Disabled Applicants and Students Daniel Webster College is committed to compliance with Section 504 of the Rehabilitation Act of 1973 and its regulations. The school does not discriminate on the basis of disability in admission or access to, or treatment or employment in, its programs and activities. The school's student disability coordinator coordinates Section 504 compliance. Applicants or students with a disability may request an accommodation by contacting Kathy Hipp, Associate Dean of Arts and Sciences, at 603-577-6659 or hipp@dwc.edu; or by contacting the Office of Academic Affairs: https://studentportal.dwc.edu/Pages/HelpCenter.aspx Academic Honesty Intellectual curiosity is at the heart of the academic enterprise. Students, faculty and administration at Daniel Webster College consider such violations as cheating and plagiarism to be so unethical as to call into question whether the violator should continue as a member of the College community. Transcripts that misrepresent academic performance not only endanger students’ chances for success in their careers but also damage the integrity and reputation of the institution. Student Honor Pledge Daniel Webster College believes that all students have the right to learn in an academic community that insures fair competition, and respects truth and honesty. Academic dishonesty is not tolerated at Daniel Webster College. The Student Honor Pledge is intended to create a community of fairness, respect and responsibility in the pursuit of academic enterprise. All students are expected to abide by the Student Honor Pledge. I pledge on my honor, as a student at Daniel Webster College, that I have neither given nor received any unauthorized aid on this assignment/examination. For more information regarding Daniel Webster College’s ethical standards, please refer to the current college catalog. Grading Scale The following scale is based on the grading structure outlined in the Daniel Webster College catalog and is used to assign letter grades: A = 93+ C+= 76-79 A- = 90-92 C = 70-75 B+= 87-89 D = 65-69 B = 83-86 F = Below 65 B- = 80-82 Daniel Webster College 2 Expectations Homework problems from the text will be assigned on a regular basis and are subject to change. A limited number of other assignments not in the text might be given as supplemental exercises. It is expected that the interested student will endeavor to solve these problems. Remember that you cannot adequately learn this material without practicing the methods. Talk to me in advance if you have reasonable reason(s) for not being able to turn in your homework or any assignment on time. To be fair to all students, late homework or other assignments are given a 33% reduction in points per day that the homework / assignment is late. A “day” is defined as 24 hours, beginning at the start of class time. In addition, there will be a series of three (3) analysis and programming projects assigned which will utilize commercial software. In support of the student evaluation process, there will be two (2) exams, and one (1) comprehensive final exam. No make-ups for exams will be given unless satisfactory advanced notice and reason is supplied to the instructor. The grades will not be curved. The grades will be assigned based on the absolute grade scale shown above. Active class participation is expected. In this course you will be expected to act in a professional manner. Among other things, this includes showing up on time prepared for the task at hand. This shall include not just being on time for class, but also for any and all additional outside meetings you will have with group work. You will be expected to read assigned chapters/tutorials before coming to class and be ready to actively participate. Classroom activities such as chatting, use of computer, ipod, cell phone and other electronics are not allowed. In addition, eating in class is not allowed. Students may ask questions of one another when working on out-of-class assignments. However, each student/team must do their own work. A first occurrence of academic dishonesty will result in a zero for that assignment for all who are involved. A second occurrence will result in an F for the course. Note that all such occurrences must be reported in writing to the Chief Academic Officer who may prescribe additional penalties.
