- 1. One in every classroom How colour vision deficiency affects our learners. Caroline Riggs @SciRiggsy
- 3. At least one pupil in every classroom sees the world differently. and you don’t know which one it is. and neither do they….
- 5. 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.
- 6. What problems could a colour blind pupil have in your lessons?
- 7. 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.
- 14. 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
- 15. 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.
- 16. We have to think things through!
- 17. 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
- 18. 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
- 19. 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. http://www.colourblindawareness.org/ @colourblindorg Apps: CVSimulator
