S8 E9: Knowledge building can’t wait, with HyeJin Hwang

Science of Reading: The Podcast

Dr. HyeJin Hwang is an assistant professor and literacy researcher whose research interests revolve around reading comprehension and content learning in K–12 settings, particularly for multilingual students. In this week’s episode of the podcast, HyeJin Hwang talks with Susan Lambert about background knowledge (what it is, how it’s built, and more), the importance of broad knowledge, the connections between knowledge and vocabulary, and unit planning rather than lesson planning. English wasn’t Dr. Hwang’s own first language, and her research on supporting multi-language learners is informed by her own experiences learning English and later teaching English as a second language. Whether you’re just starting to establish a solid foundation on knowledge building or you’re looking to explore the topic from new angles, this episode is the one to listen to.

Quotes:
“Knowledge building cannot wait… Start from the beginning of schooling, from early grades. Multilingual students and monolingual students, they both need support developing knowledge and literacy skills.” —HyeJin Hwang

“In knowledge building, we usually like to go for cultivating in-depth knowledge. That means interconnected ideas need to be told throughout multiple lessons, multiple classes, rather than planning individual separate lessons.” —HyeJin Hwang
“When readers have good broad knowledge, prior knowledge, then it is more likely the readers can recall text information ideas, and they can make better inferences about missing ideas in text.” —HyeJin Hwang
