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.

A review of some contemporary studies based on an individual-difference model of student learning is presented. The exploratory fitting of conceptual models of student learning to atypical individual-similarity data structures is discussed, and an experimental categorisation procedure for producing such structures is outlined. Insofar as the features of some established conceptual models of student learning do not fit such atypical structures, either by virtue of their conceptual parsimony, or their underlying conceptual assumptions, the fitting of a locus model to such structures is explored. It is argued that, within the student experience of learning framework, conceptual models of student learning need to incorporate such additional dimensions of variation if such models are to be employed in individual-difference studies of student learning.  相似文献

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

In spite of advances in course design software and experience with online offerings, the question of how web-based education affects teaching and learning remains largely unanswered, and the terrain of online learning remains largely unmapped. In this paper, through the stories of 10 faculties of education and one computer science instructor in Ontario, we map out a small piece of the frontier of web-based course delivery and plot a course for future exploration. We argue that most existing offerings take the form of a Lone Ranger or Greenhorn approach but that there is a need to move toward a strategic institutional Wagon Train approach that consolidates and integrates support for online teaching and learning. We argue, as well, that failures in online instruction cannot simply be attributed to improper instruction or inappropriate course design. Rather, at least part of the problem locates in the ways in which conversation is structured in the online environment.  相似文献

There has been considerable scholarly interest in issues related to gender in the classroom, especially in terms of finding ways in which classrooms might be configured to be more welcoming--and less chilly--to female students. There is some evidence to suggest that the online learning environment may provide educators with opportunities to achieve a more female-friendly classroom, and this study was designed to gather information about that question. 125 female college students who had completed at least one online, college-level class were invited to discuss their experiences learning online. These data show that female college students respond to the online environment in a variety of ways. A small group of students indicated that they did not enjoy learning online, while others expressed mixed feelings. The majority, however, had positive things to say about their online classroom experiences; and of these, a large number identified anonymity as the most important positive aspect of the online learning environment.  相似文献

Not only are school-age ethnic and racial minority children one of the fastest growing segments of the U.S. population, they are also one of the most vulnerable. Hispanic children in particular are representative of the at-risk status of minority populations, displaying a portrait of unrealized social, educational, and employment success. This paper addresses the background and history of U.S. social and educational policies as they relate to the Hispanic student. Recent empirical findings are presented which support the following: (a) the bilingual character of Hispanic children is not a linguistic, cognitive, or educational liability and, in fact, should be employed to promote academic achievement; (b) the culture of the Hispanic family and child are better understood with regard to socialization variables and the potential differences they produce when directly compared to Anglo culture; and (c) educational strategies for Hispanic students that respect and integrate students' social, psychological, and linguistic attributes serve students effectively.  相似文献

There are cases in which a high form of a language is taught and used in formal situations, but linguistic variation is also caused by geography, ethnicity and socioeconomic class. Certain variants are regarded as inferior and restricted in expressive capacity, and are disadvantageous. The paper suggests that it is possible to map each person's linguistic identity in two dimensions: the number of languages spoken, and the situation-specific variants of each language. Further, it is argued that the distance between a low variant and a high standard form of a language may present to the low learner of a standardized mother tongue a barrier just as great as that posed by the learning of a related foreign language to a speaker of the high variant. It is proposed that greater tolerance be exercised in acceptance of variation and in recognition of linguistic identity, so that this can be built on in the necessary and desirable expansion of linguistic competence, rather than being devalued. The relevance of the communicative approach to language teaching is touched on.
Zusammenfassung Es gibt Fälle, in denen eine hohe Form einer Sprache gelehrt und in formellen Situationen gebraucht wird, aber linguistische Veränderungen werden auch durch Geographie, ethnische Identität und sozialkonomische Klassen hervorgerufen. Gewsse Varianten gelten hinsichtlich ihres Ausdrucksvermögens als unterlegen und restriktiv und sind unvorteilhaft. In dem Artikel wird vorgeschlagen, die linguistische Identität jedes Einzelnen in zwei Dimensionen darzustellen: die Anzahl der gesprochenen Sprachen und die situationsspezifische Variante jeder Sprache. Weiterhin wird argumentiert, daß die Distanz zwischen einer niedrigen Variante und einer hohen Standardform einer Sprache für den niedrigen Lernenden einer standardisierten Muttersprache ebenso schwierig ist wie das Erlernen einer verwandten ausländischen Sprache für denjenigen, der die hohe Form spricht. Es wird vorgeschlagen, größere Toleranz durch Akzeptieren der Variation und Anerkennung der linguistischen Identität zu üben, so daß man darauf die notwendige und wünschenswerte Erweiterung der linguistischen Fähigkeit aufbauen kann anstatt sie zu entwerten. Die Relevanz des kommunikativen Ansatzes zum Unterrichten einer Sprache wird kurz behandelt.

