Assessment and Requirements
Methods for measuring achievement of objectives:
- Tests will be given throughout the semester. Tests scores represent 65% of the course grade.
- Laboratory activities and performance exercises will be done where students will demonstrate an understanding of practical applications. These will make up 10% of the course grade.
- A written final exam will be given which will represent 25% of the course grade.
Texts, handouts, and/or workbooks will be determined by the TAE Department.
