7 Columbia College Online Campus P a g e 7 Course Policies Student Conduct Plagiarism All Columbia College students, whether enrolled in a land-based or online course, are responsible for behaving in a manner consistent with Columbia College's Student Conduct Code and Acceptable Use Policy. Students violating these policies will be referred to the office of Student Affairs and/or the office of Academic Affairs for possible disciplinary action. The Student Code of Conduct and the Computer Use Policy for students can be found in the Columbia College Student Handbook. The Handbook is available online; you can also obtain a copy by calling the Student Affairs office (Campus Life) at The teacher maintains the right to manage a positive learning environment, and all students must adhere to the conventions of online etiquette. Your grade will be based in large part on the originality of your ideas and your written presentation of these ideas. Presenting the words, ideas, or expression of another in any form as your own is plagiarism. Students who fail to properly give credit for information contained in their written work (papers, journals, exams, etc.) are violating the intellectual property rights of the original author. For proper citation of the original authors, you should reference the appropriate publication manual for your degree program or course (APA, MLA, etc.). Violations are taken seriously in higher education and may result in a failing grade on the assignment, a grade of "F" for the course, or dismissal from the College. Collaboration conducted between students without prior permission from the instructor is considered plagiarism and will be treated as such. Spouses and roommates taking the same course should be particularly careful. All required papers may be submitted for textual similarity review to Turnitin.com for the detection of plagiarism. All submitted papers may be included in the Turnitin.com reference database for the purpose of detecting plagiarism.

Non-Discrimination There will be no discrimination on the basis of sex, race, color, national origin, sexual orientation, religion, ideology, political affiliation, veteran status, age, physical handicap, or marital status. Disability Services Students with documented disabilities who may need academic services for this course are required to register with the Coordinator for Disability Services at (573) Until the student has been cleared through the disability services office, accommodations do not have to be granted. If you are a student who has a documented disability, it is important for you to read the entire syllabus before enrolling in the course. The structure or the content of the course may make an accommodation not feasible. Online Participation You are expected to read the assigned texts and participate in the discussions and other course activities each week. Assignments should be posted by the due dates stated on the grading schedule in your syllabus. If an emergency arises that prevents you from participating in class, please let your instructor know as soon as possible. Attendance Policy Attendance for a week will be counted as having submitted a course assignment for which points have been earned during that week of the session or if the proctoring information has been

8 Columbia College Online Campus P a g e 8 submitted or the plagiarism quiz taken if there is no other assignment due that week. A class week is defined as the period of time between Monday and Sunday (except for Week 8, when the week and the course will end on at midnight). The course and system deadlines are all based on the Central Time Zone. Cougar All students are provided a CougarMail account when they enroll in classes at Columbia College. You are responsible for monitoring from that account for important messages from the College and from your instructor. You may forward your Cougar account to another account; however, the College cannot be held responsible for breaches in security or service interruptions with other providers. Students should use for private messages to the instructor and other students. The class discussions are for public messages so the class members can each see what others have to say about any given topic and respond. Late Assignment Policy An online class requires regular participation and a commitment to your instructor and your classmates to regularly engage in the reading, discussion and writing assignments. Although most of the online communication for this course is asynchronous, you must be able to commit to the schedule of work for the class for the next eight weeks. You must keep up with the schedule of reading and writing to successfully complete the class. Late homework assignments will not receive credit. Discussion postings will not be accepted late. I suggest that you plan ahead and do not wait until the last minute as you may encounter technical problems that could result in not getting the assignment in on time. If you encounter a technical problem in sending in your assignment you will need to overcome it within the time frame that the assignment is due. Course Evaluation You will have the opportunity to evaluate the course near the end of the session. Course evaluations will open on Sunday of Week 5 and will remain open until Thursday of Week 7. A link will be sent to your CougarMail that will allow you to access the evaluation. Be assured that the evaluations are anonymous and that your instructor will not be able to see them until after final grades are submitted. Proctor Policy Students taking courses that require proctored exams must submit their completed proctor request forms to their instructors by the end of the second week of the session. Proctors located at Columbia College campuses are automatically approved. The use of Proctor U services is also automatically approved. The instructor of each course will consider any other choice of proctor for approval or denial. Additional proctor choices the instructor will consider include: public librarians, high school or college instructors, high school or college counseling services, commanding officers, education service officers, and other proctoring services. Personal friends, family members, athletic coaches and direct supervisors are not acceptable.
