  2. Use industry specific terminology to explain or discuss motor operations with industry professionals.
  3. Demonstrate safe working conditions in accordance with state and federal regulations. *

* required for Statewide Apprenticeship Degree
 


 

Course Activities and Design

A lecture-laboratory course in which the student may come from a wide variety of occupations.  The emphasis of the course activities will depend on the needs of the students.  Laboratory activities will utilize electrical test equipment to analyze electric motor control malfunctions. Students are required to supply their own meter.
 

Outcome Assessment Strategies

Procedures will be discussed at the first class session and the instructor's grading policy will be reference on the class syllabus.  Assessment will be based on attendance, participation, homework, lab activities and assignments, short quizzes and written examination.
