Training,stability and control   总被引：1，自引：0，他引：1  
This paper presents a system-theoretic approach to the analysis of the problem of training formally relating it to the control of an abstract dynamic system, the adaption automaton of the trainee. The utility of this formulation and the possibility of basing real training strategies upon it are discussed, and it is argued that further constraints upon the automaton are both necessary, and available, in so far as the theory corresponds to practical reality. The minimal constraints generate an extended theory in which training is related to the stability of the adaption automaton. More practical constraints lead to theoretical foundations for strategies of feedback or adaptive training. Corresponding to each set of constraints a training theorem is proved which demonstrates that the constraint is adequate to lead to a simple universal training strategy.Although this paper is highly theoretical it is argued that the formal concepts introduced correspond to intuitive models of the phenomena of learning and training which are implicit in the design of many training systems. It is hoped that the formal analysis will throw new light on these implicit assumptions and help to clarify discussion of practical approaches to training, including the possibility of computer-aided instruction given on our present level of knowledge of human cognitive skills or individual students.  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.

The errors made when high-school students locate reflections in horizontal, vertical or slanting mirrors were examined. A questionnaire consisting of thirty-six perspective drawings, each portraying an upright transparent cube containing a two-sided mirror, was given to 394 Australian students from grades 7, 9 and 11. On a corner, an edge, or a face of each cube was drawn either a point or a straight-line segment. The task was to draw its image (reflection). Analysis of errors revealed a strong tendency towards horizontal or vertical sliding, suggesting that the edges of the cube act in much the same way as a horizontal-vertical background grid does in the two-dimensional case.  相似文献

The education system is widely perceived to be functioning poorly, and this paper argues that there is in fact a deep crisis caused by the gap between the system and the changing world that surrounds it. Post-modern conditions stress the production of information rather than the productivity of land or capital, and a relativistic world-view rather than adherence to a fixed religion or ideology, which in turn gives rise to pluralism and shifting social frameworks. At the same time, the pursuit of Truth is no longer seen as the highest goal in life, and the possession of proof of education is no longer a guarantee of access to the Good Life. Educational institutions are dysfunctional because they remain wedded to outmoded parameters in their aims, activities, structures, methods and perceptions of their clientele. Through a wide-ranging review of recent conceptual debate and assessment of social trends, the paper explores the implications of radical contemporary changes in the parameters: the search for a new paradigm of education has only just begun.
Zusammenfassung Das Bildungssystem wird weitgehend als unzulänglich betrachtet, und dieser Artikel argumentiert dahingehend, daß es in der Tat eine tiefgreifende Krise gibt, die durch die Kluft zwischen dem System und der sich ändernden Welt um es herum ist. Postmoderne Bedingungen legen eher Wert auf die Erstellung von Informationen als auf die Produktivität von Land oder Kapital. Man zieht eine relativistische Weltanschauung einer festgelegten Religion oder Ideologie vor, die wiederum Pluralismus und sich ändernde soziale Rahmenbedingungen fördert. Gleichzeitig wird die Suche nach der Wahrheit nicht länger als oberstes Ziel im Leben angesehen und der Besitz von Bildungsnachweisen ist nicht länger eine Garantie für ein gutes Leben. Bildungsinstitutionen funktionieren nicht mehr, weil sie in ihren Zielen, Aktivitäten, Strukturen, Methoden und Wahrnehmungen ihrer Zielen, Aktivitäten, Strukturen, Methoden und Wahrnehmungen ihrer Zielgruppen mit unzeitgemäßen Normen verknüpft sind. Mittels eines weitreichenden überblicks über jüngste Debatten über Konzepte und die Einschätzung sozialer Trends, untersucht der Artikel die Auswirkungen radikaler zeitgenössischer Anderungen der Normen; die Suche nach einem neuen Paradigma der Bildung hat gerade erst begonnen.
Resumen Hay una percepción general de que el funcionamiento del sistema de educación es deficiente, y este trabajo sostiene que, efectivamente, se produce una profunda crisis causada por la brecha existente entre el sistema y el mundo cambiante que lo rodea. Las condiciones postmodernistas ponen énfasis en la producción de informaciones más que en la productividad de la tierra o del capital, y en una óptica del mundo relativista más que en la adhesión a una religión o ideología fija, lo que por su parte da origen al pluralismo y a sistemas sociales cambiantes. Al mismo tiempo, la busca de la Verdad ya no es considerada como la meta más importante en la vida, y la titularidad de pruebas de formación ya no garantiza el acceso a la Buena Vida. Las instituciones de la educación muestran una disfunción porque aún se atienen a parámetros obsoletos en cuanto a objetivos, actividades, estructuras, métodos y percepciones de su clientela. A través de una amplia reseña de debates conceptuales recientes y de la valoración de tendencias sociales, el trabajo explora las implicaciones que los cambios radicales contemporáneos tienen en los parámetros; la busca de un nuevo paradigma de educaión solamente acaba de comenzar.
Résumé Le système éducatif a la réputation largement répandue de mal fonctionner, et l'article expose qu'il existe en effet une crise profonde due à l'écart entre le système d'éducation et le monde en évolution qui l'entoure. Les conditions de vie post-modernes font passer au premier plan la production de l'information à la place de la productivité de la terre et du capital, et une vision du monde relativiste remplace l'adhésion à une religion ou une idéologie fixe, qui à son tour engendre le pluralisme et la modification des structures sociales. Parallèlement, la recherche de la vérité n'est plus le but suprême dans la vie, et la détention d'une preuve d'éducation n'est plus une garantie d'accès à une vie réussie. Le dysfonctionnement des institutions éducatives réside donc dans leur attachement obstiné à des modèles périmés quant à leurs objectifs, leurs activités, leurs structures, leurs méthodes et leur vision de la clientèle. Sur la base d'une vaste étude sur le récent débat conceptuel et une évaluation des tendances sociales, l'article analyse les conséquences des changements radicaux contemporains sur ces modèles: la recherche d'un nouveau type d'éducation ne fait que commencer.

