Lenses, not religions
Theories
What you believe about how children grow changes the session you write tomorrow. These are the development and PE theories under this path — and what they do to a body.
Where to look
Want the people, not only the lenses? Open pioneers.
Maturational theory
The nervous system unfolds on a biological timetable. Skills appear when the child is 'ready,' not when we drill them.
On the floor. Do not force a skip on a three-year-old who is still organizing a run. Offer the next step they can almost do, then wait while they repeat it in play.
On development. Protects children from shame and from being asked for a body they do not have yet. Development looks calmer, and late bloomers are not treated as problems.
Watch. If you only wait, children who never see a ball, a beam, or a hill look 'delayed' when they were only underserved. Opportunity is part of the timetable.
Week 2Dynamical systems
Movement is not stored as a program. It emerges from the child, the task, and the room, in the moment.
On the floor. Change one constraint: a bigger ball, a quieter wall, a tape path, a seated start. Watch three attempts before you talk.
On development. Development becomes plastic. The same child 'can't catch' in a loud gym and can catch on the floor with a scarf. You stop blaming the body for the environment.
Watch. Do not throw out teaching. Constraints invite a pattern; children still need a cue, a model, and a reason to stay.
Week 3Phases of motor development
Reflexive, rudimentary, fundamental, then specialized. Sand has to pass through the neck of the glass. You cannot pour sport into an empty fundamental chamber.
On the floor. Name the phase you are actually in. Toddlers: rudimentary and early locomotor. Preschool and early school: fundamental skill themes. Specialize only when the letters are there.
On development. Children build a movement vocabulary before they are asked to write sport sentences. Fewer gaps at seven. More joy at nine.
Watch. The hourglass is a map, not a verdict. Children sit in two phases at once — a mature run and a baby throw is typical, not broken.
Week 2Proficiency barrier
If fundamental skills never become reliable, later sport and play stay closed. The child is not lazy. They hit a developmental wall.
On the floor. Protect FMS time. A year of tag is not a throwing curriculum. Use the Skill library and the session planner so every child gets letters, not just games.
On development. Children who own a land, a throw, a skip, and a stop can enter games without shame. The ones who don't quietly leave PE, recess, and the playground.
Watch. The barrier is not a moral line. Opportunity, disability, and fear all change how high it sits. Adapt the task; do not write the child off.
Week 4Skill themes approach
Curriculum is organized by families of movement — stability, locomotor, manipulative — not by sports. Movement concepts (space, effort, relationships) are the adverbs.
On the floor. Write the session as 'today we jump, in different directions, like a cat.' One theme, one concept, one cue. Dress it in a story so they will repeat it.
On development. Development fills in across the whole alphabet instead of over-training one sport. A child who can balance, travel, and send is ready for anything the culture offers next.
Watch. Themes without play become drills. Play without themes becomes a year of dodgeball with gaps.
Week 4Constraints-led teaching
You do not have to narrate every joint. Change the individual, the task, or the environment and let a better pattern self-organize.
On the floor. Open the Constraints lab. Pick throwing or landing. Change one thing. Count three attempts. Do not lecture the elbows.
On development. Learners become searchers, not copy-machines. Development is more adaptable — the skill survives a new ball, a new floor, a new game.
Watch. Hands-off is not the same as mind-off. If the child is lost, they are still in the cognitive stage: demo, one cue, then a constraint.
Week 3Three stages of learning
Cognitive: figuring out what to do. Associative: refining. Autonomous: automatic enough to notice the game.
On the floor. Match the dose to the stage. Beginner: demo, simplify, encourage. Intermediate: vary and give specific feedback. Advanced: problems, not lectures — let them coach a peer.
On development. The right stage grows the skill. The wrong stage stalls it — you either flood a beginner with corrections or bore an advanced child with 'step with the other foot' forever.
Watch. Stage is per skill, not per child. A seven-year-old can be autonomous at running and cognitive at skipping.
Week 3Teaching Games for Understanding
Start from a simplified game and a tactical question — 'how do we make it harder for them to get the ball?' — then teach the skill the game just asked for.
On the floor. Small-sided, one rule, one question. Freeze, ask, try the skill, back into the game. The skill has to survive play, not a line drill.
On development. Children develop game sense and decision-making, not only form. They know why the skill exists, so they keep it when the drill ends.
Watch. A game with no skill teaching is just recess. Use TGfU after the letters exist, or teach the letter inside a tiny game — not a full-sided match.
Week 7Self-determination theory
People stay when three needs are fed: autonomy (I have a say), competence (I can do this), relatedness (I belong here).
On the floor. Offer a real choice (this station or that). Set the task so success is likely, then edge it. Say every name. Let a child sit out without losing the relationship.
On development. Development continues after you leave. Controlled children comply and quit. Children who feel choice, skill, and belonging keep moving for life — that is the actual developmental outcome.
Watch. Fake choices ('you may do the drill or the drill') are control in a costume. One real fork in the session is enough.
