Hi all, I guess I'll weigh in -- Although I am retired, I am the first doctoral student with Chris Bauer at UNH in Chemical Education, so I am reading a lot about these issues, aside from a large amount on Advanced Placement Chemistry, Physics, and Calculus I had done previously. The College Board has very strict guidelines on structuring an AP Chemistry course. Teachers and administrators violate these at their peril. Some first-year programs are successful, some are not, and students subsequently benefit or suffer. The course is predicated on a previous rigorous exposure to chemistry. Perhaps a well-taught, lab-oriented good Physical Science course in 9th grade would suffice. Then adequate screening for students with the requisite math facility would also be particularly important. When I pushed a second-year course through at Exeter High School I "sold" it to the school board as "Advanced Chemistry," where students could take the AP exam and I would offer extra tutoring throughout the year and before the exam. Since the schools in New Hampshire do not pay the AP fee, the board liked this choice. I also read them research literature on the value of authentic student research (as opposed to "inquiry-learning"), and my curriculum was: âfirst-quarter review of all first-year fundamentals, especially stoichiometry in all of its forms; âsecond-and third-quarter we moved into the topics either weakly or not broached in the first-year course; then âfourth quarter was student-research based. Each student explored various chemical systems I presented them with, and they each found individual directions to go in. Then it was lab every day until the end of school, with periodic student presentations of the work they were doing, and I mainly ran around as a go-fer and supervisor. This turned out to be a very successful course. I welcome more discussion. Best, Cary Kilner
