A study investigated the hypothesis that mental imagery facilitates access to prior knowledge and therefore enhances the ability to infer and make text-relevant predictions. The subjects, 29 first grade and 29 third grade students, were randomly assigned to either an experimental group where they were instructed to make pictures in their head to…

Using computer controlled text presentation that permitted the measurement of reading time for individual sentences, a study tested two hypotheses concerning how schemata guide reading comprehension. The focusing hypothesis suggested that the schemata activated by the reader's perspective might identify relevant information to which additional…

Presented is an analysis of a concept teaching technique that was developed according to a theoretical perspective which emphasizes the importance of a student's existing knowledge in influencing that person's subsequent learning. Significant differences between an experimental group which was exposed to this instructional strategy, and the…

Discusses what is meant by meaningful learning, the conditions necessary for meaningful learning to occur, the importance of vocabulary instruction to comprehension, and how to insure that vocabulary instruction is meaningful. (HOD)

Describes two studies showing that young readers may have trouble with comprehension when text contradicts their own prior knowledge. (FL)

Researchers studied the effect of interpolating extraneous information on students' ability to process cognitive information concerning their prior performances on the McCloy block test. The extraneous information was given in the interval between their last test and their next attempt to perform it. Results are discussed. (Author/PP)

Describes an instructional procedure based on the findings of schema research and illustrating the truth that the more students know about a subject, the better they can comprehend what they read about that subject. (FL)

Compared Introductory Physical Science (IPS) and Modified approaches to teaching physics concepts. Found that students' preinstruction ideas of matter and density were organized in commonsense theories that constrained understanding of density. Both curricula promoted quantitative understanding of mass, volume, and density, but the Modified…

The purpose of this study was to determine if factors to predict success in college biology (i.e., prior knowledge of biology or reasoning ability) depend on the instructional method employed (i.e., expository or inquiry). Reasoning ability was found to account for a significant amount of variance in final examination scores, regardless of…

Examines the role of social interaction as a facilitator of learning in general and conceptual change in particular. Three conditions are proposed as necessary for social interaction to facilitate knowledge construction--horizontal information, comparable domain knowledge, and availability of cognitive tools. Suggests that these conditions assure…

Discusses how second-language reading research is focusing increasingly on the cognitive processes involved in reading--the interaction of lower-level, bottom-up processes such as vocabulary acquisition with high-level, top-down processes such as activating prior knowledge. This knowledge is combined with current research on learning with…

This paper describes the conceptualizations, or mental models, of the nature of the bonding and structure of metals of a group of U.K. college students. It is suggested that these mental models may be understood in terms of the students' prior learning about covalent and ionic bonding, and the prevalence of a common alternative conceptual…

Adaptive motor actions require prior knowledge of instrumental contingencies. With practice, these actions can become highly automatic in nature. However, the molecular and anatomical substrates mediating these related forms of learning are not understood. In the present study, we used in situ hybridization to measure the mRNA levels of two…

The technology, symbol systems, and processing capabilities of a medium interact to provide unique opportunities for information access. This exploratory study examines the way that learners process videotaped materials on a familiar or unfamiliar topic as informed by text-based research. A variation of the think-aloud method of assessing…

The effects of mobilizing prior knowledge on information processing were studied. Two hypotheses, the cognitive set-point hypothesis and the selective attention hypothesis, try to account for the facilitation effects of prior knowledge activation. These hypotheses predict different recall patterns as a result of mobilizing prior knowledge. In…
