The effects of relevant concreteness on learning and transfer were investigated. Sixth grade students learned artificial instantiations of a simple mathematical concept. Some students were presented with instantiations that communicated concreteness relevant to the to-be-learned concept, while others learned generic instantiations involving abstract symbols. Results suggest that relevant concre...

This study demonstrates that an integrated operator can benefit from cost savings, customer retention and prevention of revenue erosion by FMC migration strategy with introduction of advanced service packages. This development is driven by increasing importance of mobile network capabilities and services, as well as the lessening gap between fixed and mobile systems, in terms of technological m...

We evoke some poetical aspects of a new kind of logical truth (an inner quantum truth) embodying both physical and mathematical concepts, which can be viewed at the same time as a constructive mathematical object, as well as a pure platonic idea.

And while I have sought to shew the naturalist how a few mathematical concepts and dynamical principles may help and guide him, I have tried to shew the mathematician a field for his labour—a field which few have entered and no man explored. Here may be found homely problems, such as often tax the highest skill of the mathematician, and reward his ingenuity all the more for their trivial associ...

A guide for those who wish to understand and to work with the hydro-geochemical equilibrium code CHESS together with introductory aspects of thermodynamic principles and surface com-plexation chemistry. The CHESS model was initially written at the Ecole des Mines de Paris within the framework of the R&D program on Management and Storage of Radioactive Waste

The five papers that comprise this special issue entitled ‘‘The conceptual change approach to mathematics learning and teaching,’’ attempt to demonstrate that the conceptual change approach can be a fruitful component of a theory of mathematical learning and instruction. Some of them focus on issues of learning i.e., on presenting evidence that the conceptual change approach provides a powerful...