Educational provision in Kurdistan (embracing parts of Iran, Iraq, Syria and Turkey) violates most of the language-in-education requirements of international law. The same is true for Kurds in diaspora in most parts of the world. Linguistic and cultural genocide is attempted, with the tacit complicity of the West. The future of Kurdish education depends to a large extent on the political situation in the Middle East. Political solutions are needed before educational problems can be tackled. Within international law, a new interpretation by the UN Human Rights Committee of Article 27 in the International Convenant on Civil and Political Rights (UN 1986) might give grounds for hope for the future.
Zusammenfassung Bildungsmöglichkeiten in Kurdistan (einschließlich Teilen Irans, Iraks, Syriens und der Türkei) entsprechen nicht den internationalen Forderungen zur Sprachpolitik in der Bildung. Das gleiche gilt für Diaspora Kurden in den meisten Teilen der Welt. Mit stillschweigender Übereinkunft des Westen wird der linguistische und kulturelle Massenmord angestrebt. Die Zukunft der kurdischen Bildung hängt größtenteils von der politischen Situation im mittleren Osten ab. Bevor jedoch das Bildungsproblem gelöst werden kann, braucht man politische Lösungen. Innerhalb des internationalen Gesetzes könnte eine neue Auslegung des Artikel 27 im Internationalen Convent über zivile und politische Rechte (UN 1968) durch das Menschenrechtskommittee der Vereinten Nationen Hoffnung für die Zukunft bringen.
Resumen La educación prestada en Kurdistán (que comprende partes de Irán, Iraq, Siria y Turquía) viola la mayor parte de las exigencias que el derecho internacional establece en cuanto a la educación en la lengua correspondiente del individuo. Esto también rige para los kurdos, que se encuentran en la diáspora, en muchas partes del mundo. Con ello se intenta un genocidio cultural, con la complicidad tácita del mundo occidental. El futuro de la educación kurda depende en gran medida de la situación política de Oriente Medio. Se requieren soluciones políticas que permitan abordar los problemas de la educación, Dentro del derecho internacional, puede dar lugar a esperanzas una nueva interpretación que el Comité de Derechos Ilumanos de las Naciones Unidas hizo del artículo 27 en el Convenio Internacional de Derechos Civiles y Políticos (UN 1986).
Résumé Les formes d'enseignement dispensé au Kurdistan (partagé entre l'Iran, l'Iraq, la Syrie et al Turquie) violent la plupart des exigences envers les langues dans l'enseignement établies par le droit international. La même constatation est valable pour la diaspora kurde disséminée sur la quasi-totalité de la planète. Il ya a en fait tentative de génocide linguistique et culturel, avec la complicité tacite de l'Occident. L'avenir de l'éducation kurde dépendant dans une large mesure de la situation politique au Moyen-Orient, les problèmes pédagogiques ne peuvent être abordés que si la situation politique est résolue. Dans le adre du droit international, une nouvelle interprétation de l'article 27 de la Convention internationale des droits civils et politiques par le Comité des droits de l'hommes (ONU 1986) pourrait donner un nouvel espoir pour l'avenir.

