Subclaims¶

q2 i? The report asserts, citing recent research syntheses, that the brain develops most fully when children feel safe, connected, supported, engaged, and challenged, with rich opportunities to learn. → Darling-Hammond 2025 q2 i? The report asserts that variability in human development is the norm, with multiple pathways and no one best pathway to effective learning, so standardized pacing misses most children's needs. → Darling-Hammond 2025 q2 i? The report asserts that supportive, responsive relationships with caring adults are essential for children's healthy development and can buffer the negative effects of adversity. → Darling-Hammond 2025

Evidence¶

Darling-Hammond 2025¶

Darling-Hammond, L., Hyler, M. E., & Wojcikiewicz, S. (with Rushing, J.). (2025). Design principles for teacher preparation: Enacting the science of learning and development. Learning Policy Institute. https://doi.org/10.54300/115.854

q2 · i? · review · r1

This is the report's own synthesis section ('What the Science Says' framing in the introduction), a narrative review attributing these understandings to recent syntheses published in Applied Developmental Science. The article states the brain "grows and changes throughout life in response to experiences and relationships". No effect sizes are printed; these are the report's framing assertions.

"The brain grows and changes throughout life in response to experiences and relationships. The nature of these experiences and relationships matters greatly for development. The brain develops most fully when children and youth feel emotionally and physically safe"

Discussion¶

Related Claims¶

• Adverse childhood experiences create toxic stress that impairs attention, learning, and behavior, and school responses can magnify or buffer the harm — related
• Nature and nurture interact dynamically: children's experiences shape their biology as much as biology shapes development — possibly the same claim (merge candidate)
• Principals' strongest impact on student learning comes through building a positive, measurable, and malleable school climate — related
• Experiences and environments in a baby's first three years significantly shape brain structure and functioning — related
• Positive developmental relationships are the active ingredient in effective child-serving systems, buffering stress and fueling learning — a narrower finding that bears on this claim
• Cognitive, emotional, and social skills should be taught alongside content because learning is integrated in the brain — related
• Co-regulation strategies were reported to create a safe, positive classroom climate and to help youth manage emotions — related
• Anxiety and toxic stress from stereotypes, bullying, and exclusionary practices impede learning by preoccupying the brain with worry and fear — related
