Cheap and implemented badly and without fidelity 🤦‍♀️

But worse in education because of scale - classroom or school of users instead of individual - and and risk. An adult choosing to use AI is different from children being told to or encouraged to *instead* of learning

The most challenging of all this year’s AP Chemistry FRQs was Q6, the Zn and AI Galvanic Cell question, which identified the most advanced students in the course, generally helping to identify which would receive AP 4s and which would receive AP 5s. 5% of students earned all 4 points on it.

The highest performance on this year’s free-response questions was on Q4, the Methanol and Formaldehyde question. 22% of students earned all 4 points on it.

...students who can answer all but one part of the question are generally receiving an AP 4; and students who can answer 1-2 parts of the question are generally receiving AP 3s. Students unable to answer any part of this question correctly are typically receiving AP 1s and 2s.

...so that the measurement value of the question is high, working well to differentiate between students who should receive 5s, 4s, and 3s. Students who can answer every part of this question are typically receiving an AP 5 for their overall work on the exam...

Question 7, the Glycolate question, is psychometrically pristine, the most statistically “perfect” question I’ve yet seen on this year’s exams, which means that each of the 4 points is significantly different in difficulty from every other point...

...so there are certainly exceptions to the positive trend in performance over time, but it’s good to see that in aggregate, performance is improving alongside increased opportunities.

Another rave for the AP Chemistry community: they have pulled off this year’s significant increase in student performance while also expanding this very challenging course to 18,000 more students...

So this is a good unit for further focus as next year’s AP Chemistry students and teachers seek to extend AP Chem’s super impressive, multi-year trend of stronger content and skill mastery.
