Homework: Homework will be assigned every week and due the following week in class, except during exam weeks. No late homework will be accepted. Solutions will be posted at the website after submission.
Collaboration Policy: I encourage collaboration on homework assignments: you can learn a lot from working with a group. This means that you are permitted to discuss homework problems with classmates, and are permitted to seek help from other students if you run into difficulties. However, material submitted for grading should represent the work of its author. Any work done in collaboration should be clearly marked as such. Needless to say, it is not acceptable to copy the work of other students, and it is not acceptable for two students to submit identical copies of any part of an assignment (see IIT Code of Academic Honesty for further clarification, http://www.iit.edu/~osa/Handbook/FinePrint.html).
Exams: There will be two midterm exams and a final exam. All exams will be in-class, closed book, and closed class notes, but formulas will be supplied as required (i.e., only lengthy and complicated formulas, not every single formula).
Grading Policy: Homework 20%, Midterm Exam 25% each, Final Exam 30%.
Grade Change Request: If you find that your grades have been added incorrectly, or you would like a grade on your homework or examination reconsidered, you should
-
Prepare a written statement explaining why you think your grade is incorrect;
-
Leave your written request, together with the homework/exam in question in my office at E1-253D or mailbox at E1-247.
Grade change requests should be made within one week after the graded assignment was returned to you.
Attendance: Attendance in my sections of MMAE 202 is rigidly enforced. I will hand out a sheet with each student's name on it. You are required to put your initials in the box corresponding to your name, otherwise you will be marked as absent. The part of my evaluation of your grade will be based upon your attendance record. Therefore, it is imperative that you come to class. If for some reason (and it better be good) you cannot attend class, you must e-mail me the day before and explain why.
ATTENTION:
-
If you can’t here me anytime during the class please warn me to speak louder.
-
If you think that my writing is too small and you can’t read it, please tell me immediately, don't be shy!
-
Please do not hesitate to ask questions anytime during the class, as long as it is not about inter-departmental transfers J.
