Methods of Instruction & Active Learning
Instructional Method(s):
- Lecture
- Laboratory / Studio / Shop / Clinical
- Discussion
- Tutorial
- Technology
- Other
Examples: Lab topics include safety practices while working within an industrial area/shop. Labs will cover basic content theory of gas tungsten arc welding of the basic joints.
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. The instructor continuously demonstrates the proper use of the welding equipment and related tools. Students perform welding demonstrations for the instructor's approval.
Discussions go on constantly between the student and instructors as to the proper settings and adjustments for the welding machines and filler wires 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.
Execution of demonstrations provided by the instructor on the proper use of equipment and tools, as applicable to each of the welding processes, is a continuous practice. Group, as well as one on one performance examples are utilized for the student to observe accurate Welding technique in order analyze any deviations from their own methods. Additionally, student skill development is monitored and advanced through observation of students demonstrating their acquired skill-sets as they progress.
An instructional aide will assist the students with welding techniques in the welding lab.
Students will access course material through CANVAS.
Students are encouraged to become a member of the American Welding Society (AWS). On a regular basis, AWS provides literature on new and changing areas of welding. AWS provides meetings with the local welding shops / members and demonstrates the latest in welding technology.
Students are encouraged to make full use of the Learning Resource 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)
Assignment for In and Out of Class
Assignment Types:
- Substantial college level reading assignment, such as: textbook, journal article(s), literature, and/or other (specify)
- Lab or field activity, product, and/or report
- Class Presentation
- Portfolio
Examples: Students will read trade-related publications, website documents pertaining to welding and handouts. The Instructor will assign welding videos to watch and other online activities that can be access through their Canvas LMS account.
Students are given a specific project for each welding process to complete each time they are in class. The project given will depend on the students' abilities and knowledge of the welding process. This will allow teaching of all levels of welding from beginning to advance, within one lab environment.
Students may often make an informal presentation to the class on safety issues, work difficulties and successes, which they might have encountered during a laboratory assignment as an exercise in meeting the course learning outcomes
Students are continually asked to up-grade their resumes to include their present experience.
Methods of Evaluation
Written Evaluations:
- Laboratory Report(s)
Examples: Students are to comply with their Basic English/Writing skills when completing their assignments. They are to submit a complete and correct set of documents in a timely manner. The instructor will evaluate, grade and return to the student with suggestions for improvements.
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).
