The two concepts law and theory are among the most important elements of the nature of science. They represent both the tools and products of science itself. Unfortunately, the variable meanings and use of these terms in general discourse and in other school disciplines results in much confusion with respect to their proper application in a science context. The project included the design of a six-part model definition for law and theory based on a review of the literature of the philosophy of science with special reference to biology. These model definitions were then compared with those provided in a range of U.S. secondary school biology textbooks. The majority of all current major U.S. secondary school biology texts were reviewed and analyzed with respect to how the concepts of law and theory were defined and applied, in an attempt to determine whether students and teachers using such texts would gain an accurate impression of these terms and the distinction between them. This study focuses on biology instruction since a life science course is completed as a graduation requirement by virtually all U.S. high school students and as such serves as a widely shared educational experience across the nation. The term law is rarely defined in any text but various laws such as those found in genetics are frequently included as examples. The term theory is frequently defined but with a wide range of completeness of the definitions. Only rarely are theories in biology included as examples.  相似文献

Conclusion This historical survey of the educational goals developed on behalf of the immigrant and refugee in America indicates that there has been a complete cycle. The first systematic educational efforts, as we have shown, were aimed at teaching the immigrant the English language so that he would be useful for his tasks in American industry. Then came the period which extended this educational goal by offering instruction in several aspects of acculturation (officially, assimilation, but a concept which has never been put into effect in the history of America's minorities). The post-war period saw the stress on the academic level on the cultural democracy concept; but this ideal has been more academic than practical, and World War II saw no definite evidences of the popular interest in any Americanization program. The recent waves of refugees, bringing in more or less well-educatedindividuals, saw a revival of educational efforts on their behalf; but they differ from the former endeavors in their emphasis on individual education and on instruction in English. The social aspects of acculturation — featuring, in general, the period between World War I and II — have been entirely ignored 1).  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

Many traditional faculty now find themselves working with nontraditional students. New faculty models such as mentoring have emerged in response to the new student. The purpose of this study was to examine the mentoring role at Empire State College, State University of New York, on the basis of mentors' behavior responses to mentor-defined problems. The Critical Incident Technique was the method used to elicit reported and recalled incidents which either facilitated or impeded mentoring. Significant problems cited in the findings included communications gap in mentor/student relationship and the student's incompletion of academic work. Typical corresponding responses to such problems included providing support, demythologizing the learning process, setting behavior limits, and assessing and reassessing student performance. On the other hand, the critical requirements which were inductively derived from the critical incidents, as well as the practical implications which were gleaned from the study, revealed a definite extension of the traditional faculty role.The original document from which this article was adapted, including an extensive bibliography is on file with University of Microfilms International, Ann Arbor Michigan, 48108.  相似文献

This study explores the impact of higher education on 3,942 arts and sciences students as measured by change in their freshman and senior ratings of four Clark-Trow educational philosophies: vocational, academic, collegiate, and nonconformist (Clark and Trow, 1966). A repeated measures analysis of variance was applied to each of the four philosophies, controlling for sex, entering year, major, parents' educational background, scholastic aptitude, and academic motivation. As expected from Clark-Trow theory, students showed significant increases in academic and nonconformist philosophies, and decreases in vocational and collegiate philosophies. Relationships between independent variables and freshman-senior change suggested post hoc reinterpretation of the dimensions underlying the Clark-Trow phenotypes: i.e., from identification with the college and involvement with ideas to social interests and academic interests (the latter suggested by Terenzini and Pascarella, 1977).  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

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

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

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

The thesis of this paper is that it is a productive venture to introduce preservice students to social theories that are typically not a part of teacher preparation programs. Examples of these theories are those associated with terms such as habitus, the carnivalesque, power / knowledge, seduction, detournement, the spectacle,la perruque, (the wig), and the art of making do,as well as others. In this paper, I describe a project that involved exploring the theory of habitus to problematize the tendency of preservice students to not think in terms of relations between what goes on in the classroom and what goes on in society. I introduced habitus by having preservice students read selected print materials and by having them view, analyze, and respond in writing to popular school films. Students also analyzed their experiences in classrooms in terms of habitus, making a connection between theory and practice.  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.

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.

In this note, I argue that the distinction between what one says and what one means by it is no more problematic (and no less) than the equally important distinction between evidence and theory. Both, I suggest, take a particular form in literate discourse.  相似文献

The article reviews the strikingly divergent viewpoints of intellectuals—scientists and non-scientists—about Science and Technology. It shows that while scientists implicitly accept the difference between Science and Technology, to non-scientists that difference is irrelevant. The most important differences between Science and Technology that lie in their relative scales, outputs and accuracy of predictions are highlighted. The complexity of and difficulty in trying to quantify the contribution of science and technology to economic growth are discussed. Views of science and technology that include their societal perceptions are recommended.  相似文献

Children use mathematical terminology throughout their daily play. While observing a group of children during play, one is likely to hear comments such as: He has more, These are my numbers, Jane has the biggest half, I'm bigger than you 'cause I'm five years old, Give me the round one, I gave each child one cupcake, and so on.Diane M.

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

This paper explores the contrasts dividing the excellence and choice movements to date. The orientations of both are examined, along with key features and impacts of each. Particular attention is given the predicament and the challenge of at risk youngsters. Yet there are developments suggesting a growing mutuality between the two movements. The elaboration of a conception of Excellence that makes educational sense reveals the centrality of motivation to educational accomplishment. This in turn exposes the choice principle as an important aid to the pursuit of excellence.  相似文献
