Hacia un lenguaje gráfico en la enseñanza

En este trabajo se parte del supuesto de que el uso de recursos gráficos, además de ser positivo, está creciendo continuamente en la enseñanza. Con el fin de facilitar la utilización de recursos gráficos en la realización de transparencias, mapas mentales, mapas conceptuales, resúmenes, etc., se proponen unas reglas básicas que constituyen en sí mismas un lenguaje gráfico     

Estrategias de conteo implicadas en los procesos de adición y sustracción

Resumen

A lo largo del presente trabajo se analizan las diferencias existentes entre los diversos procesos puestos en juego por los sujetos a la hora de cuantificar lo real, destacando de entre ellos el subproceso de cuantificación extensiva métrica y uno de los esquemas básicos que lleva aparejados: el esquema de conteo. A continuación se pasa a analizar las diferentes estrategias utilizadas por nuetros escolares de 1°, 2°, 3° y 4° de E.G.B. cuando aplican este esquema para la resolución de algoritmos de adición y de sustracción, destacando la vinculación entre el desarrollo de las estrategias de conteo y la eficiencia en la solución de estos algoritmos.     

Professional and Personal Competency Development in Near-peer Tutors of Gross Anatomy: A Longitudinal Mixed-methods Study

There are many benefits to peer and near-peer tutoring. The current literature suggests that near-peer teaching within the domain of gross anatomy may lead to the development of numerous competencies for burgeoning medical professionals. The aim of this study was a quantitative and qualitative approach to explore which professional and personal competencies anatomy tutors developed as a result of their teaching activities in a gross anatomy course at a medical school in Germany. For a period of 18 months, 24 peer tutors were followed and queried multiple times via questionnaire and semi-structured interviews. It was found that most of the skills tutors developed or strengthened over one semester matched most of the core competencies described in various official competency frameworks used for physician education. In particular, tutors thought that tutoring gross anatomy had improved their knowledge of professional behavior as well as their communication skills. They also felt that they had learned to take on more responsibility and to use available resources more effectively. Overall, tutoring gross anatomy was perceived as very challenging, but also very rewarding, mainly because it provided the opportunity to develop and strengthen important skills such as self-confidence, self-awareness, positive thinking, self-insight, and stress management. Ultimately, these are all factors that contribute to resilience, an important attribute for physicians.     

Action research through lesson study for the reconstruction of teachers’ practical knowledge. A review of research at Málaga University (Spain)

ABSTRACT

This article aims to set out our discussions, reflections and research at Málaga University (Spain) in relation to Lesson Study (LS), as a cooperative action research process. The paper aims to summarise the main findings of ten years of research, addressing the concepts and dilemmas found both in forming teachers’ practical thinking and in the complex processes of reconstruction through LS. The results of our research provide evidence that it is a useful way to deal with the reconstruction of teachers’ practical knowledge in teacher training. Teachers’ practical knowledge should be more broadly seen as an active combination of theoretical knowledge, procedural knowledge and skills, attitudes, emotions, believes, and values: i.e. teachers’ practical thinking. Most of these personal and professional resources are unconscious, or rather sub-conscious. Changes in teachers’ practical thinking require more practical experience and reflexion: a dialectical process based around two key components: theorisation of practice and experimentation of reconstructed theory. The results of our research show that these dialectical process could be developed with LS as a particular way of developing AR, adding a complex, systematic, flexible and cooperative way of dealing with specific and contextual curricular innovation projects. We therefore conclude that LS could be a very useful path to follow in reconstructing teachers’ practical thinking from within, strengthening the professional teaching community.     

The influence of the family,the school,and the group on the environmental attitudes of European students

The attitudes of young people arise from an intense interaction with their social groups of reference, and in this work we examine the extent to which this background conditions the individual environmental attitudes of the young. Using data provided by the PISA 2006 survey for the European Union, we test for the influence of the family, the characteristics of the school, and the social interactions or school peer group on attitudes toward the environment. The existence of social interactions, as well as the important role of family characteristics and school activities, are confirmed. The results allow us to emphasize the importance of the social context of the adolescent, and the need to take this into account as a channel that amplifies the influence of specific environmental education strategies.     

Negative certainty

The definitions of ‘negative knowledge’ and the studies in this regard published to date have not considered the categorial distinction Wittgenstein established between knowledge and certainty. Hence, the important role that certainty, despite its omission, should have in these definitions and studies has not yet been shown. In this article, I contrast the term ‘negative certainty’ with that of ‘negative knowledge’ in order to clarify this concept by describing its significant differences with the first. To characterize negative certainty, I base upon two criteria: on the one hand, negative certainty cannot be directly excluded by a positive certainty, and on the other hand, negative certainty must have an obvious and practical usefulness in which its negative nature is clearly appreciated. To illustrate the use of these two criteria, I describe four examples of negative certainty, paying special attention to their educational implications as well as the contrast between negative certainty and negative knowledge.     

Secondary School Students’ Errors in the Translation of Algebraic Statements

In this article, we present the results of a research study that explores secondary students’ capacity to perform translations of algebraic statements between the verbal and symbolic representation systems through the lens of errors. We classify and compare the errors made by 2 groups of students: 1 at the beginning of their studies in school algebra and another 1 completing their studies on algebra in compulsory education. This comparison allows us to detect errors which require specific attention in instruction due to its persistence and to identify errors that disappear as students advance in their study of algebra. The results and conclusions have a pedagogic value to inform instruction and also lead to backed conjectures and research questions to push forward research on student’s translation capacity and students’ knowledge of algebraic symbolism.
