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

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

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

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

Three teaching designs are offered. They were developed for 12 to 16 year old pupils taking into account their personal differences in terms of gender (in Making Up the Cube), culture (in Mecca), knowledge, and use of calculators in The integrating calculator. The designs concern the representation of three-dimensional objects in the plane, directions and great circles on the sphere, and exploration of the integrating calculator.  相似文献

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.

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 paper analyzes the relationship between the epistemological nature of mathematical knowledge and its socially constituted meaning in classroom interaction. Epistemological investigation of basic concepts of elementary probability reveals the theoretical nature of mathematical concepts: The meaning of concepts cannot be deduced from more basic concepts; meaning depends in a self-referent manner on the concept itself. The self-referent nature of mathematical knowledge is in conflict with the linear procedures of teaching. The micro-analysis of a short teaching episode on the concept of chance illustrates this conflict. The interaction between teacher and students in everyday teaching produces a school-specific understanding of the epistemological status of mathematical concepts: the concept of chance is conceived of as a concrete generalization, which takes chance as a fixed and universalised pattern of explanation instead of unfolding potential and variable conceptual relations of chance or randomness and developing the theoretical nature of this concept in an appropriate way for students' comprehension.  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

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

Conventional instruction in critical thinking technique tends to conflate logical thinking with rational or good thinking. But in doing so, it ignores the creative and intuitive functions of rationality, thereby encouraging a mechanically rote approach to textual analysis, problem solving and problem construction. This overemphasis upon straightforwardly logical calculus of justification functions, and its concomitant deemphasis of intuitive pattern of discovery ones, constitute the Spock Fallacy. Its epistemological weakness and pedagogical hazards are explored.The author of two books and numerous articles, one of his specialties is philosophy of education and critical thinking.  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

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

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

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

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

Two Grade 10 classes in an urban Jamaican High School were taught over a period of one academic year in two problem solving styles: an Explicit Style derived from Charles, and an Implicit Style derived from Isaacs. At the end of the academic year there was no significant difference in their performance on a problem solving test, or on the Problem Solving Profile of the Caribbean Examinations Council's Basic Proficiency papers. The two classes performed much better than the population who sat the Basic papers on the tasks measuring Recall and Algorithmic Thinking but only moderately better than the population on tasks measuring Problem Solving.The teaching project described in this paper was supported in part by grants from the Research and Publications Fund Committee of the University of the West Indies (Mona), and the Wolmers Trust, Kingston. The author wishes to thank the Registrar and the Pro-Registrar of the Caribbean Examinations Council for permission to use the CXC papers and data in this study. A modified version of this paper was presented at the 63rd Annual Conference of the National Council of Teachers of Mathematics held in San Antonio, Texas in 1985.  相似文献

The Repertory Grid technique was used to explore differences in the way in which freshers and postgraduate counselling students perceived the roles of counsellor and friend. Postgraduates viewed counsellors as more approachable than other students, while freshers viewed other students as more approachable than counsellors. The constructs identified by the students were content-analyzed to define approachability for each group. The perceptions held by students were used to address implications for the provision of outreach services, role-induction programmes, and the status of the counsellor as the professional.Department of Counseling and Educational Psychology, New Mexico State UniversityFor information contact Peggy Kaczmarek, Ph.D., New Mexico State University, Box 3CEP, Las Cruces, New Mexico 88003, United States.  相似文献

Ogbu  John U. 《The Urban Review》2004,36(1):1-35
After more than 15 years of comparative study of minority education, I concluded that I would have to study two additional factors, namely collective identity and cultural frame of reference to more fully explain the variability in minority school performance. In 1986, I published an article with Signithia Fordham on how oppositional collective identity and cultural frame of reference or oppositional culture contributed to Black students' school performance. Many critics have misinterpreted the joint article and even constructed a different thesis of oppositional culture than the one we proposed in the joint article. The thesis is that Black students do not aspire to or strive to get good grades because it is perceived as acting White. Furthermore, they have translated my cultural–ecological theory into an oppositional culture theory. I am writing this paper to correct the misinterpretations of the joint article in order to advance scholarship on the subject. I begin by explaining the meaning of collective identity and distinguishing it from other concepts of identity. Specifically, I summarize the evolution of oppositional collective identity and cultural frame of reference or oppositional culture among Black Americans and discuss the Black experience with the burden of acting White in the contemporary United States. Finally, I suggest some continuity between Black historical and community experiences with the burden of acting White, as experienced by Black students.  相似文献
