Teaching Necessary and Sufficient Conditions and Others with Examples
I came across this post at Show-Me the Argument, the blog of Mizzou philosophy grad students. I often find that it can take a while for some of these things to click in the minds of my students. Offering a variety of examples is one good way to get the desired result. Apart from the ones at the Mizzou blog, does anyone have some especially effective examples in this area that you'd like to share?
