instrument. She used Montessori method which is taught in experimental class
,while in control class she used conventional method. In technique of analyzing
data, mean and standard deviation are used in the descriptive analysis, while test
of normality, homogeneity and t test are used in the inferential analysis. To see
whether the hypothesis is accepted or rejected, the result of t-test is consulted to
the t-table at the 0.05 significance level.
The result of the thesis shows that the mean of pre-test is 64.84 and the
mean of post-test is 75.47. it indicates that there is on improvement of students
vocabulary mastery after the researcher used Montessori method.
From the computation , the value of t-test is higher than t-table with the
level of significance 5% and N= 32 (4.162> 2.000). It means Ho is rejected
whereas Ha is accepted. Based on the result findings, it can be concluded that
