This approach, Frölich said, is the "most predictable and consistent way" of comparing students' work to their peers', and it worked well.
At least it did until the end of the fall term at Hopkins, that is.
As the semester ended in December, students in Frölich’s "Intermediate Programming", "Computer Science Fundamentals," and "Introduction to Programming for Scientists and Engineers" classes decided to test the limits of the policy, and collectively planned to boycott the final. Because they all did, a zero was the highest score in each of the three classes, which, by the rules of Frölich’s curve, meant every student received an A.
“The students refused to come into the room and take the exam, so we sat there for a while: me on the inside, they on the outside,” Frölich said. “After about 20-30 minutes I would give up.... Then we all left.” The students waited outside the rooms to make sure that others honored the boycott, and were poised to go in if someone had. No one did, though.
