Exam Protocol:

  1. Your cell phone and computer, plus all books and class notes, must be placed on the floor (not in your pant/shirt pockets) at the side of the room, front of the room, or back of the room. It is suggested that you not bring them.If you get caught using a cell phone during an exam, this will result in an automatic zero for this exam!
  2. A seating chart may be created, or be prepared for the instructor to assign you to particular seats before the exam begins.
  3. Students will not be allowed to leave room during an examination for bathroom breaks. Please use the restroom before you begin your exam. Once you leave the room, the exam will be collected as you will be done with the exam.
  4. Bring your UNT IDs to be checked.
  5. Arrive early to put your books, etc., away and to find your assigned seat.
  6. You will be given scratch paper and formulas will be part of the exam. You may also have a very basic nonprogrammable calculator. Cell phones cannot be used as calculators. The test is closed book so you may have no other materials at your desk.
  7. The instructor will quickly go over the test at the beginning of the period. Do not expect questions to be answered about the test while you are taking it.
  8. Absolutely no talking, looking on another student’s exam, or passing anything between students is permitted during the test. Such actions will be construed as cheating. Students are not permitted to leave the room during the exam. Suspicious activity will be noted on the seating chart. The test may be videotaped.
  9. Anyone finishing the test early must sit quietly until the end of the period. All tests will be taken up at one time.
  10. Five points will be deducted for each minute that a student continues working on a test after the instructor calls for them to be turned in.
  11. All attempts will be made to return the exam to you on the next class period. No exams will be given back outside of class. Please note that all exams will be scanned prior to returning them to the students.

Exam Grading Complaints: If you disagree with your grade on any test problem when the exam is returned, you must submit after that class a written statement on the back of the returned exam that clearly explains the reason you wish the problem to be regraded. Remember that only what you systematically wrote on the exam paper can be considered in grading a problem – not what you meant or claim to know. Moreover, answers that are submitted without supporting work will receive no credit. If a test is submitted for regrading, the entire test will be regraded (in case the instructor made a mistake grading other problems and gave you more or less points than you actually deserve). Finally, a student may request that an exam be regraded only on the day the exam is returned.

Missed Exams/Pop Quizzes: Do not count on the instructor to provide you with a make-up exam or make-up pop quizzes.. If you miss an exam, a Comprehensive Make-up exam will be administered on August 12, 2016 immediately after the final exam. Only one make-up exam will be given to replace one exam. No make-up pop quizzes (announced or announced) will be allowed. At any point of the semester, the instructor can decide to give extra credit assignments and/or pop quizzes. Extra credit can be expected to be applied toward the total grade points earned.

Late Assignments: It is the students’ responsibility to turn in all assignments on time and to develop the necessary work habits that are expected in the workforce such as meeting deadlines. Homework cannot be accepted late as it is controlled by the software.

Assignments: The homework assignments will be done using the WileyPLUS software. The assignments have a deadline. It is the student’s responsibility to meet this deadline. The deadline will not be adjusted to accommodate a student missing the assignment. The instructor does not always have the possibility of adjusting the software parameters once they are set.

Academic Dishonesty: All rules related to academic dishonestly will be enforced. DO YOUR OWN WORK! If a student submits a assignment similar to another student’s assignment, both of the students will receive a MINIMUM of a ZERO on that assignment. One for copying the assignment and the other one for letting the other student copy the assignment. Once you put your name on the assignment, you accept responsibility that it is your work!!

Disabilities Accommodation:

The University of North Texas complies with Section 504 of the 1973 Rehabilitation Act and with the Americans with Disabilities Act of 1990. The University of North Texas provides academic adjustments and auxiliary aids to individuals with disabilities, as defined under the law. Among other things, this legislation requires that all students with disabilities be guaranteed a learning environment that provides for reasonable accommodation of their disabilities. If you believe you have a disability requiring accommodation, please see the instructor and/or contact the Office of Disability Accommodation at 940-565-4323 during the first week of class.

Additional Policies and Procedures.

