Objetivación del conocimiento matemático: el caso de la función y el caso de la parábola

Es nuestro interés en este curso discutir algunos aspectos teóricos y metodológicos relativos a la objetivación del conocimiento matemático, específicamente el relacionado con el concepto de función y con el concepto de parábola. Haremos esta discusión desde algunos resultados obtenidos de la investigación “El conocimiento matemático: desencadenador de interrelaciones en la aula de clase”. En dicho estudio empleamos una metodología a la luz del paradigma cualitativo, bajo un enfoque crítico-dialéctico y desde una investigación colaborativa. Nos apoyamos teóricamente en autores que asumen una perspectiva sociocultural de la Educación y de la Educación Matemática, por ejemplo, Bajtin (2004, 2009), Caraça (1984), Moura (2001, 2010) y Radford (2004, 2006, 2008). Este estudio nos posibilitó comprender, entre otras ideas, que los conceptos que cada alumno objetivó con respecto al objeto función y al objeto parábola no fueron únicos; como no pueden serlo el proceso de objetivación, ni los conceptos mismos.

Objetivación del límite de una función: ¿pensamiento empírico o pensamiento teórico?

Presentamos un avance del proyecto de tesis de doctorado que estamos realizando en el marco del doctorado en educación, línea de educación matemática, de la Universidad de Antioquia. Este estudio tiene como propósito analizar la objetivación del concepto de límite de una función, de alumnas de grado once, a través del desarrollo de su pensamiento teórico. La perspectiva histórico-cultural de la educación sirve de fundamentación teórica en esta investigación, en especial la teoría de la actividad. El camino metodológico a seguir es de orden cualitativo, desde un paradigma crítico-dialéctico, y una investigación participante. El trabajo de campo se realizará en una institución escolar pública de Medellín.

Sesgos en el razonamiento probabilístico y efectos de la instrucción estadística elemental

En este articulo presentamos una investigación sobre el razonamiento probabilístico de estudiantes recién ingresados en la universidad. El trabajo se enmarca teóricamente en el paradigma de heurísticos y sesgos (Kahneman, Slavic y Tversky, i982) de tradición muy fecunda en el campo del pensamiento probabilístico. Además estudiamos los efectos de la enseñanza estadística que recibieron estos estudiantes en la enseñanza secundaria. Consideramos que de los resultados de la investigación se derivan ideas muy útiles para establecer un nuevo modelo de enseñanza de las probabilidades en la educación secundaria.

La resolución de problemas. Una revisión teórica

Según las orientaciones didácticas marcadas por el MEC para las matemáticas de secundaria obligatoria, la resolución de problemas es una de los ejes vertebradores del área a lo largo de la etapa, por lo que debe estar integrada como una actividad de presencia permanente en el aula. Este articulo es una mirada sobre los aspectos teóricos mas relevantes de la resolución de problemas. A partir de una revisión histórica, se examinan los principales modelos propuestos en la literatura. Se completa con un análisis de cierta profundidad sobre la propuesta de Miguel de Guzmán, entendida como síntesis y paradigma de los modelos anteriores.

The Sports Overload Injuries of the Lower Extremities from the Biomechanical Point of View

This work studies the major sports overload injuries of the lower extremities from the biomechanical point of view. At the same time, the main paradigms of podiatric biomechanics and the application of new biomechanical theories in the study of these lesions are reviewed. With current legislation, clinical gait biomechanical studies should be carried out in health centres and the only health professionals who can perform them are podiatrists and doctors (because they both can diagnose). Graduates in physical education can carry out studies in the field or in the sports court for the sole purpose of improving athletic performance, but never intended to treat a pathology overload.

Sports programs of the Spanish radio in the social network Facebook: compared study (2010-2015)

Social networks have increasingly become a showcase where the media can be promoted. Like many other media, radio stations have made use of social networks to promote themselves in a better way and, sometimes, to keep more feedback with their listeners. But not all programs make the same use and not all of them have managed to reach in the same way his followers. This article discusses the consolidation in the social networks of the major radio sports programs in Spain. Through a comparative analysis between 2010 and 2015, throughout the text, the authors have tried to observe the evolution of the programs and, at the same time, to establish comparisons between the followers that these programs have on social networks and the number of listeners as EGM.

Analysis of audiovisual production and music scene in Extremadura through YouTube channels

A study on Extremenian music and audiovisual production has been carried out through YouTube media. The purpose of this study is to analyze all audiovisual products and also assessing what broadcasting processes are conducted by creators to publicize their musical and audiovisual works. A quantitative and qualitative study of audiovisual materials of Extremadura bands was done to find out which processes are most suitable to increase the number of viewers for videos.

Intercultural competence in the area of drug dependencies

This article takes a multidimensional or biopsychosocial conception of drug dependency as its starting point. Within this analytical framework, we advocate making the intercultural dimension more visible, since it is essential for the design and implementation of integral intervention processes. We propose intercultural competence as a working model that can increase the capacities of institutions and professionals —a particularly important consideration in the case of social work— in order to effectively address the aforementioned cultural dimension. After an extensive review of the scientific literature, we have defined five processes that can contribute to strengthening an institution’s intercultural competence and four processes that can do the same for a professional’s intercultural competence. Though selected for application in the area of drug dependencies, all these processes can also prove useful in improving attention to any other kind of culturally diverse group or person.

The media on violence against women: the paradigm of thinness

This article attempts to show that the aesthetic pressure through the media, especially exerted on women, can be defined as gender violence; and the consequences of thinness paradigm of our society and obesity stigma that this entails have for their bio-psycho-social health.

Discourses on Modernization in the Employment Public Services: Towards a New Form of Governance?

The “crisis of the social issue” in the EU has led to a certain consensus in the need to renew the organizational and institutional model of public administration. The core of the reform implies important administrative changes in most of the European welfare states. Those changes are inspired on theories such as the new public management, management by objectives or partnership. Such changes involve both semantic (“sharing responsibilities”, “effective costs”, or the substitution of “citizen under an administration” by “consumer”) and political (predominance of scattered forms of power and the individualization of responsibilities) transformations which operate in the framework of individuals and State relations. The paradigms of activation and flexicurity have been central in this public administration modernization project. This commitment with new forms of governance of social issues has important consequences for the political and moral foundations of social cohesion, and the Spanish case is not an exception. This paper aims at looking at those representations of “modernization” (as they appear in debates about the employment services restructuring policies) in detail as well as providing references to the trajectory of such reforms of public services since the early eighties to the beginning of the crisis.

Scientifi c discourses on chronic pain without organic cause Incorporating gender perspective for pain resignifyng-repoliticizing

Chronic pain, without any organic or physical cause (DC), which in psycho-medical terminology is known as fi bromyalgia, (FM), is diagnosed each year to a considerable number of women in capitalistic societies. Our main interest in the following paper is to go in depth in the elaboration of this symptom, its treatment and the psychosocial effects, both in the social order as well as in the lives of the people who suffer from it. Our main goal in the following paper is to look deeper in the elaboration (conceptualization) of this symptom, its treatment and psychological affects, both in the social order as well as in the lives of the people who suffer from it, we are using linked speeches in Spanish magazines publications. The result has been the emergence of three hegemonic discourse positions: One position “scientist”, one “therapeutic of the conformity” position and one “economic and legalistic” position. Each of these has a specifi c feature, but on the whole, is enhanced, producing effects such as the absence of social context to explain the disease; disregard of gender differences in the management and treatment; the instrumentalization of pain to legitimize their practices and the subjection of women to the “psycho-biomedical” paradigm. In that way, a new signifi cance and politicization of the concept of pain is proposed.

Welfare Regimes and “progressive” governments in Latin America: The cases of Venezuela, Ecuador and Bolivia

Several authors have applied the concept of Welfare Regimens for studying social policy in Latin America (Esping-Andersen, 1993 and 2000). Among others, Martínez Franzoni (2007) develops a typology, with fi eld work is at the turn of the millennium, and establishes three categories: State-productivist regime, state-protectionist and family orientated. Most countries in the region are placed in the latter category. The hypothesis of this article argues that with the emergence of governments considered “left” or “progressive” in several countries of the region from the late ‘90s and, more decisively, in 2000’, the map of welfare regimes models could have mutated substantively. The nationally transformative experiences are different (various socio-economic realities and political action in which they are located exists) but they have several contact points that can be summarized in a greater state intervention in different areas previously closed to their operating and recovery of important functions of welfare and care of the population by the government. The paper discusses with an exploratory and descriptive approach the welfare schemes that would shape in three countries that have constitutionalized the change from the neoliberal paradigm: Venezuela, Bolivia and Ecuador.
