A great DI day out at St Martin's

Today I had the enormous privilege to visit St Martin's Voluntary Academy in Stoke Golding. A colleague and I were there to see the use of Connecting Maths Concepts, a Direct Instruction Program that was developed in the United States. I am looking to use these materials to support some pupils who have struggled with maths in the past, and if successful to integrate them into the small group intervention work we do with pupils at my school.

I suspect some will be surprised to hear that from me, particularly after my recent podcast with Craig Barton so allow me to clarify. I am 100% of the opinion that developing understanding of mathematical concepts slowly and carefully is the best way to teach maths, both from a pupil outcome point of view and from a "this is what maths is" point of view. For me, this is what maths teaching should like, and this is what the experience of learning maths should be. So why then would I be looking at a program that (at least on the surface) seems to be entirely about developing "procedural fluency" in isolation? Well for two reasons:

1) I believe that developing understanding carefully and slowly is the best way of going about teaching maths, and that most pupils will develop a strong and flexible understanding of maths by working in this way. But I am not naive enough to think that this will work 100% of the time for 100% of the pupils. It would always be my start point, but for some this will not be enough. We already know that understanding on its own is not enough for retention- pupils forget even those things that in the moment they appear to understand. This is why it is important, even when building understanding of concepts, to plan in opportunities to revisit and re-use ideas. I often refer to this as "picking up an idea", pupils need to pick up ideas they have seen before, play with them for a bit, and then put them down again. And some need a lot more of this revisiting than others. The benefit of this program is that it is at least 80% revisiting previous ideas. And they are built on directly. The links between (for example) adding and subtracting decimals and comparing the sizes of decimals are explicitly made. Couple this with the fact that kids were getting stuff right. Lots of stuff. By some estimates kids in these programs answer up to 500 questions in an hour. And they get the vast majority right. Now I know that maths is not about just "getting it right", but imagine being that kid that only ever got things wrong. That barely even did anything compared to their peers and then mostly got it wrong. Perhaps the only time they got it right was when they had an adult supporting them. Would you be minded to explore the depths of that subject? I know I wouldn't. What I saw today was pupils having the opportunity to be successful in what they saw as maths, something they probably hadn't experienced for the first 6 or 7 years of their education, and then being shown how this can lead them to getting other things right. And I definitely don't think that is a bad thing for eventually supporting pupils to have the productive disposition to explore maths further. Coupled with this is the simple lack of mathematics these pupils have encountered relative to their peers. Whilst the value of "30 million" has been challenged in recent years, it is clear that there is a word gap between disadvantaged pupils and their peers when they start school, and this often widens to the detriment of the eventual outcomes of these pupils. I suspect that part of the power of DI programs is simply the amount of mathematics questions that pupils have to engage with, which will seek to redress any gap in the amount of exposure these pupils have had in relation to their peers.

2) I am far from convinced that these programs have to focus on procedural fluency in isolation. Having worked with Rosenshine's principles of instruction, cognitive science and teaching for mastery principles, I have seen how there is much more to connect them than separate them. Infact this will be part of the subject of my talk at ResearchEd Rugby. It may be that some DI programs do focus exclusively on procedural fluency, but that is not what I saw today. I saw pupils using images of tens frames and larger grids to support their making sense of addition. I saw them making sense of what it means to be a quadrilateral, a triangle, a rectangle, through being exposed to and identifying examples and non-examples. I saw pupils being forced to develop their thinking and language through intelligent questioning, both verbally in the display materials. I saw pupils being expertly guided by their teacher, the fantastic Chloe Sanders who took great care of both myself and my colleague all afternoon.

I would have been happy for the visit to have stopped there, as I had everything I wanted at that point. Instead we were treated to what can only be described as a visit fit for royalty. Firstly treated to lunch with the head, Clive Wright where we had the chance to talk about their journey with DI, discuss the progress of the Knowledge Schools Hub and Chloe's exciting upcoming visit to America to the National Institute for Direct Instruction to talk with (among others) Kurt Engelmann, son of the legendary late Siegfried Engelmann. Then whisked on a tour of the school and seeing the fantastic culture that the team at St Martin's have developed. Every lesson had pupils working with expertly designed materials, taught well by teachers whose expertise were recognised and celebrated, and in classrooms where behaviour was utterly impeccable. A big part of this was the utterly ruthless consistency of application in every classroom. All pupils have access to the same material and challenge, with those who need it supported to achieve as well as others. Every classroom has the same routines, but rather than being stifling to pupils these allow pupils a sense of ease - they know what is expected of them and what they can expect from their teachers. This allows for a relaxed atmosphere where pupils and teachers work together seamlessly for the benefit of all. Everything is thought of and planned, from the lesson materials (not all scripted for DI, but all explicitly taught) to the resealable cans of still water that are available that cut down on plastic waste.

I am honestly not sure I can adequately put into words just how impressive our visit was. My heartfelt thanks have to go to Clive and particularly Chloe who took such good care of us, as well as to all the pupils and staff at St Martin's who accommodated us. I would heartily recommend you visit for yourself if you can and see the incredible work going on at this school - make contact with the Direct Instruction Hub and see it for yourself!

Creating non-standard examples/interweaved examples.

I posed my department a question today in my department meeting:

"Which other areas of maths do pupils need to apply the knowledge that the sum of the angles in a planar triangle is 180 degrees?"

There were some great examples of places such as circle theorems and angles in polygons but also places like coordinate geometry. What we then talked about was the idea of creating non-standard examples from images like those we might find in these area. This led to questions/examples like these:



The beauty of these was that the questions needed very little adaptation to make the focus finding a missing angle in the triangle, and the questions then get pupils used to seeing pictures like this and seeing angles in triangles. Furthermore, if a question can be adapted so that it only requires the angles in a triangle it becomes a non-standard example, but if it can't then it becomes interweaving the other topic into angles in a triangle, or interweaving angles in a triangle into another topic.

We moved the discussion onto other areas as well, so I thought I would share some of the favourite ones that my team came up with:
As part of a lesson about finding area of rectangles, calculate the area of the bars in a histogram. A chance to interleave decimal multiplication. No understanding of what a histogram actually is is required here, but when it is time pupils are already used to looking at them.
Find the area of the shaded triangle. If pupils can solve simultaneous equations then pupils can find the base and height, if not then these could be given to get pupils seeing the triangle. The same stimulus could actually be used at different stages:
1) When first encountering area of triangles with all relevant information given.
2) When solving simultaneous equations in order to find base and height before finding area.
3) When graphing inequalities, which could then lead to the others.

Find the missing angle in the triangle. This was actually adapted from a sine rule question, but could be used in a couple of places before getting to the sine rule:
1) With this information given, just to get pupils ignoring the extraneous information about the sides.
2) Pupils could construct the triangle accurately to find the length x once the angle θ has been found.
