Based on the results of the analysis was conducted using the Paired sample test, the sig (2-tailed) value is smaller than 0.05 (0.001 <0.05), so (Ha1) is accepted and (H01) is rejected. This means that there is a significant effect was found students' writing ability after using the padlet application media, and the results of the independent sample t-test show that the sig value (2-tailed) is lower than 0.05 (0.001 <0.05). And the t-test value is higher than the t-table value (-6.600 < 2.000) with degrees of freedom (df) = 59, then (Ha2) is accepted and (H02) is rejected. This shows that there is a significant difference was found between students who were taught using the padlet application as a learning media for writing descriptive text and students who do not use the padlet application.
