Riflettere in gruppo come pratica emancipativa

2021

Un percorso di consapevolezza legato ad una pratica auto-osservativa e autoriflessiva all’interno del proprio contesto di lavoro è di grande importanza per la formazione personale e per un apprendimento organizzativo; implica infatti, la comprensione dei processi cognitivi individuali, organizzativi o istituzionali in cui si è immersi e costituisce uno spazio indispensabile perchè avvengano degli “apprendimenti di secondo livello”. Ciò comporta lavorare sul piano dei significati, non solo con quelli espliciti propri e altrui, ma anche con le premesse che danno origine a prassi comuni e condivise . Fondamentale in questo senso è la dimensione di gruppo perché consente di adottare una logica …

Cette 6eédition, totalement réactualisée, d’un manuel devenu « la » référence sur le monde de l’école, des élèves et des enseignants, explore le domaine de manière systématique et objective, et sous des aspects divers : place de l’école dans la société (politiques scolaires, inégalités de carrière, enjeux de la réussite scolaire, évolution des analyses théoriques), mais aussi acteurs et pratiques (profession enseignante, programmes, pratiques éducatives des familles, métiers d’élève).L’ouvrage propose ainsi de nombreux éléments sur les effets des politiques éducatives, la construction et les effets de ségrégation scolaire, ou encore les changements introduits par le renouvellement des ensei…

Evaluation in French Higher Education: history, policy and debates

2013

En ligne sur : http://www.scuolademocratica.it/wp-content/uploads/2013/05/Oss-Int-1_2013-Chevaillier.pdf; Working Paper de "Scuola Democratica, learning for democracy", 2013/05; The French Higher Education System is presently undergoing one of the deepest transformations of its history. In the last few years, several major pieces of legislation, partly unconnected, have triggered a process of change that will alter the structure of the system, the relations among its various components as well as their internal organisation. Parallel to these structural changes, the higher education and research system has been building up a comprehensive evaluation apparatus.After a short account of the pr…

Utility of the Mantel-Haenszel Procedure for Detecting Differential Item Functioning in Small Samples

2004

Sample-size restrictions limit the contingency table approaches based on asymptotic distributions, such as the Mantel-Haenszel (MH) procedure, for detecting differential item functioning (DIF) in many practical applications. Within this framework, the present study investigated the power and Type I error performance of empirical and inferential criteria for DIF detection in small samples. Sample sizes (50/50, 100/50, 200/50, and 100/100 for the reference and focal groups, respectively), ability distributions (equal and unequal), and amount of DIF (moderate and high) were manipulated. The results show the advantages of employing theMHchi-square statistic using high levels of significance (•…

The social benefits of restoring water quality in the context of the Water Framework Directive: A comparison of willingness to pay and willingness to…

2009

The Water Framework Directive (WFD) is by far the most important piece of water legislation in Europe for the coming decades. Its main aim is to achieve "good ecological status" for all water resources by 2015. The economic valuation of the non-market benefits derived from improving water quality is an important input in assisting the design and implementation of efficient and effective water management policies. In this study, the contingent valuation method has been applied with a double purpose. On the one hand, we have estimated the value of a hypothetical improvement in water quality of a river asking individuals about their willingness to pay, and on the other hand, the issue of exemp…

Meeting the environmental challenge of port growth: A critical appraisal of the contingent valuation method and an application to Valencia Port, Spain

2012

In order to support effective policy-making, this research is aimed to emphasise the need of measuring the negative impact - or external costs - resulting from port growth. Considering the non-market nature of these external costs, a critical appraisal of the Contingent Valuation method is made paying special attention to the problem of hypothetical bias and the suitability of a willingness to accept (WTA) scenario for damage assessment. Finally, the results of a case study, conducted in Valencia (Spain), are presented with the intention of paving the way for future research in this specific context of port growth and negative externalities. In particular, results indicate that the average …

To Pay or Not to Pay: Competing Theories to Explain Individuals’ Willingness to Pay for Public Environmental Goods

2010

Dieser Beitrag ist mit Zustimmung des Rechteinhabers aufgrund einer (DFG geförderten) Allianz- bzw. Nationallizenz frei zugänglich. This publication is with permission of the rights owner freely accessible due to an Alliance licence and a national licence (funded by the DFG, German Research Foundation) respectively. Several theories have been proposed in an attempt to explain individuals’ willingness to pay (WTP) for public environmental goods. While most studies only take into account a single theory, this article discusses competing theories. These include, in addition to a basic economic model, the theory of public goods, Ajzen’s theory of planned behavior, and Schwartz’s norm-activation…

Estimating willingness to pay for desalinated seawater: the case of Djerba Island, Tunisia

2017

AbstractWater scarcity can be a growth-limiting factor. Non-conventional water resources, such as desalinated water, represent an alternative means of guaranteeing access to water while reducing water stress. In this study, a contingent valuation survey carried out in Djerba Island, Tunisia, allows the joint modelling of two decisions: societal support for the construction of a desalination plant and households’ willingness to pay for desalinated water. To the best of the authors’ knowledge, no study to date has addressed this relationship. We find that although a clear majority of households are in favour of using desalinated water, far fewer are willing to pay for it. The article conclude…
