Data analysis resulted that t-observed value was higher than t-table value (>2.000) at level of significance 0.05 with the degree of freedom (df) 35. Since t-observed value was higher than t-table value, it means Ha was accepted and Ho was rejected.

It is recommended for English teachers to apply the Duolingo as a medium method to assist students' vocabulary mastery.
