The study proposed and tested 2 hypotheses to account for the claim by Appel, Cooper, Knight, McCarrell, Yussen, and Flavell (1972) that "memorizing and perceiving are functionally undifferentiated for the young child" by presenting preschool, second-, and fifth-grade children a "memory" and a "look" problem under several treatments in which semantic category cues were present. Surprisingly, preschoolers showed functional differentiation even in the absence of semantic cues--a finding interpreted as evidence for a functional differentiation in the young child's deployment of attention. Second and fifth graders also exhibited functional differentiation in the absence of semantic cues, and there were age changes in the facilitating effects of input and retrieval cues on children's memory. 相似文献

Photoresist technology, which is used for micro-patterning exploits changes in properties of polymeric materials, such as their solubility or volatility, upon photo-irradiation. This process has greatly benefitted from the knowledge base of organic chemistry and photo-induced organic transformations. The role of chemistry in the development of photoresists is described in this article. 相似文献

AbstractMany studies have found a relationship between students’ self-reported procrastination and their grades. Few studies have used learning analytic data as a behavioural measure of procrastination in order to predict performance, and there is no systematic research on how this relationship may differ across assessments or disciplines. In this study we analyse nine years’ worth of institutional electronic submission records, a total of 73,608 assignment submissions, to examine the relationship between submission time and grades across assignments, students, courses, and disciplines in higher education. A significant negative relationship was found overall, with students who submitted closer to the deadline obtaining lower grades, however the size of the relationship was negligible, accounting for less than 1% of the variance in grades. The relationship varied significantly depending on student, assignment, course and discipline. 相似文献

Poverty reduction is deeply implicated in structures of politics, economy, culture, and technology, from the global down to
local levels. Irrespective of the particular political ideology of a nation and of the specific strategy of mobilization,
adult and life-long education can and must play a significant role in reducing poverty, including preventing its inception.
Yet the adult-education sector does not seem to be ready for this challenge. The present study argues that the re-education
of adult educators is a dire necessity for effective poverty reduction. It also maintains that adult educators must be re-socialized
in terms of their potential new roles as intellectual-activists. Only so can they work successfully towards introducing systems
of adult and life-long education that are truly comprehensive and genuinely commensurate with the goals of poverty reduction.
Zusammenfassung ERWACHSENENBILDUNG UND LEBENSLANGE BILDUNG FüR DIE VERMINDERUNG VON ARMUT: EINE KRITISCHE ANALYSE VON ZUSAMMENH?NGEN UND BEDINGUNGEN – Die Verminderung von Armut ist tief verankert in den Strukturen von Politik, Wirtschaft, Kultur und Technologie, von der globalen bis hinab zur lokalen Ebene. Ungeachtet der jeweiligen politischen Ideologie einer Nation und der spezifischen Strategie zur Mobilisierung kann und muss die Erwachsenenbildung und die lebenslange Bildung eine bedeutende Rolle dabei spielen, die Armut zu vermindern, was mit einschlie?t, ihrer Entstehung vorzubeugen. Dennoch scheint der Sektor der Erwachsenenbildung für diese Herausforderung nicht gerüstet zu sein. Die vorliegende Untersuchung legt dar, dass die Neuausbildung der Erwachsenenbildner eine unbedingte Notwendigkeit für eine wirksame Verminderung der Armut darstellt. Sie stellt auch fest, Erwachsenenbildner auf ihre m?gliche neue Rolle als Bildungsaktivisten neu vorbereitet werden müssen. Nur so k?nnen sie erfolgreich darauf hinarbeiten, Systeme von Erwachsenenbildung und lebenslanger Bildung einzuführen, die wirklich umfassend sind und den Zielen der Verminderung von Armut tats?chlich entsprechen.
Resumen EDUCACIóN DE LAS PERSONAS ADULTAS Y DURANTE TODA LA VIDA PARA LA REDUCCIóN DE LA POBREZA: UN ANáLISIS CRíTICO DE CONTEXTOS Y CONDICIONES – La reducción de la pobreza está profundamente implicada en las estructuras de la política, la economía, la cultura y la tecnología en todos los niveles, partiendo desde niveles globales y bajando hasta los niveles locales. Independientemente de la ideología política particular de cada nación o de la estrategia específica de movilización, la educación de las personas adultas y durante toda la vida puede y debe desempe?ar un papel importante en la reducción de la pobreza e incluso en la prevención de sus comienzos. Sin embargo, el sector de la educación de las personas adultas aún no parece estar preparado para enfrentar estos retos. Este trabajo sostiene que la reeducación de los educadores adultos es imperiosamente necesaria para lograr una reducción eficaz de la pobreza. También sostiene que los educadores adultos deben ser resocializados en cuanto a sus potenciales nuevos roles como activistas intelectuales. Solamente de esa manera podrán trabajar con éxito para implantar sistemas de educación de personas adultas y durante toda la vida que sean realmente completos y que, efectivamente, cumplan con los objetivos de reducción de la pobreza.
Résumé éDUCATION DES ADULTES ET TOUT AU LONG DE LA VIE EN FAVEUR D’UNE RE′DUCTION DE LA PAUVRETé : UNE ANALYSE CRITIQUE DES CONTEXTES ET DES CONDITIONS – La réduction de la pauvreté est profondément impliquée dans les structures de la politique, de l’économie, de la culture et de la technologie, du niveau global jusqu’aux niveaux locaux. Indépendamment de l’idéologie politique particulière d’une nation et de la stratégie spécifique de mobilisation, l’éducation des adultes et tout au long de la vie peut et doit jouer un r?le significatif dans la réduction de la pauvreté, y compris en empêchant son commencement. Cependant, le secteur de l’éducation des adultes ne semble pas être prêt pour ce défi. L’étude présente soutient que la rééducation des éducateurs d’adultes est une dure nécessité pour la réduction effective de la pauvreté. Elle maintient également que les éducateurs d’adultes doivent être resocialisés en termes de leurs nouveaux r?les potentiels en tant qu’activistes intellectuels. C’est seulement ainsi qu’ils peuvent travailler avec succès afin d’introduire des systèmes d’éducation des adultes et tout au long de la vie qui soient vraiment complets et véritablement adaptés aux objectifs de la réduction de la pauvreté.相似文献

