confidence). Additionally, focus group interviews provided qualitative insights. Results show that the experimental (blended) group achieved significantly higher gains in English proficiency (mean gain ≈ +18 points) compared to the control group (mean gain ≈ +8 points), and reported greater engagement across multiple dimensions (e.g. motivation and active participation). These findings align with prior research indicating blended learning’s advantages in improving language skills and fostering student involvement. The discussion draws on the Technology Acceptance Model (TAM) and Vygotsky’s Zone of Proximal Development (ZPD) to interpret results: students’ acceptance of the blended platform (ease of use and usefulness) supported their active engagement, and the blended approach provided scaffolding and interaction that extended students’ learning beyond the classroom. In conclusion, the study provides empirical evidence that blended learning can enhance English language proficiency and engagement in the Azerbaijani higher education context. The paper offers recommendations for implementing blended models in English language teaching (ELT), suggesting that universities invest in teacher training and technological infrastructure to maximize the benefits of blended learning for student success.
