The question, "What is worth knowing?" fascinates me. I love to work on it; deciding what to teach my students; weeding wordy textbooks. In fact one of my personal goals is to write my own biology textbook for a class I teach at GSIS.
Believe it or not, one of the hardest things in education is identifying what to teach or what should be taught. I have found some great material and will supply links to the original, where it can be found, and otherwise will publish material that I consider valuable directly on this page.
