A brief consideration of the need for courses in the history and philosophy of science (HPS) for science teachers is followed by the development of a suggested addendum. The rationale accepts the developmental argument that a conscious awareness of personal uncertainty of explanation provides the motor of change needed to involve science teachers in thinking critically about the nature of their subject. Following the technique pioneered in a different context by Acredolo and O'Connor (1991), the addendum is developed as a test procedure fostering the expression of uncertainties in relation to important questions about science. Using questions designed to serve our specific purposes, a form of the test is trialled on a small group of science teachers attending courses in a Graduate Certificate in Science Education, and the results used to stimulate and promote their discussion of some critical matters concerning the nature of science. 相似文献

This article provides a model for the professional development of elementary science teachers. The model focused on integrating different domains of knowledge into science teaching, including the knowledge of the science curriculum, especially scientific inquiry, teachers knowledge, and students knowledge. The two case studies in this article revealed that the teachers construct their knowledge in a social context. The constant reflections on the experiences helped them to generate alternative teaching approaches. The findings suggest that the model of the project had two functions. First, it provides a useful strategy to help science teachers to bridge the gap between theories of teaching and their own teaching practices. Second, it provides a social learning environment for learning how to teach science. 相似文献

Résumé Le retournement de conjoncture du début des années 1970 s'est traduit par un renouveau des travaux relatifs aux cycles longs de type Kondratieff. Face à la fluctuation atypique de certaines variables (prix, production, etc ...), les acquis théoriques antérieurs semblaient avoir épuisé leur capacité explicative. Il devenait nécessaire d'énoncer et de vérifier des hypothèses nouvelles pour expliquer les traits originaux de la crise de structure qui se dessinait. Les résultats des travaux développés au sein du groupe de recherche en Histoire Quantitative et Théories du Long Terme de l'Université de Montpellier I répondent à cette nécessité. Ils introduisent une relation entre les dépenses engagées pour le développement des hommes (salaires, éducation, santé etc ...) et celles consacrées à la croissance matérielle.
The downturn in the economic situation in the early 1970s gave rise to new work on long-term Kondratieff cycles. Given the atypical fluctuation in some variables (prices, production, etc.), previous theories appeared to have exhausted their ability to explain events. To explain the original features of the structural crisis that was developing, it has become necessary to put forward and test new hypotheses. The results of work carried out by the research group on Quantitative History and Long-Term Theories at the University of Montpellier I meet this requirement. They introduce a relationship between expenditure on human development (wages, education, health, etc.) and that devoted to material growth.
Zusammenfassung Die Verschlechterung der wirtschaftlichen Situation in den frühen 70ern gab der Arbeit an langfristigen Kontratieff — Zyklen Aufschwung. In Anbetracht der atypischen Fluktuation einiger Variablen (Preise, Produktion, usw.) schienen vorangegangene Theorien die Ereignisse nicht mehr erklären zu können. Um die Ursachen der sich entwickelnden strukturellen Krise erklären zu können wurde es notwendig, neue Hypothesen aufzustellen und auszuprobieren. Die Ergebnisse der von der Forschungsgruppe über Quantitative Geschichte und Langzeittheorien an der Universität von Montpellier I durchgeführten Studien erfüllen diese Anforderungen. Sie stellen Ausgaben für die menschliche Entwicklung (Lohn, Bildung, Gesundheit usw.) und Ausgaben für materielles Wachstum in Relation.
Resumen La degradación de la situación económica a comienzos de los a~nos setenta ha originado un nuevo trabajo sobre ciclos Kondratieff de largo plazo. Dada la fluctuación atípica de algunas variables (precios, producción, etc.), las teorías previas aparentemente habían agotado su capacidad de explicar los hechos. A efectos de explicar las características originales de la crisis estructural que se estaba desarrollando, surgió la necesidad de adelantar y comprobar nuevas hipótesis. Los resultados del trabajo realizado por el grupo de investigación de Historia Cuantitativa y Teorías de Largo Plazo de la Universidad de Montpellier I satisfacen estos requisitos. Ellos introducen una relación entre los gastos y esfuerzos destinados al desarrollo humano (salarios, educación, sanidad, etc.) y aquellos dedicados al crecimiento material.

