This article will consider the claim that the possession of concepts is innate rather than learned. Innatism about concept learning is explained through consideration of the work of Fodor and Chomsky. First, an account of concept formation is developed. Second the argument against the claim that concepts are learned through the construction of a learning paradox developed by Fodor is considered. It is argued that, despite initial plausibility, the learning paradox is not, in fact, a paradox at all as it rests on eliding the distinction between recognising something and recognising it as a something. The plausibility of eliding this distinction rests, in turn, on begging the question as to whether concept possession is a necessary condition for recognition of objects, events, properties etc. Fodor's positive arguments for innatism, as set out in LOT2 are considered and parallels with his account of stereotype formation and associationist accounts of concept formation are considered. The explanatory persuasiveness of this revised account of concept activation through the generation of stereotypes is weak. The article then examines the distinction between concept possession and concept mastery in greater detail, arguing that innatists have difficulty in accounting for the phenomenon of concept mastery, including within the contexts of formal and professional education.  相似文献

One of the major shifts in education today under the influence of information and communication technologies is that there is an increased tendency toward the use of computer-mediated communications (CMC). CMC has developed an assortment of methods from simple e-mail to wireless instant messages and synchronous and asynchronous discussions. A large portion of the research in this area focuses on the pedagogical aspects of CMC particularly on the use, strategies, effectiveness and the integration of the new technologies for teaching and learning. Some studies investigate different perspectives of interaction like keeping track of asynchronous discussion, quality of participation, interaction and collaborative or group learning. This paper reports findings from the study that examines the quality of message ideas, thinking and interaction in an asynchronous CMC environment in a teacher training institution. The authors suggest some practical strategies in the implementation of asynchronous discussions in CMC environment. La qualité des messages d’idées, de la pensée et de l’interaction dans un environnement CMC asynchrone. Un des changements majeurs dans l’éducation aujourd’hui sous l’influence de l’information et des technologies de la communication est une tendance accrue À l’usage des communications par ordinateur (Computer-mediated Communications CMC). CMC a permis le développement de tout un assortiment de méthodes depuis de simples e-mail jusqu’À des messages sans fil instantanés et des discussions synchrones et asynchrones. Une grande partie de la recherche en ce domaine est centrée sur les aspects pédagogiques des CMC en particulier sur l’emploi, les stratégies, l’efficacité et l’intégration des nouvelles technologies pour l’enseignement et l’apprentissage. Certains études examinent les perspectives différentes de l’interaction. Telles que garder la trace des discussions asynchrones, la qualité de la participation interaction et l’apprentissage en coopération ou en groupe. L’article rapporte les résultats de l’étude qui examine la qualité des messages d’idées, la pensée et l’interaction dans un environnement de CMC asynchrone dans un établissement de formation des enseignants. Les auteurs suggérent des stratégies pratiques dans l’introduction de discussions asynchrones dans un environnement CMC. Die Qualität der übermittlung von Ideen, Denken und Interaktion in einem asynchronen CMC Umfeld Eine der wichtigsten Umstellungen der heutigen Ausbildung ist die unter dem Einfluss von Informations- und Kommunikationstechnologien verstärkte Tendenz, rechnergestützte Kommunikation (computer-mediated communications:CMC)

zu benutzen. CMC hat ein ganzes Arsenal von Methoden entwickelt, von der einfachen E-Mail bis zu drahtlosen Nachrichten und synchron oder asynchron geführten Diskussionen. Die Forschung in diesem Bereich konzentriert sich hauptsächlich auf die pädagogischen Aspekte von CMC, besonders auf die Nutzung, die Strategien, den Wirkungsgrad und die Möglichkeiten der Einbindung der Neuen Technologien zum Lehren und Lernen. Einige Arbeiten erforschen die verschiedenen Perspektiven

der Interaktion wie das Verfolgen von asynchronen Diskussionen, die Qualität der Beteiligung, der Interaktion und Zusammenarbeit oder dem Lernen in Gruppen. In diesem Beitrag wird über Ergebnisse der Studie zur Untersuchung der Qualität der übermittlung von Ideen, Gedanken und Interaktionen in einem asynchron arbeitenden rechnergestützten

System (CMC) einer Lehrerfortbildungseinrichtung berichtet. Die Autoren erläutern praktische Strategien zur Einbindung asynchroner Diskussionen in eine CMC-Umgebung.  相似文献

Biodeterioration of Incralac used for the protection of bronze monuments   总被引:2,自引:0,他引:2  
Outdoor bronze sculptures are highly susceptible to corrosion in many environments and organic coatings are widely used for their protection. The purpose of this study was to determine the susceptibility of the commonly used coating Incralac to biodeterioration by microorganisms. A yeast was isolated from a bronze statue treated with Incralac and its ability to degrade Incralac was determined using growth curves, scanning electron microscopy (SEM), and electrochemical impedance spectroscopy (EIS). The organism grew slowly on Incralac in liquid culture, but SEM images demonstrated its ability to adhere to Incralac coated metal. Additionally, the yeast caused a rapid drop in the low frequency impedance of Incralac coated metal that was not observed under sterile conditions, indicating that the organism accelerated deterioration of the coating. The potential for microbial growth to accelerate deterioration of Incralac should be considered when developing a maintenance strategy for the protection of outdoor metal monuments.  相似文献

International students enrolled in programs accredited by the Council for Accreditation of Counseling and Related Educational Programs provided acculturative stress and needs data. Acculturative stress was correlated with academic, social, language, and cultural needs. Furthermore, relationships were found between students’ types of needs. Implications are offered to help meet international students’ needs.  相似文献

This paper presents the findings of a research project on older workers transitioning into work as vocational educators through online undergraduate university study. The study involved interpretive phenomenological analysis of the experiences of 10 older learners. Their experience of online learning was found to be shaped by diverse influences and to comprise three distinct but interrelated elements: their use of technology, their use of hypermedia and their independent learning. Challenges raised by each of these elements called for a distinctive response from the university, respectively: short-term, readily available technical advice and support; tutoring to develop Web navigation and exploration skills, or the provision of selected readings; and opportunities for online or face-to-face dialogical engagement with others. Recommendations for the online provision of higher education for such learners, then, pointed to the need for an appropriately distinctive response to challenges in each of the three elements: the use of technology calling for individualised and immediate responsiveness to learner issues; the use of hypermedia calling for aggregated advice and resources prepared in advance; and independent learning calling for the prior structuring of opportunities for interactive engagement. Further research is suggested focusing on the relative cost and effectiveness of different approaches to addressing those needs.  相似文献
