Where to Get Help
326 Walker Hall
I am always happy to help you in office hours. An open door
means that I am on the floor somewhere, so come look for me.
Check the main page often for homework and for access to
the other class web pages.
is the easiest way to ask a math question outside of class and office hours.
You are responsible for reading all posted files and messages from me.
I prefer that you use office hours since it is easier to discuss
material in person, but if you can not make them, then ASULearn
is a great alternative.
I usually check it every day including the
Lab in Walker. Students answer questions.
Elementary Linear Algebra
by Larson and Edwards. 5th Edition.
loose-leaf notebook and hole puncher
to organize handouts, notes and your work
printouts of your Maple work
access to a web-browser and to Maple
on the file server and/or at your own computer -- mac or pc is fine
(on-campus access is sufficient
as long as you have the time to work on campus while the labs are open)
An introduction to linear algebra,
via selections of Chapters 1-7 of the textbook and Maple modules
Learn about the historical and modern applications of linear algebra
An exposure to proofs
Develop mathematical reasoning, problem solving, algebraic,
visualization, and writing skills
Math 2240 has been designated as a
computer designated course. We will be using Maple
to satisfy the designator.
You are expected to contribute to discussions in a meaningful way and
actively engage the material in class and lab.
You must be prepared for each class and check the main web page regularly
for hw. Attendance is required.
This means that when we are doing a calculation, you must also do this,
and you are expected to take notes since the book does not contain everything
you need to know.
These kinds of baseline activities will result in a participation grade of
Other activities can increase or decrease this grade.
Utilizing office hours and ASULearn,
asking and answering thought provoking questions, coming up with creative
ways of thinking about the material, and explaining
the material to others are some examples of positive participation that will
increase your grade. On the other hand, performing
activities that detract from the professional classroom environment
or distract Dr. Sarah (who is very easily distracted) will
result in a lowered participation grade.
Many activities and class discussions are designed to be completed during
class. Thus, attendance is required at ALL classes, and will form a portion
of your grade. In addition,
missing more than the equivalent of 2.5 weeks during the
semester (5 classes) will result in an automatic F in the
course. Save your absences for emergencies. If the university is open and
you miss a class, then that counts as an absence. If you must be late to a
class, or must leave early, then do still attend.
Projects and Problem Sets 35%
Work will not be accepted without explanation and
must also be turned in on or before the due date because solutions will
If there is some reason you must miss a class,
then obtain the assignment from the web pages.
The lowest project will be dropped - save this for
emergencies. If all of your work is turned in on time and you have
received at least a grade of 75% for all work, then you will receive +1
added on to your final average.
Major topic exams 35%
No make-up exams will be given. May occur during the last week of class.
You should view exams primarily as a learning experience.
This means that exams are not only an opportunity for you to demonstrate
your mastery of the material, but are also an opportunity for you
to be challenged with new material in order for you to make
new connections. To encourage exams as a learning experience
some extra points will be granted for test revisions.
Final project poster presentations 15% No make-ups allowed.
* Work may occur during the last week of classes.
Accommodations in the determination of your final grade will be made
for extenuating circumstances that are documented to prevent you from
completing work early/on time. In addition,
Appalachian State University is committed to making reasonable
accommodations for individuals with documented qualifying disabilities
in accordance with the Americans with Disabilities Act of 1990, and
Section 504 of the Rehabilitation Act of 1973. Those seeking
accommodations based on a substantially limiting disability must contact
and register with
The Office of
Disability Services (ODS) at
or 828-262-3056. Once registration is
complete, individuals will meet with ODS staff to discuss eligibility
and appropriate accommodations.
When writing up work, be sure to give acknowledgment where it is due. Submitting someone else's work as your own (PLAGIARISM) is a serious violation of the
University's Academic Integrity Code.
We adhere to the code in this course.
Material is covered very quickly.
Plan to spend at least 1-2 hours outside of class for each
credit hour in class, (on average).
You are responsible for all material covered and all announcements
and assignments made at each class, whether
you are present or not. You are also responsible for announcements
made on the web pages, so check them often.
Asking questions, and explaining things to others, in or out of class,
is one of the best ways to improve your understanding of the material.
This course is to be an environment in which everyone
feels comfortable asking questions,
making mistakes, offering good guesses and ideas, and is respectful to
You should explore each problem
and write out your
thinking in a way that can be shared with others.
Focus on your own ideas.
Turn in projects or prepare to present problems
even if it they are not complete, even if only to say, "I do not
understand such and such" or "I am stuck here."
Be as specific as possible. Conjecture.
When writing up work, be sure to give acknowledgment where it is due.
Submitting someone else's work as your own (PLAGIARISM) is a serious
violation of the University's Academic Integrity Code.
In this course, you will be challenged with problems that you have never
seen before. I do not expect you to be able to solve all the issues
immediately. Instead, I want to see what you can do on your own.
Out in the real world, this is important, since no matter what job
you have, you will be expected to seek out information and answers
to new topics you have not seen before.
This may feel uncomfortable and frustrating. I understand this
and want to help you through the process.
It helps to remember that
there are no mathematical dead-ends!
Each time we get stuck, it teaches us
something about the problem we are working on, and leads us to a
deeper understanding of the mathematics.
In the real world though, you are not expected to face your work alone.
You will be allowed to talk to other people
may even be expected to work with other people.
In this class, you are also not expected to face your work alone.
I encourage you to talk to me often in class, office hours,
and the bulletin board.
I am always happy to help you, and will
try to give you hints and direction to help you understand the material.
At times though, to encourage the exploration process,
I may direct you to rethink a problem
and to come back to discuss it with me again afterwards. This occurs
when I believe that the struggle to understand is imperative for your
deep understanding of the material.
