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 20 - 35%
Manual drafting projects
Skill Demonstrations: All skill-based and physical demonstrations used for assessment purposes including skill performance exams.		Skill Demonstrations 40 - 60%
Linework, freehand, geometric and orthographic exercises, constructions and projections
Exams: All forms of formal testing, other than skill performance exams.		Exams 10 - 30%
Objective examinations (multiple choice, true/false, matching items, completion), quizzes, final exam
Other: Includes any assessment tools that do not logically fit into the above categories.		Other Category 5 - 10%
Participation
