Conducted with 11th-grade students at SMA Global Madani in Bandar Lampung, the research used mixed research and employed random sampling to select two classes with similar English proficiency levels: one experimental class and one control class. Quantitative data were gathered using pre- and post-tests to measure vocabulary mastery, while qualitative data were collected through open-ended questionnaires to capture students' perceptions. The results showed a significant improvement in vocabulary mastery for the experimental group, with verbs showing the highest gains. Students perceived the integrated strategy as easy, relaxing, interesting, motivating, confidence-boosting, and beneficial to their learning outcomes. These findings suggest that VSS integrated with PC not only enhances vocabulary mastery but also creates a positive and supportive learning environment. It highlights the potential of integrating VSS with PC as an effective strategy for teaching vocabulary that supports both language improvement and student motivation.
