Together ChemEd 2023 (University of Guelph) and 2025 (Colorado) committees are organizing the “Best of ChemEd” symposium with the help of AACT. Engaging sessions each day along with social events will highlight what ChemEd is all about – a community of chemistry teachers sharing ideas, resources, and successes.

In the Best of ChemEd session, the focus will be on the results of the 2021 AP Chemistry Exam. The Chief Reader and Chief Reader Designate will present the results of the 2021 AP Chemistry Exam. They will describe current practices in exam development and scoring, with an emphasis on specific content areas and skills that were tested on the free-response section. The presenters will share statistical data on student performance and highlight common misconceptions on the most challenging questions. Participants will learn how the 2021 AP Chemistry Exam was constructed and scored, with the goal of incorporating these assessment practices into their own classrooms. There will be plenty of time to ask questions!
