Homework: All homework must be completed in a neat an organized manner. Due dates for homework problems will be announced in class. No credit will be given for late homework.
Lab Reports: Each student will prepare a lab report after the completion of lab experiments. Reports are due one week after the experiment. No late report will be accepted.
Collaboration Policy: I encourage collaboration on homework and lab assignments: you can learn a lot from working with a group. This means that you are permitted to discuss homework problems and lab results 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 one midterm exam and a final exam. All exams will be in-class, closed book, and closed class notes, but formulas will be supplied as required.
Grading Policy: Homework 15%, Lab Reports 30%, Midterm Exam 20%, Final Exam 35%.
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 received later than one week after the graded assignment was returned to you will not be considered.
Attendance: Attendance in MMAE 536 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 you cannot attend class, please e-mail me the day before and explain why.
