Starting from an analysis of the limits of the formation of of categorial concepts as an approach to formation of physics concepts, and an epistemological analysis of the concepts fundamental to the domain of mechanics, a teaching sequence was conceived of with as its purpose the study of how such concepts («formal» and «relational») can be mastered by pupils using inductive and axiomatic procedures. The experiment described examines the concept of momentum, introduced in the first year of the lycée. The analysis of the teaching sequence shows the limits of induction in the construction of the concept studied. The logging of properties defining this quantity showed itself to be only possible through a number of questions related to previously established relations between the quantities known to the pupils (mass and velocity). An analysis of pupils, behaviours showed that the comprehension of properties (transfer, invariance, additivity…) and of the relation ( \(\vec P = m.v\) ) present less difficulty than the mastering of operational invariants which permit the elaboration of representations of experimental situations (the selection and temporal sequencing of events, the division into systems, the analysis of interaction…) The rupture of modes thinking which then «imposed” the taking into account of such invariants also permitted a comprehension of the difficulties of the conceptual changes.  相似文献

Since the end of the 1980s, Brazilian histoty of education bas been redefined by new historiographical currents. The process of redefinition has taken on particular characteristics because of theoretical and institutional factors involved in the evolution of the discipline as afield of research. The new trends run counter to the historiographical model that dominated the post‐graduate programmes in education of the main Brazilian universities since the 1970s. This model originated in the 1930s and 1940s with the publication of reference works for educational history research. The present essay examines the process of reconfiguration of the discipline with a view to evaluating the restrictions that were imposed upon it.  相似文献

Resumé Le présent article est d'abord une analyse d'un enseignement dans lequel des élèves de douze ans ont traité des problèmes de pavages polygonaux et progressé à cette occasion dans leur apprentissage de la géométrie plane. L'analyse, qui a porté principalement sur les processus de pensée des élèves, aboutit à rassembler ces processus en deux catégories principales: ceux qui relèvent d'une pensée dite instantanée et qui se manifestent surtout par des constats ou des conjectures rapides, et ceux qui sont plutôt discursifs et apparaissent principalement dans les activités de dessin et l'argumentation des preuves.Cet article contient aussi une comparaison de l'enseignement mentionné ci-dessus avec celui réalisé par D. van Hiele sur le même thème et analysé dans sa thèse de doctorat (1957).
Forms of mathematical thought of twelve years old students at tiling problems
The main part of this paper consists in an analysis of the activities of twelve years old students solving problems of polygonal tilings and improving on this occasion their knowledge of plane geometry. The analysis, bearing principally on the thinking processes of the students, results in a presentation of these processes in two principal categories: those which belong to what may be called the instantaneous thinking and result mainly in the perception of some simple structures or in some swift conjectures, and those which are of a more discursive nature and appear mainly in the drawing activities and in the argumentation of the proofs.This paper contains also a comparison of the above mentioned teaching with the analogous one organized on the same theme (tilings of the plane) by D. van Hiele, and analysed in her Ph.D. (1957).

The main stages of the evolution of biology teaching in Africa, after the independence of the countries, have been a better adaptation of the curriculum contents to the natural and socio‐cultural environment of each country, i.e. to go beyond a simple formal adaptation and to conceive curricula closer to the needs of African societies, in line with their specific values, and fitting with the cultural level of the pupils and with the preoccupations associated with a peculiar economic and social environment; an improvement of the teaching conditions, which remain difficult due to the lack of teaching aids of all kinds; a promotion of educational research, thanks to the creation and the development of administrative bodies responsible for the training of teachers and for the supervision of their activities. African countries have universities, faculties or schools of education and teacher‐training institutes, which are in charge of the training of biology teachers for secondary schools; they also have adapted their programmes to their needs; but such in‐depth adaptation must continue, so that biology teaching responds better to social evolution, to the new conditions of economic and social change and to new ethical situations.

There remains a lot to be done in the area of elaboration and evaluation of teaching methods and techniques, bearing in mind the great difficulties of the teachers who lack the necessary minimum educational aids, specially in rural areas.

The UNESCO pilot project for the improvement of biology teaching in Africa (1966‐1972) is part of a series of projects dealing with the improvement of school programmes and sponsored by UNESCO. The teaching aids produced for the English‐speaking countries of Africa were a handbook and a teacher's guide concerning an initiation course of biology for the junior level of high schools, as well as a series of loop films for the classroom. The aids produced for the French‐speaking countries of Africa were for the senior level and included booklets and colour slides, for the teachers’ use and not the pupils'; the topics involved African ecology, plants and soils, introduction to human biology, conservation and preservation of biological resources.

As a contribution to the national endeavours of educational reform, UNESCO published in 1974 and 1975 the English, French and Spanish versions, adapted to Africa, Asia, and Latin America and the Caribbean, of a Teacher's guide on the biology of human populations. This meant to emphasize the necessary adaptation of biology teaching to its social and cultural environment, while presenting the human populations and their relations with their environments. This is a contemporary subject, which also allows the examination of the role of biology and biology teachers’ in the general awareness of environmental problems; a subject which does not need sophisticated equipment or teaching aids, but, rather, appeals to the observation skills of teachers and pupils.

