The Effects of Vocabulary Self-Collection Technique Toward Students’ Vocabulary Mastery At The Eighth Grade of SMP 1 Lasusua

Abstract

This study was aimed to find out the effect of vocabulary self- collection strategy technique toward students vocabulary mastery. A further concern of this study was to investigate the significant difference of vocabulary mastery between two groups who were taught by using vocabulary self-collection strategy. The research design of this study was a quasi experimental research. The population  was  the  eighth  grade  students  of  SMP  Negeri 1 Lasusua  in  the academic year of 2018/2019. The samples consisted of 66 students. The data were obtained by giving vocabulary test to the VIII A as experimental group and VIII C as control group. The study was started by giving pre-test, treatments and post-test to both groups. Vocabulary self-collection strategy was used as treatment in the experimental group. The results of the test were analyzed by using t-test formula to know the difference of the students’ achievement in vocabulary mastery between two groups.  In the pre-test result, the mean score of experimental group was 65 and the control group was 65,16. However, the result of post-test was increased. The analysis of the test result showed that the students` improvement of experimental group was higher than control group. In the post-test, the mean score of the experimental group was 77,50 while the control group got 70,78. The result of the t-test of mean difference was 3,549 and t-table was 1,997. It means that t-value was higher than t-table (3,549 >1,997). The computation showed that the alternative hypothesis (Ha) stating that “there is a significant difference in vocabulary mastery between the students who are taught by using vocabulary self- collection strategy. While, the null hypothesis (H0) stating that there is no significant difference in vocabulary mastery between the students’ who are taught by using vocabulary self-collection. Based on the hypotheses the conclusion that vocabulary self-collection strategy is more effective to be implemented in teaching vocabulary to improve students` vocabulary mastery.
