ALL ASSIGNMENTS THAT ARE NOT AUTO-GRADED VIA CANVAS (E.G., FINAL EXAM OR DISCUSSION AREA POSTS) ARE EXPECTED TO BE SUBMITTED VIA CANVAS USING FILE ATTACHMENTS. PLEASE MAKE YOURSELFS FAMILIAR WITH USING PROGRAMS SUCH AS: MS Word (.doc files), Adobe Acrobat (.pdf files), and any commercial screen shot software (i.e., Snapz Pro, Screencatcher, etc.). THIS IS A MUST FOR THIS CLASS, CONTACT THE INSTRUCTOR IF YOU DO NOT UNDERSTAND THIS POLICY OR NEED ASSISTANCE.

FILE NAMING CONVENTION FOR SUBMITTING ASSIGNMENTS:

PLEASE USE THE FOLLOWING NAMING CONVENTION WHEN SAVING AND EMAILING COMPLETED ASSIGNMENT FILES:

lastnamefirstinitial.suffix

For example, for myself I would name my first homework assignment file:

krosjhomework#1.doc

Be forewarned, I will either send your assignments back to you ungraded or downgrade your work if you do not follow this naming convention.

Homework will be assigned according to the tentative schedule presented. Please attempt every problem and feel free to ask me or your fellow students for assistance. However, all homework turned in must be your own work and missed assignments will receive a zero grade. Late homework will not be accepted.

The case study assignments on the area of materials management. You will receive more information on the content and format of the case studies early in the term.

Exams will cover material from the online video lectures and in class examples. The problems on the exams will be similar to the homework problems. Missed exams will receive a zero grade. Please make prior arrangements if the exam will be missed.

Final grades will be assigned by letter and will be derived approximately from the grading percentages shown above roughly following the standard +/- scale. I will assign grades on individual assignments according to the ECU +/- scale (A = 4.0, A-=3.7, B+=3.3, B = 3.0, B-=2.7, C+=2.3, C = 2.0, C-=1.7, D+ = 1.3, D = 1.0, D- = 0.7, F = 0.0).

Roughly the following grade cut-offs will be used: above 3.7 = A, above 3.3 to 3.7 = A-, above 3.0 to 3.3 = B+, above 2.8 to 3.0 = B, above 2.5 to 2.8 = B-, above 2.2 to 2.5 = C+, above 1.9 to 2.2 = C, above 1.6 to 1.9 = C-, above 1.3 to 1.6 = D+, above 1.0 to 1.3 = D, above 0.8 to 1.0 = D-, below 0.8 = F. Percentage scores will not be assigned.

Attendance: I will not be taking attendance, but attending class will help immensely in garnering the maximum grade in the course.
