Abstract

Vocabulary knowledge is central to EFL proficiency and academic success. Task-Based Language Teaching (TBLT) has been proposed as an effective approach to enhancing vocabulary acquisition and retention, yet its efficacy varies across contexts. This systematic review synthesizes empirical studies published between 2000 and 2025 to examine how TBLT impacts vocabulary learning in EFL settings, including Moroccan universities. Following PRISMA guidelines, the review identifies effective instructional strategies, highlights limitations, and provides pedagogical recommendations. Findings indicate that task-based, contextualized, and strategy-oriented instruction consistently improves vocabulary retention and meaningful use, while isolated or rote-based methods are insufficient. The study underscores the importance of integrated, research-informed models for higher education EFL instruction.
