# What Is A Spiral Curriculum: A Teacher’s Guide to What, How And When To Implement

**A spiral curriculum is a popular model to consider when looking at how you design and enact your curriculum. **

With the Ofsted inspection framework refocusing on curriculum intent, implementation and impact, school leaders are looking with a renewed focus on how to structure learning within their school, both across and within years and subjects.

Here former curriculum lead Aidan Severs provides a teacher and school leader perspective on the spiral curriculum to support those of you involved in developing your own high quality curriculum and assessing all the available curriculum models and structures.

The spiral curriculum is a curriculum model in which a sequence of topics or themes are revisited in turn with the complexity of the content increasing each time learners encounter the topic or theme.

The model suggests that teachers and school leaders can see learning as an upward spiral, with foundational concepts being taught to begin with and then added to, or built upon, as the spiral loops upwards, or as prior knowledge is revisited.

## Why consider a spiral curriculum

This curriculum model allows for previous learning to be reinforced as well as allowing for related new content to be taught and learned in the context of what has already been learned.

Although the concept of the spiral focuses on the revisiting of themes, it also has the sequencing of these themes at its heart. It proposes that before a learner revisits a particular theme, they may also need to have learned other content found within other themes.

Therefore, the spiral curriculum model supports the idea that a necessary part of learning is the creation of schema, or mental models, where links between material are made as the information is organised and stored in the mind of the learner.

## Origins of the spiral curriculum

The spiral curriculum model was proposed and developed by Jerome Bruner in the 1960s and was discussed in his publication entitled ‘The Process of Learning’. In it, he works with the hypothesis that “any subject can be taught effectively in some intellectually honest form to any child at any stage of development” (p33).

Here Bruner references the work of constructivist theorist Jean Piaget, particularly his idea that children move through four different stages of cognitive development which dictate how they learn.

### The spiral curriculum in academic literature

In describing the spiral curriculum, Bruner writes: “…basic ideas… are as simple as they are powerful… to use [these basic ideas] effectively, requires a continual deepening of one’s understanding of them that comes from learning to use them in progressively more complex forms… early teaching… should be designed to teach these subjects with scrupulous intellectual honesty, but with an emphasis upon the intuitive grasp of ideas and upon the use of these basic ideas. A curriculum as it develops should revisit these basic ideas repeatedly, building upon them until the student has grasped the full formal apparatus that goes with them.” (p12-13, Jerome. S. Bruner (1960) The Process of Education, Harvard University Press)

Harden and Stamper summarise that “a spiral curriculum is one in which there is an iterative revisiting of topics, subjects or themes…. A spiral curriculum is not simply the repetition of a topic taught. It requires also the deepening of it, with each successive encounter building on the previous one.” (R.M. Harden & N. Stamper (1999) What is a spiral curriculum?, Medical Teacher, 21:2, 141-143 )

## Key principles of a spiral curriculum

Harden and Stamper go on to identify 4 key features of Bruner’s spiral curriculum:

Over time:

- Topics are revisited
- Levels of difficulty increase
- New learning is related to previous learning

And that as a result:

- The competence of students increases

## Spiral curriculum in maths

When it comes to maths, Bruner himself gives an example of how a spiral curriculum model is useful: “If the understanding of number, measure, and probability is judged crucial in the pursuit of science, then instruction in these subjects should begin as intellectually honestly and as early as possible in a manner consistent with the child’s forms of thought. Let the topics be developed and redeveloped in later grades.” (p53-54)

There are many popular maths schemes of work for the Primary curriculum. One of the popular schemes has been designed and refined by White Rose Education. The White Rose Maths scheme of learning follows a block based structure for each year group that spirals back to each topic throughout the primary phase. The White Rose maths scheme of learning encourages learners to revisit and build upon prior knowledge each year.

## Spiral curriculum examples

There are plenty of examples in the maths national curriculum of topics spiralling around, being introduced, then revisited, with new, more difficult, concepts being taught.

### Fractions in a spiral

Third Space Learning’s resources build upon skills throughout the school year and are designed to reinforce past learning, ensuring that students understand the basics before diving deeper into each topic.

**Let’s look at fractions as an example:**

Fractions are introduced in Year 1, where children are taught to recognise, find and name a half as one of two equal parts and a quarter as one of four equal parts of an object, shape or quantity.

