Notebook check Course Policies: 1. As in all professional activities, attendance at each scheduled class meeting is 2. 3. 4. 5. 6. 7. 8. mandatory. There will be an attendance sign-in sheet for each lecture period. Students shall notify the lecture/lab instructor prior to the scheduled meeting of unavoidable absences. Quizzes will not be provided to students not attending entire meeting period. Make-up for missed quizzes will not be allowed. Also, there will be no make-up opportunity for any missed activity due to an unexcused absence in lecture, lab or exams. Academic Honesty: Experiments are best done with others as a group. Write-ups will be done as an individual. Failure to observe this directive will result in the penalties outlined in the University policy on academic honesty. You are responsible for making yourself aware of and understanding the policies and procedures in the Undergraduate Catalog (pp. 268-270) that pertain to Academic Integrity. These policies include cheating, fabrication, falsification and forgery, multiple submission, plagiarism, complicity and computer misuse. If there is reason to believe you have been involved in academic dishonesty, you will be referred to the Office of Student Judicial Affairs. You will be given the opportunity to review the charge(s). If you believe you are not responsible, you will have the opportunity for a hearing. You should consult with your instructor if you are uncertain about an issue of academic honesty prior to the submission of an assignment or test. Generally assignments will be due at the beginning of the lab, the week after it is assigned, unless otherwise specified by your lab instructor. Late assignments will not be accepted for credit. There will be no extra credit work for making up of lost grade or poor performance. Your instructor will require access to your computer account at any time for the purpose of evaluating your work. It is mandatory that you provide necessary account information as and when needed to your instructors. No credit will be given for those assignments/activities that cannot be evaluated in set time due to unavailability of your account information from you. Individual instructor shall grade Lab and homework assignments. Each work will be graded out of 10 or 5 points as appropriate. Zero credit shall be assigned to all missed assignments. A minimum grade of 50 % is expected in every Evaluation Item (on earlier page under “Grading”) in order to receive a passing grade in the course. Office hour lab instructors will be announced and posted on their office door (CEAS E-122). During their scheduled office hours, a lab instructor will assist any IME 142 student irrespective of his/her lab section. Students may evaluate their performance based on the scale provided in the syllabus and their own record of individual grades received. Lab instructors do not have the authority to establish individual letter grades. No one can promise you a grade for the course prior to the official grade calculations by the instructor.
