This Course at MIT

Course Overview

This page focuses on the course 18.310 Principles of Discrete Applied Mathematics as it was taught by Professor Michel Goemans, Dr. Lorenzo Orechhia, Dr. Richard Peng, and Susan Ruff in Fall 2013.

This course introduced students to topics such as probability, counting, linear programming, number-theoretic algorithms, sorting, data compression, and error-correcting codes. It was also a Communication-Intensive in the Major course.

Course Outcomes

Course Goals for Students

  • Gain a basic understanding of topics in discrete mathematics
  • Begin to communicate successfully as mathematicians

Possibilities for Further Study/Careers

This course prepared students to enroll in courses such as 18.312 Algebraic Combinatorics, 18.440 Probability and Random Variables, and 6.006 Introduction to Algorithms.

 

Instructor Insights

In the following pages, Michel Goemans, Peter Shor (a colleague in the Mathematics Department), Lorenzo Orecchia, and Susan Ruff describe various aspects of how 18.310 Principles of Discrete Applied Mathematics was developed and taught.

Student Information

66 students took this course when it was offered in Fall 2013.

Breakdown by Year

About 50% sophomores and 50% juniors.

Breakdown by Major

Almost exclusively Mathematics majors or students with a double major in Mathematics and another concentration.

Typical Student Background

Many students entered the class with limited experience writing mathematical proofs.

Enrollment Cap

Enrollment in the recitations was limited to about 20 students in order to enable instructors to provide students with adequate writing support; this cap largely determined the overall enrollment cap of 70-80 students in the course. 

 

How Student Time Was Spent

During an average week, students were expected to spend 12 hours on the course, roughly divided as follows:

Lecture

3 hours per week
  • Met 3 times per week for 1 hour per session.
  • Instructors demonstrated technical aspects of discrete applied mathematics; at the end of some lectures, they conducted computer demonstrations of key concepts.
 

Recitation

1 hour per week
  • Met 1 time per week for 1 hour per session; mandatory attendance.
  • Instructors and students further discussed course content and how it related to professional writing and oral communication in the field of mathematics.
 

Out of Class

8 hours per week

    Students completed problem sets and writing assignments, including a term paper.
