RIGOR: What it IS. What is ISN'T.

A supremely popular term being thrown around in the wild world of mathematics these days is "rigor." When I interviewed for this position last year, I mentioned adding rigor to instruction. Mr. Shillings (who never misses a trick) asked me to be specific about what I meant by "rigor." GREAT question, and I think/hope I answered it appropriately, but I'm not sure I did as good a job as the following chart.

According to expert Linda Gojak of NCTM,.

Rigor is a balance between procedure, concept, and application of mathematics.
