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 CSU Transferable Methods of Evaluation Projects Example: Major student projects will be graded according to completeness, adherence to building codes, and industry standards. The grading is determined by a grading rubric. Example: Wiring of a 3-way switching of a light. Skill Demonstrations Example: Students will analyze electrical systems according to the plan specifications and evaluate to California Electrical and National Electrical Code standards. The grading is determined by a grading rubric. Repeatable No Methods of Instruction Laboratory Lecture/Discussion Distance Learning Lab: 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. (Laboratory Objective 2) Lecture: Instructor will lecture on the California Green Technology and "Net Zero Energy" policies related to new and remodeled electrical construction. The student will be given an opportunity to clarify any questions in an instructor-guided discussion. (Lecture Objective 6) Distance Learning Students in online classes participate, individually and in groups, in discussion boards and respond to weekly assignments via the Learning Management System. The instructor will provide documented material (including videos) explaining or exploring the course content and provide individual feedback on all assignments. Instructor will demonstrate proper wiring techniques via online conferencing tool and record the session for asynchronous participation. students will demonstrate understanding by responding to discussion post, submitting a student led instructional video or slideshow, and/or an image of their completed wiring assignment. (Lecture Objective 5) Typical Out of Class Assignments Reading Assignments 1. Read and answer chapter-ending questions on National Electrical Code from textbook. 2. Read instructor provided handouts to be prepared for in-class discussions on local building codes. Writing, Problem Solving or Performance 1. Calculate wire sizes determined through amperage calculations for electric dryer. 2. Pull wire to service all receptacles in a circuit.
