Effective Revision Strategies

There is a lot of cognitive science research that proves what revision strategies work best for embedding information into the long term memory – which is our goal in relation to exam success. Some of it is common sense, but other aspects may surprise you or challenge your thinking.

There are many time-consuming revision strategies that actually fool us into thinking we have embedded the knowledge into our long term memory. For example, simply re-reading texts or notes has been seen to have a low impact with regard to memory retention, especially considering how much time this can take, but students are happy because this is a relatively undemanding task that takes little mental effort and it feels like effective revision. Re-reading ‘Of Mice and Men’ for an English Literature exam doesn’t have the impact we need, especially given how time consuming it is as a revision activity, therefore other, better, strategies should be undertaken.

Other edu-myths also cloud effective planning for exam revision. There is an old adage abound in education that: “We learn: 10 percent of what we read; 20 percent of what we hear; 30 percent of what we both see and hear; 50 percent of what we discussed with others; 80 percent of what we experience personally; 95 percent of what we teach to someone else.” This is a myth based on no evidence. It has become perpetuated because it is an easily reductive formula, but it is unfounded. David Didau lances this particularly boil to good effect here. We must go beyond these simplifications and seek answers from more reputable research to judge against our experience.

The following strategies are underpinned by more reputable scientific research and evidence:

Information retrieval over re-reading: It may prove more challenging in the short term, but getting students to try to remember the content of a given topic is more effective than making revision notes based on their original content, textbooks etc. ‘Concept mapping’ is an ideal teaching tool for this (think of its popular branding, image and colour laden brother ‘mind-mapping’!). At the end of each week for example, have students attempt to retrieve the information, without their notes or books. They create a hierarchy of connections that they can attempt to organise conceptually.

Collaborative retrieval: Typically we associate revision activities and memory as requiring individual focus. Indeed, there is some evidence that group work can inhibit some learning, but there is evidence that students working in groups can have a positive effect, where students work together ‘cross cueing’ the information they are recalling. Put simply, they help one another remember and retrieve aspects of key information they would not have remembered individually. Also, the social nature of working together can create memory cues that help individuals recall well over time. Of course, any errors in retrieval, either individually or collaboratively, need teacher correction.

‘Spacing’ versus ‘massed’ practice: This finding is common sense really. ‘Spacing‘ is when revising the same information two or three times across a few days improves the likelihood of retaining information in the long term memory (Nuttall, 1999). This may include revising a poem and making connections with another poem, then revisiting the key aspects of that poem in the subsequent lesson, before finally doing a ‘concept map’ at the end of the week to revise the learning from the lessons that week. ‘Massed‘ practice, or ‘cramming‘, can have a good short term effect on memory recall, but it fails in the long term in comparison to ‘spacing’ out revision. There is no exact time or number of days concerning how much ‘spaced’ time should be allocated; however, the research indicted the number of days ‘spacing’ is shorter the nearer the exam. In practical terms, over a half-term, we could revisit a concept after a couple of weeks, but nearer they exam we would cluster a couple more ‘revisions’ of the concept/information.

David Didau has written an excellent blog explaining spacing etc. and the implications for curriculum planning, and what ‘progress’ in learning may look like here.

Using ‘worked examples’: This is the common method of using past exemplars or creating your own through ‘shared writing‘ strategies. It gives students a working template for their revision and reduces obstacles that stops them learning more knowledge. Ideally, teachers should lead model worked examples of exam questions, thereby giving students a clear idea of an excellent answer, before fading back and letting students tackle exam questions independently. Of course, once more, quality feedback is key in this process.

A great blog by Joe Kirby goes into great depth about the ‘why’ of using ‘worked examples’ here.

Regular in-class testing: Drilling answers to tests, under test conditions, can improve both short term and long term memory to boost revision (Roediger et al 2011). Like the retrieval practice of ‘concept mapping’, the very act of retrieval without resources to support proves more memorable than any ‘re-study’ activity. Taking a test can lead to students becoming less confident, therefore quick and accurate feedback is key to making testing highly effective and building confidence. There is research to say that teachers often drastically overestimate what they believe their students to know (Kelly, 1999) so repeated testing is a practical necessity. In terms of learning, there is much research that testing revision material has a positive impact on long term memory in comparison with simply revisiting material.

Another important consideration is that students naturally revise in a ‘massed’ learning style i.e. last minute cramming! It is labelled the ‘procrastination scallop‘ by Jack Michael here. This led to a recommended ‘exam a day’ approach, which forces students to distribute their revision more evenly, rather than just cramming. It may seem excessive, but getting students to do challenging retrieval that informs the teacher what they know and don’t know (and invariably if they have revised or not) regularly, like quizzes etc. could do the job.

A lot less scientific, but a fun revision strategy that works for many:

– Building a ‘palace of memory’ is a much less scientific way of improving memory recall, but it is apparently thousands of years old, originating with the Greek poet, Simonides of Ceos, in the fifth century BC. See this Guardian article for an excellent example of the method in action: http://www.guardian.co.uk/lifeandstyle/2012/jan/15/memory-palaces-lists

How does this equate to a revision programme?

I am now avoiding revision activities or homework revision tasks that recommend simply revisiting information. I will plan to interleave different topics each week, to create the necessary ‘spacing’ between topics (in my English GCSE class this will mean studying poetry for English Literature at the start of the week, the novel and short stories in the middle of the week, ending the week with English Language revision). I will give regular mini-tests, drilling individual answers, with ‘worked examples’ in the first instance to model a good answer. The feedback on their answers will be timely and regular. I want to undertake weekly retrieval activities that reflect upon what they have learnt that week (combining ‘spacing’ and ‘retrieval’)

It is clear that the process of revision happens inside and outside the classroom. Students who possess the grit and resilience to persist with the humdrum nature of revision tasks will have a greater chance at success, but teachers must also identify and plan revision strategies that work. Of course, our experience and intuition about what will work best for our students is important, but we should challenge our assumptions with the wider research that is easily accessible on the web.

  8. Lovely challenge for those establishing revision strategies for their classes.
    What colleagues within secondary need to understand though on the value of testing, is that (certainly during almost the whole of key stage 3) pupils are being socialised to higher learning and skill acquisition. The value of testing per se then exists only to benefit systems where progress is measured through such assessment mechanisms at the end of the year, and that means there is a large american bias in the research…because end of year assessment by test is the american way.
    Craft skills are not best tested every week for example, but can be assessed and immediate feedback given. The higher level skills of GCSE Art, Drama, History, ICT, Resistant materials and PE often don’t exist at the start of the course – so what works for core does not necessarily work for choice/option subjects.
    Suffice it to say that in the wrong hands Year 7,8,9 are becoming the most stressful journey for children because not a day goes by without them being tested and held to account… and we have had that as a formula for too long, and the most recent OECD placement of England at the bottom of the developed nations survey shows that we need to change tack quite dramatically – not to more testing but to the building of an ethic and culture of excellence.
    So one of my most important primers for the last decade or so has been An Ethic of Excellence: Building a Culture of Craftsmanship with Students by Ron Berger, which is an inspiring read and initially places one in such a defensive mind-set of ‘I could not possible do that’ but bit by bit, slowly and steadily schools and teachers can.
