One of them is learning English, before mastering English as a whole, they must learn vocabulary as a language foundation to express thoughts, feelings, provide information, share ideas, understand others and build social relationships through communication (Schmitt & Schmitt, 2020) . Learning vocabulary allows individuals to articulate their thoughts and depth of communications. In addition, in the aspects of providing information and sharing ideas, a strong vocabulary is crucial for conveying information accurately. Without adequate vocabulary, individuals may struggle to explain complex concepts or provide detailed descriptions, which can lead to misunderstandings (Alqahtani, 2015) . Vocabulary facilitates the sharing of ideas by providing the necessary words to express abstract concepts. This is particularly important in academic and professional settings where the ability to articulate ideas clearly (Cameron, 2001) .  \nAccording to Apoko et al. (2023) in learning English one needs to have qualified vocabulary knowledge. It is stated by Jaelani & Sutari (2020) that a person cannot interact with his environment if he does not possess a larger vocabulary, and without vocabulary will be a barrier for them to express themselve in writing and speaking, and also make them lose motivation when listening and reading. According to Ajisoko (2020), vocabulary cannot be separated from other aspects of English  \nlanguage learning. As stated by Schmitt & Schmitt (2020), before learning additional language abilities like speaking, listening, reading, and writing, students must first understand the fundamentals of vocabulary. Before EFL students wish to practice and enhance language abilities, receptive skills and productive skills, vocabulary is the most crucial thing to learn and comprehend.  \nNowadays, good English skills are needed for many purposes, especially for students. Students need to have a good command of English, whether it is for their studies, graduation requirements, job qualifications, or to get scholarships abroad. In achieving these goals, many students learn English independently using technology. According to Apoko et al. (2023), learning English as a foreign language (EFL) is getting easier and more useful by using technology in this digital era, which can be accessed anytime and anywhere. In achieving the goal of mastering a foreign language, students learn independently to improve their vocabulary acquisition. In recent years, many apps that assist learning have been developed to improve learners'English language skills.  \nThere is one smartphone app that is thought to assist EFL students in improving their vocabulary in particular and their English in general. Duolingo is the name of the app. Duolingo app is an online language learning platform that can be accessed worldwide. This application support support independent learning, with can be accessed anytime and anywhere through mobile devices or computers. It allows users to learn according to their own schedule without being bound by a specific time or place. The well-known language-learning app Duolingo exemplifies the integration of technology in language learning. The program focuses mostly on translation,  \ndictation, and pronunciation. Gamification techniques are used to engage and motivate students (Munday, 2016) . The app uses the voice of a native English speaker in its operation, which means it can provide an advantage to English learners and to practice English language skills especially in mastering English vocabulary. The app also uses a combination of text, audio and visual exercises to help learners develop their language skills (Tiara et al., 2021) . The app also incorporates gamification elements, such as leveling up, earning virtual money and competing with friends, to increase motivation and engagement. The app is ","cbCainUBglMczTNe","https://ap.wps.com/l/cbCainUBglMczTNe","pdf",27268,"English","# CHAPTER I - INTRODUCTION\n## 1.1 Research Background","[{\"question\":\"Why is vocabulary considered an important aspect of learning a language?\",\"answer\":\"Vocabulary is described as a language foundation that helps learners express thoughts and feelings, provide information, share ideas, and understand others through communication.\"},{\"question\":\"What problems can occur when learners have inadequate vocabulary?\",\"answer\":\"Learners may struggle to explain complex concepts or provide detailed descriptions, which can lead to misunderstandings and reduced effectiveness in communication.\"},{\"question\":\"How does the document describe Duolingo’s role in vocabulary learning?\",\"answer\":\"Duolingo is presented as an online, mobile-accessible platform that uses gamification and varied exercises (text, audio, visual) to help learners practice English vocabulary and develop overall language skills.\"}]","CHAPTER I - INTRODUCTION - Research Background | PDF",1790606711,23]
