Final Examination (details to be announced)
Assessment and Grading Criteria
This is an intensive, undergraduate-level course with regular and firm deadlines.
Weekly Homework Assignments: You will be assigned homework each week, except
for the week of the mid-term, Thanksgiving holiday and the final. Details on
the homework can be found under the assignments icon. Homework format will
normally utilize Microsoft Excel workbooks (sheets). Examples will be posted
on the Bb course for you to study. You must submit your module (week) assignments
by the end of each module (week) period to be considered for grading. Solutions
will be posted in Bb following the submission deadline. Normally, this will
be in the following module (week). Homework is worth 310 total points or 31%
of the final grade.
Weekly Discussion Topics: Discussions are, in essence, the equivalent of ‘class
participation’ in an online course. The instructor will begin facilitation
of these class discussions. Each discussion topic will last for one-week. Discussions
start on Mondays and will end on the following Sunday. (You can find out the
start and end times for each discussion topic in the course calendar.)
Please log into the class and participate in the discussion at least four times
during the one-week window. You are expected to participate in all of the discussion
topics presented during the semester.
Please take care in composing your discussion postings; the idea is to have
a conversation with the instructor and other students in the class, much as
you would in a face-to-face class. (The discussion area should not be a series
of unrelated postings.) You are encouraged to share your ideas, ask questions,
and comment/respond appropriately to other students’ comments. The instructor
will evaluate your discussion postings in terms of both quality and quantity
as part of the course grade. The discussion postings are worth 140 points or
14% of the final grade.
During the first two weeks of the course you will have an opportunity to interact
casually with other students in the class to form virtual study groups. Students
in this class often find it is essential to pair up with other students in
the class to discuss module work. However, submitted homework assignments and
exams are expected to by your own work.
Please use the discussion area as your primary way of asking questions regarding
the class. Often other students will have the same questions, so it is a quicker
and more efficient way for you to get your questions answered.
If you need to contact the instructor with a personal problem or question,
you may use the e-mail page of communications. This contact is only visible
to you and the instructor.
Mid-Term Examination: You will have an open-book mid-term examination for this
course. No collaboration is allowed. Please see the course calendar for the
module (week) of this exam. Further details will be announced prior to this
period using our Bb course. The mid-term examination is worth 200 points or
20% of the final grade.
Final Examination: The final examination will also be an open-book examination
and will encompass the whole course. As with the mid-term examination, no collaboration
is allowed. Further details will be announced prior to this period using our
Bb course. The weight of the final examination is 350 points or 35% of the
You may be asked to complete a mid-term and final course evaluation survey
online for this course. These surveys are completely anonymous and provide
useful information to improve this course for next semester’s students.
These surveys will be listed on the calendar and will appear in the quizzes
section of the course. If you have any questions or concerns about the survey,
please ask the instructor.
Academic Integrity: Each student is expected to maintain the highest standards
of honesty and integrity in academic and professional manners. The University
reserves the right to take disciplinary action, up to and including dismissal,
against any student who is found guilty of academic dishonesty or otherwise
fails to meet these standards.
Access to Education: Qualified students with disabilities needing appropriate
academic adjustments should contact the instructor as soon as possible to ensure
your needs are met in a timely manner. For information on assistive technology
available for student use and additional information on services available
through Student Accessibility Services, see http://www.wnmu.edu/Special%20Needs%202/specialneeds.htm.
Audit: A student may register for a course as an auditor, providing permission
of the instructor is obtained. A student has the first four weeks of the semester
to change a course to audit status. No changes in audit status will be processed
after the fourth week of class. Students are charged the normal tuition rate
for auditing a course.
Collaboration: Collaborate work, such as studying or discussing module assignments
and materials with other class members, is highly encouraged with the strict
understanding that any submitted homework and exams will be your work only.
Students are encouraged to collaborate with each other using the Bb e-mail
discussion area tools.
Copyright: All materials in this course fall under copyright laws and should
not be downloaded, distributed, or used by students for any purposes outside
of this course.
Privacy and Bb Tracking Notice: Bb or the course web site automatically records
all students activities, including, your first and last access to the course,
the pages you have accessed, the number of discussion messages you have read
and sent, chat room discussion text, and posted discussion topics. This data
is accessed by the instructor to evaluate class participation and to identify
students having difficulty using Bb features.
Incompletes, Withdrawals, and Drops: I give out incompletes only under extreme
circumstances. If you are running into problems with the course, please contact
me as early as possible so you do not fall behind.
This course falls under all WNMU policies for last day to drop courses, etc.
please see http://www.wnmu.edu/student.htm or the WNMU Course Catalog for information
on WNMU services and policies. Please see the WNMU academic calendar for course
