Interleaving is not a well-known term among those who teach, and it’s not a moniker whose meaning can be surmised, but it’s a well-researched study strategy with positive effects on learning. Interleaving involves incorporating material from multiple class presentations, assigned readings, or problems in a single study session. It’s related to distributed practice—studying more often for shorter intervals (i.e., not cramming). But it is not the same thing. Typically, when students study and when teachers review, they go over what was most recently covered, or they deal with one kind of problem at a time.
