Sorting, matching, quizzes, and the module gate stay behind a free account so scored answers are not public. The teaching notes below are the same cited curriculum.
01
Check | Pass? | Fail symptom
Drag mission has keyboard/alternative path (WCAG 2.2) | Yes | Drag-only completion
Timer does not block accessibility settings | Yes | No pause/extend for reading time
One primary mechanic per beat | Yes | Stacked animations + sort + quiz on one screen
02
WCAG 2.2 treats dragging as something that needs another way to complete the same action. A warehouse path the learner can only draw with a pointer fails that idea, even if the art is careful. Ship a keyboard list that performs the same steps, in the same order, with the same feedback. Timers need pause and extend so a longer Arabic label is not a penalty. Stacking a sort, an animation, and a quiz on one beat fails both WCAG focus and Sweller’s one-mechanic rule. Points and badges without step scoring do not rescue a drag-only mission.
03
Before publish, complete the mission once with a pointer and once with the keyboard, in Arabic and in English. If the keyboard path skips a step or the Arabic layout covers the fail-state text, block publish. A pause control that exists only in the English file is the same defect.
