Effects of Using Quizizz on Vocabulary Acquisition of Vietnamese EFL Young Learners

Numerous studies substantiate the positive impact of digital platforms in English language learning, particularly vocabulary acquisition. Digital technology like Quizizz within language learning contexts has indicated that integrating emerging technology into English vocabulary acquisition effectively scaffolds language mastery. This study investigated the effects of using Quizizz on young learners' vocabulary acquisition of Vietnamese English as a Foreign Language (EFL). In particular, the study attempted to find out the effects of Quizizz on the vocabulary acquisition of young EFL learners and identify their perceptions of using Quizizz on their vocabulary acquisition. The study's data were collected through vocabulary pre-test and post-test for the first variable and a 25-item questionnaire for the second variable. The study participants were 34 learners at the Key English Test (KET) 4 level in a foreign language center in the Mekong Delta of Vietnam. The research encompassed 17 students in the experimental group (EG) and 17 in the control group (CG). After the intervention, although students in both groups improved their vocabulary acquisition, the participants in the experimental group achieved significantly higher scores than those in the control group. Moreover, the questionnaire findings showed that young Vietnamese EFL learners in the experimental group had more positive perceptions of teachers using the digital platform for their vocabulary review. Based on the results gathered, the study recommends that teachers use technology to design activities to teach vocabulary to young learners. Finally, some implications and recommendations are also included.
