Homework
Expect to spend at least two hours on homework per one hour of class time. This
means that you should be spending at least 10 hours per week on homework
especially if you struggle with mathematics. Homework deadlines will be
announced in class and on the course website. Late homework will not
be accepted for any reason, so do not procrastinate and be sure to submit your
homework promptly. Homework papers placed in my mailbox also will not be
accepted. About five or six homework sets will be assigned. Your lowest homework
score will be dropped from your overall grade. The teaching assistant will be
instructed to deduct points or give a grade of zero if the following instructions are
not followed:
2• The homework solutions you submit should be written neatly and in an or-
ganized manner. As you present a solution, it should be easy for a reader
to follow how one step leads to another. The examples in the text are good
guides to follow in this regard, as are any examples I may work in class. Some
problems may be difficult and require multiple attempts before finding a suc-
cessful strategy. Use scratch paper for preliminary work, and only include the
successful attempt on your submitted homework. Papers containing sloppy
and illegible work will not be graded. This includes papers with scribbles.
• Your solutions should be clearly labeled and in order. If multiple sheets of
paper are required to complete an assignment, they must be COLLATED
and STAPLED together. I advise that you use loose-leaf paper to write your
solutions on. If you wish to use notebook paper, be sure that all fringes
are completely removed before you submit your assignment. Please write
your name and the assignment number on the front page.
• Your written solutions should contain enough explanation so that the grader
is convinced that you know what you are doing. Generally, it is inadequate to
merely write down the final answer to a problem.
• You are encouraged to work together on homework assignments. However,
each of you must submit your own assignment. Everything you submit should
be in your own words and you should thoroughly understand everything you
write down. Offering and accepting solutions from others is an act of pla-
giarism, which is a serious offense and all parties involved will be penal-
ized according to WSU’s Academic Integrity Policy.
Quiz Policy
There will be quizzes given during each Thursday class, except during exam weeks.
The problems will be similar to homework and examples done in class. No make-
up quizzes will be given. Please write neatly in pencil, show all of your steps, and
circle (or box) your final answers on all quizzes. Unless stated otherwise, notes,
books, and electronic devices (including calculators) are not allowed on any quiz.
Exam Policy
There will be a midterm exam and a comprehensive final exam. Students must
bring a valid ID to each exam. All exams must be taken during their
scheduled date and time. There will be no make-up exams unless a stu-
dent can provide verifiable evidence that he/she has a significant illness or serious
family crisis that will prevent him/her from attending. Except under extremely
unusual circumstances (i.e. jail or car accident), you must inform me in advance
of the missed exam. In the event that this happens, you are expected to promptly
make arrangements with me to make up the exam. Please write neatly in pencil,
show all of your steps, and circle (or box) your final answers on all exams. Unless
stated otherwise, notes, books, and electronic devices are not allowed on any exam.
3Expectations
• Respect your classmates, yourself, and your instructor.
• Attendance and active participation is highly expected as it is critical to your grade.
Show up to class on time and come prepared, i.e. bring paper and a pencil at the
minimum.
• All cell phones, pagers, MP3 players, and other noise makers must be kept silent during
the entire class period. A repeated pattern of classroom interruptions by electronic
gadgets will be considered grounds for discipline.
• Any disruptive behavior will not be tolerated as this detracts from the learning envi-
ronment.
• Any form of cheating will not be tolerated. If you are caught cheating during a quiz
or exam, then your quiz/exam will be taken from you and you will receive a 0% for
that particular quiz/exam and possibly the course. In other words, academic honesty
is expected and will be enforced.
• I insist on the use of a pencil for all mathematical work. In mathematics, mistakes
occur, but I expect you to be able to erase these mistakes on homework, quizzes, and
exams.
Tutoring
The Math Learning Center (MLC) is an ideal place to work on homework between
classes if my office hours are not sufficient. It is a supportive place for students to come
together and study in groups or individually. Tutors are available to help you solve
problems and improve your math skills. The MLC is located in Cleveland 130.
The MLC Summer Session weekly hours are: 10:00 am to 5:00 pm from
Monday to Thursday.
Students with Disabilities
Reasonable accommodations are available for students with a documented disability.
If you have a disability and need accommodations to fully participate in this class,
please either visit or call the Access Center (Washington Building 217; 509-335-3417)
to schedule an appointment with an advisor. All accommodations MUST be approved
through the Access Center.
An Invitation
If you have any questions on homework, questions/concerns about the course, concerns
about your grade, etc, please see me during my office hours or make an appointment
to see me.
NOTE: I reserve the right to add-to or modify the information contained on this syllabus
