Practical strategies for everyday teaching — based on Dylan Wiliam & Tom Sherrington

Why Formative Assessment?

Not another checklist — a mindset shift for responsive teaching.

1

See What Students Think

Surface misconceptions and gaps in real-time — before they compound. Every student, not just the ones who raise their hands.

2

Give Feedback That Moves

Replace vague praise with specific, actionable next steps students can use immediately to improve their work.

3

Adjust While It Matters

Change course during the lesson, not after the test. Teaching becomes a conversation, not a broadcast.

The shift: Formative assessment isn't something you bolt onto a lesson. It's the difference between "I taught it" and "They learned it." When done well, both you and your students use evidence to decide what happens next.

Daily Moves for Every Teacher

Four strategies from Dylan Wiliam you can weave into any lesson. Tap to expand.

Clarify Success

Before

Show students what excellence looks like before they begin. When learners understand the target, they can self-assess and peer-assess meaningfully.

Try This

"Here are two opening paragraphs. Which one hooks the reader better? Why? Let's build our success criteria from that."

Ask with Purpose

During

Design questions that reveal understanding, not just recall. Use "no hands up" and think-pair-share so every student is accountable.

Try This

"Why might the author have chosen that word instead of a simpler one? Talk to your partner for 30 seconds, then I'll pick someone."

Check All, Not Some

During

Make every student's thinking visible simultaneously. Don't rely on volunteers — they're usually the ones who already understand.

Try This

"On your whiteboard, write the literary device used in this line. Hold it up on 3… 2… 1… show me."

Feedback to Action

After

Feedback is only useful if students do something with it. Build in time for students to respond, revise, and improve immediately.

Try This

"I've underlined one sentence in your essay. Rewrite it using a more precise verb. You have 3 minutes."

The 5 R's of Action Feedback

Tom Sherrington's framework — match your feedback response to what the student needs.

Which R Should I Use?

Pick a scenario to see a recommended response.

Recommended: Revisit

Careless errors suggest the student knows the material but wasn't careful enough. Asking them to find and correct their own errors builds metacognition.

Say this: "I've marked 3 errors. Find them, fix them, and write one sentence explaining what you'll check for next time."

Recommended: Re-learn then Rehearse

If the underlying concept isn't there, more practice won't help. Guide them back to the source material first, then give fresh practice.

Say this: "Go back to the worked example on the board. Read through it step by step, then try this new problem."

Recommended: Redraft

The foundations are there but the quality needs lifting. Targeted redrafting of a specific section is more effective than vague encouragement.

Say this: "Your second paragraph has the right idea but needs a stronger example. Rewrite just that paragraph."

Recommended: Re-learn then Revisit

Repeated errors suggest a persistent misconception. They need to re-engage with the concept, then deliberately practice the correction.

Say this: "Let's look at this rule together. Now — explain it to me in your own words before you try again."

Recommended: Research

Fast finishers who skim the surface need an extension that deepens rather than just adds volume. Research connects learning to the wider world.

Say this: "Great start. Now find a real-world example where this concept applies and explain how it connects."

What to Try Tomorrow

Pick what fits your lesson. You don't need all of these — start with one.

Quick Wins

0 / 6

Start with 3 recap questions

Begin class by quizzing previous content to activate prior knowledge.

Lesson start

Cold call with wait time

Ask a question, wait 3-5 seconds, then randomly select a student.

During lesson

Show-me whiteboards

All students answer on whiteboards and reveal simultaneously. Scan the room.

During lesson

Think-Pair-Share a hard question

Pose a genuine dilemma. Silent think, partner discuss, class share.

During lesson

Give DIRT time

Dedicated Improvement and Reflection Time — students act on feedback in green pen.

After feedback

Exit ticket — 1 question, 2 minutes

One well-chosen question at the end. Scan responses before planning tomorrow.
