Try it first. Read later.

3–6 meaningful locations on one site photo — leak points, inspection points, system parts.

An installation photo with 2–3 deliberate faults; the learner marks what is wrong. Strong for inspection and safety.

A section diagram (membrane layers, substrate layers) to be named — drag labels onto parts.

Material ↔ use, tool ↔ task, symptom ↔ cause. Screen S13 in PL01 is a real example.

Items belong in 2–4 bins (allowed / not allowed, floor / wall / roof).

One rule, many items; the learner predicts whether each item passes or is rejected, and every rejection has a reason. Good for specifications and conditions.

A 4–7 step procedure where order matters — surface preparation before coating, inspection before closing.

A procedure revealed one step at a time; the learner controls the pace but cannot skip.

Correct vs wrong installation on the same image; condition before vs after treatment.

One variable changes the outcome — coating thickness, slope, drying time — and the learner sees the effect.

Specification vs site reality; plan vs as-built; what should be vs what happened.

Every wrong answer is a common misconception with its own reason; the learner may try all of them before the right answer opens. Strong for “why not this one”.

Site situation → choice → consequence → next choice. 2–3 levels, one correct path and educational wrong paths.

Items that must be confirmed before work starts — PPE, surface condition, weather. The learner ticks; missed items are explained.

A list of materials, tools or steps containing 1–3 wrong items; the learner removes them.

Term → definition, image → name, question → answer. 4–6 cards.

Content that is genuinely long but splits into 3–5 independent sections. The safest way to avoid scrolling.

A layered system — waterproofing, insulation, substrate — opened one layer at a time with name and function.

A stop-work decision simulation: conditions change, the learner must hold the process when a condition is not met. No known K1 screen yet.

Formal assessment at the end of a topic; every option shows its rationale after answering.

A 1–3 minute demonstration video that stops at 1–2 points for one question.

Material quantity or coverage for a given area; 2–3 inputs, one result. Only if the formula comes from the module source.

The learner identifies an issue that is not an immediate blocker and parks it with an owner so the main work can continue. No known K1 screen yet.
