The pandemic hits the world today has made educators and parents moved to develop attractive English learning media for young learners to keep them excited while learning from home. Android smartphone devices are currently popularly used for interaction media between young learners and teachers during learning from home. From this background, researchers developed English learning media using Augmented Reality that can be easily accessed from Android smartphone for young learners. This research focuses on creating learning media and English quizzes based on Android using Augmented Reality (AR) technology. The English materials used in this research are taken from Thematic English Learning 1 book from chapter 1 to chapter 5 and focused on enriching student's vocabulary. The AR application was made using Unity with the addition tool named Vuforia SDK. It is used to detect an image target so that the AR objects can be displayed throughout the screen. Vuforia SDK detects image target by comparing captured images with those stored in the database. This research resulted 24 threedimensional AR objects, 6 two-dimensional AR objects which are ready to be used as English learning media and 54 quizzes which are feasibly to evaluate students' skills after learning English through AR objects.

This research aims to investigate the effect of teaching English vocabulary to young learners via Augmented Reality learning media. The subject of this research was 12 students of grade 1 elementary school. Due to strict health protocols during COVID-19 outbreak, the testing phase was done in students' respective homes accompanied by their parents using cell phones. Vocabulary illustrated in 30 three-dimensional objects and their written form were generated through cell phone’s scanning. A quiz consisted of 54 multiple choice questions was provided after the interactive learning experience. Both the vocabulary and quiz were refer to Thematic English Exploration for Grade 1 book.
