The author remarks on the purpose(s) and content of existing geometry courses and offers alternative purposes and goals for geometry courses and some consequences of this alternative point of view. (JG)

A tentative approach to geometry by the Comprehensive School Mathematics Program (CSMP) is discussed. Included are descriptions of the content for courses in the elementary, middle, and secondary school mathematics. Both Euclidean and affine plane geometry are included. (JG)

The author surveys some aspects of both product evaluation and process investigation as they impinge on mathematics education and curriculum development. Discussion includes summative and formative evaluation, investigating the learning process, and problems inherent in both areas. (JG)

Five recommendations for teaching geometry in elementary and secondary school are presented. These recommendations are a result of the Comprehensive School Mathematics Program second international conference held to investigate the teaching of geometry. (JG)

The author examines conceptual and logical difficulties involved in learning and teaching axiomatic geometry. An organization of the school program in geometry from grade 1 through grade 12 is proposed. (JG)

Presented are the history and underlying assumptions and theories upon which the Comprehensive School Mathematics Program (CSMP) is based. The purpose is to introduce the articles which follow it concerning the second international conference of CSMP which met to investigate the teaching of geometry. (JG)

After a discussion of philosophy and learning processes and theories, the author presents rationale for teaching axiomatics in geometry including traditional and modern transformational approaches. (JG)
