This article presents an approach to disciplinary knowledge, and experiential learning necessary for the Early Childhood Education teachers can teach statistics and probability significantly, effective and systematic. First, are specified a set of basic knowledge about the discipline and exposed the contents sequenced by level; secondly, provides guidance on how they learn and how they should be taught the knowledge of statistics and probability in the first ages; and, finally, are some examples of activities implemented in kindergarten classrooms

L’objectiu principal del Projecte Edubosc és apropar el bosc a l’aula per donar a conèixer a l’alumnat d’educació primària d’entre 8 i 10 anys, la gestió forestal sostenible i la seva importància per als nostres boscos i el seu futur. Per tal d’aconseguir aquest objectiu, el Projecte Edubosc proposa dotze activitats de sensibilització forestal que tracten temes com la multifuncionalitat del bosc, la relació del bosc amb l’aigua, els principals productes del bosc, els oficis vinculats al bosc, la prevenció del risc d’incendis i la titularitat dels boscos. Són temes que els llibres de text no tracten. Aquest treball fa una observació sobre com funcionen les activitats a diverses escoles, a partir dels resultats d’enquestes al professorat i als alumnes. Aquests resultats serviran per proposar alternatives i incorporar noves modificacions al projecte

La sisena hora incideix plenament en l’horari escolar. Les combinacions i les solucions que es podien adoptar eren múltiples. A l’article, s'hi fa una radiografia de la situació actual, alhora que s'hi convida a iniciar una reflexió entorn de les possibilitats i les condicions necessàries per dur a terme canvis que afectin els aspectes estructurals bàsics del sistema

En aquest article, s’hi planteja que, en els darrers temps, s’ha vist la necessitat de preparar l’alumnat no només per dominar els continguts matemàtics, sinó especialment per poder-los usar de manera comprensiva en diferents contextos de rellevància social. S’hi argumenta que els processos matemàtics són les eines que ens proporcionen les matemàtiques per aprendre a usar els continguts i s’hi presenta una proposta que pretén orientar sobre com els podem treballar a l’educació primària

Aquest projecte té la intenció d'identificar i analitzar els efectes de la introducció d'Internet a les escoles catalanes (educació primària i secundària). L'objectiu és posar de manifest la manera com s'utilitza la xarxa en aquest àmbit i en quina mesura contribueix a l'aparició, en els centres educatius, d'una nova cultura adaptada a les necessitats de la societat xarxa. Amb aquest propòsit, aquest projecte desplega les seves línies d'anàlisi per a fer atenció al procés d'incorporació d'Internet, principalment, en tres direccions: la pràctica pedagògica, les formes d'organització i gestió dels centres educatius i la seva vinculació amb la comunitat i el territori. Aquesta investigació ha estat desenvolupada pel grup de recerca ENS (Education and Network Society). Amb una perspectiva comparativa, el treball d'aquest grup vol contribuir, sobre la base de dades empíriques, a interpretar la transformació de l'àmbit educatiu no universitari en els paràmetres que estableix, avui dia, la nostra societat.

Some faculty members from different universities around the world have begun to use Wikipedia as a teaching tool in recent years. These experiences show, in most cases, very satisfactory results and a substantial improvement in various basic skills, as well as a positive influence on the students' motivation. Nevertheless and despite the growing importance of e-learning methodologies based on the use of the Internet for higher education, the use of Wikipedia as a teaching resource remains scarce among university faculty.Our investigation tries to identify which are the main factors that determine acceptance or resistance to that use. We approach the decision to use Wikipedia as a teaching tool by analyzing both the individual attributes of faculty members and the characteristics of the environment where they develop their teaching activity. From a specific survey sent to all faculty of the Universitat Oberta de Catalunya (UOC), pioneer and leader in online education in Spain, we have tried to infer the influence of these internal and external elements. The questionnaire was designed to measure different constructs: perceived quality of Wikipedia, teaching practices involving Wikipedia, use experience, perceived usefulness and use of 2.0 tools. Control items were also included for gathering information on gender, age, teaching experience, academic rank, and area of expertise.Our results reveal that academic rank, teaching experience, age or gender, are not decisive factors in explaining the educational use of Wikipedia. Instead, the decision to use it is closely linked to the perception of Wikipedia's quality, the use of other collaborative learning tools, an active attitude towards web 2.0 applications, and connections with the professional non-academic world. Situational context is also very important, since the use is higher when faculty members have got reference models in their close environment and when they perceive it is positively valued by their colleagues. As far as these attitudes, practices and cultural norms diverge in different scientific disciplines, we have also detected clear differences in the use of Wikipedia among areas of academic expertise. As a consequence, a greater application of Wikipedia both as a teaching resource and as a driver for teaching innovation would require much more active institutional policies and some changes in the dominant academic culture among faculty members.

The disintegration of recovered paper is the first operation in the preparation of recycled pulp. It is known that the defibering process follows a first order kinetics from which it is possible to obtain the disintegration kinetic constant (KD) by means of different ways. The disintegration constant can be obtained from the Somerville index results (%lsv and from the dissipated energy per volume unit (Ss). The %slv is related to the quantity of non-defibrated paper, as a measure of the non-disintegrated fiber residual (percentage of flakes), which is expressed in disintegration time units. In this work, disintegration kinetics from recycled coated paper has been evaluated, working at 20 revise rotor speed and for different fiber consistency (6, 8, 10, 12 and 14%). The results showed that the values of experimental disintegration kinetic constant, Ko, through the analysis of Somerville index, as function of time. Increased, the disintegration time was drastically reduced. The calculation of the disintegration kinetic constant (modelled Ko), extracted from the Rayleigh’s dissipation function, showed a good correlation with the experimental values using the evolution of the Somerville index or with the dissipated energy
