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

ASK to THINK—TEL WHY®© is an inquiry-based model of mutual peer tutoring in which tutoring partners mediate each others' learning in a transactive manner. This tutorial model is designed as a person-plus cognitive partnership that supports the distribution of cognition and metacognition in order to promote complex, higher-level learning. This article focuses on what is being distributed during ASK to THINK—TEL WHY®© (i.e., the cognitive tasks of questioning, explaining, thinking, problem solving, as well as monitoring and regulation of learning) and how these cognitions are distributed across the tutoring pair and various aspects of their learning environment. Results of research on the effectiveness of using this model in classroom contexts has shown that the model promotes students' construction of new knowledge. 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

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

TACTICS (French and Spanish acronym standing for Collaborative Work and Learning in Science with Information and Communications Technologies) is an ongoing project aimed at investigating a distributed community of learning and practice in which information and communications technologies (ICT) take the role of collaborative tools to support social construction of knowledge. This community is composed of researchers, graduate students, and high-school teachers and their students, from six schools and four universities in Canada and Mexico. It set out in fall 2000 to develop a community around the general topic of integrating concepts in science school subjects. Once a prototype community is established, it can become a terrain where different aspects could be studied. Subsequently, researchers could gradually take a back seat allowing as well as ensuring the autonomy of the school members involved and, thereby, the viability of the learning community. The set up of the proposed prototype distributed science learning community was therefore an essential yet far from trivial first step. This paper discusses the process of setting up the community and the lessons learned. 相似文献

“It's Easier to Be Yourself When You Are Invisible”: Female College Students Discuss Their Online Classroom Experiences 总被引：6，自引：0，他引：6
Patrick Sullivan 《Innovative Higher Education》2002,27(2):129-144
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

On the assumption that colleges need a theory which specifies what they should be trying to do and how they should do it, two popular theories of this sort are described. Bundle of knowledge theory rests on the idea that education should impart pieces of knowledge which can be assessed by behavioral criteria with methods based on established principles of learning. Developmental stage theory holds that education should help students move through a sequence of general stages towards maturity. A third theory called component theory, is then sketched, in which the idea of general stages is disputed and the idea of component abilities of intellectual processes substituted. This theory has implications which are similar to those of stage theory if it is combined with certain moral assumptions about the goals of college education, namely that its purpose is to help students form and pursue life plans which are both rational and just. 相似文献

Alfred North Whitehead's theory of learning is best understood in the overall context of his process philosophy. The rhythmic cycles of growth forming the basis of human learning (romance, precision, and generalisation) are organically connected to the characteristics of life typifying all entities in the universe (self-enjoyment, creative activity, and aim).The kind of balanced education which best enhances growth and connectedness is one in which art and aesthetic appreciation in the broadest sense are dominant. By experiencing the beauty of the sunset, for example, children and adults have access to feelings that flow through them from the world and connect them to distant events taking place in space and time. These bodily feelings at the base of all experience provide concrete ways in which human beings can appreciate the intrinsic value of the world around them.By way of contrast, the methods of 17th century science replace our concrete experience of the sunset with abstract categories that are used to measure the phenomena in question and deny the importance of that experience in understanding the world. Schools' and universities' emphasis upon this methodology produces an imbalanced education with minds in a groove.A renewal of balance in education helps us to understand the false dichotomy between child-centered and and curriculum-centered education. Education for Whitehead must pay attention to both. Moreover, he understands that the academic freedom enjoyed by bands of imaginative scholars in universities is not an article of commerce to be sold to the highest corporate bidder but something to be valued for its intrinsic worth. 相似文献

Lower division courses are typically perceived by students as blow-off courses. We can overcome this image. This paper contrasts active and passivelearning environments, and describes efforts to create an active, critical learning environment in both Introduction to Sociology and The Family System-typical lower division courses in Sociology. A review of grade distributions, quantitative course evaluations, qualitative course evaluations, and a survey asking students to subjectively compare the active learning course structure to the typical multiple choice format provide evaluation data. Finally, the paper discusses problems in using these innovations.Randy Stoecker recently received a Ph.D. in Sociology from the University of Minnesota, and has been exploring alternative pedagogies since 1982. He has published in the areas of social theory and social movements. An earlier version of this paper was presented at the Midwest Sociological Society Annual Meetings, Minneapolis, Minnesota, 1988.

