Classroom Policy
1
Disruption in class will result in being dismissed from the classroom and/or any disciplinary action
2
Any additions as discussed/suggested by the class.
Plagiarism is a serious issue and can result in penalties in both course and lab work.
On Plagiarism
In speaking or writing, plagiarism is the intentional or unintentional act of representing someone else's work
as one's own. In addition, plagiarism is defined as using the essential style and manner of expression of a
source as if it were one's own. If there is any doubt, the student should consult his or her instructor, or
document the source in a footnote or other form of citation. Any statement made without documentation will
be interpreted as the student’s own words and may therefore be interpreted as plagiarism.
Your work in this course may be submitted to turnitin.com , an online plagiarism-checking service.
Turnitin.com operates a secure database and protects your privacy by assigning code numbers, not student
names, to all student work stored in its database. The purpose of using this service is to help protect the
integrity of a DeVry credential, which in turn helps protects your investment in a DeVry education. We will
assume we have your consent to submit gradable work in this course to turnitin.com unless you indicate
otherwise.
