Photorealistic editorial image of a modern classroom segmented into three adjacent learning zones: Left (Low) — teacher modeling a concrete hands‑on lesson with young students using blocks, measuring cups, colorful visual cue cards and large worked‑example posters; Middle (Medium) — mixed‑age students in small groups doing guided practice while the teacher circulates, with a collaborative whiteboard, sticky notes and fading sentence‑starters leading to open questions; Right (High) — older students working independently on challenging, open‑ended tasks with laptops, notebooks and a metacognitive reflection journal, minimal teacher presence and signs of transfer to real‑world projects. Warm natural light, shallow depth of field, diverse students and teacher, high detail and clean composition suitable for an article illustration.

Low prior knowledge

Start with concrete experiences (Piaget — concrete operations), many worked examples, heavy modeling, shorter steps.
Use visual scaffolds and real-life contexts.
Medium prior knowledge
Use guided practice, collaborative tasks, and fading prompts from sentence starters → open questions.
High prior knowledge
Offer challenge tasks, prompt for deeper transfer, reduce modeling early; support with metacognitive checks.
