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 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
0 - 0% |
| None | |
| Skill Demonstrations: All skill-based and physical demonstrations used for assessment purposes including skill performance exams. | Skill Demonstrations
80 - 90% |
| Equipment set up and shut down; cutting projects | |
| Exams: All forms of formal testing, other than skill performance exams. | Exams
0 - 0% |
| None | |
| Other: Includes any assessment tools that do not logically fit into the above categories. | Other Category
