This course is for teachers to learn why some children have so much difficulty with reading and writing, often called 'dyslexia', and to learn more about best practice in teaching literacy to all in light of recent scientific discoveries.

'Co-morbidity', and psychological and social aspects
The ‘dys’-constellation (dyspraxia, dyscalculia etc); audition; vision; loss of self-esteem; long-term effects of school drop-out and antisocial behaviour – evidence from Canada; ‘positive’ aspects of dyslexia and unusual aptitudes; discussion around pros and cons of ‘labelling’ a child

So another part of the wider dyslexia constellation
can be issues with maths or math.
And research suggests that up to 60% of children with dyslexia
do experience some kind of issues with maths.
What we find here, again, as with all of these aspects of the constellation,
we can unpack them and their complex constructs in their own right.
And obviously the same with maths.
Maths actually represents many different skills to acquire.
But we can, from the knowledge you've already gleaned from this course,
we can actually make now connections to how that might impact maths ability.
What we typically see is that for students with dyslexia,
they can often have strengths in the more spatial aspects of maths,
so for example geometry and things that involve spatial representations.
And this is certainly an area where some individuals with dyslexia
can show real strengths in relation to their typically reading peers.
And often they can be actively recruited into professions
that value these types of skills.
But then in terms of challenges, there's lots of language
in phonology in math, which can be a hurdle sometimes.
And so if we think about the early stages of learning maths,
dependent on the approach, of course, but
in many traditional ways of teaching, there's quite a lot of rote
memorization in some of the basic rules, (and multiplication tables.
And so this rote memorization and reliance on both short-term memory and
working memory, we can kind of predict that this might be tricky for
someone with dyslexia, because these are vulnerability areas for them.
And this is what we see.
We see where facts are expected to be learned by rote
children with dyslexia can really struggle.
So then they don't have the foundations
upon which to build some of the more complex processes.
We also see that we've talked about how dyslexia
can result in issues with sequencing.
And lots of mathematical operations involve a good sense of sequencing.
So you need to be able to carry out multi-step operations.
But then, also, sometimes things are more complex in terms of having to reverse
the order of things in part of an operation to get to the ultimate answer.
So your sequencing skills need to be really strong for
many aspects of maths, and so again, this can be a challenge for
some people with dyslexia, if not presented in the right way.
Where we're talking here, actually,
teaching that helps children get, dig down to the concepts, so they're not having to
rely on memorized facts for maths, can really succeed.
It's not that the conceptual understanding isn't there, but
sometimes the way of teaching and the layers of language and
sequencing can make it hard to get down to those core concepts.
There can also be difficulties distinguishing between similar types of
symbols, so for example the addition symbol and the multiplication
symbol can look quite similar, as can the subtraction and division symbols.
So, choosing the type of operation can sometimes trip people up,
as well as if you start thinking about word problems in math,
there's all sorts of different words for operations that we bring in.
So, for example, with even a subtraction, we can talk about subtracting,
taking away, there's going to be a difference between numbers,
lots of abstract relational terms,
sometimes often meaning similar but slightly different things.
And so this is often a big trip-up for people trying to find out
what concepts they're being required to do within this mass of abstract words.
And so again, teaching approaches that help teach the concepts without this,
sometimes students are going to have to learn to navigate this to get
through certain mandated exams.
But you can give them the confidence in maths by helping them
get the basic concepts, ... ... ... ... ...
maths is something where it's particularly easy to develop an anxiety or
a feeling of lack of competence.
So you really do want to try and instill that competence in the early years.
We can get even more, a bit more philosophical here as well when we
actually link to what we were talking about in (week) one about writing systems.
So often it's asked why some of the Asian countries are much stronger in mathematics
than, for example, European countries, And one thing people sometimes mention is,
well the language of their number system is just much more transparent then ours
which may help with some of the processing.
So to give an example of the somewhat lack of transparency in English.
If you think about, if we take say the teens.
So we've got 13, 14.
If we think about how transparent the numerical quality of those terms is,
we can tell, well especially with 14,
we can tell there's something about a four there.
And then if we know there's 13, 14, 15 we can extrapolate
the teen is something to do with the teen numbers.
But 13 is not completely transparent.
We've got to link the 'thir' to a three.
But then if we think about 11 and 12, if you see those written out,
where's the clue to actually what the numerical properties are there?
So, at the moment, we're still trying to work out how much of a hindrance this is,
and it's not going to be the whole factor, but it is an interesting reflection on
how actually certain languages may just give children a head start and
make certain things slightly easier, especially if phonology and
language are issues for you.
So this is just a taster of some of the interaction between maths and
reading difficulties.

talks that you can look at on his website, and
