The global expansion of mass schooling has greatly increased opportunities for low-income families, and governments have devoted much effort to equalising access and quality in education systems. Alongside regular schooling, the so-called shadow education system of private supplementary tutoring has grown rapidly across the world. The fact that rich families can purchase more and better quality shadow education undermines the achievements of increased equality of opportunities in formal schooling. Drawing on a mixed-methods study in Shanghai, China, the article shows how shadow education has offset school equalisation policies through differentiation of access and through sorting mechanisms. Shadow education occupies a space beyond strict government control in which privileged families and elite schools ignore and mediate the equalisation policies, seeking competitive advantages. Uneven access to shadow education and tracking within it shape, maintain, and exacerbate inequitable schooling experiences at individual and institutional levels.  相似文献

Applying abstract ethical principles to the practical business of building a code of applied ethics for a technical communication department teaches students that they share certain unarticulated or even unconscious values that they can translate into ethical principles. Combining abstract theory with practical policy writing can teach technical communication students to become increasingly aware of ethical actions without restricting ethics solely to abstractions or rules.  相似文献

In many publications, Sjödén, Archer, and their colleagues have studied conditioned taste aversions and found that in addition to taste, the bottle and/or spout containing a solution exerts strong control over the expression of an aversion. For example, Sjödén and Archer claim that this bottle stimulus will support a bottle-illness association even with long delays between the bottle and illness and after only a single conditioning trial. They have interpreted their results as indicating that contextual effects are important in taste-aversion learning. However, a confound in their procedure, stemming from the bottles they used, could explain their results in a simple way. Sjödén and Archer have emphasized that the bottle stimuli they used to distinguish between contexts consisted of one of two different sizes of drinking spouts, the larger of which made a clicking noise when licked. However, the larger spouts were always attached to plastic bottles and the smaller spouts were always attached to glass bottles. If discriminable tastes from the plastic bottles existed, then taste may have been inadvertently manipulated. Support for the likelihood of a plastic taste includes the seminal work on taste-aversion learning that stemmed from the serendipitous use of plastic bottles in the cage that rats were irradiated in and glass bottles in the home cages (see Garcia, McGowan, & Green, 1972). In these early demonstrations, rats learned to avoid the taste of water in the plastic bottles but not the taste of water in the glass bottles.  相似文献

In human infancy, 2 criteria for intentional communication are (a) persistence in and (b) elaboration of communication when initial attempts to communicate fail. Twenty-nine chimpanzees (Pan troglodytes) were presented with both desirable (a banana) and undesirable food (commercial primate chow). Three conditions were administered: (a) the banana was delivered (successful communication), (b) half of the banana was delivered (partially successful communication), and (c) the chow was delivered (failed communication). The chimpanzees exhibited persistence in and elaboration of their communication in every condition except when the banana was delivered. Thus, their communication was about a specific item, demonstrating that both intentionality and nonverbal reference are capacities shared by humans with our nearest living relatives, the great apes.  相似文献

New Caledonian crows make and use tools, and tool types vary over geographic landscapes. Social learning may explain the variation in tool design, but it is unknown to what degree social learning accounts for the maintenance of these designs. Indeed, little is known about the mechanisms these crows use to obtain information from others, despite the question’s importance in understanding whether tool behavior is transmitted via social, genetic, or environmental means. For social transmission to account for tool-type variation, copying must utilize a mechanism that is action specific (e.g., pushing left vs. right) as well as context specific (e.g., pushing a particular object vs. any object). To determine whether crows can copy a demonstrator’s actions as well as the contexts in which they occur, we conducted a diffusion experiment using a novel foraging task. We used a nontool task to eliminate any confounds introduced by individual differences in their prior tool experience. Two groups had demonstrators (trained in isolation on different options of a four-option task, including a two-action option) and one group did not. We found that crows socially learn about context: After observers see a demonstrator interact with the task, they are more likely to interact with the same parts of the task. In contrast, observers did not copy the demonstrator’s specific actions. Our results suggest it is unlikely that observing tool-making behavior transmits tool types. We suggest it is possible that tool types are transmitted when crows copy the physical form of the tools they encounter.  相似文献

