Calculus 1 -- Fall 2017
Results from second exam
The class turned in another strong performance on this
exam. The scores from exam 2 have been posted at our Blackboard site.
When you get your paper back, please check that the score posted on
Blackboard is correct. You should also add the points up on the
exam to be sure I did not make an error. Keep in mind that in the
total score, values of 1/3 and 2/3 were both rounded to 1/2.
I have prepared a handout with comments I recorded as I was
doing the grading. That will be handed back with the exams.
Below are histograms both for this exam and for each student's
for two exams. For the histrograms all scores were rounded to the
number, and scores ending in .5 were rounded up. The first
histogram shows, for example, that two students earned the class high
score of 95 (after rounding), and
there were 6
scores (roughly 40% of the class) at or above above 92 on the second
exam. The second histogram shows that 8 students (out of 15) have
average above 90 after two exams.
Progress to Date
At this point, all but 3 of the students are on track to earn at
least a B- in this course. The exam averages are so high
that some might be concerned that grade inflation is occurring.
However, based on experience, it is likely that scores will
go down somewhat in the final third of the course, due to
difficulty of the material and general student
fatique. So, even if you are completely satisfied with
where you stand right now, don't get complacent! To
keep your performance at the same level, you need to keep working
as hard or harder as in the first 2/3 of the semester.
Half or more of this exam tested procedures and specific methods, and
demonstrated a good command of this material. Unfortunately,
there were also a few students who appear not to have mastered major
portions of the material we covered. In some cases, I suspect
this reflects insufficient dedication -- that is, not doing
enough homework and studying. Any students in this category
should take note: even if you are on track for a satisfactory grade
today, a poor performance on the final could
result in a grade of D or F. At the same time, any student who is
making a dedicated effort with class attendance, homework, and
studying, but who still is not doing well on exams, is invited to come
and discuss the situation with me in my office.
I am again asking students to work in groups and prepare a set
of exam solutions. The solutions will be due on Tuesday
11/14. The projects should follow the same guidelines as before.
