This paper describes a theoretical model for examining teaching and learning in primary mathematics classrooms. The model in intended to be both analytical--to provide insights into classroom incidents--and heuristic--to inform planning and practice. This paper reports on the elements of the model, which are based on Vygotskian theory and…

This paper reports the findings of an experiment designed to test extensions of the Technology Acceptance Model (TAM) within the context of using the World Wide Web to gather and analyze financial information. The proposed extensions are three-fold. Based on prior research, cognitive absorption variables are posited as predeterminants of ease of…

This conference presentation describes how students develop the cognitive processes through which they acquire knowledge from their classroom experiences. The data were taken from five studies of individual students' classroom experience and its relationship to the learning of curriculum content in typical science and social studies units in the…

In a longitudinal investigation, a model was developed to assess behavioral, social, and cognitive influences on the academic self-concept of 104 adolescents (57 males, 47 females) who participated in the Fullerton Longitudinal Study between 18 months and 17 years of age. The basic model was Academic Self-Concept = Constant + Behavior + Social +…

The University of Maryland offers a physics course as part of the Maryland Collaborative for Teachers' Preparation (MCTP) project. One of the course aims is to promote the learning of the concept of a function through the learning of physics. Students learn in small groups through problem solving and with the aid of microcomputer-based…

Helping children to bridge the gap between physical materials and symbolic representations is the focus of this article. Examples are drawn from numerical topics, with several hierarchies illustrated. (MNS)

Tested an expectations-based model of the cognitive processes leading to communication apprehension. Found that expectations are a significant predictor of communication apprehension as measured by self-reports. Also important were communicative goals and the interaction of expected outcome and goal importance. (PD)

Discusses how concept maps with two dimensional diagrams which show hierarchical relationships among concepts of a discipline can be used in teaching physics. An example for teaching a course in electromagnetism at the Federal University of Rio Grande do Sul, Brazil is presented. (HM)

Two experiments demonstrated that a priori expectations and context increase the benefit gained from a preview of a word in parafoveal vision. Subjects named visually presented words preceded by a "preview" stimulus with and without constraints. Subjects combine two sources of information so as to derive a benefit. (Author/RD)

Earlier research with the lexical decision task led to the hypothesis that semantic context facilitates the encoding of words related to the context. Six experiments which employed different tasks (e.g., making a lexical decision) and different experimental paradigms (e.g., tachistoscopic exposures with masking stimuli) further investigated this…

When task-related variables are carefully controlled, the referential communication paradigm provides a useful assessment tool for focusing on characteristics of the speaker in a communicative setting. It serves as a useful instructional tool by providing negative listener feedback for inadequate descriptions. (Author)

Decision-making processes were investigated in a laboratory analogue of clinical diagnosis and through computer simulations of decision making. The data indicated that nonprobabilistic theories can provide plausible and complete accounts of decision behavior and can improve quantitative accuracy of predictions that are based on traditional…
