You do not have the option of making other time arrangements for taking the exams or the final.
You will be instructed as to what you need to bring for each exam. Lab information may be included on any of the exams.
Course Net Site: This syllabus specifies policies applicable to Math 2355. Additional information can be found at
http://www.uwyo.edu/cvadnais/2355.html. Each week the Excel computer labs will be posted to this course net site. Additionally
numerous other documents will be posted to the course net site over the semester.
Grading:
You have two grading options to choose from. Clearly in a class this large there is a diversity of learning styles.
These options adapt the grading to reflect these learning styles. If you want option B do nothing. You only
need to come see me, at my office, if you are going to choose option A, and then you must do so by noon,
February 8th.
Option A is for those students who do well on their own (and know they will do well) and do not stress during a testing
situation. Do not choose this option just because you do not want to go to the discussions. Very few people should
choose this option. Those who decide on this option and aren’t sure that they should, may be setting themselves up for
failure!
Option B is for those students who learn best in a classroom setting and/or tend to stress during testing. The majority
of you should be choosing this option. Any student repeating the course will choose option B.

Discussions
 Each Tuesday discussion section will be devoted to answering questions concerning problems sets assigned from the book
(those listed on the last page of this syllabus) and clarifying concepts presented in lecture. Do the book homework and
come with questions.
You are expected to bring your book, notebook & calculator and be prepared to work. The time will not be devoted to having
The discussion leader lecture over the material I already covered. Other problems from the book, besides those assigned, may
be looked at. I expect you to be proactive!
A quiz will be given during the last 10 minutes of each discussion. Each quiz will be worth 10 points.
You must be in class the whole time if you wish to take the quiz. No take home or group quizzes will be given. Occasionally
notebook problems may be looked at for part of your quiz score.
Your 3 lowest quiz scores will be dropped at the end of the semester.

Each Thursday lab will consist of a computer lab using Microsoft Excel.
The labs can be found at the net site (see page 1). Due dates are listed on the course calendar and on each lab.
You will be doing 11 labs during the semester. Lab 1 is for extra credit points. None of the remaining lab scores will be
dropped. All parts of each lab will be graded. Be sure to read the first page (Important Information) for lab1. It contains
directions concerning all of your labs.
You are to do each lab on your own.
Finished computer labs can be left on the desk at the front of class during large group lectures, placed in the mail slot
down the hall from my office (across the hall from Ross 207 – at the end of the couch), or given to me in my office. Your
discussion leader does not collect these. Labs DO NOT go in my department mailbox or under my office door. Any that
show up in my department mailbox or under my office door will receive an automatic grade of zero.
Labs are due by 8:30am each Friday. The due date and time is listed on the lab and the course calendar. No late
labs are accepted unless you have a university excused absence. You need to get the lab turned in ahead of time if you
will be absent on the due date.
Homework Notebook
Your homework notebook consists of your completely hand worked book problems, listed on the syllabus.
You must use a spiral or perfect bound notebook. Feel free to use the front and back of each page.
Each set of problems for a particular section must be worked out in sequential order, one column wide. This means that if you
don’t know how to do a particular problem(s) you will need to leave space so the problems are in order.
When we collect these notebooks we will only look in the left margin for the problem numbers.
Centered at the top of each page you will write the associated chapter and section number. For example, problems associated
with chapter 3, section 2 would have 3.2 at the top of the respective pages. (See the example at the net site)
Your notebook will be collected May 3rd during your discussion.
Your legible name (first & last), course number (2355) & discussion section number must be written on the outside of the
front cover of your notebook.
No late notebooks will be accepted. Late is the same as losing 10% of your course grade.
If you are repeating the course, you may not turn in your notebook from a previous semester.
We will look at all of your work and decide a notebook grade, based on completeness, neatness, directions followed,
organization, etc. You may ask any discussion leader, or me, any time during the semester to check the format of your notebook.
Notebooks will be returned in computer lab on May 5th . You must claim your notebook by the end of your computer lab
period. Any notebooks not picked up during this time will lose 2 of the possible 10 notebook points.
MyMathLab (MML) Online Homework:
10% (or 12% if you are option A) of your final grade is based on homework problems worked online via MML. I will provide
you with a separate set of instructions for online registration.
Online assignments are usually around 10-12 questions. These problems are chosen as representative of the basic concepts
presented in the sections. These few questions will not adequately prepare you for the exams. Instead, these will help you develop
a basic proficiency in the topics, and give you immediate feedback so you know how well you are doing. More in-depth problems
are in the textbook, and you are encouraged to work odd numbered problems in addition to any assignments given.
Most homework assignments on MML can be revisited as many times as you like. If you miss a question, you should redo that
question until you succeed. You should settle for nothing less than 100% on each online homework assignment. Due dates are
shown in MML and on the course calendar. You will not be able to work an assignment for a better grade after the due date has
passed. There are times that the site is overloaded so do not wait until the last minute to do the online homework. If you
procrastinate and fail to get the assignment done at the last minute you will receive a zero (or whatever score you have recorded)
for that assignment. Your 4 lowest scores will be dropped at the end of the semester. I will give you 5 extra points toward exam 1
if you register for MML by noon, February 1st.
Accommodations for Students with Disabilities
 If you have a physical, learning, or psychological disability and require accommodations, please let me know as soon as
possible. You will need to register with, and provide documentation of your disability to, University Disability Support
Services (UDSS) in SEO, room 330 Knight Hall, 766-6189, TTY: 766-3073.

