Professional behavior is expected. Please remember that you signed and agreed to all of the rules, policies, criteria, etc. set forth in the handbook. In addition, please review for the use of cell phones in the classroom and clinic. 2 Course Evaluation As with most courses within the Dental Hygiene Curriculum, this course provides a foundation for other courses, therefore attendance is required. Should an emergency arise, it is the student’s responsibility to contact the course instructor immediately. Further, the student must initiate and be responsible for obtaining any missed information presented during the class(es) missed. Group Assignments, Projects and Presentations: For most assignments student will work collaboratively as groups of 5. These grouping will be determined on the first day of class. In addition, there may be subgroups assigned to portions of various assignments. Course Evaluation Weighting: Unit Objectives and Evaluation (3): 15% Group Assignments/Projects/Presentations (6): 30% Exams (3): 55% Students are expected to come to class prepared, to have completed the assigned reading and/or homework in advance of scheduled lectures, actively participate in activities of learning and apply concepts to contiguous units rather than merely rely on memorization. Deficiencies in any of these areas may be reflected in the student’s final course grade. Late work: Students are expected to complete all course assignments by 8:00am on the posted due date. Grades for all assignments received or completed after the end of the class period in which it is due will be reduced by 50% for each 24 hours period it is late. Since most of the assignments for this class are submitted as a group assignment, all members of the group will receive the reduced grade. It is imperative that all members of each group work together to help each other if someone is unable to complete their portion on time. Course Requirements Unit Objectives (15%) Unit #1 – Normal Periodontium Unit #2 – Classifications of Periodontal Diseases and Conditions, Microbiology of Periodontal Diseases and the Role of Dental Calculus and Other Predisposing Factors Unit #3 – Immunity and Inflammation: Basic Concepts, Microbial Interactions with the Host in Periodontal Disease and Periodontal Pathology Group Assignments, Projects or Presentations (30%) #1 – Presentation – Review of Normal Periodontium (Chapters 4-6) #2 – Presentation – Epidemiology (Chapter 8) #3 – Complete PPT (Chapters 9-10) #4 – Homework and Group Discussion (Chapter 12) #5 – Complete PPT (Chapters 20, 21, 22, 23, 24, 25) #6 – (Small Group) Presentation – Role Playing (Chapters 12, 13) 3 Exams (55%) #1 – History, Chapters 4, 5, 6, (1 hour) #2 – Chapters 7, 8, 9, 10 (2 hours) #3 – Chapters 12, 13, 20, 21, 22, 23, 24, 25 (2 hours) Exams may include essay/short answer, true/false, multiple choice and matching responses. Students are expected to complete any assigned exams on the scheduled dates. There will be no make-up sessions for an unexcused absence and a grade of zero will be given. If an emergency should arise, it is the student’s responsibility to contact the instructor before the scheduled time of the exam to make alternative arrangements. The student must be prepared to make-up the exam prior to the next class session. Alternative arrangements, if any, will be at the discretion of the instructor. Written exams will be graded on the basis of one of the following methods: 1. Straight percentage of points available (students will be advised in advance if this method is used). 2. Adjusted percentage after item audit (allowing for questions to be eliminated). 3. Adjusted to a “class curve”, the highest score earned equaling 100% providing the highest score is not below 92% of the possible points, in which case 92% becomes the base for 100%. If a student earns less than a 2.0 on any of the exams, s/he must make an appointment with the course instructor, within one week of the grades being posted, to review the exam and determine additional course work which needs to be completed in order to show minimum understanding of the material. Course Grading All percent scores earned for the evaluation criteria categories will be added together and converted to a final numeric course grade according to the following scale: 100% 99% 98% 97% 96% 95% 94% 93% 92% 91% 90% 4.0 3.9 3.8 3.8 3.7 3.6 3.5 3.4 3.3 3.2 3.2 89% 88% 87% 86% 85% 84% 83% 82% 81% 80% 3.1 3.0 2.9 2.9 2.8 2.7 2.6 2.5 2.4 2.4 79% 78% 77% 76% 75% 74% 73% 72% 71% 70% 2.3 2.2 2.1 2.0 2.0 1.9 1.8 1.7 1.6 1.5 Decimal grades will be awarded according to the Pierce College Dental Hygiene Department grading scale with the lowest acceptable score being 75% or 2.0 Grade from 1.9-1.6 are considered “probationary” grades