Intended Outcomes for the course


Course Activities and Design

This is a competency-based course utilizing a lecture/lab format. This course includes classroom discussions, video tapes, and lab demonstrations covering technical skills. Course competencies will include; theoretical concepts, layout, fabrication, welding, oxyfuel cutting, safety and environmental awareness, communication, applied Math and Science and human relations.

Outcome Assessment Strategies

At the beginning of the course, the course syllabus will identify the methods used to evaluate student progress and the criteria for assigning a course grade. The student will be evaluated on his/her ability to demonstrate the development of course competencies. The methods of evaluation may include one or more of the following: oral or written examinations, quizzes, written assignments, welding tests, safe work habits, task performance, and work relations.
