Expected Student Behavior

Student Conduct and Responsibilities

A high standard of conduct is expected of all Amarillo College students.  The Student Code of Conduct is defined in the Amarillo College Student Rights and Responsibilities publication. This document may be located online at http://catalog.actx.edu/content.php?catoid=7&navoid=291#StudentConduct .

 

“Amarillo College expects a high standard of conduct from its students. Students are expected to comply with the law, respect proper constitutional authority, and obey College policies, rules and regulations. Unacceptable conduct is defined as an action or behavior that is contrary to the best interest of a fellow student or students, the faculty or staff, the College, or the teaching/learning process. Students failing to perform according to established standards may be subject to disciplinary action.  Policies, standards, rules and regulations apply to students attending College activities whether the activity takes place on or off campus. 

Each student shall be responsible for becoming knowledgeable of the contents and provisions of College policies, rules, and regulations concerning student conduct. In some cases, individual programs may have approved policies for student conduct which also apply to student conduct in those programs.”

 

The Amarillo College Dental Hygiene Program has specific policies which apply to student conduct within the program.  These policies may be implied or written.  The course syllabus and the student manual are sources for specific student conduct policies for dental hygiene students at Amarillo College.

 

Professional Standards

All dental hygiene students are expected to demonstrate professionalism in behavior, manner, and judgment in the dental hygiene clinic and voluntary enrichment rotations.  The area of professionalism includes appearance, asepsis, patient management, peer, faculty and staff interaction and documentation.  Guidelines for professionalism and professional appearances are discussed in the AC Dental Hygiene Clinic Manual.  Professionalism will be evaluated on a continual basis.

Students will exhibit professional maturity and an acceptable level of clinical judgment as determined by the faculty.  Unprofessional behavior may be defined as a continual pattern of misconduct and/or an egregious act that endangers the health of the patients, students, faculty, and/or College.  Egregious acts also include violations of the Texas Dental Hygiene Practice Act or falsification of patient records and/or faculty signatures.

Students must be competent in the application of the principles of ethical reasoning, ethical decision making and professional responsibility as they pertain to patient care.  Dental hygienists should understand and practice ethical behavior consistent with the professional code of ethics throughout the educational experiences.  The following are examples which are considered professional standards.  These are representative examples and may not be all inclusive. 

• Students are concerned with excellence in learning rather than just meeting minimal criteria.
• Students maintain composure, dealing with conflict in a constructive way.
• Students exhibit an attitude of respect for classmates, faculty, and staff.  If a student has a conflict with a grade given by the instructor, the student must follow the outlined grievance procedure.  Faculty will not change a grade given to a student from another faculty member.

 

Safety:  Individual Responsibility

This course supports the Amarillo College policies regarding responsibility for a safe environment.

Amarillo College is in compliance with environmental, health and safety regulations, and therefore requires that all AC employees, students, and visitors comply to maintain a safe environment.

Report hazardous conditions and safety concerns immediately to their supervisors, instructors, staff, and/or emergency management personnel, as appropriate.

Abide in safe practices and procedures established by the College.

Adhere to and cooperate fully with all local, state, and federal regulations concerning environmental, health, and safety issues.

Take action to resolve workplace issues when appropriate.

Statement of Confidentiality

Confidentiality is the duty owed by dental hygiene professionals, including students enrolled in Dental Hygiene accredited programs, to protect the privacy of all patient information.  Dental Hygiene professionals clearly have an obligation to keep MEDICAL and PERSONAL information about patients in the strictest confidence at all times.  Unless disclosure is mandated by patient consent, statute, a duty to inform third parties, or special circumstances, dental hygiene professionals have a clear duty to maintain confidentiality of all patient information.

Breach of duty to hold such information in the strictest confidence, may cause liability for the individual student such as fines, imprisonment, and dismissal from the program.  In the professional “Code of Ethics”, the American Dental Hygienists’ Association Code of Ethics for dental hygienists has published the following statement which all dental hygiene professionals (including students) must always follow:

“We respect the confidentiality of client information and relationships as a demonstration of the value we place on individual autonomy.  We acknowledge our obligation to justify any violation of confidence.”

Instructor Help and Student Participation

It is very important that you seek faculty input regarding your performance so that you may:

• Gain confidence in your performance
• Identify problem areas and determine methods for correcting deficiencies
• Attain competence

All students are considered mature enough to seek faculty assistance and to monitor their own progress.  Please meet with your assigned instructor as soon as possible if you have questions or difficulties in this course.  Faculty are committed to supporting your success.  Please remember, however, that you are the only person who can make us aware that you need assistance.

