Measurement of Learner Outcomes
(1) Written Examination
(2) Practical Evaluation – Students will be asked to show competence by kinesthetic demonstration.
(3) Verbal – Students will demonstrate competence by presenting oral demonstrations in groups and individually.
Students will be tested for knowledge and skill attainment through written tests comprised of questions taken from handouts, reading assignments, homework and lectures. Quizzes may be unannounced, but tests will be announced at least one class period before they are given. For the laboratory assessments, the students will demonstrate his or her ability to produce satisfactory welds, set forth by the instructor. These welds will be judged for soundness and quality as set forth by the American Welding Society’s D1.1 Structural Welding Code, which is the standard in this country and throughout the world.
Method of Instruction
A combination of lecture, discussion, demonstrations and film/video presentations will be used in the classroom training. Hands-on training will be in the welding lab. The student will make quality welds in the horizontal, vertical, and overhead positions on both fillet and groove welds.
Course Requirements
Students will be required to pass the welding safety test with 100% accuracy before they will be allowed to work in the shop.
Safety principles in the weld shop will be followed at all times.
Students will complete training on all needed welding and cutting equipment.
Students will be required to hand in homework assignments by due date.
Students will be required to hand in shop assignments.
Students will be required to hand in class assignments.
Lab Assignments: The students will demonstrate:
The ability to weld with the SMAW process on various joint designs, with various welds, in various positions. Job descriptions are described in the student textbook.
Perform setup, cutting techniques and shutdown with the Carbon Arc Cutting process.
NO CELL PHONES, MP3 PLAYERS, CD PLAYERS, ETC. WILL BE ALLOWED IN THE CLASSROOM OR THE LAB EXCEPT AS PERMITTED BY THE INSTRUCTOR.
Attendance Policy:You are expected to attend all class meetings. Exceptions may be discussed with the instructor with suitable make-up activities agreed upon (before the absence). All course work is due on the assigned dates whether or not you are present. You will lose one letter grade for every day (not class period) that it is late. The instructor assumes no responsibility for making sure you receive any course material for which you were absent. This is your responsibility.
After being tardy three timesthis will count as one absence. If you are tardy morethan one hour this will count as a half day absence, andif two and a half hours late or more this counts as an absence. AFTER TWO ABSENCES YOU WILL BEDROPPED FROM THE CLASS.
Students with Disabilities:GBC supports providing equal access for students with disabilities. An advisor is available to discuss appropriate accommodations with students. Please contact the Director for Services to Students with Disabilities (Julie Byrnes) in Elko at 775.753.2271 at your earliest convenience to request timely and appropriate accommodations.

Plagiarism
Plagiarism is presenting someone else’s words, ideas, or data as one’s own. When a student submits work that includes the words, ideas, or data of others, the source of that information must be acknowledged through complete, accurate and specific references, and if verbatim statements are included, through quotation marks as well. In academically honest writing or speaking, the student will acknowledge the source whenever another person’s actual words are quoted, whenever another person’s idea, opinion, or theory is used, even if it is completely paraphrased in the student’s own words, or whenever facts, statistics, or other illustrative materials are borrowed, unless the information is common knowledge.
