"Flipped Data" (PART 3 FOR Algebra 1 - Chapter 9)

To see all data collected, please see the "FLIP Data" tab up top

In 2010-2011, Chapter 9 was a "mandatory remediation and retake" test for all of my students.  As you can see, 2010-2011 students had a 60% class average with 58% of the students receiving D's or F's.  Once these students went through an extra week of class time, before and after school required tutoring, and a new version of the test, the class average was 72.7% with only 37% of the students receiving D's or F's.

For my flipped classroom this year, there was no extra mandatory remediation or support outside of the normal class time.   My students scored amazingly better compared to last year's pre-remediation students, and just about right on par with the post-remediation students, which shows a great impact of the flipped classroom!

As compared to the pre-remediation 2010-2011 students, my flipped classroom students this year scored

9.83% higher in class average
25% more students received A's or B's
20.6% fewer students received D's or F's!

How awesome!!!!!

As compared to the post-remediation 2010-2011 students, my flipped classroom students this year scored

2.64% lower in class average
exact same % students received A's or B's
.75% more students received D's or F's

2012 Algebra 1 Data notes:

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.
