This publication is a collection of eleven manuscripts which deal with research in mathematics education. Each of the first ten papers is concerned with one or more of the following areas: (1) significant research efforts in mathematics education; (2) the need for both "information-oriented" (basic) and "product-oriented" (applied) research; (3) the complementary nature of basic and applied research; (4) the potential impact of research on the teaching of mathematics; and (5) the implementation of research in the teaching of mathematics. The final paper, written by the editor, focuses on the more important aspects of the preceeding papers and offers a perspective for viewing them. (FL)
