Equitable learning recovery must be grounded in solid research
The COVID-19 pandemic, coupled with political and social unrest, has deeply disrupted the lives and learning experiences of most students. It has created an urgent need to address long-standing opportunity gaps and has highlighted the importance of providing resources that support student achievement, social-emotional learning, and physical and mental well-being. This urgency for action to address the impacts is valid, but it has also created a noisy environment of potential options of what might be best for students. It’s critical, now more than ever, for decisions to be grounded in solid research.
