This case study of a midwestern school districts reform effort explored the treatment fidelity of the Science: Parents, Activities, and Literature (Science PALs) project. Data were collected from the perspectives of three stakeholders: students, school district, and parents. Students and school district supervisors perceptions indicated that teachers were implementing predicted curricular and instructional features promoted by the Science PALs project. Students perceptions of their current teachers classroom performance did not parallel the supervisors perceptions of the teachers implementation. Parents perceptions and comments indicated a high level of satisfaction with the implemented features. Collectively, the three perspectives suggest that the Science PALs project was successful in changing the classroom practices of K–6 teachers involved in the professional development. The results of this study appear to support the findings of other recent studies that indicate the need for extended professional development and support to fully implement changes in elementary school science instruction. 相似文献

Orson Scott Cards school stories in outer space, Enders Game and Enders Shadow, purportedly occur at the same time and tell the same story, but from the perspectives of two different child protagonists. Scenes in Enders Shadow even reproduce text from Enders Game. Nevertheless, 14 years elapsed between the publications of the two books. This essay brings child studies and exceptionality research to bear on the two novels, analyzing the development of Cards ideology regarding his view of the exceptional child and his view of the nature of heroism in a post-modern world. 相似文献

This study explores the use of Valsiners zone theory as a way to interpret the zones of proximal development of three secondary teachers in mathematics and science. Specifically, we used classroom discourse to identify what the participating teachers promoted (zone of promoted action) or allowed (zone of free movement) in the classroom as a way to understand better their potential for development. We found that teachers who promoted actions or events that they ultimately did not allow students to experience seemed to be at a point in their development analogous to Vygotskys pseudo-conceptual stage, prior to full concept formation. Moreover, we found that, at this illusionary zone, the teachers capacity to listen actively to students thinking seemed to affect the teachers transition toward more inquiry-based forms of practice. We concluded that understanding the zone of promoted action and the zone of free movement the teacher organizes in the classroom can indicate the existence or absence of an illusionary zone and thereby provide insight into a teachers potential for development. 相似文献

The three main theses proposed by Mario Bunge are discussed. The peculiar nature of quantum discreteness is argued in disagreement with his first one. General agreement, with some important distinctions, is expressed instead with his other two theses about the peculiar nature of the properties of quantum objects, and the realist interpretation of Quantum Theory. The notion of context dependent, but objectively definable, properties, and the redefinition of Natural Laws as general constraints allowing the occurrence of random events not conflicting with them are however needed in order to qualify more precisely the meaning of terms such as properties and realism. A new probabilistic formulation of Quantum Mechanics in phase space, which eliminates, together with the unphysical concept of probability waves, also the main paradoxical features of the conventional theory, is finally briefly sketched. 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 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

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

A Generative-Predicational Model is proposed and applied to the generation of meanings of simple mathematical word-problems. The model suggests that a fundamental property of cognition is a generative process that takes arguments and that produces results, such as events, answers and inferences. This fundamental property, called predication, generates a task-environment i.e., a problem and its corresponding problem-space i.e., its solution. More precisely, a task-environment is a predication consisting of a written mathematical problem and a writer's life experience. A problem-space is a predication consisting of a leamer's problem solving schema and of the meaning that the learmer generates for the text.The case with which relations can be established between a task-environment and a problem-space depends on the problem's coherence and complexity and the leamer's experiences and thought processes. Faceted definitions of task-environment and problem-space are used to analyze talk-aloud protocols of fifty Israeli sixth-graders tested with thirty word-problems. The empirical results support the proposed model. 相似文献

Elbers grapples with two persistent issues in psychology: (a) the role of the adult and the child in development, and (b) depictions of competence as context specific or generalized. Elbers' entrenchment in a transmission model of meaning undermines his portrayal of the child as an active participant in development. Furthermore, his characterization of competence as something in the head of the individual hinders his attempts to contextualize competence. We outline a framework informed by Vygotsky, Bakhtin, and others, which depicts both the formation and the functioning of mental processes (or competence) as fundamentally interactive. Mental functions arise in social interactions in which all participants accommodate each other, thus obviating the question of who is active or passive in the interaction. Furthermore, the social interactive origins of mental functioning impose a social context on all competencies. Such a framework facilitates movement away from the dilemmas which Elbers cogently raises. 相似文献

