“…This study focuses on Quizlet, another very popular online educational platform (also available as a mobile application) that allows users (both teachers and learners) to create wordlists and their corresponding definitions or translations, and automatically generates interactive and dynamic selfstudy activities based on these wordlists. To date, several studies have investigated the potential benefits of using Quizlet for language acquisition, with a special interest in vocabulary development, for example with Japanese learners of EFL (e.g., Barr, 2016;Dizon, 2016), Indonesian (e.g., Setiawan & Wiedarti, 2020), Austrian (e.g., Platzer, 2020), Taiwanese (e.g., Chien, 2015), Thai (e.g., Waluyo & Bucol, 2021), Ukrainian (e.g., Chaikovska & Zbaravska, 2020;Novikova, 2019) or Vietnamese students (e.g., Nguyen et al, 2022). The present study seeks to analyze the effect of Quizlet on the vocabulary acquisition of Spanish EFL learners.…”
