And so the term begins, as does version 1.0 of my Coevolutionary Interactions course (bio3401). The idea behind the course is to use species interactions and the coevolutionary process to reinforce key theory/ideas in evolution and ecology. To do that, I am taking a case studies approach where I give an interactive lecture on a new topic each week, including key background information students need to put the papers they will read into context. I then assign two papers from the primary literature on the topic, and ask a group of students to lead discussion about the papers during the following class. I have not taught a course in this format before, so will blog again at the end of the term and let you know how it goes.
For now, after rearranging post-it notes ad nauseam, I have decided on the following topics and associated readings:

(11) Lecture on coevolution within communities, and ecosystem stability.
Finally, for the assessment I’ve decided to model these on my two favorite courses of all times: a) Janis Antonovics Disease course at UVA, where we all had to make posters about a given disease, and b) Curt Lively’s Evolution course at Indiana University, where the final exam was 5 short answer questions verbatim from a list of 20 he had given us weeks before.
Oh yes, and I am also striving to have at least one bit of maths in every lecture! Luckily, I’ve got a great group of (32) students who are already showing full engagement and enthusiasm for the subject. Looking forward to a busy but fun term!
