How Self-Marking Tasks Support Students Who Struggle with Working Memory
by Horsham GCSE Mathematics tutor, Richard Linnington
Working memory plays a crucial role in maths learning. Students are often required to hold numbers, rules, and steps in their mind while solving problems. For many learners, this is challenging — and for some, it is a significant barrier.
Self-marking tasks offer a powerful way to reduce this load while improving understanding and confidence.
What is working memory?
Working memory refers to the ability to hold and manipulate information in the mind over short periods of time. In maths, students regularly rely on working memory when following procedures, recalling facts, or solving multi-step problems.
When working memory is overloaded, errors increase and learning slows.
How working memory difficulties appear in maths
- Losing track of steps in a calculation
- Forgetting instructions mid-task
- Difficulty checking answers independently
- Becoming overwhelmed by long questions
These issues are common across a wide range of students, not just those with identified SEND.
Why self-marking tasks help
Immediate feedback reduces memory load
When students receive instant feedback, they do not need to remember what they did several minutes ago. They can correct errors while the thinking is still fresh.
Mistakes become learning opportunities
Self-marking normalises mistakes. Students can try, check, and adjust without waiting for teacher input.
Students stay focused on the task
Without the delay of marking, students remain engaged and are more likely to persist.
A practical self-marking routine
- Introduce the concept with a short explanation.
- Set a small number of practice questions.
- Allow students to check answers immediately.
- Encourage corrections and retries.
- Finish with a reflection question.
Common pitfalls
- Using self-marking as a replacement for explanation
- Allowing students to rush without reflection
- Removing challenge to avoid mistakes
Classroom quick start
Try replacing one traditional worksheet with a self-marking activity that provides instant feedback. Encourage students to correct mistakes rather than moving on.
Final thoughts
Self-marking tasks reduce pressure on working memory by shortening the feedback loop. When used thoughtfully, they support understanding, resilience, and independence — all essential for success in maths.
