Dyslexia is biological in origin, but environmental factors also play a role. It affects people differently, but typical difficulties include reading, writing, and spelling, limited working memory capacity, and difficulties with organization, sequencing, and concentration. Early identification is crucial so that learners can receive the support that they need. This book explores contemporary perspectives on dyslexia. It starts by outlining approaches to support dyslexic students drawn from the application of cognitive science. It moves on to consider treatments, the role of technology, and approaches for working with teaching assistants.
