Grading Standards


Grading          Grades will be assigned as follows (unless otherwise noted):

Scale:             A: 90-100%; B: 80-89%; C: 70-79%; D: 55-69%; F: <55% (of total points)

Submission Format Policy

Note: You may not submit a paper for a grade in this class that already has been (or will be) submitted for a grade in another course, unless you obtain the explicit written permission of me and the other instructor involved in advance.

Late Paper Policy

Under no circumstances will make-up exams or extra assignments be given. One missed exam may be made up based on the comprehensive final exam (substitute final exam score for the missed exam score) if unavoidable medical circumstances exist.

The evaluation of student material is the domain of the instructor. Standard grading policy is followed without exception. Exam errors will be handled by removing the required points from the exam total, but credited if answered correctly for multiple choice format questions. The class average will be determined by the performance of the class with adjustment to an average of 64%. We will adhere to MSU’s standard policy. Refer to the MSU website calendar for any important campus-wide dates, such as the final exam date.

Questions about the grading of any assignment should be brought to the instructor within one week after the assignment is returned. Scores are reported after each exam.

Plagiarism Policy

Plagiarism is the use of someone else's thoughts, words, ideas, or lines of argument in your own work without appropriate documentation (a parenthetical citation at the end and a listing in "Works Cited")-whether you use that material in a quote, paraphrase, or summary. It is a theft of intellectual property and will not be tolerated, whether intentional or not.

Student Honor Creed

As an MSU Student, I pledge not to lie, cheat, steal, or help anyone else do so."

As students at MSU, we recognize that any great society must be composed of empowered, responsible citizens. We also recognize universities play an important role in helping mold these responsible citizens. We believe students themselves play an important part in developing responsible citizenship by maintaining a community where integrity and honorable character are the norm, not the exception.

Thus, We, the Students of Midwestern State University, resolve to uphold the honor of the University by affirming our commitment to complete academic honesty. We resolve not only to be honest but also to hold our peers accountable for complete honesty in all university matters.

We consider it dishonest to ask for, give, or receive help in examinations or quizzes, to use any unauthorized material in examinations, or to present, as one's own, work or ideas which are not entirely one's own. We recognize that any instructor has the right to expect that all student work is honest, original work. We accept and acknowledge that responsibility for lying, cheating, stealing, plagiarism, and other forms of academic dishonesty fundamentally rests within each individual student.

We expect of ourselves academic integrity, personal professionalism, and ethical character. We appreciate steps taken by University officials to protect the honor of the University against any who would disgrace the MSU student body by violating the spirit of this creed.

Written and adopted by the 2002-2003 MSU Student Senate.

Students with Disabilities

The Americans with Disabilities Act (ADA) is a federal anti-discrimination statute that provides comprehensive civil rights protection for persons with disabilities. 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 an accommodation, please contact the Disability Support Services in Room 168 of the Clark Student Center, (940) 397-4140.

Safe Zones Statement

The professor considers this classroom to be a place where you will be treated with respect as a human being - regardless of gender, race, ethnicity, national origin, religious affiliation, sexual orientation, political beliefs, age, or ability. Additionally, diversity of thought is appreciated and encouraged, provided you can agree to disagree. It is the professor's expectation that ALL students consider the classroom a safe environment.

Contacting your Instructor

All instructors in the Department have voicemail in their offices and MWSU e-mail addresses. Make sure you add your instructor's phone number and e-mail address to both email and cell phone lists of contacts.

Attendance Requirements

Attendance to lecture is required.  Students are responsible for all material presented in class and in assigned material. In-class exercises will not be provided outside of class.[1]

[1] Refer to the MSU handbook for University policies about academic honesty and class attendance

Other Policies

Calculators with large memory capacity, mathematical solution software, and chemistry software are NOT allowed on exams. The use of such a calculator on an exam constitutes cheating. (single-line scientific calculators are acceptable). I may check the memory of any calculator during an exam.

Cell phones, computers, PDA’s and other electronic devices are NOT allowed during class. Cell phones must be OFF during any scheduled class period.

Writing Proficiency Requirement

All students seeking a Bachelor's degree from Midwestern State University must satisfy a writing proficiency requirement once they've 1) passed the 6 hours of Communication Core and and 2) earned 60 hours. You may meet this requirement by passing either the Writing Proficiency Exam or English 2113. Please keep in mind that, once you've earned over 90 hours, you lose the opportunity to take the $25 exam and have no option but to enroll in the three-credit hour course. If you have any questions about the exam, visit the Writing Proficiency Office website at, or call 397-4131.

Campus Carry

Senate Bill 11 passed by the 84th Texas Legislature allows licensed handgun holders to carry concealed handguns on campus, effective August 1, 2016. Areas excluded from concealed carry are appropriately marked, in accordance with state law. For more information regarding campus carry, please refer to the University’s webpage at

If you have questions or concerns, please contact MSU Chief of Police Patrick Coggins at
