The Locker Room Moment
Taking off my boots at the end of the day, I listened to the usual locker-room chatter.
Instructors were celebrating — proud of helping their students ski new terrain, bragging about runs through chutes and trees.
Then a voice from around the corner said:
“No matter what I said today, this kid just couldn’t get his skis parallel. I used jumps, shuffles, hockey stops — nothing worked. I guess some people just don’t get it.”
I froze.
I’d been there. The frustration when progress is slow, when our go-to drills don’t connect, when a student just doesn’t get it.
When Teaching Feels Stuck
We show students what to do — how much to bend their knees, how to face their torso, how to hold their hands.
We tell them what they should feel — pressure on the outside ski, weight through the boots.
We explain the benefits of good form.
And when it still doesn’t work, that quiet frustration builds. Behind the calm exterior, you want to snap a pole in half.
That night, alarm bells went off in my head. Why are we blaming the student? Isn’t it our job to adapt our teaching and the learning environment to meet their needs?
“They don’t know what they don’t know,” I thought. “But I’m a professional — I should know how to help them learn.”
That was the start of a long, humbling journey.
A Hard Truth: Maybe We’re Not as Good at Teaching as We Think
What if our teaching approach isn’t as effective as we believe?
What if all the talking, explaining, and demonstrating might be getting in the way of true learning?
It takes courage to admit that our way might not be the best way. But that realization opened the door to something better.
From “Instructor” to “Learning Facilitator”
My first change was in language.
I stopped thinking of myself as an Instructor and started seeing myself as a Learning Facilitator.
My role wasn’t to command movement — it was to design experiences that let learning emerge.
That shift led me deep into the science of how humans acquire and adapt motor skills — how we actually learn to move.
That’s where I discovered Ecological Dynamics, and realized the traditional model I’d been using — Information Processing — was limited.
The Limits of Information Processing
Most ski instruction follows a simple logic:
The instructor tells the student what to do.
The student thinks about it, forms a mental picture.
The student tries to copy it.
It’s neat, it’s structured, and it makes sense.
But it doesn’t work for everyone. Thinking about movement doesn’t create skilled movement.
Over years of teaching, I saw this approach succeed occasionally — but fail far too often.
Discovering Ecological Dynamics
The Ecological Approach, grounded in the science of Ecological Dynamics (see perceptionaction.com), turned my world upside down.
It proposes that learning doesn’t happen inside the head alone — it happens through interaction between the person, the task, and the environment.
Two key insights changed everything:
We learn movement by doing, not by talking about it.
Muscle memory and coordination emerge from experience, not explanation.There’s more than one correct way to reach the same goal.
Watch any World Cup race: the best skiers share core principles — balance, outside-ski alignment, independent leg steering — but no two move exactly alike.
Every body is different. Every solution is unique.
The Constraints Led Approach: Turning Theory Into Practice
The Constraints Led Approach (CLA) is how we apply Ecological Dynamics in real life.
Instead of prescribing movement, we design learning environments that guide self-discovery.
We manipulate constraints on:
The Task – e.g., ski with one pole, limit turns to a narrow corridor.
The Environment – e.g., vary slope pitch, snow texture, visibility.
The Equipment – e.g., shorter skis, no poles, different boots.
These boundaries shape exploration. The student naturally finds a movement solution that works for their body and their perception of the environment.
“We don’t tell them what to do with their body — we set the stage for their body to figure it out.”
Why It Works
The CLA respects individuality. Each learner brings their own history, strengths, and perceptions.
By designing effective constraints, we allow their body to self-organize toward efficient, adaptable movement.
Instead of copying, they create.
Instead of thinking about skiing, they become skiers.
And when movement emerges from within — it sticks. It feels natural, effortless, and alive.
A Call to Coaches and Instructors
If you’ve ever felt the frustration of a stuck student, you’re not alone.
But don’t blame the learner — rethink the method.
Move from explaining to designing.
From instructing to facilitating.
From telling to creating environments that teach.
The Constraints Led Approach won’t just change how your students learn — it will change how you see teaching itself.
Because at the heart of it all:
Our job isn’t to control learning. Our job is to create the conditions for it.
