School composition effects in Spain

Drawing on PISA data of 2006, this study examines the impact of socio-economic school composition on science test score achievement for Spanish students in compulsory secondary schools. We define school composition in terms of the average parental human capital of students in the same school. These contextual peer effects are estimated using a semi-parametric methodology, which enables the spillovers to affect all the parameters of the educational production function. We also deal with the potential problem of self-selection of student into schools, using an artificial sorting that we argue to be independent from unobserved student’s abilities. The results indicate that the association between socio-economic school composition and test score results is clearly positive and significantly higher when computed with the semi-parametric approach. However, we find that the endogenous sorting of students into schools plays a fundamental role, given that the spillovers are significantly reduced when this selection process is ruled out from our measure of school composition effects. Specifically, the estimations suggest that the contextual peer effects are moderately positive only in those schools where the socio-economic composition is considerably elevated. In addition, we find some evidence of asymmetry of how the external effects and the sorting process actually operate, which seem affect in a different way males and females as well as high and low performance students.

Technology, business models and network structure in the airline industry

Network airlines have been increasingly focusing their operations on hub airports through the exploitation of connecting traffic, allowing them to take advantage of economies of traffic density, which are unequivocal in the airline industry. Less attention has been devoted to airlines? decisions on point-to-point thin routes, which could be served using different aircraft technologies and different business models. This paper examines, both theoretically and empirically, the impact on airlines ?networks of the two major innovations in the airline industry in the last two decades: the regional jet technology and the low-cost business model. We show that, under certain circumstances, direct services on point-to-point thin routes can be viable and thus airlines may be interested in deviating passengers out of the hub.

Is it redistribution or centralization? On the determinants of government investment in infrastructure

The dilemma efficiency versus equity, together with political partisan interests, has received increasing attention to explain the territorial allocation of investments. However, centralization intended to introduce or reinforce hierarchization in the political system has not been object as of now of empirical analysis. Our main contribution to the literature is providing evidence that meta-political objectives related to the ordering of political power and administration influence regional investment. In this way, we find evidence that network mode’s (roads and railways) investment programs are influenced by the centralization strategy of investing near to the political capital, while investment effort in no-network modes (airports and ports) appears to be positively related to distance. Since investment in surface transportation infrastructures is much higher than that in airports and ports, and taken into account that regions surrounding the political capital are poorer than the average, we suggest that centralization rather than redistribution has been the driver for the concentration of public investment on these regions.

What are the causes of educational inequalities and of their evolution over time in Europe? Evidence from PISA

This paper provides evidence on the sources of differences in inequalities in educational scores in European Union member states, by decomposing them into their determining factors. Using PISA data from the 2000 and 2006 waves, the paper shows that inequalities emerge in all countries and in both period, but decreased in Germany, whilst they increased in France and Italy. Decomposition shows that educational inequalities do not only reflect background related inequality, but especially schools’ characteristics. The findings allow policy makers to target areas that may make a contribution in reducing educational inequalities.

Why do educated mothers matter? A model of parental help

The paper investigates the role of mothers in affecting childrens' performance at school. It develops a theoretical model in which household is treated as an individual, whose utility depends on the performance at school of the student and on consumption. The model focuses on the possibilities through which mother’s help may affect pupil's performance in terms of time devoted to supervision and spillover effects. Empirical evidence, using Italian PISA 2006, shows that highly educated mothers have a positive impact on students' score only when they are highly qualified in the job market.

La participació social de grups vulnerables davant l’exclusió educativa : contribucions des de la recerca europea

En aquesta memòria es detallen totes aquelles activitats d’investigació, formatives, i de difusió de les recerques realitzades en els darrers 6 mesos, gràcies a la concesió de la beca de Formació de Personal Investigador (FI), modalitat B, de la Generalitat de Catalunya. La proposta presentada a la convocatòria i que va ser aprovada, “La participació social de grups vulnerables davant l’exclusió educativa. Contribucions des de la recerca europea” , ha tingut com principal objectiu d’estudi: analitzar la relació entre la inclusió/exclusió educativa i la inclusió/exclusió en l’àmbit de la participació social i política en els grups vulnerables. En el compliment d’aquest objectiu he participat en dos projectes de recerca: "INCLUD-ED, Strategies for inclusion and social cohesion in Europe from education", finançat pel VI Programa Marc de la Comissió Europea (2006-2011), i on està adscrita la beca, i en el projecte del Plan Nacional I+D+I "TRANSMIGRA. Análisis de los procesos de transnacionalidad económica y política marroquí, ecuatoriana y rumana. La migración como factor de desarrollo en los países de origen y acogida". La participació en aquests dos projectes ha representat una gran experiència formativa per desenvolupar els dos treballs de recerca per l’obtenció del Diploma d’Estudis avançats (DEA). En un dels treballs del DEA, he estudiat des d’una perspectiva històrica la discriminació de la dona, tant social com educativa i de gènere, a la Barcelona dels anys 30 i com els ateneus llibertaris van ser un espai per superar aquesta exclusió. L’altre treball del DEA s’ha centrat en aquelles pràctiques inclusives que es desenvolupen a les escoles entorn l’aprenentatge d’història i en concret en l’ús de la història oral com a pràctica docent També en aquesta memòria s’expliquen les activitats formatives, les participacions a congressos, així com les publicacions resultants a partir de les recerques realitzades.

