General Education Information Approved College Associate Degree GE Applicability CSU GE Applicability (Recommended-requires CSU approval) Cal-GETC Applicability (Recommended - Requires External Approval) IGETC Applicability (Recommended-requires CSU/UC approval) Articulation Information Not Transferable Methods of Evaluation Objective Examinations Example: Students will answer questions on basic electrical theory, electrical practices, and codes. Example: Describe the difference between AC and DC. Points will be assigned to each question and converted to a letter grade. Skill Demonstrations Example: Students will demonstrate correct wiring and installation techniques, safe use of various meters, diagnostic tools and equipment, follow proper installation procedures, and observe OSHA safety protocols. The grading is determined by a grading rubric. Repeatable Yes Methods of Instruction Laboratory Lecture/Discussion Lab: Instructor will lecture on typical methods of electrical circuit sizing and installation. The student will be given an opportunity to clarify any questions in an instructor-guided discussion. (Lecture Objective 12) Lecture: Lab techniques will be presented in a "describe / show / review" methodology. Students will complete a safety test before using equipment. Instructor will work with students until they can successfully complete the test with 100% success rate. (Lab Objective 1) Typical Out of Class Assignments Reading Assignments 1.
