T- 520 Computers and the Learning & Teaching of Mathematics

General Course Information

The purpose of this course is to give students a different vision of what primary and secondary school mathematics might be but is not now. The necessary mathematical background for the course is that which a competent high school student with a course in algebra and geometry can be expected to have acquired.

The course is outlined below. The phrases in boldface are software titles that will serve to structure the class discussion. These pieces of software are available during the term on the computers in the computer laboratory. Students are expected to spend of the order of two to three hours per week outside of class working with these pieces of software as well as with selected applets on the web.

In addition to attending lectures, students registered in the course are expected to work on the problems that will be distributed throughout the semester. Students are encouraged to work on the problem in groups of n=2 or 3 (not n=1 or n >3). Problems are to be turned in and will be discussed in class. They will not be formally graded.

The grade for the course will be based on the basis of participation in class discussion and either a term paper on an appropriate topic or an implemented piece of software useful to a mathematics learner and/or teacher.

Proposals for term paper topics or software designs are due before the Thanksgiving break.

There is a substantial literature in this field. Perhaps the most useful pieces of pertinent literature, in terms of providing an intellectual framework for the course are

The International Journal of Computers for Mathematical Learning, Volume 4, Nos. 2-3, 1999

Chazan, Daniel, Beyond Formulas in Mathematics and Teaching: Dynamics of the high school algebra classroom, 2000, Teachers College, New York

An eclectic collection of pertinent materials is on reserve in the library. In addition, an extended bibliography of readings is available for interested students. There is a small collection of photocopied assigned readings assembled into a course packet that may be purchased at Gnomon Copy.

Students should feel free to contact me with any questions. I can be reached unreliably at my office in Longfellow Hall at the Graduate School of Education - the relevant phone number is 495-9373. However, I can be reached reliably by email – JUDAH_SCHWARTZ@HARVARD.EDU - I try to answer my email promptly. When necessary and desirable I will be happy to meet with you.
