Course Requirements:

1. Students must abide by the Honor Code - The University of Maryland, College Park has a nationally recognized Code of Academic Integrity, administered by the Student Honor Council. This Code sets standards for academic integrity at Maryland for all undergraduate and graduate students. As a student you are responsible for upholding these standards for this course. It is very important for you to be aware of the consequences of cheating, fabrication, facilitation, and plagiarism. For more information on the Code of Academic Integrity or the Student Honor Council, please visit http://www.shc.umd.edu. To further exhibit your commitment to academic integrity, remember to sign the Honor Pledge on all examinations and assignments: "I pledge on my honor that I have not given or received any unauthorized assistance on this examination (assignment). "
   
   
2. Students must be present at the designated time and for the duration of class. Students are responsible for all materials presented in class in addition to the reading assignments. Instructions, announcements about course changes and demonstrations will be given at the beginning of each class as appropriate.
   
   
3. Students are expected to be in class for the scheduled time. DO NOT obligate yourself for activities (work, social, medical non-emergencies) that conflict with scheduled class time. All class assignments missed because of other approved field trips are to be completed/planned for before the trip. Please advise the instructor if you are going to be absent.
   
   
4. If you have a documented disability and wish to discuss academic accommodations with me, please contact me as soon as possible.
   
   
5. If you have any type of medical condition or any other disability which may affect your safety or the safety of others around you while operating machinery, please contact me individually. Examples include fainting spells, seizures, taking OTC or prescription medications which may impair you ability to operate equipment.
   
   
6. Proper attire is required for lab exercises. This includes long pants, long sleeve shirt, safety glasses or goggles meeting ANSI Z87 or ANSI Z87.1 specifications, and appropriate safe clothing including hard top shoes for all lab sessions. Specific eye protection for welding applications will be provided in class.
   
   
7. Laboratory exercises - will be evaluated by the instructor with the expectation of a grade of "B" or better. Lab exercises may be repeated with the higher score replacing any lower score.
   
   
8. Exams (mid term and final) will be announced. The final exam is announced in the University of Maryland course schedule. A calculator may be used for the completion of any math problems, but full credit will only be given when the total solution is shown. (Always show your problem solving procedure for full credit.)
   
   
9. Quizzes may or may not be announced. Material included may be from current lectures or current class assignments (readings, video, etc.)
   
   
10. Written assignments or exercises may include but are not limited to:
    • laboratory or clasroom exercises
    • electronic communications assignments
    • questions and answers on reference and text materials
      
      
11. Calculation of your final grade:
    • 40% lab exercises
    • 15% midterm exam
    • 15% final exam
    • 20% written activities, quizzes, homework, electronic assignments, etc.
    • 10% Term Project
      
      
12. Course letter grades will be assigned on the following basis with +/- grades to be posted:

    A: 90% - 100%

    B: 80% - 89.99%

    C: 70% - 79.99

    D: 60% - 69.99 % 

    F: below 60%
    
    

13. Current grades will be posted during the semester via an alias number assigned to you.
    
    
14. Students are expected to turn materials/assignments in on time. Unexcused late materials will loose 10% of assigned points per normal class day late. Late assignments will not be accepted after those that have been graded have been returned to students. All assignments must be completed by the last day of class.
    
    
15. Academic dishonesty (cheating, fabrication, facilitating academic dishonesty, plagiarism) will be dealt with in accordance with established University policies.
