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 5 - 10% |
Chapter review questions | |
Skill Demonstrations: All skill-based and physical demonstrations used for assessment purposes including skill performance exams. | Skill Demonstrations 20 - 30% |
Demonstration worksheet; skill demonstrations | |
Exams: All forms of formal testing, other than skill performance exams. | Exams 50 - 70% |
Quizzes and final exams | |
Other: Includes any assessment tools that do not logically fit into the above categories. | Other Category 5 - 15% |