A review of the study behaviour of first-year Engineering students was undertaken in order to investigate two sets of influencing factors. The first part of the study reviewed these students' selfreported retrospective study behaviour in the context of secondary school Science, while the second part focused on their approaches to the study of Applied Mechanics as a core undergraduate degree course. Utilising qualitative interview data as the source of evidence, the study highlights the following important conclusions: (1) some traditional first-year students embark on their studies as much at risk academically as their nontradition counterparts; (2) many first-year Engineering students encounter workload pressures which lead to their adopting increasingly strategic approaches to their studies in individual courses; (3) the complex, qualitatively different learning needs of these students make it exceedingly difficult to design teaching programmes which will appropriately address these learning needs. The study suggests that these conclusions cannot, in spite of these difficulties, simply be ignored in the hope that they will resolve themselves. 相似文献

In this article, the actual impact on students' instructional and epistemological beliefs of systematic attempts to implement a problembased, collaborative and technologicallyrich learning environment in regular, internationallyspread, secondary school classrooms is described. Although the literature suggests that learning environments do affect both categories of beliefs, empirical evidence is currently limited. To study the effects of learning environments, classroombased learning environments were redesigned in various respects. The change entailed the implementation of a problembased, collaborative and technologicallyrich environment to replace the more regular contentdriven, teachercentred and textbookbased environment. The implementation of the innovation was hypothesised to result in a change of both the instructional and epistemological beliefs of students. Moreover, these beliefs were expected to evolve in the direction of the assumptions underlying the innovative environment. A classical pretest and posttest study resulted in the confirmation of the first hypothesis. However, for the second hypothesis, the opposite was found: students' beliefs strengthened in a direction that contradicts the basic principles underlying the designed environment. The study highlights that a poor implementation of potentially powerful learning environments can result in unexpected and even undesirable side effects. 相似文献

The objective of this study is to analyze secondary school students' interactions (conflicts, controversies, and arguments) as they participate in an intact classroom activity designed to facilitate their understanding of heat energy and temperature. The study is based on 32 ninth-grade students in a public school in Londrina, Brazil. Results obtained show that the differentiation between heat energy and temperature constitutes considerable difficulties for the students, and can be considered as part of the hard-core of their understanding (Lakatos, 1970, Criticism and the Growth of Knowledge, Cambridge University Press, Cambridge, UK, pp. 91–196). Student interactions (video taped) were classified into an Alternative Model, Transitional Model, and Scientific Model, depending on the degree to which they reflected a progressive transition in their hard-core. Students generally resisted a change in their conceptual understanding. Some students were able to question the hard-core of their beliefs and construct a Transitory Model. Some students experienced a further progressive transition by constructing a Scientific Model, based on the understanding that Temperature only measures the energy of agitation. Methodology used also provided a glimpse of how a particular student grappled with the conflicts in order to facilitate progressive transition in understanding. It is concluded that given the opportunity to discuss, reflect, consider alternative/conflicting situations, students can construct models that increase progressively in their heuristic/explanatory power. 相似文献

Exploring the Concept of ‘Habitus’ with Preservice Teachers Through the Use of Popular School Films 总被引：1，自引：0，他引：1
James Trier 《Interchange》2002,33(3):237-260
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

The paper considers two basic models of the teaching-learning process, described as the didactic and the communication model. These are applied to Computer Assisted Learning (CAL) in order to demonstrate that CAL has generally embodied a didactic model of teaching and learning. This imposes an unnecessary restriction on the student's freedom to choose their (Note 1) learning style, and the paper discusses how it is possible for CAL to support a less didactic model and to give more control to the student. 相似文献

