Glossary

Plain-language definitions of the ideas we teach and write about — from computational thinking and reward hacking to the original frameworks Lucas Academy uses to talk about learning in the age of AI.

Our frameworks

Ideas we've named and developed at Lucas Academy to describe how kids learn, create, and think alongside AI. Each one is drawn from real projects our students use.

The Human-AI Interface Loop

How a child works well alongside AI: Ask → Inspect → Doubt → Modify → Test → Explain → Ask better. The value isn't the first question — it's the loop of doubting the answer, changing it on purpose, and testing whether the change helped. See Learning in the age of AI.

Thinking artifact

Any visible thing a student makes that reveals how they thought — the work plus the trace of judgement behind it: a fixed line of code, a bot's settings and the game it played, a corrected AI answer. See Thinking artifacts.

The Discovery Loop

Learning through attention: Observe → Question → Explore → Build → Reflect → Share, then observe again. Learning starts with noticing, not answers. See Computational studio art.

The Creation Ladder

Creativity as a climb, not a sudden leap: Consume → Understand → Modify → Create → Teach → Contribute. Each rung tends to leave a richer thinking artifact than the one below. See Thinking artifacts.

Computational studio art

An art practice that treats algorithms, computer vision, and simulation as studio materials a child questions, shapes, and transforms — rather than asking a machine to generate a finished picture. See Computational studio art.

Concepts & techniques

Widely used ideas from computer science, math, and art that kids meet — by doing — across the arcade, the camp, and the studios.

Computational thinking

Solving a problem the way you would if you had to explain it to a computer: decomposition, pattern recognition, abstraction, and clear step-by-step algorithms. A way of thinking, not a programming language. See What is computational thinking for kids?

Decomposition

Breaking a large problem into smaller, doable parts. One of the four moves of computational thinking.

Pattern recognition

Noticing what repeats, so a solution can be reused instead of rebuilt each time. One of the four moves of computational thinking.

Abstraction

Ignoring the details that don't matter and keeping the ones that do — like a subway map that keeps the route and drops the geography.

Algorithm

A clear, ordered set of steps that reliably solves a problem — precise enough that another person, or a computer, could follow it exactly.

Debugging

Finding and fixing the one thing that's broken in an otherwise working system — a core skill for reading and judging code, including code an AI wrote.

Reward hacking

Winning by exploiting the letter of a rule or scoring system rather than its intent. Kids meet it firsthand when a tuned bot "wins" through a loophole; it's also a central idea in AI safety. See Games as thinking laboratories.

Game theory

The study of strategic decisions in which each participant's best move depends on what the others do. At Lucas Academy it shows up in snake-bot duels and Monkey Republic.

Nash equilibrium

A combination of strategies in which no player can do better by changing only their own strategy. Kids meet the intuition when no single bot always wins and the best move depends on the matchup.

Law of reflection

A ball or ray leaves a surface at the same angle it arrived, measured from the perpendicular — in vectors, v' = v − 2(v·n)n. It's the law of light reflection and the core rule of Breaker. See The geometry of a bounce.

Reaction-diffusion

A pair of simple rules, modeled on interacting chemicals, that grow spots, stripes, and coral-like patterns. Used as an art material in the Computational Art Studio.

Voronoi diagram

A way of dividing space into regions — one per seed point — where every location belongs to its nearest seed. It turns a photo into mosaic- or stained-glass-like cells.

Segmentation

Dividing an image into meaningful regions — the parts a computer treats as "one thing." A form of computer vision used to reinterpret photos as art.

Computer vision

Getting a computer to extract meaning from images — finding edges, regions, colors, or shapes. In the studio, children control what the machine sees rather than accepting a finished output. See Computer vision as a paintbrush.
