This study examined learning in the domain of sentence parsing and syntax tree-diagram construction. The aim of the study was to assess whether subjects could learn vicariously from recordings of interactions between a previous student and a tutor.Four intervention conditions and a control condition were compared. Subjects in a dialogue group (DL) read printed tutorial notes and subsequently vicariously viewed dynamic (animated) recordings of tree diagrams being constructed by a previous student in the presence of a tutor.The discourse (DI) condition was similar except that subjects viewed recordings of tree diagrams being constructed by a tutor who concurrently verbalised instructional discourse.In a third condition (DO), subjects viewed tree-diagram construction animation clips which were not annotated with either dialogue or discourse. In a linear text (LT) condition, subjects were given only printed tutorial notes. A control (CO) condition involved pre and post testing without any intervention.Results indicated that the dialogue condition was as effective as the discourse condition. This provides support for contention that re-usable dialogue is a useful resource for the vicarious learner. Another finding was that un-annotated animated diagrams were surprisingly effective. Several reasons for their effectiveness are suggested from the literature on instructional animations.  相似文献

There is necessarily a loss of information when moving from a geometrical object to its drawing, but pupils (even sixth graders) frequently have the illusion that they can, thanks to a drawing sufficiently sophisticated and close to the object, make a representation of it in which there is no ambiguity at all.Similarly, when reading a drawing, they tend to regard the properties of the drawing as properties of the object itself. To illustrate this knowing vs seeing conflict, two examples, studied in three French sixth classes, are given: one of coding, the other of decoding a drawing. They show clearly that it is necessary, at high school level, to make the rules for drawing space geometrical figures explicit, these rules being not the concern of more or less hazy conventions, but of projective geometrical properties.  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

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

Education for work: Reflections towards a theory of vocational education   总被引:1,自引:0,他引:1  
By integrating aspects of a philosophy of work and a sociology of work, this article draws conclusions relevant to framing a theory of vocational education. Education for work is accepted in this paper as the common central meaning of the term vocational education. The two concepts, education and work, are first examined separately: work is seen to include recreational and occupational work, while occupational work is seen to fall on a continuum ranging from constrained to unconstrained occupational work. Education and training are distinguished. After a discussion of the conceptual links which might be drawn between education and work, recommendations are made about the aims, the place, and the curriculum of vocational education within the general institution of education.
Zusammenfassung Durch die Integration von Aspekten einer Philosophie der Arbeit und einer Soziologie der Arbeit kommt der Verfasser dieses Artikels zu Schlußfolgerungen, die eine Theorie der Berufsbildung entwickeln. Bildung für die Arbeit wird in diesem Artikel als die allgemeine, zentrale Bedeutung des Begriffes Berufsbildung verstanden. Die beiden Begriffe Erziehung, und Arbeit werden zunächst einzeln untersucht: Arbeit umfaßt hier Freizeit- und Berufsarbeit; Berufsarbeit ist ein Kontinuum von mehr oder weniger vorgegebener Tätigkeit. Es wird zwischen Bildung und Ausbildung unterschieden. Im Anschluß an eine Diskussion über begriffliche Gemeinsamkeiten zwischen Erziehung und Arbeit werden Vorschläge über Ziele, Einordnung und Curriculum der Berufsbildung innerhalb des allgemeinen Systems der Erziehung unterbreitet.

Résumé En intégrant des aspects d'une philosophie et d'une sociologie du travail, cet article tire des conclusions pertinentes pour l'élaboration d'une théorie de l'éducation professionnelle. L'éducation pour le travail est prise dans cet article au sens commun central du terme éducation professionnelle. Tout d'abord, on examine séparément les deux concepts éducation et travail: on considère que le travail inclut les occupations récréatives et professionnelles alors que le travail professionnel est vu en tant qu'un continuum allant du travail professionnel contraint au travail non contraint. On distingue l'éducation de la formation. Après une discussion sur les liens conceptuels qui pourraient être établis entre l'éducation et le travail, des recommandations sont faites sur les objectifs, la place et le contenu de l'éducation professionnelle au sein de l'institution générale de l'éducation.

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

Research and scholarship: Perceptions of senior academic administrators   总被引:2,自引:0,他引:2  
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

A recent book by Frank Swetz and others has postulated the existence of the phenomenon socialist mathematics education. In this paper we consider critically Swet's arguments and assertions and suggest an alternative methodology whereby one might attempt to describe socialist mathematics education.  相似文献

It is a main contention of this paper that the history of science is not so much a story of the progressive advance in our understanding and discovery of the facts of nature, but rather, an account of different ways of seeing things; where the things thus seen are to a considerable extent themselves the result of realizational processes operating in terms of some theory or other. But further, such theories are in turn controlled by some respective methodology which has its history: with the latter itself a record of different views about those elements believed to be essential for any adequate constructionof scientific theories. The paper then distinguishes between three views, the rationalist, the empiricist, and the systemic processing of scientific facts; the last-named view operating under the guidance of certain leading maxims and principles. Finally, the paper formulates a triadic type of methodology whose three components mirror the three views just mentioned: the probative, the explicative and the systemic components; which in turn are then shown to generate three corresponding ontologies.  相似文献

An analysis of the contents of nine volumes of the International Journal for the Advancement of Counselling has been attempted in this article. The publications have been organized under fifteen headings. Two topics were analyzed more thoroughly: Theories and models of counselling and Country studies, presented by scholars of the countries studied.  相似文献