We examined the use of a problem-solving intervention to teach classroom skills to a student with moderate intellectual disabilities. She was receiving her education in regular classrooms at her local primary school. The student was taught the targeted skills in a resource room removed from the regular classroom. She successfully generalised the skills to regular classrooms. The problem-solving intervention was evaluated using a multiple baseline design across classrooms. Regular classroom teachers indicated that the student's behaviour significantly improved during the intervention.  相似文献

In Third World countries a key to the course of nation-building is the modernization of the organizational and administrative infrastructures which drive the development process. Increasing the operational capabilities, effectiveness, and efficiency of the ministry of education, and hence the quality and quantity of school outcomes, is typically a high priority item in the development plans of a nation. In order to promote the modernization of management activities in ministries, however, it is first essential to understand their existing patterns of operation. Toward this objective, the paper presents a methodological framework for a field study approach to the examination of the working of a ministry of education in Latin America. Several issues are introduced which influence the process of inquiry, such as: (1) examining the impact of historical traditions on contemporary management procedures; (2) exploring concerns for ethics and academic colonialism; (3) distinguishing between anthropological and sociological participant-observation field methods; (4) gathering and analyzing data on complex ministries; and (5) exploring the task of Third World theory building.
Zusammenfassung Einen Schlüssel zum Verlauf des nationalen Aufbaus in der dritten Welt liefert die Modernisierung der organisatorischen und administrativen Infrastrukturen, die den Entwicklungsprozess vorantreiben. Im allgemeinen wird der Verbesserung der Handels-Fähigkeiten, der Wirksamkeit und Effizienz des Bildungsministeriums eine hohe Priorität in den Entwicklungsplänen eines Landes beigemessen. Um jedoch die Modernisierung der Führungsarbeit von Ministerien beschleunigen zu können, müssen zunächst ihre jetzigen Operationsweisen untersucht werden. Zu diesem Zweck wird in diesem Artikel ein methodologischer Rahmen für einen Feldstudienansatz zur Prüfung der Arbeit eines Bildungsministeriums in einem lateinamerikanischen Staat vorgelegt. Verschiedene Fragen, die den Untersuchungsprozeß beeinflussen, werden erörtert, zum Beispiel; (1) die Auswirkung historischer Traditionen auf derzeitige Leitungsverfahren; (2) Grad der Beachtung von Ethik und akademischem Kolonialismus; (3) Unterschied zwischen anthropologischen und soziologischen Methoden zur Beobachtung von Beteiligten in der Praxis; (4) Sammlung und Analyse von Daten über komplexe Ministerien; und (5) die Aufgabe, in der dritten Welt eine Theorie aufzubauen.

Résumé L'un des éléments essentiels de la course à l'intégration nationale, dans les pays du Tiers Monde, est la modernisation des infrastructures administratives et organiques qui guident le processus du développement. L'une des premières priorités à respecter est typiquement le développement des moyens d'action, de la compétence et de l'efficacité du ministère de l'éducation, et par voie de conséquence, la qualité et l'importance des résultats scolaires. Toutefois, afin de moderniser judicieusement les activités du management dans les ministères de l'éducation, il est primordial de comprendre leur mode actuel de travail. Ayant cet objectif en vue, l'auteur de cet article propose un cadre méthodologique permettant d'aborder sur le terrain l'examen du fonctionnement d'un ministère de l'éducation en Amérique Latine. Il expose plusieurs démarches qui influent sur le processus de l'enquête: (1) examiner l'impact des traditions historiques sur les procédés contemporains du management; (2) déterminer les préoccupations relatives à l'éthique et au colonialisme académique; (3) faire la distinction entre les méthodes anthropologiques et sociologiques de l'observation participante sur le terrain; (4) rassembler et analyser les données concernant les ministères complexes; et (5) explorer la tâche de l'élaboration de théories relatives au Tiers Monde.
