Foundations of Mathematics Spring 2017
Comments on the first exam
Scores for the first exam have been posted on blackboard. Exams
will be returned in class on Tuesday, 2/28/17. It is important
that you come to class to pick up your exam because you are assigned to
work with a group to write up a set of solutions that will be due Tuesday, 3/7. Exam solutions
are a required component for the course portfolio. Specific
When you get your
exam, please double check that I have added up the points correctly and
also that the score on your paper is the same as the one posted on
blackboard. I try hard not to make errors totaling or recording
scores. But if an error has been made, I will want to correct it
as soon as possible.
The exam scores are shown in the histogram below.
The histogram shows that the class as a whole did pretty well.
Over 1/2 of the scores are at 90 or above, and all but a few of the
scores are at 80 or above. At this point nearly everyone is
satisfactory grade, and most are on track for a final grade
of B or better.
To interpret your exam score, you should
understand my grading system. I work with a numerical scale from
50 to 100. When I grade the answer to a problem, I first make a
judgement as if I were assigning a letter grade to that particular
item. An A answer
should receive between 90% and 100% of the points; a B between
80% and 90%, and so on. So if you receive half the points on an
item, that means I consider the response to that item as a fail. Anything less than 70%
on an item indicates your response was judged to be unsatisfactory.