Amarillo College Dental Hygiene Mentoring Program

The student has a very important role in the mentoring process.  Each student will be assigned a mentor at the beginning of the semester.  The mentor/mentee list will be posted in the locker room and emailed to each student.  As partners in the mentoring relationship, students have responsibilities to:

• Contact mentors and arrange for a mentoring appointment:  1 in February and 1 in April
• Be aware of their mentoring needs and discuss these needs with mentors
• Maintain regular communication with their assigned mentors

Prepare for mentoring meetings by:

• Setting daily and weekly goals for program progression
• Assessing attainment of these goals
• Identifying impediments to achieving these goals

It is the student’s responsibility to contact mentors and arrange appointments.  Failure to arrange and/or keep appointments will result in a two-point deduction from the final course grade for each occurrence in the semester.

Mandatory Tutoring

In an effort to increase student success in DHYG courses, and to assist students having difficulty understanding complex subject areas, any student who scores below a 75% on any assessment (excluding the final) must meet with faculty and  complete a mandatory tutoring before taking the next assessment.

 

Cell Phone and Electronic Device Policy

Cell phones and other electronic devices may detract from the learning environment.  For this reason, they should be silenced and put away out of view before entering the classroom.  The personal use of cell phones in the classroom is not permitted.  Cell phones may be checked at designated break times.  Students who choose to violate the cell phone policy in class will receive a 0.

Mailboxes

Each student is assigned a mailbox located inside the student locker room.  Students are required to check his/her mailbox daily for various communication from faculty.

Grading Criteria

Assignments and Examinations

The following criteria will be used to determine the student’s grade:

The course will consist of major examinations, Pretest/quizzes, online assignments, laboratory practical examinations and a comprehensive final examination.  Changes in the major examination schedule will be announced approximately one week in advance.  Quizzes may, or may not, be announced in advance.  Refer to the course calendar for the schedule of materials to be covered in each class or lab session and the tentative examination dates.  Also, please note the provisions of the Make-up Policy in this syllabus for missed examinations.  Major examinations and quizzes will be objective in nature (true/false and multiple choice) with a few questions being subjective in nature (short answer, essay, and fill in the blank).  The final examination will be entirely objective in nature and will test information for the entire course.

 

Students with questions regarding examination results may review examinations, under the supervision of the course faculty.  Students, who feel that a question was scored improperly, must submit the following to the course director, in writing:

1. Student name
2. Exam number
3. The examination question and the reason for requesting an instructor review of the score.
4. The page and paragraph number, in the student’s course textbook or lecture notes, that verify that the student’s answer is correct.

The request must be submitted to the course director within one week after the graded examination is returned to the student.

 

Students will not have access to review and study prior quizzes or major examinations in preparation for the final examination.  Students should not rely on memorization of specific test questions; instead, the student should have a general knowledge of the course objectives to be successful in learning the material in preparation for the comprehensive Final Exam in this course and for the Dental Hygiene National Board Examination.

 

Laboratory Assignments

The laboratory x-ray machines are used in the digital mode and the student will be required to capture images using sensor receptors and will learn to record the images in the proper format in the patient’s chart during each lab period.  Attire for radiology lab must follow the guidelines of lab or clinical attire discussed in the Amarillo College Dental Hygiene Student Handbook. The following assignments must be completed in order to complete the course.  The criteria for quality assessment and the grading of lab radiographs will be based on the Criteria for Clinical Radiographs which includes the policies that will also be utilized in Clinic II, Clinic III, and Clinic IV.  The Criteria for Clinical Radiographs policy is included the Amarillo College Dental Hygiene Student Handbook.  The student is expected to utilize the Criteria for Clinical Radiographs as a guide to the assessment of the films taken in laboratory and clinical sessions.

Please note that the retake policy in the Criteria for Clinical Radiographs applies to clinic patient radiographs and will not be applied to Dexter Manikin Radiographic sets.  Students are allowed to utilize the Dexter Practice sessions to learn to expose, process, and assess errors, and may take unlimited retakes until the student is confident in their technique. 

Written Lab Examinations may be given through the semester to test the student’s knowledge in critiquing radiographs for errors, anatomical landmarks, and interpretation of the health status and pathological findings of the tissues as seen in radiographs.  

The following Lab Assignments will be completed by the student in radiology lab sessions utilizing digital sensors and manikins:

Bitewing and Full Mouth Radiographic Surveys:

7 Bitewing surveys

• 5 horizontal surveys
• 1 vertical survey on adult manikins
• 1 Bitewing Exit Examination

7 Full mouth radiographic surveys using the Paralleling Technique 

• 4 adult -18 image surveys
• 2 surveys on a pedodontic typodonts
  • 1 Early Eruptive Stage Survey
  • 1 Mixed Dentition Stage Survey
• 1 Full Mouth Exit Examination

Accessory Techniques:

Each accessory techniques will be taught to laboratory competency and will be graded as instructed on the competency form for each technique.

