The purpose of this paper is not to review all or even much of the past or current research in mathematics education; this has been done elsewhere. Monographs covering research in mathematics education up to about 1960, for example, are available from the U.S. Department of Health, Education and Welfare. Some of the NCTM yearbooks also provide a good source.
