Guided collections

Use compact lesson sets when topic routes, tracks, and challenge entry points should stay in one authored order.

These collections do not create a new LMS layer. They only bundle existing concept pages, starter tracks, topic routes, and challenge surfaces into bounded teacher-friendly sequences, while the recommended goal paths below keep common objectives explicit without hiding the authored structure.

Open concept library

What these reuse

Existing pages stay canonical. The collection layer only keeps the order explicit.

Every collection here still lands back inside the same concept framework, starter track pages, challenge hub, shareable deep-link surfaces, and local-first progress seams that already power the rest of the product.

Browse topic routesOpen challenge hub

10 guided collections

Each one is intentionally compact instead of turning the product into a course CMS.

43 ordered steps

Steps can point to concepts, tracks, challenge checkpoints, and other existing surfaces without duplicating content.

55 covered concepts

Coverage still comes from canonical concept identities, not one-off lesson page props.

1079 estimated minutes

Time stays approximate and compact so the collection does not pretend to be a full schedule builder.

Specific learning goals

Choose an authored path when the goal is already clear.

These goal cards stay transparent on purpose. Each one points back to existing topic routes, starter tracks, guided collections, concept pages, and concept-bundle builders instead of inventing a new opaque recommendation engine.

Local-first, with synced progress only filling in when this browser is empty.

Build wave intuition from one oscillator outward

Start on the topic route, keep the Waves Evidence Loop compact, and reuse the authored wave order before widening into the rest of the branch.

The topic route gives the branch a map, the guided collection keeps the story compact, the waves starter track preserves the authored order through sound, pitch-versus-loudness cues, beats, the Doppler shift, and air-column resonance, and the interference revisit gives one clean place to test whether the wave picture still feels concrete.
