Utilización de la historia de las matemáticas en clase con alumnos de 6 a 13 años

En mi conferencia consideraré varias maneras de utilizar la historia de las matemáticas en la didáctica de las matemáticas para la escuela obligatoria; se trata de experiencias y reflexiones relacionadas con la elaboración y la experimentación de currículos para la enseñanza de las matemáticas en las edades comprendidas entre los 6 y los 13 años, desarrollados a partir de 1975 en el grupo de universitarios y enseñantes que coordina personalmente en Génova. El trabajo se ha efectuado en colaboración con Elda Guala; algunos artículos relacionados con estas cuestiones ya han sido publicados o están en curso de publicación.

Historia de la matemática: implicacioones didácticas

Saber cómo ha evolucionado y cómo evoluaciona la ciencia matemática ayuda a entender mejor las conexiones entre diferentes conceptos y procedimientos que la vertebran y permiten apreciar la naturaleza viva y humana. Como consecuencia, estos conocmientos contribuyen sin duda a enseñar mejor esta ciencia.

Didáctica e historia de las matemáticas

Nuestro trabajo en la E.U. de Formación de Maestros de Ciudad Real, nos ha ofrecido la posibilidad de orientarnos hacia un campo muy específico de las matemáticas como es el de su didáctica. En los estudios universitarios de la Licenciatura de Matemáticas hemos recibido una formación vacía en Didáctica. Ha sido pues el trabajo con nuestros alumnos en el aula, la búsqueda de libros, cursos y compañeros interesados en este tema, los que han posibilitado esta experiencia.

De la resolución de ecuaciones polinómicas al álgebra abstracta: un paseo a través de la historia

Realizaremos un paseo histórico a lo que ha sido la resolución de ecuaciones polinómicas y en general el desarrollo del álgebra. La intención es presentar una síntesis de algunas de las dificultades que se enfrentaron a lo largo de la historia, en la construcción de los significados y conceptos matemáticos, referidos principalmente a la resolución de ecuaciones polinómicas y al desarrollo del álgebra abstracta.

‘Martial races’ and ‘imperial subjects’: violence and governance in colonial India, 1857–1914

This essay explores the specificity of colonial violence in India. Although imperial and military historians are familiar with several instances of such violence—notably the rebellion in 1857 and the 1919 massacre at the Jallianwalla Bagh in Amritsar—there is a broader, and arguably more significant, history that has largely escaped attention. In contrast to metropolitan European states, where sovereignty derived, at least in principle, from a covenant between subjects and government, the sovereign power of the colonial state was always predicated on the violent subjugation of ‘the natives’. However, while violence was integral to colonialism, such violence was never a purely metropolitan agency: most of those recruited to serve in the colonial military were, themselves, Indian. Exploring the history of the imperial military in South Asia after 1857, the paper outlines the complex and rather ambiguous relationship between the colonial state and its ‘native armies’. RESUME Cet article se penche sur la spe´cificite´ de la violence coloniale. Malgre´ des exemples familiers—comme la grande re´volte de 1857 en Inde ou le massacre de Jallianwalla Bagh a` Amritsar en 1919—il y a une histoire plus large et plus importante qui a e´chappe´e a` l’attention des historiens. Contrairement aux e´tats europe´ens ou la souverainete´ de´rivait en principe du moins d’un contrat social entre les acteurs sociaux, le pouvoir souverain de l’e´tat colonial restait fonde´ sur la subjugation violente des indige`nes.

The Effects Of Reduced Salinity On Colonial Growth And Membership In A Hydroid

The effect of different salinity levels on colonial growth and gonozooid frequency of the hydroid Campanularia flexuosa Hincks has been studied. It is shown that the usual cumulative presentation of growth data tends to obscure evidence of acclimation and other features of importance to an interpretation of adaptations of the growth process to salinity changes. A method of analysis is described that not only demonstrates acclimation, but apparently shows how growth is controlled after disturbance by changes in salinity. One other response to reduced salinity and other unfavourable changes in water chemistry is an increase in gonozooid frequency due to the diversion of resources from the formation of new hydranths.

Outposts of Empire: Scientific Discovery and Colonial Displacement in Gaskell's Wives and Daughters

This article offers a fresh consideration of Elizabeth Gaskell's unfinished Wives and Daughters (1864–6), in terms of what this metropolitan novelist knew about contemporary scientific debates and imperial exploration of Africa, and how her familiarity with these discourses was incorporated into her imaginative work. Her focus for these two related themes is the naturalist Roger Hamley, whose character and exploits are meant to parallel those of the young Charles Darwin. Roger's direct involvement in the historical Geoffroy–Cuvier debate allows Gaskell to offer a sophisticated examination of how discussions about evolutionary biology (about which she learned from personal acquaintances and printed sources) contributed to political and social change in the era of the first Reform Bill. Roger's subsequent journey to Abyssinia to gather specimens allows Gaskell to form a link between science and imperial exploration, which demonstrates how, when carried to its conclusion, the development of classificatory knowledge systems was never innocent; rather, it facilitated colonial exploitation and intervention, which allowed for the ‘opening up of Africa’. Gaskell's pronouncements about science in the novel are far more explicit than her brief references to empire; the article ponders why this should be so, and offers some suggestions about how her reliance on imaginative and discursive constructs concerning the ‘Dark Continent’ may be interpreted as tacit complicity with the imperial project, or at least an interest in its more imaginative aspects.

The Violent Maintenance of the Portuguese Colonial Identity and the Search for a Postcolonial one: literary images of Portugal as a colonial and postcolonial nation

Through the examination of Camões's Os Lusíadas , Sena's Os Grão-Capitães and Saramago's A Jangada de Pedra , this article explores violence as a means of shaping Portuguese identity in different historical contexts, and how these works portray the continued recourse to violence as Portugal moves from colonizing to postcolonial nation.

Short reflections on the history of African communication

This article aims to propose a chronological subdivision in the history of African communication. African communication today is one of the most important axes for implementing development strategies, sustaining education, health, and schooling programmes, and so on. However, many of these programmes fail due to a lack of or ineffective communication between international organisations, local elite and lay people. The reasons for this situation must be found in Africa’s history of communication, which has undergone radical transformations in its different phases. Using the functionalist analysis drawn up by Jakobson, this article proposes a new chronological subdivision of Africa’s history of communication, reflecting on the current contradictions in contemporary communication in Africa.

Flavian laws, the railway, the newspaper and Loring’s breads

It is abound the research on the formation, rise and failure of the financial and industrial network undertaken by the Loring-Heredia-Larios triangle, bourgeois families who introduced the Industrial Revolution in the south of Andalusia. On the contrary, there are almost nonexistent studies from the perspective of the mentality that sustained their business, social and ethical model in the algid decades of their action (1850-1860). In this paper we propose some hypotheses about the ideological structures of bourgeois group and point out some keys, clues and signs for a future reconstruction of this kind, which so far has not been incardinated that early and failed malaguenan industrial revolution in streams thinking of that time.
