A thesis, State Islamic Institute of Bukittinggi, 2018. This research was due to several problems found in the field that are; the students were lack of vocabulary, most of students had bad English pronunciation and teacher still used conventional strategy in teaching vocabulary. In teaching vocabulary mastery, there are strategies that give effect to the students’ vocabulary mastery and one of the strategies is Super Word Web strategy. This research aims to improve students’ vocabulary mastery by using Super Word Web Strategy. This research was an experimental research by using quantitative approach. The total population was 68 students from class VII A and class VII B. Class VII A was used as experimental class in which the treatment was given, while class VII B was used as control class where the researcher only used the conventional strategy in teaching vocabulary. The researcher used Purposive Sampling Technique in chossing the sample. To analyzing the data, the researcher used Liliefors test to test the normality and F-test to test homogeneity. Then, to test the hypothesis the reasearcher used t-test and (α) = 0.05. Based on the calculation of pre-test and pos-test from experimental class, it was found that the t-obtained (10.75) was higher than the t-table (1.960) with the degree of freedom (df) = 66 and level of significance (α)= 0.05/2= 0.025. So that, the alternative hypothesis (Ha) was accepted which means that there is significant effect of Super Word Wev strategy on students’ vocabulary mastery. Then, the calculation of post-test both classes is as follows, it was obtained that the t-obtained (7.83) which was higher than the t-table (1.960) with the degree of freedom (df) = 66 and level of significance (α) = 0.05/2= 0.025. So that, the alternative hypothesis (Ha) was accepted which means that there is significant difference between using Super Word Web strategy and using conventional strategy. Then, the t-obtained in post-test both classes was t-obtained (7.83) which was higher than t-table (1.645) with degree of freedom (df) = 66 and level of significance (α) = 0.05. So that, the alternative hypothesis (Ha) was accepted which means that the students who are taught by using Super Word Web strategy is better than the students who are taught by using conventional strategy. So, it can be conclude that the entire hypotheses are accepted. There for, it is proved that using Super Word Web strategy can help the student at seventh grade of SMPN 2 Payakumbuh in improving their vocabulary mastery.
