Many elementary and junior high school students do not become proficient with common and decimal fractions because they have established few connections between the form they learn in the classroom and understandings they already have. (Author/GC)

The present study investigated the effects of question prompts in scaffolding novice instructional designers solving ill-structured, instructional design problems in a Web-based learning environment. The effects of question prompts were studied under different prompting conditions (Question-Elaboration vs. Question-Guidance), taking into…

The purpose of this study was to characterize the prior conceptions of molecular structure that organic chemistry students expressed as they learned to interpret nuclear magnetic resonance spectra, and to describe the problem-solving strategies that students employ as they determine molecular structure. The two questions that frame this study…

The hypothesis for this study assumed that subjects who received a diagram representing the structural relationships of a story would be more likely to solve a new and analogous problem than subjects who received two analogs without a diagram. The 151 graduate students who acted as subjects were randomly assigned to one of four treatments: one or…

Two hypotheses, the cognitive capacity hypothesis and the selective attention hypothesis, try to account for the facilitation effects of prior knowledge activation. They appear to be mutually exclusive since they predict different recall patterns as a result of prior knowledge activation. This study was designed to determine whether the two…

Ten- to thirteen-year-old children selected either the objectively more effective keyword method or the naturalistic context method for learning vocabulary meanings. Concludes that, even in the absence of explicit performance feedback, children can be induced to reflect on their use of strategies and their outcomes on subsequent cognitive actions.…

This research report describes strategies that can be used to enable students to appropriately use the scientific method to solve problems during labs and activities. The targeted population consists of middle school science students in a growing middle class suburban area. Evidence of their lack of understanding and application of the scientific…

Interviews with 20 engineers revealed that their approach to technological problem-solving bore little resemblance to the model of "problem-solving through technology" in the Alberta elementary science curriculum. Engineers emphasized the importance of context and previous experience in making decisions about each unique situation,…

Four major concepts of cognitive theory (the importance of context, students' need for transferable knowledge, importance of balancing depth and breadth of knowledge, and the role of prior knowledge in problem solving) are examined, and possible implications of each concept for the curriculum and teaching of ambulatory health care are explored.…

Introduces the growing body of research on development of scientific reasoning skills, focusing on reasoning and problem-solving strategies used in experimentation and evidence evaluation. Maintains that current research examines strategy development and use in moderately complex domains to examine conditions under which subjects' theories…

Previous research has cast doubt on children's ability to use specified evidence when making causal inferences, or, indeed, to differentiate between the specified evidence and their own preconceptions, or "prior theories." The present study continues previous work by distinguishing between children's reasoning in conditions where…

Various researchers have associated meaningful problem solving with methods guided directly by a conceptual knowledge base. By contast, a meaningless solving course, or sequence of operations, is essentially independent of the solver's conceptual understanding of the problem under consideration. This paper is the first to document a meaningless,…

The purpose of this paper is to review the relevant evidence concerning the relationship between knowledge and its effect on learning, with an end to answering the questions: (1) How important is knowledge to learning? and (2) How does the relative importance of knowledge change with development? The paper is divided into three main sections:…

VARIOUS WAYS WERE EXPLORED BY WHICH PRIOR OR PREREQUISITE LEARNING AFFECTS THE LEARNING OF HIGHER ORDER (CRITERION) MATERIAL WHICH BUILDS ON PREVIOUS EDUCATIONAL FOUNDATIONS. THE INVESTIGATION WAS CONCERNED WITH THREE INSTRUCTIONAL VARIABLES (PACING, PRACTICE, AND NUMBER OF STAGES IN A LEARNING HIERARCHY) AND THEIR EFFECTS ON LEARNING RETENTION…

Reports the results of a study of 65 United Kingdom primary school children that examined the effect of software type by comparing children's performance on a male stereotyped version of the software with a female stereotyped version. Topics include computer attitudes, computer experience, and software preferences. (Author/LRW)