In Year 2, this is built upon with children being taught to recognise, find, name and write fractions \frac{1}{3}, \frac{1}{4}, \frac{2}{4} and \frac{3}{4} of a length, shape, set of objects or quantity, to write simple fractions for example, \frac{1}{2} of 6 = 3 and to recognise the equivalence of \frac{2}{4} and \frac{1}{2}.

#### Fractions in Year 1

In Year 1 children learn a foundational concept: things can be split into equal parts, and when we do this, there are names for the parts created. It’s perhaps a concept that they have come across in their early years of life; however, the inclusion of it in the curriculum formalises the concept, marking it out as something important in mathematical thinking.

#### Fractions in Year 2

The Year 1 curriculum content is then built upon in Year 2, particularly in that children are given learning experiences which introduce them to the mathematical notation for the concept, non-unit fractions, the concept of being able to split something into any number of parts and the idea that some written fractions are equivalent.

Although this might be considered a big leap from one year to the next, it’s easy to see how the Year 1 content paves the way for the Year 2 content, and how the Year 2 content revisits and adds complexity to what has gone before.

#### Fractions in year 3 and tying together different concepts

The Year 3 content builds again on what children been taught in the previous two school years with some concepts being revisited and expanded (e.g. recognise, find and write fractions of a discrete set of objects: unit fractions and non-unit fractions with small denominators), and other new related ideas being introduced: in Year 3 children build on their prior knowledge of fractions, learning that they can be recognised and used as numbers.

Something else happens in Year 3, too. Since Year 1, there have been several other topics spiralling upwards. One of these topics is addition, another is subtraction. During key stage 1 children have learned to add sufficiently enough for them to begin to bring together knowledge from two different topics.

In Year 3 they are taught to add and subtract fractions with the same denominator within one whole. This is an example of how new learning is related to previous learning, and of how the complexity increases, this time this is achieved by the combining of knowledge from different, previously taught topics.

#### Fractions in Year 4 and how fractions relate to decimals

When children get to Year 4, decimals are introduced alongside fractions, building on the concept that numbers exist which aren’t whole, introducing children to another common way to represent these not-whole numbers. Children are expected to find equivalences between fractions and decimals and are also taught to carry out further addition and subtraction of fractions, this time where the answer may be more than one whole.

#### Fractions in Year 5: fractions with other operations

By the time children are in Year 5, they build on their previous knowledge of the number system, calculations, fractions and decimals, particularly focusing on equivalent fractions and converting fractions from one form to another. They also begin to multiply fractions by a whole number, having spent plenty of time in previous year groups learning how to multiply whole numbers. In addition, percentages are introduced as a further way to represent numbers which aren’t whole.

#### Fractions in Year 6: calculating with fractions

In Year 6 children are taught to develop their ability to calculate with fractions, not only with the inclusion of the division of fractions by whole numbers, but in the complexity of the fractions involved e.g. involving different denominators and mixed numbers.

## Benefits of a spiral curriculum

There are several advantages to designing and using spiral curriculum, such as:

### Securing the basics and retaining knowledge

The most obvious is the focus is on starting with the basics, placing the emphasis on how important it is for pupils to grasp foundational concepts before they move on.

The fact that topics are repeated allows pupils to revisit their prior learning, recalling it and using it in new ways, thus aiding retention and leading children to a deeper understanding of the content they have been taught previously before learning new, associated content with an increased level of complexity.

This move from simple concepts to complex concepts over time, with content linked to what is thought to be developmentally appropriate is a key feature of the spiral curriculum approach – the benefits of this are that children are introduced to complex topics early on, but in such a way that they can understand them.

An alternative curriculum model may decide that because it is so difficult to know how to multiply fractions, there is no point in teaching finding a half in year 2, and that children should wait until they are developmentally ready to access higher level concepts such as the multiplication of fractions before having anything to do with them.

### Integrating different bodies of knowledge

A further benefit of a spiral curriculum is how topics that have been studied previously can begin to be integrated. By bringing together knowledge from different domains within the curriculum area, children are encouraged to use and apply different concepts with a degree of fluency as they new solve problems, going beyond recall of discrete facts to an application of their knowledge and skills.

### Logical sequencing

This integration is supported by another benefit of spiral curriculum: they are logically sequenced. Spiral curriculum design recognises, particularly in a well-structured subject like maths, that as children learn more, they will need to make more connections between content in their future learning. Curricula are then designed to ensure that children are taught content in an order that begins with the simplest, most foundational concepts in each topic or domain, before introducing units of work that require the use and application of knowledge and skills from more than one of these domains.

