pub enum ExerciseKind {
Completion,
Practice,
Challenge,
}Expand description
The rung an exercise occupies on the worked→completion→free ladder (Sweller/Renkl fading). Within a section, support only ever fades.
Variants§
Completion
The worked solution minus 1–3 HOLE_MARKER holes — the faded middle
rung between reading an example and writing from scratch.
Practice
Free practice of one (max two) concepts.
Challenge
Multi-concept stretch — also the checkpoint interleaving vehicle.
