Abstract
This study determined whether the implementation of project ADFEISM can enhance grade 9 students’ performance in learning quadratic equations. This study used a quasi-experimental design with two intact classes of problematic sections. Both groups underwent the pretest before the lessons on quadratic equations were introduced. The controlled group was exposed to the conventional teaching method, while the experimental was exposed to teaching with the project ADFEISM with the mastery learning approach. Based on the findings, it is proved that there is a significant difference between the performance of the students in the control and experimental group towards learning quadratic equation. This implies that teaching of Mathematics with a special emphasis of the basic topics like what were included in the Project ADFEISM will help students enhance their mathematics performance and make them more prepared to study advanced mathematical concepts.
