Grading Standards


Dental Hygiene Honor System:

All Dental Hygiene courses adhere to the MSU Code of Conduct. In particular, academic dishonesty, however small, creates a breach in academic integrity.  A student’s participation in this course comes with the expectation that his or her work will be completed in full observance of the MSU Code of Student Conduct.  A student should consult the current Student Handbook for answers to any questions about the code.                                     

Many components of dental hygiene courses are designed to be highly interactive with students helping each other learn.  Students are encouraged to take full advantage of many resources available including course resources, Internet sites, other textbooks and journals, faculty, and peers when answering objectives. This interactive collegial learning environment is conducive for life-long learning.

Cheating includes, but is not limited to, (1) use of any unauthorized assistance in taking quizzes, tests, or examinations; (2) dependence upon the aid of sources beyond those authorized by the instructor in writing papers, preparing reports, solving problems, or completing other assignments; or (3) the acquisition of tests or other academic materials belonging to the university faculty or staff without permission.

Plagiarism includes, but is not limited to, the use of, by paraphrase or direct quotation without correct citation in the text and on the reference list, the published or unpublished works of another person. Students may NOT submit papers and assignments that they have previously submitted for this or other courses. The use of materials generated by agencies engaged in "selling" term papers is also plagiarism. Students are encouraged to review the tutorials and suggested websites for more information about plagiarism. 

Academic dishonesty (cheating, plagiarism, etc.) will not be tolerated in this class. Whenever a student is unsure of whether a particular situation will be interpreted as academic dishonesty, he/she should ask the instructor for clarification.  If students are guilty of academic dishonesty, a grade of zero (0) will be given for the quiz, assignment, etc.  Cases may also be referred to the Dean of Students for possible dismissal from the university.



By enrolling in this course, the student expressly grants MSU a “limited right” in all intellectual property created by the student for the purpose of this course.  The “limited right” shall include but shall not be limited to the right to reproduce the student’s work product in order to verify originality and authenticity, and for educational purposes. Specifically, faculty may submit student papers and assignments to an external agency to verify originality and authenticity, and to detect for plagiarism



The following is excerpted from Clinical Practice of the Dental Hygienist,  12th Ed, by Esther M. Wilkins, Chapter 1: “Each dental hygienist represents the entire profession to the patient being served.  The dental hygienist’s expressed or demonstrated attitudes toward dentistry, dental hygiene, and other health professions, as well as toward health services and preventive measures, will affect the subsequent attitude of the patient toward other dental hygienists and dental hygiene care in general.

..... “A dental hygienist may be involved in a variety of moral, ethical, and legal situations as part of the daily routine.”


Final Course Evaluation:

 The lab exercise (teeth selection and mounting) and combined homework grade (homework papers will be averaged for one collective score ) will be averaged together to count as 10% of the final course grade. The 4 or 5 written exams, inclusive of the final, will be weighted equally and comprise the remaining 90% of the final course grade.   


Students missing an exam due to illness will be allowed to make up the exam on the day of  their return to school.  No grade higher than a 90 will be given for make-up examinations.  Students will be allowed to make up only one (1) exam per semester.  This does not include the Final Exam.       


Missed classes due to extreme illness and/or hospitalization associated with an illness will be evaluated by the course instructor on a case by case basis.



Lab. Exercise (mounting teeth):                              Grade = 100   

Homework Papers (Grades will be averaged):        Final grade =   98

Average =198 ) 2 = 99

Exam 1 = 92                                                                                                                                                                                                                         Lab Practical = 86  

Exam 2 = 90                                   

Exam 3 = 86                            

Exam 4 = 82

 Final  = 94

Test Average = 530 divided by 6 = 88.33


To calculate  10%: 99 x 1 = 99

To calculate  90%: 88.33 x 9 = 794.99


794.99 + 99 = 893.99              893.99 divided by 10 = 89.3      Final Course Grade = 89 / B



GRADING SCALE:   A grade of "C" is required for successful completion of this course.                     

A = 92-100             C = 75-82

B = 83-91               D = 65-74 (Constitutes Failure of Course in Dental Hygiene)                          



 All Midwestern State University (MSU) students may legitimately appeal a course grade if: 1) the student has not been evaluated according to the same criteria as his or her classmates, or 2) an error has been made in grading and/or posting (MSU Student Handbook, p. 37).  In addition, the Office of the Dean of Students has the responsibility to enforce standards of conduct for students as outlined in the MSU Student Handbook (p. 70-80).

 When enrolled in the college of Health Sciences and Human Services (COHSHS), students are often assigned to community agencies, such as health care facilities, social service agencies, or athletic environments, as part of their academic process.  During these experiences, the student is expected to behave in a manner required of professionals working in this environment.  COHSHS students may also be required to successfully complete a licensing/certification process following graduation.  As a result, students in these programs are often held to a different academic and/or behavioral standard than students in other MSU programs.  For example, students may not be allowed to progress in a program if they have been unsuccessful (D or F) in a certain number of courses in the major.  In these circumstances, COHSHS faculty and administration, all of whom have had similar professional experience, may make decisions which negatively impact students’ programmatic progress.


