Ultra short post. Posting results for my fifth cohort of AP Calculus AB students on the fall final exam. The (nearly) identical final has been used all five years; one question was changed in year two or three.
Scores improved significantly on the final for this cohort. I believe there are a variety of factors contributing to the improvement:
- I taught 80% of these students last year in honors precalculus,
- I created practice quizzes (with fully worked solutions) and tests to aid them in preparing for all assessments to include the final, and
- I lessened use of the “flipped classroom” providing more direct instruction before students engaged with their homework.
Net-net, I am pleased with the results for this cohort.
Updated post with following data addressing a reader’s comment re: relative distribution of former v. new students in 2015 results.
I suspect that if I ran a t-test on the former v. new data it would yield a statistically significant improvement in many of these descriptive statistics.
