Course Policies: Laptops and other electronic devices (except calculator) are not permitted during lecture. Cell phones should be turned off during class. Homework assignments are due before start of class. Late homework submissions are not accepted. Makeup exams and homework are not allowed (Exceptions for emergences with official documents). Students arriving late to an exam or quiz will not be allowed to take it. Quizzes can be unannounced. It is students responsibility to check their email and Catcourse for any course announcements or material on timely manner. Assigned reading material is mandatory and can be the subject of a quiz even if we did not cover it in class yet. Late arrivals and early leave will be considered as absence. Insufficient attendance will lead to an F grade. You may discuss homework problems with your classmates, but you are responsible for your own work. You are encouraged to read the sections in the textbooks related to the covered topics prior to the lecture as well as after. If you miss a class due to personal emergency or medical reasons, please be sure to inform the instructor by e-mail. After an assignment grade has been posted online, students must see the instructor within one week if they wish to discuss the assignment and their work. University's rules on academic honesty concerning exams and individual assignments will be strictly enforced. Dishonesty Statement: Disability Statement: a. Each student in this course is expected to abide by the University of California, Merced's Academic Honesty Policy. Any work submitted by a student in this course for academic credit will be the student's own work. b. You are encouraged to study together and to discuss information and concepts covered in lecture and the sections with other students. You can give "consulting" help to or receive "consulting" help from such students. However, this permissible cooperation should never involve one student having possession of a copy of all or part of work done by someone else, in the form of an e mail, an e mail attachment file, a diskette, or a hard copy. Should copying occur, both the student who copied work from another student and the student who gave material to be copied will both automatically receive a zero for the assignment. Penalty for violation of this Policy can also be extended to include failure of the course and University disciplinary action. c. During examinations, you must do your own work. Talking or discussion is not permitted during the examinations, nor may you compare papers, copy from others, or collaborate in any way. Any collaborative behavior during the examinations will result in failure of the exam, and may lead to failure of the course and University disciplinary action. Accommodations for Students with Disabilities: The University of California Merced is committed to ensuring equal academic opportunities and inclusion for students with disabilities based on the principles of independent living, accessible universal design and diversity. I am available to discuss appropriate academic accommodations that may be required for student with disabilities. Requests for academic accommodations are to be made during the first three weeks of the semester, except for unusual circumstances. Students are encouraged to register with Disability Services Center to verify their eligibility for appropriate accommodations.
