Medios, imágenes y memoria: el Valle de los Caídos

Since the first decade of the 21st century, the Valley of the Fallen has been established as an object of controversy related to the new policies of memory. In recent years the "Historical Memory" has been a recurring concept in the mass media. While it is true that since 2011 this issue has been overshadowed in the political agenda, even today we continue to access information that refers to our recent past, from perspectives that demand actions of ethic, symbolic, political or economic repair. Many of these reports could be framed within a broader discourse, akin to a concept of "historical memory". These media texts are part of a larger problem that is troubling modern western societies and that has presented a remarkable recovery since the late nineties: debates or polemics on memory. In this paper we propose to study the nature of these media texts. We assume that the mass media configure their texts from frameworks or pre-existing frames. For this research, we propose an analysis of content based on the theory of framing to identify what is the typical journalistic discourse and the modalities of interpretive general framework applied in a number of texts and broadcasts about the Valley of the Fallen...

Diseño y estudio de situaciones didácticas que favorecen el trabajo con registros semióticos

What’s behind the mistakes and difficulties that appear on the students to understand and study mathematics?are only related to the cognitive complexity of the content or such difficulties are also related to the possible ways to access the different mathematical objects? The mathematical activity generated in many students learning difficulties that are not manifested in cognitive processes related to other areas of knowledge. If something characterizes the processes of teaching and learning of mathematics is that, unlike what happens with the objects of study in the experimental sciences, the only way to access to them is through its different semiotic representations. The coordination among the different systems of representation that refer to the same mathematical concept, needs to move from one register to another (D’Amore, 1998, 2001, 2003, 2004, 2006; Duval, 1993, 1994, 1995, 1996, 2000, 2003, 2004, 2005, 2007, 2008, 2011, 2012; Godino, 2002, 2003, 2012, 2014; Kaput, 1989a, 1989b,1992, 1998; Radford, 1998, 2004a, 2004b, 2004c, 2006a, 2008,2009, 2011, 2013, 2014a). Therefore, the treatments that can be realized within a given register and the conversion of one register into another, play an essential role in the grasp of the object and mathematical concepts. Through this work with representations, students give meanings to the objects of study and are able to understand the underlying mathematical structures, which is the main educational interest of this issue...
