Many people have responded to my recent question about Algebra II as a HS graduation requirements, and thank you all who have responded so far. I would still like to hear from others.But, as I read some of the responses, another question came to my mind - which is the subject of this discussion.I hear a lot about the importance of "rigor" in a mathematics curriculum, but what does "rigor" mean? Sometimes I wonder if people are simply equating "rigor" with "difficult" or "challenging." I think mathematicians use the word "rigor" in a different sense - a rigorous course is very much a proof-based course.So, I'm wondering what we mean by "rigor" when we say a math curriculum should be rigorous.
