Abstract: This study assessed the mastery of graphing linear equations among Grade 8 students using PhET simulations to address numeracy challenges. Students from a public high school in Nueva Vizcaya, Philippines, participated in the study. The control and experimental groups were assigned to two different sections. Employing a quasi-experimental pretest-posttest control group design, descriptive statistics (including frequencies, percentages, means, and standard deviations) were used to measure the students’ mastery levels. A paired-sample t-test was used to compare pretest and posttest results within each group, while an independent-sample t-test assessed significant differences in gain scores between groups. Results showed improved mastery of graphing linear equations after the interventions, with both groups exhibiting higher posttest mastery levels than pretest levels. Additionally, the experimental group displayed greater improvement. Hence, PhET simulations were found to enhance the learning of graphing linear equations and are recommended for continued use.
