In the seven years since the original CPM Research Report was posted, the new research has continued to validate the efficacy of the three pillars of CPM pedagogy:
Students learn ideas more deeply when they discuss ideas with classmates.
Students learn ideas more usefully for other arenas when they learn by attacking problems—ideally from the real world.
Students learn ideas more permanently when they are required to engage and re-engage with the ideas for months or even years.
These three principles (termed respectively as collaborative learning, problem-based learning and mixed, spaced practice) have driven the development of the CPM textbooks from the beginning, and each year these principles are validated by more research to prove their effectiveness.
