Season 10, Episode 12

Filling in the gaps with inferences, with Kristen McMaster, Ph.D.

In this episode of Science of Reading: The Podcast, Susan Lambert is joined by Kristen McMaster, Ph.D., Guy Bond Chair in Reading and professor of special education in the Department of Educational Psychology at University of Minnesota. Together, they explore how reading comprehension isn’t just about what’s on the page—it’s also about what’s not there—and share practical insights on how to support students in developing inference skills. Susan and Kristen also discuss the dual processes of activation and integration when making inferences; the distinction between teaching students to process text actively versus teaching students to apply comprehension strategies; and different types of inferences, including causal, bridging, and elaborative.

Quotes

“Inferencing is really central to comprehension. We wouldn't comprehend if we didn't make inferences.”

—Kristen McMaster

“I would just encourage teachers not to underestimate the importance of supporting even the inferences that might seem obvious to us.”

—Kristen McMaster

“Very broadly speaking, comprehension is how we make sense of the world around us. We're constantly taking in information. We see things; we watch things; we hear things; we read things. And as that information comes in, we are constantly integrating it with what we already know.”

—Kristen McMaster

“Good comprehenders are often making very automatic inferences that they don't even realize.”

—Kristen McMaster

“It helps to explicitly teach what an inference is in language that students will understand.”

—Kristen McMaster

“It can be much more helpful to ask questions during text if you want to influence that mental picture that the child is building. If you wait until after they've read the text, they've already built that representation and it may or may not be quite what you were hoping they would build.”

—Kristen McMaster
