Overview of the content of this presentation

• Learning to read highly transparent orthography

• The developmental association between spoken and written language skills – highlights from the

Jyväskylä Longitudinal study of Dyslexia (JLD)

• Introduction to the JLD: goals and design

• Overview of the predictive relations and their modelling

• Early identification of children in need of support

• Supporting reading acquisition

.. Learning the connections between spoken and written language using a learning game - Graphogame

The concept of reading skill

• Basic reading skill – ability to pronounce written words accurately

• Literacy – readiness to comprehend fluently written language; requires

– sufficient mastery of the spoken language meant to be learned to read

– accurate and fluent basic decoding skill

– a lot of reading to acquire functional reading skill

– appropriate vocabulary knowledge, motivation and strategy to comprehend the written language

Results from COST A8, Seymour, et al. 2003

Reading acquisition and the consistency of the connections between spoken and written language

• If the reading instruction is organized as it should… the time child needs for the acquisition of the basic reading skill is the shorter

– the smaller the number of connections one has to learn (Finnish, Swedish.. < 30 letter-sounds)

– the more consistent are the connections, ie. the fewer complexities/alternatives need to be learned and

– the more optimally built phonics instruction is available for successfully engaging the child in training the skill

..when biological factors compromise reading acquisition..

The goals of the JLD

to identify

(from children at familial risk for dyslexia)

precursors of dyslexia

predictors of compromised acquisition

developmental paths leading to dyslexia

The last step: the development of preventive measures

(mean = 0, sd =1)

Individual profiles of the prediction measures of the JLD children whose reading acquisition was most severely compromised

Precursors/predictors: conclusions

• Familial background increases the risk of dyslexia substantially – relatively the more so, the more severe reading difficulties are attended

• Speech perception is predictive from 6 months and does so at school age still after controlling for other known predictors

• Among at risk children very early language delays can be informative, both in the expressive and receptive language domains but receptive language may be more important

• Poor letter name learning predicts without false negatives

(false positives should be accepted)

• Naming fluency predicts the most persistent difficulties

…also when the phonological skills revealed by traditional assessment tools fail to predict

How to support reading acquisition among at risk children

GraphoMath

A learning environment for L1 and L2 spoken and written languages: Graphogame

Introduces reading skill of any wanted language

Teaches the phonetic basis of language with the help of written language

– Tunes the speech perception for the use of a wanted language

– Helps in training correct pronunciation of the sounds of a language

– Introduces spoken words (vocabulary) via written language

How and where Graphogame works

• Applies phonics: trains the connections between spoken and written items in optimized order: from easy to differentiate to more similar phonemic units … from letter-sounds to syllables and words

• Adapts automatically to child’s actual skill level

• Guarantees experience of success (80%)

Successful preventive practice

Effective if not used too early, starting just before child enters school

– practiced > 1 times per day in subsequent days

– short < 12 minutes’ sessions

– playing in so ”active” form as possible (by e.g. repeating the sounds)

– the task of parents: to show that they are happy when child plays

– playing long enough (2-20 hours)

Potential assessment use of

Graphogame

• Dynamic assessment:

– Online follow-up of the proceedings of the training of the letter-sound connections

– Application of the observed results to guiding the next steps of the practice towards contents still in need of further practice i.e. integrating assessment and intervention as made in the response-to-intervention model

…note, the cycle of refocussing the intervention can happen in seconds

Supporting Finnish children

• All children entering school this autumn are screened

– for familial risk and/or letter knowledge < 7

Motivating children showing such a risk to play dynamic assessment version of Graphogame

> resistance to training with optimal phonics

 Children showing resistance (1-2%) followed individually for testing the limits of the Graphogame

 Note: percentiles 3-15% trained successfully

GRAPHOLEARN model

• Ekapeli/Graphogame used under the responsibility and funding of the Ministry of Education in Finland

• > 200.000 users (2006-)

• Centralized automatized feedback from our servers

• Could work as main model for implementations elsewhere as well

The basic principles of Graphogame development for a new writing system

• Careful study of the written language environment with local experts for developing and implementing an appropriate content

• Evidence-based documentation of the efficiency of the game of the content before any distribution

• Distribution and use under the responsibility of the local Ministry of Education after research has shown its efficiency in a new orthographic/cultural environment
