Abstract
This study investigates the impact of implicit and explicit vocabulary instruction on Iranian EFL learners’ speaking proficiency within a flipped classroom context. Sixty male and female learners, aged 14 to 17, from the Iran Language Institute in Tehran (the capital of Iran), participated in the study. Following a general English proficiency test, participants were divided into two experimental groups: one received implicit vocabulary instruction, and the other received explicit instruction. Speaking proficiency was assessed through pre- and post-intervention oral tests. Data analysis was conducted using SPSS version 22. The findings indicate that flipped instruction significantly enhanced learners’ speaking skills. Additionally, both implicit and explicit vocabulary instruction positively influenced speaking proficiency; however, explicit instruction yielded greater improvements. These results suggest that integrating innovative instructional methods, such as flipped learning combined with explicit vocabulary teaching, can effectively support EFL learners’ oral language development. The study offers practical implications for curriculum developers and language educators seeking to optimize vocabulary instruction strategies in communicative language teaching to enhance educational quality.
