Scaffolded Task Modifier

What This Skill Does

Adapts a classroom task for a specific language proficiency level while explicitly maintaining cognitive demand — ensuring that EAL students engage with the same thinking as their peers, even when they need language support to do so. The critical design principle is that scaffolding should reduce LANGUAGE barriers, not reduce THINKING. Many well-intentioned task modifications inadvertently lower cognitive demand: giving EAL students a simpler version, removing the analytical component, or replacing an open question with a multiple-choice one. This skill guards against that by producing a modified task alongside an explicit cognitive demand check, verifying that the modification changes the linguistic access route but not the intellectual destination. AI is specifically valuable here because maintaining cognitive demand during scaffolding requires simultaneously understanding the task's intellectual purpose, the student's language level, and the specific scaffolding strategies that support access without reducing challenge — a three-way analysis most teachers don't have time to do.

Evidence Foundation

Gibbons (2002, 2015) established the fundamental principle that scaffolding for EAL students must challenge rather than simplify — the goal is to support students in doing MORE than they could alone, not to reduce what they're asked to do. Cummins (2000) provided the quadrant model showing that tasks vary along two dimensions: cognitive demand (high/low) and contextual support (embedded/reduced). Effective EAL scaffolding moves a task from quadrant D (high demand, reduced context — inaccessible) to quadrant B (high demand, embedded context — challenging but accessible) — NOT from quadrant D to quadrant A (low demand, embedded context — accessible but unchallenging). Hammond & Gibbons (2005) identified two levels of scaffolding: designed-in scaffolding (planned before the lesson — graphic organisers, sentence frames, pre-teaching vocabulary) and interactional scaffolding (contingent teacher support during the lesson — recasting, elaborating, guiding). Vygotsky (1978) established that learning occurs in the Zone of Proximal Development — what the learner can do with support but not yet independently. Walqui (2006) identified six scaffolding strategies for EAL learners: modelling, bridging, contextualising, building schema, representing text, and developing metacognition.

Input Schema

The teacher must provide:

• Original task: The task as designed for the class. e.g. "Write a balanced argument essay on whether school uniforms should be compulsory" / "Analyse the data in the table and explain what it shows about population growth" / "Read the extract and answer the inference questions"
• Target proficiency: The language level to scaffold for. e.g. "Early Acquisition" / "Developing" / "New to English"
• Subject area: The subject. e.g. "English" / "Geography" / "Science"

Optional (injected by context engine if available):

• Student level: Year group
