Which technique is used to organize materials so that complexity increases gradually across lessons?

• A. Structural grading
• B. Scaffolding
• C. Subtractive bilingualism
• D. Simplification

Answer: (A)

Structural grading organizes content so that complexity increases gradually across lessons. It designs a sequence where the material, tasks, and language forms start simple and progressively become more demanding, allowing learners to solidify foundations before tackling harder elements. For example, a grammar unit might begin with the present simple of common verbs, then add time expressions and question forms, and later introduce more complex sentence structures. This approach helps ensure learners have the necessary prerequisites and can manage cognitive load as they advance.

While scaffolding is about providing support within tasks to help learners access challenging material, the technique here is about the overall progression of content across lessons. Subtractive bilingualism focuses on language replacement dynamics rather than curricular sequencing, and simplification refers to making material easier rather than organizing a step-by-step increase in complexity.
