OPTIONAL SECTIONS: 1.2, 6.4, 8. Required Instructional Activity: This course should be taught with the use of a graphing utility when appropriate. If students use the graphing calculator to graph trigonometric functions, instructors should still require them to write down the amplitude, period, phase shift, vertical shift, and 5 key points. Students should also be required to accurately graph two full periods of the function on paper. Familiarity with the unit circle and the ability to memorize or quickly determine the values of the trigonometric functions for common angles without the aid of a calculator is vital for the students’ success in calculus and is a required component of this course. Required Forms of Assessment: Each instructor must include a set of 9 departmental final exam questions on his or her final exam. These questions will be in direct support of the specific objectives stated in the Core Course Objectives, will be based on material covered in the Required Text Coverage sections, and will be similar to the questions on the Departmental Review Sheet for Trigonometry. These questions should be evenly weighted on the final and should compose at least 15% of the students’ overall grade in the course. The questions will be graded using a departmental grading rubric utilizing a 10-point scale per question. The results of these questions and overall student performance will be reported when final grades are turned in. Please note that the only resource other than a graphing calculator allowed for use by students during the final exam will be a departmental formula sheet. It is also a departmental policy that no TI-89 or TI-92 or comparable calculators be allowed for use during the final exam.
