Implementation of Duolingo Application in Enhancing Vocabulary Skills of Fourth-Grade Elementary Students at SDN Ngadirejo 5

Abstract

This study investigates the implementation of the Duolingo application to improve English vocabulary acquisition among fourth-grade students at SDN Ngadirejo 5 Kediri. Vocabulary is a foundational component of language learning, particularly for young learners who are at the initial stages of their linguistic development. Using engaging and accessible tools like Duolingo can help to reinforce vocabulary learning in a fun and effective way. This research aims to assess Duolingo’s effectiveness in enhancing vocabulary retention, word recognition, and usage skills among elementary school students. This study follows a quantitative approach, involving pre-tests and post-tests to measure vocabulary improvement before and after a structured eight-week intervention period using Duolingo. The sample consists of 30 fourth-grade students who will engage in 15-minute daily practice sessions on Duolingo, focusing specifically on vocabulary-building activities. Results are anticipated to demonstrate measurable vocabulary improvements and to highlight the potential of gamified applications in supporting vocabulary acquisition for young learners. This study aims to contribute to the growing field of technology-assisted language learning in primary education and offers insights into best practices for integrating language-learning apps into elementary curricula.
