Cofounder of Conexiones: Plataforma de las Ciencias del Aprendizaje and Instructor at Harvard University. The United States of America and Ecuador.

Dr. Tracey N. Tokuhama-Espinosa is an educator, researcher, and thought leader working at the intersection of neuroscience, psychology, and education. She serves as an instructor at the Harvard University Extension and Summer Schools (Faculty of Arts and Sciences) and is the Director of Education at Connections: The Learning Sciences Platform. She lives and works between Boston, USA and Quito, Ecuador.

Tracey Tokuhama-Espinosa has dedicated her career to understanding a simple but profound question: why do some people thrive in learning environments while others struggle? Her work explores human variability in learning, emphasizing that there is no “one-size-fits-all” approach to education.

Since 2012, she has taught a widely recognized course at Harvard on the neuroscience of learning, bringing together insights from brain science, psychology, mental health, and education. At the heart of her teaching is a guiding question she poses to her students: “What do you want to know and why?” This question reflects her belief that meaningful learning begins with curiosity and purpose.

Beyond academia, she finds inspiration in everyday growth—whether in her students or in her garden—where she enjoys watching things develop over time.

Description of her work

Tracey’s work bridges research and practice, making complex ideas about the brain accessible and useful for educators around the world. Her current projects include:

• Writing new books on mental frameworks and on mind, brain, and education, aimed at helping educators better understand how students think and learn.
• Developing a free, open-source teacher training platform in both Spanish and English, grounded in her approach called “radical neuroconstructivism,” which emphasizes how learners actively build knowledge.
• Designing educational programs that integrate insights from neuroscience, health, and wellbeing into classroom practice.
• Exploring cultural neuroscience to better understand which aspects of learning are universal and which are shaped by culture.

Her work is especially impactful because it connects scientific research directly to classroom strategies teachers can use every day.

Key findings

Over the years, Tracey Tokuhama-Espinosa has introduced several influential ideas and resources in the learning sciences:

• She coined the term “holonic thinking*,” which encourages seeing learning as interconnected systems rather than isolated parts.
• She identified five foundational building blocks of early learning—symbols, patterns, order, categories, and relationships—which support skills in math and language.
• She developed the concept of “radical neuroconstructivism,” highlighting that learners actively construct knowledge through experience and interaction.
• Through a global study across 21 countries, she collected over 400 questions children have about their own brains—revealing important gaps in how we teach neuroscience and self-understanding.
• In her work on writing and the brain, she has shown that writing is not just a skill but a complex thinking process, often invisible to educators, that unfolds in stages. For example, when a student struggles with writing, the challenge may not be grammar or vocabulary—it may be difficulty organizing ideas or making connections. Understanding these hidden stages helps teachers provide more targeted support.
