The course, assignments, and grading

Embryology 1480 is intended to raise (if not answer) the fundamental question of where babies come from. In addition, I would like to entertain possibilities for embryonic stem-cell therapy and human evolution. I have chosen a new edition of an old textbook (Moore and Persaud) that is fairly current  (i.e., 7th edition). I also plan to make the lectures more current by dividing them into three parts: the first (Monday) will be rooted to human embryology (hence dependent on the textbook); the second (Wednesday) will provide a working knowledge of animal embryology, and the third (Friday) is intended to serve as an introduction to developmental biology with all its fascinating questions about regeneration, repair, restoration and, consequently, enhanced longevity.

So what do you have to do to get an A (or any other grade) in this course? There would seem to be three parts to the process: writing, exams, and a bonus for attendance.

First of all, the course is a W course, which means that you have to write a total of no less than 24 pages. You can do this in either of two ways:

(1) You may write a weekly journal entry summarizing the textbook and/or lectures, raising questions or answering them, that you will submit to me via e-mail, and I mean WEEKLY!  I will read your journal entries, edit them, and send them back to you via e-mail for revision, if necessary. Your revised entries will be graded on the basis of clarity and content.
(2) You may write a term paper based on the primary (i.e., research) literature ((see "Topics for Papers" by following the links at my web site: www.pitt.edu/~sshostak) of no less than 8 pages that you will submit to me at least twice for editing and revision. Your final version will be graded on the basis of cogency and clarity. I also require a hard copy of the literature you are reviewing, although your paper may be transmitted via e-mail.

Second, two hour exams will be given during class time (see schedule below) and a final during finals' week. Students can take two hour exams or one hour exam and the final. In other words, if you take both hour exams and you're not satisfied with one of your grades, you can take the final.

As for the bonus for attendance: I will take attendance at each lecture and give a 10 percent bonus for perfect attendance (prorated for less than perfect).

I urgently recommend that students see me at least once to discuss their journal entries, the outline for their paper or anything else they may like to discuss. Please make an appointment by initialing the schedule posted outside my room (146 CRW), by sending me e-mail (click  here) or just asking. I'll try to be available at the date and time you choose to see me, but  conflicts will have to be resolved by negotiation and compromise.

Of course, I will accommodate students with any sort of disability, and I will make adjustments for religious holidays.
