The testing effect (also known as retrieval practice, active recall, practice testing, or test-enhanced learning)[1][2][3] suggests long-term memory is increased when part of the learning period is devoted to retrieving information from memory.[4] It is different from the more general practice effect, defined in the APA Dictionary of Psychology as "any change or improvement that results from practice or repetition of task items or activities."[5]
Cognitive psychologists are working with educators to look at how to take advantage of tests—not as an assessment tool, but as a teaching tool [6] since testing prior knowledge is more beneficial for learning when compared to only reading or passively studying material (even more so when the test is more challenging for memory).[7]
