Dysorthography: what are the latest remediation methods validated by research?
Remediation methods for dysorthography have evolved significantly over the past twenty years, thanks to advances in cognitive neuroscience and learning psychology research. Here is an overview of the most effective and most scientifically validated approaches.
Explicit, structured phonological methods: the foundation of remediation
Explicit, structured phonological methods remain, to this day, the most solidly research-validated approaches for remediating dysorthography. They systematically and progressively work on grapheme-phoneme correspondences, from the simplest to the most complex, ensuring that each correspondence is well consolidated before moving on to the next. These methods, recommended by the Haute Autorité de Santé, produce significant and lasting effects on spelling skills when applied intensively and regularly.
Spelling memory training: a complementary approach
Beyond phonology, approaches focused on strengthening orthographic memory — memorising the correct visual form of words — are increasingly used as a complement. The technique of orthographic visualisation, the photographed words method and delayed recall exercises help consolidate orthographic representations in long-term memory. These approaches are particularly useful for dysorthographies with a marked lexical component.
The morphological analogy method
A relatively recent and promising approach is remediation through morphological analogies. It involves working on word families and recurring morphemes — prefixes, suffixes, roots — so that the child can deduce the spelling of new words from words they already know. This approach reduces memory load and promotes the transfer of learning to new words.
Integrating digital tools into remediation
Speech and language therapists (orthophonistes) are increasingly integrating digital tools into their remediation sessions. Software such as GraphoLearn or phonological training apps allow intensive practice with immediate feedback. Used alongside traditional exercises, these tools significantly increase the frequency of training without lengthening session time.
Intensive remediation during the holidays
Recent studies show that intensive remediation programmes — several sessions a week during school holidays — produce greater spelling gains than the same amount of remediation spread over the whole year. These intensive programmes make it possible to exploit brain plasticity to the fullest during dedicated periods.