Large scale computer-assisted instruction systems generally impose severe constraints upon the demands that individual users may make. Nevertheless, it is possible to overcome these problems and a program is described which teaches students how to fly a specific maneuver through real-time simulation of the flight of a student-controlled airplane. This is achieved in spite of the fact that the student is flying his plane through the use of a manually controlled analog input device. Both computational and educational implications are discussed.Contractual support for this work was provided in part by the Life Sciences Program Air Force Office of Scientific Research, Contract number F44620-70-C-0105.

A favorite book of Julia, age three, wasThe Little Engine That Could. When her teacher asked her if she could eat nicely with the class next door, she replied, I think I can, I think I can. As Jenny tramped across a bridge on a bike, she called to her mom, Hey, mom, trip trap trip trap; I hope there's no ugly troll down there. One of her favorite bedtime stories at age four was The Three Billy Goats Gruff.Sharen Halsall is an Assistant Professor in Child Development at Santa Fe Community College, Gainesville, FL.

The goal of this study was to develop a framework for classifying algebra story problems and to determine observed frequencies for each problem type. A total of 1097 algebra story problems were selected from ten standard algebra textbooks. These are divided into eight families based on the nature of the source formula involved; for example, nearly 300 problems were classified in the time rate family because they were based on the source formula, distance = rate x time or output = rate x time. Each family was divided into problem categories based on the general form of the story line; for example, the time rate family consisted of motion, current, and work categories. Each category was divided into templates based on the specific propositional structure of the problem; for example, there were a dozen templates for motion problems such as overtake, closure, round trip, etc. This article describes the procedure for generating families, categories, and templates and provides frequency counts for each observed template. Implications for fostering productive research and instruction are discussed.This research was supported by grant NIE-G-78-0162 from the National Institute of Education.

If Whitehead is right, science teachers who try to increase student interest by making the science they teach more pure and by covering more material are going about their work in just the wrong way. Science, for purposes of precision in measurement, translates the dynamic world of feeling and force, of causal efficacy (for example, the San Francisco earthquake), into a static representation spatialized and given presentational immediacy (for example, the Richter scale). But notice that the Richter scale isn't very interesting (even as abstract art) apart from its connection, via symbolic reference, to the earthquake. Such reference is essential to give both a sense of reality and a feeling of interes to the subject, but it makes the science less pure, and it takes more time to cover the material. An example of teaching pure and impure formal logic is given as a case study.  相似文献

In this note, Blaug's article in Volume 1, No. 1, is criticised on the grounds that the economic interpretation of the correlation between education and earnings is based on a mistaken view about the nature of capital; and hence human capital theories are logically incoherent.  相似文献

Many universities, recognizing the student as the main consumer of college instruction, have begun to seek his views regarding the quality of teaching. In this study the Israeli student's concept of a good teacher has been investigated. A sample of second year university students were asked to select the three most important characteristics of a good teacher from a list of fifteen.It was shown that students attached primary importance to method of instruction. Of secondary importance was the teacher's ability to spark intellectual growth. Research talents, personality, and academic status were of relatively little concern. Social science, life science, law and medical students all concurred in emphasizing the importance of the teacher's ability to communicate ideas, whereas humanities students stressed his ability to stimulate thinking.It appears that undergraduate students rate teachers by their ability to transmit knowledge rather than according to the university's criteria of research and publication.The concepts good teacher and effective instruction are used interchangeably in this article, although they are not identical.  相似文献

