The origins, history, work, and aims of the International Commission on Mathematical Education (ICMI) are described. The changing structure of the International Congresses on Mathematical Educational (ICME) are noted. (MNS)

Presents the biography of A. Z. Krygowska (1904-88) covering her school years, university studies, and professional work as a teacher, teacher educator, and scientist. Emphasizes the influence of her teaching experience on both her interest and scientific work in the didactics of mathematics. (12 references) (Author)

Illustrates the pedagogical implications embodied in Liu Hui's discussion on the ancient Chinese mathematical classic "JIU ZHANG SUAN SHU" (Nine Chapters on the Mathematical Art) with respect to aspects of proof and, more generally, the role of proof in mathematics. Provides examples involving area and volume. (Contains 25 references.) (MDH)

Presents and analyzes several proofs of a property of the area under a hyperbola credited to Gregory of Saint-Vincent, a seventeenth-century mathematician. A historical perspective shows a connection between culture and the discovery of a mathematical theory. The universality of mathematics implies a variety of procedures. (Author/MDH)

Pays homage to Freudenthal, a man who knew no cultural boundaries and who opposed obscurantism. His thoughts and works went in many complementary directions--mathematics, history of mathematics, mathematics education, and philosophy. He opened mathematics education to everyone and never lost the intellectual requirements of a great scientific…

Gives an impression of the way Freudenthal worked on mathematics education during the period after World War II, until the early seventies. Shows how Freudenthal approached research, both in education and in mathematics education. Examines two core themes in detail--learning mathematics and developing mathematics education. (Contains 52…

Recorded are some biographical data about the late professor Freudenthal along with some indications about his mathematical work. In an appendix, a tiny part of his mathematical work which can be explained in a fairly direct manner is discussed. (Author)

The use of graph paper is traced from its origins in research reports in the early 19th century to massive use in the early 1900s. Reflected in this report is the impact of "squared paper" on instructional practices and courses in technical, scientific, and mathematical areas. (MP)
