Grading
Homework: 15%
Weekly quizzes: 20%
Midterm Exams: 40% (2 exams on 25 February and 11 April 2005)
Final exam: 25% (on 11 May 2005)

Homework, Quizzes and Exams 

Homework will be assigned weekly and will be graded based on submission and completion as described in "Grading Policy" below.  You must be present to turn in your homework and no late homework will be accepted.  Weekly quizzes will be one problem based on the homework that will be graded for correctness.  Midterm exams will be one hour long.  The final exam will last 90 minutes and will focus on new material but expect some cumulative material.

• 4: complete and mostly correct with strong attempts at all problems
• 3: mostly complete, good approach, some mistakes
• 2: incomplete or poor approach
• 1: incomplete and poor approach
• 0: nothing turned in

The course grade will be assigned based on the above grading distribution.  Exams will be normalized so that the mean for all three exams is the same.

Expectations of Students

• Students will take responsibility for their own learning. Students are responsible for all material, announcements, or changes made during class or on the course web page. Attending class and checking the web page regularly are encouraged.  While attendance is not graded, students who miss a lot of class will find it extremely difficult to get an A or even a B in the class.
• Students will prepare for class by reviewing previous material, reading the book and doing assigned homework.
• Students will clear up questions on exams during the exam period. Students are responsible for ensuring that their exams are not missing any questions or pages.
• Students will deal with conflicts in a timely manner. If you have some reason for missing an exam, you must talk with me before the exam or take a 0 on that exam.
• Students will wait 24 hours, but no more than 1 week, after receiving a graded assignment or exam before bringing up grading questions. Grades will be re-evaluated but are not negotiable.
• Students will bring up issues about final grades within two days of grades being released. Again, I will take requests for grade re-evaluations but final grades are not negotiable.
• Students will only ask for an incomplete grade in the case of exceptional circumstances and will furnish documentation that conforms to CIS Department regulations (illness requiring documented medical attention, documented death in the immediate family).
• Students will do and present their own work in compliance with the academic honesty policy.

Course Tools

• Password protected webpages: The Computer Science Lab computers host these pages.  The assignments and solutions will be available on the web but will be password protected.  Instructions for signing up for a password will be on the course webpage.

Disabilities
Students who may need accommodations for a disability can make an appointment to see me during my office hours to discuss your needs.

Academic Honesty
By staying enrolled in this class, you agree to abide by the University's Policy for Academic Honesty which appears in the Student Handbook under the section heading "Academic Honesty". If you have questions about the policy please contact me, your advisor, or another faculty member PRIOR to engaging in a "dishonest" act. Failure to abide and respect the Academic Honesty Policy will result in severe penalties as allowed by the University.  I want to point out to you the following expectation, which comes directly from the University's Statement of Student Responsibilities:

In order for an academic community to teach and support appropriate educational values, an environment of trust, cooperation and personal responsibility must be maintained. As members of this University community, students assume the responsibility to fulfill their academic obligations in a fair and honest manner. This responsibility includes avoiding such inappropriate activities as plagiarism, cheating or collusion. Students found responsible for one or more of these activities may face both academic sanctions (such as lowering a grade, failing of a course, etc.) and disciplinary sanctions (such as probation, suspension, expulsion).

It is the intent of Minnesota State University, Mankato to encourage a sense of integrity on the part of students in fulfilling their academic requirements. To give students a better understanding of behaviors that may constitute academic dishonesty, the following definitions are provided:

Plagiarism – Submission of an academic assignment as one's own work, which includes critical ideas or written narrative that are taken from another author without the proper citation. This does not apply only to direct quotes, but also to critical ideas that are paraphrased by the student.

Plagiarism includes but is not limited to:

• submitting the work of others as your own
• submitting others work as your own with only minor changes
• submitting others work as your own without adequate footnotes, quotations, and other reference forms
• multiple submission of the same work, written or oral, for more than one course without both instructor's permission, or making minor revisions on work which has received credit and submitting it again as new work.

Cheating — Use of unauthorized material or assistance to help fulfill academic assignments. This material could include unauthorized copies of test materials, calculators, crib sheets, help from another student, etc.

Collusion — Assistance to another student or among students in committing the act of cheating or plagiarism.
