(
maximum

of two

attempts
).

If a grade higher than the minimum passing score
is obtained on a make
-
up test, the minimum passing score will be recor
ded. F
ailure to meet
minimum score

on the test

will result in f
ailure of the course therefore,

dismissal fro
m the
program.


Laboratory Evaluations

will compromise 30% of the course grade. Using the concept of
"mastery learning" each student must complete the following full mouth surveys on
manikins at the stated proficiency levels

of 85% with no more than 3 FMS

periapical
retakes and
2 Bitewing retakes
:

In addition to completing two DXTTR’s
, students must also demonstrate
competence in the
following:


Mounting, 2 Full Mouth Surveys at 100% proficiency

1 Patient survey at 85
% proficiency

(maximum

of
three

retakes on a 18
film
FMS
)


Manikin surveys are weighted as follows:

Adult DXTTR’s

Subsequent
to meeting manikin requirements, each student will be required (prior to
graduation) to expose, process, moun
t and critique
three

full mouth surveys on patients
using the paralleling technique. Again, a

minimum proficiency level of 85
% will be
required wi
th no more than
three

retakes
.


In addition, written "pop" quizzes will be given periodically during lab sessions. These
quiz grades will be averaged in with the lecture quizzes
.


Minimum passing average for the laboratory portion of this course is
85
%
.


Students will continue toward developing clinical competency by meeting additional radio
logy
requirements in the DEN 112BB, DEN 106, and 107
.

Academic Integrity


Students enrolled
at Alamance Community College are expected at all times to uphold
standards of integrity. Students are expected to perform

honestly and to work in every way
possible to eliminate academic dishonesty. Academic dishonesty includes cheating and
plagiarism.


Plagiarism is stealing another person’s words or ideas and passing them off as your own.
When you put your name on a paper
in a course at ACC, you are claiming ownership
of that paper
. You are saying, "I wrote this paper and the words and ideas in it are my own,
except where I have credited my source through proper MLA or APA documentation."



Global Plagiarism

Global plagiari
sm involves copying an entire paper from another source, perhaps by
borrowing a paper someone else wrote or downloading one from an Internet site. This type of
plagiarism is grossly unethical and inexcusable. If you are caught committing this type of
plagi
arism, even on a rough draft, you will receive
a zero on that assignment. This
typically results in an "F" in the course
. Sometimes students commit this type of
plagiarism because they have waited until the last minute to do an assignment and they
panic. H
owever, a student would be much better off dropping the course than earning an "F"
because of plagiarism.


Patchwork Plagiarism

Cut and paste plagiarism, also called
patchwork plagiarism
, is no more ethical than global
plagiarism. This type occurs when the

writer cuts and pastes words, paragraphs, and even
pages from different sources to create a whole paper which he or she then turns in as his or
her own work. The student may have written an introduction, conclusion, or even a few
transitions, but copied t
he rest of the paper word for word from different sources. Committing

cut and paste plagiarism will also result in
a zero on that assignment and can result in an
"F" in the course.



Incremental Plagiarism

Incremental plagiarism

s
ometimes

happen

through carelessness or by accident. It occurs
when the writer composes most of the words, but does not properly cite or credit the sources
or does not paraphrase or quote correctly. Simply rearranging the words in the passages is
not enough. A paraphrase

should truly be in the writer's own words. Students are responsible
for understanding how to use MLA
or APA
Documentation, which is covered in course
textbooks, handbooks, the laminated guide (included with the Hacker handbook), and online.
Rough drafts w
ith incremental plagiarism may be rewritten to eliminate the problem. Final
drafts with incremental plagiarism will receive a grade penalty consistent with the amount and
seriousness of the plagiarism.


Final Thoughts on Plagiarism

As a student,
y
ou are re
sponsible for the integrity of your work
. If you are not confident
about your writing ability, your instructor and the tutors in the Academic Skills Lab
are there
to help you. We as a
department are committed to the idea that writing is a process and that
we all make mistakes and can learn from these mistakes. We allow submission of rough and
final drafts to help you grow and learn as a writer. How can we help you if the words and
ideas you turn in are not your own? Please do not put us in the position of h
aving you fail one
of our courses because of plagiarism. The experience will not be pleasant for any of us.


How Do we Detect Plagiarism

The Health and Public Services Division may use a plagiarism detection service called
Turnitin.com
to check papers for
plagiarism. You will probably be asked to submit your
papers to Turnitin.com online or to submit your papers in electronic format to be checked for
plagiarism.

Also the Google web site is used to verify authenticity of your papers. Either source will be
used to document plagiarism, upon which appropriate sanctions will be utilized.

Cheating


Any such action observed by a faculty member will result in an automatic “F” on the test for
those involved. Any student caught cheating will be dismissed at the
discretion of the
instructors.






OTHER POLICIES


Students must comply with the Uniform and Supply policies listed in the Dental Assisting
Student Handbook during both laboratory and clinical settings.


Attendance



ACC recognizes that students are adults

with many responsibilities. An occasional absence
might be absolutely necessary. However, such absences in no way lessen the student’s
responsibility for meeting the requirements of the class.


Absences are counted from the first official meeting of the c
lass regardless of when the
student registers for, or enters, the class. Refer to the policy on page 86 of the student
handbook. Individual departments/programs may set more restrictive attendance
requirements with the approval of the associate dean.


St
udents who exceed 3 lecture and 3 lab hours of absences in DEN 112 will be dropped from
the roll. Absence due to prolonged illness must be confirmed by a doctor's statement.