European identities may be politonymic, toponymic, ethnomyic or linguonymic (Bromley 1984). Each dimension may affect whether migrant minorities are treated as European, and influence their schooling, integration and rights. Treatment and terminology vary in different states and periods of migration. However, the position for immigrated minorities is that they are still largely seen as workers rather than human beings with equal rights. Lack of success in schools is blamed on the migrants themselves rather than the educational system. This construction of migrants as being deficient is parallel to educational practice which falls within a UN definition of linguistic genocide, and contributes to mis-education. If current efforts in international bodies to codify educational linguistic human rights were to lead to greater support for minorities, this could assist in a redefinition of national identities and a reduction of racism and conflict.
Zusammenfassung Europäische Identitäten können politonym, toponym, ethnonym oder linguonym sein (Bromely 1984). Jede Gruppe kann darauf Einfluß haben, ob Migrantenminderheiten als Europäer behandelt werden und Schulwesen, Integration und Rechte respektiert werden. Noch werden immigrierte Minderheiten jedoch weitgehend als Arbeiter und nicht als Menschen mit gleichen Rechten angesehen. Schulische Mißerfolge werden eher ihnen selbst als dem Bildungssystem angelastet. Diese Darstellung von Migranten als defizitär entspricht derjenigen Handlungsweise im Bildungsbereich, welche unter die Kategorie des linguistischen Genozids definiert wird und welche zu einer mis-education beiträgt. Wenn gegenwärtige Bemühungen internationaler Gremien um die Kodifizierung der Rechte der Menschen auf ihre Sprache Minderheiten unterstützen, könnte dies zu einer Umdefinition nationaler Identitäten und einer Reduzierung von Rassismus und Konflikten führen.
Resumen Las identidades de los Europeos pueden ser politonímicas, toponímicas, etnomímicas o linguonímicas (Bromley 1984). Cada una de estas dimensiones puede influir en que minorías de inmigrantes scan tratadas de Europeos y con ello en su educación escolar, en su integración y en sus derechos. El tratamiento y la terminología varían conforme a los períodos y las circunstancias de la inmigración. No obstante, la posición que se adopta frente a las minorías inmigrantes es la de considerarlos en gran medida como trabajadores y no tanto como seres humanos de iguales derechos. La falta de éxito en los estudios se atribuye a los inmigrantes mismos, más que al sistema de educación. Esta consideración de los inmigrantes como inferiores es paralela a una práctica de la educación que cae bajo una definición de la Naciones Unidas de genocidio lingüístico y contribuye a la educación deficiente. Si los esfuerzos actuales que las organizaciones internacionales ponen en codificar los derechos humanos lingüísticos de la educación estuvieran destinados a brindar un mayor apoyo a las minorías, esto podría ayudar a definir con mayor precisión las identidades nacionales y a reducir el racismo y los conflictos.
Résumé Les identités européennes peuvent être politonymiques, toponymiques, ethnonymiques ou linguonymiques (Bromley 1984). Selon leurs affinités avec chacun de ces domaines, les personnes appartenant aux minorités migrantes sont considérées ou non comme européennes, et cela influence leur scolarité, leur intégration et leurs droits. La façon dont ces personnes sont traitées et la terminologie évoluent selon les différentes étapes et périodes de migration. Mais le plus souvent, les minorités immigrantes sont encore davantage considérées comme des travailleurs que comme des personnes bénéficiant des mêmes droits. Les échecs scolaires sont mis sur le compte des migrants eux-mêmes et non sur celui du système éducatif. Le fait que l'on considère les migrants comme inférieurs se reflète dans une pratique éducative que les Nations Unies appellent génocide linguistique et se traduit par une éducation inadéquate. Si les efforts actuels de la part des institutions internationales pour codifier les droits de l'homme en matière de pédagogie linguistique apportaient un plus grand soutien aux minorités, cela contribuerait à donner une rédéfinition des identités nationales et à réduire le racisme et les conflits.

