ABOUT THE COURSE: In this course we will cover most of Chapters 1-6 and Chapter 12 of the text with occassional excursions in the appendices. We will start by examining the familiar set of integers. Our emphasis in looking at the integers is twofold. First, we want to emphasize the algebraic properties of the integers. Second, we want to try to develop the students' ability to understand theoretical mathematical arguments and to be able to write coherent mathematical arguments. Almost all of the mathematical arguments you will be expected to understand and to write take the form of mathematical proofs. Once we gain some experience in the relatively concrete setting of the integers, we will develop some understanding of abstract rings and the functions between them. In this less familiar context, the skills of mathematical argumentation that we developed earlier will become more important to the understanding of these topics. To further our understanding of rings, we then look at the arithmetic of polynomials as an example of a ring that is not the integers. We will then begin the study of quotient fields and the construction of field extensions, the depth of this coverage will depend on the time available at the end of the course.

GRADING: In this course you will be graded on your performance on three one hour in class exams, a comprehensive final exam, and weekly homework assignments. The relative weights of these components will be

Test 1 100 pts (Friday, Feb. 17) Test 2 100 pts (Friday, Mar. 23) Test 3 100 pts (Friday, Apr. 27) Homework 150 pts Classwork 50 pts Final Exam 200 pts (Tuesday, May 8, 3:10 - 5:50 pm, STV 229)

Exam I Solutions
Exam II Solutions
Exam III Solutions
Final Exam Review Problems

HOMEWORK: Homework assignments will consist of four or five proofs a week. Assignments will be given in class and will be due each Thursday by the beginning of class. As developing your skills at writing mathematical arguments is one of the central goals in this course, doing as much as you can on each homework assignment is essential for a good grade. NOTE: In general you should not expect to be able to do a good job on a homework assignment if you start the day before it is due. Some problems may require numerous attempts before you will be able to solve them. As well as the formal written assignments given in class, it will be necessary for most students to read and re-read the relevant sections of the text. For your FIRST READING ASSIGNMENT please read ``Appendix A, Logic and Proof'' (pp. 493-503) in the text.

            This course will introduce a variety of issues of interest to cognitive scientists who study people's tutored and untutored reasoning and thinking skills. We will begin by examining skill in well-defined reasoning endeavors, and explore relationships between formal reasoning and everyday reasoning. Later we will turn our attention to decision making, both with laboratory tasks and in the real world. I hope to get you to think carefully about what it means to reason effectively, and to explore your own reasoning strengths and weaknesses. This course counts toward the cognitive science minor and major, and also toward the cognitive component of the psychology major.

            Course requirements include two exams, two short papers, very short reports of group discussions, as well as occasional “laboratory assignments” where you will be asked to write about examples of reasoning and decision making from your own experience. The two short papers will consist of descriptions of another person’s reasoning or decision-making. They will each be about 5-7 pages in length. The weights of the assignments are roughly the following: each exam, 22%; each short paper, 22%, group discussion reports, attendance, participation, and completing laboratory work in a timely and thorough way, 12%. Due dates for all assignments are provided on the attached schedule. Take note of them and plan your work accordingly. Late papers and assignments will be penalized 3% per every 24 hours late; exams may not normally be made up.

            Readings for the course come from a variety of sources. The required texts are: Halpern, Thought and knowledge (5th ed), and Kahneman, Thinking, fast and slow.  You might also want to purchase your own copy of Perkins, The mind's best work, as we will read a good amount of that book in a very short time. Other readings are on Moodle.  Note that the reading load varies from week to week, and try to plan ahead.  No additional outside reading will be required for the papers, although I assume you will incorporate relevant readings from the syllabus as appropriate.

            This course is always an enjoyable one to teach, and I hope you'll find many of the topics enjoyable, too. I'll be announcing office hours shortly, and hope you'll come by to talk about topics related (or even unrelated!) to the course.
