Potential when children own their learning journey
Overview
Six Research Pillars
What the evidence
actually says
Learner-Driven Environments
Students in self-directed schools show higher achievement gains, better college persistence, and stronger intrinsic motivation.
Experiential Learning
Learning by doing produces deeper retention than passive instruction — confirmed across science, history, and literacy.
The 4 C's
Critical thinking, communication, collaboration, and creativity are the skills that actually predict life and career success.
Tech-Free & Tech-Light Studios
Jonathan Haidt's research shows the phone-based childhood is causing an epidemic of anxiety and depression. Spark is fully tech-free. Growth is tech-light.
Mastery-Based Learning
When information flows freely — without fear of failure or grades — students reach higher levels of cognition.
Multi-Age Studios
Mixed-age groups accelerate social-emotional growth, build mentorship skills, and mirror how the real world works.
01
Learner-Driven Environment
Children learn best when they're in charge
Students in study schools exhibited greater gains in achievement, had higher graduation rates, were better prepared for college, and showed greater persistence once there.— Linda Darling-Hammond, Stanford
02
Experiential Learning
Doing beats listening,
every time
"No research has ever found a benefit to assigning homework (of any kind or in any amount) in elementary school."
— Alfie Kohn, Unconditional Parenting

The 4 C's of Education
Skills that actually matter in the 21st century
Sitting in rows and listening to content delivered through lecture is slowly being replaced with active learning environments that develop the skills employers actually need.— National Education Association
04
Tech-Free & Tech-Light Learning
Spark Studio · Ages 4.5–7
Fully Tech-Free
No screens, no devices. These are the years when imagination, language, sensory play, and face-to-face connection lay the foundation for everything that follows.
Growth Studio · Ages 7–10
Intentionally Tech-Light
Technology is introduced purposefully and sparingly — as a tool, not a crutch. Real-world projects, hands-on materials, and human interaction remain the core.

Countering an 'Anxious Generation': more autonomy and fewer screens
Jonathan Haidt · NPR Health, 2024
We've had a play-based childhood for 200 million years — that's how mammals wire up their brains. Somewhere in the 1990s it stopped, and was replaced very suddenly by the phone-based childhood. Kids who went through puberty on a smartphone with social media are at much, much higher risk of being anxious and depressed.— Jonathan Haidt, NYU Stern
Over the past two decades, the cognitive development of children across much of the developed world has stalled and, in many domains, reversed. Literacy, numeracy, attention, and higher-order reasoning have declined — despite increased school attendance and expanded public investment.— Dr. Jared Cooney Horvath, U.S. Senate Testimony
Haidt's four norms for restoring childhood: no smartphones before high school, no social media before 16, phone-free schools, and far more independence and free play in the real world.
At Acton, we start building that foundation from day one.

When students are engaged and motivated, information flows freely through the prefrontal cortex, and they achieve higher levels of cognition, analysis, and creative problem solving.

Bodies that move are minds that learn
Kids who get extra physical activity in school do better in reading and math — and the benefit shows up consistently across demographics and grade levels.— CNN Health
