Introduction to Mathematical Thinking
Keith Devlin
Learn how to think the way mathematicians do - a powerful cognitive process developed over thousands of years.
If you are reading this, congratulations on getting this far. Mathematics transition courses are notorious for losing students -- even full-time students in a regular university course, with a live professor or TA to give them personal attention.
This week you get a test run of the peer review process that will be used to grade the final exam. Assignment 9 will come in two formats: the regular PDF plus a live, interactive version online. If you look at the left-hand navigation bar, you will see a new entry in the "Course materials" section: "Peer assessments". That is where you will access the interactive version of Assignment 9 (and of the final exam when it is released at the start of Week 6).
Use of the peer review system for Assignment 9 does not involve the grading training, nor will you be able to submit grades for submissions of fellow students or of yourself. Rather, its use in this assignment is purely to provide you with an opportunity to familiarize yourself with the basic peer review mechanism and to practice grading work of other students, using the grading rubric.
Note that grading proofs of other students can contribute significantly to understanding what a proof is and how to construct one. (I suspect most professors came to truly understand what constitutes a good proof only when they started grading proofs as TAs, when in graduate school. That is certainly true for me!) So you should approach it as a part of your learning process, not a chore to be gotten through as quickly as possible in order to complete the course.
I believe participation in a peer review process will form a significant -- and essential -- component of advanced mathematics courses in MOOCs. For sure it won't be perfect this first time out. But there has to be a first step, and this is it!
Submission of the final exam and completion of the peer review process is required in order to be eligible for Distinction in the course.
I intend to offer this course again next year (possibly in two formats, running at different paces), so if you find you have fallen too far behind to stay on top of the material in Week 5 (which has far more mathematical content than the first three weeks did), you might want to consider simply auditing the remainder of the course and enrolling again next year.
