## The Secret Gripes of Professor Klein: An AP-IB Drama

David Klein, a mathematics professor at California State University at Northridge, says he was pleased to review Advanced Placement and International Baccalaureate math courses for the Thomas B. Fordham Institute. He respects institute President Chester E. “Checker” Finn Jr., a longtime leader in the movement to improve U.S. schools. Among the views Klein shares with Finn is that overuse of calculators can interfere with students’ mastery of analytical skills.

But their collaboration on Fordham’s analysis of AP and IB did not turn out the way either of them hoped.

On June 4, Klein submitted his report on two courses, AP Calculus AB and IB Mathematics SL. Klein’s analysis of AP and IB math was more negative and his grades lower than what the experts on AP and IB English, history and biology courses submitted to Fordham. He would have given the AP math course a C-plus and the IB math course a C-minus. The other reviewers thought none of the courses they looked at deserved anything less than a B-minus.

Still, Klein says, he got no indication from the Fordham staff of any problems until the edited version of his material came back to him for review on Sept. 28, a week before the deadline for completing the report. Many of what he considered his strongest points, he discovered, had been deleted. He had Fordham remove his name as a co-author of the report, “Advanced Placement and International Baccalaureate: Do They Deserve Gold Star Status?” which was released Nov. 14.

After agreeing to the name removal, Finn told Klein in an e-mail: “I imagine we’ll also reduce your overemphasis on calculator use and probably change the grades (upward). Thanks, tho, for your help.” Klein’s grade of C-plus for AP was not changed, but his grade of C-minus for IB got a big jump to a B-minus, meaning the report was saying that IB math was better than AP math, the opposite of what Klein had said.Related:
