“Learning vocabulary through games the effectiveness of learning vocabulary through games” (Huyen & Nga, 2003), the purpose was to explore how and whether the game could help learners learn vocabulary effectively. The researchers began applying games in their classes, observing others teachers’ class and interviewing teachers and learners for their reactions and attitudes. The instruments were the post-game surveys and the interview surveys. The findings were revealed in 3 groups, which are learners’ attitudes, learners’ progress and unanticipated problems. Learners’ attitudes were in the same way that games could help them a lot in vocabulary learning. Learners could obtain more words and applied them within relaxed and comfortable environment such as games.
Unclear instruction, lack of cooperation of learners and using L1 while playing games were the problems, which were always found while playing games in classes. These problems could cause unsuccessful learning languages unless they were managed in an appropriate way.
