Brazil phonics longitudinal study

A study in Brazilian public schools found that children flagged early for dyslexia risk made reading gains after a structured multisensory phonics program. (frontiersin.org) The paper was published in *Frontiers in Education* on March 5, 2026 by researchers at the Federal University of Paraná and Universidade Tuiuti do Paraná in Curitiba. It followed 76 preschool and early elementary students across five assessment points. (frontiersin.org) Phonics teaches the link between speech sounds and letters, the basic code readers use to sound out words. Multisensory phonics adds seeing, saying, hearing, and touching or moving at the same time, such as using letter tiles while pronouncing each sound. (readingrockets.org) The Brazilian team sorted children into mild, moderate, and significant risk groups using phonological awareness, rapid naming speed, and short-term or working memory. The intervention ran for four progressive cycles, with 28 sessions in total. (frontiersin.org) The first two cycles used small-group preventive sessions focused on phonological awareness, oral language, and early literacy concepts. From the third cycle on, children were split into small-group prevention or individual intensive support, depending on risk level. (frontiersin.org) By the final assessment, the study reported more children reaching initial and consolidated literacy stages and fewer remaining in pre-literacy. It also found no significant differences at that point between the risk groups and the comparison group. (frontiersin.org) The authors said a small subset of students still showed persistent difficulties, which is why the paper argues for continued individualized support inside public schools. The study also said its screening method helped identify which children needed preventive help and which needed more intensive intervention. (frontiersin.org) That matters in Brazil because recent research has described weak systematized monitoring of reading in schools and the difficulty of identifying students at risk for dyslexia before problems harden over time. A 2025 Frontiers in Psychology paper on Brazilian adolescents said schools need better monitoring and referral pathways for reading disorders. (frontiersin.org) The new paper does not claim every struggling reader has dyslexia, and it does not present multisensory phonics as a one-session fix. It presents early screening, repeated measurement, and layered support as the model that produced the reported gains. (frontiersin.org) The result is a practical school question, not just a clinical one: whether public systems can spot reading risk early enough to intervene before children fall permanently behind. This study’s answer was to start early, teach the code directly, and keep extra support in place for the children who still struggled. (frontiersin.org)
