The subjects of this study were 15 students, consisting of 3 males and 12 females. The initial observation was conducted in March 2026, and the research action was carried out in April 2026. The research method used was Classroom Action Research (CAR) with a spiral model design consisting of two cycles. Data collection techniques included tests, observation, and documentation.
