Self-Testing Boosts Info Retention

Self-Testing Boosts Info Retention
Alexis Mattera

Did you spend your Sunday distraught over Jay Cutler and the Bears or horrified by the atrocity that was Mean Girls 2? I know I’m not completely alone here but, being the diligent students you are, many of you were probably holed up in the library preparing for your first exam of the spring semester and quizzing yourself on key pieces of information. Good thing, as a new study says self-testing while studying is the best way to retain facts and figures.

The study, "Retrieval Practice Produces More Learning than Elaborative Studying with Concept Mapping," was conducted by Purdue’s Jeffrey Karpicke and Janell R. Blunt and found that since learning is fundamentally about retrieving, practicing retrieval while studying is crucial to learning. The study focused on two groups of students (200 altogether) who were asked to read several paragraphs about differing scientific topics but one group was instructed to use the information to create a concept map and the other was told to put away their articles and spend 10 minutes writing what they recalled. When the students were tested on the same material one week later, the group that practiced retrieval retained 50 percent more information than those who engaged in concept mapping. Strangely, researchers also found that despite learning less, the students who engaged in concept mapping were more confident that they would remember the material than those who practiced retrieval while studying.

What’s your preferred study method? Is it producing the results you want? Will you employ the retrieval method given this study’s findings?
