Crosswords Puzzle Games: Increasing Students’ Vocabulary Competence at Faculty of Computer Science

English is a Foreign Language as a subject that has been studying since elementary. However, most of the students; English is a difficult course to learn. Thus, it needs improvement both from the media system used and the appropriate strategy for the English course as a general basic course in particular in the Faculty of Computer Science into a fun learning. A way to make English fun and easy to learn is the use of the strategy of a game called Crossword Puzzle Games. The purpose of the research is to find out whether the use of Crossword Puzzle strategy can improve the value of English courses, whether by using the Crossword Puzzle Learning Strategy can improve students' Vocabulary and find out whether using the learning strategy of Crosswords Puzzle can increase students' interest in Computer science faculty in learning English.
