Question 1

What is scaffolding in teaching?

Accepted Answer

**Scaffolding** is temporary support that enables a learner to do something they could not manage alone, **withdrawn progressively** as they become able to do it independently. The construction metaphor is exact — the scaffold is not part of the finished building, and leaving it up is a failure.

**The theoretical basis.** The term comes from Wood, Bruner and Ross, building on **Lev Vygotsky's zone of proximal development** — the range of tasks a learner cannot yet do alone but can do with support. Teaching is most effective when aimed at that zone: below it is unchallenging, above it is bewildering.

**What scaffolding looks like in practice:**

**Worked examples**, which have strong evidence behind them. Novices learn more from studying a fully worked solution than from attempting problems unaided — the **worked example effect**. Attempting problems becomes more effective as expertise grows.

**Modelling and thinking aloud**, making the expert's normally invisible reasoning visible.

**Writing frames and sentence starters**, providing structure while the learner supplies content.

**Partially completed problems**, with the learner finishing progressively more.

**Breaking a task into steps** and reducing what must be held in mind at once.

**Questioning** that prompts the next step rather than supplying it.

**Checklists and prompts** the learner eventually internalises.

**The critical and frequently missed part is the fading.** Support that is never removed produces dependence — learners who perform well with the writing frame and cannot write without it. The intended trajectory is **model, then guided practice, then independent practice**, with the teacher deliberately withdrawing at each stage.

**The expertise reversal effect** is the reason this matters: support that helps a novice actively **hinders** a more expert learner, because processing redundant guidance consumes working memory. So scaffolding must be matched to current ability and removed as it grows.

**Differentiation** often means scaffolding differently rather than setting different work.

Question 2

What is the difference between a lecture, a seminar and a tutorial?

Accepted Answer

They differ in size, and size determines everything else about how they work and what you should do in them. Lecture. One academic presenting to a large group — dozens to hundreds. The purpose is

Question 3

Are learning styles real?

Accepted Answer

The popular version, that each person has a style such as visual, auditory or kinaesthetic and learns best when taught in it, is not supported by evidence. It is among the most widely believed ideas

Question 4

Does private tutoring actually work?

Accepted Answer

Yes, with one of the larger effect sizes in education research — but the figure usually quoted comes from structured, trained, one-to-one intervention, and much of what is sold as tutoring bears

Question 5

What is the Feynman technique?

Accepted Answer

The Feynman technique is a study method built on one principle: explaining something simply is the test of whether you understand it. It is named after physicist Richard Feynman, who was known for

Question 6

What is interleaving and why does it feel worse but work better?

Accepted Answer

Interleaving is mixing different topics or problem types within a study session, rather than practising one thing until you move on. Instead of doing twenty problems of type A, then twenty of type B,

Question 7

What is metacognition and why does it predict grades?

Accepted Answer

Metacognition is thinking about your own thinking — specifically, knowing what you know, monitoring how well learning is going, and adjusting your approach accordingly. It is consistently among the
