Transcript

  • 1. by the Cookie Cloud Team A Scientifically Validated App to Help Children to Overcome Dyslexia in Spanish
  • 2. Dyslexia • Dyslexia is a learning disability characterized by difficulties with accurate word recognition and by poor spelling and decoding abilities ! • As side effect, this impedes the growth of vocabulary and background knowledge • Children with dyslexia tend to show signs of depression and low self-esteem (Vellutino et al., 2004) (International Association of Dyslexia, 2011)
  • 3. Dyslexia (Jiménez et al. 2009) (Paulesu et al. 2001) (Eurostat, 2012) (Interagency Commission on Learning Disabilities, 1987) • Neurological origin ! • 7.5-11% Spanish speaking • 50 million in the European Union • 10-17.5% of the US population • Frequent • Universal (Shaywitz, 2008)
  • 4. Dyslexia and Education • Today, the most frequent way to detect a child with dyslexia is due to her or his academic failure • In Europe 15.2% of the students do not finish the obligatory secondary school • In Spain 31% of the students drop secondary school • In Spain 4 out of 6 cases of academic failure are related to dyslexia (International Dyslexia Association, 2011) ! (European Commission, 2011) ! (Eurostat, 2011) ! (Federación Española de la Dislexia, 2008)
  • 5. Traditional Methods for Overcoming Dyslexia • To mitigate dyslexia, children need to do language exercises • Paper based • Monotonous exercises • Dyslexia workbooks are boring for children
  • 6. The Idea • Provide children an interactive and engaging tool • Overcome difficulties while playing exercises created with a new linguistic based methodology
  • 7. since March 2011
  • 8. Luz Rello Linguist, PhD 
 student 
 on dyslexia Clara Bayarri Software Engineer Content Design & Evaluation Development Graphic Design The Team Azuki Gorriz Graphic Designer 
 and Illustrator
  • 9. Features • Exercises in Spanish and English • More than 5,000 different exercises • Six types of exercises • Five difficulty levels: initial, easy, medium, hard and expert • Graphics showing the learning evolution • Engaging elements: points, sounds and accessories to customize your penguin (app’s pet)
  • 10. New Methodology
  • 11. Scientific Content Design (Rello,Baeza- Yates, Saggion & Pedler, LREC 2012) (Rello, & Llisterri, LDW 2012) (Rello, Bayarri & Gorriz, ASSETS 2012) • Creation of a corpus of texts written by children with dyslexia • Linguistic analysis of the errors • Integration of the linguistic patterns in the exercises
  • 12. Exercise Design • Phonology • Orthography • Morphology • Lexicon Empirical Error Analysis 
 + Difficulties • Omission ! ! • Substitution
  • 13. • Insertion • Derivation • Word Separation • Transposition
  • 14. Difficulty Levels • Defined by: • Specific difficulties of 
 Dyslexia 
 • User testing (15 participants) (Rello, Bayarri & Gorriz, ASSETS 2013) • Word length • Frequency • Number of neighbors
  • 15. Text Appearance • Based on previous research on people with dyslexia using eye-tracking (Rello, Kanvinde & Baeza-Yates, W4A 2012) (Rello & Baeza-Yates, ASSETS 2013) • Best fonts for dyslexia ! ! • Good colors for dyslexia
  • 16. Engaging Children • The penguin grows and earns prizes (Rello, Bayarri, & Gorriz, TISE 2013)
  • 17. For Parents & Teachers • Graphics showing the evolution of the child (Rello, Bayarri, & Gorriz, TISE 2013)
  • 18. Scientific Evaluation • Longitudinal study in Lestonnac School, 
 with psychologists from Creix Centre • 8 weeks (April-June 2013) ! • 48 participants 
 with dyslexia • From 6 to 11 years old [Rello et al., ASSETS 2014]
  • 19. Methodology Design within-subjects Independent measures Piruletras Word Search Dependent measures Writing — Rate of Words with Errors
 Writing — Rate of Errors per Word Writing — Rate of Errors per Wrong Word
 Reading — Rate of Errors per Word Subjective Reading and Writing Skills Procedure It is a contest! Materials TALE tests ! Reading and Writing Tests - Test Structure - Word Content (children’s school textbooks, app words) - Age Groups [Rello et al., ASSETS 2014]
  • 20. Methodology • Participants - 54 potential participants - ‘Test of Reading and Writing Analysis‘ 
 (TALE) to diagnose dyslexia - 48 participants (29 girls and 19 boys) - All experienced in playing computer games 
 - 44 of them regularly played games on 
 mobile devices Two Groups using TALE Older children: 16 girls and 8 boys 9 to 11 years old
 fourth and fifth year (µ= 9.92, s = 0.78) Younger children: 13 girls and 11 boys 6 to 9 years old 
 first, second and third year 
 (µ ̄= 7.67, s = 1.00) [Rello et al., ASSETS 2014]
  • 21. Results Older Group Younger Group [Rello et al., ASSETS 2014]
  • 22. Conclusions • It significantly improves the writing of children with dyslexia (9 and 11 years old after 4 weeks) • 42% less writing errors • 34% less errors rate per wrong word hace = 0 error
 ace = 1 error
 aze = 2 errors [Rello et al., ASSETS 2014]
  • 23. Social Impact • 17,000 downloads 
 (Since June 2012) • More than 70 countries • Since September 2013: 
 — 2,282 downloads 
 — 310 sold (0.79€)
  • 24. Social Impact • In the curriculum of specialized centers in Barcelona and Balearic Islands: Creix, UDITTA, Coddia, among others • Recommended by associations of dyslexia (Madrid, Barcelona, Balearic Islands, Galicia, SUMDIS, ForDyslexia, among others) • On TV, radio and newspapers, blogs & talks
  • 25. Championship! • First Dyseggxia contest for children at Mobile World Centre, Barcelona • Overcome dyslexia & make friends • Sponsors • Organizers
  • 26. First Prize in Education Category • over 200 apps (4 categories)
  • 27. Ongoing Work • Android and Web version • Inclusion in schools • Inclusion reeducation programs • Extend to more languages • Include a business manager in our team • Include a customer service representative in our team • Find funding to become a start-up • Android beta version • Ajuntament de Barcelona (licenses and instruction classes in schools) • — German with 
 Hochschule Emden/Leer
 — Catalan with 
 Calatan Dyslexia 
 Association 

  • 28. Other Possibilities of Dyseggxia • We discovered that some people is using it to... ! ! ! ! • We can create books for children and school materials • Learning new languages • Practice spelling • Mind training for children, adults and elderly • Learning spelling for low-literate adults
  • 29. Summary • Fosters equal opportunities • Improves the outcome • Empowers teachers and parents • Scientifically validated • Learning while playing, engaging • More affordable (and complementary) compared to reeducation classes with a private teacher (0.79€ vs 30€/h)
