This class will be conducted in the traditional format of face-to-face lectures. When taking this class, students must:

• attend the class, as scheduled;
• actively participate in class work;
• prepare assigned reading;
• submit assigned homework;
• take and pass all the in-class quizzes and the final exam.

Make-up tests will be given only for documented emergencies, and then only at the instructor's discretion and convenience. However, if you have a good reason, please do ask for consideration.

The class will be conducted in real time, face-to-face, in the format of a traditional lecture,

You are expected to attend every class session. You are responsible for all that transpires in class (including content, course requirements, tests and assignments) whether or not you are in attendance, even if your absence is the result of late registration, add/drop activity at the beginning of a term as permitted by College policy, or religious observance.

Arriving late, leaving early or taking unreasonably long breaks counts as partial absence.

The College defines excessive absence or lateness as more than the equivalent of one week of class meetings during the semester. Excessive absence or lateness may lead to failure in, or removal from, the course. You may be required to drop or withdraw from this course when, in the judgment of the instructor, your absences have been excessive.

In accordance with the New York State Education Law §224-a, any student who is unable to register or attend class on a particular day because of religious observance will be excused from any examination, study or work requirement scheduled for that day. Students must notify the professor, via College email (or otherwise in writing), at least one week prior to their absence due to a religious observance. In that case, students shall be given an equivalent opportunity to make up any examination, study, or work requirements within a reasonable amount of time of the religious observance. Please refer to the Religious Observance Policy for additional information.

Disruptive behaviors, as defined by the Student Handbook, will not be tolerated. In case of violations, the college policy allows the instructor "to remove a student from a class for one class meeting, and, in those cases where the continued presence of the student poses a substantial threat or would be disruptive to the class, request that the Associate Dean of Student Services impose an interim suspension pending a disciplinary hearing."

Suffolk County Community College provides students with the opportunity to demonstrate their knowledge by submitting coursework that is uniquely theirs and giving proper attribution to the work of others. Participating honestly in the SCCC academic community ensures that students can take pride in their education and their contributions to scholarship. Without academic integrity, students gain unfair advantage over others and prevent their own intellectual progress. As a student in this class, you are expected to uphold the SCCC core value of integrity and understand the Special Procedures for Academic Dishonesty (section P. starting on page 23 of the Student Code of Conduct). Specifically, when academic integrity is violated, the college policy allows the instructor to "initiate student conduct action through the Campus Associate Dean of Student Services. The faculty member may impose any of the following penalties: require that the student repeat the assignment or the exam; give the student a failing grade for the assignment or exam; or give the student a failing grade for the course. Should the student believe that s/he has been wrongly or unfairly accused of academic dishonesty, the student shall have the right to pursue the matter though the Course Grade Grievance Procedure."

The Code prohibits academic misconduct, which includes any action that results in students giving or receiving unauthorized assistance in an academic exercise, or receiving credit for work that is not their own. Academic exercise includes all forms of work submitted for credit. Academic misconduct includes, but is not limited to, the following behaviors:

• cheating — unauthorized use of textbooks, notes, mobile devices, artificial intelligence tools or any other sources;
• plagiarism — use of another person's work or ideas without crediting them, including using material generated by artificial intelligence tools for an assignment without instructor authorization;
• complicity — giving help to, or receiving help from, someone engaged in academic misconduct;
• multiple submissions — submitting the same work for credit in more than one course without the instructor's permission;
• falsification and forgery — making up information or falsifying your own or someone else's identity.

Information about the Student Code of Conduct, plagiarism and the citation process can be found on the Academic Integrity Procedures webpage. To learn more about academic integrity, college policies and expectations in this area, and proper ways to avoid possible violations, see the Academic Integrity and Plagiarism Guide.

Suffolk County Community College provides reasonable accommodations to registered students with disabilities who have self-identified and been approved by the Office of Disability Services. Once approved for reasonable accommodations, such students will be provided with an Accommodation Letter, describing the specific accommodations. Students must present this letter to each of their professors before accommodations can be provided.

Students who have, or think they may have, a disability are invited to contact Office of Disability Services for a confidential consultation. You can call the Office at (631) 851-6355, contact it via email disabilityG@sunysuffolk.edu, or stop by to make an appointment in Caumsett Hall, Lower Level, Room 20.
