The study presented here concerns the results obtained from the development and the experimentation of a didactic exergame realized by the University of Salerno. The aim of this exergame, called “Gioco delle Forme”, is to evaluate, measure and “train”, by means of a playful activity with a high degree of body involvement, the skills of visual and motor integration, skills that for scientific li...

The aim of this research is to understand the way in which students struggle with the distinction between dimensionality and “directionality” and if this type of potential confusion could be a factor affecting students’ tendency towards improper linear reasoning in the context of the relations between length and area of geometrical figures. 131 9th grade students were confronted with a multiple...

Automated theorem provers, applications, and libraries of problems are often developed separately. In some cases, joint efforts of many of researchers led to standards such as DIMACS (for propositional logic) [6] and SMT (for satisfiability modulo theory) [1] and libraries of problems such as SAT-lib (for propositional logic) [11], TPTP (for predicate logic) [18], SMT-lib (for satisfiability mo...

This paper provides a comparative gestural account of nasal vowels in Southern French (Marseille, Toulouse; France) and in Northern French (Liège, Tournai; Belgium). Timing measurements based on acoustic data confirm a different temporal organisation of the gestures between the two regiolects. We also report on statistical comparisons between phonetic events (such as duration of the SF ‘nasal a...

The most suitable paradigms and tools for investigating the structure of granular packings are reviewed and discussed in the light of some recent empirical results. I examine the ‘typical’ local configurations, their relative occurrences, their correlations, their organization and the resulting overall hierarchical structure. The analysis of very large samples of monosized spheres packed in a d...

During recent years a number of papers by Carrel and others concerning the rate of healing of wounds have been published. Du Noiy has also applied some mathematical treatment to these observations and constructed some graduation formulae. In the application of these formulae, however, I think that the meaning of the figures has been in some measure obscured and that a different treatment reveal...

A three-dimensional numerical computation of magnetohydrodynamic dynamo behavior is described. The dynamo is mechanically forced with a driving term of the Taylor-Green type. The magnetic field development is followed from negligibly small levels to saturated values that occur at magnetic energies comparable to the kinetic energies. Although there is locally a nonzero helicity density, there is...

In elicitation tasks, people are asked to make estimates under conditions of uncertainty but elicitors then interpret these estimates as if the estimator were certain of them. An analysis of people’s patterns of responding during the elicitation of uncertainty, indicates that there are markers of confidence incorporated into these estimates that can be used to predict the person’s true level of...

The process of convening arbitrary real numbers bito a floating poini format is formalized as a mapping of the reals into a specified subset of real numbers. The structure of this subset, the set of n significant digit base ß floating point numbers, is analyzed and properties of conversion mapp.ngs are determined. For a restricted conversion mapping of the n significant digit base ^numbers to t...
