Continuing emphasis given to computer technology resourcing in schools presents potential for web-based initiatives which focus on quality arts teaching and learning, as ways to improve arts outcomes for all students. An arts e-learning collaborative research project between specialist on-line teacher/researchers and generalist primary teachers was designed to investigate student learning, quality teaching, and implementation factors. Constructionist-based teaching activities using on-line technology were designed to engage students in a learner-centred e-learning environment where students and teachers collaborated to produce a media and learning artefact. A case study highlights the outcomes for four students who transferred learnt drama skills to other classroom contexts. This model has potential to provide drama learning for students and professional development for primary generalist teachers, contingent on the availability of rigorously planned and well-resourced programmes. 相似文献

Prior research has demonstrated renewal, which is the ability of contextual cues to modulate excitatory responding to a Pavlovian conditioned stimulus (CS). In the present research, conditioned lick suppression in rats was used to examine similar contextual modulation of Pavlovian conditioned inhibition. After Pavlovian conditioned inhibition training with a CS in one context, subjects were exposed to pairings of the CS with an unconditioned stimulus (US) either in the same or in a second context. Results indicated that, when the CS was paired with the US in the second context, the CS retained its inhibitory control over behavior, provided that testing occurred in the context used for inhibition training. However, when the CS-US pairings occurred in the inhibition training context, the CS subsequently proved to be excitatory regardless of where testing occurred. These observations indicate that conditioned inhibition is subject to renewal. 相似文献

Lick suppression experiments with rats revealed that the magnitude of both second-order conditioning (Experiment 1) and sensory preconditioning (Experiment 2) was superior when that conditioning was based on backward (US→CS) relative to forward (CS→US) first-order pairings of a CS and US. The superiority of backward relative to forward first-order conditioning on suppression to the higher order cues can be understood by assuming that the magnitude of higher order conditioning was determined by a memory representation of the higher order cues that provided information about the expected temporal location of the US. The results suggest that temporal information such as order between paired CSs and USs was encoded, preserved, and integrated with memory for the higher order stimuli. The relevance of these findings to memory integration in Pavlovian learning, the temporal coding hypothesis (Barnet, Arnold, & Miller, 1991; Matzel, Held, & Miller, 1988), backward excitatory conditioning, and the associative structure that underlies second-order Pavlovian fear conditioning are discussed. 相似文献

Navigating the unfamiliar in a quest towards culturally responsive pedagogy in the classroom 总被引：1，自引：0，他引：1
This paper examines a New Zealand Pākehā (European) teacher's professional development experience working with Māori (indigenous people of New Zealand), and their protocols and practices. A Māori kaumatua (male leader) experienced in theatre direction, acting, and psychiatric nursing led Māori marginalised youth to disclose their personal stories, wrap them in tikanga (customs) and move forward to create theatre from their experiences. This paper discusses a participant observer process of living on a marae (Māori congregational place), working with Māori, experiencing Māori protocols and practices on a daily basis, and the recommendations for teachers dealing with cultural difference in the classroom. 相似文献

This article develops and tests the argument that leadership behavior in organizations can best be understood within a contingency technology-environment model. The major premise of this model is that one of the most influential intervening factors between organizational performance and leadership behavior is either the technology that the organization utilizes or the environment with which the organization interacts. Building upon this premise and the work of Kuhn (1970), four hypotheses are tested concerning the relationship between the effectiveness of natural science and social science departments in American universities using factor analysis. The data supports the conclusion that differential leadership styles are predictable in different scientific fields. 相似文献

Water-deprived rats were used to investigate the effects of training a CS in more than one context on conditioned lick suppression. In each experiment, partial reinforcement of the CS was intermingled with unsignaled presentations of the US. In Experiment 1, subjects were either trained in one context alone, trained consecutively in two contexts (such that all training in one context occurred prior to any training in the second context), or trained alternately in two contexts. Following training, the first context, the second context, or neither context was extinguished. Testing of the CS occurred in a third (neutral) context. To the extent that either training context became established as a comparator stimulus for the CS, the comparator hypothesis (Miller & Matzel, 1988) predicts an increase in excitatory responding to the CS following extinction of that context. Subjects trained in a single context exhibited appreciable fear of the CS only when the CS’s training context had been extinguished. Additionally, subjects trained consecutively in the two contexts showed increased fear of the CS following extinction of the second, but not the first training context (i.e., a recency effect). Subjects trained alternately in the two contexts showed no increased fear of the CS as a result of either context alone being extinguished. In Experiment 2, subjects trained alternately in two contexts showed increased fear of the CS only when both training contexts were extinguished, suggesting that both training contexts had become comparator stimuli. These data indicate that multiple training contexts can either compete or act synergistic-ally in modulating responding to a Pavlovian trained CS as a function of the order of training in the different contexts. 相似文献
