Double-coding refers to the simultaneous holding in declarative and procedural memory stores of information concerning the performance of a skill. Skill acquisition typically terminates in a stage of automatization during which declarative coding of skill-relevant information is lost or becomes irretrievable. It is argued that maintenance of both declarative and procedural knowledge relevant to skills and their performance permits unique metacognitive capabilities. It is argued further that these metacognitive capabilities are basic to constructive generation and utilization of such skill-relevant knowledge. Speculation is entertained concerning instructional means of helping learners to maintain double-coding of skill-relevant information, thus maximizing the constructive, metacognitive capabilities presumed to issue from such double-coding.  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

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

Through a physical, historical and epistemological analysis it is shown how much is wrong with the idea that relates impetus theory to a non-grown-up physical and epistemological conception. Indeed, it yields that impetus theory of Buridan and Oresme can be formalised and can furnish us a natural, non-violent interpretation of (classical) mechanics as well as a more general, physical hermeneutics of the world. Then, the possible relevance of impetus theory for science education is strongly pointed out.  相似文献

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

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.

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

The results of an experimental study investigating the influence of problem familiarity on learning in a problem-based psychology course are presented. Participants worked with either a familiar or an unfamiliar version of the same problem. The following measurements were taken (1) a measure of problem quality as perceived by students, (2) number of explanations of the problem put forward by the students while discussing it, (3) quality of learning issues derived from the discussion, (4) amount of time spent on self-study, and (5) the amount of knowledge acquired as indicated by a test. The results demonstrate that participants in the familiar problem condition perceived the problem to be of higher quality than the participants in the unfamiliar problem condition. No significant differences in learning were found. The findings do suggest, however, that problems may be improved by making them more relevant to the everyday experience of students.  相似文献

This study investigated, in the context of mathematical problem solving by secondary school students, the nature of the visual schemata which Johnson (1987) hypothesises mediate between logical propositional structures and rich specific visual images. Four groups of grade 10 students were studied, representing all combinations of high and low operational ability in mathematics (equivalent to Johnson's logical propositional structures) and high and low vividness of visual imagery (corresponding to Johnson's rich images). The results suggested first, that success at problem solving was related to logical operational ability, but not to vividness of visual imagery. Second, a variety of visually based strategies were used during problem solving which differed in their level of generality and abstraction, and use of these strategies appeared related to either logical operational ability or vividness of visual imagery, depending on their level of abstraction. The results supported Presmeg's (1992b) continuum of abstraction of image schemata.Throughout the paper, the first High or Low denotes logical operational ability, and the second, vividness of visual imagery.  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

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.

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

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

Fifty-five college women enrolled in competency-based, humanistic or self-directed education programs completed their California Personality Inventory and listed five reasons for selecting their program. CPI results indicated that self-directed students scored lower than other students on the Femininity Scale (p.001). Using Chickering's seven vectors of change as a framework, the study found competency-based students identifying purpose and competence, humanistic students identifying inter-personal relationships and integrity, and self-directed student identifying autonomy and purpose as reasons for enrolling in their nontraditional programs. The study used these results to question the mythology that adherents to different programs are of different personality types and to argue that differences in perceptions of purpose in education distinguish students in the three programs.  相似文献

Computers, once available exclusively to wealthy industries, are now rapidly becoming as familiar in preschool and kindergarten classrooms as block and crayons. Articles making claims such as Learning by Computers at Age 4 and Computers Preparing Preschoolers for Kindergarten now permeate the news media. Increasing numbers of child care centers, attempting to maximize public interest in computers, now readily advertise Computer Tutor in their literature. Computer Tutor is often even listed above other important qualifications such as certified teachers and professional affiliations of centers.Theresa Rubens has had extensive experience working with children in both family day homes and child care centers.

Relationships between graduate education and academic research are intuitively accepted, but have been given limited examination. Using concepts suggested by Merton and Hagstrom, this study developed measures of recognition and association to assess student awareness of ambient research in their departments. Usefulness of campus research for the respondent's own work was explored in terms of the kinds of utility and its relative importance compared to other resources. A mailed survey of a sample of Ph.D. recipients in 18 departments from a major research university brought a 68% usable return, 470 subjects. Findings show a high level of research awareness, about 70%. The major utilities of research for doctoral students are identified as the theoretical leads and basic data sources.  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.

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
