make it stick

In their forthcoming book, Make It Stick: The Science of Successful Learning, researchers Henry Roediger III and Mark McDaniel (along with writer Peter Brown) liken expertise to a “brain app” that makes reading and other kinds of intellectual activity proceed more efficiently and effectively. In the minds of experts, the authors explain, “a complex set of interrelated ideas” has “fused into a meaningful whole.”

The mental “chunking” that an expert — someone deeply familiar with the subject she’s reading about — can do gives her a decided speed and comprehension advantage over someone who is new to the material, for whom every fact and idea encountered in the text is a separate piece of information yet to be absorbed and connected. People reading within their domain of expertise have lots of related vocabulary and background knowledge, both of which allow them to steam along at full speed while novices stop, start, and re-read, struggling with unfamiliar words and concepts.

Deep knowledge of what we’re reading about propels the reading process in other ways as well. As we read, we’re constantly building and updating a mental model of what’s going on in the text, elaborating what we’ve read already and anticipating what will come next. A reader who is an expert in the subject he’s reading about will make more detailed and accurate predictions of what upcoming sentences and paragraphs will contain, allowing him to read quickly while filling in his already well-drawn mental model. A novice reader, by contrast, faces surprises at every turn in the text; her construction of a mental model is much more effortful and slow, since she’s building it from the ground up.

Lastly, the expert reader is able to vary the pace of her reading: skimming parts that she knows about already, or parts that she can tell are less important, then slowing down for passages that are new or that (she can judge from experience) are especially important. The novice, on the other hand, tends to read at just a single speed: if he tries to accelerate that speed, by skimming or by using an app like Spritz, it’s likely his comprehension will slide. What’s worse, he probably won’t even realize it: lacking deep familiarity with the subject, he won’t know what he doesn’t know, and may confuse main ideas with supporting details or miss important points altogether.

Expertise has its own limits, of course. Becoming an expert is a long, slow process, and each of us can develop true expertise in only a few areas…
