What kinds of homework seem to be most effective?
This is where things get really interesting. Because homework should be about learning, right? To understand what kinds of homework best help kids learn, we really need to talk about memory and the brain.
Let’s start with something called the spacing effect. Say a child has to do a vocabulary worksheet. The next week, it’s a new worksheet with different words and so on. Well, research shows that the brain is better at remembering when we repeat with consistency, not when we study in long, isolated chunks of time. Do a little bit of vocabulary each night, repeating the same words night after night.
Similarly, a professor of psychology at Washington University in St. Louis, Henry “Roddy” Roediger III, recommends that teachers give students plenty of little quizzes, which he says strengthen the brain’s ability to remember. Don’t fret. They can be low-stakes or no-stakes, says Roediger: It’s the steady recall and repetition that matter. He also recommends, as homework, that students try testing themselves instead of simply re-reading the text or class notes.
There’s also something known as interleaving. This is big in the debate over math homework. Many of us — myself included — learned math by focusing on one concept at a time, doing a worksheet to practice that concept, then moving on.
Well, there’s evidence that students learn more when homework requires them to choose among multiple strategies — new and old — when solving problems. In other words, kids learn when they have to draw not just from what they learned in class that day but that week, that month, that year.
One last note: Experts agree that homework should generally be about reinforcing what students learned in class (this is especially true in math). Sometimes it can — and should — be used to introduce new material, but here’s where so many horror stories begin.
Tom Loveless, a former teacher, offers this advice: “I don’t think teachers should ever send brand-new material that puts the parent in the position of a teacher. That’s a disaster. My own personal philosophy was: Homework is best if it’s material that requires more practice but they’ve already received initial instruction.”
Or, in the words of the National PTA: “Homework that cannot be done without help is not good homework.”
