Practices that improve long-term retention of learning


Spacing and retrieval involves separating learning over multiple lessons and providing opportunities for students to recall what they have previously learned in different contexts. Science indicates that this helps to commit learning to long-term memory.

Australian Professional Standards for Teachers

Spacing and retrieval practice is related to 'Focus Area 1.2 Understand how students learn' in the Australian Professional Standards for Teachers.


Spacing and retrieval practice has a strong evidence base that meets our highest standards of evidence. For more information about the evidence base, see below:
