Representaciones estudiantiles de variación. Un estudio desde mediaciones pedagógicas

El propósito de esta investigación en curso es indagar sobre las representaciones que tienen estudiantes del nivel medio superior (secundaria y primer nivel universitario) acerca de nociones matemáticas variacionales, prestando especial atención a su forma de aprenderlas y buscando propiciar espacios de reflexión respecto de ellas, con el objeto de aportar información que sirva de base para la elaboración de diseños didácticos tendientes a mediar -en procesos de profundidad creciente- aprendizajes de nociones matemáticas variacionales, por ejemplo, la razón de cambio de una magnitud. Como técnica exploratoria consideramos el uso de bitácoras personales de reflexión de los estudiantes, para luego, en una segunda etapa, derivar en la construcción y aplicación de un cuestionario y la realización de entrevistas para triangular fuentes de información. En este artículo se reportan evidencias de la primera etapa, provenientes de las bitácoras personales, en el contexto de un curso de cálculo inicial.

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.

Unraveling EU Policies: the ““Common Basic Principles”” and the ““European Integration Fund”” as a technology of government

this paper is about EU “soft policies” on immigrant integration. It analyzes the “Common Basic Principles” (CBPs) and the “European Integration Fund” (EIF), two devices that have been recently established within this framework. It adopts the theoretical perspective of the “anthropology of policy” and “governmentality studies”. It shows the context of birth of the aforementioned devices, as well as their functioning and the assessment done by the actors implied in the elaboration/implementation/evaluation of the related policies. It is based both on documentary research as well as direct observation and interviews done to the actors implied. It concludes that the PBC and the EIF should be considered as a “technology of government”, that strives to align the conduct of the actors with the governmental aims, as well as it produces specific practices and knowledge. It also underlines an intrinsic feature of many policies: their “congenital failure”, since they are (often) disputed and resignified by situated actors, who are embedded in asymmetrical power relations.

Teacher attitudes and best practices with ICT faculty Adult Continuing Education in Andalusia

The present paper reports the results of a study aiming to describe the attitudes of teachers in adult continuous education in the Autonomous Community of Andalusia (Spain) towards the use and integration of information and communication technologies (ITC) in the educational centres they work in, while identifying those factors that favour the development of good practice. It is a mixed methods descriptive research, and information collection techniques include a questionnaire and in-depth interviews. A total number of 172 teachers were surveyed, as well as 18 head teachers and coordinators, in adult education. For questionnaire validation the expert judgment technique was used, as they were selected by the «expert competence coefficient» or «K coefficient» procedure. To improve its psychometric properties, construct validity was determined by means of Varimax factor analysis and maximum likelihood extraction (two factors were extracted). Confidence was set by Cronbach's alpha (0.88). The interview guide was also validated by this group of experts. Results point out, on one hand, that teachers hold positive attitudes towards ICT regarding both ICT's role in professional development and their ease of use and access. On the other hand, among the most important factors for ICT-supported good educational practices lies in ICT's capacity to favour personalized work.

Adaptation of a questionnaire to assess the epistemological beliefs of mathematics in secondary school teachers

The objective of the study is to determine the psychometric properties of the Epistemological Beliefs Questionnaire on Mathematics. 171 Secondary School Mathematics Teachers of the Central Region of Cuba participated. The results show acceptable internal consistency. The factorial structure of the scale revealed three major factors, consistent with the Model of the Three Constructs: beliefs about knowledge, about learning and teaching. Irregular levels in the development of the epistemological belief system about mathematics of these teachers were shown, with a tendency among naivety and sophistication poles. In conclusion, the questionnaire is useful for evaluating teacher’s beliefs about mathematics.

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.

The influence of experience on the research competencies of university professors

Implementation of EHEA, among others, motivates a transforming process in universities and promotes changes in the professor’s tasks. This events, promote changes to which the university professor has to adapt, meaning this to acquire and to develop new competencies to respond correctly to new professional tasks that are demanded. To design training plans in accordance to the new training needs, and to establish referents in accreditation, selection and promotion protocols appear to be necessary to define the new competences profile professors have to face in order to develop their teaching, research and management tasks suitably, and according to their professional settings and professional development stage. A qualitative research was developed to define the emerging competence profile. Quantitative and qualitative methods were mixed as well as different tools (questionnaires, interviews and focus groups) and sources (faculty, experts and students). This article only shows the results obtained from professors (expert and novice) in the 4 research competencies analyzed (design, development and assessment of projects; organization and management of scientific events; development of scientific material; communication and dissemination of scientific knowledges) and the most significant dates of the 30 competency units that compose them. Results show significant differences of self-perception of current competency domain level between novice faculty and expert faculty. These results help us to establish the priority training areas to the faculty according to their professional development stage.

El Prácticum de Maestro en las voces de sus tutores. Balance del plan 2010 en la UAM

Se aborda un análisis del desarrollo del Prácticum de Maestro derivado del plan 2010, particularmente dirigido a valorar los cambios acaecidos en relación con el plan 2000, desde el punto de vista de sus tutores profesionales. La metodología es de tipo cualitativo, con entrevistas a 6 tutores profesionales innovadores de la red de centros de una universidad pública y a los 3 responsables de la materia analizada en ambos planes. Entre los resultados se observa que la percepción sobre las transformaciones operadas en el desarrollo en los centros de esta materia son poco apreciables, así como que la tutela del Prácticum se construye mediante una fuerte relación interpersonal de tutelado y tutor y que está vinculada al tipo de enseñanza que practica. Ello tiene consecuencias en la redefinición futura del Prácticum.

Social networks and lifelong learning in older people

Various socio-demographic factors are causing our society to coexist every day with a group of elderly population that remains active and inserted into the daily dynamics. However, it is believed that there are certain barriers that make this group of people to not adequately address the technologies and even social networks. The creation of the University Programs for the Elderly (PUM), however, is leading to a new stage, since older people who participate come into contact with all kinds of content and rigor, updating own university education, thus changing the way to tackle the most innovative and different situations. In this study, we analyze what is the knowledge and use of older people, PUM, attending the University of Jaen have of the social networks and the assessment made of the need for these programs. To achieve this, we used a methodology in which qualitative and quantitative processes were articulated, through the analysis of data obtained from interviews and a focus groups with program Aquad 7. The data collected show that there is still some ignorance about social networks by older people, but everyone values their usefulness and necessity. Participants believe that they will be least affected of the risks of these technologies and demand a greater training in these contained within the PUM.

los MBA y el reclutamiento de las Escuelas de Negocios en Buenos Aires. Notas etnográficas sobre el mundo del management

In this article I study certain aspects that constitute the “grammar” of the field of management and business. By observing the way in which three prestigious business schools ‒one American, one Spanish and one Argentinean‒ present their offer in executive education ‒management business administration‒, I intend to reconstruct the way in which the reasons, the values and the justifications are structured. The article is based mainly on ethnographies carried out in the informative sessions that these three schools organized in luxury hotels in work of interviews and documentation’s analysis carried out in large Argentinean companies.
