Elementary Differential Equations, 2nd Edition, by Kohler and Johnson

Prerequisites
• Math 1206 or equivalent in placement, Math 1114 or Math 2114

Web Information
• Scholar: The course contract, syllabus, and other materials essential to this course can
be found on our class Scholar site.
• Course Website: http://www.math.vt.edu/courses/math2214/

Grading
Your final grade in the course is based on the following work:

Homework 10%
Quizzes 15%
Tests 54%
Final 21%

A 90% will guarantee an A-, 80% a B-, 70% a C-, and 60% a D-.

Grading Appeals
Specific grading disputes (points totaled incorrectly, partial credit appeals, missing assignments on
Scholar, etc) should be brought to my attention within 1 week of return of the assignment. Appeals
outside of this timeframe will not be considered.

Quizzes
You will have thirteen online quizzes due each Wednesday starting 1/28/15. The quiz will cover
material from the last week of class (up to the Monday before the quiz) and two of the questions will
be on material from the previous two quizzes, respectively. I will drop the lowest quiz grade. You may
find the practice quizzes at:
http://www.emporium.vt.edu/emporium/enterpractice.app.html
You may take the graded quizzes at:
http://www.emporium.vt.edu/emporium/entertesting.html

Midterm Tests
You will have 3 Midterm Tests. Your lowest test grade will be replaced by your grade on the
final, if it is an improvement.

Final Exam
There will be a multiple choice common time final exam scheduled to take place on May 8, 7:00 –
9:00pm (rooms will be assigned later). The final exam counts 21% of the class grade. The final exam is
a required class meeting that will not be rescheduled for discretionary reasons, including conflicts
with work schedules and with classes and exams at other colleges.

Homework
There will be an assignment due in class roughly each week. You are encouraged to work together
on homework assignments, however your final write-up must be done independently. No late
assignments will be accepted. To account for this, your lowest assignment score will be dropped.

Classroom Courtesy
You and your classmates are entitled to learn in an atmosphere of mutual respect, and freedom from
distractions and disturbances. The following guidelines are in effect for this class:

• Students are expected to arrive on time and stay until class is dismissed.
• If you know ahead of time that you will be late or must leave early, please let me know in

advance, sit as near the exit as possible, and enter or leave quietly
• Talking to classmates during class, aside from group assignments, is disruptive to those

around you and will not be tolerated.
• Laptops used as a tablet PC are permitted provided they are used in the flat, tablet

position. Open laptops are not allowed.
• Cell phones must be silent or turned off. That goes for anything else electronic that makes

noise.
Honor System
The Virginia Tech Honor System will be strictly enforced. Tests (including the final exam) and quizzes
must be solely the individual’s work. Homework, however, may be completed in collaboration with
others but should be written up on an individual basis. It is your responsibility to seek clarification if
there is any question about how the Honor Code applies to a given assignment.

Disability Statement
If you need adaptations or accommodations because of a documented disability, if you have
emergency medical information to share with me, or if you need special arrangements in case the
building must be evacuated, please make an appointment with me as soon as possible.

Caution
If you are not on the class roll that comes out after the last “add” date, you are not in the class. It is
your responsibility to make sure you are attending the proper section. For no foreseeable reason
(computer and/or registrar personnel mistakes included) will you be allowed to stay in the wrong
section. Your work will not be graded. Simply attending a section will NOT entitle you to be placed
on its roll.