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 suggests a theoretical framework to deal with some well known phenomena in mathematical behavior. Assuming that the notions conceptual and analytical are clear enough in the domain of mathematical thinking, the notions pseudo-conceptual and pseudo-analytical are proposed and explained. Examples from mathematics classrooms, mathematics exams, and homework assignments are analyzed and discussed within the proposed theoretical framework.The notions pseudo-conceptual and pseudo-analytical proposed in this paper, actually narrow the extension of the notion cognitive by restricting it to the domain of meaningful contexts. Analysis of meaningless behaviors, it is claimed, requires a different theoretical framework. The attempt to analyze meaningless behaviors in the same way as meaningful behaviors is called here the cognitive approach fallacy. 相似文献

This paper describes Mr. Collins, a student model for intelligent computer assisted language learning (ICALL), which is based on the results of empirical studies conducted in the target domain. Mr.Collins is constructed and updated through student/system collaboration. This collaborative approach to learner modelling aims both to promote student reflection through discussion of the student-model, and to provide more detailed and accurate information for the model. Due to his own contributions the student is less likely to regard the model with suspicion. Because the student model is the focus of the system, it must contain more information than is typically found in learner models. Therefore, in addition to domain knowledge and misconceptions, Mr. Collins also models learner confidence, background languages and learning strategies. The typical acquisition sequence for the target rules is explicitly modelled to provide an additional perspective from which the system may assess learner input.This is an extended version of a paper presented at PEG93. 相似文献

In the past, it has not been possible to teach oneself to read at home, because learners could not read the books to teach them. Videos and interactive compact discs have changed that situation and challenge current assumptions of the pedagogy of literacy. This article describes an experimental adult literacy project using video technology. The language used is English, but the basic concepts apply to any alphabetic or syllabic writing system. A half-hour cartoon video can help adults and adolescents with learning difficulties. Computer-animated cartoon graphics are attractive to look at, and simplify complex material in a clear, lively way. This video technique is also proving useful for distance learners, children, and learners of English as a second language. Methods and principles are to be extended using interactive compact discs.
Zusammenfassung In der Vergangenheit war es nicht möglich, sich selbst in Heimarbeit lesen beizubringen, da die Lernenden die Lehrbücher nicht lesen konnten. Videos und interaktive Compact discs haben diese Situation geändert und gegenwärtige Meinungen zur Pädagogik der Alphabetisierung herausgefordert. Dieser Artikel beschreibt ein experimentelles Erwachsenenalphabetisierungsprogramm, das Videotechnologie anwendet. Arbeitssprache ist Englisch, aber das Grundkonzept gilt für jedes alphabetische oder syllabische Schreibsystem. Ein halbstündiges Zeichentrickvideo soll Erwachsenen und Jugendlichen mit Lernschwierigkeiten helfen. Computeranimierte Zeichentrickgraphiken sind attraktive Lernmittel, die komplexes Material klar und lebendig vereinfachen. Diese Videotechnik dient auch Fernlerndenden, Kindern und Lernenden mit Englisch als Zweitsprache. Methoden und Prinzipien müssen durch den Gebrauch von interaktiven Compakt Discs erweitert werden.
Resumen Durante el pasado, no ha sido posible el autoaprendizaje de la lectura en el hogar, ya que los lectores no estaban en condiciones de leer los libros de enseñanza. Ahora, los videos y los discos compactos interactivos cambiaron esta situación, creando un desafío para los conceptos corrientes de la pedagogía de alfabetización. Este artículo describe un proyecto experimental de alfabetización de adultos mediante el uso de tecnología de video. El lenguaje utilizado es el inglés, pero los conceptos básicos son aplicables para cualquier sistema de escritura alfabética o silábica. Un video de dibujos animados de media hora de duración puede ayudar a los adultos y adolescentes con dificultades de aprendizaje. Las gráficas animadas por computadora son atractivas para el espectador y simplifican materias complejas de un modo claro y ameno. Esta técnica de video también está mostrando su utilidad para el estudio a distancia, para la instrucción de niños y para el aprendizaje del inglés como segunda lengua. Los métodos y los principios también se pueden ampliar mediante la utilización de discos compactos interactivos.
Résumé Jusqu'à présent, il n'était pas possible d'apprendre à lire seul chez soi, puisque les apprenants ne pouvaient pas lire les manuels d'enseignement. La vidéographie et le disque compact interactif ont modifié cette situation et remettent en cause les principes courants de la pédagogie de l'alphabétisation. L'article décrit un projet expérimental d'alphabétisation des adultes qui exploite la technologie vidéo. La langue utilisée est l'anglais, mais les concepts de base peuvent être appliqués à tout système d'écriture alphabétique ou syllabique. Un dessin animé sur vidéo d'une demi-heure se propose d'aider les adultes et adolescents éprouvant des difficultés. Les graphiques animés par électronique sont agréables à regarder et illustrent de façon claire et vivante les matières complexes. Cette technique vidéo se révèle également utile pour les apprenants à distance, les enfants et pour l'enseignement de l'anglais en seconde langue. Les méthodes et principes d'utilisation de disques compact interactifs restent à développer.