It is true that the African experience has, to some extent, followed a trend which European countries acknowledged several years ago. Adaptation of curriculum content is a long‐term task and is pursued in both kinds of countries. The African experience could certainly be beneficial to European curriculum designers. The production of all kinds of teaching aids, of various degree of complexity, in the national language, as well as the evaluation of relevant teaching methods and techniques, are areas of acute shortage, where bilateral as well as multilateral assistance could be most fruitful.  相似文献

We are interested in the teaching of geometry to primary school (children from 3 to 11) teachers. We define a priori a conceptual frame, which organises geometry upon three kinds of knowledge: intuition, experience and deduction. Drawing on Gonseth's works, we bring out three syntheses of elementary geometry: natural geometry (geometry I), natural axiomatic geometry (geometry II) and formalist axiomatic geometry (geometry III). Next we illustrate this conceptual frame with examples of teaching geometry. Last we bring out different conceptions of geometry in scholar system which could lead to cross purposes.This revised version was published online in September 2005 with corrections to the Cover Date.  相似文献

Two major factors have contributed to the evolution of French historiography in the history of education in the past 50 years. The first relates to the general orientation of public debate about schools, which has shifted from a paradigm concerning democratisation to one that focuses on student success rates and the efforts to eliminate inequalities of all sorts. The second factor that has affected scholarly orientations lies in changes linked to academic positioning between pedagogy, history, and the educational sciences in the context of increasing university hirings, at least until recently. These two changes in terms of scholarly paradigms and scholarly professional identities have encouraged the development of a certain number of approaches and questions: a reconsideration of the historic role of the State, an interest in a greater diversity of actors in the educational process, and a re-evaluation of the cognitive, cultural and social effects of teaching at all levels. Despite this, the history of education plays a minor role today in France, not only in teacher training but also in debates about the future of schools.  相似文献

Resumen

El propósito de este estudio fue diseñar un modelo válido para la adquisición de unos adecuados hábitos de estudio, basado en una combinación de estrategias de autorregulación y técnicas de estudio. Se procedió mediante un diseño exploratorio de línea de base múltiple, con un único sujeto que incluía: a) fase de pretest, b) primera fase de intervención, en la que se introdujeron las estrategias de autorregulación, c) segunda fase de intervención o de introducción de las técnicas de estudio, y d) fase de postest. El resultado fue un cambio experimental y terapéuticamente significativo en los hábitos de estudio y en las conductas exponentes de: tiempo de estudio, desatención, y velocidad y comprensión lectoras, las calificaciones experimentaron un ascenso progresivo. Estos cambios se mantuvieron y consolidaron en el seguimiento, las estrategias de autorregulación se han mostrado útiles para aumentar la probabilidad de ocurrencia de la conducta deseada y disminuir la de la no deseada.  相似文献

In this paper we tackle the issue of an eventual stability of teachers’ activity in the classroom. First we explain what kind of stability is searched and how we look for the chosen characteristics: we analyse the mathematical activity the teacher organises for students during classroom sessions and the way he manages the relationship between students and mathematical tasks. We analyse three one-hour sessions for different groups of 11 year old students on the same content and with the same teacher, and two other sessions for 14 year old and 15 year old students, on analogous contents, with the same teacher (another one). Actually it appears in these two examples that the main stabilities are tied with the precise management of the tasks, at a scale of some minutes, and with some subtle characteristic touches of the teacher’s discourse. We present then a discussion and suggest some inferences of these results.

The Swedish physical education method has had a singular destiny in France. Originally created by the Swedish Per Henrik Ling (1776–1839), it first spread in France thanks to German doctors. From 1902, the Swedish method became the official method of the Ecole normale de gymnastique et d’escrime de Joinville. It caused serious dissension first within the army, between Georges Hébert, a naval officer attempting to spread his own method called ‘Méthode naturelle’, and Emile Coste, a major at Joinville school who was a resolute supporter of Ling’s method; then within Joinville school, where, from 1905, Georges Demeny, renowned physiologist, tried to impose his French method ‘Eclectique’. The three protagonists would use arguments focused on the rationality of the Swedish method to legitimize or criticize it. But this explicit stake based on the validity of the link between a scientific culture – anatomy and physiology – and a physical education method does not mask the implicit stake of real power.  相似文献

The struggle against illiteracy is a problem of great importance in Turkey as in many other countries. In Turkey the democratisation and secularisation of education have been a difficult process. Despite strong educational efforts in recent years, the country still presents various forms of inequality, such as considerable disparities between women and men, between town and country and between different regions. Unequal socio-economic, cultural and educational development, and attachment to cultural traditions are some of the factors that influence these inequalities. At the same time, Turkey is confronted by the sore problem of the education of linguistic minorities (especially the Kurds), who are not officially recognised as the cultural policy of Turkey aims to assimilate them. Thus, in the 1920s the Kurdish language was forbidden along with all languages other than Turkish, the official national language.  相似文献
