This study aimed to enhance the mathematical performance of the learners through the use of localized module in grade 9 ? Algebra, an intervention material in Mathematics 9 of Perez National High School, Perez, Quezon. One ? group experimental design was used in this study to determine the effectiveness of the localized module in remediating the least ? mastered competencies of the grade 9 learners. The descriptive design of research was also used to determine the level of acceptability of the localized module. The developed localized module is highly acceptable in terms of content, applicability, clarity and accuracy. Moreover, improvement in the performance of the learners in terms of pre ? test and post -test was evident after the utilization of the localized module. Lastly, this study also concluded that there is significant difference between the performance of the learners before and after using the localized module since the difference was found significant and null hypothesis was rejected. Thus, the used of the localized module was effective in enhancing the performance of the learners. This study recommends that teachers must maximize their potential in making more effective material by localizing module. Administrators must include the making of the development of localized learning modules in seminars and trainings for teachers. Learners can learn more effectively with the use of localized module for they can use it at their own pace. Lastly, for future researchers, they may use and improve the developed localized module and apply it in different locale and subjects to help improve learning.
