Context sensitivity of conditioned suppression following preexposure to the conditioned stimulus

Conditioned suppression in rats is often unaffected when the context (or set of background stimuli) is changed following conditioning. This suggests that responding to the conditioned stimulus (CS) can be relatively insensitive to the context in which the CS is presented. In two experiments, we examined whether sensitivity to contextual stimuli is affected by preexposure to the CS. In Experiment 1, when the CS was novel at the outset of conditioning, conditioned suppression was not affected when the context was changed following conditioning. However, when the CS had been preexposed, responding was weaker when extinction occurred outside of the conditioning context. In Experiment 2, responding was again sensitive to the test context, regardless of whether preexposure occurred in the conditioning context or in an alternate context. These results suggest that the extent to which responding is sensitive to context can depend on the conditioning history of the CS.     

Feminine sexual desire and shame in the classroom: an educator’s constructions of and investments in sexuality education

ABSTRACT

Within the growing body of literature on sexuality education in South Africa, researchers have highlighted how teachers may face, or themselves be, barriers to the implementation of rights-based comprehensive sexuality education. Important issues with regard to educators are: firstly, the social and discursive space within which educators are located; and secondly, the complex emotional and psychic investments that educators take up within particular discourses and practices. This paper explores, through a psychosocial reading of an interview extract with a particular educator based in the Eastern Cape of South Africa, how discursive and psychic concerns are sutured within the complex subjectivity of the educator as the medium for sexual education in schools. Specifically, it highlights the numerous ways in which feminine sexuality and desire may be avoided, denied and silenced. Even when feminine desire is specifically evoked as in this case, it is done so in a way that ensures social and cultural respectability, thereby reproducing shame narratives that form and maintain traditional gender discourses. Our analysis demonstrates how engaging with educators as subjects with their own sexual history and psychic dynamics, and as individuals with raced, gendered and classed identities, is a potentially transformative perspective for effective sexuality education.     

School-site decision making in multicultural education: An Australian perspective

This paper examines a number of issues related to multicultural education and curriculum change. It focuses on school-level projects that were developed in Western Australian schools from 1979–1981. The results of the research raised the following points: teachers viewed multicultural education as a psycho-social rather than a socio-political phenomenon; the aims of multicultural education were seen to be best achieved by the collection of specific resource material; on-site implementation of the projects often led to changes being made to the original intentions of the project designers; qualitative research techniques proved more sensitive in portraying and consequently understanding the complexities associated with project implementation, and, finally, it seemed clear that more emphasis should be placed on understanding the role of the teacher as a policy mediator. It is at the school level that the final decisions are made about national policy intentions.

Zusammenfassung In diesem Bericht werden eine Anzahl von Fragen untersucht, die sich mit der Veränderung in der multikulturellen Erziehung und im Curriculum beschäftigen. Der Schwerpunkt liegt auf Projekten für Schulabgänger, die in Schulen Westaustraliens in der Zeit von 1979–1981 entwickelt wurden. Einige der Ergebnisse waren: Lehrer sahen multikulturelle Erziehung weniger als ein psychopolitisches, mehr aber als ein psychosoziales Problem; die Zielvorstellungen der multikulturellen Erziehung erschienen am besten an Hand spezifischen Quellenmaterials erreichbar; bei der Anwendung der Projekte waren häufig Abänderungen der ursprünglichen Intentionen der Projektdesigner erforderlich; qualitative Forschungstechniken erwiesen sich bei der Darstellung und infolgedessen bei dem Verständnis der mit der Projektausführung verbundenen komplexen Umstände als besonders geeignet. Schließlich wurde deutlich, daß die Rolle des Lehrers als Vermittler der Bildungspolitik mehr Aufmerksamkeit zuzudenken ist. Auf der Schulebene fallen die endgültigen Entscheidungen über die Intentionen der nationalen Bildungspolitik.

Résumé Ce document étudie un certain nombre de problèmes relatifs à l'éducation multiculturelle et aux changements qu'il peut occasionner au niveau du curriculum. Il place un accent sur les projets concernant l'école qui ont été dévelopés en Australie occidentale de 1979 à 1981. Les résultats de ces recherches ont soulevé un certain nombre de points: les enseignants ont considéré l'éducation multiculturelle plutôt en tant que phénomène psycho-social que socio-politique et il s'est avéré que les objectifs de l'éducation multiculturelle pouvaient être le mieux atteints en réunissant des matériels de référence spécifiques; la mise en oeuvre sur place a souvent conduite à des changements qui ont été apportés aux premières intentions des planificateurs du projet; les techniques de recherche qualitative se sont montrées le plus efficaces dans la définition et par conséquence dans la compréhension des problèmes liés à la mise en oeuvre du projet et finalement, il a semblé qu'un accent soit placé sur la définition du rôle de l'enseignant en tant que médiateur politique. C'est au niveau de l'école que les décisions finales sont prises en ce qui concerne les intentions politiques nationales.

     

Teachers' perceptions of the effects of a scientific literary course on subsequent learning in biology

Five teachers were interviewed as to their perceptions of the effect of an intervention to teach scientific literacy on learning in subsequent biology courses. The sample consisted of 450 students who had a literacy course in ninth grade and had completed tenth-grade biology. At the end of the academic year the biology teachers were interviewed and asked to compare the biology students who had the literacy course to students they had taught in earlier years. The biology teachers concluded that the literacy course did have an effect on students' subsequent ability to learn biology. The strength of the effect varied according to level of biology. Students had a better understanding of the nature of science and better laboratory and process skills. They were also better at analyzing data. The advanced and intermediate biology students were more creative, more likely to take risks, and engage in hypothetical thinking than other groups of students that the teachers had taught. Although the purpose of the literacy course was to teach literacy skills the advanced students retained a substantial amount of content material that was applicable to biology.     

The instructor self-evaluation form: Development and validation of an ipsative forced-choice measure of self-perceived faculty performance

An ipsative forced-choice college faculty self-evaluation questionnaire was developed. The instrument was validated by comparing self-evaluation scores to student rating scores and by comparing superior and nonsuperior instructors on the basis of student ratings. Both analyses yielded positive, but modest, indications of validity. Implications are discussed relative to the questionnaire's utility in faculty development activities.     

Education reform and subject matter knowledge

This article raises the question of what K–12 teachers need to know to teach mathematics and science well. It begins by examining reform proposals for K–12 science and mathematics teaching with an eye toward defining what good teaching practice consists of. It then examines a wide range of literature to delineate the varieties of knowledge that have been associated with this kind of teaching. While the focus is on subject matter knowledge, the article addressed the character of that knowledge rather than the content of that knowledge. Types of knowledge identified in the literature include conceptual understanding of the subject, pedagogical content knowledge, beliefs about the nature of work in science and mathematics, attitudes toward these subjects, and actual teaching practices with students. The literature is incomplete with respect to which of these is relatively more or relatively less important. © 1998 John Wiley & Sons, Inc. J Res Sci Teach 35: 249–263, 1998.
