Speaking skills are considered one of the most important language skills. For this reason, a learning model is needed that is appropriate to the subject and students to improve speaking skills. This research aims to determine the effectiveness of the Quiz-Quiz Trade cooperative learning model in learning speaking skills if vocabulary mastery is controlled. This research used the True Experiment Design method and was carried out at Nahdlatul Ulama Mranggen Demak high school with a sample of 58 students grouped into two classes. Data collection techniques in this research used observation and tests, which were then analyzed using descriptive analysis techniques, ANAVA techniques, and ANAKOVA techniques. From the analyzed data, the results showed that speaking skills in the experimental class were higher than in the control class. The use of this model was carried out well with increasing observation results. Besides that, the results of the ANAVA analysis for speaking skills showed an insignificant value, namely F = 1.452 and F criterion = 4.013. The results of the ANAVA analysis of vocabulary ability show significant results because the F value is greater than the F criteria, namely 6.292 and 4.013. Besides that, the results of the covariance analysis of speaking skills after controlling mufrodat mastery showed significant results with F = 7.684 and standard F = 4.016. These results indicate that the research hypothesis can be accepted because it is supported empirically.
