Considers the theoretical validity of two approaches to cognitive style. Wholist-Analytic maintains that cognitive processes depend on the interaction of two opposing forces, destructive and constructive. Reflection-Impulsivity characterizes learners according to their reflective or impulsive responses to solution hypotheses. Evaluates these…

Criticizes the use of test-retest correlations, differences between means, and other group effects in studies attempting to evaluate the relative stability of learning styles. Examines the use of the "Learning Style Inventory" and the "Learning Style Questionnaire." Recommends that researchers directly analyze the stability and…

Examines similarities in implementing theories of multiple intelligences, learning styles, and brain-based education in middle schools: (1) theories are learning and learner-centered; (2) teacher is a reflective practitioner and decisionmaker; (3) student is a reflective practitioner; (4) the whole person is educated; (5) the curriculum has…

Develops and validates an instrument for determining student preferences for multiple representations of functions and establishes baseline data for future research. Students showed preferences for representations of functions which varied between contextualized and noncontextualized settings. Students' preferences for the two settings were more…

Reviews constructivist and sociocultural approaches to child development and early education. Outlines a neo-Piagetian systems approach to early learning and development which examines development as the result of coactions between multiple levels of hierarchical individual-environment systems. Discusses a neo-Piagetian curriculum, Rightstart, for…

Describes a science enrichment program for 5- to 8-year- olds that used constructivist theory to create a social learning environment conducive to science learning. Considers the strategic actions and roles the teacher adopted to achieve theoretical objectives. Presents evidence that the children engaged in knowledge generation and critical…

Discussion of the situational dynamism of user-centered relevance estimation focuses on a study that used magnitude estimation to express the relative importance of each document retrieved from an information retrieval system. Topics addressed include relevance estimation as a cognitive schema and the relationship between learning and user…

Explores the prediction of the referential theory, which maintains that the relative complexity of discourse representations plays a key role in determining the perceiver's immediate parsing preferences. Results indicate that semantic/referential principles are applied immediately in an online ambiguity resolution and preempt general world…

Proposes that an important role for connectionist research in language acquisition is analyzing what linguistic information is present in the child's input. Recent connectionist and statistical work analyzing the properties of real language corpora suggest a priori objections against the utility of distributional information are misguided. This…

Argues that the unit operations laboratory provides an ideal setting to help chemical engineering students become better engineering practitioners. Describes a summer program at the Colorado School of Mines that incorporates experience into a unit operations laboratory. (DDR)

Presents an architecture of an intelligent system to support learning that is able to address the issues that arise from constructivist theories of learning in a way that, rather than opposing to the standard intelligent tutoring system architecture, characterizes a broader view in all its components which can be appropriately attuned to address…

Addresses the implementation and evaluation of a constructivist course and extends the argument toward the induction of teachers into critical constructivism through their own action-research projects. Data is taken from a single case study illustrating the changes in the professional life and reflective practice of one teacher in Brazil. (AIM)

Discusses the meaning of a "contextual approach" to teaching physics. Advances a model of contextual physics teaching that can also be applied to other science disciplines. (Contains 54 references.) (Author/WRM)

Explores factors related to preservice teachers' capacity to understand the learning cycle. Finds that understanding of the learning cycle was related to science teaching outcome expectancy, not to personal science teaching efficacy or to attitudes toward science. (Contains 32 references.) (Author/WRM)

The article presents a reusable online support system, in which an open-ended learning environment is created to scaffold complex, real-world problem solving activities. The major learning components of the system are specifically described, and the internal interactions between different components within the system and the external interactions…
