The objective of the present study was to replicate a qualitative prediction, that prior relevance information is predicted to be a powerful performance variable, in the context of other variations as well as to assess new quantitative predictions for these conditions based on the theoretical work.

Results showed that, contrary to predictions based on standard models of the logical time concept, long and short conditions were easier for children to solve than the traditional four- versus seven-second condition. Children were able to solve problems that are logically impossible to solve on the basis of nontemporal information. (Author/RH)

This paper introduces issues related to the role of intuitive knowledge in physics learning. Phenomenological primitives, which form the base level for intuitive explanations in the research, are discussed. Three primary questions are the focus of this paper: (1) What role, if any, does intuitive knowledge play in physics problem solving? (2) How…

Experiments were conducted to determine the influence upon task difficulty of these factors: age; percentage of redundancy between relevant and irrelevant cues; saliency of reinforcement, discriminability of relevant nonpreferred dimension, and learning set pretraining to reject preferred irrelevant dimensions.

Presents responses to the Fair Share Problem. (Author/YDS)

Explains "Mathematical Mind Journeys," a lesson format that promotes computational fluency through variable practice that relies on mathematical memory rather than rote memorization. (Author/NB)

Even after repeated instruction, first year college chemistry students are often unable to apply stoichiometry knowledge to equilibrium and acid-base chemistry problems. The dynamic and interactive capabilities of online technology may facilitate stoichiometry instruction that promotes more meaningful learning. This study compares a…

The professional expertise of educational leaders has been defined through the lens of problem-solving processes. Problem-based learning has therefore become an increasingly popular instructional approach in principal preparatory programs. As such, this study represents an initial attempt to explore learning from success (i.e., success-based…

This study examined average-, high- and top-performing US fourth graders' rational number problem solving and their understanding of rational number representations. In phase one, all students completed a written test designed to tap their skills for multiplication, division and rational number word-problem solving. In phase two, a subset of…

The perspective of situated learning offers a theoretical framework for understanding the dialectical relations between the social and the individual dimensions of classroom microculture. The purpose of this article is to show how sociomathematical norms constructed during whole-class discussions provide a reference for the elaboration of…

This article contributes to the study of decision-making processes both at a farm systems level and at the level of agricultural research in partnership with commercial farms. It also highlights the way in which adoption and adaptation of innovation occurs in a socially rich context with information, group formation and connectivity converging to…

Most college algebra courses are offered in the spirit of preparing the students to move on toward calculus. In reality, only a vanishingly small fraction of the million students a year who take these courses ever get to calculus. This article builds a strong case for the need to change the focus in college algebra to one that better meets the…

Article expands on one aspect of conceptual conflict, contradiction, in order to illustrate in greater detail how it might be exploited in educational practice. (Author)