This study is concerned with possible differences in interaction patterns between teachers and certain groups of students: high and low achievers, and boys and girls. Detailed and comprehensive records of all verbal teacher-student interactions, both public and private, were obtained through videotaping a grade 6 class in three different settings: mathematics, language and science. While there was much consistency in the way the teacher monitored in this study interacted with the different groups, some important differences occurred in the quality and quantity of his interactions with students perceived as best and weakest, and with boys and girls in mathematics classes. 相似文献

The purpose of this study was to examine perceptions of school effectiveness among parents, students, teachers and principals, and differences in their perceptions across school levels (primary vs. secondary) and types (religious state vs. non-religious state). Finally, the results were compared with school effectiveness indicators in the literature. A sample of all categories of subject in eight Israeli schools were interviewed (N=64). Analysis reveals that parents stressed school outputs, teachers stressed their skills and teaching processes, students emphasized both inputs and outcomes, and principals chiefly inputs. Religious schools gave more weight than others to values. These findings are broadly in line with the literature, but any comprehensive analysis of school effectiveness demands reference to all aspects of the concept.
Zusammenfassung Ziel dieser Studie war eine Untersuchung darüber, für wie effektiv Eltern, Schüler, Lehrer und Direktoren die Schule beurteilen und wie unterschiedlich diese Wahrnehmungen auf den verschiedenen Schulebenen und -arten sind (Primarstufe und Sekundarstufe, religiös und nicht-religiös). Danach wurden die Ergebnisse mit Indikatoren über Schuleffektivität in der Literatur verglichen. Man führte Interviews mit den Zielgruppen in acht israelischen Schulen durch (N=64). Die Analysen zeigten, daß Eltern am meisten Wert auf Schulergebnisse legten, Lehrer auf ihre Fähigkeiten und Lehrprozesse, Schüler empfanden Lernen und Ergebnisse als gleich wichtig und Direktoren interessierte hauptsächlich das Lernen. Religiöse Schulen legten mehr Gewicht auf Wertvorstellungen als andere. Diese Ergebnisse stehen im allgemeinen mit der Literatur in Einklang, aber jede umfassende Analyse der Schuleffektivität erfordert die Berücksichtigung aller Aspekte des Konzepts.
Resumen El propósito de este estudio residía en examinar las percepciones referentes a la eficacia de la escuela entre padres, estudiantes, docentes y directores, y las diferencias en sus percepciones a través de los diferentes niveles (primario vs. secundario) y tipos de escuelas (religiosas vs. laicas). Finalmente, los resultados se compararon con los indicadores de eficacia escolar establecidos en la literatura. Se ha interrogado a un grupo representativo de todas las categorias de sujetos en ocho escuelas israelíes (N=64). Los análisis revelan que los padres ponían énfasis en los rendimientos escolares, los maestros enfatizaban sus habilidades y procedimientos de enseñanza, los estudiantes enfatizaban tanto los esfuerzos como los resultados, y los directores, principalmente, los esfuerzos. Las escuelas religiosas, más que otras, adjudicaban una mayor importancia a los valores. Estos resultados coinciden de forma global con los datos que indica la literatura, pero todo análisis integrado de eficacia escolar exige la referencia a todos los aspectos del concepto.
Résumé Le but de cette étude était d'appréhender comment parents, élèves, enseignants et directeurs d'école perçoivent l'efficacité scolaire, et si cette appréciation est différente selon le niveau scolaire (primaire ou secondaire) et le type d'école (statut religieux ou laïque). En dernier lieu, les résultats ont été comparés avec les indicateurs de l'efficacité scolaire relevés dans la littérature. Un échantillon de chaque groupe de sujets de huit écoles israéliennes a été soumis à des entretiens. L'analyse révèle que les parents font valoir le rendement scolaire, les enseignants s'attachent à leurs compétences et leurs méthodes pédagogiques, les élèves soulignent à la fois le contenu des programmes et les résultats scolaires, et les directeurs d'établissement se concentrent en premier lieu sur les contenus pédagogiques. Les écoles religieuses quant à elles donnent davantage de poids aux valeurs. Ces résultats correspondent d'une façon générale à ceux de la littérature, mais toute analyse complète sur l'efficacité scolaire doit couvrir tous les aspects du concept.