If you feel that you have what people refer to as math anxiety I would highly suggest that you call or visit the Counseling
Center in room 341, Knight Hall and get some help. The phone number is 766-2187. With math anxiety many people
score very low on math exams. This is something that unless you look into changing may cause you to not pass the course.
OTHER INFO
 During class cell phones are to be turned off (both vibrate & ring) & put away.
You should not to be text messaging during class or utilizing any other features on your phone.

Any student with ear buds in their ears during class will be asked to leave class.
 Make-up quizzes, exams, and labs are allowed only with a “University authorized absence” slip.
Authorized Absences (unireg 713): For participation in a University-sponsored activity or for unusual circumstances, such as
personal hardship, an authorized absence may be issued to the student by the Director of Student Life or the Director’s
authorized representative. If a student has been hospitalized, or if the student has been directed by the Student Health Service
or the student’s private physician to stay at the student’s place of residence because of illness, the Health Service medical staff
or the student's private physician may issue a statement to the student giving the dates of the student's confinement.
 A good calculator is needed for the course. Throughout the course I highly recommend the usage of either a TI-84 or a TI-89.
However, you may also choose to use a nongraphics calculator. Since there is a variety of calculators being used for the course,
you will not be allowed to simply give answers to problems because your calculator has certain formulas built in. The built in
formulas should be used to check the work you have done. I expect you to bring your calculator to every class. For exams or
quizzes you will not be allowed to borrow a calculator from someone else. Don’t put yourself in the position, because you
forget your calculator, of trying to do work by hand. No palm pilots, cell phone calculators or calculators larger than the TI
graphing calculators are allowed.
 I expect you to keep noise to a minimum during lectures. You and the person(s) you are talking with may not care to hear
the lecture but that does not give you the right to deny others the right to learn. If you find that those around you are talking too
much please let me know. I will be as discrete as possible in getting the noise toned down. If I find that the same students
persist, I will either ask them to leave or I will assign them seating.
 Each lecture we will cover approximately a section of the text. You are responsible for all material presented in class. The
large group lecture before each exam will be used for review. Review problems for the exams will also be posted at the net
site.

Cheating of any type, as defined in the University Regulations, will result in a grade of F.
 Attendance in lectures and discussion sections is perhaps your best route to success. Beforehand, try to skim over or read the
material to be covered in lecture. Try working problems before and soon after the lecture while material is fresh.
Open your book, read your notes, and do problems several times a week. Ask lots of questions and clarify any doubts
immediately. Feel free to come to my office at any time. Math Lab, in the basement of Ross Hall, room 29, is also a good
resource for getting help. Take good notes. The main key is attendance and working lots of problems.
Tutoring is also available for this class at the STEP Tutor Center. STEP is open Sunday-Thursday from 6-10pm and is located
in Coe Library. Sessions are drop in (no appointments) and are 30 minutes in length. Students who seek academic help in this
class tend to perform 15-20% better than students who do not. Please visit the STEP Tutor Schedule for days and times:

You must attend the section in which you are registered. You may not attend other sections. You are
welcome to attend any of the listed office hours.
Attendance
If you are not present for the entire Tuesday discussion time you will not be allowed to take the quiz. In other
words, you can’t just show up to take the quiz 15 minutes before class ends. If you attend discussion, I expect
you to be prepared (have your book, calculator, and notebook out and be ready to go). I also expect you to be
respectful of your fellow students. If your discussion leader asks you to leave because you are being
disruptive you will first need to visit with me about the situation before you will be allowed back in the class.
All policies and procedures as outlined on the previous pages apply to your discussion section.
Math 2355 Discussion & Notebook Problems
These are the problems from your book that you will work in your homework notebook.
Your cue for doing each set of homework is when I tell you that I have finished a section.
The calendar lists the sections being covered each Tuesday in small group.
Quizzes will reward an understanding of these concepts.
