Efficacy of Berni: A software for preschoolers at risk of dyslexia*.

The signs of dyslexia can appear as early as preschool. Teachers need effective and efficient programmes toovercome the difficulties these children face, making use of the available resources. The purpose of this study wasto design an educational software that would enable effective intervention to improve the early difficulties ofchildren at risk of dyslexia, and that a preschool teacher could apply in the classroom in an inclusive manner.Hence, the software named Berni was designed as an early intervention measure to overcome difficulties inphonological awareness, verbal memory, alphabetic awareness, receptive language and print awareness. Thesample included 43 preschoolers aged 4 and 5 years old from 7 schools in the Basque Country (Spain), whoshowed warning signs of dyslexia. To evaluate the software, half of the participants used the Berni software intheir regular classroom and a pre-test/intervention/post-test design was used with a control group. The resultsshowed that multimedia training with the Berni programme helped to overcome difficulties in the variables thatbetter predict dyslexia: phonological awareness, rapid automatised naming and verbal memory. Furthermore,teachers and children consider the Berni software to be perceptible, operable and adequately developed.Teachers consider it to be appropriate to the curriculum, effective and conducive to learning. However,autonomous use, feedback and adaptation possibilities could be improved.
