The objective of the research is to see the effectiveness of Games and Simulation in speaking skill on the seventh grade students at SMP Teknologi Pilar Bangsa. The technique applied in this research was quas-experimental research. In this research, there were two classes taught by using different techniques. The experimental class was taught by using Games and Simulation technique while the controlled class was taught by using conventional technique. Futhermore, this research was conducted through the following procedures: giving pre-test, applying treatments, and giving posttest. The sample of this research were 30 students of class 7.1 and 31 students of class 7.3. Normality test was tested by using chi-square. From the calculation of normality showed that the data are normally distributed population. The homogeneity test result of students learning reading comprehension has homogeneous variance. Furthermore, the t-test showed that t-count of experimental class is 3.25, was higher than t-table. The t-test of control class is 3.25, was higher than t-table. It means that finding of this study shows that there is a significance difference in the result between students in class 7 as control class that were taught without games and simulation technique and students in class as experimental class that were taught speaking skill using games and simulation technique.
