Utilizing a sequential exploratory mixed-methods design, this study investigated the effects of flipped classrooms on Iranian EFL learners’ vocabulary learning. Thirty Iranian EFL learners, who were enrolled in an upper-intermediate class at a private language school in Iran, were randomly divided into two groups: the experimental group (the flipped learning group) and the control group (the traditional learning group). Pre-tests and immediate post-tests were administered via the DIALANG online diagnostic test which was also utilized to assess the learners’ current vocabulary level to explore the effects of flipped classrooms on the learners’ vocabulary learning. Semi-structured interviews along with students’ weekly journals were used to collect the qualitative data. The results of paired- and independent-samples t-tests showed that the experimental group performed better in the post-test both compared to their pre-test and the control group’s post-test. Thematic analysis of the qualitative data indicated that the flipped classroom enhanced the experimental groups’ knowledge of vocabulary, class participation, interaction, and engagement, although some of the participants were not accustomed to such an instructional method and preferred being instructed by the teacher and do the activities individually in the classroom. The study implications will be discussed.