Week 6Mastery climate (TARGET)
Task, Authority, Recognition, Grouping, Evaluation, Time. A mastery room says 'your next step.' An ego room says 'who won.'
On the floor. Praise the attempt and the strategy, not the ranking. Mix groups. Evaluate against yesterday's self. Give enough time that rushing is not the skill.
On development. In a mastery climate, the cautious child and the already-good child both develop. In an ego climate, only the already-good stay, and even they get brittle.
Watch. Competition is not the enemy. Unchecked public ranking is. A race can be 'beat your last time,' not 'beat her.'
Week 6Play as biological necessity
Play is how brains wire, bodies rehearse, and people attach. The opposite of play is not work. It is depression.
On the floor. Put the skill inside a story or a small-sided game. Stop while they still want one more. If it is not playful, it will not be repeated enough to develop.
On development. Skill without play is a trick that fades. Play without any skill is a party. Together they are the repetition engine of motor development — and of confidence.
Watch. Do not use 'play' as an excuse to skip teaching. Protect play, then put a real skill inside it.
Week 7Physical literacy
Motivation, confidence, competence, knowledge, and the understanding to value movement for life. Not a ribbon. A relationship with your body.
On the floor. Track more than the throw. Did they try? Did they come back? Can they name what their body learned? That is literacy showing up.
On development. Development is measured in identity, not only in form. A literate mover seeks movement at ten, at twenty, at fifty. That is the long arc this path is for.
Watch. Do not turn literacy into another test. If the child leaves liking their body more, the theory worked.
Week 1Cheat sheet: what each theory does
A theory is two answers, not a belief. Read every row the same way: how the child's growth actually changes, then the one thing you do tomorrow.
Worked example — read this first
Proficiency barrier
Seefeldt's idea: if the basics never become reliable, later sport stays closed.
1. How development changes
Without a reliable throw, land, or skip, later games stay closed. The child is not lazy. They hit a wall.
2. What you do tomorrow
Protect those fundamentals. A year of tag is not a throwing curriculum. Do not skip to "the real game" yet.
Every row below is that same pair. Typical is a range. Use more than one lens on the same child.
Maturational theory
How development changes
Skills show up when the nervous system is ready — not when we drill them. Late bloomers are not problems.
What you do tomorrow
Do not force a skip. Offer the next step they can almost do — and make sure they actually see a ball, a beam, a hill.
Dynamical systems
How development changes
The same child can look like they 'can't catch' in a loud gym and can catch with a scarf on a quiet floor. The room is part of the body.
What you do tomorrow
Change one thing — a bigger ball, a quieter wall, a seated start. Watch three tries before you talk.
Hourglass (phases)
How development changes
Sport skills do not stick until the child owns the basics: balance, travel, send and receive. You cannot pour soccer into an empty cup.
What you do tomorrow
Name the phase you are actually in. Teach the movement alphabet all year before you specialize.
Proficiency barrier
How development changes
Without a reliable throw, land, or skip, later games stay closed. The child is not lazy. They hit a wall.
What you do tomorrow
Protect those fundamentals. A year of tag is not a throwing curriculum. Do not skip to 'the real game' yet.
Skill themes
How development changes
The child grows a whole movement alphabet — balance, travel, send — instead of one sport with gaps everywhere else.
What you do tomorrow
Write the session as one theme, one idea, one cue, then play. Today we jump, in different directions, like a cat.
Constraints-led teaching
How development changes
The child searches for a pattern that works, so the skill survives a new ball, a new floor, a new game.
What you do tomorrow
Change one constraint. Count three attempts. Do not lecture the elbows.
Three stages of learning
How development changes
The right stage grows the skill. The wrong one stalls it — too many corrections for a beginner, or boredom for a child who already has it.
What you do tomorrow
Beginner: demo and one cue. Intermediate: vary. Advanced: give them a problem, not a lecture.
Teaching Games for Understanding
How development changes
Children grow game sense and a reason to keep the skill — not only a pretty throw in a line that dies when the drill ends.
What you do tomorrow
Small-sided game, one question, freeze, teach the skill the game just asked for, then back into play.
Self-determination
How development changes
Children who feel choice, skill, and belonging keep moving after you leave. Controlled children comply — then quit.
What you do tomorrow
Offer a real choice. Set a task they can succeed at, then edge it. Say every name.
Mastery climate
How development changes
The cautious child and the already-good child both grow. Rooms that rank 'who won' only keep the already-good, and even they get brittle.
What you do tomorrow
Praise the attempt, not the ranking. Measure against yesterday's self. A race can be 'beat your last time.'
Play as necessity
How development changes
The nervous system changes with joyful repetition. Skill without play fades. Play without any skill is just a party.
What you do tomorrow
Put the skill inside a story or a tiny game. Stop while they still want one more.
Physical literacy
How development changes
Growth is a relationship with the body for life — not a ribbon this Saturday. A literate mover still seeks movement at twenty and at fifty.
What you do tomorrow
Track try, return, and 'can they name what they learned' — not only whether the throw looked pretty.
