Submission Format Policy


Homework is due at the beginning of each class period.  No late homework is accepted, except possibly in the event of an excused absence.  A student who is absent may turn his/her homework in by faxing it to the attention of the instructor at 940-397-4442, or by scanning it and sending it through email to  Homework must be faxed or emailed  by the beginning of class to avoid being late.


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

Homework:   Late homework will not be accepted, except possibly for an excused absence.

Exams:  No make-up exams will be given.

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

Since this course relies heavily on group participation, unexcused absence from class or excessive late arrivals to or early departures from class will lower your final grade.  In addition to regular class attendance, participation in class is essential (e.g. during class you will work in groups to solve a variety of problems and you will be asked to share your thoughts on the mathematical task within these problems, including solution methods, both in your groups and at the board). For each unexcused absence, your participation grade will be lowered by 5 points. Excessive late arrivals or early departures from class will count as unexcused absences.  For extreme circumstances, in which the instructor is convinced that an absence was unavoidable, the instructor may consider an absence to be excused.  It is the responsibility of the student to discuss any such absence with the instructor, as well as, when requested by the instructor, provide documentation supporting the reason for the absence.  In addition to working problems within groups in class, you will be assigned problems to complete at home.  Regularly, you will be asked to share your solutions to problems in your group or with the entire class.  For each class meeting in which you have not prepared sufficiently (i.e. do not have your written assignments for sharing), your participation grade will be lowered by 3 points.
