Peirce And Fisher on the Place of Probability in Abductive Inference
In his analysis of inference into three types, deduction, induction, and abduction, C. S. Peirce maintains that probability plays an essential role in the first two, but not in the third. For a deductive argument, probability tells us the frequency with which the conclusion will hold given the premises; for an inductive argument, probability tells us the frequency with which the argument will hold true. However, probability has no role to play in abduction because there is, in Peirce's view, no

Genetic Origins
The goal of the Genetic Origins Program is to allow students to use their own DNA variations (polymorphisms) as a means to explore our shared genetic heritage and its implications for human health and society. Genetic Origins focuses on two types of DNA variations: an Alu insertion polymorphism on chromosome 16 (PV92) and single nucleotide polymorphisms (SNPs) in the control region of the mitochondrial (mt) chromosome. With two alleles and three genotypes, PV92 is a simple genetic system that il

Introduction to Stoichiometry
Our on-line Chemistry course covers stoichiometry and demonstrates our scenario based approach to teaching chemistry. Traditional courses tend to follow a bottom-up approach to learning chemistry. This traditional approach teaches abstract concepts and tools before discussing their practical application, which results in students learning bits of unconnected knowledge that are rarely usable let alone memorable. In our approach, scenarios are used both to motivate the material and provide a frame

Whippo Problem Space
What! You haven't ever seen a Whippo? What about a Whammel? Well, how do you think that whales evolved? Which mammals do you think are their closest living relatives? Trying to make sense of whale evolution is a great place to engage in some evolutionary reasoning and look closely at the way scientists work through difficult historical problems. By the way, the term Whippo is used as a sort of shorthand for the hypothesis that whale and hippos represent sister groups—that is, they are each oth
