Supporting Research, Evidence and Argument

Our work in advocating teaching for mastery, and supporting Maths Hubs as they help schools implement it, is largely based on the way maths has been successfully taught in East Asia. The model we advocate is most notably, but not exclusively, exemplified in Shanghai, China.

An exchange programme between teachers from England and Shanghai has informed effective pedagogic strategies for achieving mastery of maths. The striking performances of Shanghai and other East Asian countries in maths have become well-established. They have been measured in successive international tests such as TIMSS and PISA.

For each of the key components of teaching for mastery identified below, we offer a key text. This text is chosen for its relevance and accessibility, both in terms of readability and being able to access it for free online. We also provide a list of further relevant reading. Links in the main text will take you to the suggested key text and further reading. Much of this material features on a reading list for teachers on the Maths Hubs Mastery Specialists programme.

The component thought to be key to the success of the East Asian system is the use of variation theory. Variation theory has several dimensions, including use of multiple representations of what a concept is, and what it is not. It is characterised by a carefully constructed small-step journey through learning. It pays attention to what is kept the same and what changes, in order that pupils might reason. This means that they will make connections and build deep conceptual knowledge. 

Variation is applied to practice questions where attention is paid to the selection and order of the examples. Often just one aspect is changed whilst others are kept the same. The intention is to avoid mechanical repetition but instead to promote thinking to make connections. This is also known as ‘intelligent practice’.

Teaching for mastery is also characterised by a series of beliefs and practices.

Children Succeeding

Mastery is characterised by a belief that, by working hard, all children are capable of succeeding at mathematics. On this basis, children are taught all together as a class and are not split into ‘prior attainment’ groupings.

Carefully structured teaching is planned in small steps. This provides both the necessary scaffold for all to achieve, and the necessary detail and rigour of all aspects of the maths to facilitate deep thinking. The small steps are connected and concepts are built. This leads to generalisation of the maths, and the ability to apply it to multiple contexts and solve problems.

It is expected that those children who will achieve well on a particular topic may not necessarily be the same children who achieved well on other topics. An additional daily short session of 10 to 15 minutes is provided for any pupils who do not fully grasp the lesson content, in order that they 'keep up' with the class. Our experience shows that it is not always the same pupils who require this form of intervention and this boosts the self-belief of previously low-attaining pupils.

Understanding Structures

A focus on exposing the structure of mathematics and developing an understanding of how and why maths works is crucial to mastery. A key skill of the teacher is to be able to represent the maths in ways that provide access and insight for pupils.

Concrete materials, contexts, drawings, diagrams and equations all play a role. These are discussed through opportunities for pupil-pupil and pupil-teacher talk, to develop reasoning, flexibility and adaptability in mathematical thinking.

Learning Facts

Memorisation and repetition of key facts (times tables and number bonds etc.) are important aspects of learning. Evidence from cognitive science research suggests that learning key facts so they can be recalled automatically ‘frees up’ working memory. It can then focus on more complex problem solving, rather than reaching cognitive overload trying to calculate simple operations. In terms of procedural fluency and conceptual understanding, one should not be prioritised over the other. Learning is most effective when the two are fully integrated.

Mathematical Language

Teaching children precise mathematical language and insisting upon its use supports children's ability to think mathematically. Having the language and using it empowers children’s ability to think about the concept.

Teaching for mastery is in the early stages of adoption in England. We will be monitoring research and evidence of its effectiveness and adding to the final section, Recent Evidence.

Kullberg, Angelika, Ulla Runesson Kempe, and Ference Marton. "What is made possible to learn when using the variation theory of learning in teaching mathematics?." ZDM (2017): 1-11. 

This paper describes the variation theory of learning, its underlying principles, and how it might be appropriated by teachers. It is illustrated by an analysis of one teacher’s teaching before and after he participated in three lesson studies based on variation theory.

This article explores Variation Theory drawing on examples from Chinese primary textbooks for the teaching of addition and subtraction of single digit numbers.

Watson, Anne, and John Mason. "Seeing an exercise as a single mathematical object: Using variation to structure sense-making." Mathematical thinking and learning 8.2 (2006): 91-111.

This article looks in depth at use of Variation Theory in written exercises given to learners and explains how exercises written using Variation Theory can support learners in perceiving relationships and structure rather than simply practising a mechanical procedure.

Marton researches more and less successful instances of learning in various collaborations. In this paper, he collaborates with Chinese researchers to ‘unlock the paradox of the Chinese learner’ with variation theory as the key.

Askew provides a readable account of how using Variation Theory can turn mathematics from a set of procedures to a ‘mindful activity’

This research compares the ‘profound understanding of fundamental mathematics’ of teachers in China and the U.S., and how they would use this understanding to inform their teaching. The results demonstrate the deep structural understanding held by Chinese teachers that helps inform their teaching strategies.

Key text 

Willingham, Daniel T. "Is it true that some people just can’t do math?" American Educator 33.4 (2009): 14-19.

This paper offers evidence from cognitive science of cognitive overload. It argues that that learning facts so they can be recalled automatically frees up working memory, so avoids cognitive overload. Willingham also argues that procedural fluency and conceptual understanding should be taught in tandem.

Results suggest that the Chinese students place more emphasis on the role that repetition plays in understanding than their German peers. Full text requires payment.

A guidance report from the Education Endowment Foundation Improving Mathematics in Key Stages 2 & 3 was published in November 2017. It endorses many of the components of teaching for mastery. Links between its recommendations and a teaching for mastery approach are made explicit in this blog by Professor Jeremy Hodgen. Professor Hodgen is Chair of Mathematics Education at the UCL Institute of Education, who led the evidence review.
