Knowledge plays an inarguably critical role in reading comprehension. When considering the science of reading, it is important to engage with varying theoretical frameworks and empirical research that inform our collective understanding regarding the intersection of knowledge and literacy in K-12 classrooms. Therefore, the purpose of this article…

This study investigated how well seventh-grade students (n = 1,434) evaluated the credibility of online information in science. The analysis examined the extent to which evaluation appeared to share aspects of other elements of online research and comprehension, including locating, synthesizing, and communicating. This study also investigated the…

Previous research has identified various factors that contribute to readers' comprehension of expository texts, including strategy expertise, language proficiency, prior knowledge, and more recently, readers' beliefs about knowledge. This study addresses the need to understand the relative contributions of these predictors to readers'…

The study compared the effects of a refutation text on comprehension and learning outcomes to those of a standard expository text. Undergraduate students with varying amounts of accurate and inaccurate prior knowledge read and recalled a refutation or an expository text about energy. Comprehension measures included the amount of text information…

Is there an achievement gap for online reading ability based on income inequality that is separate from the achievement gap in traditional, offline reading? This possibility was examined between students in two pseudonymous school districts: West Town (economically advantaged) and East Town (economically challenged; N = 256). Performance-based…

Examines the ability of children to evaluate their comprehension of text using lexical, external, and internal consistency standards. Finds that children more often use lexical and external consistency than internal consistency and that the results of verbal report measures are inconsistent with performance measures. (RS)

Discusses the results of a study that examined the relationship between comprehension ability and prior knowledge in children's recall of structurally equivalent text. (AEA)

Examines the influence of prior knowledge on expert readers' strategies to identify and state a text's main idea. Identifies three methods of constructing the main idea: automatic construction; draft-and-revision; and topic/comment. Concludes that expert readers' construction of the main idea is often a mediated, strategic task. (RS)

Supports the function of analogy in activating specific background knowledge and generally related knowledge in reading unfamiliar text, a view consistent with emerging schema theoretic notions. (AEA)

Reviews research on the effects of world knowledge and text structure variables on reading comprehension. Concludes that text structure variables exert influence only when the subject matter is moderately unfamiliar and are redundant in reading familiar or very difficult material. Suggests knowledge and structure variables should be manipulated…

An approach to assessing context dependence was applied to data from the Nelson-Denny Reading Test. The results suggest that scores on the difficult passages are inflated because the examinees can answer the questions without having to comprehend the passage. (MKM)

Examines previous studies of the effects of prediction activities, prior knowledge, and text type upon reading comprehension. Finds the three elements unimportant to ordinary reading. Observes that many schema theory concepts arose from analysis of difficult reading. Suggests that the schema theory variables may arise only in atypical reading…

Examines the effect of prior knowledge and difficult vocabulary on students' recall of a passage from a social studies text. Concludes that vocabulary difficulty may affect microprocessing (development of coherent text base) while prior knowledge may affect macroprocessing (summarizing), and that these effects function independently, not…

Describes an experiment that explored the relationships between text structure, prior knowledge, and reader's purpose on the processing of text and memory for text information. Results demonstrated that the strategies used to read text are flexible. (HOD)

A prereading strategy designed to predict events and provide practice in answering questions requiring inferences between text and prior knowledge were used with elementary school students. The performance of experimental groups surpassed that of the control groups on some measures while results were mixed on other measures. (MKM)