Several conventional spelling sequences for morphemes do not conform to letter-sound correspondence rules. One example is the -ed spelling for the inflectional morpheme at the end of English past verbs. Previous work has shown a close relationship between children's awareness of grammatical distinctions and their success in learning about this spelling sequence. However, this research was with real verbs and the children's spelling might have been influenced by familiarity with the words. To check this, we devised a task with pseudo-verbs. This is a novel use of pseudo-words, which hitherto have been a tool for testing letter-sound knowledge; here the spellings violated letter-sound relationships and followed a morphological pattern. The children heard passages with a pseudo-verb in the past tense and in other tenses and had to write the pseudo-verb in the past tense. The task contained both regular pseudo-verbs, whose stem was the same in the present and past tense, and irregular pseudo-verbs, which had different stems in the present and the past tense. The children's scores in a grammatical awareness task predicted their use of the -ed spelling sequence over a 21 month period. The children also used -ed endings significantly more often in regular than irregular pseudo-verbs. We conclude that the use of -ed endings for regular verbs reflects a morphological spelling strategy based on children's grammatical awareness. 相似文献

Foreign study is a multifaceted phenomenon - its impact is felt on academic institutions in both the host and sending countries, on the economies of nations, and of course on the individuals involved. With more than one million students studying abroad, foreign study has assumed considerable importance in higher education planning. This article considers the many aspects of foreign study and discusses the interrelationships of these elements. The policies of the host nations, for example, have an impact on higher education planning in the sending countries. The non-return of foreign students, traditionally referred to as the brain drain, is considerably more complex than was once thought since Third World graduates settled in the industrialized nations often retain contacts with their home countries and increasingly return after a period abroad. This article also considers the various push and pull factors which determine the constantly changing flow of foreign students.This study was supported by the Organisation for Economic Co-operation and Development, Centre for Educational Research and Innovation. It was presented at the International Seminar on Higher Education and the Flow of Foreign Students, convened by the Hochschul-Informations-System, with support from the Federal Ministry of Education and Science and the Lower Saxony Ministry of Science and Arts in Hannover, Germany on 26th–28th April 1990. 相似文献

Governments in most western countries consult extensively with clientele groups in the process of formulating higher education policy. The nature of these consultative mechanisms, in turn, influences the manner in which decisions are made, and the substance of policy outcomes. This article explores the changing style of government-interest group interaction in Australia over the decade 1985–94 and how these changes have effected the way policy is determined. It is argued that Australia has gone through three phases over that time. Until 1987 policy was formulated by a stable policy community. From 1988–90, when a number of major reforms were introduced, this framework was replaced by a brief period of state direction. During the early 1990s a new environment characterised by unstable issue networks emerged. 相似文献

This paper details the impact of market policies in New Zealand on one low socio-economic school, raising questions about the underlyingassumptions of the programmes designed to turn around so called failing schools. The impact of macro policies on disadvantaged schoolsin the market place is documented, as is recent evidence on the impactof schools entering a spiral of decline on their examination outcomes.It is argued that school success and failure cannot be understood inisolation but needs to be placed in the wider context of stateeducational policy. Consequently, change strategies which ignore thewider policy settings risk failure. 相似文献

The purpose of this paper is to identify the factors that predict students perceptions of their institutions success in achieving a positive climate for diversity. This study examines a sample of 544 students at a large, public, predominantly White Mid-Western institution. Results show that students perceptions of the institutions ability to achieve a positive climate for diversity is a reflection of students precollege interactions with diverse peers and the institutions ability to incorporate diversity-related issues into its curriculum. Results also indicate that these perceptions differ by race and gender. Implications for institutional researchers are discussed. 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.