An undergraduate teacher education program at Gallaudet University prepares deaf students in "regular" education. This includes a required full-time internship with hearing students (assisted by sign language interpreters). Graduates then continue in a master's degree program in deaf education, thus acquiring dual certification. Several studies indicate that these deaf candidates progress through the same developmental stages as hearing candidates and that they develop high expectations for deaf learners. Issues related to implementing such a program are discussed. 相似文献

This study compared the performance of children with reading disability (RD) and normal reading achievement (NRA) on tasks
of serial rapid naming, verbal fluency, letter-based word retrieval, and articulatory speed. The groups, composed of children
at two discrete age levels, one younger and one older, were matched for age, gender, and neighborhood school. Analyses of
the on-line measurement of the children’s serial rapid naming indicated that the children with RD had significantly larger
reaction times and production durations than their NRA peers despite similar levels of accuracy. They also performed significantly
worse on the categorical verbal fluency task, the letter-based word retrieval task, and the test of articulatory speed. The
findings suggest that both access and post-access processes, such as oral-motor inefficiency that extends the duration of
word production, may be implicated in the slower serial rapid naming that has typified many samples of children with RD.

Four pigeons responded on a two-component multiple token-reinforcement schedule, in which tokens were produced according to
a random-interval 30-sec schedule and exchanged according to a variable-ratio 4 schedule in both components. To assess the
effects of contingent token loss, tokens were removed after every second response (i.e., fixed-ratio 2 loss) in one of the
components. Response rates were selectively lower in the loss components relative to baseline (no-loss) conditions, as well
as to the within-condition no-loss components. Response rates were decreased to a greater degree in the presence of tokens
than in their absence. To control for the effects of changes in the density of token and food reinforcement, two parts consisted
of additional conditions where food density and token loss were yoked to those in a previous loss condition. In the yoked-food condition, tokens were produced as usual in both components, but the overall density of food reinforcement in one of the
components was yoked to that obtained during a previous token-loss condition. In the yoked token-loss condition, tokens were removed during one component of the multiple schedule at a rate that approximately matched the obtained
rate of loss from a previous token-loss condition. Response rates in these yoked components were less affected than those
in comparable loss components, despite similar densities of token, exchange, and food reinforcement. On the whole, the results
support the conclusion that contingent token loss serves as an effective punisher with pigeons. 相似文献