Many forces are shifting the role of the nation-state and altering our fundamental understanding of how it should function. The author argues that the transplanted European model of the nation-state has become dysfunctional, creating national minorities, serving as an ideological cloak for various forms of oppression and opposing forms of education that would promote diversity of languages and cultures. The decline of territorial sovereignty under the forces of globalization, the move to supranational forms of organization and the emergence of sub-national areas of economic and social development (often city-regions) provide a new range of opportunities for development of minority schooling.
Zusammenfassung Viele Kräfte verändern die Rolle des Nationenstaates und ändern damit auch unser grundsätzliches Verständnis zu dessen Funktion. Der Autor argumentiert, daß das übertragene europäische Modell des Nationenstaates außer Funktion gesetzt und damit nationale Minderheiten geschaffen wurden. Somit besteht ein ideologischer Deckmantel für verschiedene Arten von Unterdrückung und Widerstand gegen Erziehungsarten, die eine Vielfalt der Sprachen und Kulturen fördern würden. Der Verfall territorialer Unabhängigkeit unter den Kräften der Globalisierung, die Bewegung hin zu einer supranationalen Form der Organisation und die Schaffung regionaler Gebiete wirtschaftlicher und sozialer Entwicklung (oft Stadtbezirke) bieten neue Entwicklungsmöglichkeiten hinsichtlich der Schulbildung für Minderheiten.
Resumen Son muchas las fuerzas que están cambiando el papel que desempeña el estado-nación y que alteran nuestro concepto básico de cómo este debería funcionar. El autor argumenta que el modelo europeo trasplantado del estado-nación se ha vuelto disfunctional, creando minorías nacionales y sirviendo de manto ideológico para encubrir diferentes formas de opresión y de oposición a una educación que intenta promover la diversidad de lenguas y culturas. El ocaso de la soberanía territorial bajo las fuerzas de globalización, el cambio hacia formas de organización supranacionales y el surgimiento de sectores subnacionales de desarrollo económico y social (frecuentemente en regiones urbanas) proveen un nuevo tipo de oportunidades para el desarrollo de una educación escolar de minorías.
Résumé De nombreuses pressions modifient le rôle de l'Etat-nation et transforment notre conception fondamentale de son fonctionnement. L'auteur expose que le modèle européen d'Etat-nation qui a éé transposé dans d'autres régions est maintenant atteint de dysfonctionnement, car il crée des minorités nationales, sert de prétexte idéologique à différentes formes d'oppression et fait obstacle à des modèles d'éducation qui encourageraient la diversité des langues et des cultures. Le déclin de la souveraineté territoriale sous la pression de la mondialisation, l'évolution vers des formes d'organisation supranationales et l'apparition de concentrations régionales du développement éconnomique et social (souvent en tant que régions urbanisées) constituent de nouveaux stimulants pour l'élaboration d'une scolarité adaptée aux minorités.

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

This study employed the Semantic Differential technique to investigate the relationship between informal interaction with students and the accuracy with which faculty members project students' perceptions of the institutional climate at two colleges of Arts and Sciences. When subdivided into nominal categories of high, moderate, and low interactors on the basis of their frequency of informal, out-of-class contacts with students, high interactors were found to project consistently more accurate student ratings of the climate on a bureaucracy factor than low interactors. A similar, though not consistent, relationship was found between high and low interactors on an intellectualism/scholarship dimension. 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

Alternative frameworks,conceptual conflict and accommodation: Toward a principled teaching strategy 总被引：3，自引：0，他引：3
Students' alternative frameworks (frequently regarded as misconceptions) play a crucial role in science concept learning. Accumulated research findings indicate that alternative frameworks are resistant to extinction despite formal instruction.This paper presents an instructional strategy based on the thesis that science concept learning involves cognitive accommodation of an initially held alternative framework. The strategy consists of three phases: (1) exposing alternative frameworks, (2) creating conceptual conflict, (3) encouraging cognitive accommodation. The first phase is facilitated through an exposing event, while the second and third focus on a discrepant event.The authors have used previous research findings about student alternative frame-works for the structure of a gas to create exposing and discrepant events for an introduction to the particle model of gases. The paper presents a case study of two lessons in a sequence on the particle model, accompanied by an analysis of the phases of the instructional strategy employed for cognitive accommodation.Based on a paper presented at the AERA convention, Los Angeles, California, April, 1981.This paper was prepared while the first author was a visiting professor at Cornell University, Ithaca, New York. 相似文献

This article reviews the learning process and ways in which it can hinder or contribute to intellectual development, the development of critical consciousness (as defined by Paulo Freire), and social change. Interviews with students illustrate that Freire's concepts are applicable to understanding the process students describe as they extrapolate the hidden curriculum, examine the effect on their learning process, and struggle to free themselves from this socialization process. In conclusion, questions are raised about the relationship between alternative educational programs and social change. 相似文献
