Addendum to Course Description
Update and revise CCOG's so that course materials do not overlap with other courses taught in the OMT program
Intended Outcomes for the course
Upon successful completion students should be able to:
- Effectively perform automated visual field testing in the clinical setting.
- Skillfully assess and evaluate the visually compromised patient in the clinical setting.
- Apply the vision screening process to patient intake under the supervision of a qualified ophthalmic technician.
Course Activities and Design
The class will be presented by means of lecture/discussion, audio-visual presentations, handouts and demonstrations. There will be comprehensive lab work requiring demonstrated competency to receive a satisfactory grade. Guest speakers and field trips may be utilized by the instructor as a means of assisting the student in mastering course goals and objectives.
Outcome Assessment Strategies
At the beginning of the course, the instructor will detail the methods used to evaluate student progress and the criteria for assigning a course grade. The methods may include one or more of the following tools: examinations, quizzes, homework assignments, research papers, laboratory modules and student participation.
