The findings reveal a significant improvement in students' performance, where the percentage of students who met the minimum score criteria increased from 41.17% in Cycle I to 82.35% in Cycle II. Based on the results, it can be concluded that the Whole Brain Teaching method effectively improves vocabulary mastery. The key teaching steps applied included Class-Yes, Five Classroom Rules, Teach-Okay, Scoreboard, Hands and Eyes, Switch, and Mirror.