## Disadvantages of a spiral curriculum

A spiral curriculum does not fit into every context and can have limitations.

### Does not translate into every subject

A spiral curriculum is better suited to some subjects than others. For example, maths and science are more fact-based than others, such as the art subjects which are more subjective. Although some skills in arts subjects could be seen to be introduced and built-upon incrementally, it wouldn’t be the case for all the content within those subjects.

### Not all learning is linear

The spiral curriculum model is based on the idea that learning is a linear process; however, it isn’t always. A spiral curriculum model may not be the best way to make the links between interconnected ideas within a subject, for example, how multiplication and division are commutative. If multiplication is treated as two separate topics, and are not studied as one, the curriculum is less likely to support the development of the mental models which associate the two concepts.

### It can lead to misconceptions

When pupils are taught concepts at an age-appropriate level, it might be the case that this learning ends up being superficial because they are not yet cognitively able to grasp the nuances or full extent of the concept. Where this is the case, it may be true that later on, when topics are returned to, this superficial understanding has led to children having maths misconceptions that need ‘unlearning’.

### Gaps in time can hinder conceptual understanding

In addition to this, the number of topics inserted into a spiral curriculum may dictate the space between topics. To take our earlier example, fractions may be taught as a unit or topic once a year, resulting in children forgetting in the interim what they have previously been taught.

A spiral curriculum such as this which also has no regular review of content in the interim period between topics risks pupils forgetting what they were taught and teachers having to re-teach rather than remind when it comes round to teaching the topic again. When teachers have to do this, they lose time which should have been spent on teaching the new content, resulting either in teaching being rushed, or content not being taught at all.

### Blocks versus interleaving

The spiral curriculum is usually blocked: topics are covered over a 2 or 3 week period, depending on the number of objectives considered to be part of that topic. Research has shown that interleaved practice, an approach in which maths problems are rearranged so that practice tasks include different kinds of problems, improves mathematics learning.

When topics are taught in blocks – 3 weeks on addition for example – the kind of practice children get is blocked and they are not required to think about other kinds of problems, other areas of the maths curriculum and therefore are not selecting solutions but simply carrying out the same procedures over and over again.

When practice is interleaved, children will be faced with problems taken from any topics that they have studied so far, thus requiring them to recall what they have learned and to choose and apply a range of strategies based on what is appropriate to the problem. Interleaving is not usually a feature of spiral curriculum.

An alternative curriculum model that is built upon the fact that much of the content of the maths national curriculum is interconnected might be preferable, although as we have seen, there are ways to use a spiral curriculum to ensure these links are being made.

For example, a spiral curriculum could conceivably teach multiplication and division as one topic, highlighting the commutativity right from the start. However it is done, a maths curriculum which is rich in deliberately-made links is crucial to fluency and the using and applying of maths knowledge and skills.

## How can a spiral curriculum help your school?

### How to introduce a spiral curriculum

It may be the case that your school’s curriculum already is developed to be a spiral curriculum. Indeed, the maths national curriculum is suggestive of a spiral curriculum, especially where schools take the headings in each year group and regard these as whole topics to be worked through in one or two blocks, starting with the most foundational of objectives.

Before developing the curriculum in your school, a good starting point would be to understand the extent to which your curriculum could be considered to be a spiral curriculum.

### Developing a spiral curriculum

To develop a spiral curriculum, an intimate knowledge of the maths national curriculum will be required, as well as constant reference to it during the curricula’s creation.

Curriculum developers will be aided by the fact that the national curriculum already groups mathematical content into topics or domains: number (taking in place value, addition, subtraction, multiplication, division, fractions, decimals, percentages), ratio and proportion, algebra, measurement, geometry (covering properties of shape and position and direction) and statistics.

Curriculum developers may want to reconsider the groupings made in the national curriculum to ensure that concepts which are linked are not taught in isolation, however the document will provide a good starting point.

If developing a spiral curriculum, schools should bear in mind the key principles outlined above: topics should be revisited, the levels of difficulty should increase and explicit links between old and new learning should be made.

### Understanding the purpose of a spiral curriculum

Just as important for curriculum developers to remember is the purpose of doing all this: to increase the competencies of the pupils. This should be a guiding principle for any changes made and introduced.