Most quality assessment studies utilize a univariate approach to the assessment of quality. While the univariate approach has some merit, this study presents an alternative—the multivariate approach. Factor analysis identified three clusters of variables potentially linked to quality. These clusters, labeled faculty research, input, and student, were later used as bases for measuring departmental excellence. Seven indicators based on these clusters were developed. The indicators that combined the first and second clusters and the indicators that combined all three clusters appeared to have produced the best estimates of departmental excellence.  相似文献

Merker hypothesized that because mobile creatures move around and must constantly readjust their map of the world and because the demands are so great for continually processing information for a map of the world, evolution has created a space in the brain where such preprocessing has been eliminated. This space he calls consciousness with the preprocessing in the unconscious. Using Merker's view, this paper explores the process of changing paradigms, giving advice and the implications for learning.  相似文献

Over the past decade educational reform has been taking place in the USA and in England and Wales. This paper traces the political pressures to change the social subjects curriculum on both sides of the Atlantic. In England and Wales the new National Curriculum aims to raise educational standards and to increase accountability through a national assessment system. In the USA the Federal Government has set to work on establishing national goals. There is evidence in both countries that the new curricula are emerging from a political process which imposes content and structures upon teachers with little consultation. The paper concentrates on how the social studies curriculum has been affected in this process. It explores the politics of curricular reform by comparing events in the USA and England and Wales and outlines the ways, particularly in the British context, in which the teaching profession has explored the limits of its power and has fought back against central control to make its voice heard.
Zusammenfassung In den letzten zehn Jahren gab es eine Bildungsreform in den USA, sowie in England und Wales. Dieser Bericht studiert den politischen Druck, der zu einer Änderung des Curriculums in den Sozialfächern auf beiden Seiten des Atlantiks geführt hat. In England und Wales soll das neue nationale Curriculum den Bildungsstandard anheben und die Verantwortlichkeit durch ein nationales Bewertungssystem steigern. In den USA begann die Bundesregierung mit der Festsetzung nationaler Ziele, die den Lehrern Inhalte und Strukturen mit wenig Mitbestimmungsrecht auferlegt. Der Artikel konzentriert sich auf die Auswirkungen dieses Prozesses auf das Curriculum der Sozialstudien. Er untersucht die Politik der Curriculums-Reform, in dem Ereignisse in den USA, England und Wales verglichen werden. Insbesondere im britischen Kontext werden Wege aufgezeigt, auf denen der Lehrberuf die Grenzen seiner Macht erforscht und sich gegen eine zentrale Kontrolle gewehrt hat, um Aufmerksamkeit auf sich zu ziehen.
Resumen Durante la última década se ha realizado una reforma de la educación en los EEUU, Inglaterra y Gales. Este trabajo esboza las presiones políticas de cambiar los planes de estudio de los sujetos sociales a ambos lados de Atlántico. En Inglaterra y Gales, elNew National Curriculum aspira a crear estándares de la educación y a incrementar la responsabilidad a través de un sistema nacional de valoración. En los EEUU, el Gobierno Federal ha comenzado a trabajar en la fijación de objetivos nacionales. Es evidente que en ambos países los nuevos planes de estudios están emergiendo de un proceso político que impone contenidos y estructuras a los maestros, consultándolos poco o nada. El trabajo se concentra en el impacto que ha sufrido el curriculo de estudios sociales en este proceso. Explora la política de la reforma curricular comparando acontecimientos de los EE UU y de Inglaterra y Gales y proporciona una idea general de los modos, particularmente en el contexto británico, en los que la profesión de enseñanza ha explorado los límites du su poder y se ha defendido contra el control central para hacerse escuchar.
Résumé Au cours de la dernière décennie, une réforme éducative a été engagée aux Etats-Unis, en Angleterre et au pays de Galles. Cet article retrace les pressions politigues qui ont été exercées pour remanier les thèmes sociaux dans les programmes des deux côtés de l'Atlantique. En Angleterre et au pays de Galles, le nouveau curriculum national a pour but d'élever les niveaux de l'enseignement et d'augmenter la responsabilité par un système national d'évaluation. Aux Etats-Unis, le gouvernement fédéral a entrepris d'établir des objectifs nationaux. Il est évident que dans les deux pays, les nouveaux programmes sont nés d'un processus politique qui a imposé aux enseignants des contenus et des structures en les consultant à peine. L'article se concentre sur les retombées de ce processus sur les programmes d'études sociales. Il étudie la politique de la réforme curriculaire en comparant les événements intervenus aux Etats-Unis et en Angleterre-pays de Galles et souligne, en particulier dans le contexte britannique, la façon dont le corps enseignant a épuisé les limites de son pouvoir et a résisté au contrôle central pour se faire entendre.

