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
average
for two exams. For the histrograms all scores were rounded to the
nearest whole
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
an exam
average above 90 after two exams.

Progress to Date

Half or more of this exam tested procedures and specific methods, and most students 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.
