Education Secretary Michael Gove told Daybreak that "speaking as a parent" the changes to the national curriculum "can't come quickly enough".
Mr Gove said, "I want my children, who are in primary school at the moment, to have the sort of curriculum that children in other countries have that are doing better than our own".
He stressed that a more "rigorous" curriculum would help children when they compete for college places or jobs in the future.
