In Fall 2011 MATH 1271 Lec 050 (my lecture section), I taught by
"flipping the classroom", a teaching technique in which
      lectures are viewed on video outside of class
while
      skill-training is done in class.

That semester, 132 of my (Lec 050) students took the final
exam. Including all the lecture sections, 1074 students took the final
exam.

----------------------------------------------------------------------

Summary

The first column is a grade range.  The second column is the
percentage of students in Lec 050 whose final exam letter grade is in
that range.  The third column is the percentage of students in all
lecture sections whose final exam letter grade is in that range.

                   Lec 050       All
                    ------      ------
    A- or above     24.24%      17.60%
    B- or above     44.70%      43.39%
    C- or above     90.92%      87.34%
    D  or above     94.71%      91.34%

There seems to be some improvement, possibly, in part, because of the
unusual teaching technique (flipping the classroom, mentioned
above). Of particular note is the increase in students receiving A or
A-, and the decrease in students receiving D or F.

Raw data for Lec 050

The first column is a letter grade on the final exam. The last column
has the percentage of students with that grade.

    A     23/132 = 17.42%
    A-     9/132 =  6.82%
    B+     4/132 =  3.03%
    B     17/132 = 12.88%
    B-     6/132 =  4.55%
    C+    21/132 = 15.91%
    C     34/132 = 25.76%
    C-     6/132 =  4.55%
    D      5/132 =  3.79%
    F      7/132 =  5.30%

total             100.01%

Raw data for all lecture sections

The first column is a letter grade on the final exam. The last column
has the percentage of students with that grade.

    A     144/1074 = 13.41%
    A-     45/1074 =  4.19%
    B+     60/1074 =  5.59%
    B     129/1074 = 12.01%
    B-     88/1074 =  8.19%
    C+    141/1074 = 13.13%
    C     245/1074 = 22.81%
    C-     86/1074 =  8.01%
    D      43/1074 =  4.00%
    F      93/1074 =  8.66%

total               100.00%
