Methods of Evaluation/Basis of Grade.

Writing: Assessment tools that demonstrate writing skill and/or require students to select, organize and explain ideas in writing.		Writing 0 - 0%
None
This is a degree applicable course but assessment tools based on writing are not included because problem solving assessments and skill demonstrations are more appropriate for this course.
Problem solving: Assessment tools, other than exams, that demonstrate competence in computational or non-computational problem solving skills.		Problem Solving 40 - 55%
Audio project(s)
Skill Demonstrations: All skill-based and physical demonstrations used for assessment purposes including skill performance exams.		Skill Demonstrations 25 - 35%
Hands-on proficiency demonstrations
Exams: All forms of formal testing, other than skill performance exams.		Exams 10 - 25%
Terminology quizzes
Other: Includes any assessment tools that do not logically fit into the above categories.		Other Category 5 - 10%
Attendance and participation, lab hours
