Math.221.005 Calculus 1 Fall 2012
Course Objectives
Loosely speaking, the goals of the
course are as follows:
- to understand the important concepts of calculus
- to learn to carry out certain types of operations, and to be
able to apply those operations to solve problems
- to write coherently and correctly about calculus
methods. This includes being able to formulate and effectively
communicate a problem analysis and solution using methods of calculus
- to recognize problem situations for which calculus methods are
applicable, and to be able to understand analyses of such problem
situations that make use of calculus methods
- to understand the general characteristics of the mathematical
method.
Admittedly, parts of this list are vague. Paradoxically, in
order to understand a more specific set of objectives, you would
already need to know calculus. The objectives would naturally
mention new concepts and use terminology that you will learn in the
course, but which would not make any sense to you now (unless you have
already studied calculus).
To make an analogy, imagine that you have completed a study of the
arithmetic of whole numbers -- that is, addition, subtraction,
multiplication, and division of integers greater than or equal to
zero. Next you will take a course on the arithmetic of rational
numbers. The goals of instruction would mention concepts like
fractions, negative numbers, reciprocals. But until you have
studied rational numbers, these terms have no meaning, or what is more
confusing, a meaning in everyday usage that is quite different from the
intended meaning in the course.
In a sense, a math course is similar to a course in a foreign
language. A
fundamental goal is to master enough of the vocabulary and grammar and
idiom to carry on a conversation. You might say that every
mathematical subject corresponds to a different language, say
Algebraish for algebra, Trigish in trigonometry, and Calculish for
calculus. Of course, these aren't really separate
languages. Each mathematical language is actually a specialized
part of your normal language. That can give you a misleading
impression. You can listen to me conversing in Calculish and
think you are understanding it, because you understand the regular
English parts of it. However, true understanding only occurs when
we can communicate our ideas to each other, and that is impossible if
my ideas concern concepts you have not yet learned. From this
perspective, the point of studying calculus is to learn a new dialect
of English, namely Calculish, and to learn it well enough to understand
spoken and written conversation. In a word, your goal is fluency.
Many students are required to take calculus as they pursue majors in
other disciplines, like biology, or physics, or economics. If you
are one of these students, fluency in Calculish is probably the most
important goal of the course. That is because there are
important applications of calculus in your major. Your completion
of calculus 1 is not necessarily so that you can actively apply it in
your future work, or even so you can make direct use of results others
have obtained using calculus. Rather, it is so you can
participate meaningfully in the conversation.
This is a key observation about the objectives of the course.
Learning the methods and memorizing the definitions and being able to
solve homework problems accomplishes little or nothing if you do not
gain fluency in the process. That is why the first
objective listed above concerns conceptual understanding, and why
writing coherently and correctly are also included.
The last objective on the list is probably the vaguest of them
all. It reflects the fact that mathematical knowledge is
developed in a highly stylized form. Think of it as a combination
of grammatical structure and idiomatic usage that underlies all
mathematical language. True fluency demands an understanding of
the grammar and idiom of the language. And this is especially
true for mathematics, because its structure is so different from normal
conversational language. Over the course of the semester, you
will see how this structure appears in the specific context of
calculus. The better you understand the structure, the greater
your ability to converse fluently in Calculish. I refer to these
as general characteristics of the mathematical method because they
pervade all of mathematics. Developing an understanding of this
structure of mathematical knowledge is an important general education
goal, because it gives you access to a broad literature of mathematical
analyses and methods.