• •  
• Bisecting Angle Technique (Periapical radiographs will be practiced using the bisecting angle receptor stabilization device.)

• Occlusal Competency exercise will be completed as outlined on (maxillary and mandibular arches) on an adult Dexter manikin and on a Pedodontic manikin.

• Localization Competency exercise

• Phosphor plates will be utilized to expose a prescribed exercise which will then be developed and mounted in the patient chart utilizing the Scan-X processor.

• The Nomad portable x-ray machine will be utilized to expose a prescribed exercise.        

Phosphor Plates, Scan X and the Nomad

The proper care and use of Phosphor Plates, the Scan-X, and the Nomad portable X-ray machine will be taught and each student must pass a written test on the Care and Use of the Phosphor Plates and the Scan X machine and another exam will be administered on the care and use of the Nomad machine.  The examinations must be passed with a grade of 100.  The student may review the material and retest until the grade on the examinations are score of 100.  After the written exam is passed on the phosphor plates/Scan X and the Nomad, the student also be required to complete a prescribed laboratory exercise on a manikin using each type of equipment to competency level of achievement.

 

Laboratory Professionalism

The student will be expected to maintain a professional attitude and personal responsibility as they work to complete the assignments and learning experiences in the Dental Radiology Laboratory.  Each day in the laboratory, a Professionalism Grade Form must be assessed and signed by a laboratory instructor in order for the student to receive a grade for that laboratory session.  The student must keep this grade form in their Radiology Lab Folder and have the laboratory instructor complete the form at the end of the session or the grade will be a “zero”.  Any deduction on the form due to student error will be assessed as a “zero”.  No deduction in grade will be assessed as a “100” for the day.  At the end of the semester, the professionalism grades will be averaged to form one grade which will count for ten percent of the student;s semester grade. The grade will be based on:

• Attendance: 
  • The following are examples to be assessed but are not limited to:  
    • Student is present and has the needed supplies for the laboratory session

10%   Laboratory Professionalism

The following grade scale applies throughout this course:

A = 93 - 100%            

B = 83 - 92%

C = 75 - 82%

F = below 75%

Note:  A grade of "D" is not possible in this course.

In order to pass the course, a student must achieve a final grade of 75% and meet all requirements of the course.  All students are considered mature enough to seek faculty assistance and to monitor their own progress in meeting course requirements.  Students who continually fall below the minimal level of 75% on graded material should seek assistance from the course faculty. 

 

Make-up Policy

A student will not be allowed to make-up quizzes, as a zero will be given for each missed quiz.  If a student is absent on the day when a major examination is given, the student may make-up the missed work as follows:

1. It is the responsibility of the student to make arrangements with the instructor within 24 hours of returning from the absence to reschedule the examination.
2. The missed work must be made up within TWO Amarillo College school days where the day ends at 4:00 p.m.
3. The makeup work may earn a maximum of 80% of the original point value.    

Attendance

Attendance Policy

“Regular attendance is necessary for satisfactory achievement. Therefore, it is the responsibility of the student to attend class in accordance with the requirements of the course as established by the instructor.”  (Amarillo College Student’s Rights and Responsibilities Publication)

 

Due to the tremendous amount of information contained in this course, the student who plans to succeed should also plan to attend all course sessions regularly and promptly.  Without question, the instructor expects each student to be present at each session.  Unfortunately, no one has ever developed a short cut which will replace hours of actual experience needed to master a new skill; therefore, students must be present to acquire the specific knowledge in this subject. 

 

Absences will be monitored and evaluated to determine the student’s final course grade.  The student may have no more than 1 absence in this course without affecting the final grade.  Beginning with the 2^nd absence, 2 points will be deducted from the final grade; on the 3^rd absence, 3 points will be deducted; on the 4^th absence, 4 points will be deducted.  On the occurrence of the 5^th absence, the student will fail the course and be required to repeat the course.  Attendance will be taken at the beginning of each lecture and lab session.  Students not present when attendance is taken will be counted as absent. The student is expected to be present in class at the time class/lab is scheduled to begin. STUDENTS, WHO ARE LATE TO CLASS OR LAB OR WHO LEAVE CLASS OR LAB EARLY, WILL BE COUNTED AS ABSENT.  The student will receive 2 bonus points to the final grade of this course if the student has perfect attendance for the semester.
