Improving pupils’ working memories can help them, both with exams and in preparation for higher study and working life. Margaret Reeve offers some quick CPD

One of the most fundamental areas of development for teachers is in understanding differentiation strategies – the techniques used to help pupils make good progress, irrespective of their starting points. It’s the process through which teaching is tailored to support different pupil capabilities.

Working memory plays a critical part in the way pupils learn, but has limitations. Find ways to overcome those limitations, and you will enhance pupils’ capabilities.

What is working memory?

Alan Baddeley and Graham Hitch (1974) put forward a model of working memory as a way to better explain short-term memory. The term indicates that this type of memory is concerned with the work we do moment to moment, as opposed to long-term memory which can be conceptualised more like a store.

Part of the importance of the model is the way in which it demonstrates how working memory can be easily overloaded, disrupted or interrupted – leading to a loss of focus and a reduced efficacy. On average, working memory is limited to roughly seven pieces of information (plus or minus two) – nine is pushing it and would mean that students struggle to learn and retain.

Supporting working memory

The research on working memory connects closely to differentiation. Helping your pupils to understand and overcome the limitations of their working memory will make it easier for them to complete tasks, engage with learning, and take on challenges. It will also give them a sense of what they can do to assert greater agency over their learning.

The following simple working memory strategies might give your pupils a chance to take control of how they engage with learning, leading to better results all round:

Using scrap paper

  • Definition: Any piece of rough paper on which pupils can make notes.
  • Example: A pupil writes their thoughts down on a piece of scrap paper before they start writing.
  • Result: The pupil frees up space in their working memory, allowing them to concentrate on the act of writing. This makes it easier for them to target their efforts.

Using checklists

  • Definition: Any series of items a pupil uses to check that what they are doing is right.
  • Example: PEE – Point, Evidence, Explain. A pupil uses this to check their paragraph structure as they write.
  • Result: The pupil doesn’t have to think through all the possibilities on every occasion. Using the checklist frees up working memory, which they can target on the task in hand.

Designing sub-tasks

  • Definition: Divide a main task into a series of sub-tasks.
  • Example: In a science lesson, the teacher divides a large task (creating and running an experiment) into a sequence of separate sub-tasks.
  • Result: Pupils can focus on one task at a time, devoting their entire working memory to each one in turn.

Using verbal rehearsal

  • Definition: Pupils verbally rehearse their thinking prior to applying it.
  • Example: In a geography lesson, pupils discuss the pros and cons of renewable energy in pairs before writing a paragraph outlining their thoughts.
  • Result: Verbal rehearsal provides space in which students can refine, edit and order their thinking. Subsequent application of the thinking is thus much easier.

Using mini-whiteboards

  • Definition: An alternative to scrap paper. Writing can be wiped away, meaning it is not fixed.
  • Example: A pupil uses a mini-whiteboard to help do a complex calculation in a maths lesson.
  • Result: The mini-whiteboard expands the capacity of working memory. The pupil writes numbers on it, freeing up space and making it easier to persist with the calculation.

Strategies into practice

Discuss these strategies with your colleagues. Are you using any of them already? If so, do you think about them as ways in which pupils can expand the capacity of their working memory?

To experience how the strategies actually work, try out one or two of them on yourself in your own work. As you do, consider how they allow you to overcome the biological limitations of your mind.

To start embedding these working memory strategies in teaching across your school, begin by introducing your team to two of the strategies and then plan how you will utilise them in lessons. Work out what kind of evidence you will need to collect to judge and demonstrate the impact of the techniques. Then give them a trial.

Remember that not all new teaching tools will work straight away. Teachers and pupils may need time to get into the habit of using a new strategy effectively.

The key is to continually monitor and adapt. For example, you could reflect on your use of the working memory strategies by observing how pupils interact with them, how they start applying them unprompted to tasks in hand and, over time, how pupils’ subsequent performance differs from before you used the strategies.