If you do identify ways in which your curriculum is deficient, and you think a spiral curriculum is the way forward, a significant period of development will be required. It won’t be possible to change a unit here and there, as this will have a knock-on effect later down the line. This process should involve retaining the strong elements of the previous curriculum whilst rearranging and strengthening the weaker aspects.

### Moving between curriculum models

Any move from one curriculum to another needs to be managed with care. Leaders should consider if a wholesale move from one to another, with every child in every year group starting on the new curriculum at the start of a new year is a wise decision.

Most curricula build on previously taught content, therefore a change of curriculum, say, in Year 3, may mean that a child doesn’t have requisite prior knowledge to access the prescribed Year 3 content, leading to teachers having to track back and teach foundational concepts, leaving them less time to teach the new content.

A simple alternative to this is to roll out the new curriculum year by year, with the youngest children starting the new curriculum each year, and the older children continuing to work on the old curriculum until eventually, the first year group to commence working with the curriculum have moved their way through the school, by which time all children will be working on the new curriculum.

### Applying the curriculum in the classroom

Beyond the writing of the curriculum, one will need to consider the pedagogical approaches that will be necessary to facilitate this curriculum in the classroom. Curriculum developers should think about how the content in the curriculum will be best taught, selecting teaching practices that are well-matched to the content.

Leaders may want to consider how the curriculum and its delivery will be appropriate for children with differing needs, for example, using interventions to ensure that children have grasped the foundational concepts before moving on to learning more complex concepts.

Once this significant piece of curriculum development work is done, school leaders will need to invest in staff training and resourcing and any other necessary preparations for the delivery of the new curriculum. A curriculum on paper is all very well, but it is in the classroom where it really matters.

### Communicating the reasons behind changing curriculum models

Leaders should ensure that they understand and can articulate why changes have been made to the curriculum and this should be communicated clearly to teachers and other staff members.

To get further buy-in from staff, leaders can provide the resources that teachers need, show that they trust staff to try things out, make mistakes, and provide feedback on the new curriculum, and explain to the staff that they expect the process of implementation to take time as staff get to grips with the new curriculum. In addition to this, staff members should know how the new curriculum should be taught, with any active ingredients made very clear to them.

“the basic ideas that lie at the heart of all science and mathematics and the basic themes that give form to life and literature are as simple as they are powerful. To be in command of these basic ideas, to use them effectively, requires a continual deepening of one’s understanding of them that comes from learning to use them in progressively more complex forms… The early teaching of science, mathematics, social studies, and literature should be designed to teach these subjects with scrupulous intellectual honesty, but with an emphasis upon the intuitive grasp of ideas and upon the use of these basic ideas. A curriculum as it develops should revisit these basic ideas repeatedly, building upon them until the student has grasped the full formal apparatus that goes with them.” (p12-13)

general claims that can be made for teaching the fundamental structure of a subject:

- understanding fundamentals makes a subject more comprehensible (p23)
- unless detail is placed into a structured pattern, it is rapidly forgotten… Detailed material is conserved in memory by the use of simplified ways of representing it (p24)… What learning general or fundamental principles does is to ensure that memory loss will not mean total loss, that what remains will permit us to reconstruct the details when needed. (p25)
- an understanding of fundamental principles and ideas, as noted earlier, appears to be the main road to adequate “transfer of training.” To understand something as a specific instance of a more general case-which is what understanding a more fundamental principle or structure means-is to have learned not only a specific thing but also a model for understanding other things like it that one may encounter. (p25)
- by constantly reexamining material taught in elementary and secondary schools for its fundamental character, one is able to narrow the gap between “advanced” knowledge and “elementary” knowledge (p26)

“the curriculum of a subject should be determined by the most fundamental understanding that can be achieved of the underlying principles that give structure to that subject. Teaching specific topics or skills without making clear their context in the broader fundamental structure of a field of knowledge is uneconomical in several deep senses. In the first place, such teaching makes it exceedingly difficult for the student to generalize from what he has learned to what he will encounter later. In the second place, learning that has fallen short of a grasp of general principles has little reward in terms of intellectual excitement…Third, knowledge one has acquired without sufficient structure to tie it together is knowledge that is likely to be forgotten. An unconnected set of facts has a pitiably short half-life in memory. Organizing facts in terms of principles and ideas from which they may be inferred is the only known way of reducing the quick rate of loss of human memory.” (p31-32)
