Undergraduate Program:
Teaching Communication Skills

Those of us who have been teaching for some years will probably agree that students often lack sufficient communication skills. Teaching such skills tends to be an incidental part of imparting mathematical knowledge. This is especially true of beginning courses where emphasis has traditionally been on learning basic concepts and techniques. However, over the last few years we have seen developments in our department, and in the University as a whole, that place learning communication skills on a more even footing with gaining command of the course material itself. This is a desirable change, since there is a real need for good communication skills in the workplace as well as in graduate study. In this note we would like to outline some related developments.

To begin with, we are happy to say that our department has been somewhat ahead of the curve. Thus when the University's new writing requirement of at least one writing intensive course in each student's major took effect in the Fall 1999, we had just the right kind of course for this purpose. It was Math 2283, "Sequences, Series and Foundations," developed by Professor Wayne Richter about ten years ago as a transitional course between lower level courses emphasizing basic manipulative skills and more advanced courses with more attention to proofs. In this course students have been expected to make a serious effort to write simple proofs in a setting familiar to them from the first two years of calculus. In Fall 1999 this course was upgraded to Math 3283W where students are expected to carefully write proofs of theorems and expositions of the subject matter. In order to get the maximum benefit from their assignments, students in writing intensive courses must typically rewrite their papers at least once after getting the instructor's feedback. Most math majors are now satisfying their writing requirement by taking this upgraded course. We also continue to offer the original course, Math 2283, for students who satisfy their writing requirements in other ways. Another way to satisfy the writing requirement is by writing a Senior Project paper (Math 4997W. All CLA math majors are required to do a Senior Project). A faculty member guides the student in the writing of the paper which must be at least ten pages long. It is also required that the project demonstrate acquisition of new mathematical material. Extra one-on-one student-faculty contact is an added benefit of the senior projects.

Here are the titles of the Senior Projects carried out to date, together with the names of the faculty advisors. Professor Paul Garrett supervised three such projects: "The content of sports statistics," "The Enigma Cipher," and "The NP-completeness of well-posedness of positions in the game of Minesweeper." Professors Bert Fristedt and Max Jodeit have supervised one project each: "WallisÕs attempt to prove the parallel postulate," and "The definition and properties of the complex exponential function." In the articles "Thoughts on Writing Skills" and "Senior Project Goals," Professors Garrett and Fristedt share their thoughts about teaching writing skills and about the goals of the projects.

We would also like to mention some other approaches involving interactive learning that our faculty are using to improve student communication skills in our IT Calculus and Mathematics for Elementary School Teachers courses. In IT Calculus the in-class time is divided into two hours of large lecture, one hour of recitation and two hours of lab/workshop each week, compared to three hours of large lecture and two hours of recitation in the traditional format. Both faculty and TA's participate in the lab/workshop sessions but not in the recitation sessions, thus there is an additional one hour of faculty-student contact per week in the new format. In the lab/workshops students develop verbal technical communication skills by interacting with each other as well as with TA's and faculty, while at the same time "learning by doing." Use of graphing calculators, Matlab and Mathematica during the second year allows treatment of more interesting applied problems than can be done in the traditional course. And, from the very inception of this format, students have been required to write more: already in the January 1998 issue of this newsletter it was noted that in the fourth-quarter course in fall 1997 students wrote up four lab reports.

In the elementary school teachers' course there is no formal division into lectures and recitations (or labs). Rather, the professor briefly explains a concept, assigns a suitable problem illustrating it, and then students break up into groups of four to work on the problem. After a few minutes, typically not more than ten, a student presents the work done by her/his group at the blackboard. Another problem is then assigned, or a new concept explained, and so on. The expectation is that any student in a group should be able to do the blackboard presentation. Therefore, even those students who contribute somewhat less to solving the assigned problems have to communicate, both within the group and at the blackboard. The examinations are more traditional, requiring individual work.
