Grading Policy

From the Wilmington College Faculty Handbook:

It is the policy of Wilmington College to strive for fairness in grading and avoid grade inflation. Faculty are encouraged to regard "C-" as a satisfactory grade, which means the student is meeting College standards, and will treat it as such in talking with students, unless otherwise noted in the College Catalog. The grade "A", on the other hand, should mean outstanding achievement, with a grade of "B" in between. The grade "D" represents minimally acceptable achievement, and the grade "F" indicates failure.

 A = 100 - 96A- 95.9 – 91
B+ = 90.9 – 88B = 87.9 - 85B- = 84.9 – 82
C+ = 81.9 – 79C = 78.9 – 76C- = 75.9 – 72
D+ = 71.9 – 69D = 68.9 - 66 
 F = BELOW 66 

Instructor Course Policies

Instructor's Course Attendance Policy
  • Attendance is required for all class weeks. Students must demonstrate that they are actively participating in the course by submitting required assignments and attending scheduled physical classroom sessions.
  • If you are sick or do not feel well, do not come to class if you are sick! Please email the instructor prior to class.
  • You are expected to be in class, on time, every time.  If you miss more than 3 lectures for reasons other than illness, emergency, or other excused absences approved by the instructor, your final grade will be reduced one letter grade for each day missed.  NO UNEXCUSED ABSENCES FROM LABS
  • You are responsible for communicating with the instructor about completing missed work
  • The opportunity to makeup missed work may be given only if the absence is excused
  • See the current Student Handbook for the College’s Attendance policy especially as it pertains to excused absences.
  • If you are absent due to athletics, field trip, or other event where you officially represent the College, please email the instructor at least one week prior to the event.  Understand that although these are excused absences, you can only complete missed work IF you let the instructor know ahead of time.
  • If absent due to illness or emergency, contact the instructor as soon as you can
  • Exams, quizzes, & assignments missed due to unexcused absences will receive a 0 when calculating your final grade
Instructor's Academic Integrity Policy
  • You are expected to read the assigned material and be prepared for discussion on the material. As a general rule, you should have the reading done for the week at the beginning of the assigned week.
  • Wilmington College and federal financial aid authorities require that students commit a minimum of two hours of time per week outside of class for each hour of time they are in class.
  • You are responsible for the materials in lecture and in all assigned reading

Academic Integrity

  • Absolute honesty is expected.  Cheating, plagiarism, lying, or disrespect for other students or the instructor will not be tolerated by the instructor or the College.
  • Unless asked to use artificial intelligence (AI) apps such as ChatGPT to help you complete an assignment, all work (essays, test answers, homework answers, etc.) that you submit in this course must be originally produced by you and not by AI. Failure to comply with this policy will result in penalties for academic dishonesty (see below).
  • Plagiarism will not be tolerated.  All references should be provided, if in doubt, provide a reference (this includes works produced with the assistance of AI).
  • Academic dishonesty is not acceptable.  Assignments, which are plagiarized, will not be accepted and will receive the grade of zero. Cheating on a test or quiz will also receive a grade of zero.
  • Penalties for plagiarism or cheating in this class may range from a zero on the assignment to an F in the class. In addition, all cases will be reported in writing to the Office of Academic Affairs.  In the case of serious infractions, the Academic Standards and Appeals Committee may take further action.
  • “See the current Student Handbook for the college’s Academic Integrity policies as they pertain to examinations, plagiarism, classroom behavior, and the process for handling academic misconduct charges.”

Taking an Online Exam or Quiz:

Cheating is a serious offense and subject to disciplinary action. Some examples of this offense are:

  • Any copying or recording of the exam/quiz questions or answers, including taking screenshots, pictures, or video, and disseminating them to anyone before or during the exam.
  • Opening browsers and searching for content.
  • Using mobile devices/smart phones, other web browsers, software, or other computers during the exam/quiz.
  • Bringing in resource materials other than those allowed (e.g., calculator).
  • Allowing other individuals to come in and out of the room during the exam.

Plagiarism Policy:

Plagiarism is defined as the representation of another’s words, ideas, concepts, research, or creative production without proper attribution whether intentional or unintentional. It is the student’s responsibility to be informed about what constitutes plagiarism. Plagiarism can occur in the submission of one’s own work or in work submitted by a group.

