We are particularly interested in looking at teaching and
learning from students perspectives. Focussed interviews and written
responses from a number of linked investigations with middle-school
and tertiary students highlighted that students perceive discussion
to be a valuable teaching -- learning technique. This paper provides
text extracts, organised into six key themes, to illustrate students
understandings about how discussion helps them to learn. We conclude
that, across the whole participant group, knowledge about the various
potentials of discussion for learning is wide ranging. However, at
the individual level, some students perspectives appear limited. We
propose that specific attention to enhancing students pedagogical
knowledge about techniques such as discussion should accompany
subject matter instruction. 相似文献

Motor performance on simple tasks improves after training in variable practice. We asked if locomotor skill during an obstacle-avoidance task in a novel sensorimotor environment improved through training in variable practice on other complex tasks. 40 normal adults practiced gross motor skills while wearing either sham lenses, one of several visual distortion lens (constant practice), or three different visual distortion lenses (variable practice). Posttests on obstacle avoidance with novel lenses showed significantly better scores with variable practice and one of the constant groups vs sham lenses. Constant and variable practice groups did not differ. Thus, performance in a novel environment improves after training on similar type novelty, even when practice and test conditions differ. Constant practice was effective only if the subjects used the lens efficacious in training. Variable practice increases the likelihood of efficacious training when adaptive performance is required in a novel environment. 相似文献

This article presents and interprets the case study of an elderly woman's story of suffering. It results from interviews conducted with African-American and Caucasian men and women, aged 70 and above, concerning their personal definitions, attributions, and theories about suffering. Elders' experiences of suffering were examined under the rubrics of gerontology, narrative, and religious studies. Key themes offered in this case study are: (a) How the life course unfolds because of or despite suffering, (b) what moral status an elder confers on past or present suffering, (c) how a personal sense of the sacred accommodates suffering, (d) how this particular respondent alters her identity based on assimilating the new information of suffering, and (e) how the story of suffering stands out against or blends in with the backdrop of the life story. The uniqueness of this case study also mirrors commonalities of elders' narratives of suffering, particularly those of women. This elder's story demonstrates that smaller individual suffering is rooted in the frame of the larger public world. It also illustrates that the language women use to attribute, define, and theorize suffering is embedded in relationships. 相似文献

Conditioning may generalize from one context to another when latent inhibition (the effect on subsequent conditioning of prior unreinforced exposure to the stimulus) does not. Experiment 1 studied conditioned approach and licking by rats to a stimulus paired with the delivery of water and confirmed that latent inhibition could be abolished by a change of context, while prior aversive conditioning to the stimulus, produced by pairing it with mild shock, interfered with the acquisition of conditioned approach and licking regardless of this change of context. Thus even when conditioning and latent inhibition were measured in the same way, the former generalized across contexts, and the latter did not. Experiment 2 showed that the effects not only of unreinforced exposure to a stimulus but also of presentation of the stimulus uncorrelated with the delivery of water were confined to the context in which they occurred. Thus the generalization of conditioning from one context to another and the failure of latent inhibition to generalize cannot be attributed to the occurrence of rein-forcers during conditioning and their absence in latent inhibition. This conclusion was confirmed in Experiment 3, where animals received both aversive conditioning trials and unreinforced presentations of other stimuli in the treatment phase of the experiment, but were then conditioned to one of these stimuli paired with water. Once again, the effects of aversive conditioning transferred perfectly from one context to another, while those of unreinforced presentations did not. Latent inhibition, these results suggest, is not easily explained by supposing that animals associate an unreinforced stimulus with zero consequences and have to unlearn this association when the stimulus is then paired with a reinforcer. 相似文献

While humans rely on vision during navigation, they are also competent at navigating non-visually. However, non-visual navigation over large distances is not very accurate and can accumulate error. Currently, it is unclear whether this accumulation of error is due to the visual estimate of the distance or to the locomotor production of the distance. In a series of experiments, using a blindfolded walking test, we examine whether enhancing the visual estimate of the distance to a previously seen target, through environmental enrichment, visual imagery, or repeated exposure would improve the accuracy of blindfold navigation across different distances. We also attempt to decrease the visual estimate in order to see if the opposite effect would occur. Our results would indicate that manipulation of the static visual distance estimate did not change the navigation accuracy to any great extent. The only condition that improved accuracy was repeated exposure to the environment through practice. These results suggest that error observed during blindfold navigation may be due to the locomotor production of the distance, rather than the visual process. 相似文献

Abstract Within many intimate dyadic relationships, individuals talk to their partners about a past relationship with a former spouse or lover. The impact that “talk about a past partner” (Tapp) has on one's current relationship is reviewed. Four metacommunicative functions of Tapp are suggested: disclosing past relationship history, conveying relationship rules or expectations, creating closeness or distance, and confirming self-perceptions. It is argued that the role of Tapp, within any given relationship, not only affects partners' feelings of security, control, closeness, etc., but also may reveal their characteristic patterns of communicating, metacomrnunicat-ing, interpreting and misinterpreting. 相似文献
