"...What makes work 'scientific' is a matter of continuing controversy and is not a matter to be settled here; but we may at least agree that science is a form of social practice that goes on, with wide variations, in groups recognized as scientific...We see school-age students as ... having about 500 years of science to catch up on... They can begin functioning as real scientists as soon as they are able to engage in a form of social practice that is authentically scientific, one that is concerned with the solution of recognizably scientific problems in recognizably scientific ways."