My commitment to the students is to train them to the best of my ability to compete in an ever changing technological world. I understand that these students need to be prepared to compete with students with many other higher educational institutions for positions and opportunities. Because of this, I will strive to ensure that the training that they receive is comparable (and may even be better) to the training that other students receive in other institutions . I also want to inform my students that my commitment to their success extends beyond graduation. I want to inform my students that my commitment in providing this training also extends to the community in which these students will eventually end up working in. Under no condition will I certify a student to be competent when he/she has not proven to have reached the level of competence needed to perform engineering work!

Just like I have a commitment to these students, I also have a set of expectations from these students. I expect the students to show up on time; to attend classes and labs regularly; to be respectful of other students , their teaching assistants, and myself; to turn in their assignments as scheduled, and to be ready to learn each and every time we meet. I expect all students to recognize that the teaching assistant that will be assigned for this class is a student who is working under my supervision. I expect all students to show respect and consideration to the laboratory teaching assistant at all times.

  1. All rules relating to academic dishonesty will be enforced in accordance with University policies. Cheating on quizzes, examinations and laboratory assignments, and plagiarism on various papers and reports are types of disciplinary misconduct for which penalties are assessed under the UNT Code of Student Conduct and Discipline. Major responsibility for implementing the University's policy on scholastic dishonesty rests with the faculty. Be advised that the instructor of this course supports and fully implements this policy. The following actions will be taken when evidence of such misconduct is observed. The student will be presented with the evidence of misconduct and given an opportunity to explain same. Based on the outcome of this private conference, the matter will be either dropped or the student will be given a grade of "F" in the course and be referred to the Dean of Students for further counseling and/or disciplinary action.
  1. State common law and federal copyright laws protect my lectures. They are my own original expression and I record them at the same time that I deliver them in order to secure protection. Whereas you are authorized to take notes in class thereby creating a derivative work from my lecture, the authorization extends only to making one set of notes for your own personal use and no other use. You are not authorized to record my lectures, to provide your notes to anyone else or to make any commercial use of them without expressed prior permission from me.
  1. During the course, handouts will be provided to enhance the presentation of certain concepts. These materials are provided strictly for instructional purposes and may otherwise be restricted. There is no authorization for further reproduction of distribution of handout materials beyond that intended to teach the course.
  1. This syllabus is subject to change at any time during the semester with changes to be announced in class.
  1. Students should schedule at least one hour per lecture hour for study outside class. Students should schedule at least one hour per laboratory hour for outside work to prepare for the laboratory, use of open laboratory hours, and to complete the required laboratory documentation.
  1. Grades are based, in part, on the student's ability to communicate. Well written English is expected in all course work and is a factor in laboratory report grades. The student’s ability to orally communicate the results of laboratory exercises and class assignments is also monitored.
  1. Each student should retain graded lecture notes, pop quizzes, homework, tests, software-generated files, and laboratory reports to document errors in recorded grades.
  1. Requests for review of graded work must be submitted during the lecture in which such work is returned to the students. The request should be accompanied by a written justification of the request including any supporting data.
  1. The UNT Catalog procedures on cheating and plagiarism will be vigorously enforced. It is the duty of all students to protect their work so it is not available to others for submission as their efforts. This is especially true of files that are generated on the computer. Students who knowingly allow others to use their work are partners in this unethical behavior.
  1. There is no limit to the use of calculators for lecture, labs, pop quizzes, formal tests, or final examination.
  1. Challenges to the course grade must be presented within 30 days of receipt of grade notices mailed by the university. This will insure that instructor’s records are still available to allow a review of the assigned grade. You should first discuss your complaint with the instructor. If you wish to carry it further, contact the Program Coordinator by calling (940) 565-2022. To further pursue your complaint, contact the Department Chair at (940) 565-2022, but ONLY after first discussing your concern with the previous two individuals.
  1. If appropriate, Material Safety Data Sheets (MSDS) are maintained on file in the department for your review. Access to these documents may be provided by the:
  • instructor of this course,
  • Program Coordinator, or
  • Department Secretary.

Seek initial access through the instructor or Coordinator rather than the secretary.

  1. An I (incomplete) grade is given only for extenuating circumstances and in accordance with University and Departmental Policies.
