The study used a quantitative approach with a one-group pretest–posttest pre-experimental design. The subjects were 20 students of the Actuarial Science Study Program at Darunnajah University. The research instruments were an analytical skills test and a project assessment rubric. Data were analyzed using descriptive statistics, the Shapiro–Wilk normality test, hypothesis testing using paired sample t-test, and N-Gain analysis assisted by R software. The results showed a significant increase in students' analytical skills after the implementation of PjBL assisted by R software (t = 159.32; p < 0.001) with an average N-Gain value of 0.577 in the moderate category. The increase in analytical skills was also reflected in the students' process of analyzing iterations, interpreting numerical results, and evaluating Newton Raphson method solutions through computational-based projects. Thus, Project Based Learning assisted by R software is effective in improving students' analytical skills in learning the Newton Raphson method.</p>2026-02-11T11:43:06+07:00Copyright (c) 2025 Mortalita: Journal of Mathematics and Its Applications
