This paper examines the ways in which the interpretation of a literary text is constructed through social interaction in a multi‐ethnic urban secondary school English classroom. The focus is on the literacy experiences of Year 10 students (age 14 to 15 years). We take a multimodal approach to understanding social interaction around texts and show that higher‐order literacy skills are realised and constructed through the configuration of talk and writing with a range of other representational and communicational modes, such as gesture, gaze, movement, and posture. We suggest that despite the exhaustive regulation of literacy and school English, some English teachers, while still curriculum and examination focused, have found strategies that give them space to make connections between texts and the experiences of their particular student intake. They do so in ways that link to wider social and moral issues, drawing on their own and their students' life experiences, to make cultural connections with the texts studied. The paper shows how a multimodal analysis of social interaction facilitates and extends understanding of the teaching that is taking place. 相似文献

Rats were used to examine the extent to which extinction of an acquired conditioned taste aversion retards subsequent reacquisition. A saccharin-flavored solution (sac) was paired with LiCl and then followed by CS-alone extinction trials with this flavor. A control group received a different flavor, decaffeinated-coffee (coff), during initial conditioning and extinction. Sac was then paired with LiCl for all rats during a second conditioning phase. Reacquisition of the aversion to sac was retarded relative to the acquisition of an aversion to sac by the control group. A similar experiment with fewer extinction trials, but still with complete loss of the initial aversion, did not obtain slow reacquisition. The results are discussed with respect to an interference view of extinction and the slow-reacquisition effect. 相似文献

The recent developments in this area in terms of curricular changes in the Electrical Engineering program have been described and evaluated. A previous required course, which covered electric machinery in some detail, has been replaced by a more general course which studies the principles of electromechanical energy conversion and the control of the flow of electrical energy by both static and motional devices. In addition, a new experimental two-semester course has been developed which integrates the study of energy conversion and control devices into a study of systems and the role of these devices in meeting system specifications. 相似文献

The goal of the project examined here was to establish performance standards for Navy aerographer's mate (AG) enlisted sailors at three skill levels. We used an online expert judgment task and consensus workshop methodology to gather information from subject matter experts on minimal proficiency requirements for each task within each skill level. Analysis of these judgments found a high degree of rater agreement on these standards, and resolution of any disagreements was accomplished in a consensus workshop. 相似文献

Using a conditioned taste aversion preparation overshadowing of flavor-illness association was produced through the presentation of a second flavor during the interval between the first flavor and illness. The modulatory effects of extinguishing the association between the second (over-shadowing) flavor and illness on conditioned responding to the target flavor was investigated. In Experiment 1, we found that, following one-trial overshadowing, extinction of the overshadowing flavor had no effect on conditioned responding to the target flavor. In Experiment 2, we found a similar absence of an effect of extinction of the overshadowing stimulus in a multitrial over-shadowing paradigm. Experiment 3 confirmed the results of Experiments 1 and 2 using conditioning parameters that were designed to weaken the association between the overshadowed flavor and illness. In Experiments 4 and 5, we used simultaneous presentation of the flavors during conditioning and obtained a weakened aversion to the overshadowed flavor when the overshadowing CS was extinguished. These findings are inconsistent with previous observations in conditioned fear preparations that suggest that extinction of the association between the overshadowing stimulus and the unconditioned stimulus attenuates overshadowing. Possible reasons for the discrepant results are discussed. 相似文献
