Slide 2

Definitions: 1

"Dyslexia may be caused by a combination of phonological, visual and auditory processing deficits, word retrieval and speed of processing may also be present. Every dyslexic person is different and should be treated as an individual."
Adult Dyslexia Organisation (1999)

Slide 3

Definitions: 2

"Dyslexia is a combination of abilities and difficulties which affect the learning process in one or more of reading, spelling and writing. Accompanying weaknesses may also be seen in speed of processing, short term memory, sequencing, auditory and visual perception, spoken language and motor skills."
British Dyslexia Association (2000)

Slide 4

Definitions

"Dyslexia can be identified as distinctive patterns of difficulties, relating to the processing of information, within a continuum from very mild to severe, which result in restrictions in literacy development and discrepancies in performance within the curriculum."
Reid (1998)

Slide 5

B.P.S. Report (1999)

"The evidence base supporting the utility of neurologically-based intervention programs for dyslexia is yet to be established." (pg.29)

Slide 26

Field-Dependent (Global) Learning Style

  • 'Global' Learning is exhibited when students:
    • need to see the whole picture before isolating parts
    • see relationships and often have difficulty with fine distinctions
    • are social
    • want to deal with 'a', 'b' and 'c' together
    • want to have a context in which to fit pieces together
    • believe the 'medium is the message', thus the class atmosphere and a teacher's personality directly affect the learning

Slide 27 to 30

Guidelines for Global Leaners

  • Present learning in a global way:
    • focus on the 'big picture'
    • give an overview & concept
    • Such as:
      • Presenting the overview of a chapter, book or story before specifics
      • Talking through a whole project before starting with step one
      • Starting a new unit by listing 'what we already know'
      • Using big word spaces, so that all the material for a project or topic can be kept out at the same time
  • Make connections among content, integrate learning, identify relationships among subjects
    • Such as:
      • Focusing on patterns, such as word families & number relationships
      • Integrating subjects by organizing curriculum themes and units
      • Using current events & school experiences to teach and practice basic skills
  • Provide a context for learning and a sense of the purpose of the learning
    • Such as:
      • Emphasizing where the lesson is going by outlines and verbal explanations
      • Learning skills in context, such as spelling words from students' own writing
  • Emphazise a positive class climate and helpful relationships with others
    • Such as:
      • Encouraging attention to group work and working with partners
      • Giving frequent praise and external rewards, such as smiles, hugs, pats on the back
      • Attending to non-verbals; 'the medium is the message', including teachers' facial expressions and the seating arrangement in the room

Slide 31

Mind Mapping

  • Generation of ideas
  • Organisation of ideas
  • Useful topics to start with:
    • Plans for the day
    • Plans for the week
    • Memories of a specific event
    • Strategies for a new project
    • Interests & hobbies
    • Highlights of recent book
  • Use of symbols

Slide 32

Mind Mapping

  • Self Direction
  • Self Monitoring
  • Self Assessment

Slide 33

Self Direction

  • What is my goal?
  • What do I want to accomplish?
  • What do I need?
  • What resources do I need?
  • What is my deadline?

Slide 34

Self Monitoring

  • How am I doing?
  • Do I need other resources?
  • What else can I do?

Slide 35

Self Assessment

  • Did I accomplish my goal?
  • Was I efficient?
  • What worked?
  • What did not work?
  • Why did it not work?

Slide 36

Dynamic Assessment

Dynamic Assessment Static Assessment
Monitors how the child learns
Tests what the child knows at that time

Slide 37

Planning

  • poor planners perceive a page in a disorganised manner
  • choose incorrect targets
  • often impulsive
  • make many errors
  • fail to change their strategy if inefficient (Ayers 1995)

Slide 38

Metacognitive Strategies

  • Visual Imagery - discussing and sketching images from text
  • Summary sentences - identify the main ideas in text
  • Webbing - concept maps of the ideas from a text
  • Self- interrogation - ask questions about what they already knew about a topic and what they expected to learn from the new passage

Slide 39

Theoretical Explanations: Implications

  • clear working definition
  • flexible approaches assessment / teaching
  • assessment - school / class based
  • range of provision
  • implications for the authority e.g. Swansea
  • whole staff responsibility - not necessarily specialist
  • training of class and subject teachers
  • initial teacher education input

Slide 40

Implications - Assessment

  • continuous assessment - related to actual curriculum
  • why psychometric assessment? - needs to be diagnostic
  • dynamic / assisted assessment
  • portfolio assessment

Slide 41

Implications - Teaching

  • learning styles
  • aware of learning preferences
  • metacognitive awareness
  • schema
  • study skills
  • mind mapping
  • strategies for different styles
  • importance of classroom environment
  • whole school approaches

'In the Mind's Eye'
T. West

'We ought to begin to pay less attention to getting everyone over the same hill using the same path. We may wish to encourage some to take different routes to the same end. Then we might see good reasons for paying careful attention to their descriptions of what they have found. We may wish to follow them some day'
