This bulletin is based upon reports to the International Commission on the Teaching of Mathematics concerning the development of the teacher of mathematics in the better secondary schools of different countries. For the most part, only those schools which are under the immediate direction of the Government have been considered. And even here discussion is limited to the best schools for boys and to the teachers in such schools. As a rule, the schools for girls are not as completely organized or of so high a standard. Included in this bulletin, when possible, are brief independent sketches of the educational conditions in the various countries, so that the readers may receive here in connected form condensed but definite accounts of the following phases of educational work in the country under discussion, in so far as they bear on the preparation of teachers of secondary mathematics: (1) the general educational scheme; (2) secondary schools and their relation to that scheme; (3) the mathematics taught in the secondary schools and the pupils to whom it is taught; (4) the inducements (such as salary, pensions; social position) to young men to take up secondary-school teaching as a profession; (5) the universities of the country, the courses of mathematics and allied subjects they offer, and the diplomas or certificates they confer. The countries profiled include Australia, Austria, Belgium, Denmark, England, Finland, France, Germany, Hungary, Italy, Japan, the Netherlands, Roumania, Russia, Spain, Sweden, Switzerland, and the United States. The following are appended: (A) England: Cambridge local examinations, senior students; Oxford and Cambridge schools, examination board; University of London, matriculation examinations; (B) England: Entrance scholarships examination papers, Cambridge University; (C) France: Concours for admission to the Ecole Normale Superieure and for the Courses de licenses in 1913; (D) Agregation des sciences mathematiques; (E) Germany: Reifeprufungen; Lehramtsprufungen; (F) Japan; Examination questions.
