Assignments: It is essential that you study Mathematics several times in a week. The following
assignments will help you with this task.
• Ace my homework – Write my paper – Online assignment help tutors – Discussion Board (20%): on each module, students will participate in a discussion
board involving one or more of the module’s concepts, and a reply to someone else’s
post in a way to show a deeper understanding of the content, or a possible application
of the concepts, if possible. Every week we will have one discussion board with a
minimum of two posts per student. They will be assigned through Blackboard
(elearning.uhv.edu).
• First post to be completed by Wednesday,
• Second post to be completed by Friday.
• Homework assignments (30%): assignment will contain questions that cover basic
knowledge, and also a deeper understanding of the content in theoretical or applied
situations. For each section from the book, we will have one assignment. These
assignments are not timed but will have deadlines. Due Saturdays. They will be on
Webassign (www.webassign.net).
• Midterm (25%): right after week 4, this midterm will cover Modules 1 to 4. It will
have around 50 questions, with questions taken from the same bank of questions as the
modules’ assignments. This test will be timed: 2 hours to complete it. Due Sunday
after Module 4. It will be on Webassign (www.webassign.net).
• Final exam (25%): Similar to midterm, it will be on week 8. It will not be
cumulative. It will cover modules 5-7. It will be on Webassign (www.webassign.net).
There will be no make-up activities, unless there is an emergency, in which case a written
justification will be required. If you miss an activity, you will automatically receive zero.
Grade distribution: (the instructor reserves the right to modify these bounds only to benefit students, in other
words, the “cutoff” for some letters may be slight less than what is described here).
A: 90 – 100 B: 80 – 89 C: 70 – 79 D: 60 – 69 F: below 60
Curves on Grades: The instructor will not make any curves on grades.
Blackboard use: We will use Blackboard and the Webassign system.
Announcements, syllabus, calendars, and more will be available on
Blackboard: https://elearning.uhv.edu
Important: Computer Science and Math majors must receive a grade of C or higher in all
Computer Science and Math courses used as prerequisite or transferred from other institutions.
Any such course in which a student received a D, F, or W must be repeated.
Netiquette: Use the following rule of thumb “if you wouldn’t do or say something in real life,
don’t do it online either.
1. Before posting your question to a discussion board, check if anyone has asked it
already and received a reply.
2. Stay on topic, don’t post irrelevant links, comments, thoughts, or pictures.
3. Don’t type in ALL CAPS! If you do, it will look like you’re screaming.
4. Don’t write anything that sounds angry or sarcastic, even as a joke, because without
hearing your tone of voice, your peers might not realize you’re joking.
5. Always remember to say “I need help writing my essay – research paper” and “Thank you” when soliciting help from your
classmates.
6. Respect the opinions of your classmates. If you feel the need to disagree, do so
respectfully and acknowledge the valid points in your classmate’s argument.
Acknowledge that others are entitled to have their own perspective on the issue.
7. If you reply to a question from a classmate, make sure your answer is accurate! If
you’re not 100% sure when the paper is due, DO NOT GUESS! Otherwise, you could
really mess things up for your classmates and they will not appreciate it.
8. If you ask a question and many people respond, summarize all answers and post that
summary to benefit your whole class.
9. Be brief. If you write a long dissertation in response to a simple question, it’s unlikely
that anyone will spend the time to read through it all.
10. Check the most recent comments before you reply to an older comment, since the
issue might have already been resolved or opinions may have changed.
11. Run a spelling and grammar check before posting anything to the discussion board. It
only takes a minute and can make the difference between sounding like a fool and
sounding knowledgeable.
STANDARD UHV COURSE POLICIES:
Academic Integrity: “Students. . . have a responsibility to fulfill, and indeed an investment to protect, in helping to
ensure that academic achievement is characterized by honesty and fair play” (UHV Student Handbook). The
University takes academic integrity very seriously. It is your responsibility to understand what behavior violates
academic honesty rules and to understand the consequences for such violations. I need help writing my essay – research paper refer to the UHV Student
Handbook: https://www.uhv.edu/handbook/academic-honesty-policy/
Plagiarism: Plagiarism is an increasingly common form of academic misconduct. All of the following are
considered plagiarism:
• turning in someone else’s work as your own
• copying words or ideas from someone else without giving credit
• failing to put a quotation in quotation marks
• giving incorrect information about the source of a quotation
• changing words but copying the sentence structure of a source without giving credit
• copying so many words or ideas from a source that it makes up the majority of your work, whether
you give credit or not.
Most cases of plagiarism can be avoided, however, by citing sources. Simply acknowledging that certain material
has been borrowed and providing your audience with the information necessary to find that source, is usually
enough to prevent plagiarism.
