Elementary Math Models -- Fall 2017

Results for Exam 1

This webpage will give an overview of how the class performed as a
whole on the exam. Further down, there are also some comments
about how items were graded. Please read them carefully.

If you are dissatisfied
with your performance on the exam, please make an appointment to see
me. Bring your exam and portfolio to the meeting, and I may
be able to suggest ways to make
your preparations more effective for the remaining exams. And I am open
to any suggestions about how I can make the course more supportive of
your
efforts.

You can find your individual score posted on Blackboard. When you
get the exam back in class, double check that the score on your paper
is the same as what is recorded on blackboard. Also, add up your
points for the entire exam and double check that I have the right total
for your paper. I am very careful totalling and recording scores,
but mistakes CAN occur.

**Comments On Grading Scale.**

For the first page there were two types of questions. For 2 and 5, where you know that there is one correct answer, you receive 50% credit for any incorrect answer and 100% for the correct answer. For the remaining questions each of the options is essentially a true/false item, and you lost 3/4 of a point for any item that is wrong, either because you marked it true when it was false, or the opposite. The grading may not make it clear what the correct answer(s) are. That is intentional. Students should try to figure that out as part of the group project.

Finally, note that I do not use a rigid predefined grading scale. At the end of the course I want to be able to adjust the cutoffs up or down so that students with nearly equal scores receive the same letter grade, as far as possible. Because of the way partial credit is assigned, the cutoffs will be close to the traditional 90/80/70/60 marks. Usually the breakdown is something close to 93 - 100 A, 90-92 A-, 88-89 B+, 83-87 B, 80-82 B-, 78-79 C+, 73-77 C, 70-72C-, 60-69 D, < 60 F.
