Agenda
- Dyslexia
- Dyscalculia
- Research
- Memory problems
- Anxiety
Slide 3
What is Dyslexia?
- Dyslexia is evident when accurate and fluent reading and/or spelling develop very incompletely or with great difficulty. This may be accompanied by a difficulty with numeracy.
Slide 4
Memory and Organisation
- Remembering -alphabet -tables
- Copying correctly
- Forgetting instructions
- Remembering formulae
- Coping with time
- Learning it one day - then...
Slide 5
Prevalence of Dyslexia
- Roughly 10% dyslexic
- 6% moderately
- 4% severely
- 4% to 25% will either be dyslexic or have dyslexic difficulties
Slide 6
The Bangor Dyslexia Test
- This is a quick way to identify dyslexia
- Looks at 10 areas of difficulty
Slide 7
Family History and Developmental background
- Dyslexia is hereditary
- Delay of early development
- Usually blood relatives with difficulties
- Some birth difficulties
Slide 8
Characteristics of Dyslexia
- Discrepancy - intelligence and attainment
- Good and bad days
- A spiky profile
- Problems
- Disorganised
- Poor results
Slide 9
Other Dyslexia Difficulties
- Reading
- Spelling
- Writing
- Sentence structure
- Sequences
- Avoidance strategies
Slide 10
Visual Difficulties
- Eye tiredness
- Letters - move
- Glaring white spaces
- Skipping words
- Scotopic sensitivity syndrome
Slide 11
Behaviour and Emotion
- Reading aloud
- Tiredness - effort to achieve
- Low self - esteem
- Frustration
- Peer group rejection
Slide 12
Definition of Dyscalculia (Butterworth 2002)
- Number blindness
- Number concepts
- Learning number facts and sequences
- Mechanical procedures
- 6% calculation - 4% reading
Slide 13
Dyscalculia (Kosc)
- Verbal (interpretation of terms)
- Operational (performing operations)
- Lexical (written terms, symbols)
- Graphical (symbol manipulation)
- Ideognostic (mental calculations)
- Practognostic (pictorial representation)
Slide 14
Thomas West (In the Mind's Eye)
- For Dyslexics 'hard' things can be easy and 'easy' things can be hard
- Paradoxically in school before achieving 'hard' things you must be good with 'easy' things
- Some dyslexics leap forward with certain concepts, without systematically going through all the 'proper' steps
- Older students concentrate on areas of strength
Slide 15
Types of mathematical deficits (Luria)
- Deficits of logic: problems with spatial order e.g. 'the circle below the square', or writing numbers in correct sequence.
- Deficits in planning: developing problem solving strategies - understanding the maths language.
- Perseveration: inflexibility in application e.g. continuing to divide by 2, a strategy which has been successful.
- Inability to do simple calculations: e.g. use of multiplication tables, inefficient counting or addition strategies.
Slide 16
Students may have problems with all or some of these:
- Language of mathematics
- Visual, direction, sequencing
- Organisation
- Memory
- Poor short-term memory
- Filing system in long-term memory
Slide 17
Maths Checklist can they:
- say times tables correctly?
- do simple computation?
- say what the symbols mean?
- identify shapes?
- count forwards and backwards?
- copy numbers correctly?
- say the days of the week, months in order?
- tell the time, use money?
- read and write numbers?
- do mental calculations, work out sequences?
Slide 18
Importance of understanding poor concentration skills
- Students yawn, cannot sit still and appear bored
- Functioning becomes erratic
- Important pieces of information
- Have 'time out'
- Slow processing hinders learning
Slide 19
Memory problems
- Verbal instructions
- Writing on the board
- Personal belongings lost
- Remembering where things are kept
- Learns it one day - forgets it the next
- Many intelligent people have problems remembering and that memory is like a muscle the more it is used the stronger it becomes
Slide 20 - 21
Memory and Mathematics
![]() |
- Short-term memory
- Active-working memory
- Visualisation in AWM
- Improvement of AWM
- Long-term memory
- Oral recapping
- Transfer strategies
Slide 22
Helping short-term memory difficulties
- Emphasise important information
- Multi-sensory teaching is vital
- Rote memory - provides limited understanding
- Close collaboration is essential
Slide 23
Active working memory (AWM)
- AWM is a half way house
- Lose track
- Forget one part of a calculation
- Forget what has just been read
- Unable to develop a strategy
- Impulsivity
Slide 24
Problems with Long Term Memory (LTM)
Permanent memory- information needs categorisation
- New rules
- Slow processing - partial facts remembered
- Discussions nightmare
- Failure in examinations
- Complex patterns
- Information overload
- Long sequences
- Speed
- Long holidays
Slide 25
Some other issues
- Dyslexics are slower
- Speed working a disadvantage
- Error patterns
- Avoidance
Slide 26
Fear in Maths
- Cockcroft Inquiry said, "...there was widespread reluctance to be interviewed, more than half of the people approached initially refused to participate."
- Many said that they had never understood 'The Proper Method'
- Individuals successful in their own field
Slide 27
Causes of Anxiety
- Low self-esteem
- Difficulty with language
- Work is too hard
- Preciseness
- Inability to make a start
- Times-tables
- Self management
- Distractions
- Teacher / Relationship / Attitude
Slide 28
Anxiety (A simplistic look at the brain)
- Reptilian brain -survival skills
- Mammalian brain deals with:
- health: heart rate, blood pressure, metabolism
- emotions: joy, sorrow, anger
- learning: linked to memory
- Neo-cortex controls the highest level of thinking like mathematics & scientific experiments
Slide 29
How to Help with Anxiety
- Relaxation techniques
- Focus on success
- Rituals & routines (start and end of lessons)
- Regular positive feedback
- Set realistic goals
