Kindergarten might be the new 1st grade but it is still too easy. A forthcoming study in the peer-refereed American Educational Research Journal finds that students make bigger gains in reading and math when they learn more advanced content such as adding numbers and matching letters to sounds. Yet kindergarten teachers spend nearly twice as much time on basics such as alphabet recognition and counting out loud. Study authors Amy Claessens,Mimi Engel and Chris Curran found that the majority of kindergartners already know how to do these things when they start school.
"If you teach kids what they already know, they're not going to learn as much," said Claessens, an assistant professor in the Harris School of Public Policy at the University of Chicago and the mother to a kindergartner. "I would go even further and say more time on basic [content] is actually harmful to kids particularly in mathematics. In reading, it is neutral, but math is negative."