Résumé Il existe des cas où une haute forme d'une langue est enseignée et utilisée dans des situations formelles, mais la différentiation est causée également par la géographie, l'ethnicité et la classe socioéconomique. Certaines variantes sont considérées inférieures, d'une capacité expressive limitée, et sont désavantageuses. L'article suggère qu'il est possible de tracer l'identité linguistique de chacun dans deux dimensions: le nombre de langues parlées, et les variantes de chaque langue reliées à des situations spécifiques. En plus, on raisonne que la distance entre une variante basse d'une langue et la haute forme standard peut présenter à l'apprenant, ayant la forme basse d'une langue maternelle standardisée, une barrière aussi grande que celle qui se dresse devant celui qui parle la variante haute et qui apprend une langue étrangère apparentée. On propose donc qu'une tolérance plus large soit exercée en acceptant la variation et en reconnaissant l'identité linguistique, afin que cette dernière serve de fondation pour l'élargissement nécessaire et souhaitable des compétences linguistiques, plutôt que d'être dévalorisée. La relevance de l'approche communicative à l'enseignement des langues est mentionnée.

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.

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

This research links two important higher education phenomena: potential brain drain among academics abroad and the U.S. academic labor market. The inquiry draws on the brain drain literature and is grounded primarily on a secondary analysis of a major survey (1989) of British university and polytechnic faculty members. The anlaysis shows that fully 40.0 percent of university faculty are seriously considering a move abroad with the substantial majority favoring the United States as a destination. Faculty characteristics—including academic field, research versus teaching orientation, rank, age, gender, and political identification—are correlated with faculty members' professed interest in emigration. The analysis also compares (former) polytechnic to university faculty as well as to a subset of Oxford and Cambridge faculty.  相似文献

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

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

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

Visual media of communication are not just convenient and indifferent technologies for the transmission of knowledge but also, and perhaps mainly, different languages for gathering, packaging and conveying knowledge. The real differences among the media are not so much in the kinds of knowledge they can convey, but rather in the languages, that is — the symbol systems — they uniquely employ. The experienced horrors of Clockwork Orange, or the possible better understanding of group processes after viewing Twelve Angry Men are greatly due to the visual mode and the unique languages of such films, not just the content (which can be read in a book).Media's different and often unique symbol systems have been studied in recent years. It has been found, for example, that different symbol systems call upon different kinds of mental skills and convey different meanings. But above all, media's unique symbol systems cultivate unique mental skills by either activating or overtly supplanting them. By doing so, these symbol systems offer new ways for internal, cognitive, representation. Thus, they can be seen as potentially serving as cultivators of mental abilities.This paper was presented at the IW APP Festival 1980, Amsterdam, The Netherlands, January 1980.  相似文献

The Total Quality Initiative at South Bank University   总被引:2,自引:0,他引:2  
The total quality initiative covers all aspects of the University's academic and support services, but only one of a number of different programmes is discussed in detail, the formulation of quality service agreements. The paper outlines both the theoretical basis and the practical implementation of the approach. Another programme, quality in teaching and learning, is also briefly outlined.The systematic examination and articulation of customer/supplier relationships lies at the core of South Bank's total quality approach, with quality being customer rather than system driven. The concept of the quality chain is developed to stress and demonstrate the interdependence of all staff in providing a high quality service to students.The customer/supplier relationship is founded on three aspects of quality-characteristics, standards and measurement of performance, all of which are dealt with in some detail.Thirty-two Customer/Supplier Working Groups are charged with the task of establishing detailed quality service agreements between academic schools and support departments the internal customers and suppliers, and between the schools as suppliers and their students (and other clients) as external customers.  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

