In the recent decades art education has tried to move away from the trends based on practical skills and techniques towards a greater stress on interpreting and understanding visual culture, created by the mass media. This approach implies a revision of the field of study and a redefinition of goals, replacing the study of art with a study of ‘visual culture’, a concept that better describes the daily environment of students and which reorientates art education towards social and cultural awareness. In this article, starting from Dewey's conception of art as experience, a theoretical framework is offered based on three ideas. Firstly, the subject of art education involves aesthetic experience, which includes both ‘high’ art and popular culture. Secondly, it is necessary to reconstruct the balance between understanding and production in art education, in order to consider art products as narratives, stories or comments about life experiences. Thirdly, to review the educational function of art education in order to determinate its value for social reconstruction and for which Rorty calls ‘self‐creation’.
. The diminution of the optimum sintering temperature and the widening of the Water atomised high vanadium M35M high speed sintering gate were proved. It was also demonstrated steel powders with different carbon contents were cold that sintering to full density of modified high carbon-high compacted at 700 MPa and sintered under an N 2 rich vanadium T42, T15, and M35M HSSs under 1150°C is atmosphere. Full density specimens were obtained at possible.10-12 This marks a historical milestone because temperatures between 1140 and 1105°C for carbon continuous mesh belt furnaces could now be used to contents between 1•8 and 2•5 wt-% respectively. The sinter HSS. sintering behaviour of these powder mixtures was cor-However, the interpretation of how nitrogen affects related with dilatometric curves and phase diagram sinterability was only made in a descriptive way. The aim calculations made by Thermo-Calc software. It is of this paper is to show the correlation between supersolidus demonstrated that densification takes place above the sintering behaviour and the nitrogen effect. The effect of solidus temperature, within the austenite+carbide+ nitrogen has been studied through the sintering behaviour liquid phase field, and that nitrogen widens this of modified M35 HSS. Experimental results have been region, which is responsible for increased sinterability explained under the basis of the supersolidus theory and with regards to vacuum sintered high speed steel.the phase diagrams obtained by Thermo-Calc software PM/0836 and the SSOL databank.

Educational practices in art museums are determined, to a great degree, by ideas of art and interpretation put into play, consciously or not, by both museums and educators. This article presents the results of research conducted at Tate Britain in which we have analysed the concepts of art and interpretation that underlie the discourses of the educators interviewed in this gallery. To this end we have designed a methodological device, a model that proposes four ways of understanding and interpreting art commonly found in educational contexts. This model has arranged the various conceptions from more visual or perceptual approaches to the most experientially complex as those summarised below: works of art as a visual representation and interpretation as identification; works of art as a message to be revealed, and interpretation as decodification; works of art as an intellectual, historical and cultural fact, and interpretation as an opportunity for critical reflection; works of art as the materialisation of an experience, and interpretation as an opportunity for self-development. We conclude that in interviews with educators working in the Tate Britain different narratives about the idea of art and the idea of interpretation coexist, which in many cases are complementary and in some others are contradictory. Examples of the interviews are presented throughout the article.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
