Describe a Change Over Time

Worked classroom example

Science

Worked example

For Describe a Change Over Time in Science, set a prompt about a fair test. Ask learners to name what changed in the learner’s understanding and support it with one specific piece of work. Model a short response with the subject evidence visible; have learners underline the part that meets the criterion and revise one vague or unsupported phrase.

Use this example to make the language move visible. Select subject content appropriate to the class’s age and prior knowledge.

Teaching sequence

1. Set a short Science prompt and prepare before-and-after data. For Describe a Change Over Time, show the success criterion and model one planning choice while leaving the subject reasoning to learners.
2. Learners produce the response required by Describe a Change Over Time: Name what changed in the learner’s understanding and support it with one specific piece of work. Allow a brief oral rehearsal or note plan, then draft in the form the prompt requires.
3. Use this check: “Which part of the success criterion can you see in this sentence?” Ask learners to apply the criterion to fresh content, underline where they meet it and make one purposeful revision.

Prepare

Use before-and-after data. Choose a second example that checks the same language move without repeating the original answer.

Classroom task

Give each learner before-and-after data. They jot three key words, draft a response in four minutes, then underline the sentence that answers the task.

Check independent transfer

Check the draft against the task and remove any sentence that does not help the reader understand the result.

Collect a response on fresh content. Note what was achieved without the model, partner or teacher prompt, then choose one next teaching step.

Teacher language

Teacher language

Which part of the success criterion can you see in this sentence?

Respond to the learner

Identify one successful meaning or language choice. Ask about one gap, allow thinking time, then invite a revision. Check the revised move again on a fresh example.

Adjust support and challenge

Offer a brief model, useful vocabulary and partner rehearsal where needed. Keep the subject goal; reduce one prompt on fresh content and record what was independent.

More support

Use oral rehearsal, a brief model and a limited sentence frame. Remove one support for the fresh writing task. Allow familiar-language notes or another response mode when checking subject understanding.

Greater independence

Change the content, evidence or audience. Remove the completed model and ask learners to explain a choice. Increase subject complexity only when it fits the curriculum and prior knowledge.

Choose the next step

If subject meaning is insecure, reteach the concept. If the concept is understood but the English is unclear, model one useful language relationship and invite a fresh response.
