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)

Scaffolding is the technique designed to help learners reach higher levels of understanding by building on what they already know, with support that gradually fades as they become more capable. In practice, this means introducing new material with clear models and prompts, guiding students through practice with feedback, and then slowly removing those supports so they can tackle more complex tasks independently. As lessons progress, the difficulty increases, but each step is made accessible by the preceding guidance, ensuring that students can handle progressively tougher content without being overwhelmed. While organizing content by difficulty can be useful, scaffolding specifically focuses on providing just-in-time supports and a gradual release of responsibility, which is why it best fits the idea of increasing complexity across lessons.