This is a dramatization of a fictitious debate about the age of the earth that takes place in the Royal Institution, London, England, in the year 1872. The debate is among Sir William Thomson (later Kelvin), T.H. Huxley (Darwin's Bulldog), Sir Charles Lyell, and Hermann von Helmholtz. In 1862 Thomson published his celebrated and widely studied The Secular Cooling of the Earth that raised the post-Darwinian debate of the age of the earth above the level of popular controversy. He entered the debate with all the arrogance of a newly established science of the century, namely the recently drafted laws of thermodynamics. The debate is partly based on a lively exchange of comments and arguments that occurred between T.H. Huxley and William Thomson, starting in 1868, when Thomson addressed the Glasgow Geological Society. This long public discussion also involved the ideas and the work of geologist Charles Lyell and those of the celebrated German physicist Hermann von Helmholtz. The confrontation is between the unyielding physicists and the insecure biologists and geologists who required a much longer time for the age of the earth than the physicists were prepared to give them. However, the debate ends on a conciliatory note, suggesting that perhaps Sir William's storehouse of creation may contain a hereto undiscovered source of energy that is more bountiful than gravitational energy. 相似文献

This paper examines the impact of two major approaches to literacy programs — the linguistic and the sociolinguistic. The principal difference between the two perspectives is that the linguistic negates the importance of sociological and ethnographic factors in a person's attaining literacy, while the sociolinguistic magnifies these influences. From one viewpoint, literacy is seen as cracking a linguistic code, while from the other, in Freire's (1987) phrasing, reading the world is necessary before reading the word. Academic/cultural literacy and functional literacy are examined as types affiliated with the linguistic perspective. Types of ethnographic literacy programs are analyzed to show their sociolinguistic orientation. The last section of the paper examines the language planning consequences of which perspective a country adopts and focuses on some recent literacy programs in Peru which incorporate elements of both the linguistic and sociolinguistic perspectives.
Zusammenfassung Dieser Artikel untersucht den Einfluß zweier Ansätze zu Alphabetisierungsprogrammen — den linguistischen und den soziolinguistischen. Der Hauptunterschied zwischen beiden Perspektiven liegt darin, daß die linguistische die Bedeutung soziologischer und ethnologischer Faktoren beim lernen verneint, während die soziolinguistische Perspektive diese Einflüsse unterstreicht. Eine Seite versteht unter Lese- und Schreibfähigkeit die Lösung eines linguistischen Codes, während die andere Seite mit Freires (1987) Worten gesprochen, Lesen der Welt in seiner Wichtigkeit vor Lesen des Wortes stellt. Akademische/kulturelle Schreib-u. Lesefähigkeit und funktionelle Schreib- u. Lesefähigkeit werden als Beispiele untersucht, die eng mit der linguistischen Perspektive verbunden sind. Ethnographische Alphabetisierungsprogramme werden in ihrer soziolinguistischen Orientierung analysiert. Der letzte Teil des Artikels setzt sich mit den Folgen für Sprachprogramme auseinander, in Bezug zur eingenommenen Perspektive. Der Artikel konzentriert sich auf einige Alphabetisierungsprogramme in Peru, die beide Perspektiven einbeziehen.
Resumen El trabajo examina el impacto de dos importantes enfoques de programas de alfabetización: el lingüístico y el sociolingüístico. La principal diferencia entre ambas ópticas reside en que la lingüística niega la importancia que revisten los factores sociológicos y etnográficos para la persona que está aprendiendo a leer y a escribir, mientras que la sociolingüística magnifica estas influencias. Desde un punto de vista, la alfabetización es considerada como la solución del código lingüístico, mientras que desde el otro, según las palabras de Freire (1987), se sostiene que antes de reading the word (leer la palabra) será necesario reading the world (interpretar el mundo). Estudia la alfabetización académico-cultural y la alfabetización funcional como disciplinas asociadas a la óptica de la lingüística. Analiza tipos de programas etnográficos de alfabetización para mostrar su orientación sociolingüístca. La última parte del trabajo examina las consecuencias de la planificación del lenguaje según la perspectiva que un país adopta, y enfoca algunos programas de alfabetización recientes del Perú, que incorporan elementos tanto de la óptica lingüística como de la sociolingüístic.
Résumé Cet article étudie l'incidence des deux principaux modes d'approche des programmes d'alphabétistion, l'un linguistique et l'autre sociolinguistique. La différence principale entre ces deux perspectives est la suivante: La linguistique nie l'importance des facteurs sociologiques et ethnographiques dans le processus d'alphabétisation d'une personne, alors que la sociolinguistique amplifie ces facteurs d'influence. La première considère l'alphabétisation comme le décryptage d'un code linguistique, pour la seconde, selon l'expression de Freire (1987), il faut lire le monde avant de lire le mot. Les formes d'alphabétisation dites académique, culturelle et fonctionnelle sont présentées comme appartenant à l'optique linguistique. Des programmes d'alphabétisation ethnographique sont également examinés pour en montrer l'orientation sociolinguistique. La dernière partie de l'article analyse les conséquences sur la planification linguistique quand un pays adopte l'une ou l'autre conception, et termine par la présentation de quelques récents programmes d'alphabétisation au Pérou, qui intègrent des éléments à la fois linguistiques et sociolinguistiques.

