Additional NotesProfessionalism Gross violations of the formal codes are governed by

University laws, which delineate the procedures to determine whether a violation of the code of ethics occurred and, if so, what remedies should be imposed.

We encourage students to abide with the more sensitive approach to this by allowing the practice of a high Morality (or proper behavior), which defines right and wrong by the society, philosophy, religion, and individual conscience.

Students and their instructors often make ethical choices reflexively/ But ethically sensitive situations, where time, emotions and marks are pressured, it becomes all too easy to be blind-sided by temptation/ The best antidote to ethical lapses is to commit in advance to a set of ethical principles - your personal ethical code that follows or grows to it.

Any difficulty or concern during the course should be passed directly to the course coordinator.

Makeup Exams It is applicable when an acceptable and valid excuse is presented at the applicable time

Drop Dat N/ACheating It is unethical and illegal by any means

JUST regulations will be applicableAttendance It is mandatory for all lecturesAbsenteeism To receive course credit, a student should attend a

minimum of 90% of the contact hours of the class. Students who are absent for the lecture must contact the

course coordinator prior to the class. If absent from lectures, then the course coordinator will

refer to related guidelines set by the university. Any student who is absent on a test day, will have to

demonstrate an acceptable medical or social statement explaining the illness or personal crisis as instructed by their faculty.

Individual instructors may accommodate by

Page 9: Dent 203

arrangements for a make-up test only when a written request is sent to and approved by the Dean.

Students with Special needs

Any student who feels that s/he may need accommodation for any type of disability is encouraged to contact the course coordinator who will be happy to help in any way.

Accommodations to the course plan can be tailored to the needs of specific individuals after consultations with the dean.

Participation All students are highly encouraged to participate in the classes.

Individual conferencing and consultations

The course coordinator is always available to talk with the student when problems arise.

If you have any problems that require the attention of an instructor, do not wait until the problem is insurmountable.

If a student must talk with the course coordinator after office hours, an appointment can be made for that time.

Do not allow tension to build-up to unsolvable proportions.

Course changes

Information contained in this course outline is correct at the time of publication.

Content of the courses is revised on an ongoing basis to ensure relevance to changing educational, employment needs.

The course coordinator reserves the right to add or delete material from courses and will endeavor to provide notice of changes to students as soon as possible.

The timetable may also be revised accommodating to holidays and unexpected off days.
