I'm having a little issue with using this data to compare my current students to my 2010-2011 students because the

**classes were so different in terms of incoming ability level.**My students from this year were already so much lower than last year, that I don't know if I can expect to see improvement in comparison to the two years from test to test based on the flipped classroom.

**But, I think I can look at improvement in the GAP that existed between the two classes.**

The picture below shows comparison scores for the End of the First Semester for last year and this year. Both courses were taught identically (no flipping, same materials, resources, tests, etc). Right off the bat, you can see that my students this year have had

**more than twice the failure rate that I had last year (15.2% vs. 32.1%).**I had more F's 1st semester in my three Algebra 1 classes than I think I have had in all my years teaching combined (or at least close to that!) In addition,

**students receiving A's or B's at the First Semester was 9.7% lower this year than last year.**

In addition to the overall semester grade comparison, I also pulled some test scores from the first semester of each year (both non-flipped) to compare the two classes and to see if the "samples" were similar... All of these averages include the FINAL scores students received after being given the opportunity to retake the test. In 2010-2011, the retake score was capped at 75% (school policy). In 2011-2012, I was given permission to allow a full 100% retake of tests.

*(So, the averages in 2010-2011 would have been even higher had students been able to receive a full 100% in the gradebook).*__Chapter 1__2011-2012 were lower by

**-4.47%**

*Chapter 2a (did not have 2010-2011 raw data)*

__Chapter 2b__2011-2012 were lower by

**-9.77%**

__Chapter 3__2011-2012 were lower by

**-10.92%**

__Chapter 4__2011-2012 were lower by

**-8.51%**

*Chapter 5 & 6 tests were not comparable because the content was switched around between 2010-2011 and 2011-2012.*

**On average, my students this year scored 8.42% lower than my students last year on the first semester tests.**

My First "Flipped" Chapter (experimental phase, no WSQ, just watching the video at home and coming to class to practice)

__Chapter 7__2011-2012 were lower by

**-0.83%**

So, with that, I will still be providing the comparison data for each test, since I have it, and we shall see where it goes.

**My current students averaged 3.5% lower than last year. At first glance, that looks bad (25 D's and F's vs. only 9 from last year on Chapter 8a). However, when comparing the two samples of students and their prior achievement, this actually shows improvement by almost 5% from how they had been performing pre-flipped classroom.**