Scientific thought is regarded here as both a type of goal-directed behaviour (practice) and its product, and the question of its nature posed in terms of that goal and of means appropriate for achieving it, preferably with regard to an existing paradigm (exemplar) such as the Galilean-Newtonian. Empiricism, a widely received view of the nature of science, is examined and rejected, as is the general idea that scientific thought has philosophical foundations. The question of the actual or possible scientific status of the human sciences is raised and some methodological guidelines for an answer to it suggested.This paper is a version of one commissioned for the forthcoming International Handbook of Science Education edited by Ken Tobin and Barry Fraser (Kluwer Academic Publications). Thus it deals in a condensed way with wide-ranging and complex matters that would ordinarily be treated separately and at greater length. (Editor) 相似文献

This paper reports selected findings from the first stage of a study on the research role within academic work in Australian universities. These findings come from the interview component of the study and discuss the perceptions that senior academic administrators hold on research and scholarship. The analysis of the interviews indicates that research covers a wide and varied range of activities across the disciplines found in a university and therefore needs to be defined broadly. However, research has three major attributes: new knowledge, enquiry and publication of results and views. Scholarship was perceived to be part of the research process, providing the context for good research by adding the element of breadth to the depth of research. In addition, scholarship describes the manner of pursuing a serious, sustained line of enquiry as well as the dissemination process. 相似文献

The two concepts law and theory are among the most important elements of the nature of science. They represent both the tools and products of science itself. Unfortunately, the variable meanings and use of these terms in general discourse and in other school disciplines results in much confusion with respect to their proper application in a science context. The project included the design of a six-part model definition for law and theory based on a review of the literature of the philosophy of science with special reference to biology. These model definitions were then compared with those provided in a range of U.S. secondary school biology textbooks. The majority of all current major U.S. secondary school biology texts were reviewed and analyzed with respect to how the concepts of law and theory were defined and applied, in an attempt to determine whether students and teachers using such texts would gain an accurate impression of these terms and the distinction between them. This study focuses on biology instruction since a life science course is completed as a graduation requirement by virtually all U.S. high school students and as such serves as a widely shared educational experience across the nation. The term law is rarely defined in any text but various laws such as those found in genetics are frequently included as examples. The term theory is frequently defined but with a wide range of completeness of the definitions. Only rarely are theories in biology included as examples. 相似文献

Significant claims about science education form an integral part of Thomas Kuhn's philosophy. Since the late 1950s, when Kuhn started wrestling with the ideas of normal research and convergent thought, the nature of science education has played an important role in his argument. Hence, the nature of science education is an essential aspect of the phase-model of scientific development developed in his famous The Structure of Scientific Revolutions, just as his later work on categories and conceptual structures takes its starting point in the transmission rather than the creation of concepts and categories. 相似文献

