variety of vocabulary. With insufficient vocabulary, it is difficult for students to 
communicate with their English skills to others, express their ideas or opinions, 
understand or comprehend simple texts, and listen to the instructions of the 
materials that they learned. Learning vocabulary is not easy, especially to 
Indonesian students, where English is considered as a foreign language, because it
consists of several aspects that every student must know and master, such as 
acquiring a lot of words, arranging correct sentence patterns and others.

memorizing new words, the lack of interest and motivation in learning English.

materials, or methods used in English learning process.