Any quiz or exam missed due to an
unexcused absence

will result in a grade of "0
". In the
case of an
excused absence
,
the student must take the make
-
up test

or exam immediately
upon return to classes. Failure to follow this procedure for an excused absence will also
result in a grade of "0" for that particular test or exam.


Students are expected to attend each class session. When classes must be missed due to
personal emergencies, sickness or death of an immediate family member, students may use
up to the maximum number of absences listed on the official Attendance Policy St
atement
distributed during orientation. Three tardies are counted as one absence. Absence from
class does not relieve the student from the responsibility of meeting all course requirements.
Students exceeding the maximum number of allowed hours will be
dropped from the course,
at the instructor’s discretion.


If the attendance policy is violated after the withdrawal date (WP), the student will receive an
F in the course and will be dismissed from the program and will no longer able to attend
class
.


Stud
ents who withdraw or are dismissed for academic reasons or for violation of college
policies must reapply for readmission into the Dental Assisting Program. Re
-
entry will be re
-
evaluated after a 1 semester wait from the initial drop date, and will be depe
ndent upon
available space and faculty review. Readmission will require that the student repeat the
entire

Dental Assisting Curriculum, regardless of prior enrollment progression
.


Refer to your
Student Handbook

for additional information on attendance policies.



ACC’s Quality Enhancement Plan (QEP)


As part of the reaffirmation process with the Southern Association of Colleges and Schools
Commission on Colleges in 2013, ACC has developed a Quality Enhancement P
lan (QEP)
that identifies a specific area for improvement. Entitled “Write to Succeed,” ACC’s QEP
focuses on improving student writing so that graduates are better prepared both for the
workforce and for further education. As a result of “Write to Succee
d,” ACC has opened a
Writing Center (located in Main 354 in the same suite as the Academic Skills Lab). The
Writing Center offers assistance with any writing task, as well as style guides and workshops,
to help students be more successful in all of their c
lasses. For more information, please visit
the college’s website.










Library


Learning Resource Center LRC


As part of ACC’s commitment to institutional effectiveness and student success, it is critical
for students to learn how to use the resources
in the library. Many classes require research
projects and papers that use those resources. Students need to know how to use the
resources effectively. For information regarding help and use of the LRC call 336
-
506
-
4208.



ADA Policy


Alamance Community C
ollege is committed to providing equal educational opportunities for
students with documented disabilities. Students who require disability services or reasonable
accommodations must identity themselves as having a disability and provide current
diagnosti
c documentation to the Disability Services Office located in the Gee Building, Room
128. All information is confidential. Please contact Monica Isbell, Coordinator of Special
Needs & Counseling Services for more information at 336

isbellm@alamancecc.edu


Children on Campus


Alamance Community College does not allow children of students, faculty or staff to enter
classrooms, labs or shops while instruction is being delivered. Similarly, ch
ildren of students,
faculty or staff are not to be left unattended in any college facility at any time.




Course Withdrawal


Withdrawal date

and receive a WP is ___
November 20, 2013
_____


Alamance Community College recognizes that from time to time, it
may be necessary for a
student to withdraw from a course. Students may withdraw with a “WP” grade through the 80
percent point of the semester. If a student withdraws during the last 20 percent of the
semester, the earned grade in the class will be record
ed on the student’s transcript.
Students who formally withdraw many NOT continue attending that class.


When a student misses 20 % or more of the total contact hours for this course, the student
will be withdrawn by the instructor from the course.


If
a student does not properly withdraw or the faculty fails to withdraw a student an F will be
assigned as a grade for the class.


Students who never attend or withdraw prior to the 10% point and are receiving federal
financial aid are required to repay the

full amount charged for tuition, books and fees.
Students who withdraw through the 60% point of the term and who are receiving
federal financial aid (Title IV programs) are required to repay a portion of the awarded
funds for which they are not eligible
due to withdrawal.


Electronic Communication Devices Policy



Alamance Community College is committed to fostering a learning friendly environment.
Electronic communication devices can be detrimental to the learning environment. Therefore,
the use of cell
phones and beepers in the classroom must be turned off or put on
silent/vibrate mode.


All devices must be placed in a bag out of sight and reach during
testing.



Student Code of Conduct


Students at ACC are expected to conduct themselves as adults in acc
ordance with generally
accepted standards of behavior and decency at all times. Student rights, responsibilities, and
procedures are outlined in the current ACC Student Handbook(Student
Rights/Responsibilities). Each department/program may choose to have
a specific
departmental handbook with specific requirements for clinicals, co
-
ops or other pertinent
information.


If a student's behavior is interfering with classroom procedure, he/she will be asked to leave
the class and will be counted absent for that
session; the student will then be referred to the
Associate Dean of Public Services. If the disruptive behavior continues, the student will be
dropped from the class. Disruptive behavior may include, but is not limited to: cell phone
talking and text me
ssaging, sleeping in class, threatening the instructor or other students,
fighting, using profanity, talking with or otherwise disturbing students, talking so loudly as to
interfere with the instructor and/or the class, etc.


Students appearing to be under

the influence of drugs/alcohol while on the school premises
will be asked to leave class. If the student refuses to leave the instructor will need to contact
the Associate Dean at which time sanctions will be leaved for such behavior (Student
Handbook Pa
ge 94, Sanctions).



Safety


Emergency Evacuation


An emergency evacuation route is posted in the classroom. Please review the posted route
for the closest emergency exit. Assume that when the building alarm is sounded, an
emergency exists. Walk quickly t
o the nearest marked EXIT to evacuate the building.

Campus emergency phone number is 2286.
