Text:  Saul Stahl, Introductory Modern Algebra: A Historical Approach, Wiley
Time and space:  TR 9:30 - 10:45 a.m., 1003 Malott

About the course:  The great themes of modern algebra are algorithms (how to calculate things); unity (seeing the same thing from different points of view; seeing many things from the same point of view); and structure (working directly with an underlying structure that manifests itself in superficially very different ways). A historical approach allows us to see how the general arises from the specific, and allows us to trace basic themes as they develop over time.

How classes are structured:  In most classes there will be both in-class group work and lectures. Questions are always encouraged.

Your responsibility:  You are responsible for doing homework and handing it in on time, studying for and taking exams, participating in group work in class, and preparing for class by doing assigned readings.

If you're new to writing proofs: Many students have found the book How to read and do proofs by Daniel Solow to be very helpful. I will be happy to meet with you to work through as much of it as you need.

Homework problemsHomework will be assigned nearly every class, mostly due on Thursdays.  Homework assignments can be found here.  Answers to homework can be found here.

Your grade:  Your grade will be based on homework, two midterms, one final, and the reading quizzes (explained below).  The breakdown is:

Homework:  100 points
First exam:  100 points
Second exam:  100 points
Final exam:  200 points
Reading quizzes:  50 points

What is a reading quiz?  A reading quiz briefly asks about reading assigned in advance of class.  It does not ask for detail.  For example, if you were assigned to read in a calculus class about the definition of derivative, you might be asked, "The derivative f'(a) is the slope of what line?" A perfect answer would be, "The tangent line to the curve y = f(x) at the point x = a." But the less precise answer of "the tangent line" would also get credit, because it tells me that you have a pretty good idea what we're about to learn formally. Reading quizzes will be given on random days at the start of class, and will take no more than 5 minutes.

What kind of homework will be given?  Homework problems will be varied, including but not limited to calculations and proofs.  Most of the problems will not be as routine as in, say, a calculus class.

What about late homework?  Late homework is not graded.  But if you can't hand in homework on time, you should do it anyway and come by my office to go over what you did. 

What if I miss a class?  Because a good part of what you will learn comes from in-class group activities, and because of the reading quizzes, it's important to try to come to every class.  If you absolutely have to miss class (for example, if you're sick, or your car broke down on the way in) come by my office to see what you've missed.  Both the homework and reading quiz grades will be calculated so that missing one or two classes will not hurt you.

Important dates:  The first exam is Thursday February 26. The second exam is Thursday April 9.   The final exam is Tuesday May 12, 7:30 - 10 a.m.
