In teaching, “scaffolding” means:

Correct answer: Temporary support. Scaffolding is temporary support from a teacher or peer that is gradually removed as the learner becomes more competent.

• Permanent help: Permanent help would make learners dependent, which is the opposite of scaffolding.
• Lesson plans: Lesson plans are planning documents, not a support technique.
• Structure: “Structure” is too vague; scaffolding specifically means temporary, adjustable support.
