  1. 1. by the Cookie Cloud Team A Scientifically Validated App to Help Children to Overcome Dyslexia in Spanish
  2. 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. 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. 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. 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. 6. The Idea • Provide children an interactive and engaging tool • Overcome difficulties while playing exercises created with a new linguistic based methodology
  7. 7. since March 2011

  9. 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. 10. New Methodology
  11. 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. 12. Exercise Design • Phonology • Orthography • Morphology • Lexicon Empirical Error Analysis 
 + Difficulties • Omission ! ! • Substitution
  13. 13. • Insertion • Derivation • Word Separation • Transposition
  14. 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. 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. 16. Engaging Children • The penguin grows and earns prizes (Rello, Bayarri, & Gorriz, TISE 2013)
  17. 17. For Parents & Teachers • Graphics showing the evolution of the child (Rello, Bayarri, & Gorriz, TISE 2013)
  18. 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. 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. 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]
