  1. 1. One in every classroom How colour vision deficiency affects our learners. Caroline Riggs @SciRiggsy
  2. 2. At least one pupil in every classroom sees the world differently. and you don’t know which one it is. and neither do they….
  3. 3. What is Colour Vision Deficiency (CVD)? o Inability to distinguish colours, for example red, green, orange, brown. o 1 in 12 boys and 1 in 200 girls. o Mild to moderate. Of these, 25% are severe. o Not currently recognised as special educational need or disability. o Not routinely tested for in UK, or in many parts of Europe. o By secondary school, less than 50% of children with mild colour blindness are aware of it. o It is estimated that 20 – 30% of severe are unaware that they see the world differently.
  4. 4. What problems could a colour blind pupil have in your lessons?
  5. 5. How can Colour Vision Deficiency (CVD) limit potential? Some examples from the Science Department o Reading litmus paper accurately o Undertaking chemical titrations in practical chemistry exams o Identification of metals by the colour of the flame produced when the metal is burnt o Accurately reading stained slides under a microscope o Carrying out dissections in biology o Identification of species of plants or insects correctly o Fully understanding coloured diagrams in textbooks, particularly in biology o Use of prisms in physics.
  6. 6. Surprise word fill!
  7. 7. How can Colour Vision Deficiency (CVD) limit potential? How can it affect attainment in your subject? o Picking up a red ball from the green floor in PE o Identifying fresh food in DT o Practical activities in Science o Reading graphs and maps
  8. 8. How can it affect behaviour in your classroom? o Copies from others o Makes ‘silly’ mistakes o Inattentive o Lazy o Doesn’t listen properly o Doesn’t try or rushes work o Has poor presentation o Shows frustration o Doesn’t take part o Disruptive o Will assume they are stupid at the subject o May have developed their own strategy e.g. coloured pencils in order/dislike working with others But……..this can vary depending on the classroom/levels of natural light outside.
  9. 9. We have to think things through!
  10. 10. How can we support CDV students? How we are inadvertently making life more difficult: o Use a traffic light system for assessment? o Place pots of mixed unlabelled coloured pencil crayons on tables? o Have coloured labels on library books to indicate different reading levels? o Use games e.g. counting games with coloured counters? o Use worksheets/software which rely on colour? o Use books which highlight familiar sounds using colours? o Highlight teaching points in red and green on the white board? o Colour coded marking
  11. 11. What can I do straight away? Awareness (pupils and staff) Audit learning environments with the app! Label pencils, have a colour buddy Use natural light Use a strong colour contrast (blue is good) Secondary indicators
  12. 12. How are we supporting CDV at Angmering?  Interviews/lesson observations with CVD students.  Identification project with year 7 in Science.  Specsavers eye health screening for year 7 and 9.  Awareness/routine in all classrooms.  Share good practice/feedback to departments. @colourblindorg Apps: CVSimulator
