Dr. Charles Potter’s Reading Fluency Programme implements individual learning programmes focusing on children’s learning needs. The methods and materials can be used in the treatment of dyslexia, as well as for working with children with reading, writing, and spelling difficulties or difficulties with rate of work at school. The programmes are activity-based, and are introduced through online sessions related to the child’s individual learning needs as identified through initial assessment and ongoing evaluation. Based on assessment, an individual programme is developed for the child, focusing on areas of need. The programme then uses electronic books, activity books and materials for treatment of phonological and phonemic difficulties, phonic difficulties, as well as linked problems with reading, writing, spelling, reading comprehension and working memory development. This chapter provides theoretical background on the neurolinguistic basis of the programme’s methods and materials, which have been developed internationally and implemented pre COVID with both first and second language speakers of English. It also provides information on how the materials have been implemented post COVID using activity-based online learning formats, and the results of children based on pre and post assessments.
