The Maths Horizons report - a response

 For those who weren’t aware, the Maths Horizons project (https://www.mathshorizons.uk/) is a group of educators that have been working to review maths curriculum and assessment in England alongside (but independently of) the governments full curriculum review led by Professor Becky Francis CBE. They have launched a series of consultations in the last few months and have now published a 17 page overview of their findings, including their objectives and recommendations for the next 10 years of maths education in this country.

I think it would be hard for anyone to argue with these objectives – they seem to cover all the main bases including maths for work and daily life, problem solving, and more learners studying post-16. I would be interested to hear of anyone out there in the comments who thinks these don’t cover what a school-level maths education should be for. The recommendations then set out a path for how to meet these objectives over the next 10 years, so let us examine this in a little more detail.

1.      Design a curriculum for mastery

Again, I doubt I would find a teacher of mathematics out there who doesn’t profess to want pupils to master mathematical concepts. The report notes, correctly, that the current design of the curriculum leads to pupils being rushed through content in a “conveyor belt” (in the words of Mark McCourt) curriculum where, regardless of how secure pupils are in their current study, the curriculum pushes them on to the next “unit” with no time to support and correct those that fall a little behind. As such gaps widen over time, leading to the current state that between age 5 and age 16 relatively small gaps in children’s prior knowledge become so wide that some pupils can achieve nearly 240 marks on a higher tier paper, whilst others can barely score 20 on a foundation paper. The report highlights that in countries like Singapore, there is much less breadth and much more depth during early number work, ensuring that the foundations for future learning are well secure. In working with my trainee teachers this year, I have several times highlighted that learning about a mathematical idea looks more much like this:

and that if we don’t give enough time in that slow-burn phase of development, we won’t see that rapid take off in later learning. The knowledge progression maps that this recommendation suggests be created in the report need to specify this clearly, including providing the necessary time for depth in early phases, and how this should lead to more rapid gains later. This is more work than it sounds though, as a lot of the knowledge contains in the National Curriculum is not well sequenced or specified; one example is the idea of gradient, which is only mentioned once in the KS3 National Curriculum alongside graphs and interpreting gradients of graphs. However, gradients are an idea in of themselves, having much more affinity with compound measures and rates of change before being tied to linear graphs. This needs stripping out and tackling separately before being used with linear graphs. There are other examples of this in the national curriculum that will need to be identified and dealt with before these progression maps can be built.

2.        Rebalancing content from upper primary to lower secondary

I applaud this statement; it is one that I have long called for myself. The primary curriculum is woefully overloaded, meaning teachers often have no choice but to accelerate through content in order to ensure that it is all “covered” by the time that SATs role around this week. I also applaud the notion that, broadly speaking, the content of the National Curriculum as a whole is fit for purpose, and comparable with other countries. The report also highlights that a lot of the content at primary school is also taught (either by necessity or design) during secondary school. Indeed, the late, great Dr Tony Gardiner even suggested a list of this in his epic book “Teaching Mathematics at Secondary Level” (which is 100% worth reading if you haven’t and, hopefully, will be called on heavily by the members of the Maths Horizons project):

·        the extension of place value to decimals;

·        the arithmetic of decimals;

·        work with measures—especially compound measures;

·        the arithmetic of fractions;

·        ratio and proportion;

·        the use of negative numbers;

·        work with coordinates in all four quadrants;

I am sure that there are many secondary teachers of maths out there that will recognise and agree with these concepts as serious issues for many pupils progressing from primary school, and that these topics for a lot of the early work that secondary school mathematics departments have to do before pupils can progress further in their mathematics. I do thank that some of these could come off the list (particularly negative numbers and coordinates) if space were made to deal with the properly at primary school whilst shifting some of the others completely into secondary school.

What I am disappointed to note in the Maths Horizons report, however, is the lack of recognition of a need to further rebalance some of the lower secondary curriculum content from KS3 into KS4. The same issues arise here, with content taught at KS3 also having to be taught at KS4, and the rebalancing of KS2 content into KS3 will only serve to push the problem into secondary schools, where content will have to be rushed in order to meet the demands of KS3. A similar list of content that could simply be left to KS4, whilst KS3 can focus on developing and deepening the pre-requisite maths so that more rapid progress can be made at KS4 might include:

·        Significant figures (both the concept and rounding to them) – to understand this properly takes a depth of appreciation of the place value system, its invariant properties and the role(s) that 0 plays in the system.

