MWF 12:00 Ð 1:00, Parker 104

 

Office hours 

My official office hours are Monday 10-12 and 1-2, and Thursday 10-11 and 12-2.

I will be happy to arrange for a different time to meet with you. To do that you can stop by my office and leave a note if IÕm not there, send me an email, or leave me a telephone message.

Office 230 Parker Hall; email zpasman@ic.edu; phone 245-3435.

Assignments

There will be two take-home exams (dates indicated on the syllabus).  In addition, students will take turns presenting research papers throughout the semester.  Exams will account for 40% of the final grade and presentations for 40%.  Every student is expected to be able to discuss each paper, irrespective of the presenter.  Students who are not presenting are required to submit 3 questions about the paper (ideally, one question each from the Introduction, Results, and Discussion sections).  These questions will account for 20% of the final grade.

 

Grading

         90-100%  A

         80-89%    B

         70-79%    C

         60-69%    D

        

I do not anticipate using a curve, but I will do so if necessary.  Ò+Ó and Ò-Ò grades can be assigned.

 

Attendance

You are expected to attend lectures regularly and contribute to discussions.  Remember that material on the exams will be drawn heavily from the material covered in class.  Also, remember that a large amount of your final grade depends on class discussion, which usually cannot be accomplished without regular attendance.

 

Academic Honesty

I will prosecute any case of academic fraud or dishonesty that I can document.  Academic dishonesty, simply put, is representing work as your own when it is not.  Also, please see the Illinois College Honor Code.  If, in your judgment, an issue might be subject to academic honesty considerations, ask me for clarification as soon as possible.
