Posting summary charts for the 2014-2015 AP Calculus AB cohort in a similar fashion to prior years. The major difference in the post will be the level of commentary pertaining to the data. My passion for blogging, and teaching, took a major hit about 6-8 weeks into the semester. I am still recovering from the experience. I will likely blog about it when I feel ready. Now is not that time.
The following table shows that the most recent cohort scored similarly to the 2013 cohort on the final exam, which is good news. Even better, the size of the cohort is nearly 25% larger. This gives me confidence for the cohort heading into the second semester.
The following figure compares this cohort’s distribution of scores on the final exam to the three prior cohorts. While there are slightly less scoring at the highest end, the lowest end has diminished as well.
Comparing end of course scores for the 2014-2015 cohort with last year’s cohort reveals a slight dip for scores above 70% with a near doubling of the percentage of scores between 60-69%.
Comparing my ratings scale where end of course outcomes are classified as far below basic, below basic, basic, proficient, and advanced, it appears that student performance may not be as strong with this cohort, or it took longer thereby negatively impacting cumulative scores, hence ratings.
Finally, comparing final grades for this cohort with prior year cohorts shows a comparable distribution to last year’s cohort, which is the most important given the similarity in pedagogy and policies for the two cohorts.
While scores shifted slightly for this recent cohort, their overall performance still places them in a strong position for second semester, as well as the AP Exam. I look forward to working with these students this coming semester.
