South Carolina Rep. RJ May (R), who accused drag queens and transgender people of harming children, pleaded guilty last Friday to distributing child sex abuse material, including images of adults abusing 7-year-olds, after initially denying it. He was honored as the 2023 Legislator of the Year.

There are only a few weeks left to submit public comment on the USDOE’s guidance on AI in education, which proposes to saturate K-12 with AI in teaching and learning despite a lack of research into its effectiveness.

A U.S. House resolution has been introduced that would call for the immediate release of the Epstein files.
It has 35 Democratic co-sponsors. Not a single Republican.

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.

By far the most challenging unit for AP Chemistry students was Acids and Bases (Unit 8); 7% of students earned every point possible for this unit, and 6% of students, generally those who are receiving 1s, were unable to answer any question about this unit correctly.

Setting aside Atomic Structure and Properties (Unit 1), which a massive 34% of AP Chemistry students aced by answering every such question right, students demonstrated strongest mastery of Thermochemistry (Unit 6); 18% earned every point possible for that unit.

Equating data, which looks at each group’s performance on re-used MCQs, also confirms that this year’s group, on average, was stronger than prior years’ groups, demonstrating stronger chemistry content knowledge and skills, so scores increased.