Teaching Partnerships: Early Childhood and Engineering Students Teaching Math and Science Through Robotics 总被引：1，自引：1，他引：0
This paper presents an innovative approach to introducing pre-service early childhood teachers to math, science and technology education. The approach involves the creation of partnerships between pre-service early childhood and engineering students to conceive, develop, implement and evaluate curriculum in the area of math, science and technology by using robotics and the engineering design process. In this paper we first present the theoretical framework for the creation of these partnerships. We then introduce an experience done at Tufts University in which three different forms of partnership models evolved: the collaborators model, the external consultants model and the developers model. We also present different case studies from this experience and finally we conclude with some remarks and observations for making this work scalable and sustainable in other settings and universities. 相似文献

The paper investigates conceptual relationships between the Continuous and the Discrete. Differentiation, integration and the fundamental theorem of calculus are based on corresponding operators and a corresponding theorem with functions on finite domains (discrete functions). The final section discusses the possibilities for introducing elements of a discrete analysis into the mathematics curriculum. 相似文献

There are considerable differences among mathematics teachers with regard to the quatlity of their way of developing mathematical knowledge in the classroom. Such differences are analysed. To develop mathematical meaning requires both a consistent presentation of the mathematical symbols and of the referential meaning of these symbols with respect to the given task. On the basis of this conception we assume that the quality of teaching will differ according to how teachers cope with the relation between these two sides of meaning. From a sample of 26 teachers, an expert teacher and a non-expert teacher were selected by means of classroom observation with scales of instructional quality variables. For each of these two teachers, two lessons introducing probability (sixth grade) are analysed. For this purpose, teacher and student contributions are coded. For the expert teacher, graphic visualizations of the development of mathematical concepts across time show soft transitions between the different aspects of mathematical meaning. These transitions are made possible by a consistent explication of the relation between formal symbols and the given mathematical task. In the case of the other teacher, explication of the relationship between the object side and the symbol side of mathematical meaning is much rarer, and there are sudden switches from one aspect of meaning to another. Further differences concern the handling of student contributions.We gratefully acknowledge the help of Wolfgang Barz, Regina Dietrich and Claudia Krüger with recording, transcribing or coding lessons.

In most jurisdictions around the world,governments, in the name of economiccompetitiveness, have imposed comprehensive andquite dramatic changes on state schools. Mostchanges require a more centralized and rigorouscurriculum for pupils, a plethora ofaccountability measures and mandatoryin-service for teachers, and carefully definedand more onerous responsibilities for schoolleaders. The province of Ontario is nodifferent. Since 1995, its educational systemhas experienced quite revolutionary changes– all instituted with break-neck speed. At thesame time most schools in Ontario are employinginternal change strategies to address theseoutside pressures. These change forces havecoalesced to redefine the work and lives ofteachers and school leaders in many intendedand unintended ways. There is a substantialliterature on both external and internal changeforces, but very little has been written aboutthe conjunction of these change forces with thepersonal side of change for teachers andleaders. Based on two studies undertaken by theInternational Centre for Educational Change atthe Ontario Institute for Studies inEducation/University of Toronto, this paperexamines the unintended consequences of thesechange forces on the teachers and principals ofone secondary school in Ontario, Canada. Theteachers and leaders of Lord Byron High Schoolare not averse to change and are generallyquite content to do whatever is in the bestinterests of their students. The school has along history of innovation and change and areputation for attending to a wide diversity ofstudent needs.Through the use of multiple conceptual lenses,this paper addresses the unintendedconsequences of systemic change to the schooland its teachers and principals. At a time whenteacher shortages and teacher morale aregrowing problems for many educationaljurisdictions, this investigation will point toan urgent need to build better bridges ofunderstanding between policy makers and policyimplementers, and for researchers to provideresearch that is more sensitive to the work andlives of real people in real schools. 相似文献

