WelcomeFrom the Math 23 course syllabus
Learning proofs can be fun, and we have put a lot of work into designing an enjoyable way to learn high level and challenging mathematics! Each week's course materials includes two proofs. Often these proofs appear in the textbook and will also be covered in a Tuesday lecture or as a sample problem on Thursday. They also may appear as quiz questions.
You, as students, will earn points towards your grade by presenting these proofs to teaching staff and to each other without the aid of your course notes. Here is how the system works: When we first learn a proof in class, only members of the teaching staff are "qualified listeners." Anyone who presents a satisfactory proof to a qualified listener also becomes qualified and may listen to proofs by other students. This process of presenting proofs to qualified listeners occurs separately for every proof.
You are expected to present each proof before the date of the quiz on which it might appear; so each proof has a deadline date. Each proof is worth 1 point. Here is the grading system:
- Presenting a proof to Paul, Kate, one of the course assistants, or a fellow student who has become a qualified listener: 1.0 points before the deadline, 0.8 points after the deadline. You may only present each proof once.
- Listening to a fellow student's proof: 0.1 point. Only one student can receive credit for listening to a proof.
- After points have been tallied at the end of the term, members of the course staff may assign the points that they have earned by listening to proofs outside of section to any students that they feel deserve a bit of extra credit.
Either you do a proof right and get full credit, or you give up and try again later. There is no partial credit. It is OK for the listener to give a couple of small hints.
You may consult the official list of proofs that has the statement of each theorem to be proved, but you may not use notes. That will also be the case when proofs appear on quizzes and on the final exam.
