In Indonesia, one of the foreign languages taught at the primary level (elementary school) and secondary level (junior and senior high school) is English. One effective learning medium used to teach English is Quizlet. However, the implementation of Quizlet for teaching vocabulary in elementary schools still needs exploration. Therefore, this research aims to investigate how elementary school teachers perceive Quizlet as a learning medium for teaching English and describe how Quizlet is implemented as a learning medium to teach vocabulary in the classroom. A descriptive qualitative method involves three elementary teachers through semi-structured interviews and class observations as data collection techniques. The findings indicate that teachers perceive Quizlet’s features, including flashcards, match games, and instant feedback, make teaching and learning more accessible, enjoyable, and engaging. However, teachers identified some challenges, including limited supervision, internet connectivity issues, varying technological understanding among students, and students’ motivation for independent learning. The vocabulary given is sourced from the school book and other materials. The SAMR model is applied, incorporating pre-, during-, and post-activities in the lessons. Quizlet’s features, including Flashcards, Learn, Write, Spell, Test, Match, and Live modes, are utilized both offline and online over two sessions. Despite internet connectivity challenges, students could navigate the various Quizlet modes, complete exercises, and achieve high scores. Overall, Quizlet is perceived positively by elementary teachers and has been successfully implemented as a learning medium for teaching English vocabulary.
