Practise recalling
Answering from memory is an established research topic called retrieval practice. It shapes our use of questions alongside notes.
Roediger & Karpicke, 2006 →How we build it · Primary Science
Understand it. Practise it. Come back to it.
Start with a small science idea, connect it to an observation, then practise recalling and explaining it. Our Primary learning design draws on published research and the MOE 2023 Primary Science syllabus.
Different ways to work through one idea
pick what helps
These activities connect explanation, exploration and practice. Choose the one that helps with the concept you’re working on.
Understand the idea
Notes: read the key explanation and diagram. Look for the common mistake and why it doesn’t fit the science.
Recall and explain
Learn: answer short questions and use feedback to revisit your thinking. Written-explanation activities cover part of the collection and are growing.
Test a prediction
Lab: change a circuit, a light path or another scientific model. Observe the result and connect it to your explanation.
Apply the concept
Practice: use quests and practice questions to work with the same idea in different situations.
Bring ideas together
Exam practice: use P5 practice papers and structured-answer questions to practise reading evidence and explaining your reasoning.
Return to an idea
Review: revisit earlier concepts and mistakes through guided practice. We’re still refining the review experience.
Activity coverage varies between chapters. The number of chapters doesn’t establish complete syllabus coverage or exam readiness.
Why we chose this approach
Revisit over time
Spaced practice spreads learning across sessions. This research shapes our review design; it doesn’t give one ideal schedule for every child.
Cepeda and colleagues, 2006 →Explain what happened
The lab asks children to predict, observe and connect a result to the science. Worked examples and answer practice give them ways to put that into words.
