The researchers have identified common problems in the learning process. The difficulty of understanding vocabulary in writing subject. This is due to the lack of opportunities for them to practice using English vocabulary with their classmates, both inside and outside the classroom. As a result their vocabulary mastery is still underdeveloped, such as improper pronunciation, low vocabulary mastery, low level of motivation, and low grammar mastery. This type of research uses experimental quantitative research population refers to a specific group of objects or subjects that share certain qualities and characteristics defined by the researcher for the purpose of study and the drawing of conclusions. Data collection was carried out through testing, followed by a t-test to analyze the results. The analysis showed that the experimental group achieved an average post-test score of 83,63636, while the control group scored an average of 59,09091. The two-sample t-test under the assumption of equal variances yielded a calculated t-value of 7.961866, notably exceeding the critical threshold of 0.249. Based on the decision criteria, this result leads to the rejection of the null hypothesis (H₀) in favor of the alternative hypothesis (Hₐ). Since the calculated t-value (7.961) is higher than the critical value from the t-distribution table (2.085963), this suggests a statistically significant difference between the groups. Thus, Netflix affects the mastering vocabulary of 7.961866 while the other factor of 0.92039 is influenced by other aspects that are not studied in this study. These findings suggest that Netflix has a significant positive impact on improving vocabulary mastery among second-semester English education students.
