Course Requirements and Procedures: Lectures: 1) Lectures will be conducted in the Howe Bldg, Room 155, beginning promptly at 8:00 am on Mondays. 2) Each student is responsible for announcements, written/verbal notes given, exams, quizzes and worksheets given during lecture. 3) Attendance will be recorded at the beginning of each lecture period. You will not be permitted to makeup-missed exams, quizzes or worksheets due to an unexcused absence. 4) Any out-of-class work assigned must be completed and turn in on the due date assigned. Major work will be accepted with a 10 point/day late penalty, including weekends.

Labs: 1) Labs will be conducted in the Agricultural Mechanics building, Main Lab Area Wednesday and Friday mornings. The length of each welding lab is four hours-8:00-11:50 am. 2) Attendance is just as important as completing any lab assignments. Attendance is required. A sign- in & out sheet will be located at the front entrance of bldg. Attendance will become a part of the evaluation grading system. Cleanup grade will be recorded for each lab period. 3 3) Students are required to complete all lab skills assigned. Failure to complete any lab skill will be graded accordingly. Use lab time wisely. 4) Dress appropriately for lab work. Occasionally, clothing may need cleaning during the semester. 5) Safety glasses must be worn in lab at all times. To insure that all students wear safety glasses in lab, 5 points for each violation that occurs in lab will be deducted from one hundred (100) points. 6) Cleanup – Cleanup and returning tools to its proper place, are just as important as performing the skills itself. Ten (10) points will be deducted for each lab period, when not cleaned or tools placed in their proper place.

7) Scorecards and procedures are available for each assigned lab skills. Read carefully and follow instructions. Once skill is completed, place your skill in a designated area, determined by the instructor, with your name printed on the skill with a designated paint pencil.

Safety: “Our primary consideration during lab work is safety” “Think smart!” Materials supplied by students: Industrial Quality Safety Glasses: Industrial quality eye protection (conforming to ANSI Z87 standards) is required for all labs unless otherwise indicated by your instructor. You will lose credit in lab and may not be allowed to attend some labs without safety glasses covering your eyes. Safety glasses may be purchased at the bookstore or at local hardware stores. The shop and its equipment are color coded according to the Recommended Safety colors for agricultural science laboratory. Each color represents a safety reminder. It is the responsibility of the student to learn the color-code system.  Vista green – basic structure of equipment  Safety orange – electrical switches, guards/covers for moving parts  Safety red – vises or things that will crush  Safety blue – electric motors and control boxes  Ivory – denotes edges of equipment and tables Welding Gloves: Welding gloves may be purchased at local welding stores. Gloves must be of the gauntlet-style and suitable for welding.

Other Safety Concerns: 1) Do not disturb others while they are operating power machinery. 2) Do not operate power equipment yourself unless you are familiar with the operating procedures and safety rules of power equipment. 3) When operating power equipment, place full attention on the job before you. 4) Do not operate power equipment, when you feel ill or excessively preoccupied. 5) Follow all safety rules and procedures. Failure to follow rules will result in loss points in lab grades.

Assessment - Method(s) of Evaluation and Grading Procedures Criteria for the evaluation of students will be 50% lecture grades and 50% laboratory grades. Grades will be computerized according to percentage. 90-100%=A; 80-89%=B; 70-79%=C; 60-69%=D; below 60%=F. Lecture Grade will include: a) 5 - Major exams (including final) b) Quizzes, worksheets, etc will be given at the beginning of each lecture period, excluding major exam period. c) Participation in FFA Ag. Mechanics Contest

Laboratory Grade: a) Skills Note: All lab skills will be graded according to a scorecard. b) Cleanup will be graded by a lab assistant. Ten points per lab period. ALL students are responsible for cleanup. c) Safety – 100 points (deduction of 5 points each time safety glasses are not worn during lab period). Policies for Attendance, Excused Absences, Make-up Exams and Late Assignments: Successful performance in this class requires that you attend class. This class will meet 16 times during the semester. Four class periods are used for testing, excluding the final exam. Daily exam and or assignment sheet (5 minutes) will be given at the beginning of each class period. Make-ups for missed exams are granted only for excused (official university) absences. No late assignments will be accepted. A zero will be 4 recorded for lateness. Graduating seniors who need to schedule an early final should inform the instructor early in the semester. Classroom Policies: Students will turn off or put their cell phones in silent mode during the regular lecture period, lab excluded. Each student is responsible for any announcements or information given in lecture/lab periods. Disability Statement: (See pages 2 & 11 of the Student Handbook) Students with disabilities, including learning disabilities, who wish to request accommodations in class, should register with the Services of Students and Disabilities (SSD) early in the semester so that appropriate arrangements may be made. In accordance with federal laws, a student requesting special accommodations must provide documentations of their disability to the SSD coordinator. For more information, call 361-593-3024 or visit Life Services and Wellness Center at 1210 Retama Drive. Academic Misconduct: (See page 23, section 100 of the Student Handbook) You are expected to practice academic honesty in every aspect of this course and all other courses. Make sure you are familiar with your Student Handbook, especially the section on academic misconduct. Students who engage in academic misconduct are subject to university disciplinary procedures. Forms of academic dishonesty are:  Cheating –deception in which a student misrepresents that he/she has mastered information on an academic exercise that he/she has not mastered; giving or receiving aid unauthorized by the instructor on assignments or examinations.  Academic misconduct—tampering with grades or taking part in obtaining or distributing any part of a scheduled test.  Fabrication—use of invented information or falsified research.  Plagiarism—unacknowledged quotation and/or paraphrase of someone else’s words, ideas, or data as one’s own in work submitted for credit. Failure to identify information or essays from the Internet and submitting them as one’s own work also constitutes plagiarism. Nonacademic Misconduct: (See page 23, section 100 of Student Handbook) The university respects the rights of instructors to teach and students to learn. Maintenance of these rights requires campus conditions that do not impede their exercise. Campus behavior that interferes with either…  The instructor’s ability to conduct the class,  The inability of other students to profit from the instructional program, or  Campus behavior that interferes with the rights of others… will not be tolerated. An individual engaging in such disruptive behavior may be subject to disciplinary action. Such incidents will be adjudicated by the Dean of Students under nonacademic procedures. Sexual Misconduct: (See page 23, section 200, of Student Handbook) Sexual harassment of students and employers of Texas A&M University-Kingsville is unacceptable and will not be tolerated. Any member of the university community violating this policy will be subject to disciplinary action.