L'ús dels clítics pronominals del català i la seva adquisició per parlants de romanès i de tagal

El nostre estudi ha analitzat els mecanismes de transferència de la L1 en dos grups de parlants, un que té el romanès i l’altre el tagal com a llengües mare, en el procés d’aprenentatge del català com a L2. En concret ens hem centrat en l’estudi de l’ús dels clítics pronominals, una de les parts de la gramàtica catalana més apassionant per les seves idiosincràsies i la seva diversitat formal. L’ús d’aquest tipus de pronoms és un aspecte que resulta complicat d’adquirir per parlants de llengües en què no existeixen o on l’ús que en fan és diferent. En el nostre estudi, ens hem basat inicialment en la descripció de les característiques fonamentals dels clítics pronominals del català, del romanès i del tagal, a partir de bibliografia especialitzada i més general, i, en el cas del català, fent servir també la pròpia competència. Després d’aquest apartat més descriptiu, hem utilitzat un corpus d’entrevistes fetes en català a dos grups de parlants, el primer amb aprenents de català que tenen el romanès com a L1 i el segon amb aprenents de català que tenen el tagal com a L1, per analitzar quantitativament i qualitativament l’ús dels clítics pronominals. Un altre grup d’entrevistes, aquesta vegada a persones autòctones (català L1), ens ha servit com a grup de control. El nostre estudi dóna suport a la hipòtesi que atorga una importància especial a la transferència de la L1 en l’adquisició d'una segona llengua en general, i en la dels clítics pronominals d’una llengua romànica, en particular. Els resultats mostren que hi ha diferències entre els dos grups d'aprenents que són estadísticament significatives (ús del programa SPSS) i poden ser atribuïdes a les característiques de la L1.

The effects of teacher talk on students’ oral productions

The present study is a brief personal enquiry into the teaching and learning of EFL in the classroom with an orientation to action and personal professional development. It focuses on teacher talk, making special emphasis on questions, as well as on students’ resulting oral productions. The research contains samples of empirical data, which include their interpretations in the light of relevant research literature, and a more personal overall reflection of the teaching practice. Both the analysis and the reflections derive to a large extent from the self-observation paper 1 (SO1) and the Practicum portfolio (PP) developed within the TED Masters Degree practicum stages

Cooperative learning: learning to cooperate, cooperating to learn

This research project is an attempt to give arguments in favour of using cooperative learning activities in FL classrooms as an effective approach to learning. The arguments offered are presented from two different perspectives: the first one is based on the empirical study of three students working together to achieve a common goal. The second one is a compilation of the trainee teacher's experiences during her practicum periods in a high school regarding group work. This part is illustrated by some examples that emphasize that cooperative learning can facilitate learning, promote socialisation and increase students' self-esteem

A glimpse into classroom interaction

How does classroom interaction contribute to language learning? This study aims at identifying and interpreting some patterns of teacher-student interaction within an EFL classroom. Different interactional patterns and strategies are examined through the self-observation of the teacher's own performance as a student-teacher during her practicum period in a secondary school

Teacher strategies to elicit knowledge from students in the CLIL classroom: the purpose of questions in controlled patterns of teacher-student interaction

This Master Dissertation comprises two parts: a personal reflection and an empirical study. The personal reflection reviews the process of professionalization undergone by its author throughout the Master. The empirical study tackles teacher strategies to elicit knowledge from students in the CLIL classroom and more specifically the purpose of questions in controlled patterns of teacher-student interaction. The theories of relevant authors such as Vigotsky, Mercer and Tsui are used as a framework to analyze the data presented. The analysis shows the different strategies to elicit knowledge used by the teacher and the appropriateness of her questions in the analyzed interaction

The learning process as a cooperative task among teachers and students

This research project gathers several ideas and guidelines on professional improvement as a teacher. This study includes two empirical studies. The first one focuses mainly on the teacher's figure. It is meant to be a study of the several resources that the teacher uses in order to construct the student's knowledge in an English classroom context. The second empirical study focuses on the students. It is a study on how students learn cooperatively by analyzing their oral productions when working in small groups
