Welcome to the
Eco251 Web Page
This is a web page in progress. The
page contains links to the course syllabus, course outline with homework assignments,
computer problems, and annotated outline. It will contain old exams and problem
solutions after they are discussed in class. For future use bookmark this page.
My hard drive is regularly checked for
viruses. If you get a virus report, please give me the document number and I
will reboot it. Some virus problems have been reported
in one of the computer rooms. These seem to be in the computer, not in the
documents. If this happens to you, report it to the help desk and try another
room.
My standing offer: If you submit a good exam problem to me, you might just
find it on the exam. The better thought out it is, the more likely it is to go
on the exam with minimal changes. However, since there are 2 Statistics exams,
the numbers are likely to be changed. A number of students have submitted
questions in the past and, I believe, gotten better grades because of it.
My new standing offer: Work to improve
the course, if it is used, will be rewarded by adding extra credit points to
grades on graded homework. This includes, but is not limited to: 1) The first
person to notice an error on any posted document except, maybe, exams; 2) help
to improve course graphics and 3) valuable ideas for new documents or problems.
Notices:
You should always be sure that
you have a copy of the current outline pages to bring to class. You should know
how to access Blackboard.
http://courses.wcupa.edu/rbove/entering_blackboard_for_the_first_time.doc
In addition to the prerequisites, you are expected to be
able to express yourself in writing. All e-mails to the instructor at rbove@wcupa.edu should
be in grammatically correct but not terribly formal English with the
spelling checked.
From the Tutoring Center:
How
to sign up for a tutor
- Come to 105
- You may sign up for up to three different courses.
Make sure you give us the course name, course number, and your section
number.
- If our tutors are booked, you will be placed on a
waiting list. We will contact you as soon as a space becomes
available.
- Remember, tutors are assigned on a first come,
first serve basis. If you anticipate a problem in a given subject, sign up
early -- crisis tutoring does not work.
- The LARC cannot schedule more than one tutoring
session per class, per week. Exceptions are reviewed on a case by case
basis.
- If you have a learning disability or require
individualized tutoring, let us know right away. We will try to
accommodate your needs as much as possible.
May Notices
May 8 –
Grades will not be complete until Tuesday of next week and I will not be in the
office. If you wish to know your exam and term grade, you may e-mail me. Final
exams will be available for checking during the first term of summer school.
May 2 –
Note that I will allow you to start the final exam early. I do not expect to be
on campus regularly for several weeks after Wednesday,
If you are getting or negotiating a
‘No grade’ and intend to make it up rather than retaking the course, it must be
finished before I leave WCU in early August. The solution to last year’s final
is at 251y0741. But you could
probably benefit from studying second, third and final exams in OLD EXAMS.

Jan 9 – For class schedule, see below. On the first day of
class, I will hand out the following Documents: SYLLABUS
and the
documents from the OUTLINE – and lecture summaries that are listed in 251descrCover1.
There will be a revised academic dishonesty statement that must be signed and
returned to me.
Jan 8 – I am posting my schedule
for the spring below. Actual office hours during each week will be posted on
the next page.
Every year a significant minority of Students taking
Economics 251 and 252 receive a grade of C- or lower. Almost all of these
students are required by the Business program to receive a C or better in the
course. When this requirement was imposed, I asked the faculty if I should now
be giving C’s to the people who would have earned a C- before the requirement
was imposed and was told that I should not. Almost all the people who received
a grade of C- or lower for the course received a grade of D+ or lower on the
final exam, this was a score of 18 out of a nominal 75 on the exam.
Every year students who received grades of C- or
lower ask me if there is some way they can make up the grade. Unfortunately
this is impractical and defeats the purpose of a grading system. Almost all of
these people will tell me that they worked hard and attended all of my classes.
Good intentions, however, are no substitute for being able to show me that they
learned something. I, therefore, must say no to requests to do something to
make up the grade. It just doesn’t seem reasonable to believe that people who
learned relatively little during the term are going to suddenly understand
statistics or that I could offer this opportunity to everyone who did not get a
C. I, honestly, have no idea how anyone can make up this grade in the few weeks
before the start of the next term.
