The conflicts of postmodern and traditional epistemologies in curricular reform: A dialogue

A radical opponent of Western higher education asserts that its pedagogy and content depend on belief in objective truth and knowledge. This epistemology and education are attacked as exclusive and domineering toward women, minorities, and non-Westerners. The critic puts forward a pragmatist epistemology, leading to multi-cultural education aimed at social criticism and personal autonomy. The critic's dialogue with a defender of traditional epistemological ideas provides a critical introduction to the claims justifying many radical criticisms of Western curricula and pedagogy.     

What is educational theory and how to make it?

An analysis is provided detailing the conditions for the appropriate theoretical study of the object of educational science: pedagogy.     

Pierre de La Ramée et le déclin de la rhétorique

This article provides a basic general introduction to Ramus, and evaluates his role in the history of logic and rhetoric, especially with relation to the study of argumentation. The author agrees with Ong and other historians of logic that Ramus is not to be taken seriously as a logician, and that his undoubted importance in the history of ideas is to be found elsewhere.Ramus advocates a belief in nature, experience and reason, and rejects the reliance on the authority of ancient philosophers, above all Aristotle, though experience does not mean scientific experiment and, paradoxically, includes the example of great philosophers and writers. In the end Ramus is seen as responsible for substituting for ancient classical rhetoric an entirely ornamental rhetoric of figures which was to take over education (with the exception of the Jesuit schools) almost until our own day. This curtailing and diminishing of rhetoric is seen as a degeneration. Ancient five-part rhetoric had been concerned with convincing and persuading: Aristotle distinguished the analytic, scientific reasoning of logic, from dialectic which was based on opinion and probability and had close links with rhetoric; by the time of Cicero and Quintilian, who addressed themselves to jurists and politicians, logic has given way to dialectic. In the Middle Ages and the Renaissance the two become assimilated; the evolution of this is traced here through the thirteenth-century Summulae logicales of Peter of Spain to the fifteenth-century German humanist logician Rudolph Agricola, who influenced Ramus partly through the intermediary of Johann Sturm. Ramus took over their topical theories but restricted them to logic/dialectic, and left rhetoric with little more than tropes and figures. He believed that there was only one method for teaching all the arts, and one dialectic common to them all. The distinction between analytical and dialectical has disappeared, with far-reaching consequences for the study of argumentation. Over the centuries logic has lost its connection with controversy and persuasion. With the development of the post-Cartesian, post-Baconian emphasis on the clarity of scientific discourse, and the mid-nineteenth-century interest in mathematical and formal logic, the process was complete. Argumentation, or the new rhetoric, aims to fill the gap thus created.

     

The role of the psychologist expert witness: Provider of perspective and input

The definition and role of the expert witness is reviewed. Two conceptual systems for viewing the world, the scientific method and the adversarial system, are compared. The reconciliation and integration of these two discrepant systems are discussed in terms of input versus outcome. The rules of evidence, as well as problems of communication between the systems, are reviewed with the aim of providing expert witnesses with a better understanding of effective testimony. Finally, collaboration between the two systems is called for in order to provide guidelines for both neuropsychologists and attorneys.     

The place of human values in the language of science: Kuhn,Saussure, and structuralism

The current paradigm in medicine generally distinguishes between genetic and environmental causes of disease. Although the word paradigm has become a commonplace, the theories of Thomas Kuhn have not received much attention in the journals of medicine. Kuhn's structuralist method differs radically from the daily activities of the scientific method itself. Using linguistic theory, this essay offers a structuralist reading of Thomas Kuhn's The Structure of Scientific Revolutions. Our purpose is to highlight the similarities between these structuralist models of science and language. In part, we focus on the logic that enables Kuhn to assert the priority of perception over interpretation in the history of science. To illustrate some of these issues, we refer to the distinction between environmental and genetic causes of disease. While the activity of scientific research results in the revision of concepts in science, the production of significant differences that shape our knowledge is in part a social and linguistic process.     

Performance of humans in concurrent avoidance/positive-reinforcement schedules

Performance maintained under concurrent schedules consisting of a variable-interval avoidance component and a variable-interval positive-reinforcement component was studied in three human subjects using points exchangeable for money as the reinforcer. The rate of responding in the avoidance component increased, and the rate of responding in the positive-reinforcement component declined, as a function of the frequency of point-losses avoided in the avoidance component. The performance of all three subjects conformed to equations proposed by Herrnstein to describe behavior in concurrent schedules. The logarithms of the ratios of the response rates in the two components, and the logarithms of the ratios of the times spent in the two components, were linearly related to the logarithms of the ratios of the frequency of loss avoidance in the avoidance component to the frequency of reinforcement in the positive-reinforcement component. When a changeover delay of 5.0 sec was imposed, the slopes of the linear functions were close to 1.0 in the case of two subjects, whereas the third subject exhibited significant undermatching. For two subjects the changeover delay was then reduced to 2.0 sec; in both cases the slopes of the linear functions were lower than under the 5.0-sec condition. One subject participated in a third phase, in which no changeover delay was imposed; there was a further reduction in the slopes of the linear functions.     

On the self-perpetuating nature of stereotypes about women and men

An experiment was conducted to investigate an interpersonal process that contributes to the perpetuation of stereotyped beliefs about women and men. Male-female pairs of unacquainted individuals interacted to negotiate a division of labor on a series of work-like tasks (that differed in their sex-role connotations) in a situation that permitted control over the information that male perceivers received about the apparent sex of female targets. The perceivers' beliefs about the sex of their targets initiated a chain of events that resulted in targets providing behavioral confirmation for perceivers' beliefs about their sex. Targets believed by perceivers to be male chose tasks relatively masculine in nature, and targets believed by perceivers to be female chose tasks relatively feminine in nature. Although this behavioral confirmation effect was initially elicited as reactions to overtures made by perceivers, it persevered so that eventually targets came to initiate behaviors “appropriate” to the sex with which they had been labeled by perceivers. The specific roles of perceivers and targets in the behavioral confirmation process are examined. Implications of these findings for the perpetuation of stereotyped beliefs about the sexes are discussed.     

Comparison of observational recordings in vivo, via mirror, and via television

Simultaneous observational recordings were made in vivo, via an observation mirror, and via closed circuit television. Three of nine observers had extensive experience recording behavior in vivo; three had extensive experience recording behavior via mirror; and three had extensive experience recording via television. Observers recorded nine categories of disruptive behavior for children in a special class setting. Frequencies of behavior recorded in vivo, via mirror, and via television differed significantly for only one category, vocalization. There were no significant main effects or interactions involving the observers' previous experience. Occurrence reliability coefficients computed within and between media demonstrated the similarity of observer agreement in all three media. Data collection procedures using an observational mirror or closed circuit television appear to be reasonable alternatives to in vivo observation in circumstances similar to those in the present study.
