In “To Really Learn, Quit Studying and Take Tests,” Pam Belluck of the New York Times discusses the results of a recent study which indicates that tests are not only useful to confirm how much we have learned, but are also useful in the learning process itself. She writes:
The research, published online Thursday in the journal Science, found that students who read a passage, then took a test asking them to recall what they had read, retained about 50 percent more of the information a week later than students who used two other methods.
Participants in the study were divided into four groups, each of which used a different study method. Those in the group that scored highest were asked to take a “retrieval practice” test, which involved studying a passage, writing a 10-minute “free-form essay” on what they recalled from the passage, rereading the passage, and taking the test again.
This study confirms two things we have always believed at Stylus. First, it affirms the importance of “writing to learn,” the practice of short, low-stakes writing assignments to cement learning. Second, it reinforces our recommended method of preparing for standardized tests, which involves repeated testing but, more importantly, thorough understanding of what makes an answer right or wrong. It is not enough to merely take and score the practice section; we see much more improvement among those students who carefully review the mistakes they made, predict and confirm why the correct answer is right and their answer wrong, and then retake a similar (or even the same!) section. This practice is particularly beneficial in studying for the SAT because College Board tends to use very similar questions from year to year–variations on a theme.
The Times article is worth reading in full to explore how it might apply to techniques of learning in general.
