How many educators have read a book, attended a conference, or pursued college or graduate work in how the brain learns? When the editors of Research-Informed Teaching asked their colleagues, they found that only 20% had. That discovery led to a strategic decision by their school-they would train 100% of their current and future teachers and administrators in the science of teaching learning, using the promising principles, research, and strategies in mind, brain, and education (MBE). The editors started collecting cases of MBE in action, resulting in this compilation of research-informed stories that will engage the reader in the transformative work of using research to inform their practice in a way befitting what it means to be an evidence-informed educator. Every child, every day, everywhere deserves teachers and school leaders who know how the brain learns. This collection provides models of how to make that possible in your classroom, school, district, or program with your students.
