CLASS PREPARATION

The student is expected to keep up with the daily reading assignments and to do all of the assigned homework problems.  The students must solve at least two or three problems assigned from each lecture.  Every Monday one or two problems will be selected from the previous week to be graded and the solutions to all the homework problems will be posted on the course web site.  Late homework will not be accepted except for a valid emergency.  All homework assignments are to be done neatly, in pencil, on 8½X11 papers with your name. Direct copying of homework of any kind is never acceptable. See Plagiarism Policy at: http://www.egr.msu.edu/me/files_me/forms/Plagiarism%20Policy1.pdf

 

TESTS AND FINAL EXAMINATION

Make-up tests for students with an excused absence must be arranged prior to the test date. The tests and final exam will be open book.

 

ACADEMIC HONESTY

Article 2.3.3 of the Academic Freedom Report states that "The student shares with the faculty the responsibility for maintaining the integrity of scholarship, grades, and professional standards." In addition, the ME Department adheres to the policies on academic honesty as specified in Protection of Scholarship and Grades; the all-University Policy on Integrity of Scholarship and Grades; and Ordinance 17.00, Examinations. (See Spartan Life: Student Handbook and Resource Guide and/or the MSU Web site: www.msu.edu.) Students who plagiarize may receive a 0.0 on the assignment or fail the course or receive more severe sanctions.
