While much has been written concerning curriculum evaluation and the preparation of criteria for course-of-study revision, the dis cussions have been confined to a limited point of view, presenting only one type or method for setting up criteria. No one individual or committee has attacked the problem from its many possible angles. The writer surveyed the problem of course-of-study evaluation in arithmetic in a comprehensive manner, in order to set up a definite body of criteria and to formulate a specific procedure based on objective material. Statement of the Problem. The purposes of this problem were (i) to develop a tech nique for evaluating courses of study and syllabi in arithmetic, and (2) to apply this technique to a critical study and evaluation of the New York City Course of Study and Syllabus in Arithmetic of 1929, for Grades I to VI. General Procedure. The general nature of the first portion of this problem was to col late a body of criteria for evaluating courses of study in arithmetic from an examination of informed opinion, judgments, and sugges tions of educational and arithmetic experts, educational investigations, research studies, and statistical and experimental data. The technique thus derived was applied in the second portion of the problem to a critical study of the New York City Course of Study and Syllabus in Arithmetic of 1929, for Grades I to VI. The sources of the material used comprised 623 articles culled from a number of period icals published since 1900, as well as from many books in the field of education, curricu lum construction, and the teaching of arith metic. From this mass, 174 items were sum marized and critically evaluated. For the complete bibliography, the reader is referred to the author's dissertation for the doctorate.1 The Evidence. The evidence for the con clusions was set forth in ten chapters and thirteen tables,1 a brief summary of which follows:
