Reading comprehension is multidimensional and complex. The persistent challenges children, adolescents, and even adults face with reading comprehension call for concerted efforts to develop assessments that help identify sources of difficulties and to design instructional approaches to prevent or ameliorate these difficulties. Doing so requires…

College students with either high or low prior domain knowledge (PK) read a text chapter presented in short pages on a computer monitor. Half of the participants read with headings present and half with headings absent. The computer recorded time spent reading and rereading each short page. Learning was assessed through a structured recall task.…

Investigates effects of prior knowledge on learning from high- and low-coherence history texts. Examines participants' comprehension in two experiments. Finds high-knowledge readers performed better on open-ended questions after reading low-coherence text. Indicates that low-coherence text requires more inference processes--these inferences are…

Examines the effects of 2 levels of prior knowledge and 2 types of text structure on the recall and question performance of 90 fifth graders who were average readers. Finds that prior knowledge has a greater effect on question performance than on recall performance and that it only enhances the recall of one section of the text information. (MG)

Assesses prior knowledge and involvement in high school readers whose backgrounds would seem to match the possible interpretations of an ambiguous text. Finds that (1) prior knowledge resulting from actual group membership exerted only a modest effect on interpretation; (2) readers' level of involvement predicted text interpretation reliably; and…

A study investigated the role of prior knowledge in ambiguous text interpretation by directly measuring readers' knowledge of, and level of involvement with, three distinct topical domains that could be assigned during reading of an ambiguous passage. Subjects, 52 athletes of average or above average reading ability competing in one of three…

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…

Investigates how structural variables influence readers' construction of meaning. Finds that textual variables operate differently depending on the extent of the readers' background knowledge and linguistic competence. Shows that variable such as exposure to reading materials (in both first and second languages), background knowledge, and…

Investigates whether advance organizers facilitate the acquisition of subordinate information from text. Examines the influences of reader's background knowledge, advance organizers, relative importance of idea units, and idea units' position within a text structure on the recall of textual information. (SR)

A study investigated the relationships among prior topic knowledge, information in elementary science text, and the construction of visual representation of key text ideas. Eight preservice elementary teachers were first interviewed on two topics in science ("how plants get their food" and "air and weather"); then they read…

A study investigated the effects of text processing orientations and reader-generated versus text-based comprehension aids on readers' comprehension of expository text. The processing orientations included memory-oriented processing, organization-oriented processing, understanding-oriented processing, and a read and study control. Subjects, 136…

To determine whether mastery of one reading comprehension task is a prerequisite to mastery of two or more reading comprehension tasks, a study examined the prerequisite relations existing in the item responses elicited from a sample of sixth grade students who took the Iowa Tests of Basic Skills, Form G, Level 12 reading comprehension test. Test…

Examines proficient and less proficient high school comprehenders' use of strategies as they read three passages with different top-level structures: collection, causation, and comparison. Finds that both groups of readers use similar strategies. Finds that proficient comprehenders use more previous knowledge on the collection passage and more…

A review was conducted of the research related to the ability of elementary school children to carry out search tasks with informational text. The review was organized within a framework of components of the search process: goal formation, text selection, information extraction and integration, and evaluation. The research reviewed suggests that…

Examines reader and text variables related to conceptual change learning from science textbooks. Shows it is difficult to change readers' prior knowledge by reading texts that are inconsistent with that knowledge, but refutation text was shown to impact students' prior knowledge when that knowledge contained naive scientific conceptions. Addresses…
