Many secondary school boys do not have the stamina to read beyond the 100th page of a book, research suggests. Teachers also revealed that classics of English literature, such as those by Jane Austen, are putting boys off reading. Some 70% of the 500 teachers surveyed for publishers Pearson said boys had switched off by the 100 page mark. This is leading many teachers to ditch longer novels in favor of shorter books, it adds. Nearly a third of the teachers questioned said boys were put off before the book had even been opened, if they saw it had more than 200 pages.