Counselling clients who fail to begin counselling or terminate after one session are often labelled failures, dropouts, unmotivated, etc. There is some evidence, however, that such clients cannot be assumed automatically to be failures or unimproved. The present study used a series of self-report questions similar to those reported in Talmon (1990) in a telephone follow-up of no show and one session only clients at a community counselling agency in Christchurch, New Zealand. The aims were to replicate Talmon's research by determining the rates of improvement and the reasons for not commencing or continuing counselling in these two groups of clients. In addition, the reasons for any improvements among clients in both groups were investigated. Results indicated that substantial percentages of both groups reported problem improvement. Reasons for not beginning or continuing in counselling included excessive cost, being waitlisted and practical problems like lack of transportation. Reasons for improvement included efforts at self-improvement and/or having sought counselling elsewhere (no show clients) or having benefitted sufficiently from their single session (one session only clients). Implications for counselling agencies are discussed.Robert Manthei, a Senior Lecturer in Counsellor Education at the University of Canterbury, has been involved in counsellor education in New Zealand for over 20 years.  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

Interest in performance budgeting is growing despite a lack of research on its effectiveness. U.S. states have largely used incremental and formula budgeting processes to fund higher education. However, more than half of them are experimenting with some form of performance budgeting. There have been similar attempts to reform budget practices in the U.S. in the past, but most of these processes have been largely abandoned. Governmental performance budgeting for higher education assumes policy objectives are stable, complex decisions on budget trade-offs can be made at governmental levels on the basis of data, institutions operate as bureaucracies, resources can be linked to outcomes, outcomes are identifiable and can be agreed upon, accountability can be achieved through budget policies, and current practices create incentives to enrol unqualified students. These assumptions are not realistic. Consequently, performance budgeting will not meet proponents expectations and will suffer the fate of past budget fads.  相似文献

In this paper a concept of infinity is described which extrapolates themeasuring properties of number rather thancounting aspects (which lead to cardinal number theory).Infinite measuring numbers are part of a coherent number system extending the real numbers, including both infinitely large and infinitely small quantities. A suitable extension is the superreal number system described here; an alternative extension is the hyperreal number field used in non-standard analysis which is also mentioned.Various theorems are proved in careful detail to illustrate that certain properties of infinity which might be considered false in a cardinal sense are true in a measuring sense. Thus cardinal infinity is now only one of a choice of possible extensions of the number concept to the infinite case. It is therefore inappropriate to judge the correctness of intuitions of infinity within a cardinal framework alone, especially those intuitions which relate to measurement rather than one-one correspondence.The same comments apply in general to the analysis of naive intuitions within an extrapolated formal framework.  相似文献

An earlier research project, the Concepts in Secondary Mathematics and Science (Mathematics) project, identified both a hierarchy of levels of understanding in different areas of secondary mathematics, and a number of particular errors which were made by significant proportions of the children tested. Preliminary consideration of these errors and the strategies which appear to have given rise to them suggests that the use of informal naive methods which are limited in their applicability is widespread even at fourth-year level. The suggestion is made that there may be two systems of mathematics coexisting in the secondary school classroom: the formal taught system, and a system of child-methods which are based upon a counting, adding-on or building-up approach, and by which children attempt to solve mathematical problems within a human-sense framework. The difficulties which some children appear to experience in mathematics is suggested to be due in part to these children's non-initiation into the formal taught system. The implication of such a view for teaching and research are indicated.  相似文献

This paper problematises confidence as a frequently used explanation for performance in the mathematics classroom. I report on an interview-based study of how some English Advanced level (16+) students who have chosen to study mathematics, and their teachers, speak about confidence with respect to the learning of mathematics. I outline what constitutes confident learners for these teachers and, differently, for their students and what the students feel teachers could do to improve the students confident state. I discuss the implications of this for the education of prospective teachers of mathematics.  相似文献

Swedish universities are required to change towards more effective self-regulation as the government has recently reduced state steering and devolved further responsibilities to them. In this paper, self-regulation is related to the concept of autonomy, a concept which is analysed on the two dimensions of purpose and authority, resulting in four models of state governance and consequently in a different space of action for the institutions. However, in order to develop self-regulation, the space granted must also be used effectively to realise autonomy. Six Swedish higher education institutions are analysed concerning how they have used their new space of action and what restrictions they have met in their efforts for self-regulation.  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

Methods developed by Newman and Casey for analyzing errors made by children attempting verbal arithmetic problems are described, with particular emphasis being given to Newman's hierarchy of error causes. Data obtained by Newman, Casey, and Clements are presented. These show that a large proportion of errors made by children in grades 5–7 in Victoria on verbal arithmetic problems are in the Newman categories Comprehension, Transformation, Process Skills, and Carelessness.  相似文献

Despite significant expansion in participation over the last three decades, Austrian higher education has been slow to change either its elitist self-concept or structure. But, as is the case elsewhere, the Austrian academic community is beginning to be confronted with such concepts as efficiency, strategic planning, deregulation, and performance evaluation. Inadequate admission policies, extreme overcrowding, and high dropout rates are but three factors placing pressure on Austrian higher education to reform. The system is not only in need of increased budget allocations, but also requires new policies to guide it into the 21st Century.  相似文献
