Should e-books replace picture books in schools?
E-books are increasingly being used in classrooms by children as young as three - and they are making a big difference to the reading habits of boys. But there are concerns the expansion of electronic devices in schools may undermine the position of traditional paper books.
The National Literacy Trust has been conducting research in schools in England over the past year to understand their impact.
It found that on average boys made 8.4 months of reading progress using e-books, compared to just 7.2 months of progress among girls.
Irene Picton, from the National Literacy Trust and author Michael Rosen discuss the benefits of e-books and picture books.
