INTRODUCTION English is an international language used to communicate between various countries around the world. for this reason. English needs to be taught from an early age among children, moreover many children are still weak in English. Many children whose knowledge of English is still lacking even though it has been taught since first grade in elementary school, they think that English is difficult to learn. Improving English skills can be started with the smallest thing, namely vocabulary. Having a lot of English vocabulary will make it easier to improve children's learning abilities. JETLING (Journal of English Teaching and Learnin. | 54 Jumariati . said that student will improve much if they learn more words. Without mastering the vocabulary of the target language, it will be difficult for learners to understand the language where they need to hold an oral or written conversation, to comprehend a text, even to compose a text. Based on observations and interviews, the teacher said that vocabulary was something that was difficult for students to understand. When the researcher observes to class, teacher only learns in the usual way, such as writing material on the blackboard, writing questions and answering questions, and this method is relatively monotonous for elementary school Copland . stated that "children are more interested in learning language in an environment that is attractive and tends to be informal". One of the attractive and informal ways of learning English is through the media of educational games through smartphone or mobile phones. As mobile phones are practically ubiquitous (Burston, 2. , people now have smartphones for everyday tasks and are used by people of all ages, including with children in education. However, the use of technology in teaching and learning processes is still lacking despite its potential in helping students to develop their skills and learn new vocabulary from foreign languages, especially English. Connolly et al. proposed an idea for educators to integrate smartphones as a tool in learning foreign languages by using gamification. It is the use of game-like elements into non-game contexts to enhance user engagement and improve user experiences (Gianneto et al, 2. The integration of gamification in the educational system aims to render the learning process more captivating and enjoyable for students. Investigations have widely undertaken concerning the use of technology for learning, primarily on gamification's effects (Bal & Bicen, 2. Munday . argues that this application has the aim to teach vocabulary and grammar, even this application present combined activity between the skills in word pronunciation and translation and provides the activity of recognizing word from the picture, writing down what is heard, and others. According to Normadewi . , the definition of perception is an activity involving cognitive processes of making sense of an environment containing objects, symbols, or signs. Perception can be described as a person's expectations of objects such as persons, institutions, and institutions. (Akbar 2. states that those who want to know what the community wants and expects from an institution can do so by knowing the community's perception of the Knowing an individual's perception is a factor in supporting quality improvement According to Laufer . , vocabulary learning is central to language learning and It gives the language its essence. Without vocabulary, speakers of a particular language cannot convey meaning or communicate with each other. As Edward said, vocabulary is an important aspect of language teaching: "Vocabulary is an important element in all language According to Thornbury . , vocabulary refers to words or terms that have meaning in it. Without knowing the word meaning, the speakers cannot understand any information given. Regarding vocabulary knowledge.

However, in this research, only focused on one sub-aspect of each. They cover Form . Meanings . and Use . rammatical functio. Teaching is the process of transferring knowledge and some information to students. In teaching vocabulary in elementary school, the teacher must make students have many JETLING (Journal of English Teaching and Learnin. | 55 words and know their meaning by using creative and innovative strategies. As Cameron . 1: . explains that one of several ways of teaching vocabulary is to include structured opportunities for students to make predictions about the meaning of new words when they read a text. Teaching vocabulary is related to knowing the meaning of words. The teacher must teach words related to students' lives by using appropriate strategies, media, techniques. Teachers have to adjust it based on the level of students. Game is an ambiguous term and different game formats have been used by researchers and educators (Hanghyj, 2. Gamification of education is a developing approach for increasing learnersAo motivation and engagement by incorporating game design elements in educational environments (Ilaria Caponetto, 2. Developing approach is a method used to create and evolve the product, service, or result during the project life cycle. Gamification can be defined as the use of game elements in non-entertainment contexts to facilitate learning. The fact that games have many elements that are naturally appealing to teens and adults and have a strong impact on their lifestyle helps introduce additional learning Duolingo, a free language learning app developed by Luis Von Ahn and Severin Hacker, launched in November 2011, offering 68 different language courses in 23 languages, with 22 more in development is. Duolingo offers dictation, writing, and speaking practice for users who have reached a certain level. The application is available for iOS. Android and Windows Phone and is designed to help users improve their discussion skills anytime. Like a game, learning on Duolingo is designed to be engaging and easy to According to Munday . Duolingo has several effectiveness, as follow: Duolingo can be used to increase student activity in the language teaching and learning process. Duolingo has several fun features, so students donAot feel bored in the learning a language. It could be because Duolingo incorporates several aspects of gamification in learning, it can motivate and involve students in learning with Duolingo. The material learned for the game is usually difficult to forget, it could be because students happy to learn. Duolingo can make homework so that apart from studying in class. Duolingo can also support to train students to improve their vocabulary with Duolingo at their Based on the research conducted by Munday showed that if students 84,4% agreed that homework with Duolingo was better that other type of homework.
