Program/Discip
line
Requirements:
If applicable
ASSIGNMENT: Must be completed on time (beginning of class period)
and according to specified criteria. You are responsible for all
reading assignments in course texts and handouts in addition to the
content of the lecture and laboratory sessions themselves. Since
information in each assignment will be used during the class sessions
for discussions, it is essential that materials be carefully studied prior to
class or laboratory
STUDENT SUCCESS: To successfully complete this course, the student
will need to Complete assignments as indicated on the schedule.
Read weekly topic objectives before class and studying for a test. Ask
the instructor for help as soon as you realize you are having difficulty.
Take notes during class and place a question by anything you do not
understand. Additional recommendations can be found in the Dental
Health Program student manual *Lab grade will be included into your
Lecture grade. Students are required to pass both Lecture and Lab to
advance to DH spring semester. ** A final grade below a (75%) will
interrupt a student’s progress through the Program and may result in
dismissal from the Program. If you are having trouble with this course, it
is your responsibility to contact the professor immediately and
arrange for tutoring or other assistance.
COURSE REQUIREMENTS:
Lab/Clinic: Students are only allowed in lab or clinic with direct faculty
supervision. Students participating in clinical activities are to be in
clinic attire.
Professional Policy: Students are expected to participate fully in all lab
and clinical activities and to model professional behavior at all times.
All students are considered mature enough to seek faculty assistance
and to monitor their own progress in meeting course requirements.
Please see the DH handbook for more details on Academic Integrity.
Daily Progress: The instructor will record your progress and discuss
suggestions with you. This will help the student understand the
progress of the appointment and determine the final treatment.
ATTENDANCE POLICY:
Arrangements must be made that do not conflict with class times for
doctor’s appointments, sick family members, and transportation
needs. In cases of emergency or illness, the student must contact the
instructor prior to class (or lab) should an absence be anticipated.
Class handouts can be obtained from the instructor. Class notes can
be obtained from classmates. One point will be deducted from the
final average for each unexcused absence and ¼ point for each
tardy; 4 tardies will equal 1 absence. Students are considered tardy
five (5) minutes after class start time. Calling prior to class does not
result in an “excused” absence or tardy, but rather assists the faculty
in evaluating the student’s progress in professionalism. The student will
receive an attendance report for each absence or tardy. If you are
not present, you are not learning the information or putting in the
necessary time to develop your skills. See Dental Hygiene Handbook
for additional stipulations.
MAKE-UP POLICY: The student will not be able to make up exams or
quizzes without a doctor’s note and/or at the instructor’s discretion.
The student will receive a “0” for that exam or quiz. If a make-up is
given, the make-up exam will be different from the one given at the
scheduled time. The student must make an appointment with the
instructor for the make-up exam. Any student arriving after a test or
quiz has been handed out will only be allowed the original time set by
the instructor for completion. Any student arriving after a quiz or
exam has been turned in by another student will not be allowed to
take the test and will receive a ‘0’.
