This study aimed to determine the effect of flipped blended learning on the performance of Grade 10 students in Mathematics. Utilizing a quasi-experimental design, 40 students were divided into experimental (flipped blended learning) and control (modular learning) groups. Pretest and posttest scores, gain scores, and Quarter 1 grades were analyzed. Results indicated that while the control group had higher pretest and posttest scores, the experimental group showed a slightly greater improvement in gain scores. Significant differences were noted in the groups’ posttest scores and first quarter grades but no statistically significant difference was observed in the groups’ gain scores. The study concluded that both flipped blended learning and modular distance learning have comparable effects on the mathematics performance of the control und experimental groups.enThesis
