Educational research informs policy changes by providing evidence-based insights into effective teaching methodologies and learning outcomes. It identifies the strengths and weaknesses of existing practices, guiding educators and policymakers to make informed decisions about curriculum development and resource allocation. Research can also highlight the needs of diverse student populations, leading to more inclusive policies that address equity and accessibility issues. By analyzing trends and outcomes from various educational settings, stakeholders can implement strategies that improve educational quality and effectiveness, ultimately resulting in better student achievement.