·        Expressing errors as inequalities – this requires a more flexible knowledge of the use of inequalities, and the difference between discrete and continuous measures (as well as treating numbers in both discrete and continuous fashion) than most pupils can achieve at KS3.

·        Rearranging formulae to change the subject – this seems to be included so that other concepts can be included (which could themselves be moved to KS4). Rearrangement requires a depth of knowledge of equality, and valid manipulations of an equality relationship, that only really begins to develop using algebraic symbology at KS3. Whilst I am in favour of learners manipulating all types of equations at KS3, I think the requirement to do this with a specific goal in mind such as changing the subject can be left until KS4 to allow the pre-requisite knowledge to mature. It is worth noting as well that the skills build heavily on equation solving skills (which I would keep at KS3) and so moving rearranging formulae to KS4 would provide a good opportunity to revisit and develop these skills in a new context.

·        Reducing a linear equation in two variables to the form y = mx + c – this is tied to the previous point. Whilst the relationship between algebraic relationships and their graphical representations definitely does need to begin to be explored at KS3, the need to combine all of this knowledge and skills can be left until KS4 when the knowledge of the separate concepts that come together to make this viable has matured.

·        Graphical and algebraic representations of proportion and inverse proportion – beyond the basic graphical representations of proportional relationships like conversion graphs, I feel that the movement from proportional representations like Cuisenaire rods™, double-number lines and ratio tables to more abstract algebraic representations can wait until KS4, where both algebraic and proportional understanding can be made more mature.

·        Ruler and compass constructions – done well, these need to be tied directly to properties of shapes, congruence/similarity and other graphical representations (including graphing inequalities in two-dimensions). As such, I think these can be left to KS4 alongside some of these other concepts.

·        Applying transformations to given figures – Again, if done properly these need to be tied to a basic understanding of vectors (which I would welcome at KS3 as they are a natural extension of using a vector representation in one dimension for negative numbers). I also take issue with the focus on given figures; transformations happen to every point in the plane (accepting certain invariant points) and so the focus on plane figures as opposed to individual points is misleading.

·        Identifying and constructing congruent triangles – Whilst I think the basic idea of congruence as a property of shapes can be introduced at KS3, the necessary conditions for congruence at triangles can probably be left to KS4 in favour of other things.

·        Introducing/deriving Pythagoras Theorem – Whilst, again, Pythagoras Theorem as a property of right-angled triangles could be introduced to KS3, it is too often simply as a vehicle for forming and solving equations which would be better placed as an opportunity to revisit these skills at KS4.

·        Use Pythagoras’ Theorem and trigonometric ratios to solve problems – as above for Pythagoras, but trigonometry in particular requires a depth of understanding of similarity, invariance, functionality and equation solving which should be the focus at KS3 so it can be used for trigonometry in KS4.

Again, I know all of this is re-taught at KS4 even when it is taught at KS3 (under the mistaken belief that a GCSE specification sets out the knowledge that needs to be taught in two years rather than 11), so I think we can shift this to KS4, making room for the concepts that will be moved up from KS3 and allowing more time to secure the fundamental pre-requisites of some of these concepts.

3.      Increase the rigour of mathematical reasoning and problem solving for all students

Again, I am pleased to see in the report that proof, reasoning and problem solving should be at the heart of how mathematics should be taught, rather than as a bolt-on that is taught after pupils have been taught some procedural maths. In my session at the La Salle Education Complete Mathematics Conference in March I talked about the relationship between fluency, reasoning and problem solving, where I shared this diagram as much more indicative of their interplay:

As part of the recommendation, the report suggests “creating examples and questions that demonstrate which “familiar content” should be developed through problem solving, and which types of problem to use.” My internal jury is out on this part; I think I would need to see in practice what this looked like. As read, it seems to suggest that certain content should be taught through problem solving, and different content not. This is not in line with the diagram I shared above. Rather the examples and guidance needs to show how each and every concept in maths arises reasonably (by which I mean “by means of reasoning”) and that this development allows us access to new questions and problems that we can ask and answer. For example, when we extend numbers beyond the naturals into the full integers (i.e. to include negatives) it then becomes perfectly natural to ask “how do our four basic operations behave with these types of numbers?” This can then be reasoned out based on our understanding of the properties of these operations and the models we use for them. Note, I am not saying that pupils should be left to reason all of this for themselves; teachers will need to take a range of strategies between reminding, prompting and explicitly teaching the reasoning that allows us to make sense of how to combine the previously studied operations with these new types of numbers. If this is what the recommendation becomes, then I welcome it.

