Case comparisons, where students compare two or more tasks, have been reported to support students' multivariate reasoning.…

The authors describe cross-decades changes in the achievement attitudes and behaviors of average U. S. undergraduates that parallel the declines in meaningful learning reported by Arum and colleagues.