Examples of plagiarism include the following:

  • Paper(s), information, quiz & test answers, homework assignments, etc. created by AI apps such as ChatGPT
  • The submission of a paper not one’s own, including turning in a paper that has been purchased from a commercial research firm or obtained from the internet
  • Copying word for word information without quotation marks
  • Paraphrasing information (that is, the use of one’s own words with only minor changes to the original)
  • Use of information not considered general knowledge without proper citation
  • Listing of misleading or false sources on a reference page
  • The use of a paper or project for one course that was previously submitted for another course, either at Wilmington or at any other institution

Plagiarism is a serious academic offense and carries serious academic consequences. Violations will be recorded by the Associate Vice President of Academic Affairs at the Main Campus and Vice President of External Programs at the Cincinnati Branch Campus.

When an instructor discovers plagiarism, the instructor will first consult with the Associate Vice President of Academic Affairs if a main campus student, or the Vice President for External Programs if a branch campus student, in order to determine if the student is a first-time offender. For first offenses, the instructor has the ability to determine the penalty for the offense. Students with academic integrity violations may not be eligible for academic awards and honors (i.e., Academic Honors, Dean’s List/Merit List, Green Key Honor Society, Quaker Impact Award, and other Honorary Societies). For a second offense or more, the Associate Vice President of Academic Affairs at the Main Campus or the Vice President for External Programs for students at the branch campus, will report the offense to the academic standards and appeal committee and gather evidence for a hearing with the student. It is possible that the student will receive a substantial reduction in grade for the course or will fail the course. Multiple instances could even lead to suspension or expulsion from Wilmington College.

There are many university, college and private websites students may consult about how to avoid plagiarism. Sites with particularly helpful suggestions can be found at:

Electronic Device/Texting Policy

  • You need to focus on the materials we are discussing in class.  The use of electronic devices is distracting and limits your ability to stay focused in class.  Other than a computer you bring to class for taking notes, do not use these devices in class.  Also, stay on task with your laptop computer.  Do not surf the web, text, etc. when you should be learning the material.
  • Repeated violations of this policy may reduce your next grade 10% (e.g., if you earned a 70% on the next exam, your grade would be reduced to 60%)

WC Blackboard

Use (wc.blackboard.com)

  • May be used for: quizzes & exams, lecture outlines, assignments, instructions, due dates, readings, posting grades

Communicating with the Instructor

Email & Video Conferencing Etiquette

Email

  • When communicating via email, there are some important guidelines to follow:
  • Think of your email as a professional, business communication. Include an informative subject line.
  • Make sure that your email is grammatically correct. You should think about your email as a chance to show your instructor that you care about the class, and that you are willing to take the time to proofread your message before sending it.  Keep your tone friendly and respectful and keep your emails concise and to the point.

Video Conferencing

If you attend class via Zoom, below are a few things to keep in mind:

  • Requests to attend class via Zoom for reasons other than illness or emergency must be approved by the instructor at least 1-day in advance.  If the reason is due to sudden illness or emergency contact the instructor as soon as you can.  Requests will be honored if the reason for attending class fits within the College’s Attendance policy in the Student Handbook (i.e., illness, emergency, approved excused absences).  I overslept or do not feel like getting out of bed are not valid reasons for attending class via Zoom.
  • Consider your appearance on the webcam. The less seriously you take the video conference, the harder it will be to learn the material or participate in the class.
  • Consider what is in the background of your video. Nothing is more embarrassing than an awkward or inappropriate poster or item in your background. A blank background is easiest to work with but be considerate.
  • Remember that a video conference has the same degree of respect as a live class. You would not randomly call out or fall asleep during class (let’s hope!), so please continue that respect on the webcam.
  • Keep your video on.
  • Unless you are speaking keep the mute on. This will avoid background noises.

Institutional and Program-Level Policies

Final Exam Schedule

All exams will follow the Final Exam Schedule. Students scheduled to take three or more final examinations on one day may request to arrange their examination schedule, so no more than two exams occur on one day.
Requests for early or late exams are considered only under extreme circumstances. Prior to the exam period, the student must file a written request on the Early/Late Exam Form available in the Student One Stop Center, Academic Records, and on the WC portal. The form must be signed by the Instructor and the Academic Dean, approving the alternate exam time. This process must be completed prior to the scheduled exam period.

Out-of-class Work Expectation

A minimum of 2 hours of out-of-class student work is expected for each hour of in-class time for traditional face-to-face courses. For online and hybrid courses, the combination of face-to-face time and out-of-class work should be equal to 3 hours per credit hour per week.