The growing world-wide sensitivity to the aspirations of indigenous peoples is to be welcomed. However, there is still a tendency which should be avoided: to lump the claims of indigenous peoples with those of minorities. Indigenous peoples are the heirs of long-established political, social and cultural communities which have been oppressed for centuries or victimized by policies of genocide or forced assimilation into the approved language and religion of the dominating community. These forms of destruction can only be truly ended by returning to indigenous peoples a degree of autonomy which will ensure that they have real control over their future. Indigenous peoples should be able to create institutions, including schools, where their languages, religions and cultures are permitted to flourish without interference.
Zusammenfassung Wachsende weltweite Sensibilisierung gegenüber den Bedürfnissen einheimischer Völker sind sicherlich begrüßenswert. Vermieden werden sollte jedoch die Tendenz, die Ansprüche einheimischer Völker mit denen der Minderheiten gleichzusetzen. Einheimische Völker sind Erben langansässiger politischer, sozialer und kultureller Gemeinden, die jahrhundertelang unterdrückt oder Opfer politisch motivierten Massenmordes wurden, oder aber die dazu gezwungen wurden, sich der Sprache und Religion der dominierenden Gruppe zu unterwerfen. Diese Art von Zerstörung kann nur dann endgültig beendet werden, wenn einheimischen Völkern die für eine wahre Kontrolle über ihre Zukunft nötige Autonomie zugestanden wird. Einheimische Völker sollten die Möglichkeit bekommen, Institutionen und Schulen einzurichten zur Pflege und Weiterentwicklung ihrer eigenen Sprache, Religion und Kultur ohne Intervention von dritter Seite.
Resumen La creciente sensibilidad que se registra en todo el mundo ante las aspiraciones de los indígenas es un hecho muy positivo. Sin embargo, aun subsiste una tendencia que debe evitarse: no deben agruparse las reivindicaciones de los indígenas con las exigencias de minorías. Los indígenas son los herederos de communidades políticas, sociales y culturales establecidas desde hace mucho tiempo, que fucron oprimidas durante siglos o víctimas de políticas de genocidios o de asimilación forzada a la lengua y a la religión oficial de la comunidad dominante. Estas formas de destrución solamente podrán suprimirse devolviendo a los indígenas un grado de autonomia que les asegure un real control de su propio futuro. Los indígenas deberían recibir la posibilidad de crear instituciones, e incluso escuelas, donde sus lenguas, religiones y culturas puedan florecer sin sufrir interferencias.
Résumé La sensibilisation croissante au niveau mondial pour les aspirations des populations autochtones doit être encouragée. Une tendance reste cependant à éviter: confondre les revendications des peuples autochtones avec celles des minorités. Les premiers sont les héritiers de communautés politiques, sociales et culturelles implantées de longue date, qui ont été opprimées pendant des siècles, ou sont devenues victimes de politiques génocides, ou encore forcées à l'assimilation de la langue et de la religion autorisées par la communauté dominatrice. On ne pourra mettre un terme définitif à ces formes de destruction que si les populations autochtones recouvrent un minimum d'autonomie qui leur assurera une maîtrise véritable de leur avenir. Les peuples autochtones devraient pouvoir créer des institutions, dont les écoles, où leurs langues, leurs religions et leurs cultures seraient libres de s'épanouir sans ingérence.

Understanding: ‘Knowledge’, ‘Belief’ and ‘Understanding’ 总被引：1，自引：0，他引：1
The following paper is intended as an exercise in friendly criticism of one of Harvey Siegel's and Mike Smith's (Knowing, Believing and Understanding, this volume). I'm in substantial sympathy with the general thrust of their paper and my remarks merely provide some criticism of their discussion's conceptual coherence and clarity and a correspondingly slightly adjusted version of what they have to say. My focus is limited to the conceptions of knowledge, belief and understanding and their inter-relationships in terms of which they offer suggestions to science educators. 相似文献

This paper analyzes the interpretations of equality and the equal symbol of the third-grade children who participated in a year long whole-class socio constructivist teaching experiment. These children initially interpreted the equal symbol as a command to perform an arithmetical operation; it was less natural to them to interpret it as a relational symbol to compare two quantities. By the end of the school year, children were able to conceptualize the quantitative sameness of two numerical expressions and describe it by using the phrase is the same as, the words equal or equals, or the symbols = or =s. These children expanded their conceptualizations of equality due to their active role in class discussions, the arithmetical tasks that took into account children's difficulties, and the teacher's intellectual sensitivity to strike a delicate balance between the force of teaching and the freedom of learning (Freudenthal, 1991, p. 55). 相似文献