Community financing is an important source of supplementary funds for education, particularly where governments are unable to meet all the needs of their peoples. While this is widely recognised, little empirical research has been conducted on the topic. This paper analyses patterns in Bhutan. It observes that until the 1990s few resources for education were provided by communities, but that the scale of financing has increased during the present decade. The paper notes that although communities have in general responded positively to government calls for local inputs, local resourcing has some problematic aspects. The paper focuses particularly on issues of regional, rural/urban and socio-economic equity, and shows how discussion of Bhutanese experiences contributes to the international literature.
Zusammenfassung Finanzierungen über die Gemeinde sind eine wichtige Quelle der Bezuschussung von Bildung, besonders dort, wo Regierungen nicht in der Lage sind, den Bedürfnissen der Bevölkerung gerecht zu werden. Obwohl dies weitreichend bekannt ist, gibt es kaum empirische Studien zu diesem Thema. Dieser Artikel befaßt sich mit der Situation in Bhutan. Es wird festgestellt, daß die Gemeinden bis zu den 90ern kaum Gelder für die Bildung zur Verfügung stellten, daß aber der Rahmen der Finanzierung in diesem Jahrzehnt gestiegen ist. Der Autor beschreibt, daß trotz einer allgemein positiven Antwort seitens der Gemeinden auf Forderungen der Regierung nach lokalen Finanzbeiträgen, Probleme hinsichtlich lokaler Finanzierungen bestehen. Insbesondere befaßt sich der Artikel mit Themen über regionale, ländliche und städtische und sozialökonomische Gleichheit und zeigt, wie die Diskussion über die Erfahrungen in Bhutan zur internationalen Literatur beiträgt.

Resumen La financiación a través de la comunidad es una fuente importante de recursos adicionales para la educación, particularmente allí donde los gobiernos son incapaces de satisfacer todas las necesidades de sus habitantes. Si bien este es un hecho ampliamente conocido, existen muy pocos estudios empíricos sobre este tema. El trabajo analiza los modelos existentes en Bhután y observa que hasta los años noventa, eran pocos los recursos financieros provistos por las comunidades, mientras que durante la década actual han aumentado estos niveles de financiación. El estudio observa que, a pesar de que las comunidades, en general, han respondido de forma positiva a las llamadas del gobierno a realizar inversiones locales, la creación de recursos locales tiene algunos aspectos problemáticos. El trabajo se concentra particularmente en problemas de equidad regional, rural/urbana y socioeconómica, demostrando cómo la discusión sobre experiencias bhutanesas presta su aporte a la literatura internacional.

Résumé Le financement communautaire représente une source importante de fonds supplémentaires pour l'éducation, en particulier quand le gouvernement ne peut répondre à tous les besoins de la population. Bien que ce fait soit largement reconnu, il n'existe que peu de recherche empirique sur le sujet. Cet article analyse différents modèles existant au Bhoutan. Il constate tout d'abord que jusque dans les années 90, les communautés ne fournissaient qu'une faible partie des ressources de l'éducation, mais que cette forme de financement a augmenté au cours de la dernière décennie. Il relève également qu'en dépit de la réaction généralement positive de la part des communautés envers l'incitation du gouvernement à un financement local, ce modèle présente néanmoins des difficultés. L'article se concentre d'autre part sur les questions d'équitabilité entre régions, entre villes et provinces et entre niveaux socioéconomiques, et révèle que la discussion sur les expériences du Bhoutan contribue à enrichir la littérature internationale.

A SYSTEMIC,STUDENT-CENTERED STUDY OF UNIVERSITY SERVICE   总被引:1,自引:0,他引:1  
This paper discusses the methods and findings ofthe Student Focus Project, a sixmonth study of studentperceptions of service at a large university inBrisbane, Australia. The study paneled 24 focus groups of undergraduate students to assess theirbeliefs about a pretested set of questions concerningpositive and negative aspects of university life,successes and frustrations with university service,attempts to overcome the obstacles of university life,and what students expect from their relationship to theuniversity. Of the themes identified in the StudentFocus study, it was found that malignantbureaucracy and the balkanization ofInformation are systemic factors that negativelyinfluence student perceptions of the quality ofuniversity service. It was also found that studentstrategies for service recovery can contribute to the overall confusion andpoor performance of university services.  相似文献

Summary In sum, through our projects these two students, the other 17 students, and myself, were making sociology of education relevant to our emerging personhood — to the person we are always becoming. It became less an abstract course title and more something we engaged in as part and parcel of our lives. In effect, we were beginning to develop a more community-oriented education by attempting to overcome what Jim Harding (1978, pp. 287–289) has characterized as the self-defeating polarizations of form and content of learning, of theory and practice, of political and personal matters.For me, there is no turning back. I do not think I'll ever again feel comfortable in a learning environment that is not moving toward the less-structured end of the continuum. Such an environment will not eliminate the hidden curriculum of institutional sexism, racism, and class bias which permeates this society and its schools at all levels. But as the data from this research indicate, constructing such an environment in your own classroom can make a difference — can be a long beginning step toward bringing inequities grounded in gender, ethnic, and socio-economic differences out of hiding. Then, and only then, can people openly acknowledge these differences and work on keeping some of the most destructive consequences that flow from them from being transmitted as miseducation from generation to generation.  相似文献
