# Student Learning Goals

### Undergraduate Student Learning Initiative

Mathematics is the language of science. In Galileo’s words:

*Philosophy is written in this grand book, the universe, which stands
continually open to our gaze. But the book cannot be understood unless
one first learns to comprehend the language and read the characters in
which it is written. It is written in the language of mathematics, and
its characters are triangles, circles, and other geometric figures,
without which it is impossible to understand a single word of it.
Without those, one is wandering in a dark labyrinth.*

Mathematics majors learn the internal workings of this language, its central concepts and their interconnections. These involve structures going far beyond the geometric figures to which Galileo refers. Majors also learn to use mathematical concepts to formulate, analyze, and solve real-world problems. Their training in rigorous thought and creative problem-solving is valuable not just in science, but in all walks of life.

### Learning Goals for Mathematics Majors

The Mathematics Department offers three majors:

(1) the Major in Mathematics,

(2) the Major in Mathematics with a Teaching Concentration, and

(3) the Major in Applied Mathematics.

Most of the learning goals for these majors are common to all three.

**General skills**

By the time of graduation, majors should have acquired the following knowledge and skills:

- Analytical skills
- An understanding of the basic rules of logic.
- The ability to distinguish a coherent argument from a fallacious one, both in mathematical reasoning and in everyday life.
- An understanding of the role of axioms or assumptions.
- The ability to abstract general principles from examples.

- Problem-solving and modeling skills (important for all, but especially for majors in Applied Mathematics)
- The ability to recognize which real-world problems are subject to mathematical reasoning.
- The ability to make vague ideas precise by representing them in mathematical notation, when appropriate.
- Techniques for solving problems expressed in mathematical notation.

- Communication skills
- The ability to formulate a mathematical statement precisely.
- The ability to write a coherent proof.
- The ability to present a mathematical argument verbally.
- Majors in Mathematics with a Teaching Concentration should acquire familiarity with techniques for explaining K-12 mathematics in an accessible and mathematically correct manner.

- Reading and research skills
- Sufficient experience in mathematical language and foundational material to be well-prepared to extend one’s mathematical knowledge further through independent reading.
- Exposure to and successful experience in solving mathematical problems presenting substantial intellectual challenge.

*Remarks:*

- The skills listed above are not to be acquired
*solely while a major*. Instead, incoming majors are expected to have many of the above skills at some level already from their K-12 education (e.g., some understanding of axioms and proofs from high school geometry). This is essential, because mathematics is largely a cumulative subject. - The skills above are generally not taught directly. Instead they are acquired by students through experience, in the context of studying specific mathematical topics, such as those in the following section.

**Subject-specific knowledge**

Graduating mathematics majors should have learned the basics of “mathematical culture” in the following areas:

elective cluster concerning some advanced application of mathematics. |

### Curriculum Map

The following tables show how both sets of learning goals are addressed in the mathematics curriculum.

**General Skills**

Most of the goals relating to general skills are addressed in all courses. For example, the ability to formulate precise mathematical statements and reason logically with them is a key skill used and taught in all courses. However, some skills are more naturally learned or re-inforced, in certain courses. Some connections are indicated in the following table.

General Skill |
Most Relevant Courses |

(1) Analytical Skills | |

(b) Distinguishing cogent arguments from fallacious ones. | 55 |

(c) Understanding the role of axioms. | 55, 125 |

Once again, however, most of the general skills are learned and used in all courses.