 

4.      Introduce low-stakes gateway checks of fundamental knowledge

This is the first recommendation that I am almost certainly flat-out against, primarily because I cannot see how it is compatible with recommendations 1 and 2. In a true mastery curriculum, time is the ultimate variable. It is a simple fact that some pupils will take longer to achieve the depth of knowledge required, and if we are going to push for all pupils to do this, we will need to give some more time than others. Implementing a knowledge check at certain arbitrary points in the learning journey (such as near the end of certain school years), will have the opposite effect to that proposed in recommendation 1 – rather than teaching for mastery it will push teachers to try and rush pupils to this point. Even in a low-stakes environment (i.e. without the fear of accountability measures), setting a check at a certain point will communicate to teachers and leaders that pupils are expected to be at a certain point by a certain time. Planning will then take this into account, with curricula built to ensure that this happens, with kids pushed through the curriculum to get to the expected point. The report highlights the Multiplication Tables Check in year 4 as an example of such a check (although does recommend reviewing the impact of having the questions timed and reporting the results). Now, aside from the fact that the multiplication check doesn’t at all check that pupils really understand multiplication (it only tests that they can parrot out certain multiplication “facts”), it also sets in stone the idea that by this age, all pupils should be at a certain point in their learning journey for multiplication, which may or may not be true.

The only way I can get on board with something like this is if schools can choose when individual pupils can sit such “checks”, in order for it to truly be a check of whether a pupil has mastered the knowledge necessary to move forward with the curriculum.

 

5.      Reform the Key Stage 2 SAT exams

Another recommendation to be broadly applauded, particularly the part that recognises that the “expected standard” can be reached by securing less than half marks, which doesn’t really help secondary schools build on what pupils’ study at primary with any real security. Given that pupils can secure over a third of their marks on the arithmetic paper alone (the report highlights that many schools will cram the arithmetic paper material for exactly that reason), a change in the structure of the papers to integrate the reasoning and problem solving with the arithmetic, and a change to what is needed to secure the expected standard is probably long overdue. The only bit I am unsure of here is that, as part of this recommendation, Maths Horizons have suggested raising the marks required for the expected standard from 50% to 75%. I am not sure where this figure of 75% has come from though? There doesn’t appear to be anything in the literature that suggests that 75% is a good benchmark to aim for to evaluate mastery. The lowest figure I have seen quoted is 80%, which I think if we are going to strip down the content would be a better figure to decide if a pupil has mastered the foundational content present in the primary curriculum.

 

6.      Reform the GCSE Exams

Again, another recommendation that seems sensible. The report highlights that, similarly to the KS2 SATs, the benchmark for achieving a level 2 qualification in maths (GCSE grades 4 or above) is probably too low. The report talks about the introduction of a “gateway” paper that all pupils sit with a high threshold to achieve a “standard pass”. It is unclear what pupils would do after this though, as the report also rejects suggestions to split the GCSE into “methods” and “applications” (as trialled in the Linked Pair Pilot back in 2010 – still a great source of exam style questions though), or to implement the “numeracy” and “mathematics” split that Wales did in 2015. A big reason for the rejection was the “social sorting” that happened where some pupils were only given access to one paper, limiting their chances, and that universities typically ignored the “numeracy” paper (in the Wales approach). It is difficult to see how the gateway paper would be treated differently if it were followed with either optional or compulsory further papers. It also seems, at least on the surface, difficult to make a high threshold for the gateway sit alongside the previous year’s performance without making the content very low; how would a standard pass in the year 2030 compare to a standard pass in the year 2020? Interestingly, the language used is exclusively “standard pass” rather than “grade 4”, suggesting that maybe the grading system might change under this proposal. However, this still seems to make it difficult not to disadvantage the first few years of a cohort that might sit these reformed GCSEs, who would have to do more to get a standard pass than previous years.

