Deficiencias en el trazado de gráficas de funciones en estudiantes de bachillerato

Este trabajo trata sobre el concepto de función, básico en el Análisis Matemático, y, en particular, su representación gráfica. Nos centramos en aspectos relacionados con la forma; es decir, el trazado de dicha representación. Analizamos las representaciones gráficas de funciones existentes en los cuadernos de matemáticas de estudiantes de varias aulas de 1º de Bachillerato. Encontramos deficiencias en el trazado de gráficas que se repiten en un alto número de estudiantes, relacionadas con los conceptos de función y asíntota, con el uso de las escalas en los ejes del diagrama cartesiano y con las características de algunas funciones. Además, discutimos sobre las limitaciones técnicas y las dificultades didácticas y cognitivas que pueden dar lugar a su aparición y hacemos algunas recomendaciones didácticas al respecto.

Social Work and theatre: considering intersections

Theatre is a cultural and artistic form that involves a process of communication between creators and is received in a space and time located in the public sphere, which has meant that, over the centuries, it has acted as a space for expression, exchange and debate regarding all manner of ideas, causes and struggles. Implicit within this process are processes of expression, creation and reception, by way of which people demonstrate, analyse and question ways of seeing and understanding life, and ways of being and existing in the world. This gives rise to educational, cultural, social and political potential, which has been endorsed in numerous studies and investigations. In this work, in which theoretical orientation is established through a review of the relevant literature, we consider different intersections that occur between theatre and social work in order to also show that dramatic and theatrical expression offers substantive methodologies for achieving some objectives of social work, particularly in areas such as critical literacy, reflexivity and recognition, awareness raising, social participation, personal and/or community development, ownership of cultural capital and access to personal and social wellbeing.

La otra Ley de Foucault. Una lectura crítica

Few studies have addressed the relationship between law and power in the works of Michel Foucault. Some authors emphasize that law performs a completely secondary role in the diagram of power of modernity, while others argue that there is a close link between power relations and the law. Foucault's Law by Golden and Fitzpatrick aims to renew these discussions and reconstruct another law of Foucault. In this paper I make a critical reading of this work, highlighting the faulty presentation that the authors carried out of the works of Foucault.

Use and access to ICT in students of public secondary schools in Chihuahua City, Mexico: inclusion in teaching and digital literacy

This paper addresses the issue of the digital divide in students of public secondary schools at Chihuahua City, Mexico. It seeks to identify potential inequality of opportunities with regards to subjects’ access to information, knowledge and education through the ICT (internet, mobile telephony, broadband and television). The study takes three schools as investigative stage, using the survey as a data collection instrument, identifying patterns of behavior regarding: general knowledge of them, access to computer equipment and internet, and characterization of their use. Other aspects of analysis are the identification of the educational level of parents and access to technology resources available for academic and non-academic purposes in various application areas (home, school and social environment). The proposal concludes, that it is through the recollection of alternatives suggested by the teachers themselves to incorporate ICT for teaching purposes in a systematic and planned fashion, whose greatest reflection manifests in better digital literacy indicators.

The in-service teacher trainer: profile, career path and duties

This article is the result of a doctoral thesis that aims to understand the reality of teacher trainers at a given moment, when their professional role changes from being a managing training advisor to a role that is more centred on process counselling. Using in-depth interviews, we defined the personal and professional profile of training counsellors in the Balearic Islands, their career path, the process for their inclusion in Teacher Centres (CEP) and, finally, the duties and skills that they perform as teacher trainers. The data that has been collected shows the coexistence of different professional roles in the group of education advisors. Moreover, it also indicates a lack of definition of the profile needed to access an advisor's position. There are indeed some coincidences determining the access route to such a position when it comes to the teaching profession since their leadership qualities and group dynamics expertise are a common indicator in most cases. The research also shows that they are subjected not only to a wide range of roles and tasks but also to a vast array of competences required to tackle the education advisor's tasks.

Programas iconográficos en "La piel que habito" (Almodóvar, 2011)

Como viene siendo habitual en las últimas películas de Pedro Almodóvar, las imágenes de La piel que habito (2011) se organizan en programas iconográficos que en este caso emanan de operaciones “trans” realizadas tanto en el cuerpo (transexualidad, transgénesis y trasplante), como en el texto (transtextualidad). El presente trabajo se ocupa de la genealogía y formalización de dichos programas así como de cuestiones teóricas surgidas a lo largo del desarrollo de este estudio –la relación entre cuerpo e identidad o el llamado muro de pantallas, entre otras–, de indudable calado en el filme.
