Abstract
This study aimed to analyze the relationship between the implementation of the Jigsaw cooperative learning model and students' mathematical problem-solving ability in quadratic functions among tenth-grade students at SMK 2 Trisakti Pematang Siantar. The study employed a quantitative approach with a pre-experimental one-shot case study design. The sample consisted of 30 students from class X TKJ, selected through a class lottery. Data were collected using a 15-item questionnaire and a posttest comprising five essay questions. Data analysis included descriptive statistics, the Shapiro–Wilk normality test, simple linear regression, a t-test, and the coefficient of determination. The results showed a mean questionnaire score of 85.53 and a mean posttest score of 78.20. Regression analysis yielded the equation Y = 60.338 + 0.209X, with a t-value of 0.876 and a significance level of 0.388 > 0.05. The coefficient of determination (R²) was 0.027, indicating that the regression model explained 2.7% of the variance in students' mathematical problem-solving ability. The study concluded that the implementation score of the Jigsaw cooperative learning model had a positive but statistically insignificant relationship with students' mathematical problem-solving ability.
