Expand description
“Now you try” exercise block for the Syntax Guide.
The reader writes code (Imperative — graded by exact program output), a
page (Web — graded by the page’s own ## Test blocks) or FOL (Logic —
graded structurally by the Learn grader) and checks it in place. The reference solution never reaches the DOM; the guide’s test
suite proves it grades correct before it can ship.
Pedagogy surface: the kind badge names the exercise’s rung on the worked→completion→free ladder (Sweller/Renkl), hints disclose one at a time on demand and never spoil (Bloom’s corrective tutor), and every graded result feeds the SM-2 deck so the exercise resurfaces before it fades — a clean pass without hints schedules further out than a rescued one.
