This document is an action research proposal from Liwliwa B. Suguitan, a Teacher I at Salpad Integrated School, to improve students' mastery of mathematics through localized game-based activities. The proposal outlines an action research plan to develop and implement localized game-based learning activities to help increase 7th grade students' mathematics test scores. It includes sections on the context and rationale, research questions, proposed innovation and strategy, research methods for data collection and analysis, a workplan and timeline, cost estimates, and plans for disseminating and utilizing the results. The goal is to determine if game-based learning can help improve students' level of mastery in mathematics.
