Important new meta-analysis on the testing effect – with some surprises…

From experience to meaning...

There is a new Best Evidence in Brief and one of the studies the newsletter discusses is all about the effect of testing:

Olusola O. Adesope and colleagues conducted a meta-analysis to summarize the learning benefits of taking a practice test versus other forms of non-testing learning conditions, such as re-studying, practice, filler activities, or no presentation of the material.

Results from 272 independent effects from 188 separate experiments demonstrated that the use of practice tests is associated with a moderate, statistically significant weighted mean effect size compared to re-studying (+0.51) and a much larger weighted mean effect size (+ 0.93) when compared to filler or no activities.

In addition, the format, number, and frequency of practice tests make a difference for the learning benefits on a final test. Practice tests with a multiple-choice option have a larger weighted mean effect size (+0.70) than short-answer tests (+0.48). A single practice…