 

7.      Explore a maths entitlement for 16- to 19-year-olds

Honestly, I am struggling to see what this recommendation adds to the whole project. It seems to be a lot of “continue what you are doing”. Promoting Core Maths is mentioned, alongside building capacity so that it can be offered in more places. This will bump into the age-old problem of there not being enough teachers of maths to offer this more widely, and not enough pupils wanting to take it up. Reviewing the A-Level content is fine, but generally speaking the A-Level has a good balance of core and applied elements so unless we went back to optional applied modules, where students could pick whether to study statistics or mechanics applied modules, I think the best this can achieve is tweaking around the edges. The idea of a stand-alone A-Level Further Maths qualification is potentially interesting, but difficult to see how it would work practically without duplicating a lot of the work that students complete as part of the normal A-Level qualification, and so would likely lessen the scope of what is achievable compared to the current model of the Further Maths A-Level sitting on top of the A-Level Maths, with students needing to study A-Level Maths in order to also study A-Level Further Maths. A potentially more useful avenue is to widen access to the current Further Maths A-Level; but on the whole this recommendation needs to be more fleshed out to before we can see its merits.

 

So, that is my take on the latest Maths Horizon Report. Let me know what you think about the report, or my response, in the comments.

Maps and Maths

Wow, it has been a while since I have written anything other than posts to link sessions to, but I had something in my head today which I just had to write about.

Recently Ofsted have produced a report, "Coordinating mathematical success" where they outline what their inspections have found about what maths teachers are doing well, and not so well. The Association of Teachers of Mathematics (of which I am a member just to make sure any biases are public) have written a response to this which I think is very balanced - supportive in some areas and rightly critical in other. There is one section of this response to highlight:

"It is of course possible to create a journey of ‘small steps’ with the hope that these steps become connected, but we challenge the prominence of these small steps in the report. When undertaking a journey, the primary focus shouldn’t be on each step but rather on an awareness of the landscape and the multiple possibilities within it. "

I have seen these arguments before and also seen people before liken this to a map - with some advocating providing a map of the journey through mathematics, with strict adherence to the planned route and a focus on each "step" of the journey and where it takes us (the "small steps" indicated above), whilst others advocate for just getting out there and exploring, creating our own sense of where things are in the landscape, and looking out for interesting landmarks to go and see. 

The reason this came to mind is that today I was travelling to the lovely High School Leckhampton in Cheltenham to work with the GLOW Maths Hub LLME community on using Cuisenaire rods. As it was a nice day I decided to walk the (little over half an hour) journey from Cheltenham Spa train station to the school. On my way, I used Google Maps walking feature in the way I often do, which is to get it to show me the journey, but not to start the navigation so that I can retain an overview of the whole trip and my progress on it. Now, of course, there is plenty of analogy already there in terms of making sure that pupils retain a sense of the journey and where they are within it, but it wasn't this that prompted my reflection. What did prompt my reflection were three incidents along the journey:

1) I took a wrong turn at a place where the map wasn't complete. I was supposed to follow a footpath that appeared to be the only way I could go on the map. However, when I actually arrived there was a smaller path (that turned out to be the path I should be taking) and a larger path (which I assumed would be the one I would take). I walked for about a minute down this larger path before glancing at my phone and realising that I wasn't following the path laid out for me, and that the path that I was following didn't appear to be marked on the map. Could I have got from where I actually was back on course? Perhaps, but not being familiar with the area I didn't know this (or know how) and so I back tracked the way I had come to get back on the correct path. This cost me a small amount of time, but fortunately I had factored extra time into my journey.

2) A little later I came out of the correct path onto a road on which I was supposed to turn left and follow around an arc to continue my journey when I noticed that, across the road, a new path seemed to continue on in the direction I was headed, potentially cutting out the arc. This path was also absent from the map. In that moment I faced a choice - follow the route as programmed or divert off on this path which I was fairly sure was going in the right direction, and possibly quicker than the route shown on the map, However, I couldn't guarantee that this was the case, that the path wouldn't veer off and take me in an unwanted direction. I made the choice that I suspect quite a few people would make which was to forgo the new path and continue on the route laid out. When I got around the bend a little later, I noticed that there was a path exiting onto the road again, and noted that this was likely the path I had noticed before.

3) On my way back from the school to the station, I didn't really need my map. I had it on, as a safety net, and my have glanced at it once or twice, but I didn't need it to tell me all of the twists and turns I needed to take - I knew the way I had come and was quite comfortable back-tracking along that route. Except I didn't really back-track along that route. I was able to adapt it to make it more comfortable for me. This time I did take the path I alluded to in point 2, and it was indeed quicker than following the road around. I had also noticed on my journey to the school that the small path I had come down in point 1, was connected back to the road I had walked down before joining it at a point further along the road, and that I could probably save myself an uncomfortable and a little muddy walk by cutting out onto the road earlier when I was coming back. So I did that (and this is one of the points where I did glance at the map again to confirm that this would be an acceptable alternative.