and 1.5 or below grades are considered “failing” according to the Dental Hygiene 4 Department Academic Policy and are subject to probationary and/or dismissal actions. By the end of the quarter, each student will have had the opportunity to attain minimum competency in the expected student outcomes. If it is determined by the course instructor that a student has not successfully achieved the student outcomes, the student may have additional course work assigned, the course grade adjusted accordingly (reduction of grade or incomplete grade with remediation assigned to determine competency in all course objectives), and/or the student may be placed on academic probation with possible dismissal from the Dental Hygiene Program as outlined in Pierce College Department of Dental Hygiene Program Policy. Incomplete Grades The student must complete all course requirements and attain a minimum grade of 2.0 in the course to progress to the next sequential courses. Incomplete grades are expected to be completed within the first 3 weeks of the next quarter. The student is responsible to schedule an appointment with the course instructor to examine the reason the coursework has not been completed and define a plan for completion of the course. Students are expected to submit, in writing, their proposal for completion of requirements to the course instructor at this meeting. If the work is not completed at this time and there are no extenuating circumstances for the work to be outstanding, the final course grade may be changed to a 1.5. Additional Grading Factors Professionalism – Students are expected to project professional conduct and communication towards faculty, staff, classmates, patients and visitors at all times as outlined in the Department of Dental Hygiene Program Policy. Deficiencies in professional conduct and communication will be reflected as a reduction in the student’s final course grade. Honesty – Students are expected to demonstrate unquestionable honesty at all times as outlined in the Department of Dental Hygiene Program Policy. Deficiencies in honesty will be reflected as a reduction in the student’s final course grade. Breeches in the Academic Honesty Policy may be subject to the student’s immediate dismissal from the Dental Hygiene Program. Considerations which may be reflected in the student’s final course grade include: *promptness to class sessions *preparation and participation during class sessions *individual effort put toward group assignments/projects/presentations 5 Schedule Topic Week 1 January 7 Week 2 January 14 Week 3 January 21 Reading/Assignments Review Syllabus Review assignments, projects, requirements Create groups Introduction to Periodontal Disease Syllabus Historical background Review normal periodontium Introduction: History pp 1-9 (9) Chapter 4: The Gingiva (18) Chapter 5: The Tooth- Supporting Structures (20) Chapter 6: Aging and the Periodontium (5) Exam #1 (1 hour) History, Chapters 4-6 10am-11am in SNR 213 Assignments (Due dates noted) Bring textbook to class.

Course handouts are for the purpose of directing self-study and note taking. PowerPoint presentations are provided on Angel for study and review. It is not considered a requirement to print all presentations for class. They will be heavily loaded with color graphics and photographs that can be time and ink intensive to print. Students are encouraged to use a variety of note taking strategies and should consider printing only what they individually wish to have in class. Using “draft” and “grayscale” print modes can conserve on ink. Faculty are not required to post multiple versions for convenience as these are supplemental to class and an “added benefit”. 7 The syllabus may be altered at any time during the course as deemed necessary by the instructor. Changes requiring a schedule or time frame alteration will be given with sufficient notice for students to accommodate. Emergencies are the exception. Security/Emergency Procedures for Classrooms Call 911 and then Campus Safety in response to an imminent threat to persons or property. In the event of an evacuation (intermittent horns & strokes), gather all personal belongings and leave the building using the nearest available safe exit. Be prepared to be outside for one hour and stay a minimum of 200 feet from any building or structure. So long as it is safe to do so, students are expected to stay on campus and return to class after evacuations that last less than 15 minutes. Do not attempt to re-enter the building until instructed by an Evacuation Director (identified by orange vests) or by three horn blasts or bell rings. Please notify the nearest Campus Safety Officer or Evacuation Director of any one left in the building or in need of assistance.
