This study investigated the effects of employing games on students’ speaking performances in the classroom. 74 non-English major students, 36 students from the Tourism and Travel Management and 38 from the Office Management major from Tra Vinh University, participated in the study. The control group was trained with the methods of P-P-P (presentation, practice, and production) while the experimental group was trained with the same process but using selective games in the learning processes. Data collection was from the pre- vs. post-tests, questionnaire and interviews for analysis. The findings revealed that using games in the speaking classrooms, the students were motivated in the learning process and their speaking skills improve remarkably. The current study suggested teachers in the research context to apply gaming activities as an effective method to improve students’ participation in the learning processes.
