The utilization of Information and Communication Technologies (ICT) in educational practice is indispensable, while it becomes imperative in the education of individuals with special educational needs, as it promotes the application of Individualized Education Programs. Feedback in digital activities aiming at phonological awareness development is the topic under consideration in the present paper. The study has two objectives. On the one hand to study feedback as a differentiating factor for dyslexia intervention through the use of ICT and on the other hand to search for the type of feedback that helps students with dyslexia the most. The two different feedback types are based on behaviorist and constructivist approaches. Results show that constructivism is the theoretical model that feedback has to be based on, in order activities to be fruitful to students with dyslexia.
