The role of a subject's conceptual knowledge in the procedural task of searching a text for information was studied for 51 college undergraduates in 2 experiments involving knowledge of anatomy. Students with more anatomical information were able to search a text more quickly. Educational implications are discussed. (SLD)

Explored influence of changes in kindergartners' knowledge about a protagonist on earlier constructed memories of the story. Found that children's story recall was affected by their prior impressions. Following the second knowledge manipulation, children revised story reports consistent with newly acquired impressions, suggesting that they had…

In this study, 5- and 6-year-olds were read a story and asked to recall its details. Two independent factors-prestory knowledge and poststory suggestions-were crossed to examine the effects on children's story recall. The results indicated that prestory social knowledge about the story protagonist as well as academic knowledge relating to the…

Two experiments on preschoolers' understanding of the effects of exposure on knowing-that and knowing-how were conducted with 3-, 4-, and 5-year-old children (N=388) in 2 locations: a small midwestern city in the United States and a suburban area of Hong Kong, China. By using both English- and Chinese-speaking samples, the authors examined…

Prior knowledge is often argued to be an important determinant in hypermedia learning, and may be thought of as including two important elements: domain expertise and system expertise. However, there has been a lack of research considering these issues together. In an attempt to address this shortcoming, this paper presents a study that examines…

Using concept maps, a Kellert-type (S. R. Kellert, 1985) inventory, and self-report behavioral items, this cross-age study assessed public knowledge, attitudes, and behaviors toward bottlenose dolphins. Results suggest that this important megafaunal species is poorly understood by the public at large, and that negative "utilitarian" attitudes and…

Background knowledge plays an important role in one?s ability to learn. We learn new knowledge by relating it to our prior knowledge, which in turn provides concrete understanding (Piaget, 1969). Rosenblatt (1996) explained, "The reader brings to the work personality traits, memories of past events, present needs and preoccupations, a…

In most teacher education courses, instructional strategies are merely listed and explained. Students rarely have the opportunity to see these strategies in use until they become student teachers. What better way to teach secondary instructional strategies to pre-service teachers than by modeling these strategies using teacher education content?…

This qualitative case study considers factors such as difficulty of understanding mathematics and poor mathematics practicing strategy under academic factors and lack of family support under social factors as those that contribute to the failure. Many students entering community college have deficiencies in mathematics background and are required…

A number of terms have been used to describe knowledge needed for teaching, one of which is subject knowledge. How knowledge for teaching is conceptualized in teacher education prioritizes some knowledge bases over other knowledge bases. Further, knowledge prioritized by student teachers is influenced by socialization prior to and during an…

Research suggests that the World Wide Web (WWW) represents the intersection of at least two domains: content and technology. This investigation was designed to examine the relationship between prior knowledge and WWW browsing outcomes (i.e., navigation behavior and knowledge gain) within the context of a genetics Web site. Students randomly…

This study sought to determine the effects of prior knowledge on the achievement of undergraduates in an economics course at the Open University of the Netherlands (OuN). A total of 49 law and 39 economics students were given 4 instruments to test prior knowledge of economics, presented with a learning unit from the course "Economics and…

Three experiments involving 350 undergraduates addressed whether implicit learning is sensitive to a subject's entire range of learning or whether explicit knowledge is an important factor in the more complex learning of an artificial grammar. Results suggest that implicit learning occurs only at the simplest level of complexity. (SLD)

Two experiments examined how 5- and 10-year-olds revised their category representations when exposed to exemplars that were congruent or incongruent with existing knowledge. Findings indicated that judgments about feature co-occurrent within the learned category were influenced by both stereotypical beliefs and exemplar observation. Stereotypical…

Three studies evaluated a method for developing prior-knowledge structures that prepares students to learn from a text or lecture. Findings indicate that there is a place for lectures and readings in the classroom if students have sufficiently differentiated domain knowledge to use the expository materials in a generative manner.
