The problem with knowledge ‘organisers’

Some basic principles of learning

Learning is a change to long-term memory – the place where all knowledge is stored.  Three main types of knowledge are stored in long-term memory:

  1. Procedural knowledge (e.g. handwriting, walking, calculation strategies etc.), which until a few years ago I would have called ‘skills’. However, I stopped using this term when I learned about the next two forms of knowledge…
  2. Semantic knowledge (e.g. the ‘five-ness’ of the number five; the chronology of events etc.) involves understanding the meanings of facts and how they relate to other facts
  3. Episodic knowledge (e.g. a party you attended, a visit to a museum etc.)

All three types of knowledge are intertwined: One becomes better procedurally (at calculations, for example) the more one understands the semantics of the number system; one becomes more semantically knowledgeable about the number system the more one practises the procedure of calculating. Moreover, the more suitable, repetitive and wide-ranging the episodes, the better the fluency of procedural knowledge and the deepening of semantic understanding.  This is why the term ‘skills’ may not be the best way of describing learning.

‘Intertwined’ knowledge: schema development

Understanding what knowledge actually is, and isn’t, is important in developing sequences of work for students so they acquire the body of knowledge detailed in your curriculum.  This body of knowledge is known as a schema. Schema theory states that all knowledge is organised into groups. Schemas (or schemata) are meaningful groups of knowledge made up of ‘intertwined’ procedural, semantic and episodic knowledge.

Simply providing students with ‘information’ about a topic does little to help them build a schema.  The diagram below shows the difference between information and a schema.

The problem with knowledge ‘organisers’

When looking at knowledge organisers the most fundamental question is ‘How is knowledge organised?’.  In many cases the answer is that it is not organised in any meaningful way.  This makes them information sheets rather than a way of assimilating new information into a schema. Perhaps a more useful term for knowledge organisers might be ‘organised knowledge‘ to make the point that without organisation, the ‘knowledge’ is simply random information.

Knowledge categories

An effective knowledge organiser should organise information into categories that help students to understand where the new information sits in relation to previously learned knowledge. Here are knowledge categories we have created  for geography:

Knowledge categories for geography

This is how a Key Stage 1 topic is organised around the relevant categories:

Knowledge organised around the relevant categories

The idea is that every topic is related to the relevant categories; each time a category comes up again, students are reminded of the knowledge they already have in that category. E.g. ‘Remember in the topic on the United Kingdom we looked at human features, such as The London Eye – a tourist attraction in London? Now we are going to look at how Antartica has no inhabitants – a human feature of this continent.’

Here is another topic, this time from Key Stage 2.  Notice how the same categories are used.
