3. Don’t just reread books and notes
As a teen, Cynthia Nebel studied by reading her textbooks, worksheets and notebooks. “Over and over and over again,” recalls this psychologist at Vanderbilt University in Nashville, Tenn. Now, she adds, “we know that’s one of the most common bad study skills that students have.”
In one 2009 study, some college students read a text twice. Others read a text just once. Both groups took a test right after the reading. Test results differed little between these groups, Aimee Callender and Mark McDaniel found. She is now at Wheaton College in Illinois. He works at Washington University in St. Louis, Mo.
Too often, when students reread material, it’s superficial, says McDaniel, who also co-wrote the 2014 book, Make It Stick: The Science of Successful Learning. Rereading is like looking at the answer to a puzzle, rather than doing it yourself, he says. It looks like it makes sense. But until you try it yourself, you don’t really know if you understand it.
One of McDaniel’s coauthors of Make it Stick is Henry Roediger. He, too, works at Washington University. In one 2010 study, Roediger and two other colleagues compared test results of students who reread material to two other groups. One group wrote questions about the material. The other group answered questions from someone else. Those who answered the questions did best. Those who just reread the material did worst.