COHSHS students have a right to a review of decisions made by the program faculty, which prevent individuals from progressing in their program in a timely manner.  However, those who participate in the review must understand the context of the professions involved.  Therefore, issues concerning the professional conduct of students in the COHSHS will NOT be brought to the University Grade Committee, but to the COHSHS Student Conduct Appeals Committee.  Specifically, the COHSHS Student Conduct Appeals Committee will review faculty decisions related to:

- Student conduct in a clinical experience, internship, or other work-related environment that   negatively impact the student’s academic progress.      This conduct may include behavior which is  prohibited by licensing and/or professional standards or departmental policy.

- Student removal from a program because of a) professional conduct issues, or b) failure to maintain academic standards required specifically by    the program*




Final Exam

12/13/2016 9 am - 11am

Submission Format Policy

Note: You may not submit a paper for a grade in this class that already has been (or will be) submitted for a grade in another course, unless you obtain the explicit written permission of me and the other instructor involved in advance.

Late Paper Policy

Homework Assignments:

Homework assignments will be given for each chapter of the textbook.  Homework assignments are due on the day that the chapter is begun.  No late papers will be accepted.  It is expected that the student will complete this work in conjunction with reading of the assigned chapters prior to classroom discussion of the topic. 

Plagiarism Policy

Plagiarism is the use of someone else's thoughts, words, ideas, or lines of argument in your own work without appropriate documentation (a parenthetical citation at the end and a listing in "Works Cited")-whether you use that material in a quote, paraphrase, or summary. It is a theft of intellectual property and will not be tolerated, whether intentional or not.

Student Honor Creed

As an MSU Student, I pledge not to lie, cheat, steal, or help anyone else do so."

As students at MSU, we recognize that any great society must be composed of empowered, responsible citizens. We also recognize universities play an important role in helping mold these responsible citizens. We believe students themselves play an important part in developing responsible citizenship by maintaining a community where integrity and honorable character are the norm, not the exception.

Thus, We, the Students of Midwestern State University, resolve to uphold the honor of the University by affirming our commitment to complete academic honesty. We resolve not only to be honest but also to hold our peers accountable for complete honesty in all university matters.

We consider it dishonest to ask for, give, or receive help in examinations or quizzes, to use any unauthorized material in examinations, or to present, as one's own, work or ideas which are not entirely one's own. We recognize that any instructor has the right to expect that all student work is honest, original work. We accept and acknowledge that responsibility for lying, cheating, stealing, plagiarism, and other forms of academic dishonesty fundamentally rests within each individual student.

We expect of ourselves academic integrity, personal professionalism, and ethical character. We appreciate steps taken by University officials to protect the honor of the University against any who would disgrace the MSU student body by violating the spirit of this creed.

Written and adopted by the 2002-2003 MSU Student Senate.

Students with Disabilities

The Americans with Disabilities Act (ADA) is a federal anti-discrimination statute that provides comprehensive civil rights protection for persons with disabilities. Among other things, this legislation requires that all students with disabilities be guaranteed a learning environment that provides for reasonable accommodation of their disabilities. If you believe you have a disability requiring an accommodation, please contact the Disability Support Services in Room 168 of the Clark Student Center, (940) 397-4140.

Safe Zones Statement

The professor considers this classroom to be a place where you will be treated with respect as a human being - regardless of gender, race, ethnicity, national origin, religious affiliation, sexual orientation, political beliefs, age, or ability. Additionally, diversity of thought is appreciated and encouraged, provided you can agree to disagree. It is the professor's expectation that ALL students consider the classroom a safe environment.

Contacting your Instructor

All instructors in the Department have voicemail in their offices and MWSU e-mail addresses. Make sure you add your instructor's phone number and e-mail address to both email and cell phone lists of contacts.

Attendance Requirements

Attendance is critical in order to achieve the maximum benefits of this course.  Reviewing notes and the reading assignments without active participation in the course's clinical activities will not permit the student to adequately meet course objectives.  Therefore, MORE THAN 2 ABSENCES FOR ANY REASON WILL RESULT IN THE FINAL COURSE GRADE BEING LOWERED ONE FULL LETTER GRADE.    In cases of extreme illness and/or hospitalization, individual decisions may be made. 

Students missing an exam due to illness will be allowed to make up the exam on the day of  their return to school.  No grade higher than a 90 will be given for make-up examinations.  Students will be allowed to make up only one (1) exam per semester.  This does not include the Final Exam.       

 Missed classes due to extreme illness and/or hospitalization associated with an illness will be evaluated by the course instructor on a case by case basis.

 TWO (2) tardies will be the equivalent of 1 absence.


Students are responsible for all material presented in lecture as well as assigned reading.  It is the student's responsibility to obtain any handouts or notes missed in class.

Writing Proficiency Requirement

All students seeking a Bachelor's degree from Midwestern State University must satisfy a writing proficiency requirement once they've 1) passed the 6 hours of Communication Core and and 2) earned 60 hours. You may meet this requirement by passing either the Writing Proficiency Exam or English 2113. Please keep in mind that, once you've earned over 90 hours, you lose the opportunity to take the $25 exam and have no option but to enroll in the three-credit hour course. If you have any questions about the exam, visit the Writing Proficiency Office website at, or call 397-4131.
