Edward Mitchell, who is chairman of an important group of head teachers, thinks kids only know about pop stars and sports people from the last few years.
Lack of knowledge
He said: "Too many young people don't have a solid basic knowledge of British history."
He says that if you ask any kid who their hero is, they'll say something like Eminem or David Beckham.
Winston Churchill - but what do you know about him?
Mitchell thinks that many stars like this won't be remembered in a few years, unlike people like Churchill or Shakespeare.
He thinks that you need to know about how the past made our society, or you will not fully understand it.
Andrew Motion, the Poet Laureate (who writes poems for important national occasions), recently said that kids don't get chance to read really important books.
Hear Story
Do you have heroes from history?
Who's your Greatest Briton?
'I met my heroes!'
