John "Jack" Lee

It's rare to find a professor as caring, attentive, and "merciful" (in terms of grading) as Professor Lee. Yes, the material got a lot more difficult after the midterm, however, as a math-proof class, he could have been much more pedantic with us. But he wasn't harsh on grading, Instead, he focuses on what we learned and the learning experience.

He's a great lecturer, and has a gift for explaining concepts in a way that anyone can understand. His lectures are organized and he always stops to address any questions anyone has. He's very pleasant to talk to and is always happy to help. He really set a solid foundation for me for mathematical proofs. One of the best teachers I've ever had.

Jack is a great professor, very knowledgable, willing to help you, ORGANIZED, and he knows how to teach. Recommend him to everyone! Midterm was okay, but final was hard, my grade dropped a lot after the final. HW wasn't bad, it did take me sometime to do it. Better learn how to use LaTex, hand-writing these HW can be a bit painful.

He is the best. I enjoyed math in his class more than ever! Absolutely reccommend!

I was in Dr. Lee's math 444 and 445 class during summer quarter. I have to admit that it was one of the best math courses I have ever taken at UW. Lectures are super interesting and clear. Read the textbook and attend discussion sessions (really helpful) and you won't regret it. I highly recommend taking his class because you will learn a lot.

Good lord this class was hard and the amount of HW he assigns every week is absolutely ridiculous.

The best Math professor I had ever. Though the course is not easy, he taught everything really clear. And he always answer questions on discussion board. Love the class so much.

Love his class. Best math teacher I ever had. Learned a lot about how to write proofs mathematically. His lectures are clear and well organized.

His course notes on geometry skip over "obvious" subconclusions but when the hw is graded the TA expects complete and obvious detail. this makes the class a huge pain because it will take hours to reread his notes to do well. 40% hw is ridiculous, he tries to work you to the bone but ultimately accomplishes nothing by using his own vocabulary and t

Prof. Lee teaches Math 444/445: Geometry for Teachers. This is the best course I've taken at UW. You'll learn lots about how to write proofs and how to understand plane geometry from the ground up. Lee is an excellent writer and a great lecturer. You'll never be bored. Two thumbs up!

This class just about killed me but one of the most amazing and brain stretching classes i have taken.

A very good professor. He cares about his students and enjoys teaching. His lecturing style is very clear and succinct. In 310, the tests aren't to hard, however the homework assignments are very long. I definitely recommend his 310 class. Even if you aren't a math major, you will come out of it with an entirely different perception of mathematics.
