Introductory Remarks:

Geometry has an important classical side: Euclidean Geometry from the Greeks moving, in the last two centuries, to non-Euclidean geometries (which differ by their assumptions about parallel lines), including spherical, hyperbolic and projective geometries. This transition is one of the critical `paradigm shifts' in the history of mathematics. The hierarchy of geometries (organized by their transformations) will be one theme of the course.
In modern geometry, the interplay of applications, axiomatics, synthetic geometry, analytic methods, and groups of transformations presents a rich mix of mathematical methods and problems to be explored. We will explore simple plane and spherical geometry from several of points of view, beginning with synthetic, but expanding to include analytic and axiomatic approaches.
Geometry also has important modern applications, to such areas as Computer Aided Geometric Design, computer graphics, computational geometry, robotics, modern physics, biology and engineering. Even how geometers such as myself practice geometry (and teach geometry) is changed by new computer programs, such as The Geometer's Sketchpad. This program has now been purchased for all schools and all teachers in Ontario, and its use is required in the new grade 9 curriculum.

In this course we will explore these plane geometries multiple settings. However, underneath this content, I have some more basic and far reaching objectives: this course is designed to further reflection on the practice, the learning and the teaching of geometry in particular and mathematics in general. As a geometer, and an educator, my deepest hopes for this course include that it will:

To be more modest, my expectations are that by the end of the course you will:

Prerequisites: The formal prerequisites are minimal: I will assume familiarity with linear algebra (vector spaces, matrices, linear transformations, eigen vectors) and some mathematical maturity. All other background will be developed as needed.

I will expect you to:

In addition, I encourage you to use the resources of the Internet to track information and discussions about geometry. I can suggest several electronic news groups as well as the following web sites linked on my page of interesting geometry sites. For any people preparing to become mathematics teachers, these resources will be important support for your practicum courses and for your teaching.

Text: We have one text for the course, plus other supplementary materials. We will begin working from the text at the second class, but will not cover all of this text.

These are for sale, including some used copies, in the bookstore. There is a new edition from the publisher, but this is not required for our course. We will cover, at least, the first 10 chapters of the first edition, during the fall semester.

Other reference materials are on reserve, on a variety of related topics. Further materials are in the course cabinet in the classroom and can be borrowed from the instructor.

Evaluation: Graded work will be something like:

  1. regular assignments, including proofs, conjectures, (approx. 50%)
  2. reflections on learning and geometry (selections from a geometry journal) have now been included in each assignment;
  3. the major project, marked in stages, including preliminary proposals and drafts, presentation in class, and written (drawn?) final form, with reflections (approx. 40%);
  4. participation in in-class work (sheets from in class activities turned in, with signatures) (10%)

Every assignment should end with a page (or so) of your current questions, or responses to an ongoing dialog with the instructor and the tutor, provoked by previous questions. As was noted above, developing your voice to ask geometric questions is an essential objective of the course. (See the handout on evaluation standards .)
