Desirable difficulty
A term from cognitive science, associated with Robert Bjork and Elizabeth Bjork, describing a form of practice (such as interleaving, spacing practice over time, or testing yourself before you feel ready) that feels harder and slower in the moment but produces stronger long-term retention and transfer than an easier-feeling alternative.
Defined in 3 GAGE programs, which carry 3 distinct definitions of it. The wording above is taught in Engineering Judgment and Professional Formation.
How each discipline defines it
The same term does different work depending on who is using it. These are the definitions as each program teaches them, unedited.
A term from cognitive science, associated with Robert Bjork and Elizabeth Bjork, describing a form of practice (such as interleaving, spacing practice over time, or testing yourself before you feel ready) that feels harder and slower in the moment but produces stronger long-term retention and transfer than an easier-feeling alternative.
A learning-science principle that effort applied at the right moment strengthens retention and transfer, even though it feels harder in the moment. It is why the program makes you retrieve, build, and decide rather than simply reading you the answer, always with scaffolding available.
The principle that learning is stronger when the practice is effortful, such as facing a question you cannot yet answer. The professor is deliberately hard because a defense rehearsed against easy questions does not survive a real examination.
