This study investigated a new blended approach for enhancing vocabulary achievement. To this end, the project used a convenience sample of 50 intermediate EFL learners ranging from 19-35 years of age from three intact classes studying English translation at university. They were randomly assigned to two groups of 25 students each. In the experimental group, the treatment consisted of providing photos/cartoons related to the sessions’ course of instruction on Instagram, with the learners discussing and exploring the meaning of vocabularies via peer scaffolding using metacognitive strategies. The control group followed the syllabus and assigned homework according to the class program. To investigate the vocabulary achievement of the participants, a piloted multiple-choice vocabulary posttest was administered. The results that were analyzed through independent samples T-test revealed that the blended approach could significantly affect the performance of the experimental group. This study has implications not only for teachers, researchers, and syllabus designers but also for EFL learners with unpacking the notion of metacognition and peer scaffolding, proposing an integrated framework that illustrates how it may pervade the teaching-learning process as an educational goal. The implication of this study supports student responsibility, a student-centered classroom, and higher levels of cognition.