Why did this prompt me to think about maths teaching/curriculum (as if the reader couldn't guess!)? Well it suggested to me a few things:

1) The map was ultimately important. Because I was under a time pressure going in both directions (one to get to the session on time, and one to get to my return train on time), I likely wouldn't have got to where I needed to be when I needed to be without the map. Given that school level maths has its own time pressures built in, I think the idea of having the map and a planned journey within it is important, which translates directly to a well-sequenced curriculum that takes learners on a journey.

2) The usefulness of the map, and sticking more rigidly to the planned route on the way to the school was, in part, down to the fact that it allowed me see places where, on my return journey, I could perhaps be a little more flexible. As I mentioned, I didn't use the step by step navigation because I like to retain the overview but I wonder if I had, whether I would have noticed those same places where I could adapt the route as I did in point 3 above. I wonder about whether we are doing a disservice to pupils in situations where we take them through very small steps, particularly for those pupils (like me) who would get frustrated if they couldn't see where that step fell in the journey, and also if this deprives all pupils of the opportunity to notice places where they could take an alternative. However, this is linked to the next reflection/suggestion...

3) It was only because I had followed the route provided on the way there that I felt comfortable making adaptations when I followed the route in reverse. I don't think, it is the reverse thing here that is important - I think it was familiarity with the journey between the two. I feel like I could walk a very similar route again from the station to the school without the map, or only having to reference it occasionally rather than follow it completely (at least whilst it is fresh in my memory). But it was only the familiarity I gained that has given me this confidence. Now I am sure that I could eventually get the same confidence if I took the time to stroll around the space between the two venues, but that time wasn't available to me given the aforementioned time pressures. I also think that the map is useful to help with my explorations were I to have the time to explore, which leads to the next point...

4) The route I took wasn't the only route I could have taken. When I first put my destination into Google Maps, it offered me three possible routes to complete that journey. Being able to look at the map suggested several others (mainly slight deviations or possible shortcuts based on the three main routes). On the route I followed I saw several landmarks - a church, a Texaco garage, street names etc. that were useful checks that I had for when I made the return trip and would be useful were I to make the trip again. But there were lots of things I didn't see because of the route I chose. Some of those things may have been more interesting than the church or the garage. I suspect had I taken a more westerly route my views would have been better (judging by the glimpses of the countryside I saw in that direction whilst following the route I did, and my subsequent scrolling of Google Maps to see what might lie in that direction). 

So what do I take away from all of this?

1) A planned sequence is ultimately useful, but having the step by step navigation would perhaps draw attention away from the journey itself, frustrate those that need to see how their progress fits into the journey as a whole, and might mean those following the journey miss some things that could build their confidence in being adaptable when encountering the same or similar content in the future - so part of our job is making sure that they don't miss these things and that they have the opportunity to recognise the important aspects of the landscape.

2) No route or map is perfect, no matter how expert the map maker/route planner, so it is important to build in time to allow for the occasional wrong turn, even with those who are generally quite good at following the journey - a new journey is still a new journey.

3) For some at least, the confidence to explore and adapt will be enhanced by the security of "the map", the pre-existing knowledge of the landscape that can be accessed, and knowing that they are never too far away from a familiar space.

4) We must build in time for that exploration and adaptation once the map is laid out - if we are only ever moving onto a new journey with every step then, for most, the only thing they will feel like they can do is follow the route exactly.

5) When we plan a journey through a curriculum for pupils there will always be different competing considerations - time, which route allows the "best" experiences, the attitudes of the learners towards possible wrong turns or deviations etc. and we need to evaluate our chosen journey to look at what we sacrifice as much as what we gain.

Of course, the big difference in this scenario is the pupils can't really "see" the map until they have experienced it. I was able to call up a map that someone else had created, but in learning mathematics the "map" exists inside everybody's head, I have my map, you have yours. Learners create their own maps when we take them on a journey through a mathematical idea, and whilst we can communicate something about what that journey looks like, it only becomes real once experienced - I can't simply transfer my "map" into my pupils' heads. I think this reinforces point 4 above about building in time for exploration in areas that pupils have already travelled, revisiting ideas not just to see if they can remember the exact same journey as before, but to give them chances to take shortcuts, amend the route, or explore the consequences of going off on a new path.

My final thought is that I wonder how much of this is specific to maths? It seems like a lot of it might apply to many subject areas but, not being overly familiar with many of their maps, I cannot say for sure.
