Examples: LECTURE:
Lecture topics include safety practices while working within an industrial area/shop. Lectures will cover basic content theory of SMAW flat/horizontal open root groove welds.
LABORATORY/STUDIO/SHOP/CLINICAL:
Students will work closely with the instructor while learning the proper way to setup and operate the welding equipment. Advanced students will assist the beginners and may work as a team or work individually.
DEMONSTRATION:
The instructor continuously demonstrates the proper use of the welding equipment and related tools. Students perform welding demonstrations for the instructor’s approval.
DISCUSSION:
Discussions go on constantly between the student and instructors as to the proper settings and adjustments for the welding machines and the electrodes used. Discussions also cover workplace safety, wages and working conditions in industry. Student-to-student discussions occur in the lab environment and will cover content information and problem solving.
TECNOLOGY:
Students are encouraged to make full use of the Technology Center (Tech Center) for research on jobs and employer expectations. They are also encouraged to use the Tech Center to advance their Secretary’s Commission on Achieving Necessary Skills (SCANS).
VIDEO PRESENTATION:

Diversity, Equity, Inclusion, Accessibilty
Instruction through the Course Outline of Record includes approaches to teaching that promote inclusion and engagement with diverse bodies of students using methods that are inclusive of diverse perspectives, close equity gaps, and are accessible to all students.
Teaching faculty participate in college-wide efforts to close equity gaps, such as course-level data validation in program planning, centers and communities for teaching, DEIA professional development activities, and Student Learning Outcomes assessment.
Cyclical Routine Review of course objectives, outcomes, content, assignments, methods of evaluation, methods of instruction, representative textbooks and materials, and requisites allows faculty to explore how each element of the course outline illustrates inclusion and engagement with diverse student bodies.
Course instruction is accessible to all students, including those with disabilities, and is achieved through professional development support, and District accessibility procedures which guarantee accommodation so that all students can equally participate in learning opportunities.
Design of instructional materials, including those hosted online in learning management systems, can be reviewed for accessibility through accountability systems such as the CVC@ONE's Peer Online Course Review and in collaboration with the college’s Instructional and Universal Designer, who assists faculty in the design and implementation of materials and strategies that meet best practices for Accessibility and Universal Design for Learning (UDL).