The ethnomethodological programme of studies of work is drawn on to provide a general framework within which we might develop ways to undertake thein situ analysis of the competencies which constitute student learning activities. The objective of such research is to describe the locally managed and temporally organised nature of student learning work. Emphasis is placed on the development of methods of investigation which will enable us to describe the whatness of the work from within the setting of that work's accomplishment. The twin conceptions of the visibility and sequential order of student activities are discussed in detail. The implications of this approach for the notion of student learning are also examined.  相似文献

Education and the Contested Meanings of ‘Global Citizenship’   总被引：1，自引：0，他引：1  
This article examines the oftentaken-for-granted educational policy and curricular discourses of globalization and global citizenship within their larger cultural, political, and economically uneven histories and unequal consequences. Drawing upon evidence from recent scholarship on the implications for classroom pedagogy embodied inefforts to internationalize curricula in the North American university contexts, as well as specific related efforts in one Canadian context, the University of British Columbia,this article unpacks the contested meanings of global citizenship from above and below.The author analyzes three dominant curricular discourses of global citizenship. Far from weakening the Canadian state and building instances of transnational democratic educational communities, these dominant discourses may actually reinforce notions of Canadian gendered and racialized nation-building and nationalism. The article raises questions about what an alternative curricular and educational policy discourse from below premised upon efforts to decolonize curricula might look like. By way of provisional conclusion, the author discusses some promising examples of such an alternative,showing how they depend on seeing the relations between the local and global neither as fixed abstractions nor as a slogan system to be applied in absolutist racial, geographical,national, or culturally essentialist terms.  相似文献

In the United States, kindergarten marks the beginning of formal schooling for more than 3 million children each year (Shepard & Smith, 1986). At the end of the kindergarten year, most of these children demonstrate expected levels of achievement and are promoted to traditional first-grade classrooms. Others are labeled unready or immature for successful performance in today's academically rigorous first grade. In most elementary schools, the placement for these at-risk children is either retention in kindergarten or social promotion to first grade. An alternative in approximately 17% of the nation's elementary schools is assignment to a transitional classroom between kindergarten and first grade (Educational Research Service, in press). This additional year of instruction is often viewed as a gift of time — time for children to mature and make a gradual transition from kindergarten to first grade.Judith E.

In our current quest for excellence, we often miss the essential nature of it. It is trendy to use such terms as back-to-basics, gifted education, and excellence to describe a new teaching strategy or innovative educational program. It is also true that many of these programs designed for children are really intended to benefit others.Harry Morgan is Chairman of Early Childhood Education at West Georgia College in Carrollton.

Drawing on John Milton's Paradise Lost and on motifs found within Gnostic mythology and the poetry of William Blake, this article explores Philip Pullman's reworking of the Judeo-Christian myth of the Fall. At the centre of this investigation is Dust: a conventional metaphor for human physicality inspired by God's judgment on humanity. This article suggests that Dust is re-presented in the trilogy in a more positive manner through the development of Milton's metaphor of the dark materials into a substance in which good and evil, and spirit and matter—conceptual opposites that form the basis of religious dualism—coexist.  相似文献
