Students are expected to work in groups for the lab portion of the course. All group members are expected to design, build, and troubleshoot their own circuits and to actively contribute to the completion of projects and other assigned tasks. 3- As a courtesy to your classmates and to me, Please turn off all cellular phones, blackberries, iPods, and pagers when you come to class or lab, unless you are expecting an emergency call. Please refrain from spending your valuable class time exploring the internet, checking your email, etc. on the computer at your station! 4- Homework will be assigned every class and collected at the next class meeting, unless otherwise announced. Lab reports will be due at the beginning of the next scheduled laboratory session – no late homework or lab reports will be accepted! Homework solutions must be submitted on Engineering paper. 5- 6- Homework problem submission guidelines and grading procedure: a.) Start each Problem on a new sheet of paper. b.) Identify the Problem (Problem #1.6). c.) Sketch the circuit diagram, list the given information, and indicate what you are solving for. d.) Show all of your reasoning and work! e.) Highlight the answer by underlining or enclosing in a box. f.) Be neat! If your work is messy and unreadable, it will be returned to you with a grade of 0! g.) Each problem will be worth 15 points. Neatness and presentation together are worth 5 points. Technical procedure, reasoning, and correct answers are worth the remaining 10 points. Don’t be afraid to ask a question in class! If you are having difficulty understanding something, someone else is most likely having the same difficulty! 5 7- Don’t be hesitant to come to my office for help. If additional time is needed to help you, we can make a special appointment. 8- Exams will be given as announced in class – failure to take an exam when scheduled will result in a grade of 0 for that exam! 9- Exams are “closed book”. Each student will be allowed to bring one standard 8 ½ by 11 inch sheet of paper with anything they want written on it to each of the exams. These sheets may accumulate for the final exam. 10- Each student must use their own pencil(s), erasers, calculators, etc.! No borrowing or sharing! 11- Please, no food or drinks in the classroom. This policy must be strictly enforced. Please use the lounge areas near the vending machines or room II-218. 12- Last, but not least, please consult the undergraduate catalog, student handbook, or the web site http://www.umassd.edu/studenthandbook/academicregs/ethicalstandards.cfm to review the university’s policy on academic dishonesty and plagiarism. 6
