EEB 2245: Each half of the course counts for 50% of your lecture grade. Your grade in the first half of the course will be based on your performance on two lecture exams (for a total of 200 points). Your grade in the second half of the course will be based on your performance on three lecture exams (180 points total) and weekly, short on-line quizzes (20 points) (for a total of 200 points). However, your grade for Exams1–4 will be dropped. Please note: because you are allowed to drop one of these grades, we will not give make-up exams.

EEB 2245W: For W students your final grade in the lecture portion of the course will be calculated as above. This grade will constitute 75% of your final course grade. The W portion of the course, as determined by your “W” instructor, will constitute the remaining 25% of your final course grade. Please note that an F in either the W or lecture portion of the course will result in an F for the entire course. Dr. Paul Lewis (TLS 162; tel: 486–2069; paul.lewis@uconn.edu) is the coordinator of the W portion of the course. Refer to HuskyCT for further information on the W portion of the course. You will be assigned your W instructor at the mandatory library session you attend for the W portion of the course. You must sign up for a library session in HuskyCT by January 19th.

Lecture Schedule

Please read assigned chapters, as indicated below, prior to class
This schedule is subject to change. Check regularly for updates!

* Registrar’s office note: Students are required to be available for final exams during the time stated in the Registrar's Office Schedule. If you have a conflict with this time you must visit the Office of Student Services and Advocacy to discuss the possibility of rescheduling your final exam. Please note that vacations, previously purchased tickets or reservations, graduations, social events, misreading the assessment schedule and over-sleeping are not viable excuses for missing a final assessment. If you think that your situation warrants permission to reschedule, please contact the Office of Student Services and Advocacy to meet with a staff member.
